Topic: AMD Mem Tweak XL - Read/modify timings/pp/straps on the fly - page 49. (Read 58892 times)

Just start a command prompt and run it within? Or run it but add >file.txt after and it will output to a file.

Anyone having some good timings for Radeon VII? I'm thinking of Cryptonight R algorithm. I like to run my Radeon VII at low core and memory but I'm getting lower hashrate than my Vega 56 at same clockspeeds...

I use th --current command to find current values. It loads all values and then closes. How to get it to stay open. I add pause but still no good.

This is a great tool, thanks to the author!

I finally got my Vega 56's (v64 BIOS) stable running the HBM at 1100MHz by increasing the CL to 21. I am using SRB 1.8.2 mining Monero (CNv4) with the following settings:

Core: 1447MHz 0.900V (0.870V according to HWiNFO)
Mem: 1100MHz

Timings: --CL 21 --RP 12 --REF 15600 --RC 45 --RFC 244 --FAW 20 --RCDRD 12 --RCDWR 8

4 cards averaging 2060H/s each, total system pulling 820W from the wall.

EDIT:

Testing now with 0.850V core voltage (0.825V according to HWiNFO) total system power 740W.

Lowered --REF to 7800 due to incorrect share popping up, hashrate dropped to 2040H/s per card .

Yes.

I tried stock timings from V56 on V64 bios and memory set at low freq.
But there are 3 values in it that cause instant crash of gpu.
Rddata, wrlat and rc 39
The first two seems to be unable to change on the fly. And rc is simply too low because there must some unrevealed parameters in the timing strap that also needs to be changed paralelly.

However without these 3 params the v56 timing gives the same hashrate in CN algos at 925MHz as the stock timing at about 1050M.

Anyone got into this?

Also in the jedec pdf the mode register bitmaps are different than the structure in eliovp's tool. So it would need a bit of trying to find the missing values.

as in these?

--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

Try my timings if you want to run ethash 51+ mh.
pbfarmer's timings are better for CN algos.

Also you may have to increase core clk to benefit from faster mem.

just thought i'd share what i've done with this with the hope it helps others (or me)

have 3 vega's mining ETH on my rig (have a mix of rx470s, 480s and 570s, using phoenix 4.1c, amd driver 18.5.1 but will try 19.2.2 soon)

all vega reference 56's flashed to 64.

using wattman to adjust settings
windoze 10 1803
gpu 852mhz @ 0.825v
mem 1085mhz @ 0.825v
power limit -40%
(GPU only power draw in GPU-Z is 116w)

previously getting ~43.4mhs

now getting ~44.1mhs with using "winamdtweak --i 6,8,9 --rp 12 --rc 44 --rfc 250 --rrds 3 --rrdl 3 --rcdrd 12 --rcdwr 5 --CL 19 --RAS 28 --REF 15600"
*no change in power usage (checked with hwinfo via my corsair rxi psu's)

woooo this is yuge

does it only work on vegas with samsung at the moment or does it work with hynix versions too?

Ok, now after 16 hours of running, i can say: superb! 

Reference Vega 56 (64bios) at 20.7 kh/s 1280/870 1090/900 ODT L20+20 (TRM)
Asus Strix Vega 64 at 21.32  kh/s 1280/870 1090/880 ODT, L18+18 (TRM)

Driver 18.6.1., GPU temp 66 C (have problem with small space for rig, so results could be even better), power for 3 Vegas + 1 RX570 from the wall 710W.

So after pissing about for 3 days I've gone back to stock Vega 56 bioses.

The Vega 64 bios on my cards did increase the hash but at the cost of way more power and hash drops 20khs and 1.2kw from the wall

Fine tuned the my cards on 56bios to 19khs without timing, And 20khs with timing pulling 950 w from the wall. Pool hash rock solid now aswell

Ohhhh i did not know about the "releases" button. 

Thank you!

Dude, seriously?
Go to the github linked in OP.
Click on "releases".
There you go. Your files are there.

That doesn't take two fukcing hours.

WHERE???

I have been looking for the binaries for over 2h now, im starting to lose my mind.

Just download the windows binaries from releases.

Can someone please tell me how to get this running in windows?


# Build (Windows)
  - Clone repo
  - Launch VS Project
  - Build!

I downloaded or "cloned" the files from github.
I deciphered "Launch VS Project" to download a Visual Basic program, (install a bunch of stuff i dont want) and open a project in Visual Basic.

And i have no clue what to do now, cant find any"project" or "Build" option.

On my 6 card rig FAW 12 instant crash, but on my 5 card rig it's running good for the last 2 hours. 30 min avg. hashrate increased from 10641 H/s to 10720 H/s @ CNR.  Less than 1% but its for free
Now more than 10% increase from stock values. 9600 H/s --> 10700 H/s.  11.46% for CNR which is not the most memory intensive algorithm.

So Now

Do research about profitable with this Great Tweaking of the Decade,

ETHASH or CNR ?

So, CNR must be perfect in tuning, then hashrate got reward in good shares

Beside that, Pool eficiency must be good, so mining profitable
