I even changed my mind on the titans after I already bought them and put them up for auction, after a couple days I couldn't take it anymore and just pulled the auctions and opened them up and installed them last night.

I'm now trying to muster the willpower to not waste my budget on 3770k and wait until haswell/haswell-e/ib-e. 3770k is so cheap I doubt I will be able to hold out. whistle.gif

I wouldn't get a 3770K with two Titans. Try your best to hold out, if not then go 3930K.... These babies need all the CPU Mustard they can get

Prioritize TDP. Sorry, had to step away for a bit. Since my last post about an hour ago, Unigine has been running and no crash at +150 on the core. Clocks have stayed rock solid with not one drop at 1150mhz. smile.gif

I got up to +181 on my single Titan. Anything further and it crashed on me. Can't get anywhere close to that on SLI.

I'm on SuperClocked so +110 is roughly same as +150 on yours. It throttles down to 1137 quite quickly, and +110 is not stable on my card. If I use +90 (1163MHz with no throttling), I get the same 1100MHz after throttle.

Sadly, no change for me.

Yes, prioritize TDP. For ****s and giggles, mind doing the test again, but use Precision X instead. I am wondering if it is Afterburner that may be causing something.

Damn that is pretty good. I cannot get past +150 on mine and that is with setting the voltage to the max. Heat has been relatively a mute point regardless of voltage setting. I am running 1-2c hotter at the max voltage vs. default/standard voltage. But to get +181 is pretty impressive. I have not hooked up my 2nd card yet, going to do that in a bit.

BTW...Your Smokey over at NeoGaf right?

wait a minute.... what unigine r u running? Valley or 4.0 ?

Because i just ran your exact settings....... still throttles minor

I think you need to use valley cause by the sounds of things...youre using 4.0 or 3.0 w/e..
Its in valley that we see throttle

Well +150 on a normal Titan will boost up to 1202 if my math is correct. You are throttling, it's just throttling from a much higher core. When you get into a game that is less demanding and the card starts using it's max boost possible you'll likely see artifacts/crashing. Sounds like you are experiencing the same thing as our cards, but just need to test with more than 1 program.

I can also run 1202 core all day long (throttles to 1150ish) on Heaven/Valley, but as soon as I start branching out to less demanding games that won't throttle the card I run into issues. Basically, the card is capable of running 1150-1178 core speed, but in order to get that speed in a demanding game you need to set the max boost to 1200-1225. So, we can't win because that will be unstable on every card due to the watt draw. We have to get our max boost to about 1163-1178 and then deal with the throttling to 1083-1132 in most games.

Enable K-Boost and restart and the card will run your Max Boost on the desktop, then you can see it throttle when you start heaven/valley. tongue.gif

I tried Precision X earlier, same results. frown.gif

So with the following settings and over 1 hour and 15min of Unigine running non stop, here are my results with my card (focusing on the core speed only)

TDP Set to 106 with it Prioritized
Temp Set to 85C (not linked)
Core Offset at +150Mhz
Memory Set at Default
Fan Set to 1:1 Temp:Fan Speed

GPU Power Maxed at: 99%
Mhz @ 1150 Stable and Locked, No Downclocking (Not Using K-Boost)
Max Temp 71C
Max Fan Speed 71%
Max Volts 1.187
GPU Usage 99%

Unigine Heaven Benchmark 4.0 Score of 1623, FPS 64.4 running at 1080p highest settings. CPU 3930k at base clock (No OC).

As mentioned, there was not one drop in Mhz Speed...The Graph is a complete flatline on the Mhz speed.

No onto adding some memory.

Interesting...I have seen it hit 1202 before and it basically almost instant crashed, but is when I set the Offset to +200 on teh Core and had max voltage, Unigine ran for about 20-30seconds before it crashed. Reducing in increments of 20 on the core to 180 netted like 1184 or so on the core, was able to get about a full run before a crash. Reducing to 160 on the core gave me about 1164 or so, Unigine lasted a bit longer, about 3-4 runs before crashing.

I never used K-Boost, but will give it a shot to see what happens. Currently testing the same settings but adding +100 to the memory.

Here I was hoping that I was not having an issue, but does yours lock down at the same exact Mhz with no variations? I have made it throttle when I used a higher fan profile and temps were higher and it would drop from 1100 to 940 or so, but ever since it has locked in at 1150.

Anyone interested in the fan speed wattage...yes, like Alatar said I think it's 3-4 extra watts on the Power %. I stepped up the fan speed while at idle, and it appears to increase wattage after 67% fan speed. 30% all the way to 67% is the same. Once you get to 70% and up, it adds to the Power %. So just a tip- anyone interested in keeping the card cool as possible without the extra couple watts that may cause a 13mhz downclock...use 67%, or right around there. Cards may vary, of course.

But to test, just increase a static fan speed in small increments and watch the Power %. Don't forget to make sure the bump you finally get in Power % is when GPU usage is at 0%. Background tasks bump the Power % here and there when you get small usage spikes from background tasks. So...keep upping the fan speed and take note of what it's at when there's a 0% GPU usage, and when the Power % increases a little when GPU usage is 0%, you've found you're fan speed limit smile.gif


Well, looks like this one doesn't throttle as much, but is still only stable at 1189mhz. Better than the first SC I tested though, so I guess I can't complain. 1189mhz is a +140mhz offset for me (16,121 graphics score redface.gif)-



But with a +150mhz offset, the card got up to 1202mhz, then 1215mhz for a few seconds during most of the 3rd graphics test, but then crashed while loading the 4th test. So...looks like I found this one's limit.
