Sorry if it has been posted but there's a new Afterborner out
http://downloads.guru3d.com/Afterbur...load-2604.html
Don’t know if it was just me but with Beta 6 I had problems with profiles & power play.... they work great now & my card now idles low 30's. I fully removed the old version with settings before working out they have changed the way you edit the .cfg file to make things work properly :D read the notes at the bottom of the page.
Sapphire 6950 flashed with Sapphire 6970 BIOS, reference board and cooler.
6970 stock GPU Volts - 1000/1450
http://www.framebuffer.com.br/sites/...-1000-1450.JPG
http://www.framebuffer.com.br/sites/...-1000-1450.JPG
Overvolted to 1.3V with MSI AB - 1050/1450
http://www.framebuffer.com.br/sites/...7299-11-1a.JPG
Are there still no unlocked BIOSes with higher overdrive and voltage limits?
Sorry if this is a bit off-topic...
I'm looking to upgrade to a 6950. Is there a difference between Sapphire or HIS? Can I use any of the 6970 BIOSes for both of those reference cards?
Seems my Gigabyte 6950 can unlock without a problem
It doesn't matter, as long as card has reference design.Quote:

You can tweak these voltages with RBE or just unlock your own BIOS. I don't see a problem...
you can actually manually unlock the shaders using your own card's bios?Quote:

XFX 6950 1Gb XXX sell in Italy for 200-210 euro vat included (20-30 euro under reference 2Gb).
But I dont think you can use the regular bios from the 6970 2GB versions with a card that only has 1GB worth of chips on it. You would need a 6970 bios made for 1GB of vram, which there isnt one. So the two models aren't really the same.
Go here:

and scroll down to Test Results section for success and failure rates.
Are you quoting me?Quote:

There isn't B plan ;)
So as of yet there's no soft way of increasing the memory volts on these cards? (The VTT regs button in RBE is blanked out)
How about increasing the overdrive limits on a 6950 bios? That way you can keep voltage adjustment in AB, clock past 840 without disabling idle downclocking, and keep all the 6950 memory settings.
I tried using RBE to put the OD signature from a 6970 into a 6950 BIOS, had to force flash it, and then Catalyst didn't detect my card. No big deal with the BIOS switch and all, but no success either. Anyone else have any bright ideas?
If you change the sig you have to re install the video drivers. Rbe warns you about itQuote:

Either way, I'll give it another go and report back. It'd be nice to have voltage adjustment, unlocked shaders and idle downclocking all working.
It all work fine using wizards 6950 shader unlock & afterburner.Quote:

Sure they all work, but not if you want more than 840MHz core. Then you have to enable unofficial overclocking in AB, which is apparently incompatible with the idle downclocking feature in Catalyst.Quote:

Quite a few people who unlock their 6970 get small artifact errors due to the memory timings being different on the 6970 bios compared to the 6950.Quote:

Interesting, so the memory chips used are actually different between the two cards?Quote:

OR
Are you saying that the 6950 keeps its memory timings and when the 6970 clocks are applied it gets slightly buggy?
I'm assuming there is no way to alter the memory timings manually...
i havent had any trouble with my flash but im using 6970 bios and memory is at 1450 no issues..stock volts. so maybe for some it's an issue and others it isn't. Diamond card here.
The memory chips are binned different on the two cards, some peoples cards have issues running the higher speeds and tighter timings of the 6970 bios. It's all a little hit and miss like with any overclocking.Quote:

Just got my HIS 6950.
Which 6970 BIOS should I flash to? Do I need to use the HIS 6970 bios? If not, is a particular BIOS preferred?
Doesn't matter as long as it is a reference card BIOS. You can choose from the stock 6970 BIOS or use the 6950 BIOS with unlocked shaders with the tool available from Techpowerup.Quote:

My memory is pretty good clocking though alot of 6950 wont do 1375 or higher it seems.
Your card is pretty much identical to mine.
I was running 950/1450 the other day with 1.18v, thinking it was stable. But i was playing half life 2 with 8xaa 16xaf and about an hour into play it grey screened on me... which always used to happen if i took the memory over 1500. But now at 1450? :( could be because of the high memory usage due to the high aa and af i was running. I'll just keep it at a nice and cool 900/1400 with 1.10v, have had no problems what so ever in all the hours i've played at that clock.
My mem seems to be happy at 1400 or so, I dont really see a benefit at even much over 1250 tbh, my core needs 1.2 for 950.
Many thanks. I'll give it a try.Quote:

Good point, i may have to bump the core to 950 then while i leave the mem at 1400. What temps do u get at 900 and 950? and at what fan speed etc. I've got quite an aggressive fan table set in trixx, keeps temps under 65c with around 50% speed at that point. I don't want it to go over 70c as these are really sensitive to temperature in terms of voltage needed.Quote:

