presario r3000z's xp-m processor specs..

the specs on these processors are not close to what i had read about before. i was looking for an a64 desktop build on a DTR chip so i'd read about the xp-m chips as well.

they list the xp-m 2800+ as 1.6ghz with 128k L2? that is a huge difference from the higher clickspeed and 4x L2 that i knew about. i called hp to see if it was true, and it was..

yet the a64 3000+ chip that i looked at had 1mb l2 cache, and the one hp is putting into these systems also does.

so are their xp-m chips very outdated versions, while the a64 chips are the current (clawhammer core) ones?

Some of these Athlon XP-M I believe are based on the A64 with their 64bit disabled and the cache disabled but there are others which were left over Athlon XP chips (may not be the case anymore). Semprons have taken over that role but AMD still make some XP-M for OEM's. I think Hp puts the decontended A64's as XP-M at a lower price..

so the xp-m 2800+ with 128k L2 is an old xp-m chip, and it's the newer ones, based on the a64s, that have 512k and higher clockspeeds? those must be the ones i had been reading about, then.

either way it was a cheap upgrade for a nice clawhammer core

I think the XP-M on the R3000/zv5000 series used by Hp may be the cut down version of Athlon 64..I dont know why they still call it as AXP-M rather than the Sempron.
It makes sense since both are of the same socket(754)...they can use the same motherboard. I read on another forum that they probably use 2 - one without the media card reader and the 32MB Go440 and the other with the 64MB Go440 & the 5 in 1 MC reader. Theoretically you should be able to swap in the 2 processors.

Try CPU-z, it probably will tell you if the processor is S754 or Socket A.

i don't think that they use the same motherboard..

when i upgraded from the xp-m 2800 to the a64 3000, it made me upgrade to the gef4 440 go 64mb (which i wanted anyway, but still).

a cut down a64 processor would have more than 128k l2 cache.. the a64s have 1mb! and the clockspeed should be the same if it was the same processor with 1/2 bad l2 cache that they disabled.

Not necessarily! They can disable as much cache as they want.They want to differentiate between these and the A64's so they just disabled the 64 bit instructions, cut down the cache and reduced the clock speed to slow it down just enough for prople to want to upgrade to the A64.

Yep! Hp uses 2 motherboards as I said in my last post.

Do check out www.r3000forums.com specific forum for the ZV5000/R3000 laptops.
