Posted in the over clocking thread but no replies as yet, just wondering, I have taken a 780ti to 1200 base on stock volts, seems totally stable, it is EK blocked, is this about standard for an OC on water?

Cheers guys

1200Mhz base clock is pretty awesome. I've had two 780 Ti's and none have come close to that. Both on air though.
What do they actually run at?
 
They boost to about 1220 > 1230

IM running it 24/7 at the OC :D

Temps max at 54 degrees... When I stick another 100mhz on the mem I have seen some instability.
 
mine maxes out at 1230mhz boost/ 225mhz on memory on stock volts adding +75mv does nothing to help me gain a better overclock

I waited and seen the Titan Black launch the other day, not really ideal so ordered a EVGA 780Ti SC which arrived just after 1pm today.

I had PC ready to pop it in (drivers removed/cleaned out etc.).

ASIC of 72.3 (my EVGA 680 FTW 4GB was 75-76 AFAIR).

Both are Exhaust Blower design, I do not like/want air all over case even though the NZXT 630 has good airflow.

Installed the newest drivers and at stock voltage with power set to 106 and fan at auto had 1200+ stable in Heaven (may have gone higher but I never tried as learning new settings).

Fan at 100% is far quieter than the 680 at 100% and can go as low as 26%.

The card is solid with no sagging/twisting as you can see when fitting to Mobo as its metal, normally you have to hold a card level and tighten the screws but this thing is straight as a die and lines up with the case holes without lifting it

Need to mess with settings to see how far it can go with more volts etc. and glad to report no coil whine even in MSI Kombustor which does lower clocks but hits 99% usage.

I prefer EVGA Precision but OCD stats do not work in 64bit games for time being.

Should get about twice the FPS that I got it many games than a 670/680 (not sure if that's against 2GB or 4GB models).

Ideally I feel Nvidia should have made this card a 512bit bus and 4GB of VRam as I do play at 1440p.

Overall very happy so far.

Ah I thought it may have been 1300Mhz :) Still decent though, anything over 1200Mhz is nice.
Mine can run at 1250Mhz with auto fan which I'm fairly happy with.

i'll share with my experiences of 780ti overclocking, plus some general stuff.

1. Volts are Hardware locked to 1.212 on anything other than the classified, and only with skynets bios, no softmod will unlock the voltage any further, Afterburner will show more on the voltage slider but it will do nothing.

2. Voltage control doesnt work properly in Afterburner.

3. EVGA precision X for better or for worse is the only real option for 780 overclocking right now if you want more volts.

4. LLC hack doesnt work

5. In my experience they overclock MUCH better under water.

6. ASIC values mean nothing , on any card .....

7.Heaven, Valley , and 3dmark are a very poor test for stability, I have found that non of these stress the card anywhere near as much as (For example) Tomb Raider , Crysis 3 , or BF4.

My 780ti will loop heaven all day long at 1300+ but reset the driver after a short time in games , i have settled for a modest 1279/[email protected] with a power limit of 130% and thats stable 24/7 with no issues

3GB is more than enough for 1440P gaming :) so is the bandwidth ;)
 
Bet some games will need more soon if not a few now with mods, esp if you plan to SLI.#

I would have paid a fair price more for a 4GB-6GB Ti but not the Black price unless I was using the DP for a living.

I went backwards from 4GB to 3GB but wider bus, its better to have a little headroom than be on limits if you plan to keep it a while.

Luckily for me my 1440p is less than yours as its 2304x1440p (if you can work that out). ;-)
 
Nah.

3GB will be fine for at least the entirety of this year. At least at 1440P and below.

I've tried very hard to blow VRAM limits. MSAA 8X in AC4 @ 1440P and a few other games, I can hit over 3GB but there are no walls being hit. Games are very cache efficient these days. Plus with any luck, tiled resources in DX 11.2 should help massively if it hopefully gets implemented.
 
Some keep a card longer than a year and I think if a card has more VRam a game will try and use.

Cant really explain it right but a game will try not saturate VRam to 100% as it will effect performance but if you give it more it will eat into that Vram.
 
Of course it will, it will cache as much as it can, but performance doesn't seem to be effected. I can still get faster frames in BF4 in DX than most 290 users, and their VRAM usage can extend over 3GB. There's also a lot of stuff stored in memory that doesn't need to be I'd imagine. Bioshock Infinite can saturate my VRAM, and that game is in no way shape or form capable of using all of it at once lol.

There's obviously a lot to it that isn't clear to the end user. And also, I appreciate that a year isn't that long to some people as well. Especially with a £500 tag :D
 
Thanks for all the feedback guys, much better than in the OC thread.. For the record asic quality is 71.2

Ive rolled the OC down to 1100 mhz as im running in an MITX case and cpu and GPU are sharing one (very large) 240mm rad so dont want to go too ott..

Does seem like it like to OC though, I may add another RAD to the back of the case and push it all a bit harder, a project for the future though :D
 
Is that the fast dirty trick to get idea of a good sample and is that with voltage at max without bios edit and fan speed at what?
