Plugging CUmine in unsupported board?

[Godfodda]

What would happen if one were to plug in a Coppermine CPU in a board that didn't support the voltage level required? Anyone done this?

I've flashed my old POS board with the latest BIOS, but due to the total lack of support and documentation on the website I have no idea how far they've come with their revisions. The only difference I can see is that the multipliers now run up to 16. There are no OC options on this thing, but if it'll take the Coppermine I'd of course be happy to throw in a Celly2 to boost the speed. The only way I can think of to test it is to actually stick one in and see what happens. Anyoone have any ideas?

The differences in voltages between the coppermine chips isn't so great I'd fear too much bad occurring from doing this... if it's a really old board you run the risk of the higher voltages as default...

I guess you answered your own question, plug it in and see :).

BTW, what's the make/model of the board in question?

It's my old PCChips M748LMRT (slot 1 *and* socket 370). Been searching slotket reviews lately and noticed the updated BIOS revision. It's only a SETI machine, but faster is better there of course. :)

Funny, there's another thread (http://forums.overclockers.ws/vb/showthread.php?s=&threadid=48233) dealing with what might be the same issue... the changes between the cB0 stepping and cC0 stepping cpus... check towards the end of the thread.

Thanks for the note. I guess I need to start reading EVERYTHING again instead of skimming.

FYI, I tried it. Didn't work. I may have screwed up though. When I put the old Celly back in, it wouldn't restart. Thought I'd screwed something on the motherboard. After a few minutes of swearing I happened to notice that the locking arm was still raised. :rolleyes: What a moron. I may have done that when I dropped the CUmine into it also. Don't know. And I don't have the b*lls to try it again tonight. :)

aw c'mon.. Maybe you had the arm up when u stuck the cumine on.. its worth a try.. :)

DON'T FREAKING TRY IT!!! I REPEAT.....DON'T F$$^$ING TRY IT!!!!!!
Just yesterday, when accidently dropped a p3 800e into an intel mobo supports only ppga, guess what? Both of them ceased functioning!! no vital sign of any kind!!! and worse of all, the chip isn't mine!!!! *****..now i have to get him a new 800e.....:eek:

Yes it should work. Those m/b that can't support the coppermine voltages can supply 1.8V min. Use a socket PIII & a slotket. Set the voltage to 1.8V on the slotket & fit in the slot. A cC0 needs 1.7V & a cD0 takes 1.75V so the extra voltage is nothing. I successfully upgraded my ms-6119 with a PIII 800 in this way. You have to have a bios that supports the coppermine though.
