50 MHz FSB

[cooler]

I have a Gigabyte-6VA mainboard. According to the manual there are three settings selectable by jumper: auto, 66 MHz and 100 MHz. Currently 100 MHz are selected. However, several tools/benchmarks show that the FSB is only running at 50 MHz. I tried to increase the speed with CPUCool but the PC already locks at 55 MHz. Is there a bug in the tools or is my PC really running that slow? If so what can I do?

Have you tried CPU ID? It gives alot of info

Has the CPU multiplier been changed ? If it has then it may not be able to take both an increase in Multiplier and Bus Speed, as this will result in a large Overclock.

I think it's a bug in the tools. Update them.

Cooler,

My CPUcool (version 7.0.14) has Gigabyte boards listed, but not the 6-VA. It may be just that simple. I've noticed that if I have the board & chip 'correct' I still need the right PLL also for it to work. It seems to be *very* specific in its application.

D8's program: http://tweakdb.tk , CPUID, MBM [Mother Board Monitor] & 'Fresh Diagnose' [all @ www.guru3d.com I believe) *might* give you some system info that may help. I don't know if there is a newer version of CPUCool (than I have) that has that board, but these other programs are nice to have anyway. :grinthumb

HTH,

Try setting the Jumpers to a different speed. I had this problem on a couple of old boards, the labelling (even on the PCB) is wrong, in the easiest case, all of the jumper settings were reversed, but the other board took trial and error.

BTW, thanx for plugging my program

New version out soon

Isn't it that CPU uses both rising and falling edge of the clock signal, so that a 50 Mhz clock signal makes the CPU run at 100 Mhz *multiplier?

AFAIK that only applies to DDR chips (i.e. Athlons with 266 Bus)
