Gateless Gate Sharp 1.3.8: 30Mh/s (Ethash) on RX 480!

[ayiphelmy]

r9 390 and 1070ti in 1 rig mining gobyte @ pool altminer, this is first time i try this software but not working for me... do you have solution??
[/quote]

I was able to mine GoByte at altminer.net with RX 480, so it is probably that GGS's NeoScrypt kernel is not compatible with 1070 Ti. I will see if it works with my 1080 Ti.

in my rig there is 2 390 and 4 1070ti all not work even i try only select 390  and i try diffrent pool like www.unimining.net same problem.... if i use original sg miner gatelessgate it's work fine with amd only
[/quote]

Try 192, 128, and 64 for Local Work Size. They may work.

ok let's se if that work i let u know

Still not working

Hello everyone

Does somebody know why I get this error?

zawawa, please update source code on github to 1.1.20. It's 1.1.19 everywhere...

Current Roadmap (Subject to Change)
3. On-the-fly memory timing mods and other optimizations (two weeks?)

I've been thinking of doing that since I wrote my strapmod uitilites several months ago.
https://github.com/nerdralph/strapread

strapmod.py makes a few changes that improve performance, and seem to be safe on Samsung, Elpida/Micron and Hynix RAM.  Modifying other parameters in a generic way is much more problematic.
I'd be interested if you find anything that can identify the specific RAM type.  Utilities like amdmeminfo can tell you a card has H5GC4H24AJR memory on it, but not if it is -ROC or -T2C.

NeoScrypt performance is too low for 980 Ti.

300 kh/s with GGS, and 730 kh/s with ccminer...

I didn't sure that strapmod is safe for Hynix MJR VRAM. I try it and memory became unstable. Miners start to BSOD all system.

Thanks for the info.  Any idea which change was the problem?  I've heard some people say it's not always safe to zero FAW & 32AW, but couldn't find a card that failed.  I've got cards with H5GQ4H24MFR and H5GC4H24AJR , but not H5GC8H24MJR.

Yes, zeroing FAW & 32AW leads to bugs. But situation is next:
1. I use good strap for hynux mjr.
2. I try to overclock and undervolte.
3. Recieving stable config, f.e. memory clock 2150 at voltage 0.9V
4. After try to apply strapmod, flashing bios and restarting. And after this my config became unstable.

I think that if take native bios and apply strapmod, it will work at 2000MHz and will give more speed. Maybe it even will work at good strap at 2000MHz, but it's mean that maximum stable clock is down with strapmod. And I don't know - zeroing FAW & 32AW gives more speed than higher memory clock...

Tighter timings can't be pushed as far, so I suspect that is really the issue.  i.e. I think it is safe to apply the strapmod changes (RRD=5, FAW&32AW=0, ACTRD=16), but you won't be able to overclock the memory as much.  If 2150 is stable without the strapmod changes, then I bet 2050-2100 should still be stable with the changes.

But will strapmod give more speed than 100MHz overclock? And for wich algos strapmod gives more speed?

Probably for ethash.  And probably for equihash too, though there is room for more tweaking when it comes to equihash.  I haven't tested cryptonight.
Memory will consume 5% less power at 2050 vs 2150, and so the memory will also run cooler.

Thanks, I will try it.
How knows what timings in straps is more important for cryptonight?

[zawawa]

GGS takes control of gpu-fan speed... and I unchecked "Enable" in "Devices" tab. I prefer Afterburner control but GGS don't let it.

I got to fix that one for sure... I will push a fix in 10 minutes or so.

what about neoscrypt? i still can't use your miner in hawaii and 1070ti... i anly tested in 1 rig... 40 to go

See I don't have 1070 Ti right now... I have 1080 and 1070, though. Let me see if they work...

Thank you very much!!. Works fine now.

See, I did months of experiments with memory timing mods, and I didn't find these strapmod changes particularly safe, at least with RX 470/480. 32AW=0 was especially dangerous, and I also found that ACTRD=16 to be too low in some cases. With Equihash, anything below ACTRD=23 hurts performance IIRC. I cannot wait to get back to these mods. We will see...

[ironandrey]

Great job Zawawa!
On your miner gateless gate v0.1.3-pre1 I was able to achieve my rx570 nitro+ (hynix) card up to 900-915 hash. (Works without interruptions for two weeks non stop. Much better than Claymore 11.2)
Thank you very much.
Go on...
