Could be your power supply or riser being old!!
No, of course not. I use these cards in gaming PCs. As I said in my previous posts... Not possible to use these cards even with 800 MHz memclock so it has to be lowered in bios of the card directly to 700 MHz. And I am not able to find the tool to change those values in the cards so the value is saved in the card itself.

Use Amd memory tweak and ONT are the best combo!
Cool, I found Amd memory tweak but what is ONT?
Guys, could anyone help me with this to modify the bios? I will pay you. Hi,
ONT - Overdriventool
On my AMT i have this for vega: (working flawless 3 years)
https://ibb.co/WygKs8T
Best Regards
And is it changed directly in Bios? Because I need to decrease the max memclock from 800 MHz (default Vega 56) to 700 MHz... For all my Vegas because in gaming (after more than 5 years 24/7 of mining) they are incredibly unstable. As I tried Overdriventool - it did not change values in card's bios unfortunately so this software would have to be installed on each PC (which I don't want). Do you have any idea?
yeah the ideia of that is changing on fly the straps
Just test it

Guys, could anyone help me with this to modify the bios? I will pay you. hello guys. I have a lot of VEGA 64 LIQUID cards, unfortunately they are not able to handle the stocks VRAM frequencies (945 MHz). I had to force flash VEGA 56 bios (800 MHz), some of them are working, but some need even lower VRAM frequency 700 MHz. If I set it in MSI Afterburner to 700 MHz, everything is working. Can you help me to find the way how to modify BIOS directly to set 700 MHz so no overclock software is needed?
Is there any app useful to mod this frequency into VEGA 56 BIOS to 700 MHz? Thanks a lot for your help! Lukas

Are you using overdirventool?
No I changed frequency using MSI Afterburner. But it needs to be installed on the PC. I checked Overdriventool, it looks perfect, but it seems it does not modify those frequencies in a card's bios directly. When I apply the max vram frequency to 700 MHz, it works ok, but in different PC the card has stock clocks again. So in order to have max frequency 700 MHz, either MSI Afterburner or this Overdriventool have to be used. I need the solution to modify those values directly in the card. Thanks a lot for any help!

hello,
since ETH is worth mining again:
how can i manage to switch my Vega Rig between CN Algos and ETH?
i use PPTable and OverdrivenTool to set GPU & Mem for Cn Algos..but if i want to switch to ETH i have to lower Core Clock to reduce power Consumption (and ETH didnt need that much MHz on GPU for good speed) - is there a way to switch on the fly without loading other PPTable and only load other OverdrivenTool.ini?

?? you don't need to load another ppt table. you can underclock the core to save on power on ETH. Both CN and ETH need as high the memory can go.
but i have PPT for CN with higher Core clocks than needed for ETH mining
so i have (or not?) to load other PPT with much lower p-states for ETH mining - i dont want to load other PPT and reboot every time i switch between ETH and CN algo
you can underclock using overdrive while still using a cn ppt.
figured it out with using phoenix first time...the voltages will override everything...but now i have to find stable mv again for each card
but i thought that i will save more power...cn8 with 12khs need 1000W on the wall...fast try with Phoenix miner give me 240Mhs with 900W on the wall

Hey guys
whats your intensity setting with stak2.5.+ in amd.txt for cn_heavy on 64/56?
im only getting ~1300h/s per card with intensity at 896
Im reading that people do nearly 1500h/s per card
on v8 i use 1984 intensity
and do you use something else for cn_fast/lite?
Thx in advance for any answers.

My 6xVega64 use stak2.5.1, algo Heavy,18.5.1driver Only get 7.8K,. But use stak2.4.7,20170823blockchain driver,can get 8.3k,Why?
the same parameters: core 1408/900 mem:1080/900 powerlimit -20%
I am running two Vega 56's on Windows and XMR-STAK 2.5.1 (v8) and averaged 4,500 H/s now running 4,100 H/s (with CPU)
the same parameters: core 1408/900 mem:1080/900 powerlimit -20%
Anyone having issues with the new version of XMR-STAK? Having hashrate issues. Old version I'm getting around 11,500 ... New version I'm getting 7500.
I am running two Vega 56's on Windows and XMR-STAK 2.5.1 (v8) and averaged 4,500 H/s now running 4,100 H/s (with CPU)
- Newer AMD drivers cause problems - I run Adrenaline 18.5.1
- It helped me to increase AMD config 'worksize' to 16 and 'intensity' to a higher number such as 1904
- When updating to XMR-STAK 2.5.x you need to start with fresh config files and tweak them after running miner the first time.

I stopped using power play tables since 18+ drivers. overdriventool is enough to achieve full hashrate at 165W with vega 64 and modified vega 56.
clock: set to 1600, voltage set to 850mV
mem: set to 1100, voltage set to 860mV
real clock is 1400 to 1500 depending of the card ; real voltage: 885 mV; shown in GPUZ.
4 cards rig is at 700W, system uses roughly 35W

This sounds like you still need PPT. Assuming a proper setup w/ PPT, actual voltage has historically *always* been lower than set voltage by at least 7-15mv, due to droop. A higher actual voltage vs what you set is exactly what you would have seen in the past w/o PPT, because your <=P5 voltages were fixed, and higher than your P6/7. Only thing is, those lower state defaults were usually much higher than 900-ish mv, so something strange is going on.
Also, a drop from 1.6 GHz to 1.4-1.5 indicates you are significantly off on your power vs frequency settings. Your card is being throttled because it doesn't have enough power, and sooner or later that will lead to instability. You definitely want to minimize that difference between actual and set frequency, by either increasing power, or reducing frequency. In the past, I've found that a proper ratio is around 1500 +/- 25 MHz for 900 +/- 15 mv
i notice something strange
when undervolting, at 900mv it use 115w in gpu-z for monero but if i add powerlimit -10 or -15 power goes up to 165w and the gpu clock drop a bit and hasrate also a bit, it also use more power at the wall
Sounds to me like you've pushed your card past some internal (or bios enforced) limit, so it's resetting to some kind of default.

that make no cense, why should it be lead to instability ?? powerlimit is made to limit lol, it s normal gpu clock get up and down, and for doing monero no need full speed but going below 1350 decrease the speed
Because throttling is a reactive behavior, and it is not instantaneous. There's always a chance that between the threshold exception and the throttling reaction that the hardware gets into a state from which it can't recover.
And not sure how powerlimit came into this discussion - we're talking about voltage settings.
