@ Cele303

Check pm!

I've done a fast test on 12.4, my card was hot like hell
Sapphire ref. with stock cooler

MetalRacer, how much did you gain with new driver?

Martin, I have tried the Asus BIOS with additional voltage. 1.39 on gpu and 1.7v on RAM. Did not really help.

Stuck at 1330/1950 @ 40C with watercooling.

Have we hit a wall with these cards ? Looking at previous posts I would say yes.

[Martin.v.r]

no graphics errors on the GPU at 1400MHZ, but it just shuts down after a heavy time
but I will not go any longer with my mem, they saw's max

can play b3 whit 1350/1700 max c load 38c


would be nice to be able to edit the vgpu / PLL volts,whit org bios

@martinv.r. what wrong with asus bios?

[emertX]

Watch out for the sapphire oc and the vtx3d...they have 7 instead of 6 phases!

Does anyone know whether the VTX3D HD 7950 X-edition uses a CHIL 8228g vrm controller?

[nascasho]

Whats the concensus on the model of 7970/50 to buy? Looking at all your results it seems that the 1.3V spot is good with good cooling.

[Bestofbritish96]

If i had to choose my cards again, I would go for an MSI Lightning 7970 with EK block, backplate and IO Bracket.

Getting a 7970 which does over 1320/1850 on water is a lottery.

[Hondacity]

Does anyone know whether the VTX3D HD 7950 X-edition uses a CHIL 8228g vrm controller?

its the same, only difference is the complete 6 phase for gpu

[The Jesus]

Been beating on my 2x 7950s with EK blocks for a bit, trying to clear 1275/1850. Highest full run was 1250/1850 @ 16313 3D11Performance. They're pushing 54C :O (although, that's with a 2600K @ 5.0 GHz/1.5V, lmao)

By the way, I have first place for 2x 7950s

EDIT: Full run on 1275/1850 successful! I'll try to squeeze a little more once the cards cool down, lmao.



EDIT2: Pushed harder to 1300/1850! These coils are going to explode, sounds like a fan with something stuck in it

[PatRaceTin]

guys i am in decision between single HD7970 or single GTX680

(VGA Water cooling)

which card should give me more score on 3DMark ? (both card max OC on water)

[gabe]

This just for fun.. see complete post here

[gabe]

And here are the final scores for this particular setup, which is 7970 + 7950 in XFire, with a couple of Komodo's 7900 blocks:

Someone test this on their Tahiti card.
Run the TSMC-PDE_V1.2.exe and post the contents of ASIC_Data.txt file.
