I'm at 365 w using MPT but can't go higher as I'm hitting 100* junction temps (on air). Spent plenty of time adjusting GPU and case fans and can't seem to improve temps.I upped power just a bit on my 6800XT to get the 22k score. 298 watts @ max draw. It's an AMD reference black edition card, and while the fans are....not quiet....at those settings the temps are within reason. I don't keep my card pegged at that extreme OC, but I'll game all day with a pretty high OC on the card with zero issues.

hose of you hitting 21-23,XXX TS scores, are y'all running XTXH-spec cards or cranking up the power limit to 400ish watts (so presumably under water)? Or have driver updates helped since early in the year when we were all getting 20,XXX scores?
My 20.3k score from a few pages back seemed about mid pack at the time (Feb or so).

I have a huge undervolt, I actually didn't save my exact settings from my best run, but it was @ 1050mV or so. Playing with voltage is the where most dividends came from. My card can hit 2.8ghz but will thermal throtlle, but it'll run 2.5-2.6ghz no problem on a full benchmark without thermal throttle and that's where the big score numbers come in.
Edit: Ran a couple quick benches to show settings/temps, don't really have time to push it today but a good example. Note: Purchased a 12700K and moved to Win 11 since the previous benches so that's altering results some I'm sure with a new motherboard/OS.

My scores went down with 11.
So, I updated the drivers, reconfigured the case fans, then set the mem clock to 2,130 as thecold suggested. With the core clock at 2,600 (50ish MHz less than the runs in Feb) I ended up at 21.9k. Junction temps in the mid 80's, or about 5* cooler than before the fan reconfig.My 23,411 is with power limit at 430w and under water on an XTXH card.
I think it is very possible to get high scores with lower power and non XTXH chips if you are lucky and get a chip that doesn't mind being seriously under-volted, but that was not mine. It became unstable as soon as I tried to lower voltage below like 1150mv
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
You've got a good sample though. My gaming temps are fine. But hot spot in time spy will get to 110c easily, even 100% fan. But It's also pulling 350watts or more. Best score was 20,300. The thermal pad does a pretty good job, and once you break that there is no going back. So you're either stuck with trying to find another pad, or get lucky with paste. I need a second card for science...I took the reference backplate off, but from what I've seen repasting is not only a PITA but not huge improvements. My temps on the 6800XT BE haven't really been an issue, though, with some aggressive fan curves.

I'd say anything above 22k would be a decent target given that you're on water.What should I be aiming for on a Gigabyte waterforce 6900xt power and clocks wise?
Any if these AMD Reference 6900XT? Trying to get an idea of what to expect.

Tried looking for yours on here and didn't find it.My results are from a gigabyte version but it's basically the reference design with a gigabyte logo stuck on.
Just reran it. Last year I got just over 16k on the total score early on and I think around 18-19k on graphics after playing around with overclocks. Put a better cooler on my 5800x and overclocked my GPU to:Tried looking for yours on here and didn't find it.

That score looks on the low side ... what else could be at play here, CPU/RAM, VRAM ?2704mhz core
stock memory timing & speed
1134mv core voltage
+15% power limit
Increased fan speed
Yeah, not sure. Always scored lower even when i spent more time tweaking it. Tried raising the clock speed more but it's crashing. I didn't think to change the min value this time, it's still set at the default 500mhz but I think I remember increasing it before.That score looks on the low side ... what else could be at play here, CPU/RAM, VRAM ?
You got very high clock speed (2500+), but lower graphics score (19266) ?
Gideon's reference 6900XT and mine look to have very similar results:
Both score around 21250 (without OC or SMT changes) and have a GPU clock speed around 2250-2300 when looking at the 3DMark graph...
Interesting ... I played around a little bit more and in my case, the max slider doesn't seem to have much effect, but as soon as I put the min slider around 2500 (so at least 100 higher than my 6900 normally does), then the clock speed effectively raises, but at the same time, the FPS is lower and score drops by 2000-3000 points (lol, just got 17821Yeah, not sure.

Ah, that's a good improvement ! And thanks for confirming.Ok, just retried. I seem to remember someone saying setting the min core clock higher but not too high works. I set the min core clock to 1100mhz and kept everything else basically the same and got 21023 on graphics and 17,592 total.
When did you bench your card? AMD drivers do age like fine wine. My score jumped 2,000 pts since last Feb.About 21000-22500 is what you will get on the 6900xt reference overclocked. Beyond 21k is luck of the draw.
I'm pretty sure stock was close to 20000 for me.

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.When did you bench your card?

In the last several years, AMD never had a driver that is ready to use at the launch of the cards that they announced.time to put down the bong, dude. it doesnt matter if the card is red or green...measurable performance uplift over time at driver level is extremely common with new architectures, either in average fps or frame pacing. you botching the measurement of a 5% reduction in peak frametime value (or whatever) doesnt make that iterative architectural optimization a myth.
Nice start. You're probably hitting power limit at 293W. What I would do is just up your PL in MPT to like 350. keep all the other settings, see if your score goes up. It should your Power Limit is now higher, and your clocks will be higher.So went and tried my AMD 6900XT Reference with very little knowledge of Radeon GPUs(as I'm generally a Nvidia guy. VRAM: 2150, Min:2400/Max: 2800, Power: Max(15). Board was only pulling 293W. Next I'll learn to use MPT and see how much further I can take this card.
Coolant temp: 23C
