The RX Vega 64 Owners Thread

I'm now going for 1600MHZ Core in Wattman and 1000mv.
Results around ~1560MHZ core but seemed stable testing some stuff.

What should I leave running to fully test?

I like heaven its a good test for getting a game stable overclock.

Thanks a bunch my friend, so you just want me to 'very slightly' rotate/adjust the thinner of the two cables? Is this when your system is on?

Yes, best to do it with it plugged in so you can see if it works or not.

I found that one of my Vegas whined a bit during system restart at boot. Pulling that cable gently, or moving the zip tie around slightly solved it. Not sure why, but it worked.

There is no grantee that this will solve true loud coil whine, but for what i had it worked perfectly.

It wasn't whining right now, but I did both of the things you asked me to do, let's see if I don't get any of that 'quite irritating' whine for a couple of hours.

Thanks again

Loving the card atm, managed to get 1150 MHz stable on HBM2.

I have some observations I want to share with everyone, some of it probably will have been, but it's hard to go through 800 pages.

- It seems like I'm fighting a resource battle between CClk and MClk, I got the highest core freqs when I left memory at 945 MHz, the moment I bump Mem to 1100+ MHz, I seem to be losing about 10-25 MHz on the core.

- Trying to undervolt in very small steps to ensure stability, I managed a -10 mV Undervolt on p6/p7 at the same 1677/1750 MHz steps. Felt like it cut down 10 MHz or so from my core and saved me 20-30W of Power Consumption.

- Does the Memory Voltage Floor still do nothing? I am keeping it at 1000 mV atm.

- All the games I've tried at 1750 MHz p7 at 34x14 Ultra 40-70 Hz, I've managed to avg about in-game clocks of 1650-1700 MHz usually in intense loads. But in AC:Origins, it seems to be (not/or)using Vega to it's most efficient potential? I'm averaging about 1710 MHz + Core clocks with an insane 1150 MHz Memory (which appears to be 100% stable, played for hours). Attached a pic.

My main doubts will be, can I maintain my core whilst OC'ing the memory somehow?

Lastly, how do I go about Core overclocking on Vega LC's? I know it's not gonna make a big difference, but just want to find my die's full potential.

Merry Christmas everyone, came early definitely for me.

Yeah I was using heaven
Decided I'll just play mass effect as that maxes my card anyway lll

EKWB releases their new Fluid Gaming A240R kit and RX Vega water block

Got my sapphire 64 lc last week from you guys and loving it. Just gone back to order another and see they have all gone. Any idea when more stock and will the price be the same?

Cheers

No more of them now (unless they can find some), as they aren't producing the ref cards anymore, its custom only.

Yes i don't know why HWINFO64 causes that, i will pass details onto engineering so we can investigate. However, it may be something out of our hands and more app (HWINFO64) side as this does not happen when not using the app.

If you and @LoadsaMoney can provide your full system specs, OS/driver/hwinfo versions and the steps required to reproduce the issue, I'll pass it along.

i7 5930K, Asus x99-A mobo, Asus Xonar U7 USB soundcard, Sapphire Vega 64 LC on the 17.11.2 drivers, 16GB Corsair Vengeance LPX 2800Mhz Ram, 2x Crucial M550 1Tb SSDs, Win 7 Pr 64bit.

HWINFO64 v5.60, when going to the Sensor Tab, came up something about reading an Asus one (which im presuming is on the board), but just told it not to bother reading that one (selected skip or whatever it was, forget now

), then it black screened, and all LEDs on the card were off (only the cube and Radeon logo were lit), and the radiator fan span down, so tried a couple of hard restarts, but was still a no go, card wouldn't power up (the single power LED still wouldn't light up), had to do a hard shutdown (with the switch), to get it to come back to life.

Then i went and changed me duds

For all the criticisms of Vega that i see from some, there sure is a lot of happy Vega owners actually using the cards.

I agree. No one has said they are bad card, it’s just that there is / was better value for money Cards.

AMD aren't producing them anymore, all you can buy now, are the more expensive, and slower custom cards, like the Devil, Strix, XFX, and whatever else comes out.

soundb0y · 5 Dec 2017 at 17:18

Oh great. What's the point of that then?

I want a matching sapphire lc dammit!

There'd be even more happy customers if supply wasn't a complete joke.

Can get them elsewhere still, but i wouldn't pay what they want for em

Hey guys, so this is the best I've been able to get with my LC yet

Settings are - Stock frequencies with a 10mV undervolt on both P6/7. HBM is 1190 MHz (Tried 1200 MHz, it artifacted) , PL - 50%. Attached Superposition 4k Opt. scores. HBCC Enabled to 13GB. Quite happy about this personally considering my last LC which crashed within a minute on Turbo Mode.

Other data - 1170 MHz HBM was 7167 , my 6800k's running at 4.2 GHz.

Use the settings we used in the Unigine Superposition bench thread so we can compare scores. 4K optimized is not maximum settings.

Just ran a test at 3440x1440 and submitted to the that thread. Surprised not to see your name under that resolution Matt?
