I realized I have these problems becouse the card's are quite different and becouse of the memory
I flashed both card's bios to the same clock speed's and now it' working allitle better
Wich card should I put in the first PCI-E slot, the 1GB one ore the 512MB?
I have a ASUS P5N-T DELUXE Motherboard
Is there any way I can flash the 1GB card to a 512MB card ? becouse that coolbits value 18 I don't think it's working properly
