Any tips on a PD940 (New Build)

post #1 of 35
Thread Starter 
So I finally got this thing out of the boxes and off the floor. So I've started OC'ing.

I've pushed the FSB up to 875MHz and the CPU core up to 3.5GHz, I've got idle temps at 27ºC and load temps at 43ºC. Vcore is 1.2875V if you believe what nMonitor says speedfan says it's 1.25V, RAM is linked and is at 583MHz on 533MHz stock. How far can I push this thing before it starts to crunch, I mean I'm up 0.3GHz and haven't seen too much struggle to this point.

OC it as high as you can go until your load temps go over 58-60C, then stop lol.

That's pretty much the gist of it.. keep raising vcore if you run into a wall, and if your ram is holding you back put it on a divider, but most of all, just keep pushing!

You should get 4Ghz without breaking a sweat at this rate!

EDIT: You will have to put that ram on a divider soon, just realized it's 533 :-\\

If you can, just run 4:3 FSB: DRAM... or a similar ratio.

Put your ram on 5:4 and put 1.35vCore and see where that gets you

How far can the RAM go you think?

Even at 3:2 or 5:4 it's up over 600MHz, I unlinked it, set it at 600MHz and I've pushed the FSB and CPU up to 950MHz and 3.8GHz respectively, still have very comfortable operating temps both at load and at idle.

You work with what you have, right now I have a D 940, someday later I'll move up to something nicer, just not right now, this is a first build, there is alot of learning to do first, no sense in wrecking a good CPU while I'm learning.

Update:

Load temps at 46ºC
Idle temps at 30ºC

FSB at 1000MHz
CPU at 4GHz

and I still haven't touched the Vcore yet.

Mem is locked at 600MHz (the weak link in my system right now, I'm thinking of going with a set of these...

Pentium D series are not decent overclockers IMAO, e21xx, e4xxx and e6xxx are much better in price/performance terms . I don't think you can learn much from an old processor, but that's my opinion, who AM I to tell you what to do

Can anyone tell me why CPU-Z keeps switching the multiplier between 12x and 16x on the Processor?

Time to dive into your bios and disable C1E and EIST. Should be in "JumperFree" or some other settings (not too familiar with the 680i boards).

That solved the problem.

So I'm pretty comfortable with the CPU OC at this point, I'm going to run stability overnight tonight, just to make sure everything is A-OK, but 4GHz doesn't seem to bad to me.
