a few 7970 issues..

post #1 of 7
Thread Starter 
im going to try and describe this as best as i can

i have a watercooled 7970 with a full copper block from dangerden
from the beginning i had abnormally high stress temps (gpu was hitting 80-90+c in furmark under water, and then my pc would shut off, presumably due to the gpu)
i replaced the TIM on the gpu and they dropped considerably, to around 65c under load, and the computer stopped crashing
fast forward 6 months (now)
i never played many graphics intensive games due to time restraints, and now i finally have time, i'm trying to play them
the gpu makes a weird buzzing noise, not whining, but it sounds like something is scraping against something else, and this only happens while in a graphic intense game
it also starts from high to low, pitch wise, on a 1 second beat, it almost sounds like when you stop a spinning cd with your finger, starts high, ends low, but it starts over immediately
on screen the screen lags every 1 second, nothing super major but it is definitely noticeable/choppy and it is perfectly in sync with the 1 second grinding noise..
i ran furmark again and the temps got back up to around 80c and the computer crashed again..
if it's worth anything, the first time i replaced the TIM i took the block off and it almost looked like water had gotten into it, it was really muddy and not much tim was even on the chip, despite me nearly smothering it.

i'm using prolimatech pk-1
is this a graphics card issue? a cooling issue? a block issue? tim issue?
i'll be more than happy to provide any kind of help i can, and if the sound issue makes no sense, i can take a video to try and show it off better.
thanks so much for any help anyone can provide,

tgt

Its most likely coil whine. If the GPU and VRM temps are good then i see no problems.

Is the card OC'ed or stock clocks? what volts are you using? How is your loop set up (a pic would be nice) ?

90c for a WC DD block is not normal, but even then, it shouldn't cause the PC to shut off. You have other problems.

Mine on air can reach up to 98c with no issues except for heat. High temps like that are not recommended, but it still keeps going.
Daily usage in heavy gaming is usually 86c for the top card and 83cc for the bottom one.

The noise you are describing, you are sure its emitting from the 7970? or it might be another component(s).....

As for the TIM, its supposed to feel muddy, unless it has been applied in the dark ages, then it would be rock solid (almost like cement).

Have you done any water-leak testing for the block & the entire loop?

The card shouldn't even be reaching 65c with that block on it. Something tells me there's something wrong with the block, your loop or the way it's mounted.

apologies for the late responses everyone

my loop is as follows
pump>gpu>360mm rad>cpu>pump

and yes i'm quite positive the grinding noise is coming from the gpu, as it only happens when something graphically intensive (game or furmark etc) is on the screen

as for the muddy part, i meant when I took the block off to clean it and apply more TIM, it was milky like water had gotten inside of it, but i'm pretty sure that's just leftover water from when i took the block off and dismounted it

the card is at 100% clocks, and it's being powered by a corsair ax750. i have literally changed absolutely nothing.

i guess i'm going to try it on a stock cooler and if both problems persist, RMA it..

I cant see it be anything else than coilwhine.

I thought coil whine was a high pitched whistling? I've never had a card with coil whine so I legitimately dont know what it sounds like.
/e
and I thought coil whine didn't effect anything performance wise? Like I said the screen lags/jitters perfectly in sync with the noise
