30xx Series Founders Edition

[MartinPrince]

Is there any utility that can automagically do that for me? Or, is it done by trial and error?

As far as I'm aware MSI Afterburner is what everybody uses. It's relatively simple and there are lots of video instructions on YouTube.

Here is a good video about it.
I have my 3080 undervolted to 0.9v at 1920-1930mhz depending on a game.
And it keeps those clocks no matter what (have my power limit set to 110% as well for when it needs it).
Uses much less power and produces less heat on average and clocks are higher and more stable than stock.

Happy to see the price of the 3080 Ti FE has not dropped like soe other cards in recent times. Makes me feel like I got the money's worth back when I got one at RRP!

Does anyone else think the RTX 3080 10GB prices are being kept artificially high, due to the fact that the RTX 3070 TI is still widely available (and maybe still in production)? Therefore, this is the card that occupies the £600-£700 market segment, even though it's not much faster than the RTX 3070 - it's the full version of the GA104 die, with about 4% more shading units, the same amount of VRAM and about 2.6% higher boost clocks.

In a more ideal market, they would cancel the RTX 3070 TI, increase production of the RTX 3080 and sell it for £600-£700, and not waste the GDDR6X VRAM on the lower end GA104 die GPUs. Not enough competition from AMD, this time around.

3080 10Gb is much faster than 3070 at 4K, 3080 10Gb has comparable performance to 3090

 

[g67575]

Afraid I don't see your point. The RTX 3070 has a lower per frame at 1080p and 4K resolutions, than the 3080.

But for the FE cards, the RTX 3070 TI has a slightly lower cost per frame than the 3080. But, I consider the AIB models to be overpriced.

 

[stooeh]

Are you asking if the AIB cards are artificially high?

 

[g67575]

I'm saying that the RTX 3070 TI is effectively inflating the prices of the RTX 3080 by occupying this price point, which is what happens when you have too many product variants that are too similar (The RTX 3070 is too similar to the RTX 3070 TI in performance). The same thing happens when they sell slightly overclocked variants of graphics cards, then put lots of silly sounding branding names like 'SUPRIM' in the title.

Some RTX 3070s might even be able to keep up with the RTX 3070 TI FE, as the theoretical performance is a bit higher, except for the VRAM bandwidth (which doesn't benefit performance in every case):

Had to wait to get my card due to a slow dispatch from CEX, but it arrived today and the card works fine so far

I used Geforce Experience's overclocking s/w to limit the power to 90%, and that keeps the clock rates at 1710mhz or above in games (tested in TW: WHIII at 4K resolution), which is the boost clock this card and the FE are rated for.

This keeps the VRAM temps below 95 Celsius, which is apparently the max recommended temp for GDDR6X VRAM (apparently damage can occur at around 120 degrees Celsius).

Is it possible to undervolt the GPU, and still ensure the card always operates at the rated boost clock of 1710mhz?

I noticed that when the voltage dips from 1v to 0.9v, so do the clock rate.

 

[SaBBz]

Those clocks seem very low. My undervolt is 1965mhz @ 0.9v. YouTube has a number of decent guides for undervolting the 3080.

 

[g67575]

Yup, I'm testing a custom voltage curve with Afterburner now, it seems to be working well, and keeps the clock rate and voltage steady.

I'll try bumping up the clock rate.

 

[g67575]

Got a crash with the GPU clocked at 1900mhz (fairly sure it was graphics related), with 0.9v. Seems alright so far with 1800mhz at 0.9v.

I've noticed that my motherboard temp has gone up quite a bit, and the chassis fans are running at higher speeds. But I did set up the fan profiles again in my BIOS recently.

[g67575]

I've got it running at ~1800mhz at 0.85v. I'll probably stick with that, assuming it's stable. Power draw is less than 300w under load, around 60w more than the RTX 3070.

 

[SaBBz]

I found the best thing to use for stability testing is Quake 2 RTX as it’s very intensive.

 

[stooeh]

Metro Exodus Enhanced also good for checking for instabilities imo.

 

[g67575]

Got a crash in Quake RTX at 4K resolution, this game seems to eat more power than Warhammer III at 4K, I assume due to using the cards ray tracing hw.

Hopefully I can just lower the clock speed a little.

 

[g67575]

I think I am going to settle with a clock speed of 1710mhz, as this allows me to reduce the voltage to 0.825v. This keeps the VRAM temps below 95c even in Quake RTX.

 

[g67575]

If the VRAM temps are consistently higher than 95c, is this likely to reduce the lifespan of the GDDR6X VRAM, and eventually kill the card?

You have to wonder if Nvidia even cares if cards fail after 2-3 years of usage...

Swapping pads will drop a chunk out of that VRAM temp.
