Meh, it's like a ti equivalent, pointless.

Temps will be poor with that tiny rad that's for sure!

Not a fan of that either, they might well be "reasonable" after all they cooled vega with a 120mm rad, though it seemed thicker than the one on this. 240mm would have been ideal but seems like they went 120 for more case compatability.

I'll stick with my 3*360mm and 120mm lol.

I've been reading about overclocking. And overclocks tend to top out at 2700Mhz. Which is pretty impressive.

I've been running for about two or three hours in games with clocks at just over 2600Mhz. Just to test the cards limits for now. So far so good.

I Will likely push it some more and then back off for everyday uaseage.

So far overall I'm really impressed with the card. Love the drivers and not any real driver issues on the latest drivers also.

Good to hear, you don’t really find any unhappy 6900 XT users.

Which card are you using?

robin66 · 14 Jun 2021 at 22:41

I have the Sapphire Nitro SE card.

No issues or crashing with DX 12 games anymore also.

You can get 3ghz if you have the XTXH chip

That's a crazy amount of speed. :eek:

@LtMatt Just binned off PBO attempting to push 200w into the 5950 on the MSI x570 gaming edge. Back to default and then VRM copes far better, added 4K onto my physics score so jumped from 51st to 41st this morning! New board has just been delivered too.

That's more like it. Your original score did look very low.

Oddly it got 30K in CB23 though (with 200w), but was tribble in 3Dmark physics. The Unify is nice and weighty, 1553g in its anti static bag. Its all those 90A power stages!

I really wish AMD would start shipping to the UK from the direct shop again, was hoping to find a ref 6800/6900XT to put a water block on. The Merc 319 6800XT i have is amazing but the water block is really hard to find

A word of caution about taking those overclocks at face values. Most people don't stress their GPUs enough. I can maintain stable clocks of over 2700Mhz in games for hours but TimeSpy GT2 on loop crashes after a while. I can run all 3d mark benches with around ~2650 MHz in-application clocks and pass all stress tests as well. I am not saying you are doing it wrong but just keep in mind that your clocks might not as stable as they appear.

Thank you for the advice. But like all of my GPUs, I test both on benchmarks and games. I find the max and then back off quite a bit for my day-to-day usage.

That's how you do it.

I take Abhishek's point though, some people run Unigine Heaven see 2700Mhz+ and think it's stable.

Timespy GT2 is literally a worst case scenario, it can draw tremendous wattage at one point during the test.

I also find Resident Evil Village with all the image quality settings turned up to be an excellent test of stability as it draws so much wattage that it easily sniffs out unstable overclocks with an uncapped frame rate and ray tracing.
