ok kool once ure done testing just send it over to me 😛

duuuude! talk about a comeback with a BANG! holy crap how much did u pay for it?! 😄 we want: bench scores, power consumption, overclocking abilities (if any?), temps, driver support (as abysmal as for the 5090?), any quirks, potential watercooling and/or shunting planned? we want ALL the deetz!

"inflation" 😛 /s uuuh id like for you to keep us updated on that. both the CUDIMM and 2 vs. 4 dimm board performance on AM5 interest me a lot 🙂

first thought was of bro @Mr. Fox getting one of those. imagine him skipping the 5090 but getting a 6000 pro instead 😄 dude, talk about getting raised with a rolex spoon 🤣 i am partial to peasant Fossil watches myself, really like their design language 😄 soooo....shunt mod coupled with @Prema Mod then? 😄 btw, i decided to do another vbios comparison, this time with shorter burst loads via benchmark tools. ill focus on the Suprim stock, PNY Epic-X and Gigabyte Master vbioses.

Nnnnnnnnnnnnnnnnnnoooooooooooooooooooooooooooooooo dont sell it! 😞 dont leave the NH55 gang! but if you MUST: good luck with the sale bud 😄

correction on my previous statement: no increased OC, silicon limit remains the same even with the new vBios. card is behaving a bit differently, i.e. stabilities / instabilities at different points / in different benches or games than before on stock vBios. but overall stability point is still the same at 3240-3247 Mhz.

spot on, the differences are miniscule. ofc when doing benches those differences should be larger. and yup, the second one was it. i figured if a vbios allowed for a bit moar powah / higher voltage i could also squeeze a bit more out of it, so best to compare oranges to oranges and set all vbios testing to the same clocks at idle 33-34C temps. naturally, one might argue that slight differences in the overall V/F curve shapes might account for slightly higher / lower clocks depending on the vBios. but since im basically only interested in the highest V/F points on the curve, the range "should" be minimized. granted, if one would be interested in undervolting and going further down the curve, those variabilities would likely be larger. but not interested in UV 😄 all in all, 5090 beggars cant be choosers 😛 being stuck with the 600W wall means well have to find other ways to squeeze a bit more outta these chips haha

Aight boiz, heres the jist of my vBios testing. Testing conditions: Alan Wake 2 Chapter "Summoning" Savegame 4K maxed out with all RT / PT maxed +HDR. Driver: 576.28 (XtremeG Mod) Duration: 60 min. Flashing / Setup Procedure: 1) Flash vBios via NVFlash 5.867.0 2) Uninstall Drivers via DDU 3) First Reboot 4) Blackscreen upon Boot, switch to iGPU 5) Only mouse cursor visible, blindly type in password to login 6) Desktop appears, but no icons - switch to dGPU, all good 7) Install Drivers, adjust settings 8 ) Second Reboot for Nvidia Overlay functionality 9) Set 100% fan speed via MSI Afterburner, check HWInfo for readout 10) Check V/F curve offset vs. stock Suprim vBios, adjust core offset to reach 3240 Mhz at 33-34C (D2D OC profile for my card at stock vBios) 11) Run AW2 as detailed above, record via HWInfo in background. After 60 min. minimize game while still letting it run and do quick screengrab of dGPU section in HWInfo. I attached the screengrabs to this post, together with the PNY Epic-X vBios ive ended up choosing, for anyone interested. How did I choose which vBios to pick on TPU? Welp since most creation dates of the uploaded vbios files are the same, i just went by the most recently uploaded for highest chance to get the latest version for each card. Manually checking if its indeed the performance profile for cards that sport two vBios versions. Quick conclusions: - Asus Astral LC/OC and Gigabyte Xtreme Waterforce were disqualified pretty quickly due to lack of proper fan control (Asus) and very low max rpm (Gigabyte), respectively - Stock Suprim SOC and Zotac Amp Extreme vBioses demonstrated the overall lowest average and peak wattage numbers, resulting in lower core clocks. So they dropped out of the race, as well - Gigabyte Master and Master ICE vBios versions are basically identical, only difference here being the impact of differing ambient temps (+2C on the ICE), thus some impact on the clocks. - In the end it was a neck-and-neck race between the Gigabyte Master and PNY Epic-X vBios. I ended up choosing PNY due to the following: 1) Highest avg. and peak wattage numbers 2) Highest core clocks for avg. and effective 3) Highest max. RPM for the fans (+200 above stock and the other fan functional vBioses) 4) Highest average voltage, even when accounting for differing ambient temps. There u go guys, enjoy! Any questions or comments, lettem rip 🙂 edit: as an afterthought, some additional things i could have included: higher measurement resolution in HWInfo to better get a grip on wattage peaks / shorter, burst-style loads in terms of standard benches & benchmark scores. but hey, only got so much time to go around i guess 😄 MSI RTX 5090 Suprim SOC vBios Testing.zip PNY Epic-X OC 10-Apr-2025 (275445).rom

well id say were spot on then 😄 ive dialed in new OC settings due to the changed V/F curve, seems like i can now do +20Mhz on the core offset, pretty nice. although not sure if this is vbios / driver / backplate cooling related or maybe a combination of all three. not 100% sure yet on the stability for D2D but should be pretty close. gonna do a session of Deliver Us Mars later to finish it up.

here you go: This is with the PNY Epic-X vBios flashed with stock clocks, no voltage added. At stock and 32C, the V/F curve for the PNY is 45 Mhz higher than that of the Suprim. This is just regular OS install that im running day to day, so no extensive tuning. Win11 24H2 Build 3476 RTX 5090 Suprim SOC (PNY Epic-X vBios stock).3dmark-result

now thats a pretty nifty tool 🙂

sure thing, can post later once im free from work.

aaaaah now that makes sense 😄 yeah some were speculating where the stock wattage should be to let the card properly stretch its legs and guesstimates were exactly in that 700-750W range. i have so much thermal headroom, even on air! those couple houndred extra watts would be no problem whatsoever... well well, 5090 still in your possession, shocking 😉

i know he was already testing a "KP-ish" card at PNY, but is he actually still with them? i thought he said hed be moving back home this year stateside to be with his family, so working for a taiwan-based manufacturer wouldnt be in the cards anymore / having sufficient opportunities in the US. still, could be that PNY took some of the KP input and implemented it into their vBios 🤔

aaand done! well i guess im going with the PNY Epic-X vBios from here on out, who knew 😄 in the end it was a neck-n-neck with the Gigabyte Master vBios. the PNY provides higher avg. voltage, higher max. rpm and also higher avg./max. wattages. all that results in the highest avg. / effective avg. core clocks. thx to @johnksss for bringing that card to my attention, otherwise i wouldnt have thought of looking at it 🙂 ill provide more details tomorrow, now its bedtime!
