AMD Mem Tweak XL - Read/modify timings/pp/straps on the fly

[fr4nkthetank]

Just try claymore with -ref option set to 10 or 30 or something, should help a bit if straps dont work

I have flash this card with a Sapphire Vega 64 BIOS :

https://www.techpowerup.com/vgabios/205360/sapphire-rxvega64-8192-170914

But this BIOS is for Samsung memory.

Is there a Vega 64 BIOS for Hynix memory ? Or I can use this Vega 64 ROM ?

Did you have some good settings for a good hashrate ? I already have a Vega 64 in my rig and it's very stable with thoses settings :

https://www.youtube.com/watch?v=xJWWEecwZoU&ab_channel=BuriedONE

Phoenix-ETH report 51 MH/s and 160W

I hope I can get close to it with my vega 56.

Thanks.

In short, try the following for a 50-51 MH/s setup:

1) Set clocks to core clk 1075 MHz, mem clk 1107 MHz, voltage at 850
   mV. Your card may need to clock down the mem clk to 1050-1080 MHz
   to be stable with no hw errs.

2) Use the following modded timings:

   --CL 20 --RAS 30 --RCDRD 14 --RCDWR 12 --RC 44 --RP 14 --RRDS 3
   --RRDL 6 --RTP 5 --FAW 12 --CWL 8 --WTRS 4 --WTRL 9 --WR 14
   --REF 17000 --RFC 249

3) Hopefully it runs stable and you should observe a hashrate around
   50.5-50.9 MH/s. If your GPU can't handle the timings, you need to
   relax them to less aggressive variants available in the AMD mem
   tweak thread on Bitcointalk, or come join the TRM discord for
   further suggestions.

4) For better efficiency (but lower hashrate), tune down your core clk
   and try to further lower voltage while remaining stable.

5) We reiterate: _blast_ your fans and monitor your HBM temperature.

thanks man your setting helped me to get it at least stable at 50.8 mh/s after 3 days of trying but still I'm on around 1100w per 5x vega64 system I think it can get lower

i just saw this project and it looks amazing..

Anyone knows if it is possible to use with ETHOS? Also, is there a step by step guide to install and use it?

power consumption depend on temperature, if you manage cooling core to 40c surely will get 20%+ more efficent and you will able to lower voltage
1100w is normal for 65c gpu at 0.86v

[juicyM555]

hmm interesting, I will try to cool it down more.. also I found out about XHV mining wich consumes less power and give more yield ass well these days (ach I hope we will see ethereum around 500$ till the end of year  ) so now I'm looking for new timings I managed to get 2200 hs, 160w per gpu, (user livada timings ras 28 rcdr 12 rcdwr 5 rc 44 rp 12 rrds 3 rrdl 3 ref 15600 rfc 246 faw 14) one small error I get with TMR that always my gpu0 (tried switching gpus) hashes like 10% less, don't know why i'm going to try different miners as well, and maybe give a shoot to hive os again and play with agressive undervolting, dpm etc... will post some low power cons setting when I find the best one

[juicyM555]

Could you guys please share your hashrates for vega 64 cryptonight_heavy algo?

[wielaa]

Hi Guys,

I was browsing posts in topic and I am interested into how ppl get these 900w with 6 vegas?

My setup is 5x vegas64 (samsung) flashed to 56

I got 273MH/s with 985 watts from the wall using wattmeter this is around 54.5mh/s from the card. So where is the trick?

Cheers

I'm also interested, but maybe they taking wattage from gpu-z, heard few users saying u can't get much below 170w if you want to keep stable 50+ hashrate and I think so...
Could you please share your settings? these are quite good results ur getting also what 56 bios did you flash into because I didn' know which to choose and got like -10w only

real? and you wont better? this is verx nice HR for this power.

Send 1 SS for this Hr  and pls send your setings. Owerdrive and Tweak.

cryptonight heavy (xhv) vega 64 ref samsung, 2.15khs 160w per card, pretty stable

Hello guys, your help would be aprreciated 

I have few vegas64 reference samsung memory on me (gigabyte, powercolor, amd) and unfortunately have a hard time setting them to be as efficient as they could

First I tried amdmemtweak with hiveos but couldn't get the results I wanted not even close, still was about 250w from wall (in this post all wattage will be from wall), so I switched to windows 10 and started getting more interesting results as I went through almost every page in this thread (thanks for sharing your settings btw)

Bassicaly I'm aiming on low power consumption because my electricity isn't that cheap here - 0.16$/kwh

These are my best results

--CL 20 --RAS 30 --RCDRD 14 --RCDWR 6 --RC 44 --RP 12 --REF 11700 --TRFC 260
https://imgur.com/a/bPlLOdi

- I was getting 47.2 mhs, 175w draw, after 3 min it always drops to 46mhs but it's stable

I wanted to get lower with power consumption as I found out one guy in our local forum posted he is getting 42mhs with around 100w power draw on his vegas 56, so I flashed one of my vega64 to 56 bios and applied the exact setting as he did, the hashrate was exactly the same around 42mhs but i got only to 165w

Here you can see the settings
https://imgur.com/a/M81meD4


I can see some users getting very nice results with 50mhs+ and low power unfortunately the discussion ended

would someone please be able to help me out with some vega 64 timings and clocks and maybe ppt tables to get power usage below 200W at wall? been getting 48mh @200w from wall from each card, i imagine i can do better.

Settings in pic run ~168w/GPU including idle ATW (120v, 1600 plat PSU).  amdmemtweak params are --RAS 30 --RCDRD 14 --RCDWR 6 --RC 44 --RP 12 --REF 11700 --RRDL 4

Thanks mate ill give them a run. im on windows though and dont think i can get voltages down that low without powerplay tables? think its capped at 900mv.

You can use ODNT to easily create a PPT similar to my clocks/voltages listed on the right.  Only difference is that you may need to use mem P2 set to 1028 (and lock out P3), in order to take advantage of the power savings of a reduced SOC clock.

Btw, if you really want to get crazy, there's been a lot of noise about flashing a 64 w/ a 56 BIOS (yes, the reverse of what most people have been doing) to get higher hashrates at lower power.  Not sure which models this actually works for tho, and haven't tried it myself... yet.

i'm getting 54Mh (samsung) and 50MH (hynix). 930W on the wall for 6 vegas (all flashed 56). 900W on the wall, plat PSU.

I will study more and want to play with core and mem control more but I dont understand it fully yet and always when I change it, it lowers hashrate and draws more power  , I saw some users setting OD_SOCLK and also values for OD_SCLK, OD_RANGE under linux, I also downloaded ODNT but can't see these settings there also when I apply first amdmemtweak then odnt the miner just won't start (im using TRM) ...  Could somebody please share their low power cons setting for vega 56/64  or advice me which values shoud I try tweaking , thank you very much

Unfortunately, this will never be efficient / low power as the 1107 mem clock also requires an 1107 socclock, which eats power.  That's why i run at 1028 mclk, and why flashing to 56 bios is even better.  Besides dropping your actual mem voltage ~100mv, i believe the 56 bios also uses a different set of timings which make the 900-950 mclk range quite performant, which means socclock can be run much lower too.  (Of course, most of those timings can be replicated w/ amdmemtweak, tho not all afaik.)

Tested that and yes I get 54 mh/s in TRM in miner console. But the pool still sees around around 47 mh/s, even after 48 hours of running.
Seems like an inflated figure on TRM side.
Guys can you check/concur this?

[Pericle13]

report back that figures have balanced out in the pool also.
It needed more days to reach the correct average I think
