cpu temps

[38ruk]

That PSU is borderline in my opinion . the 7800 series requires 20 amps on the 12 rail , yours is rated for 16A .

A PSU will overheat when it is being over worked and that will cause a system crash , so the fan blowing into the side of the case is more than likely helping the PSU to stay under the thermal limit .  From the looks of it you soon find out which piece of hardware is causing the issue GL 38

the new heatsink lowered the temps some:
before


after

(might have got away with just cleaning the old one - it was dirty)

I haven't locked up in AH but IL2 FB did. Haven't tried Tiger Woods yet.
but I think you guys are right about the power supply..
thanks for the amperage info 38
I think that is my main problem and have a OCZ ModStream OCZ52012U coming. It has 26amp on 12volts.
Let you know how it goes
thanks again

Good to see ur temps are down alittle bit . I bet the new psu will fix the issue your having , id like to see how it turns out either way. I have an older antec 430W true power laying around here , its a 20A 12+ rail capabile . If you get into a bind PM me , and i'll trade you for your old one , i just need a know good one for a tester .   38

I also have a spare Antec 430W unit.  I pulled it out of a rebuild and there's hardly even dust on it.  I'd be glad to donate it if it will help.  It was free

thanks for the offers, my ps from newegg should be here by the end of the week
I read that the computers now use the 12v rail for the cpu, that before it used the 5v. That makes the amperage critial on borderline setups as mine.
Wonder how many others strange/intermittent ah or other cpu issues are related to it. I noticed my 12v hasn't read above 11.2, closer to 11, since I have started measuring it. maybe another sign that it is struggling.

edit: Tiger Woods froze faster than IL2 FB

WOW i never noticed that in the screen shots above . 10.94v on the 12 rail is really a true sign of a psu givin up . Ive never seen one go that low before .

I installed the new  OCZ modstream ps and all looks great now!
My temps are lower across the board and my voltages are higher and more stable.

I played IL2 FB for about an hour last night as well as Tiger Woods - both at max video settings and both played flawlessly.
This morning I bumped my AH settings back up to 1024 textures on a 1280 x 1024 resolution and flew around fighter town for about 45 minutes without a hiccup. (7 kills in two 109f sorties )

thanks again for the power supply info, it pointed me in the right direction
