I have just got 2 Vega 64 cards............when will Crossfire be supported?
Ok, just got a response from AMD.
"Thank you for the email.
I understand you are not having Crossfire option in Radeon settings with 2 Radeon RX Vega 64 cards.
Our driver team is currently working on it and this will be in future driver releases. As of now Crossfire option is not available for Vega cards. I do not have any information on ETA. Please subscribe to the below link to get notified about upcoming technology announcements:
Thanks for contacting AMD"
I think it would be best to wait to see if Crossfire is enabled on RX Vega by the AMD Drivers Team.If they do not enable it, for what ever reason, we should not even try to.
Note my comments about the potential power draw of a Pair of Crossfire RX Vega 64 LE based on the AdoredTV Data running PREY on a single Vega 64 LE card.
Also note that a 1500W power supply is actually advised for a system with Pair of RX Vega 64 LE. There is a link in this thread somewhere about that.
I had started a thread in this Community forum about that but I have almost lost interest now. I will reply to or update this post with a link to my thread about Prey sometime later, you should be able to find it though.
I have some data running a single and a pair of R9 Nanos on Prey and the power draw from those is reasonably high on my i7-4790K System running the Prey Demo on Windows 8.1 64 bit OS. I deliberately took that data very early on in the Prey demo in an attempt to make it easy for others to get the data.
I was interested to see if someone could cross check the AdoredTV claims running Vega 64 LE on Windows 10 64bit OS, and also if they could compare what Power Draw they see versus what I see using the Demo version of Prey using Windows 10 64bit OS.
Unfortunately AdoredTV test case requires purchase of Prey. Jim from AdoredTV ran his test case just after the entrance to the Hardware Labs in PREY, which is just after the door where the Prey Demo ends ... just my luck!
I contacted AdoredTV about it on asking if he had any numbers from earlier in the game but he had to drop work on RX Vega LE and move on to testing threadripper.
I do not want to Purchase the game just to do this test so unless someone could loan me access to Pray over steam for a couple of days (Family Sharing might work?). I cannot test my system at the same point that Jim from AdoredTV did.
Maybe you or someone on this thread could look into running that Prey Demo / Compare what you see in Prey Hardware labs with me if you are interested?
No Windows 8.1 64 bit OS Drivers for RX Vega /Vega FE means I will not be buying Vega cards, but I might as well hand the thread over to someone elso on the forum.
If AMD Drivers manage to reduce the Power Draw in Prey at the same point tested by AdoredTV, or people cannot manage to replicate his results, that information needs to me sent out to help AMD and people who are happy to purchase and run RX Vega 64 LE on Windows 10 64bit code at the very least.
Anyhow I got to go.
Hi Did you mean special drivers downloaded from Guru3D.com? There have been many different small groups of people working on various 3D technology for GPU. Lots of their work seems to end up on Guru3D.com in some way or another. I think it best left to wait until AMD Drivers Team enable Crossfire.
Good luck with your build.
Maybe you can post the build to the Forum.
Are you sticking with Windows as your main OS or have you thought of trying Linux as Primary OS with Windows on Virtual Machine using PCIe Passthrough to access hardware like GPU and PCIe based SSD?
It should be a good solution to allow you to move away from Windows as your Main OS, Run games directly on Linux where possible, but have a high performance Windows on Virtual Machine which should be able to directly access your GPU and get good gaming performance.
It is just a thought. It is what I want to attempt for my next build.
Just thought you would like to know the good news that the AMD Crimson ReLive 17.9.2 Drivers have been released and they have support for MultiGPU Vega (2 cards).
Here are the Release Notes: Radeon-Software-Crimson-ReLive-Edition-17.9.2-Release-Notes
Driver is available on Windows 10 and Windows 7.
GOOD NEWS PEOPLE!!!
WE HAVE CROSSFIRE!!!
I take it you tested it and it works ;-).
Yep, works. I was hoping for a better score........but at least it works.
Might see some improvements with driver development.
I've been running a few benchmarks in crossfire with XFX RX Vega 64 air cooled. I have a similar score to your 3dmark score except I am using an old i7 4770k 4.5ghz. Here is my score http://www.3dmark.com/spy/2422421 I've run Rise of the Tomb Raider and Hitman 2016 benchmarks and crossfire is working. I also played a bit of the Witcher 3 and it ran good in crossfire. I was worried my 1000w Thermaltake psu would be enough but everything I've run works well.
Timespy is a DX12 test which tests MultiGPU (DX12) ... and is not the same as Crossfire (DX11).
