Has anyone got 2600Mhz plus on the overclocks for the 6800 XT? If so, what settings did you apply in the radeon overclocking tool? Cant seem to get past 2550 on my Merc 319

What clock speed do you actually see in game?

I can reach around 2500Mhz in game with 2550Mhz set in GPU Tuning, but that's my limit.

My sample does not appear to be one of the better ones based on other reports, but even so +250Mhz on the core clock (over the rated boost speed) is not bad.

A bigger power limit would unlock more core frequency.

In the interests of keeping a lower fan speed, i settle on 2450Mhz @1.075v (peak voltage) for 24/7.

Wow, exact same as you. The performance increase wasn't that much, so reverted to defaults i.e rage mode BIOS and left everything else default on the MERC 319.

You didn't answer my previous question, i have more for you too.

What have you got your memory speed at?

I find in games it's important to get the frequency dialled in as if you go to high it hurts performance and detracts from the gains from core overclocking. I tested several games standing still in various areas to check at what point i lost performance.

My particular sample can bench and get higher scores at 2150Mhz with Fast Timing enabled. However, in games i lose performance so drop to +2112Mhz with Fast Timings on.

What is the default core clock speed as shown in GPU Tuning for your sample? Mine was 2364Mhz at default, appears to be on the low end of the scale.

2100Mhz with fast timings. Any faster and i lost performance rather than gain. Mine was at 2406Mhz via auto overclocking.

That's not default though, i mean before you change anything what is the core frequency.

I've had my 6800XT for a week waiting for the EKWB water block to arrive. All assembled now and in the case.

Just running through some benchmarks. Stock in Timespy is 13000 and 13500 in rage mode, that's with a stock 6700k. I'll do some overclocking later.

Incidentally the not entirely cheap EKWB waterblock came with an obvious manufacturing defect.

Pretty slack quality control.

Edit: still working out how to insert photos, I'll get there soon. I think that's it.

Settings for my new Graphics Card RX6800 Nitro+OC. Absolutely hands down the most amazing gpu i have ever owned. And the easiest to overclock. Unfortunately

Below is my current best 3Dmark Firestrike and Extreme scores. Pretty darn good tbh

I can't help but feel this card has a lot more to offer.The +10% power limit is definitely hamstringing the performance.

got a 6800 and impressed with the build quality, the thing is built like a tank

I got a 6800 as well but sent it back as faulty. I kept getting signal lost on the DP sockets and it refused to detect my Pimax 8K more often than not. It would also give motherboard VGA errors randomly on starup. So hoping OCUK find it faulty and replace, to be honest if they say no fault found I will simply DSR it as I know 100% it is faulty. I Tried 2X seperate PCs and it gave the same errors on both.

The strange thing is it is partly upgrade, partly sidegrade and partly downgrade compared to my RTX 2080.

RT and DLSS enabled games gave me a downgrade, for example with quality DLSS I get higher FPS on the 2080 with RT off in both Cyberpunk 2077 and Watchdogs 3. I know DLSS is not native and without DLSS I get about 40% better FPS in both games on the 6800. But DLSS 2.0 actually works well and enabling it has little IQ loss for a big performance increase. In this scenario the 2080 beats the 6900 by about 15%-20%.
In many older DX11 games it is a mild upgrade at best with maybe 10%-15% beter performance. But these are already pegging my 4K monitor at 60FPS with Freesync, so not a big problem.
Newer DX12 and Vulkan games I get about 40% better FPS.

So it basically varies from game to game. Though it is definately an awesome GPU and a quick undervolt and overclock had it running 2450-2500 MHz in Cyberpunk at 4K medium/high settings... well at least when I got it to boot successfully. Overall I would prefer to keep a working 6800 over my existing 2080 as more often than not the performance gap is there and is notiecable.

Yeah good score that nice clock too. I can only dream of such high clocks.

Alexrose1uk · 17 Dec 2020 at 20:49

That is an epic single card score; you have a Graphics score literally double mine, and I have a 2080 so not exactly anything slow!

It is a guy from Guru3d forum. And i think that is reference card, you can read his posts there in the owners topic. He also shares his settings.
