Which is the best CPU out of these two?

[magick]

I know someone who's selling two cpus at the same price that will fit one of my machines. Which is the best?

Athlon XP "Thoroughbred A/B" (Model 8, 130 nm)
Athlon XP 2400+ (2000 MHz) 256 KiB 266 MT/s 15x 1.65 V 68.3 W (B) August 21, 2002 AXDA2400DKV3C

Athlon XP-M "Barton" Desktop Replacement
Athlon XP-M 2400+ (1800 MHz) 512 KiB 266 MT/s 13.5x 1.60 AXMA2400FUT4C

He says the first CPU is a barton but the product number on http://en.wikipedia.org/wiki/List_of_AMD_Athlon_XP_microprocessors says it's a thoroughbred.

Not to sure which to get because the thoroughbred is 200mhz faster but has 256kb less cache. Also, I think the xp-m barton comes unlocked? And therefore might have be close to death from being oc'd? He offers a 15 day guarentee on both of them.

Thanks.

My Barton didn't clock well for me, it all depends what you want to do with it really. Some things might want the extra cache.

I'm using it for running cubase and music production, so would the extra 256k cache be better than an extra 200mhz? As for clocking I'm not that concerned because I want to keep the machine quiet. If I get an extra 200 mhz I'll be happy though. Does the barton have an unlocked jultiplier? The only thing that concerns me is that if it has, the barton may have already been clocked to death.

The motherboard is an Asus A7V266-E and it does let you manualy select the multiplier. Thing is the multipliers go like this :-

5.0x/14.0x (single setting)

then 5.5x to 12.0x in 0.5 increments

12.5x/13.0x (single setting)

How on the manual setting can you switch between 5.0x and 14.0x or 12.5x and 13.0x? Would the MB automaticaly choose the highest?

And I've found a new processer that's straight out of a laptop :-

Athlon XP-M "Barton" (Mainstream, 45-53 W TDP, Socket A)
Athlon XP-M 2400+ (1800 MHz) 512 KiB 266 MT/s 13.5x 1.45v AXMH2400FQQ4C

It's multiplier is 13.5 which isn't on my motherboard so it be best at the 12.5x/13.0x multiplier for stability?

And it's voltage is 1.45v and my MB lowest setting is 1.70v so would it be safe to have a 1.45v CPU at 1.70v?

I used to run mine 12.5x with a 200MHz FSB (2.5GHz), by default the 'M' expects to see 333MHz but it can quite happily run at 400, or at least it's built to!

1.7v sounds very high, you sure that's your LOWEST?

To be honest I used to run mine at 1.55v and it was warm enough... with 1.7v you might crack 3GHz with that chip! lol

That's the lowest setting my mb has. Highest is 1.8 I think. Is it possible with a later athlon XP chip inside it will give options to run it lower, maybe it just says 1.7v because the xp1600 palomino I have in at the mintue needs 1.7v? Also FSB oc'ing isn't really an option because my mb is the older 266fsb.

Heres a pic from the bios :-

Many people run them higher than 1.7v. In the thread the pic is from the guy recommends setting the vcore to 1.65 but I'm running the same bios and have the same board rev and there's no 1.65 in the options.
