pretty cool, couldve gone 50 other ways straight to gpu melting hell instead 😄

so guys, for easier follow-ups here the author profile on overclock.net as well as his newly set up GitHub page for the magical mVolt tool that lets us unleash our GPUs via software ONLY 🙂 overclock.net profile: https://www.overclock.net/members/b00nza.701858/?filter_threads=1&filter_replies=1#activity GitHub: https://github.com/b00nz/mVolt/ latest version now supports profiles, profile set at logon, V/F curve editor and other UI tweaks. i did a quick check last night, both Xbar and GPU Core Voltage adjustments work flawlessly on the fly, same with Clock offsets for Xbar, Core, vRAM. like....no need for anything else anymore, really 😄

HOLY CRAP! here i was, just about to start work in the office when i stumbled upon this, bam 45 min gone LOL. omg cant wait to check this out once i get home.... what a total middle finger to Nvidia, friggin hilarious! show them those melons, guys! 😄

you win some, you lose some: GPU cable keeping steady, still at +/-10% max. current imbalance, roughly equating to 1-1.3A, very happy with that. but now suddenly my machine kept crashing during RE9 Requiem gameplay, sudden black screen followed by a reboot, not BSOD, no warning, no freezing, nothing, just instant reboot. had a hunch so i ran TM5 and voila: the RAM started getting unstable! currently retuning the timings while keeping the speed at 7600. not sure if this is silicon degradation or rather the current heatwave. ambient temps are reaching 28-30C in my little gaming corner in the living room, thus pushing the RAM to the upper 50s during gameplay (remember: this is with RGB switched off and a 140mm fan pointing directly towards them). in any case, back to RAM tuning ugh....altho not much in the mood, crazily enjoying my gaming phase 😄 ill just do it on the side, one timing a day i guess.... 😛 at least i found the culprit quickly and can go back to stable gaming without reboots 🙂

unfortunately i cant use native cables, still rocking 2x8pin on the PSU side 😄 but this sounds like a nifty lil feature!

nope havent tested those yet. ive actually just reseated the cable i was using before (Seasonic) and the current imbalance is gone, crazy how that works. i got 3 our of the 5 ordered backup cables on hand, 2 still on the way. 3 of them Seasonic, 2 from Asus.

thats how i roll 😄 nah man, 100% hands off. WVPII totally provides peace of mind, let it run in the background and do its thing until an alarm gets triggered 🙂

ok so i figured since im having so much fun with RE Requiem and it draws an insane amount of wattage ill test my current GPU cable connection thoroughly and provide you the summary for comparison / reference sake. so total of 5 gaming sessions recorded with HWInfo64, threw out all data points below 95% gpu core load and anything below 600W for both total gpu power, as well as 12VHPWR only. that left me with approx. 7.5h of data with a monitoring frequency of 1s (27,215 data points total). the game was maxed out with RT and PT at 4K, no FG and DLSS set to Quality. as mentioned before im rocking the matrix vbios as a daily driver with a 24/7 stable OC of 34Gbps vRAM and +130 on the core, that gives me gaming clocks in the range of approx. 3060 Mhz +/- 30. ambient temps are currently quite high, were talking about 27-28C in my little "dad corner" 😄 gpu core is in the range of 68-73C under load, vRAM hotspot a tad higher at 70-76C and GPU hotspot approx. 85C on avg. with short spikes up to 93-94C (top 10% are in the range of 88-90C). FPS avg 102.9 1%% low 72.4 0.1% low 67.8 Total GPU Power avg 703W 10% high 761W 1% high 775W MAX 799W 12VHPWR Power avg 688W 10% high 744W 1% high 753W MAX 758W (interesting to see that as 12VHPWR wattage approaches the vbios limit at 800W, the gap to the total gpu power widens, thus the PCIe slot starts to draw more and more power, on avg. only 15W but the max spike is at 41W). Max Delta Current across 6 pins avg 1.06 A 10% high 1.99 A 1 % high 2.57 A MAX 3.3 A (stock setting for alarm in WVPII software is 4A) Max Delta Current across 6 pins (%) avg +11% 10% high +22% 1% high +29% MAX +35% (stock setting for alarm in WVPII software is +40%) this is how it should be, with even the absolute max individual data points still below the alarm threshold (which only comes into play if you get repeated, sequential limit breaches in a row, so a single data point spike aint enough to trigger it). this will provide a nice baseline once this cable inevitably gives out on me an ill need to test a fresh install / cable to compare 😄

so guys, seems like HWInfo is already on it with Blackwell hotspot readouts:

absolutely, planning to keep all 5 replacement cables for now. i managed to correct the current imbalance by reseating the original cable i had been using since the 4090. now the current is super even and good timing too! just finished playing black myth wukong and started with resident evil requiem: that game uses the full 800W envelope, absolutely insane! first time ive seen a game push the 5090 that high, also for temps: while im usually around low to mid 60 on avg temp, im now reaching high 60s to low 70s 😅 i think its time to have a look at the hotspot temps via the mods u linked above... yeah really a shame about the match vs. england, was the first world cup match i actually watched this time around 😄 youd think with all that new fancy tech, sensors inside the ball, VAR, etc. the game would be and feel more fair but somehow the opposite is true... 6C in mid july?! wth...i remember my time in trondheim in summer, me fully covered like an inuit while the natives were jumping around half naked at like 12C 😂

agreed just dont want one of the usual suspects to win AGAIN! argentina, spain, france, gtfo 😋 england, norway, switzerland, go right ahead!

btw wanted to leave this for bro @Papusan, RO NORGE! lets go, show them english whos boss! wouldnt mind to have a viking world champion 😁

yep i got three bottom 140mm fans blowing directly into the GPU fans, that in turn push the air up to the top of the case before its pushed out via the push/pull on the radiator. got another 140mm fan on top of the gpu backplate cooling RAM and SSDs directly, but also provides airflow to the WVPII / gpu connector in front of the fan. for context, gpu temps are in the low to mid 60s with the matrix vbios and max stable OC applied, with the temp sensor in the WVPII never having breached 60C. im more in the mid 50s with the inbuilt WVPII fan barely spinning at like 20%. im suspecting it has something to do with uneven cable pin seating, since im getting fluctuating results based on installs. just now i switched back to the original cable that i used for my 4090 previously (since the backup seems to be even worse) and currently running BMW as a stress test in the background: whaddayaknow, the six pins show super even current load again. while i switched out the cables i also reseated the WVPII and now used two different 8 pin sockets on the PSU. ill hold on to the 5 additional cables i ordered, can never have enough of these crappy cables it seems... ill let it run for a while now and analyse the results via HWInfo64. will report back. compared to smoking the 5090 which currently goes for like 4-4.5k € new i dont mind spending 110 bucks total on 5 cables to have in reserve LOL

your guess is as good as any. whatever the case may be, environmental conditions inside "normal" values shouldnt have such an immense impact. i mean, its not like were in the tropics / desert / arctic circle here...

nope thats with the matrix 800W vbios, although in BMW the wattage barely breaks 600W, maybe goes to max. 620-630 at most. seen much higher wattages in other titles or benchmarks. duuude im SO happy i got the WVPII, bringing those "invisible" failure points to my attention! edit: aight, ordered 5 different cables from 3 different sources, lets get our cable binning ON! lulz at least im glad to see that the variable really seems to be the cable and not the GPU, the WVPII or the PSU, that would suck even more. wish me luck guys!
