If you really want to push your 770s to the limits then ditch the air cooling and switch to hybrid cooling instead.


Using the stock BIOS and almost no changes to the voltage I had no problem hitting 1302 mhz with my 4GB MSI GTX 770 Gaming cards. And even at that speed I never broke 50C temps with the NZXT G10 and Kraken X41 coolers attached. It ran rock solid stable with the stock BIOS and a tiny bump to the voltage.

Unfortunately EVGA used a custom PCB when they made my 4GB version of my 770 SuperClocked cards. And.. because of it, no one ever made a water block for it in history. No one anywhere. Else I would of been onto a full-cover custom water block a long long time ago. frown.gif

What would adding a water block do? I'm not reaching a thermal limit, the max temperature I've seen is 80c. This wouldn't allow me to achieve any higher oc

It's not about thermal limits, It's about electrical leakage. Components will overclock further if they run cooler. It's basic physics. It's also why all of the world record gpu overclocks are using Liquid Nitrogen.

That may be but how could you be sure having a lower temp would result in a higher oc? The card I have may just not be able to go higher without more voltage. Pretty sure my card wasn't designed to overclock.

Regardless, i don't think anyone bothered making a water block for my card, it's under the "other" on the first post lol

There's of course no gurantee it would yeild anything different from air cooling. But I had a pair of GTX-470 hydro copper cards a few years ago that went to +36% OC over stock clocks on water. And my friend of mine has water cooled GTX 970's from MSI that go to 1650 mhz without artifacts and stable. He was stuck at 1420 mhz with stock cooler on air before switching to water. Would artifact any higher.

You don't need a waterblock for the G10. It's hybrid cooling. An AIO cooler attached to your GPU. The only thing that's required to use one is for the 4 screw holes around the GPU where the heatsink attaches to line up. You will need heat spreaders or heatsinks on your VRAM and VRM, but your card should already have that. At MOST you may need a copper shim if your heat spreader interferes with the AIO seating properly on the GPU, but other than that it should work fine.

Most GTX 770s throttled at 80C. They'll all run up to 80C and then start backing down the GPU speed to maintain that temp.

I've got a comparison for you here. This is my own system with one G10/X41 installed and the other running on air. This is the highest overclock I could achieve with one card running air cooled.

Air cooled = 1246mhz




And this is with both cards liquid cooled =1303mhz




The initial overclock went from 1246 to 1302mhz on the GPU, but even more important since the cards stayed in the mid 40C range there was never any throttling which resulted in a 7fps increase in average frame rates.

You don't need water to remove the throttling, a simple custom bios does that. I have a custom bios from someone on OCN here on my 770 and I can run it up to (and have before) 95c, and 98c on air and it doesn't throttle and keeps pushing my 1202 Mhz overclock with no issues. It removes nvidia boost and all throttling what so ever. My card never throttles, not due to heat, not due to power, nothing. All of it gone, flat 1202 Mhz always at all times no matter how hot or how much power it uses.

Exactly what I want from a video card. I don't care if I have to push it to 100% fan sometimes, or if it runs in to the 90's C, it won't hurt it. Cards are designed to handle up to 100c - 120c before taking physical damage.

And I can't go in to all that AIO water cooler and mounting crap on the ram and all of that mess because my card's still under warranty until 2018 from EVGA. At most I could do a full waterblock then keep the factory air cooler for later. But nothing that does serious modifications to the hardware that can't be reverted.

You've already ruined your warranty by applying a non-EVGA BIOS. And good luck removing that custom BIOS if the card fails.

And FYI, adding an AIO to your card will NOT effect your warranty.

If you have a heat spreader already on the card then you don't need to worry about adding heatsinks. Just swap the GPU heatsink for the AIO and mounting bracket. That's it.

Sorry but that's incorrect. Only single-bios EVGA cards are voided by custom bios's, dual-bios cards are not. I specifically cleared this with an EVGA rep before doing it. I haven't violated my warranty.

http://www.evga.com/support/warranty/graphics-cards/

It's right there in black and white under "Product condition:"

"Unauthorized changes to the BIOS or Firmware on graphics card that do not have a Multiple BIOS option may cause this warranty to be null and void."

And this is exactly why I bought a dual-bios video card from EVGA.
