I've played a bit with the tuning percentages, pushed frequency up 5%, voltage down to 93%, Vram up a tiny bit, and power limit down 5%.

No real idea what I'm doing, but it's still stable and in theory a little faster and less greedy.

I might try that as a conservative starting point!

Stupid question but I assume overclocking doesn't affect warranty these days? Haven't bought a new GPU in 6 years and I think it was so-so then. Brand specific.

Same here, however I did try forcing the PIC-E slot to gen 3, I don't know if you read my post on this earlier in this thread though but just to clarify, my system wont power on at all with the card plugged in, the psu just clicks and there is no power delivery at all (tripping I guess), so I actually used my old card to get into the UEFI and and set that (even though I did not see that as being the issue in this case, I can't see anything physically wrong with the card but most of it I can't see of course as it's obscured by the cooler). I have 2 systems and neither will power on at all with the 6700XT plugged in, just for 'giggles' I even switched the older cards over between those two systems and they are fine, it is just the 6700XT that will not work.

Those systems if you are interested are;

i7 10700
Asrock Z490 Steel Legend
750w Antec HCG 'Gold' psu (only about 6 months old)
Old GPU is an MSI GTX 1080Ti

Ryzen 5 3600
MSI B450M Mortar Max
EVGA Supernova 650w (I think this is a gold efficieny model too, can't remember now as this is about 4 years old)
Old GPU is an EVGA GTX 970

If there was any doubt at all about power supplies I think these two should have it covered ...and if it will power a GTX 1080Ti it will power a 6700XT, which uses a chunk less power.

Oh you got an rma already? I thought I needed to wait till Monday ie their website says hours m-f.

Ya my system won't power on either, tried it again, think it's 5x now I tried it. It's warm so I know it's drawing power when plugged in. Ya I tried it with 2 diff systems 850w corsair gold and a antec 550 (ya I know but wanted to check). Neither booted (no screen).

I'm not sure I want another one of these... If they are made poorly.

Mine arrived, installed without issues and is quiet and seems to be performing well. It doesn't seem to be achieving the boost clocks though. It seems to max out at around 2430. I might try some tweaking but even as is its a far better card than I expected.

What did you upgrade from?

sgoaty · 27 Mar 2021 at 20:28

It's going to replace my 5700xt but at the moment it's replaced a 2080ti just for testing so not really an upgrade. Also it's only boosting to around 2360 not 2430 as previously mentioned.

Shaolin Chicken · 27 Mar 2021 at 20:30

Ah ok, hopefully you can get it boosting properly.

It's even easier on AMD. See the first few seconds of this video on how to do it.

Thanks. Easy enough but taking off 5% voltage gave me errors in 3dMark and driver time out errors....needs tweaking I think.

Unseul · 27 Mar 2021 at 22:17

I'm currently mining on mine (no I'm not a "miner", I bought it without even knowing if it was any good, or if AMD had integrated drivers to stop mining etc). But if I'm browsing, and whilst there's a bubble, why not. This is pushing it to 100%, but I guess a game/benchmark could stress it in other ways, but it's showing 2610mhz clock speed for me now, and vram at 2028mhz. Voltage is around 1140mV. Using 176W. (All this is according to the radeon software.

That voltage and GPU clock is unnecessary you can lower the power used , mining only needs memory clock

So you downclock the GPU clock and lower voltage and try increasing memory clock and increase the fan speed and monitor temps , especially memory temps all can be down via AMD software

I would suggest Google / YouTube what the 6700xt can do in mining this will give idea what voltage and clocks to work with

From what little I've read, that could eek out another 5% or so? Which I really don't care about, a few extra pennies makes little difference. But that extra 5% performance in VR, or just in games in general, is more helpful, which is where I really want it. I guess I could setup different profiles, but... meh

. If I get bored I'll check it out i guess

.

EDIT - The voltage is already reduced (at least that's what I read it as on the radeon app.

I have said this before - its false. Some algorithms do like core clocks!!! Some tokens are dominated by AMD some nvidia. The whole purpose in tweaking is to find the best hashrate combination then the try reduce power so your consuming less electric for almost the same hash. Just because right now the lucrative player is on ETH which is a heavy memory algo does not equate to all mining needs is memory clocks!

Bingo.

When i'm not gaming, i've found a sweet spot for my 6700XT on ETH is around 2.3Ghz, 2038Mhz on the Ram and it will happily do that at less than 900mV meaning a GPU power draw of around 127W - the 50W difference in heat output is noticable compared to stock and you still get around 40-45MH/s

You can certainly push it much lower and reduce the power draw down by another 20W but then you are losing around 25% hashrate.

With such a big cooler on the Red Devil and a fan speed around 1600Rpm it sits in the mid to high 40s temp wise.

The fighter might be a bit warmer but nothing some more airflow wont solve.

Are you using the Radeon software? I've noticed that even if I've set it to 1030mV the reading at the top still shows something like 1140mV and the power draw readout still maxs out to whatever the %has been set at.

NutritioN · 28 Mar 2021 at 10:23

Are you using a 'gaming profile' or changing the Global tuning? I found changing the tune for a profile while the program was loaded, had no effect. Had to close and reopen the program.

Unseul · 28 Mar 2021 at 10:41

Global tuning, changes have effect with no need to restart.

Quick question. When dropping the mV too low, I get a driver timeout error. I presume this is due to me playing with the mv, rather than just a software issue that happens to occur at the same time?

Mine is set at the following in Radeon Software

Max Frequency - 2353 MHz
Voltage - 1005 mV
Vram Target - 2050MHz
Power Limit - Minus 2%

That gives me an actual clock of 2310MHz @ 887mV and the VRAM speed of 2038GHz all for 128W when Running an average of 44.5MH/s over the last day.

Custom fan profile has the junction temp at 48°C and a Current Temp of 44°C fan speed of around 1600 - 1800 RPM

Not the most efficient card to do that though so its only when it's not being used - my 6800 for example draws maybe 1W or 2W less and returns around 60 MH/s

Tried to put those settings. Moment i pushed apply, there was a driver timeout error.

Nowgetting the driver timeout error on settings that seemed to work ok before as well.

I had to slightly increase voltage (1%/) to 94% and my driver timeout issues went away. I suppose keeping the undervolt and reducing clockspeed slightly would work too which is what I'm going to try later.
