1  Alternate cryptocurrencies / Mining (Altcoins) / Re: AMD Mem Tweak XL - Read/modify timings/pp/straps on the fly on: October 17, 2019, 08:13:20 PM
1) OK. Thanx. I got 2 rigs at 6 cards each, all cards have same problem. My cards stable at default timings at 950Mhz Memory only and give 38Mh ETH. Overclock 1000Mhz Mem at default timings and system hangs  in ETH mining. weak or conceal timings at 950Mhz Memory and system hangs in ETH mining.  in CNR-mining everything is OK.
2) Nobody has the same cards here in ETH mining with memory tweak?

You are not using any parameters in the claymore bat file for straps. Are you?
I have Sapphire RX Vega 56 (Flashed to 64 bios) with weak timings and 16*16:AAA gets me around 2150 H/s in CRv8 and 42-43 MH/s in ETH. (1100MHz mem)
Didn't face any issue like this but it seems that 38 MH/s is right for 950MHz mem.

1. No extra parameters in Phoenix 4.7 or Claymore 15.
2. for sure 38 MH/s is right for 950MHz mem. But this mem almost doesn't overclock in ETH at any timings.
3. in CNR-mining the same rig works at 1408 Core -1050Mem Mhz and another rig works at 1408 Core -1100Mem Mhz , everything is OK

OK. Thanx. But DAG generation goes every several hours or less on Nicehash so that delay option is worthless. Any other suggestions? Are there no owners of Gigabyte VEGA64 GAMING-OC at all here? Am I the only person who owns such a crap? All my 12 GPUs have same problem with memory tweak and ETH mining

make your cards stable without applying tight timings, core should run at or below 850, load the cards with default timings, run winamdtweak --current > current_mem_timings.txt and improve from there.
btw 12gpu rigs are way harder to manage - takes somewhat exponentially more time to fine-tune comparing to two rigs with 6 cards each

Hello
Did anyone use Gigabyte VEGA64 GAMING-OC dualfan WINDFORCE Samsung Memory  with memory tweak and ETH mining?, what are your settings? I use ppt, With CNR mining for my cards everything  is OK for settings Weaker Vega 64 or flashed 64 (Samsung) from CN_MAX_YOUR_VEGA.txt from Teamredminer i.e. --CL 19 --RAS 30 --RCDRD 12 --RCDWR 6 --RC 44 --RP 13 --RRDS 5 --RRDL 5 --RTP 4 --FAW 18 --CWL 6 --WTRS 4 --WTRL 9 --WR 15 --WRRD 1 --RDWR 18 --REF 17000 --RFC 248 and my voltage is 840mV for Mem and Core, 6 cards at 1408 Core-1050Mhz Mem and give 13600 h/s, about 2250 h/s per card at --cn_config=14*14:AAA, absolutely stable for weeks.
With ETH mining my cards work only with default  timings and  give max 38Mh per card at 990Mhz core- 950Mhz Mem in Phoenix 4.7 and Claymore 15. I tried different timings, latest bios from official gigabyte site and also set higher voltages up to 950mV for Core and Mem, but eth miner with not default timings just hangs in a minute or less after Dag generated and rig restarts . When i set Mem more than 950Mhz, miner hangs in ETH mining at any timings, including default ones. My Gigabyte VEGA64 GAMING-OC have same default timings as any Vega 64 Reference.
My 2xPSUs are OK, they are 1kW GOLD. I have same problem with ETH mining using only one card from that rig

you may have memory not stable enough for intensive stage of DAG generation. simple solution - put delay of 2 minutes or so, in the Task Scheduler for execution of AmdMemTweak
my vegas are stable on ethash from 42(non modded 56) to 49.5. you may have shitty gpu:)
