Travelmate 800 Clock Multiplier

Hi,

I've got a new Pentium M 740 1.7 processor for my Travelmate 800, the slowest of the 800 series with a 1.3 Pentium M as standard. The chipset is good, the screen is good, the graphics card is good, so I've decided to try an upgrade.

My problem is that I haven't been able to work out how to raise the clock multiplier despite a lot of searching on the web. I've pulled the motherboard out and can't find any jumpers on either side, and I can't adjust it through the standard BIOS pages. I've reflashed the BIOS, in case it was some form of autodetect.

There is only one motherboard / part number listed for the 800 range and there is no need to specify processor speed when ordering, so as far as I can see there MUST be a way to change the clock multiplier for the different processors in the range.

Any ideas much appreciated.

Rob.

 

Most CPUs today tell the bios what they are and the system should set itself for you. I would call acer support and ask them if there is a trick to it for your motherboard. Where did you get your upgrade processor from?

 

Thanks for the reply.

I've sent an email to Acer, although I expect a "we don't aupport DIY improvements sir" type reply.

I downloaded a full version of Phoenix Winphlash and looked at the advanced settings and could find no mention of clock speed or multiplier.

Sandra shows the actual processor clock speed 12xx Hz), the correct processor type (Pentium M 1.7 740) and it's rated speed, but also the illusive 1.3 MHz original named speed of the latop, but I can't work out where Sandra is getting that last bit of information from!

Oh, I also left the thing with the BIOS battery out overnight incase there was some form of hidden setting.

Frustrating becuse I know it's there somewhere!

(Processor is new from a local chain of PC shops, APP Informatica)

 

Is it possible your OS has not detected the change in CPU's? The Device Manager has a Hardware ID for each device connected to the unit. It's possible the apps are getting the remaining info from here. Try re-detecting hardware in Device Manager and see if it finds a new CPU. You may even want to go the distance and remove the CPU from the list in Device Manager (not un-install, just delete) and let it re-detect at bootup. I've done this for HDD controllers and other devices, but never for a CPU, so try at your own risk. You may even want to try re-loading the OS (manually, not from restore CD's) on a spare notebook HDD if you have one and see if it works.

Good luck!

Thanks Venombite, but everything is fine there and the correct processor type and driver is installed. I removed / uninstalled and reinstalled the driver.

This is driving me nuts!

 

You could try a live linux distro, boot it up say knoppix, get in a terminal and type

cat /proc/cpuinfo

this will give your the raw CPU information.

Also if you bought a retail PM chip could you give me the Part number of the side of the box?

Now that I think about it I bet you need a microcode update. I'll see if my intel dev account is still open and get you the most update to date microcode.

 

Hi Dan. I've emailed with the processor info, but will try the linux distro as well. Thanks for the help.
