I think when Swiftech comes out with this H220x they might work with a full block since the pump and res are integrated into the block. I'll have to get someone to proxy one to me in the US unless they are able to let Coolermaster sell it as a rebranded product.

WOW! Swiftech might have just about everything I need. I'm looking into getting this MCR-X20 Drive Rev3 Series Heat Exchangers with Integrated Pump and Reservoir.

I already know what waterblocks I want: https://www.swiftech.com/KOMODO-NV-GTXTITAN.aspx?variation=469
I just don't know which of these in the instructions for the waterblock apply to a 780 Ti: Warning: Spoiler! (Click to show)

Also, I got a Gigabyte ga-z87x-oc MOBO and I'm using the 1st and 3rd PCIE slot and I don't know what length of fittings I need between the two waterblocks once they're installed: https://www.swiftech.com/connectors.aspx
I'm assuming I should get the 41-65mm ones.

Furthermore, the MCR-X20 requires an external reservoir in the inverted horizontal position (which is how I'd like to put it): Warning: Spoiler! (Click to show)
But I have no idea how to hook up an external reservoir so that the whole things works together.

Additionally, if I have a radiator sandwiched between two fans that are blowing at each other, will that increase cooling efficiency, or is it most advisable to have a "push-pull" configuration?


I know I need tubing, but I don't know what diameter. I'm also not sure if I need any clamps, barb fittings, etc.


Mind helping me complete my shopping cart as well answer some of the above questions?

Best run with the volt modded card running 1.267 volts with the solid resistor mod of 150 ohm on one card. Clocks were 1385 core and 8000 mem


Best run I could do with 1.21 volts with before mod. Clocks were 1320 core and 7900 mem


Pretty good increase in fps and core clock.

Hi guys, my 780ti dual classy is on it's way.It's been a long while since I owned a Nvidia gpu so I wanted to ask a couple of questions.
Is it a locked card in any way(voltage,core clock,etc)?
Can it run on a samsung s23a950d 120hz monitor?The monitor isn't Nvidia certified.
Thanks:)

I can at least answer the Monitor question smile.gif
Since it isn't Nvidia certified, you can not use Nvidia 3D vision. But the screen will function perfectly and can be used as a 120Hz monitor smile.gif

hi guys, just bought myself a palit gtx 780 ti, and flashed the bios. everything worka great but i have a problem.

is it possible to undervolt the card? im getting constant 1.212v, even after i set it at precision x (to 1.137) hit apply. it does not seem to undervolt.

i need to undervolt due to heat issues, running quite hot, 80-83. clocks at 1269mhz/7800mhz.

i reinstall precision, did all the drivers, still the same. whenever i play any game, it will show 1.200V constant. frown.gif

Since it is under Greenlight, the Classified has to follow Nvidia's guidelines of staying under stock volts.
However, with the proper flashed bios, this can be unlocked.

Hey guys

Quick question about this 4 day old ASUS GeForce GTX 780 Ti DirectCU II OC.

I did a quick search through this tread about coil whine.
From what I understand its a normal thing lately with higher end card to have some whine.

Now the Asus gets a slight chirp nothing I can hear unless I stick my head in the case.
Other than the menus on Kingdoms of Amalur Reckoning, then you can hear it slightly.

It was shocking on the 2 Gigabyte GTX780ti's I had previously, my son heard it in another room (They both had the VRAM fault)

I've read a few things but nothing definitive about coil whine, some say it settles down after a few weeks, some say its bad and a fault, or a combination of power supplies etc
Just not clear on what other have come across.

Anyone else getting any form of whine/chip at all?

Just for info I have a Silencer MkIII 1200w Platinum Power supply
