I have now adjusted vardiff to push up more agressively than down, that should help with this.

zhpool still better by now
with 1gh     33Mh/s
with zhpool 40Mh/s

I have now adjusted vardiff to push up more agressively than down, that should help with this.

I just tried it out and it's not any better unfortunately. (I've left it for good 20mins also)

7850 @ 1GH = 5.38 MH/s (before)
7850 @ 1GH = 5.40 MH/s (now) (diff hovers around 0.010549)
7850 @ ZHP = 6.30 MH/s (fix diff 0.20000)

280x @ 1GH = 10.50 MH/s (before)
280x @ 1GH = 10.50 MH/s (now) (diff hovers between 0.022220 - 0.029832)
280x @ ZHP = 11.49 MH/s (fix diff 0.20000)

It doesn't help. We need ~0.2 diff
Maybe use string in password to force higher diff?

why i cant connect ?

[2014-03-27 14:35:55] stratum_subscribe timed out
[2014-03-27 14:35:55] ...retry after 30 seconds

now its ok

My bad: I have made a wrong adjustment and vardiff stopped upping the difficulty at all, overloading servers with huge number of low-diff shares. This is fixed now. On the bright side, an improved miner is soon to be released.

What kind of hashrate is 0.2 optimal for? For ~22Mhs vardiff now settles at about 0.14 and this means 4 shares/min, anything above is probably prone to generating quite a few stales.

I'm seeing diff 4.xx & 2.xx now. It gives 1Mhash/s more per 280x (rig with 4x 280x)


So:
diff <0.1  - 9.60Mhash per 280x
diff 0.1-0.18?  - 9.63Mhash per 280x
diff 0.19+    -  10.55Mhash per 280x
diff 2.xx, 4.xx - 11.4x Mhash per 280x

Now I think it's worse. It goes to extremes from such low diff that it spams server and hashrate drops to 7.xx Mhash (280x) to such high diff that all I get are reject/stales.

ccminer 0.5 is out... hashspeeds are much better than amd cards... 750ti reports 13Mh/s (that is better than a 280x)

@reorder: sounds like a challenge to optimize cgminer better...
don't let nvidia beat amd 

greetings

It is underway, this is for non-oc 280x:

Code:

GPU 1:  68.0C 2848RPM | 14.54M/13.70Mh/s | R:0.1% HW:0 WU:0.0/m T:1 xI:105

However, I am still busy adjusting vardiff.

I still get 11M for 280x. Can you share your config to reach 14M?

It is not related to config, it is the next version of miner.

I'd appreciate if someone could point out if I'm missing something obvious here:

Downloaded current version of cgminer Windows binary from hvc.1gh.com. "Out of the box" I could get up to 10.5 MH/s on a 280X, x-intensity 105.

Compiled current version of cgminer on Debian, only gets 8.3 MH/s on the same card, same settings. Not just the same type of card, but the same exact machine dual-booted between Windows and Linux.

What could be the issue with the Linux version? I followed the instructions on github to compile it. AMD Catalyst 13.12 on both Windows and Linux.

Most probably you have not put ADL SDK include files to their directory, and cgminer now cannot detect the correct gpu-threads value (1).

Is that the T:1 value? I downloaded ADL and copied the includes before configuring/compiling. It shows this now:

 Connected to hvcpool.1gh.com diff 0 with stratum as user xxxx
 Pool 0  Diff: 1.95K  Started: [18:11:43]  Best share: 2

Any other ideas? Thanks.

You can now enable fixed 0.28 difficulty by using 'VIP' as password. I gave up on trying to make a vardiff algo suitable both for fast and slow miners.

Maybe you have checked out the previous version from git? 'git pull' in the source directory should help in this case. Anyway, I am close to releasing the improved miner, it will be ready in a few hours.

Ok, I won't bother you anymore so that you could focus on that

I'll wait for the new version and recompile. Thanks!

Seeing Nvidia's performance boost lately, I know you have more aces in sleeve for AMD gpus

R9 280x will be at 25Mh/s range or more, if small nV 750-ti is at 13Mh/s

Keep up the good work !
