hi i have vega 64 i got hashrate 98 Mh/s , Core 1470/mem 970 , Core undervolt: 970 can you help me 
@alireda - If you are using a different miner, switch to Team Red Miner.
@rakjung23 - you should flash the 64 with a 56 bios. More hash, less watts and more stable and it only takes like 5 minutes to flash a 56 bios. If you have never flashed a bios this is a good guide to do it safely in HiveOs.
4 & 5 on this rig are 64s flashed to 56, just installed a MORPHEUS II cooler + 2 120m Noctua fans on GPU4, at 200Mh slightly lower temps than my Rog Strix. love it! might buy one more of those for GPU 5.

Hello. Who tried to play with memory strain? What results have you been able to achieve?
Wow, that is an admirable rig.
I’m wondering what you have SocMhz set to? On my 5* Vegas I have always been able to get 180 Mhs @ 129W with core 1300, vdd 850, SocMhz 850, MemMhz 847.
On some I can get away with vdd 825, while others can only do 170 Mhs but use 119W.
thanks YOU brother

Hello everybody.
(Google Translate)
first of all I’m new to mining.
I have the problem that I don’t get a good hashrate with my vega.
It is not BIOS flash to a 56 and I don’t want that either because I have no idea about it. and don’t trust me
have to do it i 1 png (new youser)
what is my problem?
do i have to make a bios flah?
EDIT:
i did it!!!
now it’s a Vega 56!

hey man, can i know your BIOS Settings,
2 of my motherboards give me crap each time i add a 4th vega 64 flashed with 56.
Are you on Gen 1 or Gen 2?
Would be helpful if you specificy your motherbaord.
And list down all your bios changes.
I know its my bios as both of them would give me dead gpu each time i add a 4th one. but with 3 vegas only it runs smoothly.
last two I built
mobo: TB250-BTC BIOSTAR
mobo: PRIME Z390-A ASUSTeK
I boot, then update the mobo bios under advanced setting, then set to Gen 2 and Enable 4g Decoding.

Did you mod bios? Did you use amdmemorytweak settings? Did you do both? Which settings did you use?
I have 1 Vega 64 Sapphire nitro + (bios mode to 56 Sapphire.RXVega56.8192.171218)
HiveOS is on an SSD. and connected on LAN
Every 5-10 hours the rig goes offline. like this:

all time it goes Offline in a few hours…
do you have any idea? maybe it’s not because of the overglocking?

A bit unstable (i think) the hashrate… is around 175Mh/s - 196Mh/s +/-
Because i have a 1080ti (nanopool - nanominer) and the hashrate is always around 103.4Mh/s - 103.6Mh/s
Try and see if stays Ok…
I’ll try it. I will get back to you later. Thanks
I’m gonna find you, and i’m gonna marry you. You handsome fella!
Thank you very much man!

hahaha, saw you post your getting a couple reference 64s soon…
These two are Reference Vega 64s from Sapphire and XFX flashed to this 56 bios
GPU 4 (Sapphire 64, temps are low because I installed an after market cooler)

Sorry to ask…
I have a sapphire vega 64 nitro +
reference 11275-03 with 240w
I can use that bios to flash my card?
I noticed the same with the latest hiveos version; I downgraded it to one version lower and it is stable again 24/7.
New to mining and out of all possible gpu’s you start with Vega’s, that’s very brave 
In my humble opinion, they are amongst the most difficult gpu’s around, and they’ll take a lot of your time to finetune, but if you love to do that, these are the right gpu’s for you 
Luckily there are lots of great people in this forum that do a lot of trial and error and share those results; reading these Vega topics from beginning to the end is very recommended!

I share that opinion! great people!
the rig was offline again after 6h …
try it now with windows that I can exclude hardware problems (CPU, RAM).
and yes i do this out of pure interest in the thing, not for profit 
if it works I’ll try another Hice os version.thanks!
Edit: Tweaks on WIndows much more complicated… but i works for now
