Overclock Unstable After Switching to Water Loop.

My set up -

Mobo - Z170-A Pro
CPU - 7600k OC @4.6
GPU - Asus Strix 1080ti
32gb ddr4 gskill


Issue - unstable GPU overclock after installing water cooling loops

- I had a stable overclock on the GPU prior to watercooling. Never had an issue for weeks. I had the core clock at 2050mhz (or +70 in Asus GPU tweak terms). Memory clock was maxed and stable in GPU tweak and I had the power limit all the way up to 120%. I left the voltage alone. However with this overclock I was getting temps reaching 82c since my case is no exactly air flow friendly. Fans were on 100% and it is quite loud. I decided to go to water cooling, something I have wanted to do for a long time. However, since watercooling, my gpu overclock is unstable. My temps are down by 25-30c, now in game (usually 20 minutes before I get display driver error) I run around 53c max. My CPU almost never goes about 50c which is extremely awesome in my opinion, might push that overclock a littttle more too. However, I'm still dumbfounded. Why would switching to water make my OC unstable even though its cooler? Any advice is appreciated.


Custom water loop info-

Pump/res- xspc x4 photon 170.

Radiator - xspc EX 360 (mounted outside of my case on its own little circuit)

CPU block - XSPC Raystorm V3

Gpu block - Bitspower Clear Acrylic


Thanks

  1. Is the GPU stable at stock settings?

    If you haven't tried, set it to stock settings then run a furmark test and see if it behaves.

    Also, what PSU are you using? You've potentially got a larger power draw now after switching to a water loop and if your PSU isn't up to spec, then it could cause this

    Logically, yes you would expect the same OC to remain stable with a better cooling system, but OC stability can be influenced by the slightest environmental changes.

    There's also the possibility that in fitting a waterblock to your GPU, you might have accidentally damaged the GPU in some way.

  2. I have a corsair 600 watt. I THINK I'm solid on power draw with that. Also, it seems to work fine if I bench and play with stock settings and even lowering my OC a little.

  3. I also don't think that I have damaged the GPU, I know it's possible, but I was insanely careful with everything. My 1080 ti is my baby lol.

  4. In that case probs best to just play with a slightly lower OC

    I had a similar but opposite issue with a CPU OC

    Unplugged the PSU to move things round a bit, re-connected everything and hey presto... my cpu could now reach an OC that it previously failed when benching

  5. Interesting. Well thanks for the input, I may get a new PSU too and test it out. The gtx 1080 ti recommends a 600-650 psu so I'm at the low end. That's not including a water loop and OC so maybe I am running a bit short on juice as well. Thanks for your input

    If you have a Corsair 600, you're probably due for a quality upgrade anyway given how much you've invested in your machine - the 600W Corsairs that one's far more likely to encounter are the VS and the old version CX, neither of which are that good.

  7. What would you recommend for a PSU? I have the CX600 modular version right now.

    Now, PSU issues are more frequently power-off situations than instability -- though it can happen -- but with a $600 GPU in there, it's a good opportunity to get a PSU that isn't meant more for office builds and simultaneously eliminate a possible problem.

  9. I mine as well get the 750 off Amazon for $5 more then.

  10. Scratch that, the G3 is $120 for an 850 watt. I'll buy that one

    Hey Zachary_49!

    I dont know the Bitspower clear acrylic so i am just wild guessing and guess that this Waterblock is not covering the VRM's and/or other important components?
    Try putting one or more fans in the case blowing directly at the video card at full speed just to test IF then the overclock is stable...

  12. The bitspower does cover everything, it is a full block, and had excellent reviews. I also do have an intake fan blowing directly through the GPU area as well
    Reply to Zachary_49
  13. I was also going to say, double check that the VRMs have good contact to the cooler. You installed it yourself? Did you use thermal pads or paste or what? Did you check that they were contacting/smearing before final install?

    Otherwise, could definitely be PSU related.

  14. I used thermal pads on all the VRM. They are plenty snug and touching

  15. I also bought the EVGA Supernova 850?but it was DOA, so waiting for replacement

    After putting in the new processor, I am happy to announce I have a stable overclock at 2.1ghz on my 1080ti. Also have my OC on my 6700k @4.8ghz with an offset mode that reaches a max VCore of 1.387v. Seems to be stable but I'm iffy lol.

  17. Meant power supply not processor
