post #6201 of 11726
Hey, been running some tests today, Heaven, furmark, firestrike and it seems to be running fine, alltho is there any program or software that would tell me its not stable?

It seems my VRM starts giving me artifacts around ~74-75C.

I need to test this more, turn my fans around so my rad is blowing air outside and not inside the case and see what happens, hopefully get the temps below 75C at all times, adding 2 extra fans (Missing one fan..) to my Rad for 5 Fans total in Push/Pull dropped my temps in the long run by 5C already, adding a third fan and pushing the air outside should keep it below 74C or so.

This has been my experience as well. I want to try adding a fan directly next to the GPU so that it blows air directly into the heatsink, just in case it improves things ever so slightly. I have my two bottom case fans blowing cold air on it alrady though, so I doubt there's going to be much difference.

My issue with this is that I can't have my fans ramp up and down depending on GPU temps or even depending on whether I'm running a game or not, so I have to do it manually and that plain sucks.

When you say artifacts, I guess they are random flashes of colors, right? That's what I get when temps start being an issue. Else, it's just white or black squares, like checkerboard or something. I also get black screens every now and then when trying to run my memory higher than 1700MHz. God damnit.

It's like a small flicker on a texture somewhere every few minutes, it's nothing major. But it doesn't happen at all until the temps ramp up.
Exactly like the checkerboard you described.

So I'm thinking I need to get them to 70C or less under any case.. I'm hoping reversing my radiator fans will help this out a lot as it isn't blowing the constantly heating up radiator air directly to the GPU anymore thus kinda making the temp rise exponential (GPU heats water and radiator heats the GPU more from the rising water temps).

EDIT: I left Armored Warfare running in hangar when I went to watch deadpool, temps rose to 47C Max on Core and 78C/49C on the VRM.

Less than that 81C I was experiencing before atleast.

I'm trying to get 1200mhz on liquid, but even with all the power + core up, I can't seem to get past 1115mhz on core and 1700mhz on memory.

Add more Voltage.

Card stuck at max clocks at all times all of a sudden? Trying to put less clocks on MSI AB and it reverts back to what it was.

Weird? Any idea why it happens?

EDIT: Well this is weird, I tried to go and change the refresh rate...

Well reboot fixed that but clocks are still stuck at max at all times for some weird reason.

Just bought a digital thermometer to see some temps, ambient is 25.3C and rear exhaust gives me 31.8C. Heating up the room nicely.

I turned the heating off completely in this room, get the ambients down a bit and get that VRM near that 70C or less. And turn the radiator fans to exhaust instead of intake later today.

EDIT: In 10 minutes after turning Armored Warfare off, ambient is now 23.9C and exhaust is 28.1C.
EDIT2: Temps seem to settle at 23.7C / 26.9C now.

woo! new PSU arrived! got myself a evga supernova 850w G2, so i should be installing that tonight, should make my system a bit more stable :-)
(i was trying to get the 750w g2 but amazon has been out of stock of those for weeks and they dropped the price of the 850w over the weekend to a nice round 100quid mark so i went and bought that :-D futureproofing myself i hope, considering this thing has a 10year warranty on it if i can recall correctly)

Yes, 10 year warranty, but you need to register it on evga website to get that.
