New Bios update for gigabyte HD7950 ! - Page 19

post #181 of 1324
I needed 1.225 to be stable at 1100 on occt 4.3.1 dx10, 480x480, error check on, shaders 7, fps limit 0

powertune should be set to +20 too

this is with any bios for me

Can you provide me with info about this atiflash under dos bios update?

BS was that message. The most Gigabyte WF cards have terrible ASIC quality. Mine can do 1030Mhz BUT my default voltage is extremely high (1.093 ). It's so high because my ASIC quality is terrible, too -62%.

My first WF 7950 had a bit better ASIC 71% with default voltage 1.031V ( which is the norm ). But since my ASIC was still bad, it could only do 950Mhz.

It depends what's your default voltage + ASIC quality mostly. If you have over 70% ASIC, you probably have the normal Voltage ( 1.031 ). The better ASIC, the better default Overclock.

That ASIC quality is BS mate biggrin.gif My WF3 has ASIC 65.1% with default 1.093V and i can easily overclock to 1050/1500 wink.gif

Yes... 1.093, as I said... which is much higher than the 1.031. Ask the people with over 70% what''s their default voltage... They will say 1.031.

The thing now is, if you have around 70%, you are in the limits... You get 1.031V, but of course not a good margin for default OC. I don't see anything being BS about ASIC. Keep in mind, I'm not talking about extreme overclocking -only about default voltage.

Incidentally, if you see a guy with over 85-88% ASIC ( rare thing on AMD 7000 series ), he can probably max out the clocks in Catalyst ( 1100Mhz ) without touching the default, 1.031 Voltage. That's a good card...

Also, do you have too WF? Only 65% ASIC. W1zzard from Techpowerup was absolutely correct when he said Gigabyte is cherry-picking the low ASIC cards.

So because of the asic quality my card isn't good clocker. Mine is 58.4% and it is one of the lowest asics i've ever seen in the net. The voltage is 1.093 as you said. So will the bios update help a little or not?
post #186 of 1324
See? Even lower ASIC and he gets even lower default clocks... So, what we have?


DimQa's: 65% ASIC - 1.093V - 1050Mhz Core
My card: 62% ASIC - 1.093V - 1030Mhz Core
Belkov's: 58% AISC - 1.093V - 985Mhz Core

My previous card: 71% ASIC - 1.031V - 950Mhz Core
A random card I saw on TechP: 88% ASIC - 1.031V - 1100Mhz Core

Tell me what's BS about ASIC...

@Belkov, personally I don't think there is something that can help; it's hardware. Now if a BIOS could fix some hypothetically problematic, related things, that would help us all to climb a bit higher.

ok. Thanks. So i won't boder to update my bios. The card is stable and even without clock it's a powerful vga. after an year i'll buy another card. i think this is the reason that the quality of these cards isn't very good. smile.gif it works for me. smile.gif
post #188 of 1324
I wouldn't say the no 1 problem is the terrible ASIC. At least Gigabyte has extremely good cooling. It's fully quiet and extremely cool card.

The cards are plagued by Memory Latency problems, flickering/corruptions on Dx9 games etc... They said they will improve the code for the memory latency, but what I'm afraid of, is the second problem, the flickering. One year now and there isn't a single fix. Right before Christmas they mentioned a fix while they didn't fix anything... Guess why... So, what if this flickering is caused by problematic hardware? Wouldn't be a reason for recall? Given AMD's bad economic situation, I'd never expect an honest recall.

I already sent my first card back for this reason. Now that I'm pretty sure it's a general issue and additionaly has been confirmed by them, might as well change brand. When I paid 400€ for this card, I was expecting a fully flawless card that I'll keep it for years. I did spend despite the amount is big enough for me, but the sure is I won't accept to keep this card.

Anyway, I went too far -off topic.

do you speak for all amd cards or partculary for gb version? And after all is it good to update to F43 over F42? And do you think that this gb card isn't so good purchase as i was told by almost everyone i've asked?

Yes, I'm talking about all 7xxx AMD cards. The flickering/corruptions/black lines/artifacts ( call it as you prefer ) is a general issue of the 7000 GCN series cards on many Dx9 games. The bad memory latency is a driver issue that certainly affects the 7000 series, and probably the previous series, too.

As I said, this card has a brilliant cooling mechanism and no coil whine. Among all others, I think it's one of the best AMD cards. It's just my opinion, though, and make no mistake, I'm not at all expert on hardware. I got it due to recommendations by other users, likewise. It's truly cool 'n' quiet as I've been told.

If personally you, consider low ASIC as "problem" and you knew from the beginning that Gigabyte is screening the low ASIC cards -here only yourself can answer- would you still proceed to purchase? The problem is, you never know what ASIC your card will have, even if you go to another brand.

About the BIOS, I run the F43 currently... Both are fine, no problem at all and no drawbacks, seemingly at least. I don't know what they mean in release notes, "UEFI BIOS". Do they mean is more compatible if you have UEFI BIOS? I really don't know what's the difference between F42 and F43.
