I'm building an Asus A7v133 based system. My CPU is an Athlon 1 Gigabyte. During boot-up, the bios(?) reports the CPU spped to be 750Mhz.
The system runs just fine otherwise. The board has a cpu autodetect feature.
Any ideas?

 
Is your Athlon 1 gig DDR? if so the fsb wants setting to 133 in the bios, I suspect it is setting to default 100? As with a Non DDR processor?
More info please. Martin Just trying to help, sometimes falling short, I am only human after all.

Yes, as papa says,,,, you need to reset BIOS to 133 FSB.
By default, if your system hangs, your BIOS will reset to the 100 MHz FSB, so that overclockers who go to far have a system that will boot.
So, sometimes when Windows fails a boot, or your system just hangs at boot up, then the system will just enter BIOS. That is where most people panic, and just exit the BIOS, (AND SAVING), and saving at the fail-safe / default settings, or the 100 MHz FSB.
So, now your AMD 1000 MHz ( which was 7.5 x 133.3 = 1000) is now running at 750 MHz - or 7.5 x 100.

> Have your mainboard manual ready. Or, download the manual from Asus.
So, on boot up, hit DEL KEY. Enter the section of the BIOS where you set the CPU Speed. Adjust it to 133.
Save & Exit.
1000 MHz again.

 
Paparazi & Jakespeare,
Thanks for the quick replies.
You were correct! I corrected the bios, and all is well!

Also, take note that motherboard speed does NOT give way to the term DDR.

DDR stands for Double Data Rate, or more specifically, operates at twice the motherboard speed.

If the motherboard speed is 100MHz, a DDR ram module runs at 200MHz.

If the motherboard speed is 133MHz, a DDR ram module runs at 266MHz.


DDR in no way descripes a CPU, it solely describes the type of memory modules that can be supported by a motherboard.
 
Yes I take your point and of course technically you are correct, but these are common terms banted around and terms that most people understand and refer only to the fact that particular hardware items run better in certain configurations: Alla , DDR motherboard, DDR memory, DDR processor, just general terms and as you say not technically correct.
