TITAN + EK XXL waterblock: +200 core, + 500 mem. Temp. 40C.

Benchmark score: 8.13 Ms

A few days ago news of the new GTX780 due at the end of May leaked out and it is to be based on Tesla k20 like Titan, just a little more cut down. It going to have 5gb vram aka Tesla k20c. Should be 85% or so of the speed for about $600 vs $1000. Power required is 225w I think.
People contemplating buying a Titan soon for Octane might want to wait a little longer to get a better deal.
The 770/4gb will be virtually the same as a 680/4gb but for maybe 20% less money too.

Whouah !, great beast ! the EK XXL is great ! Temp is great !
Espescially for octane, Titan overclocks very well !!
My 3 Titan (Asus, Gigabyte and Gainward) are all up at +690 on mem. the offset core are different as I all set them boost max at 1293MHz stable. for this frequency the gigabyte and gainward take +300 on core and the asus take +330.
My 3 EK WB wait for mounting. but not enough time to build.

Titan + 2x580 : 16.55 Ms/s
2 x Titan : 17.16 Ms/s

itou31,

On my OC settings gpu power (MSI Afterburner indicator) reaches 80% while Octane is running. There seems to be spare power at least 20%.
When I use kombustor to test gpu, power and heat drastically increase. What is this 80% usage ny octane? What kind of resources Octane don't use (this 20%)?

Did you find any info what is safe overclock for titans? Your +700 on mem. seems high - is it safe? What would be a result of exceeding +mem overclock? Would it be burnt or just it would stop working?

Hi smicha,

I use EVGA Precision X 4.1 to overclock all Nvidia. and also use GPU Meter gadget (+PC meter) to monitor the GPU load.
Octane take 99% GPU Load. And on power it reach 90%. I have flashed a modded bios to prevent the titan to throttle when I play with fans and offset memory. I have note that even all my titan have the same bios, they have not equal boost.
Yes, the mem offset and core is a bit high, but this setting is for octane. With games, you can't go to these number.
For memory, go by +20 at each step. When you go to high on mem, it freeze, or getting some square on screen, then go back -20 or -30, and then it will be OK.
I think that I can get further when I put them on water. I think that the backplate is goot for memories chip on the backside.
All my 3 Titan go up to +690 (on air, but only when high fans and temps are <65°C). Some tested with +750, but failed when T° goes over 60°C.
Also tested with octane 1.13 with scene with 3GB VRAM.

itou,
Thanks for sharing the information. Please post results for your titans when you get you waterblocks.

how is the gtx590 now compared to Titan?

A small diversion for hardware hackers I came across today
http://www.eevblog.com/forum/projects/h ... nterparts/
Not sure this is very useful for Octane users but I thought to drop it in here for interest.
I see also the GTX780 is now rumoured to cost quite a bit more than a 680 - nearer a Titan @$700-750 - so maybe no free lunch there....

Hi
Have take some moment to mount these titan :




the 3 titan have these settings :
1 : 1345 Mhz core and 3780MHz memory
2 : 1319 MHz core and 3720MHz memory
3 : 1332 MHz core and 3740MHz memory

PT : 26.40 Ms/s

looks sweet!

Is the PSU for the whole system or just for the cards?
Regarding that, would that even be possible? Just slap in another PSU for the 6pin/8pin of the cards?
