My profiles atm are,
1800/995mv
1950/1100mv
2000/1165mv

thank you very much for the reply.

Nothing! Waiting for the 9900k and 2080ti to come out

So can someone please tell me what on "Average" these gpus need voltage wise @ 2000mhz, 1150mem ram? Want to lower voltage and maintain stablity @ 2ghz... help!!??
are you playing with vsync enabled?

actually, yes. I like the smoothness of it... should i not? I thought gaming with vsync on, would help make the gpu work less??

I can't get it stable over ~2000-2050 without the increased SOC from the + regedit file then it seemed more stable at those speeds with less v in some programs but others were doing funny things with clock speed dropping low and they would crash.
I need to do more testing but like you I am getting annoyed by the difficulty to find a stable OC over 2000 and the random nature of the crashes despite the increase to v.

I am thinking that it may need a higher v at low clocks for some reason maybe it isn't ramping up v fast enough with the change in clocks.


My Radeon VII seemed stable running multiple runs of 3dmark timespy, firestrike, extreme at 2125MHz core 1215mV 1275mem
This is with ~50% fan speed and the pump at ~3500RPM out of 4400RPM at which point it is nice and quiet but the down side to this waterblock is that the hot spot temperature is very sensitive to the pump speed which gets loud at higher speeds.
Some games would crash quickly at lower clocks with higher v so obviously 3dmark isn't very good for stability testing.

Edit:
Ok so the game it was crashing in had FPS caped at 62 and clocks would jump up and down from 25MHz to 2000+ which may have something to do with why this game was crashing vs other tests that did not.

Edit:2
Set 2dV to same as max 1215mV and now it actually seems stable at 2125\1270 but I don't really want to run the v that high at idle so hopefully there is some middle ground.

Edit:3
So far so good with the curve at 808MHz 825mV, 1466MHz 1120mV, 2124MHz 1218mV.
Hopefully I can dial it back a bit more yet.

Tested power use with and without the increased SOC from the profile and the difference was within margin of error, same goes for powertune over 20% it just didn't seem to be needed at this v.
Max power use at the wall was ~500W and max reported by GPU was ~300-350w

ok then that was the same problem i was having.
what you got to do is raise the minimum voltage slider in wattman until the crashes are gone.
vii tends to boost crazy where it thinks it has headroom I believe those crazy clock spikes and back down to 800mhz is what causes it

so are you saying bring voltage slider up from 808mhz @ (whatever stock is like .787mv) slide that up to like .900v and keep working the voltage slider up partially for all lower speeds? is this correct"?

just adjusted those voltages, and going to game for either a few minutes till it messes up, or this little tweak fixed it... ill be right back!

edit*** I raised the voltage to the following

808mhz - 902mv
1454mhz - 1080mv
2100mhz - 1219mv

Played about 20min of FC5 and all went ok so far... prior to raising those voltages, game would freeze in about 3-5mins. So this may have fixed my issue. want to thank you 2 guys who pointed this issue out to me... really appreciate it. Whats crazy tho is that i could benchmark this pc using heaven, msi kombuster, 3dmark time spy, etc... and never 1 issue, but playing a game with vsync enabled made all these issues appear, and i guess its cause the card drops speed and the lower MHz range it was falling in, just needed those bumps in voltage i guess. Thanks again, and ill report back if it acts up again.

EDIT number 2***

Just did about 45mins of heavy gaming and still ok, so thanks again guys!
