Upgrading AMD Socket A Athlon 1200 to XP 2400

I recently secured a socket A, Athlon XP 2400 to upgrade my current system, mobo stats for my ECS K7S5A says that should be compatible at 266 fsb. I plugged it in and no boot; fans spin, lights glow, but no boot. After two tries I reinserted my original slow, but steady processor. I have uploaded my WCPUID screen shot of my current cpu. Any constructive input would be greatly appreciated.

 

My first suggestion would be to clear the cmos, unplug power supply, pull mother board battery out for a few minutes then put back in, see if it will post. I guess there is a possibilty that the xp is bad. ed

 

Thanks Ed; again no luck with posting. Someone mentioned to me that it might be a cpu voltage issue. He said that possibly my athlon 1200 cpu was a model 4 versus a model 6 or 8 for the athlon 2400 XP. As a consequence, the cpu voltages would be different and incompatible with my mobo. You ever heard of that, I don't know how to tell if I was bein' fed a line of $%@^ or not. Is there a method to determine models for amd socket A processors from SN or something visually?

 

In my quest to solve my cpu problem, I believe that I found a way of identifying AMD processors that might be of interest to others:

AMD CPU Processor Identification
-----------------------------------------------
AXDA 3200 D K V 4 E
AXDA Architecture Segment:
AXDA = AMD Athlon™ XP Processor ("Barton"/"Thoroughbred")
AXDC = AMD Athlon™ XP Processor ("Thorton")
AX = AMD Athlon™ XP Processor ("Palomino")
3200 Model Number: 1500+ to 3200+ and above
D Package Type: D = OPGA
K Operating Voltage:
L = 1.50V
U = 1.60V
K = 1.65V
M = 1.75V
V Die Temperature:
T = 90 Degrees Celsius
V = 85 Degrees Celsius
4 Size of L2 Cache:
3 = 256KB
4 = 512KB
E Max FSB:
C = 266MHz
D = 333MHz
E = 400MHz

 

Have you looked into seeing if there is an updated bios for your motherboard, that may fix this issue?

Also, if memory serves me (rarely does), there may be a jumper on the board that enables newer cpus to be run as they should. May have to check the motherboard manual.

Do you know for a FACT that this cpu is a good one?

 

Agreed that the original cpu, 1200, is a Thunderbird with voltage at 1.85 and that the cpu which you are trying to use is an XP Thoroughbred whose voltage is 1.65v.

In the first instance, I would clear the bios and put the new cpu in, given that if will not boot with the new cpu. Hopefully, the bios will auto detect correctly after this. The specs to your board state that it can handle up to XP2600 so in theory (and practise) this new cpu should work fine. As has also been stated you may need to flash the bios.

Good Luck
