The ADD is the 35 watt version.

I'm puzzled why the system is abruptly shutting down. It's not the temp and it shouldn't be power. I tested it with a 500 watt power supply.

I keep thinking it might be the cpu itself but I have to keep reminding myself that the system will run forever if I'm into the bios and temps are good. Would that not eliminate the cpu being bad?

Cheers

My memory didn't server me well, you are correct. I have run the ADD version in several different EX470's without any problems at all. I don't see that it would be a heat or wattage problem since it is only 35 watts which is the same as the original processor. Did you recheck the bios mods to insure you are handling the processor correctly?

I'm assuming that the bios mod worked since on the bootup screen it does identify the cpu as a dual core 4200+. Also the mod went exactly as outlined in the instructions but still it might be worth doing it again.

Cheers

I just flashed the system with the stock bios and it still identifies the cpu as a dual core 4200+. I did verify the contents of both the stock and modded bios and they match 100% with the instructions.

I reflashed a number of times with the same results. I think I'll d/l all the files again and start all over.

I wish I had another mb to verify that this cpu is good or bad.

I d/l all the files from this site again and did the mod but no change. Appox 30 seconds into the boot and the system shuts down.

Did you use Artic Silver or equivalent for the processor heat sink and is the heatsink set correctly against the processor. Try putting a household fan blowing in the open door when you boot up to see if it is successful. Sometimes individual machines can be quite picky, but there really should be no difference between the original processor and the 4200+. I know I had a heck of a time with the bigger processors but just kept rebooting until it ran and overtime actually became stable.

Yes I did use Artic Silver and yes I'm using a large fan pointed at the cpu heat sink, the whole system has been removed from the case. Also remember in my earlier message I mentioned that I could get into the bios and hang around in there for as long as I liked. Also the temps indicated in the bios were normal and remained steady. However, as soon as I exited the bios the system would shutdown. That really puzzles me, why the system can run indefinitely in bios but once Windows starts the system shuts down.

Pretty dead around here.

I got a hold of a dual core BE-2300 1.9ghz cpu and it runs fine with cpu-z indicating 2 cores.

Now my question is, is this enough proof that the 4200+ is faulty?

Cheers

I would say if the BE2300 which is a decent processor for the EX470 is running without issue then there could be an issue with the 4200+.

I would review the BIOS MODs to make certain everything checks out and then I would test the processor out in another unit to see if the problem occurs in another unit or not. If the problem occurs then I would RMA the processor with AMD. You may want to attempt to RMA the processor as it stands but keep in mind that if along the way AMD made changes to the processor that the EX470 was sensitive to then that could be the cause of the shut down. I am not upto speed with the 4200+ or if revisions were made to it or not but it might also be worth looking into.

I wish I had another unit or an AM2 motherboard to test the 4200+ but I don't and that's why I have doubt.

Happy to report that the BE-2300 has been running flawlessly.


Cheers

FWIW The BE2400 -- which is similarly spec'd to the 4200+ -- wouldn't run in my EX470 either...

Personally, I would just accept it for what it is...

Yet another X2 3800+ ADD chip for $10 BIN on Ebay - snag it if you want it !

Darn! I was out of town for a week and missed this. Good deal.

I have run the BE2300 in EX470's and now of course I have the ADD3800+ running in 2 and soon a 3rd but to be honest I do not see much difference between the two. Of course the lower wattage in the ADD3800+ is more favorable.

Hi guys, firstly let me say thank you to all that have contributed to this post. I discovered this a couple of days ago and its been an incredible source of information.

I found a BE2300 for sale on ebay (shipped from Hong Kong so it will be a while before it gets here) and thought I'd get started with the bios update.

Before I started however, I thought I'd check the current cpu temp with the stock Sempron. I was gobsmacked to see it at 51'c while idle. My question is, is this normal (i'm guessing not) and should I be worried or just plough on with the upgrade and hope the new processor is at least as cool, if not cooler than the current one.

Could it be something as simple as the heatsink not seated on the processor correctly. The machine is currently as shipped from the factory albeit several years old now.

Many thanks for your help.
