The RX Vega 64 Owners Thread

Very nice Tony. Undervolting is working wonders for my "stress testing". I'll be pulling the Ryzen machine apart tomorrow to install the Eisbaer so with luck will have some good results to post after that.

Edit:

One other interesting thing, using WHQL 17.9.3. On my 2 x 290x machine, CF enabled, I see 1 x control panel (AA, tessellation etc) and two Wattman panels, one for each card. On the 2 x V64 machine, I only see one of each, CF is enabled and working though.

It would be nice to be able to control each card's power/volts etc. independently as one may have worse RAM etc.

Anyone else seeing this or do those with 2 cards see two Wattman panels?

Additionally, the 2nd card (without a Wattman) is showing it's getting about 780mV when the other is getting the 950mV set in Wattman per GPU-z.

I suspect the CF/mGPU is still a bit immature. It looks like they may be trying to merge multiple cards to appear as one large one, which would be cool if it can be pulled off properly.

I had two Wattman panels when I had dual 290X and dual 390s.

Let us know how you get on with it, thinking about getting one myself

I went with the 120 due to space limitations but as mentioned will hook it into an Eisbaer 280 and probably a 2nd GPX or maybe just a NexXxos GPX (no pump) for the 2nd card as 3 pumps might be overkill and would add even more wiring.

@Bonjour That matches what I am seeing on my 290s alright, so now we need to hear from someone with 2 x Vegas (@AMDMatt?) for confirmation on what they are doing.

Like I was saying last night, 17.9.3 has been fantastic on Vega 64 for me. Clocks are stable at a higher speed, doesn't seem to be dropping as much as previous. Plus I'm able to set 1800mhz @ 1200mv now which was unheard of on previous drivers. Project Cars 2 is performing amazing as well, everything at ultra and 1440p with medium SuperSampling.

Wow, amazing clocks at such a low voltage!

Any word on 3rd party Vega 64s yet? (Obviously AMDMatt can't answer even if he knows)

I'd like a Liquid Cooled one, but not at the current prices, plus they don't seem to be getting the good chips (like the 3rd party ones)

Will do

I expecting good results with me buying the 240Rad

Dicehunter · 8 Oct 2017 at 17:42

Just curious but is the board power of 345w on the liquid cooled V64 available on the air cooled model as well just say if we swapped out the air cooler for a waterblock and maybe flicked the bios switch ?

Dempsey22 · 8 Oct 2017 at 18:49

Any reason why my 1700/1050 superposition scores are lower than my stock scores?

Thanks Matt. I'm so impressed on this latest driver, the clock speeds seem so much more around my target clock of 1800mhz. Amaxingly at times you can see it actually hit 1810mhz, I'm guessing because I'm using less voltage, it has more voltage headroom.

Just bloody loving this card, everything about it makes me smile. Gaming is great, freesync is great, temps of 40c on average is great, relive recording looks great. Its just been a real joy.

I'm quite happy with mine once I put an Air 64 card under water. I had to go with a 360 and 280 though to keep my delta t where I wanted it though since I use the Evolv ATX TG case and Vega generates a ridiculous amount of heat. My card isn't near the overclocker you have though. HBM is fine, but I can only get my core to about 1732 before it starts crashing in benchmarks. Which LC bios are you running?

This was with p7 at 1722/1200, HBM 1100:

TonyTurbo78 · 8 Oct 2017 at 20:44

@kundi I think from memory it's 8774 version, I can't get to my pc to check tonight though.

Thanks. 8774 caused some weird stuttering issue on my card. Maybe I'll give it another try though.

Edit: Nevermind. There seems to be two versions of 774 floating around. The MSI one works fine but the Powercolor one causes stuttering for me.

If you get good results put it on this thread and represent some, not enough red there. Needs to be Ultra/extreme
Is 6800k a suitable cpu for performance with Vega, Im not that keen to swap motherboards but considering my options

I actually didn't bother updating to the latest driver this time as I hadn't seen any improvements with the last 2 updated. Think I'll do that now and see what happens...

6800K is fine for Vega. I'm running a 3930K until my new PC is ready. Still waiting on RAM to arrive

The most recent 17.9.3 is supposed to be WHQL too, in theory that should just be a stamp of approval on the 17.9.3 beta, but maybe there were changes? It definitely seems more solid (other than Wattman).

I'm seeing 76MH/s on two cards with 520W total system draw which is pretty good (making them earn their keep when not gaming!). The 290x x 2 rig gets 52 for the same power.

Dempsey22 · 9 Oct 2017 at 11:39

Anyone help me out with overclocking ?

I'm running Vega 64 on water.

I tried last night but was getting higher scores at 1550mhz than 1700mhz+
