Hello 
 
just installed the HydroCopper from EVGA, and the GPU does not seem to be stable like it was before
 
With the HYBRID solution, I was able to OC the Memory +900 (Samsung chips) and +100 on GPU, temps were 60 under load and 50 on memory
 
Now with the HC, I can't get it past 600 on memory that it crashes/freeze/artifacts, it seems stable on GPU. Temps under load never go past 50 and 43 on memory.
 
At first I thought it was the riser extension cable (Phanteks premium), after installing it straight on the mobo nothing has changed.
 
Also I took it apart thinking that maybe there was too much thermal paste, reapplied and put it back together but same issue.
 
Any ideas?
 
I've even tried Afterburner, but same thing.
Tried different drivers as well.
 
Here some pics of the artifacts

thank you

What kind of TIM did you apply?

Do the artifacts go away if you put the stock cooler back on?

Went back to stock Hybrid cooler and have been running Superposition Bench just fine +900 on memory (temp 58) and +90 on Core (temp 57)

What kind of TIM did you apply?

Is it possible that the metal stand offs on the HC are creating an electric static to the main board?

Could have been something silly go on. 
 
Make sure the dark side of the square GPU bracket used when installing the HC was facing down so it's grounded.

Yes it's facing down, I've seen other posts mentioning this and followed the instructions
 
It seems very silly, it doesn't really make any sense though
 
The thermal pads are not super squished, I can see the shape of memory chips and power modules
 
I'm even thinking that maybe there is something in the loop conducting electricity and make the GPU stops.
 
Don't really know what to think of anymore

The memory temperature was supposedly significantly cooler with the Hydrocopper versus the Hybrid. That can make a difference. Memory doesn't necessarily behave the same at different temperatures.

On the other hand, the memory was only "supposedly cooler" but there is no way of really knowing that it was cooler without laying a thermocouple on top of or against the side of the memory chips. The reported "supposed" memory temperature is heavily affected by the PCB temperature and therefore if the hydrocopper block keeps the PCB significantly cooler, the memory could be actually hotter but reported as cooler.

Some food for thought.
 
I would guess that the difference in memory performance is related to the difference in memory temperature; whether hotter or cooler.  I mean... I guess the difference could be due to a difference in electrical interference and inductance in the memory trace loops, but I doubt it.

The Black side faces the PCB.
Aligned but not laying on top of any components.

I think removing the GPU bracket folks have to be careful they don't damage or crush the die but maybe the screws are spec'd so that won't happen.
 
Nonetheless, glad it all works out for you so far OP.

AHowes
Nuts.. so no GPU bracket equally better contact to the memory chips or GPU?

Man what is up with the company making these blocks. The height tolerances need to be looked at.

Guessing the standoffs all too long and when removing the GPU bracket it allowed the pcb to flex and make better contact.

Yeah it seems the tolerances are a bit odd
EVGA with this series already made me unhappy with the pump whine on the hybrid kit
Let’s hope they can fix it

Ok so here is a new update on my current situation
Since the new manual is not available yet, and I couldn't wait for it, I gave it another try and installed once again the gpu bracket, as I did at the very beginning.
 
And guess what?....now it's working fine!
Not sure what has changed, beside the fact that I tighten the bracket screws a bit more and the black adhesive was not perfectly centered (I took it off and reapplied aligned to the bracket)
Everything was sitting properly and at his point I still don't know what was going on.
 
Latest Driver and Latest Precision X1
I'm running Superposition 1080p Extreme and the Score is 7514
Room Temp is around 20
GPU 1 46 and GPU 2 41
Memory and power never goes above 40
 
I hope I can finally enjoy my fist custom loop without having to go through this kind of issue once again.

Cool GTX
good news
 
I was just going to mention - check the screw length of the GPU bracket - if they are a tad long it could cause issues
 
Maybe water block was not sitting perfectly Flat on the GPU the first time ?

I tried so many times that I'm not sure if it was the block not sitting straight or the black adhesive being a bit off center or the screws not tight enough 
 
The screws once tight, they were right on the edge of those 4 small standoffs.
 
I now hope for the best, and that EVGA makes a much better manual for the new people that are going to buy this Block.
 
Here is an image of my first loop, hopefully one day I'll be able to make something more sexy Lol

Nice~!

Thank you
 
I had to change it a bit along the way, I'll buy some more fittings to get it as I wanted it to be

Rock it out!

Congrats on your working card. 

here is an update on my current situation
 
I didn't really have much time to test the card with the new block once I've installed it, but in the past few days I had the chance to put some load on it.
 
After +/- 30 mins of gaming, with just a little OC on memory +600 and +75 on core, the card started freezing with artifacts once again.
 
So I decided to remove the bracket one more time and test again, and the issues are gone!!!!
 
 
EVGA support said that they were going to revise the instructions on May 3rd, as of today nothing has change on the manuals available online.
 
The bracket was delivered with the black adhesive on the opposite side of the standoffs, and I've installed it with the black part facing the PCB, and I noticed once again when taking the block apart that the paste was not spread out even and since the card is vertical was kind of coming out from the bottom.
 
I do still have doubts about this bracket solution, I hope EVGA fixes it very soon.
