Hi,
I'm looking for card in above mentioned config.
Reason:
I would like to test possibility to change the PPC processor to 300MHz version.
Europe vendors preferred.
Regards, Stan
-
there's no need to test,it will work ( both processors ).
did you fix the PPC on the Cyberstorm PPC?. if so what was the problem?

I know.
My target was to upgrade PPC procesor (un-solder old one and solder new) just to check my soldering skills :)
Now it's done:
http://picasaweb.google.pl/stacho100/BlizzardPPC_06066MHzPPC300MHz#
http://www.youtube.com/watch?v=ewuwDs6QNgM (http://www.youtube.com/watch?v=ewuwDs6QNgM)
Initially this card was 040@25MHz/PPC@160MHz with bus speed 50MHz for PPC processor (lowest config posible).
Now it's the best config possible:
060@66MHz/PPC@300MHz with 60MHz PPC bus speed :)
060 CPU and 060 oscillator are socketed just in case (some BVision cards refuse to work on 66MHz).
I tried this PPC processor to work with 66MHz bus speed, but cards hung-up after 2 minutes; so I was forced to set 60MHz oscillator for PPC with x5 clock multiplier.
Just missing the heatsink+clips+5Vfan for PPC processor; I bought this card without it.
If you have it as spare I'm ready to buy ;)

Excellent job!
-
Geez. I thought this was impossible... not even amigacenter can do it!
Maybe you can help many amigans with dead ppc's on their boards.
How much would you charge for an upgrade job of a low end bppc or an overclocking job?
I guess you use professional tools to do this.. right?
Absolutely awesome!
Cheers,
Dragster
-
wow very nice! where did you get so many of those ppc cpus :)
is it faster than 604e 233MHz ?
-
WOW! Great job!!!!!!
You should consider on helping others to fix their Blizzard cards for a fair price.
Your work can be considered a piece of art.
Keep it up!

There's a PPC/040 A1200 card on ebay with issues. It only works when held in a certain position.
-
Now it's the best config possible:
060@66MHz/PPC@300MHz with 60MHz PPC bus speed :)
that all depends if your into overclocking the PPC processor.
NOTE: that in this mode the speed of the PPC processor will not show up in OS4.0 did not check OS3.9 the fault seems to be in the BlizzardPPC firmware (possible new flashupdate needed)
here i have simms that go as low as 43ns which allows 82Mhz+ bus (ram settings free config all turned off) but the bus speed has reached 83.66Mhz (43ns simm)and sets a new world record for a A1200, its about 2 sec quicker than my standard PPC 320Mhz (80Mhz osc ) 060@70Mhz. (45ns simms)
this new speed you are going to find that there is a very small number of Bvision that shows errors or lock-up the system which i have partly solved with my latest modifcation,this also improves overclocking the Bvision under OS3.9.
how fast the bus speed will go will also depends on what revision of the A1200 motherboard you have,this is why i have a Blizzard with both processors clocked at a set speed,i done this in order to try and find out what the problem is,but it will take time to find out what the problem is with some revision of A1200 motherboard.
with my ever improving blizzard my focus is to make the card very stable,and it is very stable no lock-ups as i find this very important as well as timing issues,and must pass 24hrs test.
WARNING! with extreme speed you must have the correct cooling (mandatory) if you fail to add the correct cooling you will damage the card.
***all modification at your own risk***
-
@delshay
So, which A1200 revision motherboard is best suited for this kind of extreme overclocking experiences?
-
wow very nice! where did you get so many of those ppc cpus :)
is it faster than 604e 233MHz ?
the question is where did i get PPC 740 500Mhz (my next project)
dont think so, Blizzard will be slower than 233Mhz cyberstorm,but if you have a cyberstorm 233Mhz do a FFTdemo and upload to the correct thread on another amiga website.
-
U got PM
-
speed test Blizzard vs Cyberstorm
need test of Cyberstorm 233 to overcome Blizzard. also look at last page to see inproved result with increased speed.

@delshay,
Everything you wrote is true.
What I wanted to do is to make an upgrade/repair for polish Amiga community; that is why I've ordered bigger batch at one shot.
And hopefully for me I wasn't cheated.
With concerns timing and memory:
Well, I've checked this particular card with 60ns standard SIMM.
I have 64MB 50ns SIMM as well (from some old SCSI controller), but to be honest my target was to do this upgrade/repair for people with standard SIMM's available on the market even scarifying performance.
Maybe with better (faster) SIMM's the card might work ok with both 66MHz oscillators, or even 70MHz; who know?
My intention was not to create "super card", but to resurrect broken cards and for PPC@160Mhz (PPC@160Mhz) users to give them a chance for upgrade at reasonable cost.
by the way:
Your project to install 740 500MHz CPU on the Blizzard PPC is really impressive!
In this case my card is not the best config; your is.
-
removed posting.

