Does anyone here knows if i can flash a 56 bios into a 64 liquid cooled vega?
I don’t know if it would work. I don’t know if liquid cooled 64 vegas have bios switches(dual bios).
There are no liquid cooled vega 56’s. So i would need to flash a reference 56 bios. I’m afraid it would brick my lc.
Any thoughts?
Yes. Itll be easier flashing in hiveos, windows was a pain. I used the reference AMD bios for vega 56 aircooled. Runs well but definitely more watt usage than stock air cooled. settings vary but im using 1465 core 915 VDD and 925 mem for 196 MHs at 148W software (probably 170W wall). Strap same as OP at top of this post.
How can I lower these values?, they are so high. Temperature… well, I have fans, I don’t know why they are not lower, but the load %…
Those % are related with fans %, right?. As I lower Fan% and that value goes lower.
A little bit better now at least, placing the fan in another angle:
Confused on the question, but left is memory temp and right is fan speed. My 2 cents is you can replace fans but you cant replace memory, so I opt to run fans high

Yeah, so I can increase Fan% or put more fans in my room. Gotcha, thx!
That worked great! I’m now setting at 181 mh, while pulling 147 watts. I was able to get it to 171 mh at 118 watts though. I might pull it back a bit to save on the electric bill haha. Still very impressed with this card.

Yours is a vega 64 watercooled too?
Yes it is

Careful as ive found vegas pull a LOT more at the wall tahn they say. 140 is around 175 or so
Funny enough my strix hynix does better than my msi airbost…lol…
im on the gold coast so hr south of brisy… gona be a mission to move all the rigs here ?
Hi Silver, I have the same card 4 nos, The card detects then goes offline without temp and percentage when i boot it comes back up . Please help.
Using these settings, my vega 56 reference card drops to 33mh… Not sure why? If I flash it to 64, I can get up to 186mh stable at 150v, but 56 seems to drop the hash significantly.
Hello. 580 on Hynix give 63Mh, but 470 on Elpida easy give 66-67Mh (as fact this 470 may give 70Mh, but rig in my bedroom, i don’t want speedup coolers over 50%). All card flashed one click timings in Polaris Editor!
33 MHs is typically the unstable card result. Try the memory timings with different overclock/undervolt settings

Next question is… once I find the right BIOS for this “Sapphire Radeon RX VEGA64 Nitro+”, how do I know which overclock and Strap should I use?.
Any of you have a “Sapphire Radeon RX VEGA64 Nitro+” flashed to Vega 56?
EDIT: I used again @Smining570 data for a Sapphire he has and… bingo

Does anyone have good settings for Gigabyte 64 flash to Gigabyte 56? It is the strangest Vega I have. Unlike other ones, they only way to get hashrate to rise is to lower both clock and voltage. I lowered to about 1300 MHz and 800 mV while holding memory constant 900 before it got unstable and it settled around 175 MH/s at 165 W. Pretty abysmal comparatively. And yes, I verified this odd relation on the pool and it does hash what it claims. Also have 2 and both behave the same.
Is it a reference (1 blower) or aftermarket (2 fans) ?
I have one aftermarket type since recently and also struggling to get it running like the others. At first I updated to the F6 bios, but it was capped at 190W and therefore the hashrate was limited. I’ve found another F6 bios that goes up to 210W but decided to flash the FA1 which goes up to 222W. The card doesn’t reach the cap anymore, but I’m still on summer settings with :
core 1340
vdd 860 (still in process of lowering step by step)
mem 847
soc 860
amdmemtweak --RC 36 --RP 11 --WR 14 --CWL 8 --FAW 12 --RAS 20 --REF 65535 --RFC 248 --RTP 4 --RRDL 6 --RRDS 3 --WTRL 9 --WTRS 4 --RCDRD 10
This gets me around 183MH/s for 193W

Don’t use the same settings as you use for 64 on 56.
Can you tell us which settings exactly you have applied? Which card is it? And which bios have you flashed?
They might help for a few °C, but don’t expect some extra household fans to lower temps a lot.
You need to evacuate the hot air outside of your house.
And what lots of us do during summer is running at lower clocks so voltages can get lower resulting in lower wattage meaning lower heat. This off course also means lower hashrate, but the cards might live longer too.
Just read on another forum that the gigabyte cards report the ACTUAL consumption, whereas the other cards report the lower amount. This makes more sense now, will tweak like other Vega’s. It is an aftermarket 2 fan model.
