problem with x1950pro

[doran1801]

i have just water cooler my pc including the gpu, howver when i try to play company of heroes or try to benchmark using 3dmark 03 the monitor goes into standby and the only way to fix it is to reboot. this did not happen when it was on air . does anyone know what is going on?

anyone?

tried that, the temps of the gpu are steady at around 30c.

going to try the air cooler tonight. The psu is the mae as before so i do not think it is a power issue. on the cpu cooler, it came with a 3 pin connector for an led which takes the place of the fan, i wonder if the same should not be on the gpu

soething to add to this is that my mobo bios resets when this happens and i have to set the time and boot sequence again

can anyone shed some light on this before i start to strip pc down again?

the vrm's need cooling aswell check this thread on the sapphire forums

you're a star!
thanks for that, it turned out that it is an underlying problem with these cards and a really common problem. when i put it under water, what little airflow the vrms had went causing the problem, for now i have put the stock back on with some more compound on the vrms and it has worked fine

does anyone know where to get some aftermarket vrm coolers for for this card? I have an unused vga water block i cannot use until i can get hold of the heatsinks. Also i have some vga ram sinks here, will they work? they are bigger though and i am worried they might short something out by conecting the vrm to something else

 

[doran1801]

i know you are watercooling but any chance you canget a low rpm 120mm fan near the gfx for airflow that would be silent? but if your case has windows then it will look crap though lol

that is my last resort. but i would much prefer to sort the card out 1st

 

[doran1801]

are the vga ram sinks that much to big ???? can you hacksaw em down to size ?? bit bodgy but they only cheap and could be worth a go

can't find my hacksaw, think i left it in prison!!
seriously though, that seems like a good idea but would it not warp the surface of it? if not i will do it tomorrow

 

[doran1801]

i guess its possibl. start the cut from the bottom though. it could be fiddley but i dont know what the sinks are made of if aluminium should be easish to cut. if you arnt using them and they are laying around maybe worth just trying one see how it turns out. how do vga ram sinks attach they stick on ?? or you use thermal paste ?

they have sticky pads on them

 

[doran1801]

well, tonight i tried to use the cut down ram sinks on the vrms and they got hot abd shut off the card witing 30 secs of 3dmark05 so it is safe to say they do not work!
i have heard that there is another version of this same card, like a revision update and it has a zalman cooler and a massive heatsink right over the vrms, does anyone know where to buy one of these separatly?

 

[doran1801]

as soon as i put the stock back on it works like a dream, it just a shame i cannot put it under water, the idle temp at stock are 45-50c but under water it was only 25c . the vrms must be running pretty close to the edge constantly for this to happen
