How to enable additional shaders on Radeon HD 6950

[fullinfusion]

So you're running the 6970 bios OC'd to 990/1450?!!! On stock 1.175 voltage? Man I need to get rid of my XFX and get an HIS! those are some crazy numbers. I'm jealous, well done.

Shit, just looking at some stuff here and yes I was running the 6970 Sapphire bios.
I need to pay better attention and doucument my tests a little closer.

Sorry If I miss lead ya but I only ran one run in fear of hurting the memory and instead Im NOW using the 6950 modded bios for the unlocked shaders only..

Sorry

That makes more sense, the memory doesn't seem to need the extra juice anyway so no need for a 6970 bios. What vcore did you need for 990?

I believe it was set @ 1200v 1.2v in afterburner

I'll run it all again this weekend to be sure and post my results.

That's a pretty awesome OC, especially for the voltage. I may need to give MSI AB another go. When I was using it before, I couldn't get past 930@1.2v. I'm going to give it another shot, using the new beta 7 AB and see what I can manage.

 

[DJManiac]

Can I ask what voltages you are using, core and mem, and did you use RBE to set them? I'd like to bump my core up to 1000 and see what temps I can maintain with my cooler.

Cheers.

Arg... Missed it to gave the Info in my first post

I'am now 24/7 1000/1500 XFX 6950 @ ASUS 6970 @ 1350 mV twitch @ Arctic Cooling Accelero Xtreme 5870 (modded) - max 65°C (only Furmark full load) @ 80-90% FAN (still whisper-quiet)
In Gaming/Benching cold 55°C @ 50% FAN (can not hear the FAN)

btw: in 2D (250/150) I can turn the FAN completly OFF (under 10% FAN in AB the FAN stands still) and have only 43°C - So in 2D passive cooling

Roomtemp was around 24°C

Fully stable with Furmark (all 3 option on) (30mins), Kombustor (30mis DX11 and OpenGL3), 3DMark11 (benching and Demoloop 30min) and Gaming (min. 3 hours straight)

@ 1300mV it is also Gaming and Bench stable but Furmark didnt made it...

mV set in RBE and FAN curve with new Afterburner Beta 7 (Juhu Powerplay and OC work together)

Hey, what memory chips did your XFX come with? The normal 6950 ones, or the faster 6970 memory chips?

 

[shea1980]

So i have just bought a hd6950

Will i be able to unlock it to a 6970?thanks

Wrote it here already: How to enable additional shaders on Radeon HD 695...

T2C -> seams to be "normal" 6950er

Probably NOT! Because of the red custom PCB !!!!

Only the most of the original ATI PCBs (black) are able to do it...

But those custom PCBs are still not well known... Think nobody can say it for sure!

 

[nitoxys]

So... I bought one of the XFX 6950 1GB cards and flashed it to the XFX 6970 Bios, and of course it didn't work. I had to at least give it a shot. Should I try the stock bios for the 6970? I looked at the bios through RBE and there is no way to modify the amount of RAM. This card looks like it's a reference 6950 with less RAM.

 

[nitoxys]

Yup, I have a CM Storm Scout and I didn't check if the card would fit into the case. Then when i tried it didn't. So i had to take my hard drive cage out and the bottom of my 3.5" drive bays, wells its abit altered .

Looking on buying a 600T/700D in the coming weeks, so the CM is fine for the moment.

What do you mean? Fits just fine... I have the same case as you do.

You should return it for a 2gb 6950. Price difference isn't too much.

i have a question maybe someone can answer:

we all know how to enable additional shaders but how to enable additional texture memory units 96 vs 88 (tmus -) using 6950 bios ? if u r using 6970 bios u have all enabled but if u r using 6950 modded bios u have them locked like shaders :/ i figured it out by 3dmark vantage texture fill test, and perlin noise test

same clocks:

6970 bios: http://3dmark.com/3dmv/2889427
6950 bios: http://3dmark.com/3dmv/2896634

score is the same but look at tests texture fill, and perlin noise

and im posting about that 3rd time with no reaction, is this really not that interesting ? ;p

 

[coldrazor]

I have the same case, it fits, but only if the motherboard have the pci-e slot in the first back slot of the case, if not, they don`t fit.

