I did some testing in 3DMark11 and it takes 4.8ghz to fully use all 3 Titans. You should easily be able to handle 2 Titans with 4.2ghz.

It doesn't work that way. There is no magic number that it takes to power 3 titans. I've had my 3930K up to 5ghz and still was unable to get all 3 Titans @ 99% GPU usage @ 2560 EXCEPT in Crysis 3.

Crysis 3 is the ONLY game that will push 3 Titans the way they're meant to be pushed. Otherwise 2 Titans OC'd is the perfect setup for 2560x1440/1600, hands down.

BF3 does NOT need more than even 1 Titan at 2560x1440 maxed out with my CPU at my daily OC which is 4900mhz on my 3930K. With 2 Titans, I'm usually hovering around 120fps in the open maps, and bouncing off of the 200fps limiter in the closed maps in some areas.

how about the thermal pads, are there much better pads available than what I have now? backplate and titan are both EVGA.

as an aside, does anyone know if all Titans have the same TIM? or, to put another way, who mounts the heatsinks, nvidia or EVGA/Asus/etc..?


I am about to order a high flow bracket and the best recommended TIM.

thank you

You have to edit that bios. If I'm not mistaken, the gpu boost table is kinda high in Wolferins bios. Just lower it and you'll boost less. wink.gif

would two titans be ok with an i5 3570k @ 5ghz? or should I wait for haswell

Haswell, from preliminary reports, will be 5-10% faster than IB with with OC capabilities yet to be known. Your current CPU is way more than you need gaming wise. If your wallet is really burning a hole in your pocket, wait for IB-E.

Are you increasing the voltage with the slider? That puts the boost clock into overdrive, either have to not increase voltage using the slider or edit the boost clock down.
Might not hurt to try the cards independently, see if one is less than great & dragging the other one down.

Replacing the TIM can help, there are premium thermal pads out there for better thermal transfer but I haven't used them yet to see if there is any difference, I don't normally bother replacing pads until the current ones get dirty or ripped.
Better TIM & application does make some difference, replacing pads would likely make little if any difference.

I have trouble with OC crashes in Skyrim as well. Seems to be very finicky with an OC.

Are you guys talking about Skyrim with ENB or vanilla Skyrim?
My oc went through several hours of Far Cry 3, BioShock Infinite, Crysis1 & 3 torture without crashing. so I thought my oc was stable for 24/7..... until today. My Titans crashed in GTA4 with ENB. :-(

I did already. One card is 66% ASIC and is a pure crap clocker (its the reason I can't go over 1163MHz). The other is 73% I believe and it will do 1202MHz... rolleyes.gif

But that's in 3d mark, those tests are designed to stress the gpus not the CPU (talking about just grfx tests). In battlefield 3 a large chunk of that CPU power will be used up by the game so your conclusion pointless when it comes to gaming.
All you have done is worked out that there is no CPU bottleneck in the 3dmark grfx tests. Of course theres not or how else could it properly test the gpu if every man and his dog was getting a CPU bottle neck?
You're seeing those gains up to 4.8ghz because 3 titans really is pushing that 3770k.
