Abit KX7-333 Raid Ver 1.0 CPU Support

nospam · Oct 2, 2003

What is the Highest CPU people have running in this board, according to Abit ver 1.0 does not support Thoroughbred processors.

I am currently running a 2000+ and would like to upgrade the CPU, thought I will proberly end up changing the board for an NF7-S and a 2800+.

The version v1.0 board does not support the 2200+ it will work with any other cpu up to 2600+ if you set it up manually. It won't support the 2800+ due to the lack of a 13.5 multiplier

MB's don't have any multipliers. They're defined on the cpu. And the XP multipliers go up to 24x. And he can get a 13.5 multiplier on the KX7-333. One just needs to know how. That said, his best option (at least easiest) would be a 2500+ Barton set to 12.5x166 or 2083MHz which is a 2800+. I've heard of some running the FSB much faster than that on this board, so it's possible he could get the speed up quite a bit more by raising the FSB past 166.

CPU surgery? or Running the CPU at exotic fsb?

Errm no, 12.5x166 gives you 2075MHz in BIOS and 2083MHz in Windows - I know, splitting hairs

And it's a 2600+ (333MHz) at that speed. I know, 'cos that's what I'm running here. The BIOS shows it as Athlon XP 2075MHz. Windows and CPU-Z report 2600+

True, although he may have a problem with AGP/PCI bus being run out of spec. Really depends on what's plugged in. As I'm sure you know, some devices are very unreliable if the bus speed is too high.

Cool! I couldn't get anything higher than a 1400 to work reliably in my old KT7A-R. So congrats to you for getting the extra mileage out of this board.

Right-ee-oh...

Additionally, you need PC2700 RAM as well as you can't set the FSB to 166 unless you have memory that will run at 166 MHz (333 DDR). Also must set divider to 5:2:1.

My FSB is 187 MHz and am using a Duron 1G processor, Kingston HyperX PC3000 memory at CL2.

Chabging the FSB won't change the multiplier, and cpu surgery isn't needed either.

Er, yes. 12.5x166 is actually 12.5x166.67 (nominal). Use your calculator. I just assumed everyone knew that.

And it's a 2600+ (333MHz) at that speed. I know, 'cos that's what I'm running here. The BIOS shows it as Athlon XP 2075MHz. Windows and CPU-Z report 2600+

A Barton core run at 2083MHz is rated as a 2800+. You are either wrong, or your bios is wrong. Now a Tbred core run at 12.5x166 is rated as a 2600+. But we're not talking about a tbred core.

It's not magic.

What then? Please explain, I'd really like to know

hehe now who's splitting hairs? - btw my BIOS obviously doesn't like fractions that require a vinculum - thankfully, Windows saves the day, and gives me back my missing MHz

And it's a 2600+ (333MHz) at that speed. I know, 'cos that's what I'm

Oops! Sorry, I was referring to my tbred 2600+ I missed the magic "Barton" word

Maybe not but there's also luck involved sometimes

Pin mod, or adding a switch for the 5th multiplier bit.
