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

[coke15]

hi zawawa

the stable version is very good:)

but 2 (little)things :
-when it config and save the parameter,the sqlite freeze ggs for 1-2 minutes (maybe my hard drive? not a ssd)
-possible to implement an option to restart ggs or restart rig if hasrate of one or more cards hangs,freeze.  ex: if our hasrate for cards is 30,if it drop to  a value we put,ex 25 it restart automaticaly itself. or if the drop is recurent  restart the rig.

it would be awesome

Gonna back to 1.2.11.

Bc 1.2.18 is not stable at all for 280/290 RIG.

What unstable exactly?

I can confirm this too, 1.2.18 is unstable for one of my rigs, other rigs have 4 or less cards and 1.2.18 is working fine on them but this one with 6x cards(390 and furys mixed) can only mine for about 45min and then the rig restarts out of the blue, I'm not sure why.[Neoscrypt mining]
I've tried 1.2.11. alpha and it's more stable so far(atm mining for 1h:42min and still going) than 1.2.18. at least for situation like this (390+fury cards rig)

While mining on 1.2.11 alpha I'm using default 1.2.18 settings for 390 and fury cards, all cards are stock and no oc, the same settings as if I would've mined on 1.2.18.

What seems to be the cause of these crashes on 1.2.18? can somebody elaborate?

win10 x64 v1709

intel pentium G3260

Hmm... I don't see anything problematic in your setup. The only thing I could think of at this moment is Hawaii's ridiculously high power consumption. This, combined with the demanding NeoScrypt kernel of GGS, could be a real problem. I would try lowering the core voltage of 390 by 50mV or 100mV to see if the rig would be more stable.

Windows won't even boot up without freezing anymore this is the second time GGS made me have to reinstall windows. Original GG was way more stable

You can stop auto-start by holding a Shift key.
Also, I am pretty sure you read a warning about modded BIOS.
I would really like to help more, but there is only so much I can do with the limited information you gave me.

I do have modded bios on my RX 470s (1500 straps) is that the problem for all the freezing?

1500 straps could be a real stretch, depending on how high the memory clock is, so I wouldn't rule them out as a cause of instability.

By the way, you can pretty much achieve the same effect by copying only MC_SEQ_MISC1/3/8 from 1500 straps  to the target straps and then applying nerdralph's strapmods (ACTRD=16, FAW=0, T32AW=0, TRRD=5). I have been scratching my head for the last few days in order to stabilize real-time memory timing mods and discovered a few new tricks here and there.

have you been able to improve ubermix 3.1?
how is it going with vega?

Does this mean that in any bios it's enought to take original bios straps and copy MC_SEQ_MISC1/3/8 from 1500 strap to 1750-2250 and then applying nerdralph's strapmods (ACTRD=16, FAW=0, T32AW=0, TRRD=5) will give the same cryptonight speed as modded bios?
I don't think that it will work on Hynix MJR memory. They straps maked by ill mind...
For example, thats some of my original straps from RX 580 8Gb hynix MJR:
1500 - 999000000000000022339D00CE516A3E80551212B40B450A004AE400750314204A8900A00200712 4150F2A30A4283516
1625 - 999000000000000022449D00105A7B4480551312B88C250B004C0401750514204A8900A00200712 417112E34B22A3916
1750 - 999000000000000022559D0031627C4990551313BC0D060C004C04017D0714204A8900A00200712 419123138C02D3D17

2250 - BBB000000000000033BB9D00D6FEAF5EC05517174BD1770F005264011E0E14204A8900A00300712 420173F48F7384C1A

More or less yes, but FAW/T32AW zeroing is not always the best ... as "Speed" is not the only thing we need - we also need stability

That's right. I'm planning to expose ACTRD, ACTWR, FAW, T32AW, TRRD, and MC_SEQ_MISC1/3/8 so that you guys could play with them.
For CryptoNight, you also need to tweak ACTWR. I'm getting around 900 h/s with CryptoNight and RX 480 without overclocking.
Let's see if I can get this stable...

Sounds very promissing ! Remembers me a bit on the "good old times" when we overclocked DDR/DDR2 Rams on Socket 939 or on the 1st batch of Intel Core2Duos ... If ya need a helping/testing hand - just lemme know 

[burntmytoast]

The straps might be an issue but usually I have seen freezing has more to do the overclock settings.

Just reflashed the bios to original and still unstable my setup is 6x Rx 470 using a 4x port multiplier with an old dx7500 motherboard intel e8400 processor its a budget build but works fine with other miners like Claymore, just can't get it running stable on this :/. My other rig using a new motherboard and no port multiplier is running this stable

[Ambros]

I have always been a Claymore guy, but your work is simply amazing. I just tried it on a few windows rigs and it works like a charm!

I look forward to seeing it on Linux so that I can deploy it to production.
Keep up the great work!

[z97rx470]

Whenever the pool goes down the miner will cause windows to freeze/crash... I have a really hard time getting back running after that as I keep getting a BSOD "Thread stuck in device driver" like 30 seconds after the desktop boots up with nothing running.. It was stable all day until my pool went down now I can't even get back into windows... might have to reformat again

This is no good... Which driver are you using with which card?

[zawawa]

a 4x port multipler

Ah, an important detail! Thank you. I always wondered about those 4x port multipliers.
Which algo are you using? Are other algos working at all?

[duyquang06]

When do u start optimize for Vega ? just asking 

[oossaa]

Great job, dev!  Please, if you may, to add algo blake2s (for XVG)

hey there
I'm having bad issues with this miner since some of the very first releases.
this was my third attempt to make it work with 1.2.18 stable version
the machine is asrock h110 with 8*1060 and 2 vegas FE, drivers are pro q4-2017.
vegas are underutilized as I have no time to deal with it proper, so I thought/sorta hoped that I'll get somewhat better results from them with gg-sharp, as it currently produces very stable 1200-1300 on xmr.(on GG)  I'm using overdrive for clocks and volts.

It tends to work for a while(I'm selecting only 2 Vegas FE and it gives about 1.2KH each on XMR), but then it either hangs or crashes somehow.
 this time it did something that caused me to loose my card physically from the remote system (normally working fine for months), probably pulled to much power and one of my raisers got some issues with 12V (freaking molex power!)

Is there any experience with "pro" amd drivers?
Maybe other suggestions for Vega FE?

[UnclWish]

Hynix MJR memory is very unstable with TRRD=5 but more speedy on cryptonight.
Does anyone knows what straps parameters can make memory more stable?

What about bug with rejected shares after recieving new job before share accepted? Bug is still exists...

And it's need more info about current difficulty and reasons of rejecting shares.