I am a bit confused that the driver notes just say MultiGPU not Crossfire. I am not sure if AMD are just using MultiGPU to mean both or not. The interface to MultiGPU(DX12) is confusing. Sometimes you need to turn Crossfire On in some games and benchmarks to enable it. Sometimes you have to turn Crossfire Off in AMD Crimson ReLive Global Settings and enable it in the game or benchmark.
How much "scaling" improvement do you see running TimeSpy (DX12) when running two Vegas versus running one? Are you seeing 1.8x or 1.5x or 1.2x?
So have you tested if Crossfire (DX11) is enabled?
To do that, (and of most help to me), would be if you could run 3D Mark Firestrike (not Ultra) with Crossfire On in Global Settings, and also please make sure you have the Crossfire Logo set to On to ensure it is really running in the benchmark.
I have some TimeSpy MultiGPU (DX12) on i7-4790K with Dual R9 Nano somewhere if you want some comparison. In fact I can update to the exact same driver as you if you want and rerun my tests just to check MultiGPU(DX12) is running.
It might be interesting to see how Crossfire Scaling is looking between our systems at the moment? Although you have managed to get MultiGPU(DX12) running, you sound disappointed with the score. If it is not scaling well in TimeSpy (DX12) or if Crossfire (DX11) isn't running well then that should be looked into I guess.
I have another comaprison point for you if you wish.
I have already run a number of tests using the Final Fantasy 14 Stormblood benchmark.
I was meaning to post them before I decided that no Windows 8.1 64bit & general state of the drivers & Performance/Power = No RX Vega/FE for me.
Here is the link to download the benchmark.
FINAL FANTASY XIV: Stormblood Official Benchmark
It is very easy to run.
I will write up my results. Post them in a thread and you can compare what you see to my results if you want?
I ran the benchmarks on Windows 10 64 bit on i7-4790K with a pair of R9 Nanos on resolutions running from 1080p up to 4K using Virtual Super Resolution mode.
I was seeing excellent performance improvement and scaling in Crossfire.
I have a number of Vega comparison results kindy posted by other RX Vega owners.
A pair of R9 Nanos was definitley beating the single RX Vega numbers I have seen.
It would be interesting to see how RX Vega/FE scales in Crossfire and Power Consumption in comparison to the R9 Nano's I have here.
It might be the case that the scaling is worse on the Vegas because the total power draw has been limited for example?
Sorry, I've had a busy day of work.......just getting time now to do some testing.
I've attached 4 images of 4 benchmarks with and without Crossfire enabled in Time Spy and Firestrike. (for some reason I am unable to upload Pictures into the thread)
I enabled the Logo and it was displayed in Firestrike but not in TimeSpy, so I'm gathering that's a DX12 thing.
Yes, definitely post up your results......am very interested to see how the Vega's stack up against last generation top of line GPU's.
I am a little disappointed, but I still think it's early days yet.......and the cards are blow style which means they are susceptible to throttling due to heat.
The Vega's top out at 85 degrees, and I know they are certainly hitting that limit. Water cooling will certainly be on the cards (no pun intended) :-)
I hope this helps you. Cheers.
You have some seriously low scores on single GPU, whats up with that?
Are you sure that you are not hitting any PSU powerlimits or you have dialed down the clocks or smtn?
My Vega 56 on vega 64 bios does 24,5K on GPU atleast on Firestrike and 7,3K on timespy. Still on air, will receive waterblocks soon, then it is on...:)
Off course the fans are loud while I bench but....:)
Your scores aside, the scaling is bad....for now. Still I am somewhat happy AMD addressed the issue sooner than later.
But atleast both our cards will see some work from now on. Will post my benches once I get some time.
Thanks for the pics by the way:)
Best of luck with optimization:)
You guys are happy now?
Happy that they finally supplied what was advertised.......yup :-)
I agree, it is low........and I think it is do with the 2nd GPU in there.
When benching the first GPU it seems to heat up quite fast.....and could be throttling.
Would don't mind telling me your Wattman settings?
Would like to try them. Thanks.
Thanks, I will do this.
I gotta catch some z's now.....early start tomorrow, then i'm away for 3 days for work. :-(
Would rather stay home and play with the Vega X-Fire!!
Nice....I just reset everything back to default in Wattman and ran benches again and got a 1000 bump in the Graphics Score in TimeSpy, so I'm guess my Overclocking skills are just rubbish.
AMD Radeon RX Vega 64 video card benchmark result - AMD Ryzen Threadripper 1950X,Micro-Star International Co., Ltd X399 …
I also have a 1000watt Corsair HX1000i......I ran the benches in Turbo mode in Wattman, and the Corsair 4link software reported the PSU hit 994watt!! Lol.
I think you will be safe with a 4770k though, as the TR has a fairly high TDP.
peimad i will be slipstreaming my win 7 disc tomorrow.. can you pls check these things. greatly appreciate the help:
1. is FRTC working with crossfire
2. is wattman working correctly with crossfire
3. p1-p5 power states unlocked?
