So guys, are you recommending to buy this video card rigthnow or better wait until bugs been repair on new stocks? i have reading some bad stuff trottling or something.
post #2263 of 28134
I still have a ton of testing to do on my second Titan, as well as benches to run on my W/C CF 7970 setup before I even drain the loop and install these Titans in my main rig (testing them out on my 2600K folding rig at the moment). I also have to do a bunch of filming for my Youtube channel (already did the unboxing but still have to unbox the blocks, do the installation guide, and performance vids for 7970 vs Titan with single and dual card results as well as comparison testing between a single Titan and a 580 Lightning that I'm doing separately on request). I wish this was my actual job so I could have the time to do it all! biggrin.gif

I cannot believe the will power you have to be able to resist the Titan.

Get them now! Even with throttling a few mhz, they still beat the hell out of +1400mhz 680's. They bully 680s so bad, they take their lunch money, shove 'em in their locker, and bang their girlfriend wink.gif

It sounds like 680s might even be doing the same thing in certain circumstances. It could just be a driver issue. I'm not too worried about it. Worst case scenario EVGA will release a bios update. I doubt that it'll come to that.

So I removed my 1st Titan and installed my 2nd Titan to do some testing. I used my same settings as my other card for initial tests as follows:

Power Target : 106 Prioritized
Temp Target : 85c
Core : +150mhz
Memory : +200mhz

Fan Set to a 1:1 Temp:Fan Speed
Votage Set to max +38

So I do my first run of Heaven and notice that this Titan boosts to a higher clock at 1176mhz. It also uses the full voltage of 1.200v which my other Titan only does 1.187. This Titan TDP also goes above 100% in Heaven a lot more than the other Titan. However, it does throttle a little and the voltage also drops a little. At times speed dropped to 1167, 1150, 1130...voltage at these times also dropped to 1.187 and 1.167. But no massive drops.

However the card did crash as well only half way through Heaven. Rebooting and starting over I decided to remove the Memory OC. Pretty much the same results for boosts speeds and the small drops, but it did crash as well after 2 loops of Heaven. I am on the 3rd try right now with Core Offset set to +140 vs. +150 and so far no issues. I do see like the tests before that the TDP is going to 100 and at times 103 which the other Titan did not. Voltage is also hitting the 1.200v ceiling and the card is boosting to 1163mhz. Drops do happen, it mostly stays at the 1163mhz/1.200v, but does go to 1150mhz/1.187v and 1137Mhz/1.175v.

In comparison, my first Titan in Heaven never goes above 1150mhz/1.187v but it sustains that speed/voltage no matter what in Heaven and does not drop. It also caps the TDP between 93-98%. So in a nutshell:

Titan 1: Max boost clock with a +150 to the Core in Heaven = 1.150mhz/Max Voltage 1.187 No Throttling
Titan 2: Max boost clock with a +140 to the Core in Heaven = 1.163mhz/Max Voltage 1.200 with some throttling to 1150mhz/1.187v, 1137mhz/1.175v.

Titan 1: Max TDP in Heaven hits 98%
Titan 2: Max TDP in Heaven hits 104%

Temps are with the same threshold for both cards.

So in review, Titan 1 can have a +10mhz more to the Core given to it, but Titan 2 can boost +13mhz with -10mhz to the Core in Precision. Titan 2 can hit a higher TDP in Heaven vs. Titan 1. So it seems like my Titan 2 is a bit better with boost than Titan 1, but Titan 1 stays locked down at 1150mhz without any drops in Heaven. What I don't understand is why my Titan 1 card cannot use 1.200v, it maxes at 1.187.

So does this make sense to anyone else on how one card can go to a higher votlage even though both are being fed the max +38 within Precision?

Also, I am on run number 5 of Heaven and Titan 2 is still going strong without a crash. Will report back if it does crash. If not, onto Crysis 3 with Titan 2 to see if there is any throttling. With Titan 1 it stays locked at 1150mhz.

I think this just proves that not all Titans are created equal. They all don't have the same headroom. As to why one goes to 1.2 while the other doesn't, that could be hardware related limitations as well. I somehow doubt Nvidia will have anything to say as long as the cards work at advertised speeds, which they do for the most part I guess.

Well that's true for any card. I just wish we could go back to the Fermi way of overclocking. What the hell was so wrong with that? Set a voltage and a clock speed and it either runs or it crashes. this boost crap is devastating for overclockers...
post #2269 of 28134
Got my GTX TITAN. Love the card thus far. Was able to push it to roughly around 2050/3075 with my AC running a little harder, but decided to drop it to a more easily manageable 1176/3055 with 1.200V till I can acquire a water block for it. biggrin.gif

Just an update....

My 2nd Titan is still holding strong in Heaven and no crash as of yet. I am going to let it run through dinner and then increase memory +100. Titan 1 was able to do +200 on the memory with a +150 on the core. On Titan 2 +150 on Core and +200 on memory was crash city.

What sucks about doing all this testing is that I have to do it all over again tomorow when I install my blocks on both cards and them finally have them together in SLI. But I am more curious as to how they react to water and running sub-40c.
