Hello! This post has been more than a year ago but I'd like to ask some questions.I grabbed the pics as stills from an HDR vid on my phone so the quality is godawful after messing with exposure etc. I've added some mildly psychopathic diagrams to help.
Link to video below too for better idea of where the inaccessible screws are on the card.
If I remember correctly, just the 4 screws around the GPU and four more for the backplate.

Just 8 screw holes
I guess you're encountering resistance from the thermal pads and GPU paste. Try twisting and lifting carefully.
The backplate can only be removed after removing the main cooler, so you can access the other screws.
I planning to deshroud my Pulse 7900 XTX and upon searching I saw that there are some screws that are not accessible. Were you able to remove the shroud without removing the heatsink first?

Ahem... Finally got round to it yesterday!
Decided to wait for the warranty to expire before doing the deed.
No instructions (booklet in box was for a CPU block), winged it, nailed it.
Hotspot max 42c - previously high 80s - running NMS at Ultra 3440x1440 at 100Hz, power slider maxed but everything else default. Steady at 100fps, barely drops below.
Yet to do any benchmarking, and I'll set no records as the Gigabyte card is only a two-plug PCIE supply, most others use three.
Very happy with that!

Very nice, I also have the Bykski block on my Sapphire MBA card. What edge temps are you getting?Ahem... Finally got round to it yesterday!

For anyone having trouble with multi-monitor power consumption: I upgraded to a 9000 series CPU recently, so I was able to move my second monitor from the 7900XTX to the HDMI output from the CPU. The 7900XTX is now able to reduce its memory clock correctly, dropping idle power consumption by something like 20W. It's now low enough that the fans on the GPU actually stop at idle like they should.
No quirks in the way it works either. It handles running games on either monitor, and even works fine with a game in a window spanning both monitors.
This is something I did in the past when it was possible to get motherboards with integrated graphics, then those went away, and now it's possible again due to all AMD CPUs having integrated GPUs.

Gave it a slightly stronger workout with BeamNG, got the hotspot up to 61c, gpu 49c, mem 51c.
The rig's in bits at the mo, for a long overdue clean, but I'll give it a good thrashing once she's up and running again and report back
I've had issues with this, I noticed the high draw while idle and went on an adventure trying to solve it and in the end I went back to just running my monitors off of the GPU due to the problems using split outputs worked. I too am on a 9000 series CPU now.
1) If you overlap SOME windows between each monitor, it bounces frames between the iGPU and the GPU and causes a very noticeable stutter in games, doesn't happen when using just the GPU as the output to all monitors.
2) If you have any video or hardware accelerated thing going on, on the monitor with the igpu you get stutters ingame, including things like background videos playing on spotify and adverts on webpages which really made the portrait monitor for web browsing pointless for me, even when it wasn't the focused window as the lag ingame was so jarring.
3) Specific to davinci resolve, you can't do dual window with any bit of stability, it'll crash and when it does work you get a very distinct "flickering" on playback, it's not there on the final video render but it's there on the playback and it's like a constant attempt at giving you a seizure.
The pro is that when all of these problems arent happening, is you don't use any extra resources on powering another display so you get everything for your game it's negligible but it's something to note, along with the lower idle wattage but you then have to consider the extra wattage your iGPU was pulling depending on what you were doing.
I run a main monitor (1440), a side portrait monitor (1080) and a capture card (1440p) which I mirror my main display from to another machine. Currently sitting at an idle (using chrome, discord, spotify, steam and other usual stuff ect) of around 100w. When I switched to the iGPU that wattage dropped to around 50w for "two outputs" which was my main monitor and the capture card with putting the side portrait monitor on the iGPU, the iGPU was then I think drawing an additional 10-25w, I actually can't remember but I remember it being something to consider. 1 monitor on my setup: 15w, 2 monitors 50-60w and 3 monitors is 95-115w from what I have written down in a chat with a friend.
If you're sensitive to FPS dips and stutters you'll notice it, it often felt like I was playing at below 60fps when my framerate was above 140, I tried with loads of combinations of freesync/vsync to combat it as I didn't realise at first what was causing it and thought my games were just broken.

Was going to say that hot spot temp sounds too good to be true. Never played NMS so I guess it's not very taxing at all. 60°C+ seems much more like it.Gave it a slightly stronger workout with BeamNG, got the hotspot up to 61c, gpu 49c, mem 51c.

What clocks is that at?

I'm RMAing my 7900XT Pulse over a faulty HDMI port.
Honestly a bit worried if I'm doing the right thing, who knows what the card I get back (if they replace rather than repair) will be like? Noisy fan? Coil whine? unstable if you touch the voltage, power limit or clocks? Unstable at stock? Any refurbished card that isn't in pristine condition?
Also, apparently, it could take up to 28 days to get a card back. Is it worth it?

@Gibbo
OcUK wont give you a used card in return
im sure in this case soon as they have another in stock, they would send you one (new)

I think they said they're going to test it to confirm it's broken and then they'll ship it back to Sapphire, who will decide what to do. I've no experience with Sapphire customer support so I don't know what they're likely to provide (I'm expecting a refurbished card).
If you just need a monitor for web browsing and desktop stuff. I’ve been using a USB C to hdmi adapter on a work laptop that can do 3840x1600. Dell do some docks that have multiple hdmi connections that can both do 4k

OcUK are giving me a B Grade card in return
B Grade could well be an item that someone received and then immediately shipped back.OcUK are giving me a B Grade card in return
I bought a B Grade monitor from OCUK once and it had under 3 hours of use time according to the monitor's log!

What makes me laugh is that there are no Sapphire 7900 XT Pulse card showing in the B Grade section (that I can see). So I'm wondering if it's something they just got in, recently, as part of an RMA...
Would be funny if they sent me my own card back as an B Grade RMA replacement for my card!

My hotspot takes quiet some time to get to 50c. I won't even take the cover off the top of my case half the time. But that's what happens when you have very other kill cooling.
Got a B-Grade 7900 XTX for a very decent price a few days ago. Have run Time Spy and a good 20 mins of Furmark without issue. Got it running LlamaCPP as well and it's been a great replacement for my broken 3090 there as well.
Very happy so far!