4. whats the peak power draw in crossfire?
1. Sorry, haven't had a chance to test this one.
2. Wattman is working well with Crossfire
3. Nope, still locked.
4. With the Threadripper peak draw with Wattman Turbo setting was 994watt in Crossfire.
Using Win 10 64bit.
Hope this helps.
Sent from my iPad
ok, some info from my experience:
1.FRTC is working fine. like it is supposed to.
2. When looking at user silentgame scores on timespy, i`d say it is working okei. Will test my xfire tomorrow.
3.with 17.9.1 drivers the p1-p5 states were not visible on WattMan, but now i can see the clocks, but still locked.
4.My power draw with XFX 56 (64liquid cooled Sapphire bios) power draw is around 325W, measured from the wall.
Here are my scores and specs:
AMD Radeon RX Vega 64 video card benchmark result - Intel Core i7-4790K,ASUSTeK COMPUTER INC. MAXIMUS VII HERO https://www.3dmark.com/3dm/22291488
silentgame : 4770K is still ok, your GPU clocks are quite low also, so there`s much headroom. Provided you have the cooling.
Also, higher RAM speeds help out, as I read from various forums. Is normally not true, but with the AMD`s CPU-s and GPU-s (this generation) it is equally true. So they say...
What else you should all have done by now with reference coolers:
NB! Take off those heat collectors (backplates)
Have a fan blow on the back of it if possible. it helps.
And I hope you plan to upgrade to waterblocks....otherwise you are holding your hardware back...and those fan noises - bad for your hearing:D
Mine arrive in couple of weeks.
Something else I noticed....if you bench, make sure you don`t have WattMan open - felt like it was more stable. My experience.
the last run i had my manual P6/P7 states were 1672/1687 with voltages accordingly 1.2v/1.215v core.
sry....can`t add any pictures for some reason...
GL HF (with benching):)
Yeah I had a problem overclocking my RX Vega in the previous driver, in that it just wouldn't overclock (crash, freeze) so I haven't tried it yet with these new ones. I was able to overclock on the first driver they released just for Vega but every driver since it just won't run without issues. I just played some Rise of the Tomb Raider and ran around in the soviet installation and the remnant camp for a bit and it maxed out my gpu's memory and core usage, and also my cpu was being used 80-100% on all 8 threads so I am pretty confident that 1000w is enough.
Here is the data I promised:
MultiGPU (Crossfire DX11) Benchmark - Final Fantasy XIV Stormblood Benchmark. RX Vega/FE Results please?
Here are my crossfire scores like I promised:
1x GPU Vega 56 (64bios) : Timespy
AMD Radeon RX Vega 64 video card benchmark result - Intel Core i7-4790K,ASUSTeK COMPUTER INC. MAXIMUS VII HERO
2x GPU Vega 56 (64bios) : Timespy
In Firestrike 1xGPU I had 24,6 gpu score, now with 2x vega 56 (64bios): Firestrike
Looking from the numbers, one would say that it scales almost perfectly, like 95% in my case. That is great, it can only improve from here.
My powerdraw from wall was GPUs only: 700W in Firestrike and 665W in Timespy. I don`t mind the draw, with undervolting etc. I can bring it down easily, but for benching I dont mind.
F.Y.I : MY PSU is a LEPA G1600W. So i have plenty of headroom.:)
Also, I repasted the cards as soon as I got them, that also helped with temps. When waterblocks arrive, that will matter less....
Best of luck to you all,
Just getting an login prompt (eventhough I already am logged in), So I log in but am greeted with an "Unauthorized This place or content does not exist or access to it is restricted. If you think this is a mistake, please contact your administrator or the person who directed you here."
Could you post the results somewhere else?
I quickly got hit with the hard truth that my Cooler Master V1000 PSU is not enough for my dual Vega 64's like I thought initially . I had no problem stability testing them by mining on them for 24H together with the CPU, when I tested about 3 weeks ago. Which basically is the same as putting them throught furmark powerwise from what I saw, a ~800-900W powerdraw)
Even if I run them on the powersave settings now (or downclock them manually to 1200 Core/945 mem @ 1.000V), I am having stability issues in games. Eventhough my powermeter reads only around 400-600W from the wall for the whole system, games are unstable/crashing (I am on custom watercooling). And if I try some more demanding games the systems shuts off completely. Really disappointing as my PSU is atleast goldrated and got great reviews when I first bought it a couple of years back.
Looking at an EVGA Superonove P2 1600W right now, as I want to be safe and will be upgrading to Threadripper sometime in the near future, and overclocking it.
