Dang, I need to try my Asrock Phantom again. I got about 21,200 with MPT, but that was a year ago, and before I got a water block on it.

Alright,

Well before anything. This is NOT a valid score, just getting that out of the way first. Reason being, I don't have the Futuremark Systeminfo update to sync clocks on my system for a VALID run. I'm going to be fixing that tomorrow with a fresh install of windows. This took about 4hrs of tweak using MPT. Gotta say, I'm SUPER impressed with the Reference cards(This being AMD ref). Never thought I would be able to get 24k out of the GPU. Anyways, I'm happy with the tinkering. Started out at 21.5k(Valid run). Now that I have things dialed in I'll get the Systeminfo sorted for a valid run and maybe push more. MPT is pretty amazing! 5950X @5.1ghz 2717mhz max GPU clocks, 409W board power

Hi, I got a reference 6900XT last October after 6 months of trying my luck in the weekly Thursday drop on AMD.com, I almost fell of my chair that I finally was able to get from the cue in the shop to place an order ... had to lay down for 5min to recover from that.

Happy I stumbled on this tread, had fun reading it and thought I'd also give it a try with the pointers read here:
But first try gave me 12411 graphics score ? On second try, luckily, I spotted the fps at a steady 75 ... yeah, ok, I had Radeon Chill still on :D
With that out of the way, here are some scores and findings with different settings (but with power limit always +15% and SAM enabled):
  • 20660 (1175mV, VRAM default)
  • 20780 (1175mV, VRAM fast timing @2100)
  • 20959 (1175mV, VRAM fast timing @2150)
  • 21100 (1160mV, VRAM fast timing @2150)
  • 21171 (1150mV, VRAM fast timing @2150)
  • 21239 (1140mV, VRAM fast timing @2150)
  • 21491 (1140mV, VRAM fast timing @2150, SMT off)
  • 21512 (1140mV, VRAM fast timing @2150, SMT on, RAM OC)
  • 21499 (1140mV, VRAM fast timing @2150, SMT off, RAM OC)
Power draw seemed to be max 293W, and max GPU clock seemed to hoover around 2360-2400, with temps around 70°C.
Tried 1130mV, but that would cause the second graphics test to fail.
SMT off (Ryzen 5900X) the first time gave me a boost off 250 points, but when overclocking RAM, there seemed to be no difference anymore in graphics score when turning on/off SMT ?

Original plan was to put an EK classic WB on it, but didn't get to it yet ... I just really like how the reference card looks :D, and it is also very quiet even under load, it hangs at the wall at arms length in an open air case and it never bothers me (... in comparison, my old Vega64 reference, that HAD to be put under water, because it sounded like a vacuum cleaner).
Don't turn off SMT for CPUs 12-core and below. Really only worth turning off for more than 12.

+24000, that's a nice number :D

Dang, I need to try my Asrock Phantom again. I got about 21,200 with MPT, but that was a year ago, and before I got a water block on it.

Catsonar2 got a similar score (+/- 21500) as me with a reference card without MPT, and you got 21200 with MPT (air-cooled), so I thought to also try my air-cooled reference with MPT. Just to play a little, not looking for the limits.

I only set power limit to 300W, didn't touch any other value in MPT.
Typical settings in Radeon tuning: 1140mv, 2140 vram, +15% power limit.
My max GPU clocks are just below 2500. Power usage nicely maximized at 345W, max hotspot temp 88°C if I remember correctly (fan curve 100% just to be safe-playing around :D)
Score was 22317 ...
Guess with staying nicely at 345W that I'm still power limited ... but without allowing the fans to go to 100%, I probably will get close to being temperature limited ?
Anyway, not really sustainable, but fun to test.

With a waterblock, it seems that you can add another 50W to the power limit, that's about 150W in total (from the default 255W to 409W).
Coolant temp: 23C
What water-cooling setup are you running ? (5950X @5.1ghz is also nice)

Ita a test bench setup and just stick it outside when it's cold enough. 5950X@ 5.1/4.775 1.41v, 560mm 44mm thick EK rads, 32GB CL14 Bdie tuned, Asus Crosshair Hero VIII, 1300W PSU

That's true (probably) only for the stock cards, if you overclock them you will get improvement from the driver if it fixes a problem with a game, which one is very, very rare and specific for a few games.
For me, this 'fine wine' is a myth. And this is very easy to be tested, I did it with my old RX 480, Vega 56 and my current 6700 XT.
You can get better FPS/scores if you repair/reinstall your Windows/VC++ libraries/broken video driver, but that's different.
I'm not entirely sure what you getting at. It's pretty common for AMD drivers to improve for quite some time after launch, and the gains occurred to my card at stock settings and OC'd. These gains could have occurred closer to launch than when I re-benched in Dec, but either way a 9-10% improvement at 1080p and 1440p ain't bad.

