Woke up this morning to majority of my shares being rejected.

I'm assuming this was because memory was set so high (1900 mhz) I pulled it down to 1850 (925) to see if this helps.

What GPU do you have?
Invalid shares are usually due to invalid timings on gpus , if you get them after modification.

I recorded a video with the process, and when I reopen the rom with the modified straps, they are the same as those in estock rom, do you know what the problem is?

I think there is bug in software , when you save it is actually edited. When you reopen , it shows edited timings but when you click on it it shows previous timing. But the saved file contains actually your edited timings. Tried this myself and replicated your problem. Did you upload edited timings to your gpu. 2nd set of timings was for me that increased performance significantly.

I dont have any of these gpus wouldn't be able to to tell.

1850 was bad too... Dropped to 1825.

Hi,
I have 731F Navi10 GD25Q80C 113-R_170_XL_NAVI  (5700 non xt) with romsize 1MB, seems RBE can't edit 1MB romfiles. I should edit downloaded 512KB and force flash? or wait RBE update?
Thank you

[NCarter84]

I flashed back as I couldn't control the incorrect shares.

What speeds you where getting?
I think you might need different timings , you can try to copy 2nd last to last.

I have all 4 reference 5700 cards flashed to XT and mining around 55mhs. any advice to get them to 57-59?

Perfect thanks flashed and mining now 57 mhs

try Core 1300
memory 1850

[NCarter84]

I may have figured it out.

Flashed back and was still getting rejected shares.

Then realized I was still using 4.7, upgraded to 4.9 and so far so good.

Cool great it worked out, im hashing quite stable. Will try to modify power usage tomorrow http://prntscr.com/rbpoh8 1 incorrect share in nearly 8 hours and 1070 valid

I will wait anxious to see if you can reduce the power usage
If you reduce to at least 10% (13w) and with the 10% of speed increase you already achieve, it will be AWESOME, and the card will be the best hashrate per watt

I've done nothing in terms of power yet - but I can say I've been running for 2.5 hours without a rejected share.

I need to allow it to run over night and see if the pool actual gets what the miner is saying it should get...

I did see roughly 20w increase in power.... But, I also have one card running at 900mv.

[NCarter84]

Mineshop, id be interested in what the console miner shows for your pool side hashrate?

So far, I'm about 10% low but it's a super small sample size.

I think it is achievable currently running 3 cards and watt meter on wall showing 470w, so it is about 140watts per card +50w cpu
What i see really strange with these timings, is that hashrate increases significantly only when i increase core clock, memory clock does very little changes. I can leave it under 920 and core 1400 they get hash 58mh/s
