zawawa, can't you say how in gg (or sgminer) force to not initialize 1 of cards? F.e. if i have 2 cards even with option --devices miner initializes both of cards and load kernels for them but on 1 cards just stay OFF.
I want to mine though gg miner 1 algo on 1st card and 2nd algo via other miner on 2nd card. But gg initialize 2nd card and reduce speed on other miner.

I don't think that's possible with GG or sgminer.
I am rewriting GG in C# now, and I will make sure to fix the problem.

Thanks! I'll wait. And some time ago you promised to add optimiztions for GCN1.0 cards...

Anyway, great work! Keep going...

Hello everyone.
I am having a problem with GG and cryptonight mining.
On every pool that has variable difficulty, eventually your miner will be assigned a high diff and if GG will not find a share for 90 seconds
it will disconnect, upon reconnect diff will be at whatever starting diff port you have chosen and the whole cycle repeats.
Overall hashing speed takes a hit from all the disconnects.
I think the following code is responsible for the disconnect (gatelessgate.c):

Code:

        /* The protocol specifies that notify messages should be sent
         * every minute so if we fail to receive any for 90 seconds we
         * assume the connection has been dropped and treat this pool
         * as dead */
        if (!sock_full(pool) && (sel_ret = select(pool->sock + 1, &rd, NULL, NULL, &timeout)) < 1) {
            applog(LOG_DEBUG, "Stratum select failed on %s with value %d", get_pool_name(pool), sel_ret);
            s = NULL;
        } else
            s = recv_line(pool);

        if (!s) {
            applog(LOG_NOTICE, "Stratum connection to %s interrupted", get_pool_name(pool));
            pool->getfail_occasions++;
            total_go++;

And the static initialization of the timeout a few lines above:

Code:

        timeout.tv_sec = 90;
        timeout.tv_usec = 0;

This disconnect does not occur on xmr_stak miners.

A workaround is setting a low enough fixed diff to ensure max share time < 90 sec, unfortunately most pools do not support fixed diff.

Is ~500 kh/S pretty decent for an RX480 @ stock speed on this miner on NeoScrypt ?

Thanks!

No, you should get at least 700 KH/s.

Seems like the rejects are normal as nicehash doesn't accept stales (i've seen some go through though).
A solution would be

Code:

"no-submit-stale": true

to rule out any problems with the rig.

I'm not talking about nicehash.
There're very high rejects rates (3-5%) on SGminer-GM running both XMR and SUMO on different pools. And slightly lower (about 3%) on GG.
There is a major update to Claymore's cryptonight miner coming - so we'll see how it differs soon...

Hi, Would you know where I can get information on how to read all the interface data. I see two hashrates close to each other, a HW, a WU... is there some more info somewhere?? many tks

XMR - Is anybody experiencing a high reject rate (1% - 3% per card) and stratum connection disruptions on nicehash with this miner?

I just tried switching from miningpoolhub to nicehash and having the same problem I even tried the nicehash sgminer-gm fork and the same thing it has to be nicehash

yep cryptonight seems to be the most sensitive in regard to rejects and hw errors.
all my polaris cards are steady at 1.5-2% rejects, here's the sample:

EDIT: latest sgminer-gm apparently produces slightly better rates (about 2% for me) than GG

EDIT2: you guys should try sgminer-gm 5.5.5 ~~also does 0 rejects on the same pool where GG was having ~2%~~ - not really, it actually makes more rejects, but maybe your cards would do better than mine...

hi guyz.
will 0.1.3-pre6b ggate work with RX 5xx?

Its actually the best for XMR I think, but could not make it mine ethereum and other coins on same algo

This does work on RX 5xx (mining XMR at least) You just need to find the right settings to optimize your cards.

Just got to use this with my r9 280x and love it!! Getting about 200 sol/s.

Old 280x cards with claymore's miner(and I think with optiminer's miner too) can show more better results - up to 325 sol/s with modded timings.

It's true. With 12.5 Claymore I have on my 280X 330-335 Sol/s with modded bios, overclocked memory and downvolted core.
Optiminer gives only 275-300 Sol/s.

For anyone still following this I did endup finishing with 1075core/1500mem and undervolting to 1.021v (Stock for 1030core is 1.2v). Averaging 320sol/s. Intensity 6!!! Intensity 7 requires more than 3gb ram on card. I cant complain about temp being 66c with fans on 30%. My r9 has Samsung memory and no matter what mem clock I tried the sol/s decreased. Cheers... maybe next I'll try excavator.
This card is PowerColor TurboDuo R9 280X OC

I got it all working with 15.12 drivers. The card needs a display plugged into it or fans and overclocking can't be managed. So I have an hdmi plug from it to my monitor even though I don't use it's display. I'm using -pwrlim 20 and a 1100 core. Is that max? I'm around 370sol/s

I'll look for an older version of AB when I get home

I don't think that you recieve more speed with 15.12. I tried many times with many miners. And on 15.12 I get the same speed as on last new drivers.

I installed drivers 15.12 and switched my display to onboard. None of my overclock software works. It shows my video card and I can mine fine but can't adjust overclock settings

Maybe new overclock software (AB?) didn't support old drivers?
