i just purchased a AMD 1GIG cpu. i installed it on a MSI motherboard. it's a MS-6340M. when i start it up it says it's a 750. what am i not doing? do i need to overclock it? i've invested next month's food allowance, i'd like to have something to show for it!
thanks for your time and help in advance.

Chances are you may have the incorrect multiplyer setting on your mainboard. Consult your mainboards documentation for the correct settings for your 1Ghz AMD.

If your multiplier settings are correct, then you may have gotten ripped off!  Did you purchase a sealed retail package or just a CPU w/ heatsink?  Its also possible that the vendor was selling "remarked" CPUs which have been overclocked.  To find out for sure, remove the heatsink (if you are comfortable doing this!  If you reattach it incorrectly, you're gonna be out of food and have a nifty AMD keychain!) On the second line of text on the core of the CPU (the black part in the center) it should say A1000xxxx (varies depending on the CPU), then under that will be another line, maybe AXIAxxxxx (again, variable).
*BE EXTREMELY CAREFUL REATTACHING THE HEATSINK*, if done incorrectly, you can crack the core and ruin the CPU!

Again, if you don't feel comfortable removing the heatsink, DON'T DO IT!

The multiplier on that chip is locked, so unless you did something on purpose (like solder a couple of the pins togetther!) the multiplier is OK.  I suspect that you have your Frontside Bus set at 100Mhz, not 133 (7.5 x 100 = 750; 7.5 x 133 = 1000).

Check the documentation for your motherboard on how to set this right - it will either be a BIOS option, or a jumper on the motherboard.

The MS-6340M seems to support 100MHz only, not 133. d_hall is correct, the 1GHz AMD Athlon comes in two flavours: 100MHz FSB with 10x multiplier or 133 MHz FSB with 7.5x mulitplier.

Now, you most certainly have bought the 133MHz FSB version, and run it at 100 MHz FSB, which gives exactly the 750 MHz. You should go to the shop and have it exchanged for a 100 MHz FSB version; in the case you specified what mainboard you're goint to use it with when you bought it, they did the mistake anyways.
