In the BIOS, I have followed numerous guides and simply cannot get my computer to boot past an FSB of a fairly lowly 270. My setting are:
Robust Graphics: Auto
Clock Ratio: x9
CPU Host Clock Control: Enabled
CPU Host Freq: 270
PCI-E freq: 100
System Memory Multipler 2.00
Memory setting 5-5-5-15
Everything else on Auto
DDR2 is at +0.2
FSH overvoltage: normal
CPU Voltage 1.35v
I have also disabled C1E, EIST.
So - I'm clearly not stressing my ram which can I've tested and can run quite comfortably at 5-5-5-15 at DDR2-900 speeds.
If I go one FSB above 270, my system won't boot. I have tried raising the volts up even gradually to 1.45 with no luck. I have also done minor raises to the other voltage settings with no difference.
I tried lowering the multiplier to 8x but the FSB wouldn't go abot 270. I've tried going to much higher levels as well like 300 but this doesn't work.
Hi there - thanks for your replies. Unfortunately, the x2 multiplier is the lowest multipler on the gigabyte - it takes into account the DDR2 multiplication. So 270 FSB is actually rated by the motherboard (and on cpu-id) as DDR2- 540 on a x2 multiplier. To demonstrate, I've currently got the multipler at x3.33 on 270 FSB which is giving me a ram speed of nearly 900 and it's comfortable at these speeds.
What I want to do is obviously increase the fsb (at which point I'll lower the multiplier). I just keep running into the problems listed above.
