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!

huh? hows ur "stock wattage" at 700W? curve editor doesnt help if 600 is the wall im hitting no matter the voltage or clocks that im running. if youre talking about miniscule spikes then sure, those would manifest in a few extra points in short burst benches, where that is naturally important. but over longer load periods that doesnt help much and just equalizes into basically nothing. but thats what im testing for, the longer loads. i was initially hoping that that extra leeway in powerspikes would help out in the overall average, but looks like thats not the case. ok back to stock vbios now, recording another baseline. then i can get an overview on everything and decide which vbios ill go with for D2D. in any case, one thing is for sure: we absolutely need higher power limits, thats our main brick wall here.

welp stock boost doesnt help me much if my max oc stays the same due to max attainable voltage and silicon lottery / stability 😄 sure leaving things at stock u might notice smth but not when all is maxed out. im mainly interested in having more leeway in terms of power limits, more flexiblity for spikes above 600W, since the 5090 is hopelessly power starved. but no luck thus far, they all behave the same pretty much. and yes ofc, im actually not surprised that the LC vbios versions behave so differently, not complaining about that 😄 just mentioned it cuz thats what stood out 🙂

damn so overall trust in sales is destroyed there huh?

hm dont like what i saw with the xtreme waterforce vbios. while the significantly lower rpm might free up a bit of wattage for the core and vram, temps shot up by 10C, in turn lowering clocks and voltages across the board. thats not really helpful... currently testing the PNY Epic-X vbios, all three fans functional and maxing out at 3150-3400 rpm, pretty nice. thats two fans at 3150 and one at 3400. iirc the epic-x sports two larger and one central smaller fan, so that makes sense. preliminary conclusions thus far: barely any difference between the vbios versions when it comes to avg. and max. wattages and resulting performance. basically all inside error / ambient temp. fluctuations. the only ones that stand out are the ones where the fans cannot be fully controlled, i.e. 2 out of three functional (Astral LC/OC) or very low max rpm (Xtreme Waterforce). after the PNY comes the Zotac Amp Extreme, then back to the stock Surpim to rerun the baseline with the updated drivers (576.28). so far not really sure what peeps are raving about with regards to Gigabyte vbios versions. granted, coming from a base model card, flashing the Master or Suprim vbios would give you a nice bump in stock performance due to a higher shifted V/F curve. but when overclocking to the same max. frequency and running into the power limit, differences are basically non-existent. btw can confirm that max. and avg. core voltages are unaffected by vbios, only dependant on type of load, temperature and available power budget.

done with the two gigabyte master vbioses, now on the Xtreme Waterforce. first thing i noticed: HWInfo only shows 1 fan vs. standard 3 but all three fans can be controlled as one and are spinning. however, max. rpm is only 1800 vs. 3000 at stock. lets see how that pans out under load. it "should" be fine since so far on automatic fan curve ive only seen up to 1600-1750 rpm max. under max. load. most interesting aspect will be power usage ofc. on to further testing!

sure thing, lemme grab two of the pics i initially took to illustrate, pretty straight forward actually: with the card installed in standard horizontal orientation, the power socket is on the underside of the PCB. at stock, there is a thermal pad placed on the pcb backside directly on top of the connector, with the pad connecting to the metal backplate (red circles). ive removed the pad and used two 30g TG putty pro batches to fill out the gaps over the core, vRAM and the power connector, all tracing a coherent line and connecting them (blue circles). then i just slapped Phobya Ultra 3mm thermal pad sheets onto the rest of the PCB backside where there was still enough space (indigo circles). sorry for the amateurish illustration, just a quick n dirty thing to provide some visuals 😄 noice, ill keep an eye out for that one then! finished Astral OC, same issue as with the LC namely that only 2 fans can be controlled. although in this case the max. speed is faster than stock for both at around 3200-3400 rpm. also just finished the Gigabyte Master, first success here with full control for all three fans 🙂 now off to the Master ICE. haha yep i recently had to chuckle when i realized that my desk was filled with Thermal Grizzly stuff 😄 its not that im a fanboy, i always compare a product type from all vendors, but TG usually ends up at the top of the wishlist due to a combo of pricing, performance and availability. Roman sure knows his stuff! and while he might be financially well-off, i dont envy him. hes basically a workaholic, working 7 days a week and has taken maybe 1 vacation in the past 5 years or so. hes also had a near miss with burnout couple of years ago, one of the reasons he dialed back a bit and left Caseking.

are u using a fan on the connector? ive also added putty on the connector backside and the cable is exposed to the 140mm fan im using to cool the RAM, so those two factor surely helped with the 4090 and will help with the 5090 now 🙂 btw, were back in business! just reflashed and Astral OC vbios and successfully installed drivers. Plan is to test the following: Asus Astral LC (already tested, gonna skip now due to limited fan support on Suprim) Asus Astral OC Gigabyte Master GIgabyte Master ICE (likely no diff to Master, but why not) Gigabyte Xtreme Waterforce PNY Epic-X OC Zotac Amp Extreme Infinity all the other vbios files currently available on TPU arent worth the hassle imo since theyre from reference boards / basic models. i didnt include any MSI vbios since i figured that the Suprim will likely have the best anyways across the MSI stack. will post results once done 🙂

speaking of vRAM temps: adding TG putty pro to the pcb beneath the backplate over the core and vRAM spots and filling out the rest of the PCB with large sheets of Phobya Ultra 3mm pads i got a reduction of 4C on the vRAM and about 1C on the core. not too shabby 🙂 im including checks for max fan rpms on the Suprim while testing different vBios versions. stock max is 3000 rpm and i must say: even at 100% the noise is not annoying at all, im impressed.

