GTX Titan & 780 Ti VBios Overclocking Results

PC Games Hardware used Tech|Inferno's vbios (see my sig) to do some overclocking benchmarks and they found gains as high as 42% with an average hovering around 38%. Even 4K saw a 40% gain using a modded vbios: http://www.thedigitalhq.com/2013/11/11/geforce-gtx-titan-modded-vbios-overclocking-benchmarks/ The article is an old one from July but I haven't seen it posted anywhere else.

The difference between standard boost vs this type of vbios is it allows the clock to remain where you set it (like the good old days) and doesn't adjust based on power level or temperature. I run mine at 1150/1700 mhz daily for gaming in BF4 and it is smooth as butter.

I'm kind of surprised it's not faster than that @1265MHz. I'm just over 25K@1342Mhz, I was guessing it would be ~15% faster clock for clock. I wonder if Grooveriding has any scores in SLI from when both his cards would do 1400, bet that would be sitting right at 26K or above.
 
With all of these 780ti's hitting 1250+ in reference form, I can't wait to see what the aftermarket non reference PCB cards bring. They're apparently 12-15% faster than the plain jane 780ti out of box (videocardz.com has early benchmarks) and have OC headroom even on top of that. Should be interesting.
 
It's pretty amazing what a properly made vbios can do for a card like the Titan and 780/780 Ti. You gain up to 42% in performance with a steady state clock (consistent performance) and the temperature is perfectly manageable even on air. The PC Hardware graphs showed a single vbios OC'd Titan matching 680 SLI, that's beyond amazing when you consider theyr'e both 28 nm.

Then add in another 10-15% for 780 Ti and you can't be anything but impressed.

I don't think you'll see gains like that from a few more CC's.

Lavaheadache posted a firestrike of a 780ti at 1250 http://www.3dmark.com/3dm/1603043?, my GPU score was a touch higher with a 780 at 1400/7200, http://www.3dmark.com/fs/905929.

I think the only card worth looking at is a 780ti classified. Otherwise without voltage adjustments or perhaps cherry binned cards like a HOF 780ti, it is the same story as before with the comparison of aftermarket 780 cards to OC reference Titan.
 
I use the skyn3t vbios on my cards (780's), both run at 1241/1700 with no issues. I can play BF4 with max settings at 1440p and also set the resolution scaling to 150% and still keep 60fps+. Temps top out around 85c. These are both reference cards btw.

What voltage do you have yours set at?

The average overclock of a 780 Ti is already beyond what Titan can get with both being on air. On water they may get closer but I can't get anywhere close to 1900 MHz on memory or 1300 MHz core. Even those on water rarely get near that.

yup the 780's sure do fly when you give them virtually unlimited power target and 1.212volts

Here's my 780 Ti:

Though I have settled for 1.187 volts and 1200MHz core, 7.6GHz Mem for every day use. Don't feel like frying this thing just yet 😛

Pretty good score but I see you have 1440p monitor but you benched it at 1080p. Why was it done like that?

that's a lot more volts than I need for 1200. I'm at 1.1

I can probably get away with less. I gamed at 1200 with 1.01 for about 25 mins before crashing and just stuck it at 1.1 cause I didn't feel like tinkering with it.

1.212v with the LLC mod. They can actually finish valley runs at 1306 if i boost them to 1.25v

Have you tried 3DMark Vantage with those settings? I've found that it stresses my GPU OC more than any other benchmark and if it passes Vantage, everything else passes too.
 
Push that 2600k. My 2700k is good for 4.8 I just don't like to beat the crap pit of it for no reason and run it at 4.6.

yeah i have been lowering it slowly. currently at 1.125 for 1200mhz. quite impressive tbh. my old 780's took 1.2 for 1200mhz.
 
Thanks for the info on this! I've never been a big fan of the shift towards boost clocks.

Currently have my MSI GTX 780 Gaming set to 1250MHz on the core. I can only get the memory from 6GHz to 6.5GHz. The cooler is amazing on this thing. Wish I could push it even further!
 
Help me out here.

I'm running the sky3t bios on my 780GTX SC ACX. At 1.212 my core is 1241 and mem is 7000mhz.

I keep reading that with the LLC mod, I can get better clock speeds on the core but I don't know how that works in conjunction with the skyn3t bios. Any ideas?

I'm basically wondering if my core is maxed out at 1240 or if I'm power draw limited at this point.

LLC mod should stabilize your variance but I think it's geared for higher volts like 1.3+. I haven't seen it make much of a difference at 1.212v. Try svl7's vbios.
 
Thanks Joker. Doesn't seem like the svl7 goes much higher on the power draw than what I currently have.

I'm just messing around while my Ti step up gets approved. Pretty happy with 1240/7000 performance so far. Will be a bit annoyed if my Ti is an over clocking dud though 🙁
