Underclocking to overclock my TITAN X Pascal

[ComansoRowlett]

Hello!

I'm sure some of you have heard by now that the TITAN XP chokes on power pretty hard when overclocking. So I was wondering, is it worth underclocking my GDDR5X a little to compensate for the core so I can overclock that further? Or won't I see any difference/lose performance?

EDIT: I can get around 1950MHz on the core while the memory is down clocked to 4513 (9026 effective). While with ordinary overclocking I'm running around 1823MHz (done automatically by GPU boost 3.0)

EXTRA EDIT: With further testing, I've found I get 175fps with the extra overclock (and undervolted gddr5x) in Unigine, while at stock (1823MHz core) I get 164fps but I don't know if this data can be put towards games.

It will depend on what you're using the GPU for. Some software will react very well to memory overclock. Like the Unigine benchmarks.

You'll just have to test your games and / or benchmarks you want to run, to find out the happy medium for your GPU.

That said....a memory overclock isn't going to cause a power limit problem as much as the increased voltage from increasing the core. I really don't think you'll notice much of a difference....but it's worth a shot.

G'luck

Thanks for your reply Vellinious! It seems at the moment, I do get quite a bit of extra power by taking a hit of 500Mhz (1000 effective) which is great actually and I do see fps improvements in games which don't eat up massive amount of Vram (over 5000 I do start too though). I guess I'll need to wait for a custom bios so I can up the voltage/power limit a bit, that'll really help me out as I've worked out the core can actually go to 2050 with the right amount of power stable alongside a memory overclock of 500mhz extra at least (11000). Any idea as to when that'll happen? I know it's a struggle to get it done, but it's easily with the 1080's due to being able to just flash a different bios from a partner card to yours as an example. I do have watercooling so temps aren't an issue.

Temps are always an issue with boost 3.0. There are layers. 25c, 35, 50c....all layers where clocks drop to reduce heat. You might fit comfortably in between the 25c and 35c layer, where the only one you hit is the one at 25c or something, and that just raises the voltage a step and can keep the same clock, but...it's there.

I'm beginning to think we may not get a pascal bios editor. Which really sucks, but.....eh, Ngreedia....

I had a Titan X Pascal....super powerful card, but, the power limit throttling was too much for me to handle, so I sold it and went with 2 x 1080 FTWs instead.

Yeah, it saddens me how I did have a 1080 FE which overclocked pretty well so really I should of given it a brother but I thought single card was the way to go... Boy was I wrong, I really wish I got 1080 SLI instead... I have even more of an issue because my hybrid has the fan and pump connected to the PCB which will be sucking up most of the power too 🙁 Apparently there is a power shunt mod out there, where you put liquid metal on 2 of the resistor to increase the power target by about 30% but one it's risky and 2 it doesn't allow you to add any increased voltage (1.093 as you know). If we don't get a bios editor, then all this potential I have for this card will be wasted... I sure hope Nvidia don't do the same thing for Volta and not equip the TITAN with a better power delivery (8+8 pin with a 5% power target extra (125% overall) would even make me happier).

Also forgot to mention I'm actually around the 35-50C range, I never go above 50C though which I'm happy about. I think it's actually quite silly those checks are in place, because as you know it has about 34C more to go above the 50C mark or 40 more if you increase the temperature limit (which I have to 90).

I get 2088mhz on the core with overclock and 5702mhz on the memory (11404mhz effective) I am water cooling with a heatkiller IV waterclock 29c idle and 44c under load after 2 hrs My core voltage is +100 power target 120% temp at 90c limit ( although 44c is far cry from it) +195 on the core +700 on the memory. It hits a voltage limit of 1.093v (like all pascal cards do) so the next step is getting more voltage. if your still air cooling and trying to hold a stable clock good luck gpu boost 3.0 will totally mess with you. before with air cooling it would only do 2050mhz and as temps rose it would downloack it 1975mhz with an aggressive fan profile.

Temps are key. The colder you get it, the higher it'll boost.
