Sounds like it's time to open that Phenom II. Ever thought about overclocking?
So tempted to get a 7950. Is getting a boost model much better than the originals?
Hi,
Ive got 2 Powercolor 7950s running in Crossfire mode.
The primary card is a V2 card while the secondary is a V1 card.
The primary card is brand new and, under load, runs at about 92C.
The secondary card runs at about 70C.
Does anyone else have this problem ??
The V2 primary card is brand new. Is this normal operation for a 7950 ??
Thanks
the card on top tends to be hotter.
Thoughts:
The recent purchase of the (2) HD 7950 sapphires at $425 was hard to pass up and a deal of a life time (compared the the $349 on 850pe agp long time ago lol!). So without any hesitation I made the purchase and installed it in my system, and they worked wonderfully with the 650W corsair psu in my pc. It ran without any hiccups, and installation was pretty easy despite it being larger than the HD 6850s I had before (They served me well!). And right off the bat...the performance is twice as fast than before, and to me it's pretty mind boggling. My CPU right now does no justice, but it's decent enough to play the games today, especially the eye candy. So here are my results !

I think you should have purchased one 7950 and used the money you spent on the 2nd one to upgrade to a 3570K and a Z77 mobo. That Phenom II is a serious botteneck for two 7950's. Even my Phenom II @ 4.0Ghz is bottle-necking my single 7950. But if your happy with what you have now, well that's all that matters.
I'm building a system with a couple of the TFIIIs in xfire. I am unable to use the workaround to get MSI Afterburner to overclock.
I downgraded from 2.2.4 to 2.2.3 and was temporarily able to use the cfg edit to adjust my speeds. However, once the system crashed I have since been unable to change the speeds again. I've tried enabling and disabling overdrive in CCC, as well as deleting the CCC but I still am stuck.
Anyone have similar problems?
Did you try the Asus GPUtweak + MSI Afterburner work around? Read the first post in the thread.
