HD6950 modded SLOWER than stock HD6950

Hi!

Today I was modding my Powercolor HD6950 to HD6970. Every step like w1zzard said. I've updated powercolors bios for powercolors 6970. Everything is fine, more shaders (1408 to 1536) no artifacst, low temps etc. Except the performance Stock HD6950 is 4 times better than updated card oO. Modded HD6950 is worse than GF450.

My specs:
Intel Core 2 Quad Q8300 2.5Ghz @ 3.37 Ghz
2x2 GB DDR2 800Mhz @ 900Mhz
Asus P5B (newest BIOS 2104)
Corsair TX650

Im giving you 3 attached screenshot from unigine heaven benchmark in htmls report style. Can you help me to find the solution of problem?



Greetings.

I have a feeling your 6950 has the slower memory on it and it's throttling performance. If you haven't, try reinstalling your drivers to see if it helps.

Welcome to the forums po1nt! It's a shame your 6950 isn't running 'full speed'. Have you tried a different manufacturer's BIOS just to see if that changes anything?

I was planning on purchasing a PowerColour card tonight as well. Looks like I'll be paying a few quid more and getting an XFX.

What does GPU-Z report?

most likely your gpus memory cant support those speeds try lowering the memory speed to 6950s default 1250 and see what happens if that dosent work then just flip the damn switch for the backup bios and presto your back to 6950 regular performance and just overclock the friggin thing as overclocked via catalyst the 6950 matches a stock 6970

It's odd. After clearing CMOS it's 16x but when im overclocking cpu it's changing for 1x. What option in bios may cause that effect huh?

just normal thinking, when i saw GPU-Z said PCI-E x16 @ x1 but i hope that will work, bcs i doubt it the bios flash gone wrong but still can also just be a bad bios for ur card.

Without knowing for sure, why not start OC'ing one step at a time and see exactly when it changes. You'll find your answer that way if nobody knows from experience.

Make sure you aren't changing the PCIe speed from 100MHz(?), that can cause LOADS of problems.

If that doesn't work try to see if there is some way to force x16 through software, I think Rivatuner can do it, but I don't think Afterburner can (which is odd, because Afterburner uses Rivatuner).

I think the bios usually has an option to force 1x but not sure if it has one for 16x.
Just make sure to manually set the PCI-e clock to 100mhz instead of Auto.

Did you try using a modded 6950 bios (same 6950 with unlocked shaders) instead of using a 6970 bios (different memory timings might be messing you up)

If you haven't, try this:

Control panel--->Power Options-->Change Plan Settings-->Change Advanced Power Settings-->PCI Express-->Link State Power Management-->Off
