Should I push more...

...for a 24/7 rig?



That's my only two test on this build, Intel Burn and 3DMarkVantage.
It averages 51fps in FO3 maxed out, and 47fps in Crysis Warhead
maxed except shaders and texture on medium. I have RivaTuner
pushing my 4870x2 @780/936MHz but feel like this is the area that
needs the attention and not more over clocking on mainboard cpu/ram.
Will pushing the PCI frequency a little help???

Seems very stable but maybe I should do a 24hr prime95. This current
OC may even be too much for a 24/7 and I had better quit here but the
H2O in the entire loop gives me good temps.

You know how it is, always wanting that little extra...

You could try, although personally, I'd be satisfied with the speeds you're running at .

Not with those temps, I wouldn't. Personally, I would back it off as 70c+ is too hot for my blood. Although my machine sometimes runs 100% for days at a time, so it may not matter for your daily use if what you're doing isn't flat out pegging it.

If those are IBT temps then he's fine as nothing will get even close to those temps.

Go for 500x9 as its the sweetspot, should take ~1.4v to do it if your board can handle it

Prime95 will make that load about high 50 low 60s
General use will have that no where near high 50s

As for cooling & testing the CPU @ further VCC, I would use Prime95 to stress so that you don't wear out your CPU & still have good testing (just take longer)
Are those the max clocks that you can get with the card? Should be a bit highre...

max temp on these cores is 100C.. 70C aint all that bad.. especially for running IBT which generally will be about 15-20C higher then running a standard application at full load.. that includes F@H and any other distributed computing application..

nice overclock btw..

Well, like i said, it may not be his daily use pattern to 100% load the cores for hours or days on end. But thinking that no app. will come close to the temps produced by ibt I have to disagree. Judging by the numbers thrown around here anyway. I use prime for testing, & rendering from 3dmax will exceed my prime temps by +10/12c every time. May not be 'as' hot at ibt, but i'm sure it's fairly close, and it will stay loaded there for several days at a time.

I understand that 70c's not close to the max temp, but that doesn't mean it's not harmless to your chip. But again, like I said, it's all down to your particular usage habits & preference wether it's acceptable or not. Was only giving my opinion based on my own circumstances/preferences.

Actually, it is essentially harmless. Obviously there is some minor added wear due to the higher temperature, but it is well within spec and will not decrease the lifespan of the CPU by any significant amount.

So on a 6600, what do you think would be acceptable around the 1.55v area? High 60's always just felt like the general limit of my comfort level (personal preference ofc.).

1.55V wouldn't be acceptable to me altogether, since that is at the absolute maximum voltage specified for the CPU, which could be harmful. However, I generally like to stay between 15C and 20C from Tjmax for long-term operation.

Thanks guys for all the feed back, really! I have decided to stay put on the oc.
I will though pull my Apogee block and use an after market tim (mx-2) and
put higher rpm fans on my quad rad to help out with lowering temps. I have
very low rpm fans on them now for noise purposes which could have been
achieved with a speed control set-up and high rpm fans. Hind sight 20/20.

Now my gpu is a different story. I think there's room for improvement there.

Thanks again! -keith