WOW! Great job!!!!!!

Keep it up!
after buying many faulty Blizzard cards iv found not all faults was on the CPU. in most cases the CPU turn out not to be faulty,i only found one card that had a faulty CPU and in another the CPU had a cracked joint.
but i have found faults in places where you think thats impossible.
i have rebuilt 2 cards from scratch one i had to add the complete SCSI
some companys will not touch old PCB because of the age of the card,and doing BGA re-work if something go`s wrong you must know how to repair it.
ACUBE was doing CPU upgrade but if the CPU turns out not to be faulty and the fault was somewhere else on the card how will the card be returned (with new or old CPU) with the card still not working.

Thanks a lot for this info!
People from Poland are asking me to repair their broken cards, but my answer was always that repair is not possible; what I can offer is to replace CPU and if this will not help just to look around to find unsure solder joints, broken cooper tracks, defective trough-holes in PCB or even faulty eeprom.
I agree, repair of such cards is like lottery: prize is high, but probability to win is significantly lower than 100%
We are not David Copperfield :)
And small update:
I've managed to run PPC at 330MHz (5,5x60MHz):
http://www.youtube.com/watch?v=SloiWlPkG18 (http://www.youtube.com/watch?v=SloiWlPkG18)
I'm not going to test it at 360MHz, however as card was stable for 1,5h under AOS3.1/4.0, so I can say that it's possible.
And I'm using standard "light" A1200 power supply.

can you download the FFTdemo and do a test and upload please state what OS you are using... link is in this thread
I also have 3 spare 300Mhz CPU so any UK users that needs a upgrade can contact me.
-
interesting thread/project! keep it up the good work. Congratulations to both of you :)
@delshay
absolutely right about not beeing the CPU at fault (most of the times).
As soon as i get some free time (close to retiring), i'll try to get a broken CSPPC and some 604e (no clue how ATM) and attempt the "miracle"
-
What would be reasonable speedwise to run this 300Mhz processor?
@4.0x75Mhz bus speed
@4.5x66,666Mhz bus speed
@5.0x60Mhz bus speed
all equal to 300Mhz but what kind of memory will cope with a specific bus speed setting and allow to disable precharges? and how about 5.5x60Mhz (=330Mhz) and its memory settings in bootmenu?

i spent a lot of time and money researching this over the last 3 years,i was hopeing to get some return on my investment by doing upgrades and repairs.,but it now looks unlikely now so i have removed some of my notes from this thread.
the answer to your question mite be one the link below and that is not it's top-end speed if i feel i need extra horsepower i can step it up. iv seen the benchmark of what it can do.

Hi,
how much to replace my working bppc 603e-210(@224) by a 300 one ?
-
Holy cow, those are some bad assed blizzards :-o
Would there be any improvement (aside from the obvious speed up of the 68K processor) if you ran the 68K part from the same clock crystal as the PPC? I've often wondered about that. There must be some wait states / latencies involved when managing two different FSB speeds into the same memory.
-
Well, you are probably right.
But 60MHz is the fastest PPC bus settings with standard RAM SIMM's.
I prefer stable work than additional 10% of power and unsure stability.
-
Wow Im shocked to here some of thought this was difficult. Just need either a reworker station and some solder paste, steady hand and plenty of staring at the board with a magnifying glass ;)
However I am quite happy popping atmel's and tsop flash chips for 10 a penny motherboards, but ppc....u get one shot and if you cook the chip back to low or no speed.
Anyone try it with a infrared Heat station, there the in thing for BGA chips ?
-
another problem has been found and removed,this will improved performance and set another new record for classic amigas PPC.
i don't know if morph OS will do a small update but i will contact HYPERION and push for this update as i feel it very important.
if morph OS team still support the classic amiga please contact me via pm i think it will be a small rewrite of the software or maybe its already in the software as i never tried morph OS.
i will be doing upgrades in late march,i just need to find and fix the last remaining problem on the A1200 motherboard.
all Blizzard PPC cards upgraded by me will get the FULL upgrade.
-
Anybody ever play with this kind of stuff on the CSPPCs? Same idea?
-
anyone knows where to find a ppc 740?
I have tried before to change the 603 with an 740 with mixed results.
I manage to run the amiga with 740 and even got some syspeed benchmarks, but it was unstable like hell. and I decided to revert it back to 603
it was some years ago, maybe 6-7, but I still have the syspeed module
-
That's very interesting. Could u be more specific as to how you managed to swap 603 with 740? Was it just a simple soldering? Or did you have to do anything else? I'm quite sure that both Stachu100 and delshay could benefit a lot from your experience.
Maybe the the problem of non-stability was the right choice of memory. Stachu100 mentions a lot about it.
Anyway, that idea of putting 740 into BlizzardPPC or CSPPC is absolutely great!
-

