Looking for volunteers with Fiji GPUs to figure out ASIC Quality

[Szb84]

Thanks just tested it with my Fury OC:

I would have assumed with 1.212V I'd have higher quality ASIC (High LeakageID)?

I currently don't have the other 3 Fiji cards I owned, but their DPM 7 VID on stock ROM / settings was:-

Fury Tri-X STD 1.243V @ 1000MHz DPM 7
Fury X 1.250V @ 1050MHz DPM 7
Fury X 1.187V @ 1050MHz DPM 7

I would have assumed from the information by the Stilt that the samples which were 1.250V or close to it would have been Lower ASIC Quality (Lower LeakageID).

I have another card coming within the next few days and will check and post screenie of that.

@Szaby59 are you able to do registers dump via AiDA64 when on stock ROM / settings? cheers

DPM0: GPUClock = 300 MHz, VID = 0.90000 V
DPM1: GPUClock = 508 MHz, VID = 0.93100 V
DPM2: GPUClock = 717 MHz, VID = 0.93700 V
DPM3: GPUClock = 874 MHz, VID = 1.03700 V
DPM4: GPUClock = 911 MHz, VID = 1.07500 V
DPM5: GPUClock = 944 MHz, VID = 1.11200 V
DPM6: GPUClock = 974 MHz, VID = 1.15300 V
DPM7: GPUClock = 1040 MHz, VID = 1.25000 V

Not just the DPM7 all are affected except 0 since from 1-7 the voltage is generated depending on the chip quality.

Cheers , the Fury Tri-X OC ROM is invalid for assessing stock VID DPM 7 IMO, as it's not at AMD stock clocks for Fury.

AFAIK the driver/ROM under EVV calculates VID per DPM at AMD clocks, deviating from it creates anomaly.

For example if I changed DPM 7 frequency on my Fury Tri-X STD to greater than 1000MHz I'd get 1.250V. In the case of Fury X cards which I had where DPM 7 @ 1050MHz lower than 1.250V increasing clock above 1050MHz resulted in 1.250V. The max EVV mode will make DPM 7 is 1.250V with clock changes from AMD stock.

"Not just the DPM7 all are affected except 0 since from 1-7 the voltage is generated depending on the chip quality."

Yes, indeed .

Default GPU clock per DPM + LeakageID + other GPU properties.

From what the Stilt stated in the case of other gen ASIC was within LeakageID band there is also good / bad ASIC. For example we take two identical LeakageID ASIC, one good and other bad, the bad ASIC will end up with higher VID where as good ASIC lower VID.

Everybody with Fiji: please download GPU-Z 0.8.8, go to the validation tab and click submit, no need to fill out anything.

This will record your ASIC quality, for comparison with everybody else's.

At the moment there are only a few Fiji's in there, so your relative score is unrealistic.

OK, cheers for info , I'll highlight to members on OCN owners club plus the Fiji bios mod thread to do validation .

here is my Fury X

Here's some of mine. Both are Nano. (took them yesterday before others started to check theirs "the reason why the percentage is still so high compared to others").

As mentioned over @ OCN, Nano's seem to show lower Asic quality than Fury (x)'s..

Both cards run stable with an undervolt of -100mV at stock core clock 1000 but with the memory decreased to 300.
