post #15021 of 38704
Just to add to the VRM stuff, 85c is a good long term max. I have no cooling on my VRM's and they hit 100c in every game, so I added a 120mm fan to blow side on, between the cards (at the end of the cards) and it kept the temps to 80c. Plus, I use vsync, so the VRM's are around 70-75c when overclocked and slightly overvolted.

Is it better to oc with Afterburner/trixx than with the CCC's Overdrive? Asking because I have OD limits of 1500mhz for core and 1950 for mem.

I'm having wierd VRM issues also. VRM1 hit 100C+ in BF3 (79C idle), but VRM2 sits at 27C all the time. Not sure what to make of that

There are my favourites...I want the less noise posible and cooling efficency / overclock.
The cards are about same price in locar sellers.
7950 POWERCOLOR PCS+
7950 HIS ICEQ TURBO
7950 GIGABYTE WINDFORCE 3
7950 SAPPHIRE OC EDITION

It´s very difficult to me choose one, please help me...Which is the best/quietest and cooler of four?
Sorry for my english!!! and thanks.


Hi...thanks...

Probably I´ll go for the Gigabyte Windoforce 3 .

I sold me about 290€ ...

One mor question?.

Do you think that THE HIS 7970 ICEQ2 TURBO is really worth for 130€ more ---> 420€

Thank you!!.

I'd say quite a bit.. It'll be better then your 5750 though. You might want to try unlocking the Phenom II 550 though, if you can get a tri/quad the bottleneck would be less thumb.gif
Otherwise I'd suggest upgrading to a 955BE or a 960t thumb.gif

EDIT: Can't seem to get VRM temps to read properly.. GPU-Z and HWID (or whatever the program is in the OP) tells me 24c idle and under load? rolleyes.gif
You never will be able to read your vrm temps with software, with your current 7950. We can thank the factory(s) that made the reference 7950 pcb's for that.rolleyes.gif
My VisionTek 7950 is the same, the reading with HWInfo 64 is stuck at 25C, never changes. Although the card appears to have the same CHIL CHL8228 chip that works with the 7970's, it is non-functional on the reference 7950's. The 7970's do not have this issue, nor do the 7950's that have a 7970 pcb, such as those from MSI and Sapphire.

Don't know what you are talking about, I have Sapphire HD7950 first edition OC Edition, (2nd BIOS @ 900Mhz), and GPU-Z reads my VRM temps fine...
