FSB:DRAM problem

[twitch]

Hello,

Now I have been trying to sort out why I can't seem to go above 400FSB..

And I have come across a strange thing..

All voltages at auto

If I set the CPU to 375*8 so its @ 3000 Mhz and leave the FSB : DRAM setting to auto (5:8) Ram running at 601 (1202) it's fine have had it running for hours with Prime95 running tried all sorts of games and not a single crash, max temp 61.

But if I manualy set the FSB : DRAM setting to 2:3 which makes the ram at 562 which is closer to what it's ment to be 533 (1066) Nothing no boot up can't even get in to the bios settings...

Have tried all sorts, diferent timings, voltages.

So could this be a flaw in the bios or motherboard ??

Thoughts ??

Thanks

Which motherboard?

If you're talking about the rig in your sig then having the memory running at 601mhz is closer to its stock speed than 562mhz is. The stock speed of PC3-1066 is 667mhz (1333mhz).
