Tiny flashing pixels after waterblock install.

post #1 of 10
Thread Starter 
So installed the EK copper block on my GTX570 today. I took it slow, never encountered any issues.

completed the loop, leak tested for a while with the PC off, found once small leak that I am dealing with (not in the box, the leak is in the external rad box).

Temps are great, GPU idles at 29, max load at 39.

went down stairs to put away some tools, came back and sat at the computer and noticed quite a few tiny flashing pixels. Still there after a reboot.

Did I some how manage to screw my card? Anyone seen this before?

it's not there all the time, for instance as I type this in the browser, I can't see any. it's there in games, or say heaven benchmark and there on the windows desktop.

Any ideas?

Are you overclocking at all? Artifacting is typically a symptom of an unstable overclock. Increased voltage might help. With the GPU being water cooled, you should be able to bump the voltage a bit with no serious impacts to temps.

It's a 570 SC card so it's clocked already at 797. I had it at 800 .. anyhow I solved the problem... was a cable.

gave myself a bloody heart attack though.. put it back to 800/2000 and temps are a solid 29 idle, 39 load.

happy happy happy!

This your first time using water? How hard did you find setting it all up?

I took it slow and I am doing something outside the box (literally) so it might not be atypical but if you have read a lot, I found the actual "doing" was easier than I thought it might be after reading.

I am SO impressed with the results too.

I went slow, I double checked things and only really ended up with 1 leak (that i am still trying to decide how to deal with, really dont want to pull this all apart).

idle temps actualy went down, about 8-10C, load temps went down about 25C.

I now idle at 25-28, with a "system temp" of 28. (same as it was pre water cooling). My ambient is about 23-24 or thats what the thermostat is set to in the house, it's usually a degree or 2 higher in this room so lets say ambient is 25.

hour of prime @ 4.5 Ghz - 1.25v on a i5-2500K is 45C. Bumping up to 5.0 Ghz has me sitting about 55-60C

all in all very happy. just need to pwm this pump to quieten it down a bit.

I drove myself bonkers for a week one time when I was getting artifacts on my monitor due to the same issue, slightly loose DVI cable!!!

I played with my overclock settings for hours, stopped gaming for a week so as to not stress the card, only to have a friend suggest I double check my cables...d'oh!

From then on I always screw in my cables to ensure proper contact and prevent those damned artifacts.

OMG.

I had this same problem last week!!! I was playing a game (no artifacts) and alt-ing to my browser while playing and I noticed on a page with a black background that I was getting red dot artifacts all over the the background. I crapped myself thinking my GPU got damaged somehow (even though I've not installed a water block on it) and spent a good 30 minutes trying to work it out and downclocking.

Then it dawned on me to check the DVI cable. It was slightly loose on the monitor.... problem solved!!!

However, after that incident I keep imagining dots on my screen. Bloody annoying.

Reapply the TIM. There is probably a gap.

The temperatures read good because they only monitor the temp at a single point.
Once again...

^ no need, the issue was a cable... but appreicate the reply, that was first on my list.

I am going to be reapplying the TIM here soon anyhow, I used "budget" TIM from tigerdirect/compusa (only local place to get anything reasonable), it was a thermaltake brand. I am going to order some good stuff and redo the CPU and the GPU.
