5070 Ti power limit, and overclocking

[mackerel]

I got a 5070 Ti at launch, and today put it through some testing with both overclocking and power limiting. The model is the MSI Ventus. In MSI afterburner it has 83-100% power limit, mem oc maxes out at +2000, and core has more adjustment range than I need.

For the following I tested at stock, with the lowest 83% power limit which is 250W, stock 300W. And the overclock I used was +2000 mem, +500 core. I did try +525 core but that crashed as soon as a benchmark ran. Driver 572.70. Windows 11. 4k resolution.

3DMark Steel Nomad - DX12: 6169 stock, 6930 OC (+12%), 6068 PL (-2%).
Monster Hunter Wilds Benchmark - Ultra, DLSS Quality, FG off: 70.7 stock, 80.2 OC (+13%). Didn't run PL as it never went over 250W so would be same as stock.
Black Myth Wukong Benchmark - Very High, DLSS 50%, FG and motion blur off: 70 stock, 78 OC (+13%). Didn't run PL as it never went over 250W so would be same as stock.
Final Fantasy XIV Dawntrail v1.1 Benchmark - Max: 89.9 stock, 100.5 OC (+12%), 89.4 PL (-1%).
Shadow of the Tomb Raider - Highest: 123 stock, 140 OC (+14%), 122 PL (-1%).
Watch Dogs Legion - Ultra, DX12: 78 stock, 87 OC (+12%), 77 PL (-1%).
Blender 4.3.0 - overall score: 7121 stock, 7951 OC (+12%). Didn't run PL as it never went over 250W so would be same as stock. Subscores scaled similarly.

If I wasn't so lazy I'd make a nice little chart!

This was quite consistent, everything was 11 to 13% faster with applying the overclock. I did find it interesting that several of these didn't even cross the 250W mark at stock, so they wouldn't be affected at minimum power limit. For those that did cross 250W when running, they were hardly impacted in performance typically 1% slower.

Typical core clocks were just under 2500, which is right were the nominal boost clock of 2482 sits. With the +500 core overclock, it was just under 3000. I wasn't seeing that limiting earlier for power. Going from 2500 to 3000 is +12%, which lines up with the OC benchmark results. VRAM clock went from 1750 to 2000 which is +14%. So that also scaled with the change in core and balance is maintained. TechPowerUp claimed to be able to set +3000 but I wonder how? That could help show if there is any further scaling from VRAM. It seems unlikely, as I did run stock core and +2000 mem on Steel Nomad for about +0.5% difference.

Have a chart and table. Hopefully more readable!

I saw somewhere that the memory clock is limited by the drivers/BIOS, so maybe a different card has a different limit, or it needs some unofficial drivers. I had no time to run anything on the RTX5070Ti. I just started the RTX5070, and it also has a 2000MHz limit for memory OC. The core has passed the Steel Nomad benchmark at 3090MHz so far.
I won't have the time for more tests until the weekend.

TechPowerUp said all their 5070 Ti models tested (including the one I have) were limited to +375 MHz (+3000 in Afterburner), and setting higher did not result in any further change. I'm only at +250 MHz (+2000). The 5070 Ti doesn't seem memory bandwidth limited anyway.

 

[Woomack]

I have a stock score of 6351 in Steel Nomad on my RTX5070Ti (it was my first run, actually). A stock score on my RTX4080 is around 6800.
The card boosts up to 2887MHz core and mem is standard at 1750MHz. 295W board power draw in the Steel Nomad benchmark.
The memory clock is also 2000MHz max. It's the Gigabyte RTX5070Ti AERO OC.

Edit:
I can set more than 2000MHz with Gigabyte software (which is terrible to use), so I guess something isn't right with the latest Afterburner.

On your Gigabyte it looks like they actually bothered to OC it somewhat. My MSI is barely factory OC at all, like the minimum they could do and still call it an OC model. On the plus side it doesn't look link mine suffers at all for it. I'm getting comparable core clocks to the few reviews I've seen out there. Will be interesting to see what stable core clock you can reach. I didn't note the exact number but I'm somewhere in 29xx, and +25 over my setting was clearly unstable.

Since it doesn't seem to be significantly impacted by VRAM speed I think I'll leave that alone for now. Bandwidth to compute ratio is only behind 5070, and better than anything Ada.

I guess all of those cards will OC about the same. It will be a matter of luck to a bit better chips, but probably +/-50MHz between various models. Power limits are not much different, too, and the memory clock is locked for all models. So the most important thing is if the cooler is quiet, the card doesn't have loud coil whine, and the ROPs are correct.
I will still try to check how far my card goes. Somehow, I doubt I will get more Nvidia cards, as all vendors make problems. Even this Gigabyte arrived already unpacked with some fingerprints and no protective foils on the cooler. We didn't even know what they sent for review until the package arrived.

I'm good on 2 of those 3. If I waited to check reviews the MSRP model would be sold out, so I knew there was a bit of a gamble in that I didn't know exactly what I was buying. The Ventus does get somewhat noisy at 300W. I don't know if they used a smaller cooler, or some reviews suggested it is just a more aggressive fan curve. At power limit core temps only reach around 65C so there's plenty of headroom. I'm debating if it is worth leaving the power limit at 83% or 250W, since in my limited testing so far it makes practically no difference, and the noise at 250W is pretty much nothing. Maybe that will become my summer setting. I'm curious what it would do at even lower power, but that is the low limit in MSI Afterburner.

Anyone knows when broken voltage slider gonna be fixed?

 

[Woomack]

Probably never, as these cards officially don't support voltage adjustments. You can force it in Afterburner using the curve tab, but it doesn't always work.

I was gonna say: "Let Earthdog do it: He LOVES charts!" But I see you already made one now.

Earthdog for charts... Kenrou for YouTube timestamps. That's the team.

 

[Newbiew]

Not even for 90 or 80?

 

[Woomack]

For the last five generations or so, all Nvidia cards have locked max voltages, except for Kingpin, Matrix, or whatever top-OC, highly overpriced cards. Most cards also have the same voltages, regardless of GPU. This is a part of Nvidia's warranty terms with graphics card manufacturers. Those top series were generally not covered by Nvidia warranty, but manufacturers covered all possible losses. Still, not so many of those cards were sold, and if there was any mechanical damage or visible overheating, then the user could lose a warranty.

 

[Newbiew]

What I meant was different. 40 series cards could be over volted from stock voltage,not by not much tho. There is a certain volt limit set by nv. As of now, it's bugged and 5k series gpu can't archive same max voltage as previous Gen

This is me speaking as a 3080 owner in the past.

I actually wrote this on another site and copy/pasted it over with minor edits. A little context doesn't hurt!

Oh so WE'RE getting the hand-me-downs now??

Who was there in the trenches when you really needed somebody?

Who was it that gave you four hundred bucks that one time?












...and what's his number?


............because my birthday's coming up in about ten days and I'm about 400 bucks shy of this guitar that guitar I want.

I'm sorry... what were we talking about?