I'm going to try to put 604e 300MHz into Cyberstorm and hope to have 330MHz speed running stable with standard cooling.
Proper processors are one way to me already :)
I will keep you posted about Cyberstorm upgrade progress.
I have no intention to experiment with other processors type as it might be unstable/impossible/kill the processor/kill CSPPC board/kill both.
I don't care to kill the processor, but I don't want to sacrifice my CSPPC for sure! :afro:

Great! Keep us posted on how you get along :)
im not going to give anything away anymore as i spent a lot of time and money and i want to see some return.
all im going to say is that it for the Blizzard but it now drags the Cyberstorm in as well. (im almost sure it`s going to need a software update).
NOTE: my Blizzard cards have a nasty hack which allows me to have a FPU on the A1200 motherboard so i don`t have to remove the co-processor on the A1200 motherboard.
so when the Blizzard card is disabled by holding down the 2 key,the A1200 020/FPU becomes active. this hack will be on my cards only untill it improves.
there will be one month testing before anything is released.
-
..as if there were a ton of people waiting in the wings with the skills and inclination to repair PPC cards!

What kind of software update are you refering to?
Unfortunately there is no support ny MorphOS team for MorphOS PowerUP (MorphOS for classic Amgas) any more.
And I doubt that Hyperion will care about any kind of update for 4.0 classic. They are focused ito this X1000 stuff right now.
:(
-
Well, at least MorphOS for the classics has a SCSI driver for the 1200 ppc card.

blizzard ppc speed test OS4.0 now can someone with a cyberstorm 233 do the test.

Hi All,
I've managed to upgrade another two boards :-)
To eliminate BGA soldering problem to zero I decided to change PPC processor with help of professional service center.
My tools are ok, but why not use better if it's possible?

And another 2 movies:

http://www.youtube.com/watch?v=BvCUaePyvKo
Cards after upgrade:
http://picasaweb.google.com/stacho100/BlizzardsPPCAfterUpgrade#
I used MC68060RC60 with mask 71E41J (rev 6) working natively at 60MHz taken-out from some industrial CPU boards; on the center of CPU you can see mark from heatsink glued onto 060 (I've took the heatsinks out of course).
As it was expected; Blizzard PPC with SCSI version cannot work with 060 clock higher than 50MHz :-(
I was trying even to erase Serial Number with flashing with "Force" option on one board to see if this will disable the onboard SCSI controller, but unfortunately this is not the case...
So bad news for Blizzard PPC with SCSI users (603e+): your card cannot work with 060 clock higher than 50MHz...
If someone is really not using SCSI in the desktop case maybe the best option for him is to remove onboard SCSI.
By doing so it's possible to increase 060 clock to 66MHz, and having very good RAM even higher frequencies are possible :-).
-
@stachu100
That isn't entirely correct though as I have a perfectly working 603e+ with 060@66MHz, working also @75MHz if I remove one of 2 128mb simms. 060 isn't even rev.6, it's rev. 5. SCSI works fine of course reaching almost the bus limit of 10MB/sec (9,7MB raw read according to drivespeed utility).
So, maybe there are other factors limiting the clock speed in your case.
-
Well, the cards which I have just refuse to work even with 60MHz oscillator and different memory config with even no memory at all (checked several times).
Always get SetPatch error...
Your post is very interesting, I will dig more about it; thank you!
-
Yes, 66 Mhz shoud work with SCSI also, but results may differ:

you are correct. there are many things that affect the card,and im going to tell **all** Blizzard PPC owners.
here i have very high speed cct on my Blizzard card and possibly 99.99% of you have the wrong type of simm(s) for VERY HIGH SPEED cct. some of you may have the correct simm(s) but don't even know it.
look at that speed test it's a *new** world record set yesterday and my Blizzard has a SCSI. every time i fix a problem the card gets faster.
every day im finding and removing problems this will only improve any cards i release.
it has taken me 3 years to iron out most problems,and there are still one or two remaining.
you can not put a 300Mhz processor on a card and think thats it. what about timing issues. i dont get any lock-ups none whatsoever but i can see timing issues. most programs will work fine,but i use a set of programs looking at timing issues.

With full memory settings (no read/write waitstates and no precharge) I had to remove the 2nd memory SIMM to make my miggy boot to WB, this was with 66Mhz.