Ahh cool. Yeah i gave my whole system a thorough clean the other day. My cpu heatsink was clogged to hell with dust as well as around the vrm area on my motherboard, has dramatically lowered temps. I also was brave enough to open up my PSU which was ungodly, it hasn't seen the light of day since i got it about 4 years ago :p: mega peace of mind now. As for the GPU, i just stuck the dyson at the vents and the fan, didn't do much in terms of temps, didn't expect it to really. Hasn't been long enough yet to the point where i'm brave enough to apply new paste or of the sort.
My card idles at 49C @ 25% fan speed. Is this too high? I haven't set up any fan profiles yet.
It sounds a tad high, mine idles at 30-35c depending on the ambient, at 25% as well. I can imagine it going up to 40c in summer though (yet to experience summer with this card).
You're not running dual monitors or anything are u? Idle clocks and voltage should be 250/150 and 0.9v just for reference.
yeah I idle in the mid 30's at 20% fan
Running a single 30" @ 2560x1600. Idle clocks are 250/150 and 0.9v although they frequently get bumped up to 500/1250 while watching YouTube videos or movings.Quote:

Am running Trixx for FAN profile, 40c idle / 75c load.
Also 20% extra power thru the CCC.
HIS non reference 2GB card, unlocked shaders seems OK.

VRAM is pretty o'cable too on this HIS card.
It seems that there is a golden batch of week 50 Hynix GDDR5 VRAM which can perform up to 1600 MHz floating around on certain HD 69xx cards... so I quickly referred back and rechecked my photos on the HIS card. Oh well, this card has the earlier week 47 batch but never mind, let's do some pushing and see how far it can climb nonetheless.
Keeping the core at 900 MHz, I started pushing the RAM from 1400 MHz and compared 3D11 scores while eyeballing that there are no visual artefacts during the runs. Looks like the current batch of cards with week 47 RAM isn't too bad either.

I just ran 3DMark 11 (performance) with and without the power control option.
Unlocked 6950 (stock clocks):
Without - 5021
+10% PC - 5012
Seems to be no impact from the power control option in Overdrive, at least in the synthetic benchmarks. Maybe I'm doing something wrong?
Interesting. I'm using the very top PCIe slot, nearest to the northbridge and CPU heatsink. Maybe some heat is dissipating from there, causing the card to idle at ~50C.Quote:

@mac im glad you brought that up because like you i thought my vram would overclock higher so i went ahead and clocked mine and it benches at 1550 as well but 1500mhz is good for gaming..but this also made me try to attempt to overclock my gpu further and happy to say i got 1000/1500 stable gaming stock cooler with 1.275v very happy with my $235 6950 ;)
Is it easy to check the batch on the memory? I would love to check mine out but I have never tinkered with my VC's before so any advice would be great.Quote:

Hey guys, quick question here: Are you folks still having success flashing 6950s to 6970s? I ask because I can get a pair of Gigabyte HD6950 2GB cards for pretty cheap and was wondering if they are still unlocking?
They should, unless they are non-reference ones.
Noob question, but when you say "reference" one, you mean one with the basic PCB right ? Is there a method to check if a card has it, except by looking at the pictures taken by the seller ?
yeah usually you just have to eyeball the pcb and coolerQuote:

A little update on my HD6950 flashed to HD6970 via Bios.
SB 2600K cooled by my Blue Cascade @-85c , 5500Mhz.
HD6950 cooled by water chiller @-21c , 1.42v. via smart doctor for 1100/1547Mhz.

That guide is good,however makes me wonder if my sample of 6970 will make more than does currently,1060 on 1.3V,stock cooling and 20+ ambient,no modifications :D
Btw, about the voltages from the guide...
Quote:
VDDC: GPU Voltage
MVDDC: Memory Core Logic Voltage
MVDDQ: Memory Voltage supplied to the output buffers of the video card memory.
Seems correct to me.Quote:
(correct me if I’m wrong) VDDCI is the I/O bus voltage (between memory and GPU core) and comes from the PCI-Express slot.
Apparently the guide is aiming for
These are the defaults (vGPU is quite obvious, though).Quote:
1733 mV VDDC, 1725 mV MVDD, 1965 mV MVDDQ, and 1333 mV VDDCI
1.73 vGPU is quite nuts, lol. +0.3V MVVDQ is also tons, no? At least for anything remotely close to a daily rig... +0.05V vDDR seems fine. +0.078V VDDCI seems reasonable, too.Quote:
Under 3D load, on our Radeon HD 6970 sample, the Graphics Processing Unit (GPU) VDDC measured 1252 mV. The GDDR5 MVDD measured 1674 mV, and MVDDQ measured 1667 mV. VDDCI measured 1255 mV. All measurements made were referenced to the PCIe input power connector ground.
Yeah but thats a HD6970 :yepp: , we are talking about HD6950 here , its a good overclock for your HD6970 none the less :). But regarding HD6950 its a diferent story.Quote:

my 6950 flashed fine to 6970 bios and runs 24/7 at 1000core 1500mem at 1.3v..maybe more in the core clock but havent tried over 1000 yet just enjoying it :) before i could bench 950core at stock volts however wouldnt last in black ops for more then 15-20 mins.
i might give 1050 a go and see if i can push out a vantage or something
