As long as we're talking about air cooling or plain water cooling, less voltage could yield higher frequencies than higher voltage when

Can anyone confirm if this is normal, there is a scene in time spy bench2 in where you see those futuristic rifles a few seconds from the start which power limits my card, I see recorded in MSI AB as 119%, it will throttle my core from 2012Mhz down to 1960+, the core voltage used is 1.025 and + 500Mhz on mem.. this is with the benchmark running on max sliders ( custom ) and 4k resolution.. seems like 1080Ti is power starved?

Founders 1080ti Vram overclocking causing shutdowns, like power failure shutdowns, quick and fast. FYI Shunt moded

Got G10kraken on it with closed loop corsair cooler, have little heatsinks on Ram and Vrm and there is that little fan. Even added fans and put copper sheet on the back of the card right on the other side of ram sticks, which gets hot to the touch.

How likely is it that Vram overclock is causing shutdowns. Seems like Vram's VRM or and the Vram itself might be too hot, or VRM exceeding its Amp limits. We know what ever a rating for VRM is, it becomes less and less with heat. I got cooling on it but, just wanted to know how likely. Gtx 1080 ti Founders 1.000v on core for 1999 in game and Insane vram clocks. 770-790 + Ram overclock and yes it scales performance, haven't found the sweet spot before I stop getting Gains lol, I powerr limit before it. I get 11,000+ on timespy Graphics score......

I know very weird, the other card I had 1080ti founders as well couldn't even 450+ on vram and would crash, this one can only do 800+ on Vram with fans ontop and below it at max rpm. Even then sometimes its automatic shutdown, so its all power related and heat.

Yeah its some insane Vram clocking i. Gotta treat it like the GPU die itself frown.gif Btw I'm pretty sure im peaking 400watt when I do 2088-2062core +770ish+ Vram

VRAM overclocking on the 1080Ti is weird, I get the following results on TimeSpy Bench1 and 2. No crashing no artifacts. Though i sense something else is wrong/missing or is it really common to get those +850 stable ?


+500
68.15
61.67

+600
68.47
61.92

+700
68.46
62.09

+750
68.92
62.10

+800
68.92
61.75

+850
69.16
62.33


I did not try +900

Was hopping Volta to be revolution...
https://www.3dmark.com/compare/fs/14415213/fs/14382680#
It's fast but comparing my result to the 2Ghz/1000 OCed TitanV running the same platform in FS only 10% difference on average for 4 times the value ...let's hope the gaming model will be better performance and OCing wise thumb.gif
In TS on the other hand 2100Mhz/1050 TitanV is 40% better than 1080ti@2100 tongue.gif

@EarlZ yeah, well like I suggested before there's a limit to where you see performance, and beyond is just extra power, heat, and even decrease performance. To me, whats surprising is the constant linear performance increase with no matter what clock I use on Vram, 800 is usually autoshut down, If I had a real water block I could keep testing but lol it would go well beyond 400watt. http://www.3dmark.com/spy/2922992 that's as far as I can go with my current cooling, card hasnt shown any sign of hitting Vram scaling limit, power gives out.

@DStealth, yes Volta disappointing as of now and pretty much overall on price obviously and even performance. It's only 15 % faster than gtx1080ti in dx11, and where it looks to be a game changer is the field Nvidia previously struggled on, or kinda stayed staggered on, the low API stuff, DX12/Vulkan. Where AMD has huge leaps and Nvidia often performed worse than it's dx11. The Titan V up to 35% than a Gtx1080ti, on those low APIs. The first Gtx Titan for Pascal came out early too, so this Titan V looks like the next generation of what we had for Pascal's first Titan, the thing though is 2.5x the price of Pascals first Titan.

This isn't surprising, the price that is. It's a huge die, that reduces profit, more can go wrong, then you add HMB2.... speaks for itself, I reckon there's a good chance the consumer cards will break records in high pricing as well, 10 % is pretty bad jump lol. One thing looks clear though, they will overclock like the legendary Maxwell generation, where 20% overclocking was average, if you were willing to mod.

Although we can only expect further lockdown in bios and soft mods, like every new generation gets worse and worse for our tweaking freedom. So im sure it wont allow voltage mod through software hax, nor bios edit, like Maxwell allowed frown.gif. But even without that, the overclocking reviews are looking to be insane.

I honestly wont be upgrading though, this card can do everything I need, keeps high frames in competitive games, keeps smooth frames in 4k games, honestly dont need anything higher, but who knows ^^ tongue.gif

Whats a good benchmark aside from time spy that is suitable to validate VRAM oc, one that should be extremely reliable and can show the slightest performance gain or loss?

Maybe the Titan V is CPU bottlenecked in Fire Strike vs. Time Spy. wink.gif

Probably a benchmark that has a 4K option.
