gtx 1060 mining gpu

[Cheetahgod]

I got the gpu today in the mail. It was packaged in a thin layer of bubble rap in a gray plastic bag. The frame was badly bent and a tantalum cap from the back of the card was loose in the package. Despite this I was able to bend it back and get the card working. Getting 270 Gz days per day trial factoring with mfaktc.

Indeed, I have one running and with some tuning I get a constant 825 Ghz-d/days.

Sounds a little low to me. Did you mean to type 925?

~923 combined.

This is with GPUSieveSize=2047.

No I am getting 270 Gz/day. How do I change the sieve size. I am using a sieve size of 82485.

See https://www.mersenneforum.org/showpo...99&postcount=8 and your mfaktc.ini file for tuning.
I would get typically over 500 GhzD/day TF on my gtx1060 with a single instance.

no factor for M110016017 from 2^75 to 2^76 [mfaktc 0.21 barrett76_mul32_gs]

My preceding message was in reply to aheefer regarding a gtx1650, for which 825 GhzD/day may be right if power is being limited for efficiency.

I see 467+430 = 897 ?

Whoops, must not have been fully awake yet.

Wow TIL, thanks. I got a 9% increase on the recompiled version with GPUSieveSize=2047 (up from 128) on a RTX2070 (non-super)!!!

(Downloads are here and then pick a version ending in "-2047.zip")

The P106-90 has half the cores as the regular gtx 1060.
It has 768 cores whereas the 1060 has 1152 (3gb) or 1280 (6gb).
I was able to get 300 ghz/day by increasing the clock speed. Changing gpusieve has little affect on the speed.

My gtx1060 is a 3gb with no overclock, 514.6GhzD/day, and that's running at reduced power, 60W not the 140W max.
514.6 /1152 * 768 ~ 343 GhzD/day predicted for your P106-90.
I got around 330. after tuning a GTX 1050Ti.

I download the 2047 version and replaced the exe with the previous one. I then changed GPUSieveSize from 64 to 2047. I am not getting any significant improvement. Does this look right? At about 295 with the gpu overclocked by 200mhz and memory 600mhz