 

[manofthem]

So let me throw down a little something:
Playing Black Ops campaign just now, right about an hour when my pc locks up, had to reset. So I check my GPU-Z log, and it was at 56*C/58% fan when it locked up. 950/1435@1.25v modded bios. I've passed 3DMark11 and Furmark tests.

Any ideas why it happened? Not over heating... Maybe just too much OC?

 

[danc]

The only use for Furmark IMHO is to test how your case ventilation of heat. Furmark cannot tell stability of modern 3D gaming.

3DMark11 is not good stability test too in Performance settings. Try testing with FF14 benchmark. If total bad OC, it will lock up immediately in scene 3 or later - the ship parts. If not very stable, it will crash after 2-3 loops. Just use 720p settings and let it loop in background while your surf TPU.

Gracias for the tip. I'll check it out tomorrow and see what's going on with my OC.

 

[remdiablo]

Sorry guys,may be I missing something ,but, I used a W1zzard tutorial For unlocking shaders and clocks.So my Q is- Why Voltage is not working in MSI AB,no matter if I increase V or put it down, Furmark shows the Same 1.175 V.Any idea???? may be I need just flash it to 6970 bios, to take effect? Cos at stock everything works fine, modded I lost Voltage control and can't pass CCC limit even if I enable unofficial overclocking .930/1400 this is highest I 've got stable,without Voltage increase for CF.Need advise please, GURU HELP PLEASE.

This is strange. I thought that everything is unlocked. Can you PM wizzard with this question and see what he will say about this.
P.S. as for the GPU-Z it shows that texture fill rate and pixel fill rate are equal to 6970s at the same freq.

Make PT to +10% to your 6950 mod. The texture fill will become same scores.
Color fill seem to lose out 0.1~0.2 to real 6970 with no effect from PT.
PT +20% seems only increase perlin noise scores but cannot reach 6970 levels of ~190.
So just leave PT +10% for 6950 mod is optimal?

A good reference for view.
http://techreport.com/articles.x/20126/6

I think this will make interesting research to unlocking. Do we need to use unlock bios to activate all TMU? Or increase PT will be enough? It seem 6950 shader mod bios, the card is still different from real 6970 or even 6970 bios flash. Perhaps in the communication of power delivery by respective bios?

I have not the time to test. I hope some else can do.

Tried searching all the pages in here and didn't find any information about artifacts. But, I seem to be getting some, however only noticeable in WoW (ran 3DMark 11, Bad Company 2, and WoW). Turning of Vsync in world of warcraft helped a lot, but when I came across a fire zone I saw artifacts again. Previously it was on a lot of objects including the sky and windows, but vsync off fixed all that. See attached image and link to video so you can see my temps, speeds, voltage, and in the video the artifacts i'm talking about. Yes flashing back to 6950 fixes it, dropping clocks does not fix it on the Sapphire 6970 bios (the one im using), tried bumping voltages up by .05 from 1.15 up to 2.15 then stopped as i didn't want to go too high. Any ideas? Where is this 6950 modded bios everyone is talking about?

The video isn't good quality, but just watch and you will see the flickering, it's very noticeable, especially the large fullscreen flicker near the end.

edit: also PT is at +20% fyi
edit2: should note it only artifacts in this zone using large amounts of fire, no where else that I have noticed yet. But, again, flashing back to 6950 original bios solves it. Hmm, bad card?

 

[arroyo]

One offtopic question gentlemans:

Do you know, if it's possible to remove the vapor chamber from HD6950 cooler without removing the metal base of the cooler? I want to apply Accelero S1 on my GPU and I want to have stock cooled VRM and memory. At the backside of the cooler it looks like vapor chamber is attached separately.

You still running stock cooling Manofthem?

56c/58% while in a game seems very low..

my gpus @ 65c/55%fan idle without an OC... only shaders unlocked..

 

[itsdanny]

@Stranger,

Just to add in, I also get temps of 55c average (max) in a game on a custom fan curve that does not exceed 60%. I idle on 35c average. Something must be restricting the airflow within your case.

I used to have similar problem in F1 2010 with 6970 BIOS, it is gone when reverted back to 6950 unlocked shader bios.
I think this is some kind of mem voltage in 6970 bios.
