I'm working on compiling data, mostly to sate my curiosity, related to ASIC and its effect on a card's stock performance.
 
If you want to contribute, you can grab your ASIC score and Boost GPU Core Clock easily from GPU-Z. To get your card's ASIC, open up GPU-Z, right-click in the top left corner, and select "Read ASIC Quality." To get your boost clock, an easy way is to get OC Scanner X, select the 3d test "Plasma (1M-particle)," then run it and note your GPU Core Clock listed under load in the Sensors tab of GPU-Z.
 
Here are three EVGA GTX 970 FTW cards with their ASIC scores and their boost clocks with 100% default settings. I also took a look at the BIOS of the 970 FTW and grabbed the index of the Boost Table (out of 74) that most likely correlates with each.
 
My Data
ASIC 65.0% | Boost 1379.5 MHz | Boost Clock #62 (1380.0)
ASIC 67.9% | Boost 1392.2 MHz | Boost Clock #63 (1392.5)

Overclock @ Stock
For those of you who are comfortable with overclocking and know how to properly test for stability, do you mind posting your maximum stable core clock overclock as recorded in GPU-Z with OC Scanner's Plasma test?
 
I consider stable to be no artifacting or driver crashes in Fire Strike, no issues with Furry Donut v2 (I tend to test for 5-15 minutes, but it usually crashes very quickly once I reach unstable numbers), and no issues running Valley benchmark Extreme HD.
 
ONLY adjust your core clock, not your power, voltage, or memory. It'll help us compare apples to apples again.
 
ASIC 67.9% | OC @ Stock 1442.? MHz (+50 Offset) | OP
ASIC 68.7% | OC @ Stock(?) ~1525 MHz| un4givn85
ASIC 73.1% | OC @ Stock ~1480 MHz | painis4thaweak
ASIC 75.?% | OC @ Stock 1510 MHz  | staypuft
ASIC 76.8% | OC @ Stock 1496.6 MHz (+79 Offset) | OP
ASIC 78.3% | OC @ Stock 1581.2 MHz (+151 Offset) | ManBearPig
ASIC 79.8% | OC @ Stock ~1490MHz | painis4thaweak
 
I can also tell you that the higher ASIC card overclocks much more stably on air without any adjustments apart from core clock speed.
 
I found Furry Donut 2 (part of EVGA OC Scanner X) to be a pretty reliable indicator of stability. It crashes almost instantly when a card's core is clocked too high.
 
I couldn't go much higher than a +40 offset on the ASIC 65.0% card (failed to write down exact numbers for this, but it was below +50). I can go to +50 (core clock of ~1442MHz) on the card with an ASIC of 67.9%. I can get to +79 (core clock of ~1496MHz) on the ASIC 76.8% card.
 
Once voltage is applied and/or BIOSes are edited, the numbers can certainly change (e.g. the ASIC 67.9% card can get to a stable boost of 1531MHz with BIOS changes on air while remaining well below 70 °F), but the majority of users are going to stay away from editing their BIOS, even on a card like the 970 FTW that provides multiple BIOSes to protect you for wrecking your card.
 
I suppose if I make that argument, though, most users aren't going to overclock their pre-overclocked cards anyway.
 
If the are other 970 FTW users out there who can post their ASIC and Boost clock at stock, we can compile some useful information, even if it's just for the sake of our own interest and examination and yields nothing tangibly useful.
 
It's also possible that it would be better to do this with the Gigabyte G1 Gaming since it seems be the most popular GTX 970 with overclockers. I'm still sticking with EVGA because their customer service is amazing and they are based in the US.

Mine at stock:
ASIC - 73.4%
Boost Clock - 1404 Mhz

Thanks, guys! This data is very interesting.
 
So far, it seems the hypothesis that higher ASIC directly correlates with stock boost is true. We'll need more samples to extrapolate a lot of useful information from it, but so far...
 
It appears there's a ~5% range for each boost bin.
 
Something like this seems to be developing:
ASIC 61-65% = Boost Bin #62
ASIC 66-70% = Boost Bin #63
ASIC 71-75% = Boost Bin #64
ASIC 76-80% = Boost Bin #65
ASIC 81-85% = Boost Bin #66
 
The last one isn't supported with data in this thread as of yet, but the Hardware Canucks review had its 970 FTW stock boost at 1430 MHz, which likely means they had a higher ASIC card than the rest of us for the review.

970 FTW 1:
ASIC = 78.3%
Boost = 1430.2 MHz
 
970 FTW 2:
ASIC = 77.7%
Boost = 1429.8 MHz
 
That is with everything stock.  I don't know what my maximum OC is yet, haven't pushed them that far since there is no game that needs that much.  But I was able to get them up to 1550 MHz and I when I game, they are at 1525 MHz.

Stock 970 FTW
ASIC: 64.3%
Boost: 1379.5 MHz

This is what mine looks like, both have the same BIOS

ASIC on my card is 68.4% and stock boost is 1392.2MHz.

Airwolf24
ASIC: 70.3%
Boost: 1367MHz

That is the stock overclock, not the actual boost. You can see your boost by grabbing something like GPU-Z (look at the Sensors tab) and running OC Scanner's Plasma test. Your boost is likely 1392 or 1405.

FWIW, I have an SC with 75% ASIC, factory boost 1380MHz, max OC boost is 1510MHz.  New FTW coming soon and will post those numbers.

970 FTW Card 1: ASIC - 73.1% ; Boost - ~1480MHz (under F @ H)
970 FTW Card 2: ASIC - 79.8% ; Boost - ~1490MHz (under F @ H)
 
Both cards have returned successful work units up to 1510MHz core. Haven't attempted a higher OC.
 

My SSC has a 68.7% ASIC. Stock boost is 1392. Max oc for folding so far is 1525. Those same settings get about 1480 due to the power limit.

Boost: 1404.4 MHz
ASIC Quality: 71.1%

that's exactly what I thought as well reading the numbers. 

so can we say 84.04.1F.00.75 is the most latest one? I did not update the bios.
 
did you use r0ach's modded bios? he has increased the power limit as far as know.

do you notice any difference between 84.04.28.00.71 and 84.04.1F.00.75 versions?
