Hey guys how does this look for 7900XT ? :) I really want to break the 30K ... Maybe its doable
Temps seem hot. Take the side panel off the computer and crank the fans up to 100%. Do XT have the same memory chips as XTX if so you can go higher on the frequency for the memory. 2800MHz, try it anyway as it will do no harm.
 
I will be honest, too: I replaced the original Bykski pads and their bad 3 or 6 W/mk with soft 15 W/mk Fehonda pads, purchased in the Krisfix shop, linked in my posting above. Bykski's pad thickness is 1,2mm, Fehonda's 1,25mm. Also, I left out the spacer rings that come with the water block. These actions are providing the card with excellent temperatures. But maybe they also killed the VRAM's OC abilities.
That’s good practice to replace the crappy padsand I don’t think 0,05mm would make such of a difference alone.
Maybe if the 1,2 was already too thick and new pads hard.
I prefer to first assemble the block without any paste or pads, to see how’s the die contact (is there light shining between) and then gauge the actual gap for the memory pads.

One more very important thing with these cards having four VRAM chips right next to eachother - you basicly have to use individual pads sized max the 12x14mm of the memory chip itself.
If you use single piece of pad, say 15x55mm for example, there is no space for the pad to ”flow” at the middle and it will not compress, but will bend/deform the PCB instead and risk the BGA joints instead.

By removing the spacer rings, do you mean the standoffs?

Only with the Preview Drivers I was able to reach 30400k graphic score in Time Spy... The WHQL driver scores much much less :(
Maybe i should try get 31K with preview driver then........ Or are scores with it marked as "not valid" ?

Ur average clocks are higher then mine but scored a little bit lower, maybe try a different driver?

The new pads are less hard than the originals.

Thank you for your thoughts. There is a pad flow in the gap between the chips indeed. But honestly I don't see a problem in that. Here are two pictures from the predecessor card, same modell (please ignore the two small pad pieces missing on the block). Looks like fine contact to me. Please note: this one has shown no VRAM issues after installing the block.

I don't think the pads are responsible for the current Mem OC problems. I agree that something bent the PCB and made the BGAs lose contact, probably myself while disassembling the air cooler. This will hopefully be fixed by reflowing as reported before.

I mean the spacer rings that come with the block and which Bykski recommends (orange) to place between the cooler and the PCB.

I followed this instruction in one of the several assemblies I did while trying to solve the VRAM issue on the current card. The temperatures with the rings installed were awful, about 90 °C hot spot temperature. They are just fine without them, almost too good to be true actually:

Take a look at a few driver comparisons I did yesterday if you like. Tell me what you think about the GPU, Mem and Hotspot temps with several 500W+ stock Time Spy runs. HWiNFO columns from left to right: current, minimum, maximum. Translations (bottom of the screenshots): Wasser = water; Luft = case temp; Raum = ambient temp. Water flow was about 135 l/h.
 
Compared to the 23.11.1 driver, I was able to increase my 3DMark scores a little bit with the latest preview driver :
  • Time Spy graphic score : +639 points (from 36590 to 37229)
  • Time Spy Extreme graphic score : +162 points (from 18055 to 18217)
  • Port Royal : +30 points (from 19911 to 19941)

But I did not manage to make AFMF work in all the tested titles : Cyberpunk 2077, Hogwarts Legacy, The Ascent, Alan Wake 2, Robocop.

I disabled Vsync and Freesync, enabled fullscreen in games and checked the fps with AMD overlay. What do I do wrong ?

I got AFMF back working when I manually put the game into the amd driver game profiles and started it from there.

mate i did just that with my xtx did one pad for 4 memory chips and yes i put tp-3 1.5mm instead of 1mm for EK waterblock and yet my mem temps are one of the lowest i saw here in this forum.

so now should i be concerned for the memory pads or not, do i cut them now individually or not ?

2 speed way test only difference was the room temp 5c less on the green graph
hot summer 27-28 rom temp memory is at 66c max
and yes i can overclock the memory to 2750 and the results are the same

those temps are just fine have similar ones with small test runs
 
Guys What is a decent pump-res combo if I want to throw a block on the 7900xtx?I was looking on Mod my mods and performance pcs earlier and there was quite a variety saw a few sub $100 should I be looking at those?

I would avoid the ones that have the outlet/inlet ports made out of plexi as they crack very easily, also look for one that has a d5 pump.

The D5 should be able to cool both cpu and GPU right?

hello!!!! Above I included pic of oc settings and pc setup. I have 7900 xtx red devil, 11900k cpu and case is nzxt h9 flow. I was having constant pump out issues with the red devil so went with thermal grizzly cyrosheet been running it for about 2 months so far and just nervous wreck with temps and just want to get confirmation im good haha. Soo I've been doing 4k gaming 100% gpu utilization max temps so far after 4+ hours is 58c gpu/78c junction at max 70% fan speed. Are these good temps? Am I ok if it gets hotter from a more demanding game? Would you guys recommend any changes in settings or anything? And finally delta usually around 20c sometimes Jumps to 22c this seem to be ok and what high temps should I be ok with? Sorry for all the questions this has been my first ever custom pc build so prob babying it like crazy haha I want to thank all in advance for the help!

Tbh thats an amazing overclock if stable! even harder to believe if your actually stable allday long at 1050mv, havent really seen any xtx go below 1090 for allday stability. cs2, mw2, etc i can play at 1090 as the lowest posible, for stability, even 1080mv i get crash, timespy i can run all way down to 1020-1025mv, but no where near thats stable for allday gaming etc.

i would test this in all games possible, if its really stable i really had a sucker card in comparision, heck even most in this thread proberbly had..

Hey! Thanks so much for the reply and so far I've gamed for 4-5 hour sessions at these settings and haven't had any issues only play a couple games those so haven't tested alot. But my Temps ok? Good-average-high? And what would be safe for me to get to and not worry?
