497137 2006-11-07 05:18:00 I have an MSI P4MAM-V motherboard with a P4 3.06 Ghz chip mounted and the latest BIOS flashed but for some reason the chip is only running at half the speed. I have checked most things accessable in the BIOS setup but some are still "greyed out" therefore I can not access them. I am reasonably "computer literate" but this has me bugged. Can anyone offer any advice to get the chip up to speed? Davier (11406)
497138 2006-11-07 05:21:00 How much ram is on the mobo and what version of Windows is installed? Speedy Gonzales (78)
497139 2006-11-07 05:24:00 There is 512Mb of RAM and I'm running Win2K Davier (11406)
497140 2006-11-07 05:25:00 what FSB is it set to?

have you got varible speed enabled?

are you sure that mobo supports that cpu?

497141 2006-11-07 05:27:00 The mobo definitely supports the chip as it was running at the right speed in a previous build. Unfortunately when I flashed new BIOS, the previous settings were lost and now I'm where I am.

FSB seems to be OK being checked with CPU-Z

Variable speed enabled??? Help me here.

497142 2006-11-07 05:33:00 check fsb settings (should be 133 or 533). check memory settings, it may have defaulted to scynous (ram the same as fsb) and set the fsb to the speed of your ram (eg slower).

some mobo's have speed control to slow it down to save power and/or overheat protection.

497143 2006-11-07 05:37:00 It looks like its a 400/533 fsb mobo.

Is the CPU 533 fsb?? Its not 800 fsb is it?

As I dont think this mobo supports 800 fsb CPU's.

And it looks like it only supports 200/266 mhz ram. Which isnt that fast.

When u flash a BIOS, its usually a good idea to set the BIOS settings to the default settings, and reconfigure them, then save the BIOS settings.

497144 2006-11-07 05:39:00 Rebooting and into BIOS, the FSB says 100Mhz, Dram 133Mhz and DDR 266Mhz. All greyed out so I can't change them. Yet CPU-z sais FSB was 400Mhz????

Any thoughts?

497145 2006-11-07 05:42:00 Thanks Speedy, I am using DDR400, would that screw things up??? I know that previously there was DDR266 installed and it worked AOK Davier (11406)

Any thoughts?
thats your problem, fsb should be 133 . cpu-z said it was 400 which is correct . p4's run a quad bus eg 4x100=400 .

you need to change it to 133 . how? no idea without downloading manuals etc, youll just have to use your eyes and fingers ;)
