Having run benches for Hitman 3, Red Dead Redemption 2, Horizon Zero Dawn and Far Cry 6 I can confirm that there is no noticeable difference beyond margin of error from running memory at 2000 vs 2150 so running VRAM at higher speeds seems pointless.

I also compared undervolting (960Mv / 2125Mhz) vs running at stock (1150Mv / 2449Mhz), Hitman 3 ran marginally better undervolted, Horizon Zero Dawn ran the same, Red Dead Redemption 2 and Far Cry 6 both ran marginally better at stock speeds. I may try to see if I can up my GPU clock speed whilst remaining game stable at ~960Mv.
 
The primary reason to undervolt IMO is to reduce power draw and heat output, and therefore lower fan speeds and reduce noise. I get ~5% more performance in benchmarks, which is minor, but it also uses around 18% less power, which is huge.
 
Just bumping this topic to see if anyone can give (or point me to) a down a dirty guide to trying a few undervolts? I've had my 6800XT for a few months now and loving it, but want to consider an undervolt to reduce power draw.

(I also need to get a second PCIe power cable down from the loft as I'm running a single cable with a "dual head" or whatever it is. I've read recently this is bad on a card that can be drawing up to 300W).

Consider just reducing the power limit only. I done this on my 6950 XT and sacrificed only a 3% drop in performance for lower temps and fan speeds… I didn’t like how the default settings ran for me.

Have any of you with the Nitro+ re-applied your thermal paste at any point? I was just wondering if it was an easy task. It's been a while and I want to try and refresh it and get some lower temps. I'd normally just whup it off and re-apply but I thought I'd ask if anyone had done it first ;) Any tips or info I should know etc.
 
I finally got a Red Dragon card, is there a way of benchmarking to check everything is as it should be?

Rather what would you recommend for testing my system out, perhaps with some comparable results?

Sorry, it's been a while so I'm not up to date with these programs any more.

I'll be using PTM-7950 on mine (MBA).

My 6800 XT (midnight black) just arrived from the states, pretty mint and has not been taken apart. I plan on changing the TIM and wondered if anyone has used PTM-7950 on their GPU?

I Dunno the vendor, but replacing the tim if it's a new card is kind of a waste of time and effort. They run pretty hot anyway, so I wouldn't bother unless it's running temps outside of spec.

Did you manage to repaste your card? I didn't bother with mine. After doing a few tests at the time I posted everything ran /runs ok so I've left it alone for fear of making things worse :D
 
Has anyone still hung onto their 6800XT? I'm still using mine. Bought it on launch day for £680 I think it was. Absolutely can't justify spending £1,000 four years later for a semi reasonable upgrade as someone who isn't that interested in RT and plays games at 60 to 100fps (99% single player games). Still got plenty of VRAM. It's been reliable and the driver were and still are fine.

The only thing that would push me for an upgrade is maybe performance in VR
