Wanted: Blizzard PPC in lowest config: 040LC@25MHz PPC@160MHz no SCSI

[stachu100]

Yes, 66 Mhz shoud work with SCSI also, but results may differ:

Thank you very much!
Yes, SCSI is working even with 72MHz

Just quick playing with SCSI settings is enough to have it working.

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.
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 much ram do you have now?   let me guess you have just limited the card 128Mb.
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.

Well, first of all I'm not software geek.
 
Second when I read test guidelines about this test that "lower value are better."
See the statement:

@Delshay,
I really don't want to compete who is the best; I'm just doing my job as best I can.

YOU MUST STATE WHICH OS YOU ARE USING WHEN DOING THE TEST.

[stachu100]

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  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!

[Bamiga2002]

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?

[delshay]

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.