Maybe SIMM was just on the edge of spec ant thus refused to work..
I did some performance tests of PPC@366MHz (PPC@366MHz).
It wasn't my intention to do so high overclocking, but I've got the card with one oscillator for PPC and 060...
And this card is don't care about soldered separate oscillaotr for PPC; always clock for PPC part is taken from 060 oscillator.
@delshay,
Please find the performance results you asked:
http://picasaweb.google.com/stacho100/BlizzardPPC06066MHzPPC366MHz#
Memory settings: "60ns"
SIMM USED: 64MB 50ns in single module.
Card was working 100% stable with these settings with desktop case without top; card was moderate hot with standard cooling during all tests (I could keep figers on both CPU without burning them).

how stable is the card?

looking at the FFTdemo test the first two results is very very poor it does not even beat a CyberStorm 150Mhz.
looking at my test it beats a CyberStorm PPC 150Mhz ( even with 256Mb ram) but no one with a CyberStorm 233Mhz wiil do the test (FFTdemo) perhaps their think CyberStorm 233Mhz will be outclassed.
the result for top end CPU speed is impressive but not the performance.
it looks like i have to prepare my other Blizzard and upload another test result. it's going to be the Blizzard with a BGA socket with it's Patent Pending cooler,and im sure it's going to take the test results even lower.

here is the latest test result which is already in this thread. Blizzard PPC OS4.0
Speed test for FFT + iFFT: (float)
time needed 16023ms for 413696 samples, => .292731136083602x speed @44100Hz/stereo
Speed test for FFT + iFFT: (integer)
time needed 13450ms for 413696 samples, => .3487309217453x speed @44100Hz/stereo
Speed test for FFT + iFFT: (integer handoptimized 68K ASM)
time needed 10865ms for 413696 samples, => .431700944900512x speed @44100Hz/stereo

I'm using AOS3.1, kickstart 3.0 softkicked to 3.1 A1200 1D4 motherboard.
It's pre-configured AmigaSYS 4 AGA.
Blizzard PPC clocked from one 66Mhz oscillator.
Memory set to "60ns" in Blizzard boot menu.
Single 64MB 50ns RAM module.
PPC@366MHz (PPC@366MHz) with bus clock 66MHz.
To be honest the PPC clock is 66MHzx5.5=363MHz, but these 3MHz are not so important...
Just one remark:
which is the benchmark result?
Is it this:
time needed 16023ms for 413696 samples, => .292731136083602x speed @44100Hz/stereo
or is it this:
time needed 16023ms for 413696 samples, => .292731136083602x speed @44100Hz/stereo
After checking the sentence of test result it seems that first is the test result...
As said I'm not software geek...
If so, your card is better as running with much higher bus speed 80MHz comparing to 66MHz in my case.
I know that in these conditions you have to use really good and selected RAM; otherwise 80MHz bus clock is just too much for popular RAM modules...

@Delshay,
Could you please present the hardware/software config on which you've got this excellent result?
Pictures (or movies) would be the best.
As you know very well I'm using freely available pictures/movies to show Amiga community what and how I'm doing.
I'm very curious about RAM used in this experiment.
And is there any other hardware hacks on the Blizzard PPC board (except replacing PPC of course)?
Did you decided to replace original Blizzard PPC logic chips by better and faster versions?
I know that's possible, but as I said before my intention is not to create "super board" but to repair/upgrade and left as much from orginal phase5 design as possible.
Thanks in advance!

how much ram do you have now? let me guess you have just limited the card 128Mb.
how stable is the card?
Yes i have 128Mb now, i think i can live with this :), not many progs need the full 256Mb. I just wanted to have max ram ;).
If you guys know what memory is good (manufacturer, brand, type, model etc.) for overclocking please state information here thanks!
and i had to put 60ns mem-settings in bootmenu, then the card was stable (some "minor" issues like if i ran Gears-PPC in a window and tried to start Exchange at same time --> hang).

@Delshay,
Very nice results indeed! :)
Is that mean no other hardware modification than PPC processor socket and PPC oscillator socket?
Can we have pictures of your hardware?
What about RAM used?

i can't answer any of your questions at this time as i need to gain back some of the money iv spent & research time. the information will be released after iv done a few upgrades. all upgrades by me will have everything.
UPDATE: the Bvision bug is almost found,if i can fix it this will be good news for a small number of Blizzard PPC/Bvision card owners.
the last test result i uploaded in this thread is final,the card will not go any faster and there is no lock-ups. any Blizzard card upgraded by me will not go as fast as the last test result. so as it's stands,it's the fastest Blizzard card in the world.
the only way the card can inprove is to find faster simms.

Don't get me wrong but why are u making such a big deal of taking one simple screenshot confirming your results? How do u want to get money back where there is no facts at all?
-
problem with Bvision has now being solved. there are now no issues with the card. there is one remaining issues which is the A1200 motherboard but this is not important at this stage.
so im ready to take list of users (via PM)that are interested,price of upgrade will be given before parts are ordered which will be mid march. there must be at lease 5 users that are interested.
during this time alot of testing will be done just to make sure there are no problems.

It would be really cool to see a bustest (http://aminet.net/package/util/moni/bustest) from one of these overclocked Blizzards.
There's a perfect thread to post your results over at the EAB (http://eab.abime.net/showthread.php?t=48407). ;)
