Then i re installed many differents drivers (12.4, 12.7 beta) each time cleaning with ATIman uninstaller.
Now i got a bsod or a corrupted screen (1 is hooked by now) with red dots and lines.
It always end in a hard reset.
The fact is that if i start my OS in safe mode there is no dispay corruption and of course no hardware acceleration.
I tried also one driver with only display driver but the result is the same.
Obviously it's a driver problem as i managed after the very first installation to run a crysis bench for 30 mins.
I just can't figure what exactly the cause is and what could help to solve that problem.
If any one had such issues and could help ...
My rig
Core I5 2500K @ stock
PSU Master cooler silent pro gold 800 W
Windows 7 64 bits
Gigabyte Z68 XP UD3 with UEFI BIOS
8 GB of RAM (2 sticks)

Im actually looking into an H60/40 Mod of my 7950OC, or buy a cheaper reference one to mod.

as in the summer time, the only thing on my system that even gets close to over heating is the GPU.

- Remove Shroud/HeatSink.
- Mount H60/40 Water Block
- Mount Heatsinks to Ram and VRM using same airflow pattern (air in one end of the card, exhaust out the other).
- If I Can, re-mount the shroud part of the cooling system over top of the water block, and use the Fan to force air through the shroud and heatsinks for the Ram and VRMs

- If I cant Remount the shroud, mount the VRM/Ram heatsinks at the same angle,
fabricate a open ended shroud, put a fan on one end and the exhaust end will be raised to 3 slots, to provide less airflow resistance.

add me to the club. just got my sapphire 7950 and I'm loving it so far. not bad for something I ordered yesterday. here are my heaven runs:
HD7950 heaven runs (Click to show)
out of box settings (950mhz/1250mhz)

1025mhz core

1025mhz core/1350mhz memory

1100mhz core/1350mhz memory

here's my best gtx670 run on my DC2T: gtx670 heaven run (Click to show)
1268mhz core/+100 memory offset

so far so good. max temp in heaven is 62c and the card is running stock voltage (1.093mv) so there's likely more room to go. I can't seem to go above 1100mhz core in afterburner or of course AMD overdrive. going to try some Metro 2033 and BF3, then maybe try sapphire trixx for overclocking. no coil whine at all.


edit: ran BF3, Dirt 3, Metro 2033. didn't record BF3 or metro, but BF3 is about 9fps lower than my 670 was but runs more stable. Metro is about 17fps faster than my 670 at max settings. Dirt 3 1920x1080 Ultra settings 8xMSAA:
Sapphire 7950 1100/1350mhz


Asus gtx670 DC2 Top 1280/1602mhz

Anyone got a hold of a Sapphire Toxic card yet. I've got a chance to order 2 for a Crossfire setup here and I'm rather tempted.

My Radeon HD 7950 @ 1150/1550 does about P9150 in 3DMark '11.

Gets 37.1k GPU score in 3DMark vantage.

The idiots over at EVGA forums think that even a GTX 670 is a better card then even the HD 7970....

well it's a lot faster in 3dmark11 unless you can hit 1300mhz on a 7900. my 670 did P9469 with a graphics score of 9965. if they want to go by only heaven and 3dmark11 then they have a point, but if actual game performance matters to anyone, things look pretty even all across the board.

Nice . 1100 Mhz at stock voltage. thats what I heard about the sapphire HD 7950 950 Mhz edition. You could easily push to 1150 with slight voltage increase and keep temps around 70c.. IMO HD 7950 (1150) wins more games against GTX 670 (1250) and is generally faster. If you have any other games please post the comparisons.

people will have their own opinions. But anybody who has done his homework knows the HD 7950 is an amazing card for its price . thumb.gif
