What are the odds of hitting 320 FSB on an i875 chipset?

AudiMan · Dec 8, 2003

Providing the CPU can handle it, and I run my RAM @ 3:2?

(On a P4C800, or IC-7 - I have both)

Unlikely though. You need to be really lucky.

Or get an ES so you can turn the mult. way down.

I saw that picture before. It's really amazing what some people are capable of doing,,,

I'm really doubtful that 320FSB is possible with all "things" enabled...
I've been playing the hole day with a P4 that'll Prime at 305+FSB singlechannel, but above 295FSB dual channel 3:2 the board starts to act really strange. The memory can handle 220MHz 2-5-2-2, but at 300FSB, 3:2 I have to lower the memory to 2.5-6-3-3 to get stable operation. At 305FSB I've got such strange problems I can't explain them... ex. going to 640x480 screen res 16 colors for no reson, button missing in programs, mouse acting strange...

Maybe extreme chipset cooling could help...

Last weekend we hit 300 FSB with a 2.4C on a P4C800 with the RAM at 5:4, 2-2-2-6, prime stable for about two hours. Then we started benchmarking, and I regained my first place title in 3DMark with my Radeon 7500.

nice, how much voltage to the Mushkins @ 300?

Grandpa Dan · Dec 29, 2003

Mine take 3.15 above 295

AudiMan · Dec 29, 2003

I was running 3.1 I think. I didn't try anything lower tho.
