Hey there, as you may know I'm the one who is keeping his socket A running, I decided to get a new CPU for it as my Athlon 2600 has a heavily worn insulator on it, and after it's 4 years of service I think it's time it had a well deserved break.
So I found a 2600+ Sempron today whilst at a mates house and now I want to find out the differences between the two Sempron 2600s I now currently hold. I will start googling etc now but if somebody knows which is the better chip it'd be much appreciated if you could say which.

I drew up a quick MSpaint diagram of the chip information, the location of the "Assembled in Malaysia" text is different, my old Sempron having it printed with the other chipset information, and the new one having it written onto the CPU itself. Help is much appreciated, I'm now just waiting for my damn motherboard to get here so I can start it back up; hence why I'm trying to track down which is the better Sempron to use.

Edit: I know about AMD locking the multiplier on Athlons that were built after the 38th week of 2003, my Athlon is dated as the 11th week of 2004, so it's not worth trying to overclock that one instead. Maybe one of the Semprons is an non-locked chip and that is what I hope to find out. Thanks.

I don't believe there is any difference other than when they were produced. Just wait until you get the mobo and try each chip, read from cpuz or everest.

the difference i can see is manufacturing dates.

edit:

seems i found a difference, they were two different 2600 released.

http://www.cpu-world.com/CPUs/K7/AMD-Sempron 2600+ - SDA2600DUT3D (SDA2600BOX).html

http://www.cpu-world.com/CPUs/K7/AMD-Sempron 2600+ - SDC2600DUT3D (SDC2600BOX).html

The 28104 uses the Thorton (http://www.cpu-world.com/Cores/Thorton.html), while the 27648 uses Thoroughbred (http://www.cpu-world.com/Cores/Thoroughbred.html)

Go with the 28104, its based on the barton core.

I have one of each type of stepping used for the Sempron, that being the BIXJ and also a BCXJ. I can't make out the manufacturing date in the code like I can with the Athlons. Trying to find that now.

Oh yeah, I can run a CPU-Z report on each chip as I'm on my brothers socket A system now. I don't know if it'll provide any insight though?

All semprons are locked chips unless its a engineering sample. If the core color is bluish white good chance it does 200FSB at 1.65 to 1.7v. If its reddish color may be does but needs atleast 1.75V. I bought a semp 2500 which was reddish at it did 200FSB at 1.75V. Load temps were 45C on a ABIT board. Not bad. But it still struggled. Not quite good like the 512KB barton. So try to see the FSB jumpers like I mentioned in ur other thread.

Both are red cores. KTR - I also think that the 28104 will be the better one to go with just because it was in essence the last socket A made, up until the 7th of January 2006. The motherboard I'll be getting is a remade Gigabyte VT600. I know that the nForce chipset was the best socket A board but they are so rare now and all I've seen are used. I would consider buying a recently built second hand computer part but not something that could be at least 24 months old.
I have a Thermaltake SilentBoost for the board, left over from my original build. Is a pretty solid heatsink but I could try a Zalman I saw for socket A. Thanks for all the help in fidning info on these mateys.

I am going to upgrade my in-laws computer from ABIT NF7-S2G and Sempy 2500. That board is excellent overclocker and runs cool. But its not going to be immediately. I gave that PC last year. I have more S754 stuff lying around so I will build them with S754 and toss the Socket A to mother earth.
