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

[Mashy81]

whats the real difference between trm .4.3 and .4.4.  I know obviously the intensity deal 14*14, instead of the +/-.  I can make thinks work great in .4.3 but in .4.4 my hash rate sucks ass

Using the *  instead of + activates a different vega mode which complements the memtweak tool.

Hey guys,

getting error message while trying to run --current

Failed to load EIO.dll

Are you using SRBminer? It blocks it ((

Simply use the --disabletweaking parameter and you can use ElioVP's tool with it.

Hey dok, will you be giving us non-bios modded Polaris types a hashrate boost in your next release?

That's the plan, maybe not in the next release but yes

I have now run ~72 hours w/o any issues with 24 Vega64 GPUs(good and bad ones) mixed in 4 separate rigs ... CNR with core 1407Mhz /860-970mV , Mem 1080-1100Mhz/860-970mV.

I would say this is pretty stable setup. Pool side 24h avg hashrate fluctuates in the range 54,1-54,4 kH/s

--CL 19 --RAS 28 --RCDRD 12 --RCDWR 5 --RC 44 --RP 12 --RRDS 3 --RRDL 3 --REF 15600 --RFC 250

I am happy and have in my mind... "dont touch when things go smoothly".

That’s an insane voltage range, and I can’t fathom how 970mv could possibly be necessary. Between 9 64s and a flashed 56, I run avg 834mv, none over 850, for similar clocks/timings.  That puts me @ 178w per GPU at the wall.

At 970, you’re running at least 35% higher power, meaning over 240w per card.

It sounds like you have some ppt issues or something, maybe you’re running your SOC @ 1200mhz unnecessarily (it should be 1107 @ your clocks.)  Although, even then, you prob shouldn’t need much more than 925mv.

Oops... I made a quick check with HWtool and yes... I really have SOC max @ 1199Mhz. I have used the Hellae 920mV PPT and then adjusted with Overdrive Ntool the Core P7 and Mem P3. I havent touch the SOC. After memory timings my rigs are pulling like 1420-1500w from the wall per rig. My rigs run like 150w w/o GPUs and after OverdriveNtool the wattage is ~250w before the miner starts and all the GPU led lights are fully on.
This sounds to me like 1270 to 1350w with 6 GPU and on avg. like 210 - 225w/GPU. :O

Thanks for pointing out the SOC. I need to drop to 1107.

When I tried to scribble down a new Vega tuning guide to include in the TRM 0.4.4 release, I was debating if I should have mentioned this or not. I opted not to, that text was long enough already anyway.

However, I know more than a few skilled and knowledgeable Vega tuners that ALL have been stuck with old PPTs from the fall of 2017 (brnsted, Hellae) that for some reason all have 1200 for SoC. At the time, I guess it was considered highly beneficial for stability. Fast forward a few years to times where you don't make $10/day/Vega and power draw is a crucial part of your setup, this trade-off no longer holds.

In the common Google sheet (https://docs.google.com/spreadsheets/d/1-rhYsaRXO1ahk3PyrEgT9gXzs7ImAzh-sbqtgwy8HQg) used for PPT tweaking you can edit the SOC clk value but guess what: it doesn't change any nrs in the PPT, the cells aren't connected(!!!). You have to change the SOC clk value in cell AE26, then manually copy cells AG-AI:26 to T-V:11. You can probably guess why I may sound a little pissed off  .

Yeah.... I fixed my file so that these cell are now connected. Will test today what kind of mV I can get with 1107Mhz SOC.

please post the PPT for reduced SOC.Thanks in advance.

My initial findings.... so far stable rig with no hash rate drop(tested only one so far). 
Power draw from the wall dropped ~200w 
(1450w -> 1250w). So if my rig w/o GPUs pull like 150w it means that 6xVega64 are now pulling like 1100w or ~185w/GPU.

Grate tool, thanks, but my 4 vega crash after while, I wonder what to use in pstates? Maby there is the fault?
[https://ibb.co/qrXvT7d]https://ibb.co/qrXvT7d

Voltages are way higher than all of my vegas. Maybe drop your core down. But that shouldn't be the problem at that voltage
Maybe heat is the issue.
Or memory tweak options you have don't work with your cards.
Are all cards.the same?

It's 2 vega 56@64 reference watercool and 2 vega 64,asus,nitro,samsung memory all. I try lower settings than eviolp suggest but for some reason my rigs crash after while, I make changes on the fly, is it possible to crash from this? I use srb miner, Iam confused what's fault.

Don't use srb miner theres your fault. Use team red miner 4.4  they are about 10-15 higher hashrate.
They are the best public CN miner. Lowest power consumption also

lower settings = tighter strapes...you have to use higher settings

After two attempts with team red miner I got one crash and one dead gpu.

Red team miner 4.3 gives a better hash, which driver to use?

"HOW"
4.4 is 15% better hash for me and others, you must de doing something wrong

Timings were published for 51.5mh around page 8 by N2DCRYPT

and also by me here
Try them.

You may have to use different straps for each GPU. Also if you really want anyone to help, more information is key, or maybe you don't want help and it is just a statement who knows.

Thanks Zorg33 !

btw, how to get timings for different memory for 470/480/570/580

[zenrog]

Does anyone tried with rx580 on ethash?

[Mashy81]

Does anyone tried with rx580 on ethash?

I beleive people have tried but it is not as good as a good vbois flashed onto them.

[VasilyS]

Does anyone tried with rx580 on ethash?

Yes, I tried. It is useless if your cards have modded BIOS. It may be good for GDDR5 cards with not modded timings.

[SamAlackass]

Seems to be working on 18.5.1 too if anyone is interested!

[Art Gar]

Seems to be working on 18.5.1 too if anyone is interested!

very interesting. if you can please share your results. rx580 gddr5 interesting. All internet timings is cool of course. but when timings I can tweak myself - that is cool. Please share your playing to start for noobies.. Thanks for early.
