ok. But there is no spreadsheet where a lot of people have put in values for what they could achieve?

Not that I've seen. Just have to experiment a bit. Generally I've been able to run a +180 or more below 900mv. That number starts to fall off some on my card at higher voltages. Others have had better success. Really depends on your sample and how low your temps are.

hi

i have a question i want ot replace my thermalpads from my backplate of my gainward 3090 phantom gs (96°C in gaming) what pads must i use? 0,5 or 1mm?

i found this here EC360® Gold 14,5W/mK (50 x 50 x 0,5 mm) is this enough for all ram chips on the backplate?

and i will also add on the backplate a aluminium heatsink 150x100x27mm

and what thermalpad shoud i use between the heatsink and the backplate? 0,5mm or 1mm?

Use Gelid Extreme pads. EC360 are highway robbery prices.
No I don't know what thickness.

question for you guys that are using a 5900x with a 3090 how much perf boost do you think there is over a 3900x@4.4ghz im Thinking maybe looking to pickup a 5900x but not sure if its enough of a boost to be worth it some of the scores i get with my 3900x right now.

I scored 15 643 in Port Royal

Have anyone tested Gelid Solutions GP-Ultimate 15w/mK vs Thermalright 12.8w/mK? Is there any difference?

I have Ultimate on the way but am returning them for Extreme.

Someone told me Ultimate are hard and flaky, and the Extreme are soft and compressible which is preferable for a thermal pad for GPUs.

Fixed my mem temps, since I switched from 1mm to .5mm some pads were not making contact.

Quick lap on the block core, still not perfect + removed some height from the standoffs. These seem to be brass, with 220grit + weight of the block, only takes about 5,6 left right movements to remove .1mm.

I don't have my temp/flow installed but usually my water temp is about 1c-2c higher than sensor thermal tape on the xr7 rad. So guessing about 7c-8c delta at 420w-440w.

Used tons of thermal paste to close the gap, some memory ICs were not touching the pads while others got compressed.

Didn't re-apply core paste lol.

Need to find that thermal putty that was posted here a while ago.

Maybe now that EVGA has revised the FTW3 it's equivalent. Certainly wasn't on initial release. I don't have either card but pretty obvious from reading various forums.

Does the Strix have fuses that can blow like the FTW3? Thinking about if you really wanted to push the card with the KP XOC.

OTOH, hard to beat EVGA's customer service.

How do i find out if I have a ftw3 ultra revised version?

On what card?

On my 3090 FE, Gelid Extreme pads (on the backplate, 2mm, 12 w/mk), oddly enough gave the lowest VRAM Temps! Gelid Ultimate 2mm pads were 2C hotter, and Thermalright Odyssey 2mm pads were 2-4C hotter than that! Unfortunately the Gelid Extreme pads on the backplate start turning into sticky putty (does not affect performance) due to the massive heat load, which doesn't happen on the front side of the card. No idea why the Extremes (12 w/k) are better than the Ultimate (15 w/mk) on the backplate but I assume it has to do with how they conform to shape easier while the harder pads don't contact perfectly (and cause slight warping).

On the front (core) side, Neither Gelid Ultimate 1.5mm nor Thermalright Odyssey 1.5mm are great due to the hardness of the pads affecting core to heatsink PSI pressure contact integrity (1mm is too thin), so Gelid Extremes for that are the best choice. (You can actually get perfect temps by applying the Extremes, screwing down the X bracket and backplate screws, then immediately unscrew it, remove the PCB, apply thermal paste and then screw it down again, an annoying OCD Protip).

odyssey pads are ok, you can actually stretch them before applying. I stretched them to .8mm from 1mm. Then they conpressed to .6mm easy.

I have a few spares now, but still left the iceberg pads + noctua paste. These are .5mm on the front.

The backpkate I still have odyssey 1mm and they are a mess(about 20+ remounts) but temps are good so I don't want to loose the 54c mem temps with new pads.

finally took the plunge and tried the 1000w bios on my 3090wb, one thing is when i do the nvflash ---protecton it failed , is it important or i can leave it just that?

It reverts back to protected automatically from what I remember from the last time this came up a few pages ago.

On the revised version it's marked "rev 1.0" just beside the PCI-E slot. Old one says "rev 0.1".

Luckly I got the new one then:

Wood Font Wood stain Varnish Vehicle registration plate


So this new revision card is on par to the strix right?
A couple of questions:
-Are you finding this chip (if good one) capable to 24/7 at 2000 / 0.950v or less?
-As I've read that ram tjunction temps (mostly upside chips) in some cases gets dangerously high, which temp would you consider the limit? I touch the backplate and gets really hot...

Thank you.

My Zotac does about 2010 900mv in TE GT2 / PR loops. I never tried pushing for 1,2bins more or less voltage in games.
I may not have the best OC card at high core voltage, but It holds 2115 easily at 1018mv and +1500mem with xoc vbios on any load.

Nice. 0.9v is great, did not had time to test under 0.95v, but definetly will do. +1500 mems leads to what final speed?

This is good info ! I'm getting closer to mounting both the Phanteks block on the 3090 Strix OC, and the Bykski block on the 6900 XT (both custom PCB, 3x8 pin) as part of my complete work+play machines home office overhaul.

For the 3090 / Phanteks, I probably stick with the supplied grey pads that look like they have some squishy adaptability (in spite of having plenty of Thermalright Odyssey pads in 0.5, 1.0 and 2.0 mm sizes available).

Interestingly, the Byksi block is build such that it uses only paste on the front side (GPU die, VRAM). For that, I plan to use either Gelid GC-Extreme or Noctua NH2 paste as those are a bit 'thicker' and less runny than the Kryonaut I usually use, not least as both GPUs are mounted vertically.
