Temps are ok ~70'c.

Also Wattman keeps only Voltages after boot.

1600 @3,9ghz and 16gb @ 2800mhz.

You might be throttling from temps but I also had the issue in one game and was told to use clockblocker to prevent it. Many people have reported the clocks/voltages not sticking in wattman - make sure you using the latest drivers otherwise try overclocknTool.

And you guys (seen others in this forum) are doing away with >900mv for both gpu and hbm while clocking higher.

Some people are approaching 1800mhz and others like me can barely hit 1650 so yes there does appear to be quite a bit of a lottery on these things. Makes me wonder if this is why AMD set the voltage so high because of the variance in how they clock.

I have the alphacool and I got it because I want to be able to upgrade my card down the line, but honestly I'm not impressed with the hotspot temp, nor the fact that it blocks the BIOS switch, the LED switches and the 4-pin fan header. Frankly if you have the money and are planning to keep the card for a while just get a regular full cover block

My previous result was 6075 with the same settings, but +1% core speed rather than +4%. Kind of unbelieveable how an extra couple core mhz can net over 400 points higher in score. There was slight artifacting in this run. Bullzoid mentioned that at high clock speeds (1800+ mhz) Vega will stop drawing polygons that its supposed to draw, increasing 3Dmark scores. I may be seeing that phenomenon at 1500+ core. I just ordered an EK-FC and my cooling system is bomb-diggity, so we'll see if core temps of 40C can push this thing harder.

As for you, have you tried setting the voltage to 800mv at stock clocks? Also, do you have Samsung or Hynix memory? Hynix may not make full contact with the heatsink.

Today i played around with some new tests and below some scores and settings if somebody is interested:

Sweet smile.gif , you have some nice temps smile.gif , besides clocks. Even hotspot temp is lower than some I have seen. Considering it's unmolded die, members shares seem to suggest that molded die has lower temps/ tighter delta. Seems you have good mount/TIM application/setup thumb.gif .

Yesterday I posted a SOCCLK powerplay mod, 2 members have tried it and gained HBM clock past 1100MHz. It seems SOCCLK determines ceiling for HBM clock gain, perhaps have a play chap wink.gif .

Thank you for share of info smile.gif . Surprised hotspot temp as you state, as you have molded die and GPU/HBM temps were so good. Look forward to reading if you see in an improvement with reapplication of TIM.

i'd like to know how much other vega owners get reported as hardware reserved memory for their vega in fall creators update taskmanager.

here is mine, it just upped to 132 MB after being at 68.3 MB for a week. Here the **** goes again...

Only amd knows, probably small fixes/optimizations

You're running the EK block i suppose ? Guess the alphacool won't be able to match that, no matter how often i'm gonna reseat that thing, just too little direct water contact to cool core, HBM and VRMs that effectively biggrin.gif
Here's some settings that work pretty well with my card: 1637/1100 1722/1160 and 1637/1100 1732/1184 with 1105/1050HBM for both. These for now seem to run everything i throw at 'em without getting unstable...

Yeah, i was a little stunned too...thought i did a pretty good job with the TIM, so the high delta really did surprise me a bit. Will keep you updated once that kryonaut is here and i can motivate myself to rip that thing out of the case one more time biggrin.gif
I'm really not all too concerned about that hotspot temp anyway, as long as it stays reasonable far away from the 105° limit smile.gif

Thanks mate! Yeah was surprised too..
The very first time I didn't spent the time and installed the block with just quickly the X-method. Normally I always carefully spread the tim out.

And yes, just saw your posts on the other thread. Amazing work!! Will definitely try it out tomorrow. Keep u updated...

thanks and yes the ek block but on its own loop with a cheap ek pump and a 280 rad with 2 1600 varder fans running at about 1300(I have no idea how to get them to ramp to the gpu heat so I through them on the cpu...so if the cpu heats up the vga fans ramp up...yeah dumb I know but hey smile.gif

now those settings are you using one of the LC bioses? last time I tried that it would over clock the thing to stupid speeds and explode like a *the rock* movie tongue.gif
and also what power limit setting do you use 0 50 25...
