I'm also stable with the same timings and --rfc 250 which gave me an additional boost. Modified timings would be
Code:
--rp 10 --rc 44 --rfc 250 --rrd 3 --rcdrd 12 --rcdwr 5

Thank you for the info.
I will give it another go.

BTW for current version '--rrd 3' should be replaced with '--rrds 3 --rrdl 3' otherwise it won't be set

Edit: Tried it again on my ref V64 Samsung, but same... it crashes after about 1 min.
BTW what's the point in such low rcd if you don't set ras accordingly?

Is there any settings for cnr

Stock Timing : 4530 h/s
Todxx Timing : 4800 h/s

Is that working stable for anybody?
that rcdwr is very low. GPU crashes in a few minutes for me.

Yeah it crashs after 1.5 hours. Also curiously it crashed on the best silicon i had  Huh Not the weaker cards.

I'm also stable with the same timings and --rfc 250 which gave me an additional boost. Modified timings would be
Code:
--rp 10 --rc 44 --rfc 250 --rrd 3 --rcdrd 12 --rcdwr 5


EDIT2: here we go, increased --rp from 10 to 12 and that weaksauce-GPU is doing 21+ kh/s like his little buddies. Ka-pow!


BTW for current version '--rrd 3' should be replaced with '--rrds 3 --rrdl 3' otherwise it won't be set

Results:
Cards : Vega 64 (aircooled, reference, samsung)
Miner : SRBMiner 1.8.3
Algo : Cryptonight litev7
Clocks : 1408/1107/875 (ODT)
Actual : 1354/1107/850 (HWinfo)

Stock                                                                                                         : 4530
Todxx               --rp 10 --rc 44 --rfc 300 --rrd 3 --rcdrd 12 --rcdwr 5              : 4800 crashes in 10-15
Based on above --rp 12 --rc 44 --rfc 250 --rrds 3 --rrdl 3 --rcdrd 12 --rcdwr 5 : 4870 stable

At first, happy with Windows Edition, tweak many value as others, CL low - crash, RFC high - crash etc

But with others correct Value, doesn't change anything : ETH 44-45 Mh & CNR 2050 hz

So, someone done with 51 Mh ETH Huh True ? How about Windows ?

Gigabyte rx vega56 gaming hynix   trtl:19.75

WinAMDTweak.exe --rp 15 --rc 34 --rfc 156 --rrd 3 --rcdrd 18 --rcdwr 3
Vega 56 - Hynix.

algo cn-trtl.  got a boost of approx 1.2 Khs

Code:
--ras 22 --rp 12 --rc 34 --rcdrd 16 --rcdwr 10 --rtp 5

Holy shit! Thanks!
This hynix bastard can do 19.9kh/s with stock bios and 940 mem clock! No need for mem voltage and clock boost via v64 bios ))

winamdtweak --rc 34 --rcdrd 12 --rcdwr 5 --rp 12 --faw 16 --rtp 5

Update. --rp 12 to tight for my card => dead in some minutes. went to --rp 13 without performance lost
Upd.2 --rc 34 seems stable but not needed. --rc 36 gives the same 19.9kh/s
So, my current settings for long run testing are: --rc 36 --rcdrd 12 --rcdwr 5 --rp 13 --faw 16 --rtp 5 --rrds 3 --rrdl 4

Have you managed to find a good value for RAS to go with the low RCD?

I ran some tweaked timings overnight but the hashrate on pool is not living up to expectations. Some GPUs give hardware errors, some just seem to have substantially lower hashrate on pool. Trying to loosen up some timings... but this is going to be a long process.

OK... I'm revealing my secrets. Smiley
Here are the formulas straight from wikipedia, not hard to find.



If you check ras, rcd, wr, rp, rc you can clearly see the formulas were used.
These values are not hocus pocus. They are calculated according to specific rules.

So if you change ras, you should change rc too and vica-versa

I changed a few things in the timings from todxx/kerney to (hopefully) improve compatibility with more air cooled Vega 64s w/ Samsung:

--rp 12 --rc 45 --rrds 3 --rrdl 3 --rcdrd 12 --rcdwr 5

This should also work for bios flashed 56 -> 64 w/ Samsung. However, I noticed hashrate drop overnight. If anyone has ideas lmk.

For Vega 56s w/ Samsung and original bios:

--rp 12 --rc 37 --rrds 3 --rrdl 3 --rcdrd 12 --rcdwr 5 --ras 25

Also based off of recommended settings from todxx/kerney, changed "rc" to work with Vega 56 w/ Samsung and original bios. Does not work with Hynix.

Edit: added --ras 25 so that RC = RAS + RP

Ah thanks, that's actually what I was looking for.
My days of tweaking DDR timings are several years back... Fun to experiment with HBM actually!

One important thing though: observe the hashrate on the pool. Whilst miner hashrate might look higher, tight timings will decrease effective hashrate if your GPUs can't cope. TRM will show you that figure on the column most to the right. Have a look, you might be surprised.
