r9 280x has about 5-6% improvement, r9 390 about 2% slower.

9.3 390 - 313 sol
10.0 390 - 305 sol
is bad

Yes but not that much drop

[oslak]

V10.0 is much more stable but uses more power.

Can u be more specific how much exactly with examples,thx in advance

How to increase hashrate in r9 290 saphire?
claymore v9.3   r9 290- 1050/1500 give only 295-298 h/s with overclock.
How can i get more?
P.S. v10.0 only decreases hash on r9 290 - 290 h/s.

[D8V1D]

RX 480     a2  260h/s

R9 Nano   a1  350h/s

R9 Fury    a2  375h/s


Not sure why the R9 Nano performs better on the algorithm 1.


The R9 Fury has 56 compute units, while the R9 Nano has 64.

In previous versions the R9 Nano has always outperformed the R9 Fury.

I think some more optimization can probably be done on the R9 Nano for v10.


Nice speed increase overall, thanks Claymore!

What does Cannot get Overdrive capabilities for adapter in logs mean?

v10.0:

- improved speed for most cards, up to 8% (depends on card model). About 340H/s on stock 390X, 255H/s on stock RX480, 320H/x on stock Nano.
- added "-a" option to select best algorithm implementation for your GPU.

PS. This is an intermediate version because I had no time to implement all optimizations I planned for this release, also I had no time for tests. In 1-3 days I will release another version with further speedup.

240 sols on my 7950. simply wow. Have to try the 6970

What are your settings? I get 188 h/s on stock

Means your gpu is not stable, increase the voltage or lower your clocks, or check for other errors

 v10.0 only decreases hash r9 390 yf 1-2%.who took the decision?

[ivomm]

For all my cards I get 4% improvement. I got it for undervolted and overlocked 390 with -a 1, and 280x with -a 1 or -a 2 depending on the model. For example XFX are better with -a 2 (215 sols vs 210 with -a 1), while Saphire Tri x is way better with -a 1, where I get 230 sols on stock cards vs 218 with -a 2.

[roony]

Nice improvements 

[pilotbtc1]

I changed and 0..3, increased the voltage across avterburner not help hash is less than 1 - 2%?

[andrew2k]

I had 256H/s for my RX 480 8GB now it's at 286H/s, massive improvement for these cards. (It is overclocked to 1370/2250.)

[roony]

Guys, what clocks are you using on rx 470 4gb?

[Qazo]

really nice speedup for my 2x480
but I'm seeing this




only for GPU0, same OC settings for both cards

1340 - 1040mv, 2100 - 1000mv


I didn't have that problem with 9.3 version, any suggestions?

That's way too much. The sweet spot is 1100-1150mhz core and 0.9V and around 210-220mh.

Just tested with your settings, I'm getting much lower hashrate (about 230-240 per card) and about 15 W less power.  So, back to my settings

I had 256H/s for my RX 480 8GB now it's at 286H/s, massive improvement for these cards. (It is overclocked to 1370/2250.)

Sapphire OC or? how you clocked memory to 2250? Custom bios or?

v10.0 only decreases hash r9 390 yf 1-2%.who took the decision?

If you want to use Algo option use -a 1 for 390s otherwise disable it with # -a 1,2

[pilotbtc1]

I put a 1, it is useless, my card R9 390 hash decreased by 1-2%

[bitcoinsay]

Better than nothing. Nice work.
