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

Hello guys !

I've got 6 Sapphire RX Vega 64 Nitro+ and I would like to knows if someone had test wich parameters is good for this card.

I'm using Claymore V15 for mining Ethereum (ETH) only

I've already test BuriedONE parameter in his video but I've got overclocking errors

Thanks !

Nico

I use the following for ETH on my Nitro 64s - maybe not ultra best, but close enough:

Code:

--RAS 28 --RCDRD 12 --RCDWR 5 --RC 44 --RP 12 --RRDS 3 --RRDL 3 --REF 15600 --RFC 248 --FAW 14

for a couple cards w/ weaker mem chips/controller, i use a slightly less aggressive profile:

Code:

--RAS 32 --RCDRD 14 --RCDWR 6 --RC 44 --RP 12 --REF 15600

Hello pbfarmer !

Thanks for your reply !

What kind of profil do you use in Wattman ?

Nico

I don't use Wattman (or even Windows, honestly,) but basically I lock my core state to p0 (850Mhz) by disabling all states above that, while setting my mem clock to 1107 (p3). Then set your mem p3 voltage to whatever is required for your card - should be somewhere between 800-850mv.

This should get you to ~50MH/s for a Vega64.

Hello guys !

finally, I can't do it.. I'm going crazy, i'm giving up !..

Can't reach a right profil without "Incorrect ETH Shares" and same without tweak..

I don't understand how is it possible... I've got 6 Sapphire RX Vegas 64 Nitro+ and I cannot have a profil around 50-51 Mh/s without errors...

I've already try this :

Conf 1 :

GPU :

- P0 : 852 Mhz / 800 mV
- P1 : 1175 Mhz / 900 mV
- P2-7 : Disabled

Memory :

- P3 : 1100 MHz / 900 mV
- P0-2 : Disabled

-> Incorrect ETH Shares

Conf 2 BIS :

GPU :

- P0 : 852 Mhz / 800 mV
- P1 : 1075 Mhz / 850 mV
- P2-7 : Disabled

Memory :

- P3 : 1090 MHz / 900 mV
- P0-2 : Disabled

-> Incorrect ETH Shares

Conf 3 :

GPU :

STOCK

Memory :

STOCK

-> Crash then restart !

Conf 4 :

GPU :

- P0 : 852 Mhz / 800 mV
- P1-7 : Disabled

Memory :

- p3 : 1107 Mhz / 837 mV

-> Settings won't apply in Claymore (I've got 44 Mh/s)

WTF is that ? I don't understand what's wrong ...

My config file with Claymore :

Quote

setx GPU_FORCE_64BIT_PTR 0
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_SINGLE_ALLOC_PERCENT 100
@echo off

If someone can help me to reach a good profil it very helpful or i'm gonna die haha
