X800GTO2: Overcloking Temperature

post #1 of 13
Thread Starter 
I've been overcloking my X800GTO2 for a while now and, when it is overclocked, the temperature raises till 104-108 degrees, although the fan spins at 100% speed.

This is why i can't get any higher than a Mem Clock of 573 and a GPU Clock of 442 without having a crash.

So, is it normal that the temperature raises that much?
I have 2 other fans in my computer (12cm of diameter) which I could spin faster. Would this be a good idea?

Thanks

no, thats too high. mine used to top out around 80c (i assume you are talking about celsius). check to see if the heatsink is on properly and everything else is correct with the cooling.

Ehmm, see I'm kind of noob at this, is there any tutorial or, if it is simple can anybody explain me how to do it??

I have to say i didn't change any of the settings on the card (except for pipelines) .. so can it be a fan problem (meaning that they don't cool enough?). And yes, the degrees are in celcius.

Thanks

I would get a zalman (vf 700 cu) to put on it if you have overclocked it,flashed it to X800XL bios then you could oc it to say 530-540 core and 590-600 memory without it crashing.If you haven't already, I would pull off the heatsink and fan and put some new thermal paste on it like artic silver 5.and back off the core a bit as it would be contributing to the high temps.Does'nt take long for dust to accumulate inside the cooling fins too!!!.Do it bi-monthly.With temps at 100 degrees celcius you can turn your thermal paste into crap and it can go off after time and dry out.

Well, the point is, I was thinking about giving my GPU to a friend of mine for his birthday and buy another one (most porbably 1900GT or 1900XT (1950 is too expensive)). I live in france and some cinese sell the Sapphire 1900GT (256Mb) for 190euros (512Mb) and the 1900XT for 290euros.

I don't know. What do you think? Is it better to change the card or to buy a new fan?

The card is a good card to have from what I have read as you can flash it to X850 xt specs and with a good heatsink and fan it can be overclocked to X850xt pe specs which is more than enough for alot of games.It has had 100% success when flashed to 850xt bios.16 pipes working and shazzam.You have turned your mid range card into a high end card like the one you want to get.Buy a new heatsink and fan for it and do flash it then o'c it up.You can't go wrong

Do you mean that I should replace the GPU fan? I took a look at the GTO2 fan and it seems quite built in the card... And also what do you mean by "flashing to X800XL bios: is it telling the mobo the the GPU is a X800XL?

Thanks a lot, and sorry for my ingnorance. ^^


PS: ok, nwm for the X1900s then

Get a Zalman Vf700cu it fits all X800 series cards and comes with instructions on how to do it.Even comes with ram heatsinks which stick on the chips.When you flash a card it overwrites the cards basic operating instructions or rules to the X850 xt's basic instructions if you get my drift?.Go to tech powerup and download the bios.Also comes with instructions on how it is done.You should give it a try seriously,or get a friend to help you if you arn't sure what you are doing.

To remove your original heatsink look for the white circles on opposite corners of the heatsink.These are little pins which spread out the wedged pins that protrude through to the back of the card.Remove the two or more white circular pins from the front side of the card with tweezers and then turn over the card and squeeze the black pins and push them through to the front at the same time.then disconnect the fan plug.then twist the whole thing clockwise and pull up and it will all come off exposing the core chip.Got all that?

Allright, I think I got it, anyway I found several sites with tutos on heatsink removal. Point is that the Zalman Vf700cu is kind of big, i found this photo:

So, I wasn't really sure that it was going to fit in my case... so I got some photos of it too:


What do you think? If it fits (and if it works ) it would be a wonderful solution.

Also for the X850 bios I'll figure that out. And for the Zalman, it has dynamic fan speed doesn't it? Thanks
