Congrats on ordering the new card - hope you have better luck this time! Didn't you order a new 850W PSU when you were having trouble with the LC card?

Thanks, I did order a psu but it went back with the AIO. This air models store page say's I'll need a 750 watt minimum so if I need to replace the 650, I'll grab a top end 850 or maybe the 1000 watt rmi, That way I can't go wrong.
Soldato
Ah. I think you'll get away with the 650W ok anyway.
Good luck with it, hope it works out better than your AIO version!! And I think you will be fine with the 650W. It would be very unlucky if you had two bad cards in a row

Fingers crossed, Cheers.

So tempted to get a Vega 64.
I'd really like a AIB Vega 64, but we've heard nothing so wondering how much longer we'll have to wait, maybe I should just go for a reference card and a good set of noise-cancelling headphones...

As the price drops I may spring for another one in the new year. Looking for one that'll hit higher clocks than this one which seems limited to P7 1769MHz for some reason. I've seen it boost up to 1800+ at times stable, so not sure quite what's going on here.
Soldato
my maximum clocks are so different from one driver to the next, it's very weird. On my previous driver I was hitting 1800mhz, this latest driver, it wont do 1800mhz on the same voltage, so need to push more voltage through it.

It's very odd as it's an application of the Core Clock that's causing the issue. I can have it undervolted to 900mv meaning it won't actually get over 1500MHz at all, yet set to 1800+ on P7 = failed SuperPosition run. Also getting pretty high hotspot temps now since I've switched to the Waterblock, which is very odd seeing as the water block should be able to cool far more efficiently than the standard block...
Going to repaste it and get some Conductonaut on there instead of Hydronaut when my CPU block arrives. See if that helps. Will probably put the old tension bracket back on too.

Wasn't there some Vega's with the HBM and CPU at different heights? If so was your's one of those?

Installed my 8GB Gigabyte Radeon RX Vega 64 Watercooling last night, no dramas, other than the card would "squeal" under high load but I think this was down to the 2 x 8 pin power connectors not being seated correctly.
Very noticeable upgrade from my Fury X (which is now on the MM for anybody that's interested), I've done no tinkering other than having a quick blast on DOOM and Wolfenstien: New Colossus (GFX Cards are for gaming after all).
In DOOM with my Fury X I was hovering around 45/55 FPS, with the Vega it's north of 120 FPS.
When I come to tinkering I will probably just undervolt and stick framrate cap at 75FPS for Freesync

Nope, moulded die here. I think it's a bit of a case of poor pasting by myself! When the CPU block arrives I'll re-paste it with conductonaut

Recommend enabling HBCC 11.8GB too for a extra FPS boost, along with +50% power limit.
Overclocking HBM generally gets you more FPS on core, so start there. Aim for somewhere between 1025-1100. If you experience a black screen hang and the GPU leds go off, you'll need to dial back a notch.

Thanks Matt for the tips, happy to remain in the Red Team and the jump to VEGA, I would have preferred a bit cheaper but that's mainly because I'm an old and bitter skinflint

Fair enough, If I end up needing to do a re-paste what one would you suggest using?

Well I've seen a lot of people on OCN using Kryonaut and I would assume if I had pasted mine correctly it would have been pretty good. Conductonaut is a bit of a PITA as you need to seal the resistors with clear nail polish or something like that to stop any excess Liquid Metal shorting things out. I haven't personally tested many different pastes on GPU's though.

Sigh if only i could get HBCC to even show up.
You need to do a clean install of the drivers. I had this happen when upgraded from 290 first drivers was missing HBCC. DDU fixed it
Thanks for trying but i'm just moaning for the sake of it at this point, I've done soo many clean installs of the drivers already, Even tried all the driver versions for the rx vega and **** doesn't show up. It's a lost cause.

I'm using Hydronaut, hated applying it, but all is sound IMO, probably went a bit OTT with application.
I do look at hotspot temp, but average can seem more relevant for "day to day" purpose IMO.
3D loads seem to hit hotspot hardest, bionic is greater than f@h.
I tried 8774 LC VBIOS for ~30min, I don't think my GPU liked the clocks as had issues. It also maybe that ASIC profiling on LC VBIOS differs to standard V64 VBIOS. If so, it could mean I was getting crashes due to that. I have not opted to retest LC VBIOS again, just concentrating on tweaking profile on factory VBIOS.
Have you noticed any difference for GPU voltage when you use same settings on factory VBIOS vs LC VBIOS and load GPU with same app?
I also lowered DPM6 and HBM from 1000mV to 975mV. I would have thought by doing that the "curve" that ACG/AVFS maybe using would change, but I get still same clocks/voltage for same GPU loads. How is you GPU for this aspect?
