Hi all
I have just upgraded my gfx card on my old AGP based system and to try to take best advantage of this card I am in the process of overclocking my system, since it is holding the new card back.
Old gfx card X1950Pro, new Gfx card HD4670.
Asus A8V, AMD X2 3800+, 2 gigs (4x512MBs) budget PC3200 RAM.
I have raised the FSB to 266MHz, but have had to reduce the HyperTransport to x3 (798MHz) (x4 won't boot) with an increase in the CPU voltage of 1.35v -> 1.5v.
My problem is with my RAM, since its budget its basically will not OC. The only memory divider that I can get it to boot on is 1:1 which CPU-Z reports as running at 133MHz. But to max my performance I want to get the memory at as close to 200MHz as i can.
The memory dividers available in the BIOS are 1:1, 4:3, 3:2, 5:3, 2:1 which based on a FSB of 266MHz should result in the memory running at 133, 177.3, 199.5, 221.6, 266. Therefore I would assume that I could use the 3:2 divider but as mentioned above only the 1:1 divider will allow me to boot.
I'm an OC'ing novice so any advice as to how I can get my memory running at a faster speed would be very much appreciated.
Thanks
