Mobile Bartons for your desktop rig.

edited February 2004 in Hardware
I decided to do a little experimenting before I went out to work offshore 2 weeks ago and ordered a mobile XP2400+ so that it would be waiting for me when I got in this time. I got in yesterday and started looking at it and sure enough, it is a barton core, IQXEA 0330. I had a rig sitting with no proc in it, due to the fact that I had robbed the proc out of it to get my Chaintech dually in operation, so the KHA+ mobo was to be my initial test mule. I installed the proc in it, along with the 8045 heatsink I had been using in that rig with an 80 mm Sunon case fan, and booted up. It booted up at 800 MHz, since the proc has a 6 multi set on the L3 bridges; the hi/lo sense must be detected via the L5 bridges on mobile boards, due to the dynamic speed changes involved with the laptop XP's in their various running states. I then entered bios and set a 12.5 multi on this old board, since it can't set a higher multi without modding the proc and rebooted. It then came up using a 12.5 multi and booted normally. I presently have it running at 155 X 12.5 in that old KHA+ rig using it's default vcore of 1.575v and folding normally at 34C. And this is just with a crappy old normal Sunon fan, not the low speed Delta FFB I used to use with that heatsink because I'm presently using that fan on the dually.

Today after I get back from my Father-In-Law's wake(he died Friday, from cancer:sad2: ) I will be pulling the proc from the KHA+ and putting it into my NF7-S and I'll see what it will really do.

These procs might just be the ticket to go with since AMD, in their infinite farqing wisdom:rolleyes2 , decided to start locking their new proc's multipliers.

    Wow, thanks for the info. Let us know what it can do in your NF7-S. :)

    Here are a few pics of this proc.

    Here is the label, blown up to where it's easy to read.

    Here are the top side bridges. If you look, you will see that the mobile proc has some different bridges burned on the L5 and L12 bridge parts. I think that this is to enable the mobile speed adjustments and also maybe to alter the vcore with it. Also note that the right-most L5 bridge is intact, but that doesn't enable SMP operation because the next one over isn't cut also. .A guy over at overclockers.com has tried them in a K7D Master-L and it would only run them as a dual when he blew the 3rd L5 bridge.

    Excuse the fuzzies on the pics; I was dead tired when I had gotten in from the rig and did this and didn't do the most thorough job of cleaning the stickies off after removing that damn sticker newegg had put across the bridges.:scratch:

    I have seen a few ones before and none went past 2.5 unfortunatly and they HATE voltages. But it's a cool running cpu, that's for sure. I think the default voltage is 1.4 or even less.

    Keep us updated and sorry for the loss.

    Finally, here is a pic of the L6, L8 and L11 bridges. You will notice that there are some bridges burned on the L6 and L8 bridges, but it doesn't look like they are used at all on a pic I was checking at newegg on a desktop proc.

    Sorry to hear about your loss, mud. But please do let us know how it OCs... I've been thinking about trying it myself.

    Well, so far it's a decent but not great overclocker. So far, I've got it up to 11.5 X 205 and gromacs stable with 1.85v vcore. It does seem like it runs a few degrees cooler than my 2500 at the same clock speeds and vcore though.

    thanx for the update mudd, I think two of these chips will be ordered for my NF7-S boards.

    I have another one of these procs that should be arriving today; I'll be testing it out for the next few days too. I plan to use these in my watercooled Asus dually, pinmodding a 16 or 16.5 multi on it.

    OK, my new 2400m just arrived and here is a scan of it. As you can see, it is a brown 0319 proc:

    Well, so far this brownie is doing great. I just left my vcore running where it was at with the other proc and so far I've gotten this high with it. I'm abaout to bump the speed up another 50 MHz and see how it does.

    that cpu-z is with aircooling still?
  • muddocktormuddocktor
    edited November 2003
    Yeah, that's with a SLK800 with a 68 CFM Delta focused flow fan. It looks like that is pretty much the ceiling for that proc. I tried higher speeds but the vcore increase needed to stabilize it rose quite a bit and then I started having heat related stability problems. I imagine that proc could go another 100 MHz higher with a good watercooling setup though.

    EDIT: All in all, not bad for an $85 proc.:D

    what do ya think of newegg now listing it as a Thoroughbred but listing the same stepping "AXMH2400FQQ4C". Still a barton?
  • muddocktormuddocktor
    edited December 2003
    Basically, newegg doesn't know what this proc is, but the OPN on it, AXMH2400FQQ4C, tells you that it is a barton core by the "4" in it and a 266 fsb part by the "C" in it. It's the same code that is on both of the mobile 2400's I bought. A Tbred core will have a "3" instead of the "4" in the processor code. 3=256k L2 cache, 4=512k L2 cache.

    EDIT: Fixed typo.:doh:

    typo? I don't see a "D" in that code...

    Just curious mudd,

    Is there any special process that goes into installing a mobile processor or is the same as any other athlon xp? Is there any modding required? Also, to overclock it is there any modding or is can all overclocking be done without doing modifications to the chip?

    I'm extremely interested in buying one of these as my temps are starting to annoy me and my 1800+ dissapointed me in my overclocking ventures.

    so.... yes?...or no?...i already new my mobo supported bartons...just didnt know about the mobile part...what makes a mobile proc mobile? the low vcore?..and thats an old Bios;)
  • csimoncsimon Acadiana Icrontian

    my guess is the low vcore is the biggest difference ...
