MSI K7N2 Delta - L won't run my AMD 2800+ at 333 FSB

[CowEyeball]

Yesterday I bought a K7N2 Delta-L and an AMD XP Barton 2800+ that can run at 333 FSB.

In my Bios I am allowed to set the processor FSB up to 200, and no faster. If I select 200 and reboot my monitor will not cut on and the computer will hang. The only way to recover from this is by setting the "Safe Mode 100MhZ" jumper on the motherboard, re-entering the Bios, and bringing her back down to 166.

When at 166 everything runs wonderfully, and I love what I've invested in. However the geek inside me wants 333, as I'm sure we here can all understand.

I flashed my Bios up to version 5.2, which did not change anything. Looking at the changelists of Bios versions it appears that the version I had, 5.1, included a fix offering 333 FSB support for 3200+ processors. Is it possible that unless the processor is 3200+ my board just assumes it cannot run at 333?

More nitty gritty for those who would want it:

Mobo: MSI K7N2 Delta-L nForce2
Proc: AXDA2800DKV4D Barton FSB 333 2088Mz .13u
Bios: W6579MS v.5.2
Memory: 512MB PC3200 Ex-Patriot 400Mhz

Thank you in advance,

I think you're misunderstanding here... 333 MHz FSB is 166 MHz only double pumped, that's how the AMD chips work, the Intel chips, they are quad pumped, hence you see 400, 533, and 800.

And if you plan to overclock, which is what your symptoms are for the blank screens, overclock little by little until you achieve the maximum

Excellent, so all is well.

Cow is learning, thank you for the reply.

Poopyhed2 is exactly right

I have the same mobo I think running bios v7.2 from MSI, and XP2800 Barton processor.

When in the Bios it is set @ 166 it will give you a 333mhz FSB

Use a program like SiSoftware Sandra 2003 and it will show you a more detailed listing of your setup.