OMG! this is so stupid! LOL 😄 so i flashed back to the stock performance vBios, rebooted and tried to install the driver: again no dice! like....wtf? then i remembered something: sometimes nvidia drivers are behaving funky if theyre located too deep down from the root folder, basically if the path is too long they error out. so i copied the driver folder to C : and bam.....driver installs 😄 aight, back to the starting point then! at least this would be an easy workaround 😛

yep ive seen similar user reports with regards to driver problems after cross flashing. but not this wide spread....i just saw that for specific vbios versions. welp, glad im not using any of the standard included adapters 😄 F that

hmmm something funky is going on here. aside from the Astral LC vBios is cant install a gpu driver for any of the vbios versions ive tried. the flashing goes down without a hitch, GPU-Z always shows the correct vendor and vbios version. testsigning is also forced on permanently but nope, installer always stops with an error. will try a restore point now, maybe thatll shake something loose while keeping a vbios. edit: nope, no luck whatsoever. @johnksss got any pointers?

Astral OC vBios is OUT, cant even install the GPU driver here 😄 at this pace ill be done in no time LOL next up: Gigabyte Master

its fine, im happy with the new cpu 🙂 besides, the RAM binning will do some good for sure. cant switch up boards, too dependent on the big fat I/O capabilities. even the X870E Extreme doesnt provide as much candy as this baby. plus it aint available anymore on the market sooo.... no other option for me out there currently. aight, found a nice spot in AW2 that maxes out the power budget right to the 600W limit for the stock vBios and recorder a 1h baseline. now crossflashed to the Astral LC vBios, bro @Papusan might be interested in those results 😛 the crossflashing is a bit of a hassle this time around: crossflash - reboot - blackscreen - switch to iGPU - blackscreen but mouse cursor visible - blind password input - desktop visible but without icons - switch to dGPU - normal desktop - reinstall GPU driver - reboot. dunno bout u guys but crossflashing on the 4090 was way easier and faster. but welp, at least it works 🙂 edit: aaaaand the Astral LC vBios is OUT right from the get go 😄 only two out of my three fans can be controlled, the third just stands still. the second is boostet by around 250rpm in the max and the third slows down by -600 rpm. off to the Astral OC then!

ultimate gaming PC you say....? 🤔 specs sound somehow familiar 😏 soooo the tuned 7400 RAM profile from my previous CPU also works on this once. havent tested if i can tighten up the timings some more tho, jury still out on that. however, i must say the CPU side of things are quite positive. did another baseline run with 1h CB2024 and the new CPU beats the old one in every way! Temps: -4C cooler in Delta T Fan Speed: -20%(!!!) in rpm for AIO fans / -5% in rpm for case fans (this is at +2C ambient temp vs. old CPU baseline!) Clocks: +65 Mhz on average across all cores VCore: -16 mV on avg. Performance: +1.5% in CB points aight boiz, time to switch to the GPU side of things. need another Alan Wake 2 baseline for the thermal pad mod i did beneath the backplate, then its off to testing various different vBios versions 🙂 btw, my 4090 buyer in Italy just received the card today and did his initial testing: hes a happy camper!

what im most worried about is the "value freeze" that MLID has been speculating about recently: basically, just like with the SLI capabilities, Nvidia would go up the stack each year and freeze performance/buck in place vs. the previos gen. in the 40 series they did it with the 60 skus, now with the 50 series the 70 sku provides almost no value increase over last gen. if this gets out of hand and they start stalling the 90 series, were over and done with boiz. imagine intel skylake era 5% bumps with every gen 💩 with only enough reserves to make a bigger bump once AMD comes too close for comfort with their cards....

just wait for it, as of yet he still got it his hands on it 😉

uh oooh is the honeymoon phase over? are cooler heads prevailing? cmon bud, cant leave the 5090 club! 😛 edit: preliminary results on the new 9950X3D - welp, so far every limit of the previous CPU is the same, max. frequency at 7400 Mhz, max. FCLK at 2200, currently checking if my previous profile with tuned timings and voltages is also still valid. if thats the case, ill give it another go with 1:1 max settings, havent tested that yet. but yeah, definitely time to go binning for RAM kits, if switching out the CPU doesnt change anything... mobo is out of the question tho, hanging onto it!

nothin yet on the nvdia app. but no time for that anyways, gotta check the new cpu IMC first then its off to the races testing different vbios versions 🙂

i see youre a man of my taste when it comes to cars: cheap, functional, thats it. no frills haha