OK, I test it for you, and you can see a fast check.
Drivers:
22.1.2 and 21.4.1

Do you see now the "fine wine", 9-10% or... nothing?
There is no "improvement", but they just clock your card via the driver.

433W total power w/ 26C Max GPU 3800 CL12 RAM(highly tuned)
Still tweaking with MPT. Just need to tweak SOC voltage(current 1175mV) and I'll be able to make larger GPU improvements. I have been able to change SOC to 1200mV but didn't do a run.

Make a chart someone is willing to maintain with 6800/6900 3dmark results like the 3090 thread, I'd love to see what people are pulling on higher ghz insanity with the better binned silicon.
I agree, OP just simply needs to copy and paste from the Nvidia thread. Plus it would be great to show how much more powerful the 6000 series are compared to Ampere.

Has anyone tried repasting their reference 6800/6900? I'm thinking about it on my ref 6800 xt black to try and bring the junction temp down for OC runs. Normal gaming junction never gets above 72c which is really good. But trying to get a good Time Spy score is becoming an issue. haha
Yes, I repasted mine with KPx. I'm watercooled though so my temps will be drastically different.

here we can have some friendly competition for achieving the highest Time Spy GPU score. Overclock all you want. Time Spy is available for free here.


We are focused on graphics score, not overall! This allows anyone with a 6900XT and or Cracked out 6800XTs to be competitive since CPU does not play a major role in the GPU score.

The rules are:
1. In your post, please include the score and a link to your validated result, and tell us if it is air cooling, water cooling, or extreme (AC, chiller, dry ice, LN2, hard mods, shunt mods, etc).
2. Leaderboard will consist of top 10 scores per cooling type only.



Have fun!

Sure, why not.

My best score to date was in this post:
Just realized I forgot to update.

After a little bit more tweaking, this is the best I've been able to achieve.

I may be able to walk up the core clock by single digits, but I don't think I'll be able to do much better, at least not without extreme cooling.

Here is the info again:
Graphics Score: 23411
Overall Score: 21714

This is a 6900xt (XFX Speedster Zero WB) on a regular (but beefy) water loop.

So, how do we do this, do we update the leaderboard ourselves?

It would be awesome if OP R-Type would be willing to update and edit it in the first post in the thread.

On a side note, has anyone else had issues with instability after AMD driver updates?

With my old Pascal Titan X the best stable settings remained the same for years across countless driver revisions.

On this 6900xt, it seems like every single time I update the drivers, the settings I had are no longer stable, and I need to tinker again to make it stable.

Is this normal for AMD, or is there something wrong with mine?

I will update accordingly and keep an eye on it. I just got done going through all 10 pages lol. I have a lot more score that I wrote down. Just need to get links to peoples TimeSpy Runs and whether they are on Air or not to see if I need to switch people around on the list. I wish I could give everyone the ability to update my post. Don't know if its possible.

What drivers are you using? I'm still on the old 21.7.1 drivers from last year. Not sure if 3DMark has update their database to accept 21.10

I did not realize that 3DMark had to update anything to recognize drivers. I usually upgrade drivers every few releases when there is some sort of benefit. I recently installed 22.2.1 to add Dying Light 2 support. Before that I hadn't updated for a few revisions since I didn't plan on playing any of the games in the release notes.

I mean, when it comes to drivers I'm kind of used to just installing whatever the very latest is, and only not doing so when I'm being lazy. I've never intentionally held back for any purpose.

Yea, they are always a bit slow on that unlike Nvidia's latest drivers are verified, no issue.

Oddly I can't get MPT to work on my system. When I try to select my card it just shows a blank option unless it's a fresh reboot, but even when I can select the card it seems to do nothing when I update the max power.

Have you dumped and loaded the firmware from your GPU using GPU-Z?

I'm using the same one and used 1.37.1. 1.38 seems to be the best that works for my reference. One thing I'm noticing if you have issues with MPT is that you have to test different versions of MPT to see which one works best for your particular card.

I think this is the last time I ran it: http://www.3dmark.com/spy/24118057
I'm running a full cover water block with MPT set to 325W, which lets the card scale to ~360W with the power slider maxed. Good for about 22.5K in graphics score, despite running at x8 3.0 in this X470 board...

Post 1 updated, took the chance to insert my score as well. :)

Well finally managed to break 20k on timespy, did some card tweaking to see what I could get up to. I am going to need a cpu upgrade to go much further though, as that is what is holding my score back

https://www.3dmark.com/spy/26262182
What do you feel you need a new CPU? Your 3900X has about another 2000 pts capability. I see you are running 3600mhz on RAM. What is the CL? Is it a single or dual rank kit?

I dont really need one, but I do like to upgrade and want to get the last big upgrade for my AM4 board. As for my ram its a 64 GB CL 16 dual rank 4X16 kit.

What do you do with your PC? Game? Anything else especially having 64gb of ram? CL16 is fine. Here is my 3900X. This is with Bdie CL14 3733. If you do a 5900X will be great but even a 5800X is also a great option.
