first steps with hiveos...any hints where i can find the tool or how to set it in hiveos?!

Hello
on first page you have the link to github where it's explained (appart from the mentionned packages to install where he doesn't give the command "apt install packagename"

I did it on hiveOs through the "shell in a box".

Update:

Decided to release a Winblows supported version.

I've tested it on 2 systems with Latest adrenaline version (one with a Vega gpu, the other with a 570) and confirmed working.

Check OP for link.


Please post results here. That's all i'm asking Smiley

Cheers guys!

I walked the long road with finding mmio address, reading and writing to the appropriate offsets, and you just.. used an asus .dll that has everything that's needed, with a signed kernel driver..
Well done Eliovp  Grin

Tested on VII.  tool reports timing modified.  Got a very light boost on HR.  Thanks.
Is there a reset command to revert back to original timings?

@Eliovp, once again thanks for your efforts here getting it onto windows. Much easier for traditional Vega Users with PPTs and Overclocking tools to really test the limits of your tool!

For my part, I'm getting pretty decent results on ETH; Reference Powercolor Vega 64 on latest Adrenalin 19.3.3 drivers.
Thanks to Windward for getting me started on values for parameters.

https://i.imgur.com/6bedvOO.jpg

Given the generosity of Eliovp in even making this tool available, I'm not gonna be the guy that takes and doesn't give back.

For those curious, here's what I put in a batch script after I honed in on parameters.

(PATH to folder where MemTweak is stored)\WinAMDTweak.exe --CL 16 --RAS 30 --RCDRD 14 --RCDWR 14 --RC 44 --RP 14s --RRDS 3 --RRDL 5 --RTP 5 --FAW 20 --CWL 7 --WTRS 4 --WTRL 9 --WR 16 --WRRD 1 --RDWR 19 --REF 17550 --MRD 8 --MOD 15 --PD 8 --CKSRE 10 --CKSRX 10 --RFC 244

Run before starting the miner. For some reason, injecting the timings when mining would crash the miner if FAW>17, but FAW>17 is okay if injected prior. Also, RC<44 led to incorrect shares being found. No guarantees of stability... I was simply looking for accepted shares w/o rejects in short runs. I need to read up as well on compatible RAM timings... lower RC seems to drive HR the most.

Happy to answer any Q's; also, memclock was 1107 and was using PhoenixMiner4.2c

Eliovp, great work on this tool.  Here are some of my results:

OS: linux/Ubuntu 18.04
miner: teamredminer 0.4.3
card: Vega 64 air cooled (MSI air boost OC w/ samsung mem)
core clock: ~1150Mhz
mem clock: 1100Mhz
timings modified: --rp 10 --rc 44 --rfc 300 --rrd 3 --rcdrd 12 --rcdwr 5
hashrate w/ stock timings: ~19.5kh/s
hashrate w/ new timings: 21.36kh/s

Unfortunately I don't have power readings from this rig, so I'm not sure how much the power usage increased with the new timings.
I think the card can be pushed more, but I don't have the time to keep tuning at the moment.

Read that before. Don't want to go through installing visual studio just to build this..

I tried todxx timings in Windows teamredminer, turtle algo and working well so far on 6 out of 7 reference Vega 64s. One vega reports dead with the timing, and I believe it is the "rc" value causing it. Will look into these further. Thanks for the start!

Has anyone successfully improved hashrate for any cryptonight algos with VEGA56/64, win 10, latest AMD drivers?

what about cnr settings will it be, sir
I just apply this to cnr on my vega56 hynix memory,  it was crash when startup

only way to run it was set core 1150  memory 800  850mv it will work but the hashrate was low, olny 1500h/s

before it was able to run 1481@875mv 960@905mv and got about 2000h/s without errors and stable

Hah, it works. Thanks for the tips for getting it to start properly.

Started with todxx's timings and yup, went from ~19.5 to 21.3+. Nice. I'll take that. Let's leave it for a while and see if it can sustain the timings in the long run.

(PATH to folder where MemTweak is stored)\WinAMDTweak.exe --CL 16 --RAS 30 --RCDRD 14 --RCDWR 14 --RC 44 --RP 14s --RRDS 3 --RRDL 5 --RTP 5 --FAW 20 --CWL 7 --WTRS 4 --WTRL 9 --WR 16 --WRRD 1 --RDWR 19 --REF 17550 --MRD 8 --MOD 15 --PD 8 --CKSRE 10 --CKSRX 10 --RFC 244

Adjusting CL does not affect hashrate directly for me at all. As higher CL is more stable, I'd leave it at stock 20.
Another remark is that you set RCDWR the same as RCDRD... it gets faster if you decrease it.
But the max I could squeeze out from it is 51.5 @ 1100MHz with my mods, without it it was a bit less.

Edit: I'm on 18.6.1, maybe 19.3.3 is faster?

Edit2: FAW=20 does not work for me. it's unstable.
