[QUOTE="Raijinko"]

the default on the gpu was core clock 625Mhz and 993 memory clock out of the box, then i i did auto tune from the CCC the card broght and it raised it to 690MHz core clock and like 1100 somrthing MHz memory clock.. then i get black screens and bad image when i play Cod4,so it freezes. and why is the memory clock so low if its advertised at 1986 MHz.

Maybe you are going too far with it.

ddr= double data rate.

1986= 993Mhz on your CCC you got to times those by 2. so 1100 is 2200Mhz

I bought a HIS ATI 4850, I read that u needs a 450W psu or higher, so i bought a 450w antec, I played CoD4 perfect in max settings with the gpu in default, but when i increase fan speed and core clock and memory i get a black screen or the monitor starts displaying retarded images. is it the psu that cant handle it or is the gpu messed up? the default on the gpu was core clock 625Mhz and 993 memory clock out of the box, then i i did auto tune from the CCC the card broght and it raised it to 690MHz core clock and like 1100 somrthing MHz memory clock.. then i get black screens and bad image when i play Cod4,so it freezes. is it my psu fault? and why is the memory clock so low if its advertised at 1986 MHz. Default was decent cause it was playing CoD 4 max settings 50-120fps, but in crysis it was in the 20-30s in high, i want this to do what it says. also my psu has almost no load, i only have 1 dvd drive, 1, HDD, and thats it.

I was thinking of upgrading the processor on my Dell E521 from a amd Athlon 64 x2 3800+ 2.0 ghz to a 5600+ 2.9 ghz, and came to realize that amd no longer sells the 90nm chip of the 5600+. Would using the 65nm brisbane model instead of the 90nm chip work on my computer or should i try and find a 90nm chip?

The 4850 runs pretty hot. Did you set the fan or did you leave it on auto? For me my 4850s idle at around 54-56C at 50% and as far as I know most of them with stock coolers are pretty hot.teh_VU

Well , your CPU temps of 30-35C are just fine. With CPU's once you start getting into the 60C mark is when your getting too hot. A very good Temp program is CoreTemp.

GPU's are good till about the 80C mark but just sitting idle at 60C is a bit hot.
