hardware dilema for my folding rigs

The Powerstream 520W is one of the few OCZ PSUs I would actually be comfortable using for a situation like that. It is a pretty good older Topower unit. Not very efficient, but it is capable.

4ghz on stock voltage? Hot damn!

I tought he meant he left it on auto. 4 ghz on stock and stable is almost impossible.

What I meant is that I didn't raise the Vcore (motherboard is EVGA classified) Right now if I look at CPU-Z it's 1.294V @ 4 ghz. Didn't really tried for more, because 75C core temp is enough I think.

That's pretty good. EVGA's boards do have a habit of really counteracting VDroop with adding a bit more voltage under load. Still good.

You will lose more PPD running 7 cores and using Bill's process manager to allocate all your GPU clients to one core (core 7 if numbering from 0 to 7).

I have an i7 920 @ 4.0ghz as well folding BigAdv with three GPUs on it, and TPF (time per frames)went up by about 1.5 minutes vs. no GPUs. I only use WinAFC to set them to "normal" priority, and not allocate them to a certain core. When I tried -smp 7 my TPF went up by about 4 minutes, which means a lot less bonus. Either way the GPU clients didn't seem to lose anything in terms of performance.

Try it with -smp 8 and no process management, and then go from there. The VMWare Player runs under normal priority, and the GPU clients under low, which means they shouldn't interfere much with it.

It's finally up and running fine for 12 hours now on my core i7 rig. Really fine! On the same protein, my PPD dropped 1500-200 ppd... not bad at all! Found out that I need to start up VMware first and then the gpu. When I was doing the gpu first, the VMware bigadv folding client was giving an instable machine error.

I'm running now @ 36 000 ppd just for the core I7 rig.. not bad at all!

36K is pretty good, but it should not matter at all what order you run the clients. I would worry about instability still...

Don't know why it's like that, because my I7 is folding since last wednesday without stability issue, that problem mentionned appeared the only time I started the gpu's before the I7... and also before starting folding, I did some 20+ hours of prime 95 stress test (8 process).

eek !!

The thermal specification for the i7 920 is ~ 68 C.

Thats waaaaaay too hot bud.You are hurting your processor.

[Charloz24]

That is Core temp reading... I am 20C below TJ Max (98C) I tought it was ok...
