I upgraded the CPU on my Abit KR7A Socket A 266MHz motherboard from a AMD Athlon XP 1700 to a 2600 which was the highest Athlon XP chip to support 266MHz, but it doesn't work. Any suggestions?

    The computer will not post. The fans run and that's it. Do you think the motherboard might be fried? The computer kept shutting off and back on occasionally so I thought I had a virus or a bad hard drive at first, but these checked out okay. That's when I decided to check the CPU core temperature in the BIOS and found it was nearly 180 deg.F! It was still working, however, when I shut it down to blow the dust out of it and noticed that the CPU had become brittle and was disintegrating before my eyes. I upgraded the CPU, but it still won't post. What do you think?

    Okay...I did some of the suggested tests. The CPU looks okay under a magnifying glass, and was guaranteed to have tested good before it was shipped. I reseated it and it plugs easily into the socket. The original PSU (250Watt) was replaced with a more powerful one (350Watt) a couple of years ago, so I'm pretty sure it should be able to handle the new CPU (which is really still an old and obsolete CPU). I removed the memory, took out all the cards, unplugged the hard drives and made sure the PC speaker was plugged in, then turned it on. There were no beeps at all. A red light on the motherboard came on momentarily then flashed once if that means anything. I also noticed a slight burnt smell I hadn't noticed before. I think the motherboard fried along with the CPU. What do you think?

    David Kay pretty much already provided most of the info you need.

    To clarify though, do you mean it won't power on at all? As in no Post?
    Or do you mean the OS won't boot?

Under no circumstances should any CPU get that hot with proper cooling and functioning hardware.


Unfortunately, the board is done. Sounds like there was a failure somewhere on the board that probably caused the old CPU to be messed up. The bad news is that the new CPU may be jacked up if the board was bad and there's a burning smell. Even though the chip may look okay visibly, doesn't mean that it is.

Scrap the board and try to sell the CPU as-is and start from scratch. Socket A isn't all that common anymore and newer boards with a higher frequency bandwidth are pretty cheap and getting cheaper by the day.

I suggest You could easily get a new mobo and cpu for well under $100.

Hi Kaufam,

I'm sure you already know this, but it might be worth plugging in your pc speaker (if not already) unplugging your memory chips, hard-drive cables and all pci/agp cards and trying to see if the computer beeps at you during start up. You can then use these beeps on a lookup table on the motherboards manual to determine the error.

I hope this helps, otherwise try reseating it (again I'm sure you'll have tried this), try the chip in another board if you have one, ensure the PSU is powerful enough to power it (stupid I know!), and lastly you could have been provided with a dud chip, return to sended and hope for a working one. :(

Sorry I couldn't help much more than the obvious.

I have just purchased a AMD Athlon? 64 X2 4400+, 2.2 GHz and installed in a imedia Board: NEC COMPUTERS INTERNATIONAL MS-7168 1.0 Bus Clock: 200 megahertz BIOS: American Megatrends Inc. V3.07 do i need to...

It looks as though my resources were incorrect, as far as the two motherboards having the same processor socket.
(MSI RS480M uses a Socket 754)

What does concern me, is if the motherboard chipset used is the same. This was the stated information.

The motherboard chipset consists of the Northbridge chip, and the Southbridge chip.

Chip, and Chipset are slang terms for IC. Integrated Circuit.

Viewing this motherboard diagram may help explain how the motherboard chipset comes into play,

[You can also type, one at a time, Northbridge (computing), Southbridge (computing), Comparison of AMD chipsets, in the Wikipedia search bar, to gain more knowledge]

The Northbridge chip determines what Processors can be used.
It also controls high speed graphics technology.
AGP and PCI Express being high speed graphics, not PCI.

Determines what Ram Memory is used, and what Southbridge chip is compatible with it.

Let's go back to basics, and see what Northbridge chip is on your motherboard.
Two ways.
One, it looks as though you may be using a tiny program such as CPU-Z, or Belarc Advisor.

If not, I would advise downloading the free, tiny program CPU-Z from
Can you install the old processor, (AMD Athlon 2.25GHz), and get your computer to work, or are you using it now?

After you have CPU-Z running, left-click on the Mainboard tab, and tell me what it states for Chipset. Also tell me what it states for Southbridge.

Second way.
Physically look at the Northbridge, and Southbridge chip. IF, they are not covered with a heatsink.

The Northbridge chip is usually a large chip, and is located close to the processor socket.
Most configurations are like this; Processor socket at the top of the motherboard, ram memory slots to the right, Northbridge chip below the processor socket.

Motherboard designers put the Southbridge chip all over the place. There is no usual spot.

It is my belief at the moment, that your Northbridge chip will not support dual core processors, such as an AMD Athlon 64 X2 4400+
Only Single core processors.
Once I know what Northbridge chip you have, we can determine what your CPU support is.

Cpu Upgrade on sr1750nx

The SR1750nx's has Socket 939 on it's mainboard, which isn't compatible with the X2 4050e, because it's for Socket AM2. The fastest processor you can put in it is the "Athlon 64 FX-60" I think, but I don't know if you can buy it anymore.
