@Lew Zealand

Sorry for bad English, it's my 3rd lannich...

;D

2300 MHz at 132W seems considerably lower power usage than mine. I will retest at that speed this evening and undervolt until it fails to see what I get. I believe you're in the Demo portion of the benchmark there, which I usually skip. If you want to match the worst case scenario, you can do a custom run looping just the Graphics 2 section and see what your max wattage is. I'll run the Demo portion to see how it compares to your numbers there.

I ran the Demo, then the Part I, then the Part II. 130 to 140 W, averaging 135 or so W. Peak wattage was 142 W if I remember it correctly.

this evening

Are you from NZ? I mean, I don't know where you are and when your evening starts. It's 01:14 am for me and I'm going to snooze. Have a nice day anyway.

Are my temperatures with rx 6750 xt normal? mainly the vrm temps

A bit hot but nothing really bad. Undervolt it to 1100...1135 mV (depending on how lucky you are in silicon lottery), lower the max GPU clock by ~100 MHz and call it a day. This alone will make your GPU way lower on wattage. You'll also lose up to 2% performance but better slow than sorry (yet my recommendations are mostly paranoia than the real threat because your temps are almost 20C behind dangerous ones).

Yep, they're fine. Although, your card doesn't seem to be using its full power. Mine runs with a 200 W chip power draw under full load (it's a reference model).

Result A (most impressive energy efficiency). Settings what we agreed upon but tried -71 mV offset. Mean wattage: 135. Peak wattage: 142.

Result B (save energy without noticeable performance losses). 2477 to 2577 MHz. -71 mV offset. Mean wattage: 167. Peak wattage: 173.

Result C (OC/UV). 2625 to 2725 MHz. -71 mV offset. Mean wattage: 202. Peak wattage: 208.

Result D (XOC/UV). 2700 to 2800 MHz. -71 mV offset. Power limit: +15%. Mean wattage: N/A. Peak wattage: N/A. Reason: crash.
Result E (XOC/69UV). 2675 to 2775 MHz. -69 mV offset. Power limit: +15%. Mean wattage: 211. Peak wattage: 226.

Why do you think that might be? Could it be bottlenecked by my CPU?Ryzen 5 3600

3dmark time spy.Is yours at basic settings on adrenaline?

By the way which value on hwinfo shows the power used?PPT limit is 210 is that not normal?

Can anyone share me their HW info page with Rx 6750xt.It states that my power limit is 210w.Shouldnt it be 250?

Why is my power capped at 210 instead of 250?

OC/UV max performance, Power Limit +15%, 214W (pegged at Max)
Cores 2380-2470 MHz (cores set to 2676 MHz in Adrenaline, -0.100V offset)
Memory 2150 MHz
0.987-1.118V with brief excursions

Stock OOB performance, default Power Limit +0%, 186W (pegged at Max)
Cores 2160-2250 MHz (cores set to 2609 MHz in Adr, no V offset)
Memory 2000 MHz
1.006-1.056V with brief excursions

Max Efficiency settings, Power Limit +15%, 141-147W
Cores 2011-2063 MHz (cores set to 2177 MHz in Adr, -0.063V offset)
Memory 2130 MHz
0.887V fixed, no excursions because this is the minimum voltage the GPU runs at under load, hence max efficiency

Matching your 2300 MHz setting, Power Limit +15%, 180-191W
Cores 2294-2326 MHz (cores set to 2458 MHz in Adr, pretty good for first guess eh? -0.075V offset)
Memory 2130 MHz
1.006V fixed, no excursions

Huh my graphics score seems higher than yours, not sure why. Power usage is super higher, though!

That's probably enough but you can see the crap sample trend. My 6800 XT is good and my 6600 XT is great, but this one...

 

[Ruru]

Still runs at 40+ fps and as we know, Crysis isn't a fast-paced game. I hella enjoy these.

4K SMAA 1TX on the other settings.

 

[AusWolf]

3dmark time spy.Is yours at basic settings on adrenaline?

All basic, except for enhanced sync enabled. Time Spy should stress it enough to use full power.

By the way which value on hwinfo shows the power used?PPT limit is 210 is that not normal?

Can anyone share me their HW info page with Rx 6750xt.It states that my power limit is 210w.Shouldnt it be 250?

It's absolutely normal. AMD's official TDP is for the whole card, but the power limit you see in HWinfo is for the GPU chip only. The default limit on my reference card is 200 W.

What we'll have to figure out is why your card doesn't max out its power limit in Time Spy.

 

[Macro Device]

this one...

Yeah. Busted.

I assume it's being bottlenecked.I got a Ryzen 5 3600 and a single stick of ram

It shouldn't be bottlenecked in Time Spy. But let's go with that theory. Can you run Superposition and check your power readings? Superposition really isn't bottlenecked by anything other than your GPU.

Ran superposition.Scored a 7126 on extreme and gpu ppt was at 188watts

Your score is spot on, but that PPT is a bit low. Is your card running at stock?

 

[jayjr1105]

Hey guys, have a 6750xt MSI Mech here and I repasted GPU and used thermal putty on VRAM today and trying to stretch it's legs a bit but PPT seems to be stuck at 210w max. Afterburner and Adrenaline won't let me go higher than 100% power. I was under the impression this was a 240-250w card. Am I missing something?

210 W is for your GPU chip only. The official TDP of 250 W is for the whole card. The 6750 XT doesn't measure total board power, so the only thing you have control over is the GPU. In other words: you're fine.

I used the more power tool to raise it to 240. I've seen other 6750's be able to raise the PPT limit past 100% in adrenaline but not this one for some reason. Temps with Furmark still in the mid 70's with 90c hotspot. A lot of the 6700/6750's are overcooled and hamstrung by this.

 

[Macro Device]

Spoiler: My 6700 XT mutated once again

Certified ghetto. The central fan was too big for my faulty cover case and I was forced to cut it with a hot knife.

Yes everything is at stock settings on adrenaline.Could it have something to do with my old mobo?It has a pcie 3.0 slot instead of 4 ı think.(b450m s2h)

I'm not sure. How about your power supply? What PPT limit does HWinfo show?

Max power limits are up to the GPU vendor to set in the VBIOS, I assume.

I actually undid it and set the power % slider to -6 - +15 from the default -6 - 0. Much easier to adjust on the fly.

 

[jayjr1105]

Factory paste removed and replaced with a PCM-1 phase change pad. Also used thermal putty for VRAM. How does it look with a moderate OC after 20 min of furmark?
