68EC060 to be placed on a Blizzard ? Good idea or not ???

[PulsatingQuasar]

A guy on Ebay from Germany had 5 of those 68060RC50 for sale with the mask 71E41J.

I bought 2 of them. Don't know if the sold the other 3.

Some people appear to be a little bit more lucky than I am  :bigcry:

You should have got a FULL MC68060RC50, with the Mask 1E41J.
These overclock to ANY speed you care to throw at them. They are totally cool at 50MHz.With a heatsink and fan, they overclock to 90/100MHz in other systems which have SDRAM (wont overclock past 70/80MHz on a blizzard due to low speed DRAM).

i'm thinking to overclock my bliz1260/50 for a long time, i even bought an oscilator/crystal @66mhz. i have 2x 32mb/50ns simms on and now that i see your post i wonder how can someone check the cpu if it is of that type. more than this, is it safe general speaking to overclock a 060 cpu no matter if the Mask isn't the 1E41J?

-edit-
i bought the bliz around may or june 1996

I could do with another 1E41J mask 060 but I cannot read german  :boohoo:

It's not. :cry: All amiga accelerators were made after this CPU was made.

Dunno about safe, but it will get hot, not recommended in a desktop situation.

PulsatingQuasar : thanks for your mail with the useful info  :-)

Amije : not all 68060´s can be overclocked to the same speed. I had my 68060 on a BPPC 240/060 overclocked by a friend and he couldn´t get it faster than 60 Mhz but that may be caused by the scsi controller on the card who doesn´t like overclocking  :lol:

Useful info?

[Effy]

He mailed me that the Ebay seller banshee121 often sells 68060´s  :lol: I mailed him back to thank him for the useful info and added the seller to my favorite sellers list  :-)

[PulsatingQuasar]

He sold those 68060 a couple of weeks ago. It was a "Buy now" product which you can't search for on EBay so if you search via his name you only see some other stuff.

But if I check via my history, the counter got stuck on 3 of 5 remaining. So they might not have been sold.

[Effy]

If I do a search on Ebay I also get to see the auctions with Buy Now option that are listed for sometimes even more than 30 days. Just click on THIS Ebay worldwide search for an 68060  :-o

[PulsatingQuasar]

You mean the high prices of the 68060EC from America?

 :-)

That guy is an absolute morron. I have seen a lot of idiotic and morronic prices on second hand computer hardware as of late. Especially since this euro thing.

There is actually a guy in the Netherlands which asks 140 euro for a plain C64 with 1541 diskdrive. Nuts.

[Effy]

You mean THIS C64  :-? Indeed a bit out of my league  :lol:

The 68EC060 that I bought was THIS Canadian auction which didn´t seem so expensive, until I asked for cheap not too fast shipping cost and got a bill of 45 USD for shipping :boohoo:

[Boot_WB]

Yikes!!  $45 for shipping a cpu is a bit pricey, I'd expect him to wrap it pretty damn well for that.
I bought a full MC68060RC50 from amigakit around 2 months back - cost £50, but mask was 71E41J.  It was advertised on the website as an XC68060RC50, but when it came it was the cooler running MC version - Amigakit wins another loyal customer!

Runs very nicely at 66MHz just with a fan - gets warm without the fan, but has never crashed on me even uncooled.  Haven't yet got any thermal glue to put a heatsink on it.  Runs very nicely on my BPPC since I replaced the 040.

As for the EC version I tried - ran most things perfectly well, but anything compiled for 060 was an instant crash - including Ibrowse060 and (iirc) PPaint.

[amigakit]

Still got some 71E41J MC versions left plus some 66Mhz and 75Mhz 68060s (EC).
