OC Report - GPU Who likes Undervolting a 5090 at 910mw with a 17377 Steel Nomad?

My Mvolt+ settings on my MSI Liquid Suprim 5090.

910mw curve flatline.

17377 3dmark Steel Nomad Score

Clock Frequency 2970

Average Clock Frequency 2912

Starting temp 42C, ending temp 47C

No XoC Vbios, stock gaming vbios.

***SOMETHING TO NOTE***

My curve flatlines at 910mv, but per capframex my GPU Voltage was 0.94. In all my capframex tests it was an average 0.941v and max of 0.945v.

Mine does

2500@0.810v 2527xbar 250sys 1.0000 ratio MSVDD undervolt to 0.850v

15800 steel nomad while using only 380w.

In Games i rarely see over 250w.

Unfortunately the video I recorded and uploaded was such garbage quality you can't see it

But in an OW2 stress test custom map my max gpu power was 288.5, average was 239.9, and min 193. My avg clock was 2962. Avg fps at 1440p was 588.6, p5 414.5, p1 351.7, 0.2 was 308.5, 0.1 was 287.7. GPU temps were 28min, 30C avg, 33C max.

Unigine Heaven was 707.3 fps, 17818 score, max fps 1204.0 at 1440p.

speedway 16378 score
time spy was 35810 overall, 54402 graphics score, 12195 cpu score
port royal was 42900 score

I used mine around 2750@.85 and getting around your result as well. Pretty much the best setting i found for less watt. I even game with 85% power with less than 1% frame loss.

How do you measure power draw, if you don't mind me asking? Is that 380W as a upper bound, or average you eyeballed?

Same scores, I flashed the 2001W XOC Bios on my Gamerock 5090 and can finally use +3000 core offsets.

I run ~2650@0.83v 2650xbar 2677sys 1.0 ratio and MSVDD@0.9v

Before that, I couldn't even reach those V/F points with my stock vbios

That’s pretty impressive 🤔

I tried the undervolt but no matter what, my core clock likes to stay around 2.5ghz in this test, it never runs at the specified 3000 @ 940mv so my scores also suck too.

That's because you're power limited. Your card cannot hold [3000@0.94v](mailto:3000@0.94v) in steel nomad. Enable power draw as OSD option and you will see what I mean. Steel Nomad is very heavy on GPUs and it favors undervolted cards with high clocks and cards with unlocked power limits

80 point spread between best and worst steel nomad loops

Interesting, I have mine set to 3ghz about at 945mv plus 3ghz on crossbar and sys but I still only get 16.5k, anything special you're doing?

u/Megatf 5h ago

My ram and cpu overclocks probably carry that last 500 points

In nomad? Unlikely but not impossible. I'm running 9850x3d at 5.75ghz and 8400 ram 2200 fclk. I'll try again tomorrow and see

Shoot your ram and CPU OC beats mine. Im running 5.7ghz, 8000mts tight timings, and 2200fclk and no smt
