Small CPU Problem

[Shinei]

Okay, so I have a 2800+ Barton, week 20. Multiplier is 12.5x, bus should be 166, right? Well, either my GA-7N400 Pro2 is damaged or there's something I'm not seeing wrong, because the system will NOT boot if I change the bus to anything over 100, and I can't change the multiplier in the BIOS. I've hit the clk_sw switch by the northbridge fan connector in both directions and it defaults to 100 MHz regardless of what I do.
So right now, a 2.08GHz processor is registering to Windows as a 1.25GHz processor and is definitely not taking advantage of my $241 gig of Mushkin PC3500. Am I missing something in the BIOS that will let me fix these problems, or is my CPU just plain damaged?

Some boards have a jumper that locks it at 100MHz FSB and will only do the upper frequencies when set correctly. Some manufactures use this as a safety when the machine may get locked-up due to overclocking.

Its a board jumper, not a bios setting, so if your are looking in bios for the problem, this would be why you missed it. The manual will show it somewhere if does exsist.

Oh, so the 7N series doesn't have a BIOS-based multiplier option? It was my impression that it did... Thanks for the information though, off to figure out why the hell I can't get a Windows Update or register my copy of Norton 2003.

I did'nt mean to imply your board does'nt. Some boards do have a board jumper for failsafe and also the settings in bios. The board jumper over-rides any FSB setting you may have selected in bios.

Looking at pictures of your board, I see it has a blue select switch of some sort by the northbridge fan header. That looks to be near the same place other manufactures put their 100MHz/133,166,200MHz jumper. Check that out.

I already did, it came in the "off" position (towards the bottom of the case), which the manual lists as forcing a 100MHz bus. I flipped it "on" (towards the top of the case), which the manual lists as "auto" (supports 266/333/400), and neither switch setting lets me clock over 100 without forcing me to reset the CMOS by popping the battery out.
