Is it normal for 780's to have different boost clocks? In precision X @ +140 one does 1163Mhz while the other does 1134Mhz or something. Is there a reason they aren't boosting to the same clocks?

It can go based off of your temperature or tdp, how much voltage will also affect it. Also depending on the video card you get, say.. DC2, SC, Gaming, Windforce, whatever.. different bios will have different tweaks so they will all have different boost clocks. Of course you could have similarly/the same if you have the exact same model/bios loaded on to it.

Alternatively if you're on SLI or have multiple cards, one can be running hotter than the other and may cause some lowering.

If you look at the kepler bios editor you can see the tables it sets certain clocks for different voltages.

Hi all smile.gif

I have a Palit 780 reference board, which of the 3A BIOS should I choose? or does it not matter? I notice the files sizes vary between them?

Just a bit confusing guys.

Thanks for any help smile.gif

Does ASIC quality affect the frequency?

I have one classified that is 75.7 ASIC and boosts to 1137 mhz and the second is 79.8 and boosts at 1150 mhz.

or is it just coincidence?

Based on what I've seen stock boost does have something to do with ASIC. My higher ASIC cards have boosted higher (at stock) than my lower ASIC cards.

But I've also found that ASIC (for me at least) hasn't been a good indicator of overclocking potential. My best clocking GTX 780 Classified (on air) had the lowest ASIC.

No, at best its a voltage leakage indicator, have a read from one of my articles:

"ASIC score is more an indication for nvidia and amd and for us only a measure of leakage in our chips (thanks to W1zzard from TechPowerup we can see the value in GPUz), its good to know the ASIC if youre going to run SLI because it want to have closely similar ASIC score on your cards because they will have similar voltages and you can clock/volt them together without having to go separate settings if you get big difference ASIC ( i.e: 60% - 80%)
@TSMC for nvidia and FAB1 for AMD, as the chips are removed from the waffer, are tested and fused with the voltage that is reflected on the leakage of every chip!

Originally Posted by Dave Baumann Product manager AMD about ASIC
"Actually, it does the opposite! We scale the voltage based on leakage, so the higher leakage parts use lower voltage and the lower leakage parts use a higher voltage - what this is does narrow the entire TDP range of the product. Everything is qualified at worst case anyway; all the TDP calcs and the fan settings are completed on the worst case for the product range"

A high leakage card operates at lower voltage to balance the otherwise higher power draw and temps. It will also overclock higher than what a low leakage card would. The problem is though, cards usually have a limit of voltage increase, i.e. say +150mV , which means AB could overvolt a 1.15V card to 1.3V, but a 1.1V card would crash above 1.25V.

A high leakage card is what you want if you do extreme OC, and you can keep the card cool (H20,LN2 etc.). Your mileage will vary of course, not all low VID cards are good OC cards, and not all high VID cards OC bad. It's a part of product binning, they try to fit in as many chips as possible to a similar ASIC spec.

From "the man" himself W1zzard - Techpowerup:

"it's from the gpu silicon, and it's used to calculate the gpu voltage.

"bad" gpus get a higher voltage so they make the default clock. "good" gpus can do it with lower voltage

as you've seen in this thread, the scale for nvidia isnt perfect yet, so i'll apply some fixes once I have more data that suggests the typical ranges of gpu leakages"

There is no correlation to OC besides the voltage leakage but from there you can extrapolate some values, not that any particular ASIC will give you a particular OC but it will tell you you going to need more or less voltage to do it; another thing is ASIC is percentage based but we can group them, meaning some values will fall within a certain voltage:

ASIC quality < 75% - 1.1750 V
ASIC quality < 80% - 1.1125 V
ASIC quality < 85% - 1.0500 V
ASIC quality < 90% - 1.0250 V
ASIC quality = 100% - 1.0250 V
