wierd temps when ocing crossfire 6870's?

post #1 of 10
Thread Starter 
so im overclocking my XFX 6870 to 910 MHz(10 from stock) and i go and test it with furmark 1.9.1 in fullscreen.

i see that both my gpu's are reaching temps of 75 C, this has never happened before at such low overclock for me. i have overclocked my XFX to 970 MHz before temps started going towards 70 C (this was before i had a crossfire setup).

does anyone have any idea whats going on? i purchased a longer crossfire bridge since i have 3 pcie express slots in my mobo, im hoping that the extra room will alleviate some heat.

also, on my XFX 6870, i have an aftermarket coolero n it, yet it still reached a pretty high temp at such a small overclock.

its 17 C, 62 F where i live right now, though its a bit colder since i have the room fan and a fan pointed right at my computer case.

im just worried since ive never had that kind of temperature before, is it normal?

anything sub 90c is fine, tbh if my single card ran at 75c i'd be happy.

ok, at least i wouldnt have to worry about that.

thanks for the help, would having the cards one pcie slot farther help with temps though?

+rep for soothing my fears ^^

Um,

tbh with that card, they run pretty cool already, you might have an increase of 3c -4c

Not 100% sure though.

Comps is pretty bang on, my cards run 73c top 68c bottom(amb 20 C) OCed 990/1205 which is a little higher than yours, but I have a HAF 932 with an extra 120mm in the bottom.

something weird has been going on with my setup starting just a couple of minutes ago:

when i first tested my 910 MHz in furmark 1.9.1, after a bit it actually restarted my computer after a BSOD, i thought that this was because i had oc'ed my cpu to much so i set my i5 from 4.5 GHz to 4.4 GHz.

then i ran furmark again fro about 10 min at stock settings and it was fine.

JUST NOW, i had tried playing crysis because i hadnt played it after i BSOD so i wanted to know if it would be ok to play a game. turns out, i was loading the game, and turned on full screen in the settings menu, and crysis freezes and crashes with the tray icon telling me: " amd drivers were unresponsive and crashed, but were able to be brought back". well, it basically said that, but i cant quite remember. this usually happens when i oc to much and the card cant take it.

seconds after that, i BSOD again, and i restart my computer. i play crysis again, and after setting the screen to full again, i manage to get into my last save and play as normal.

but im worried about the BSOD, this has happened twice now, would it be because of my cpu overclock or did something go wrong with my gpu?

Have you reset everything back to stock to see if it does it?

Can you give me all the settings for your 4.5Ghz OC on your cpu, also, what was the BSOD message?

Your guys card temps seem really high to me. Im running 2 6970's clocked at 940 core and 1450 mem clocks and only get up to 63c when benching on 3D mark. I dont have any aftermarket cooling on them, just the reference induction fan.

Also, your driver crashed could be caused by the new amd video drivers. Mine seem to do it more frequently now. I have rolled back to 11.8 since BF3 beta is gone.
