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.

Upgrade the 1.6GHz CPU on L7VMM2 Motherboard

ECS Support > L7VMM2 motherboard > Main Support page,

Click on the CPU tab.

(Features / Specification / Download / Support / FAQ / CPU / etc)

Will support Up To an AMD Athlon XP 2600+,

Maximum Front Side Bus support is 266Megahertz.
(Max FSB = 266MHz)

(Motherboard manual states 133MHz.
Note that AMD processors are 'Double-pumped'.
This = 266MHz )

Supports AMD Athlon, AMD Athlon XP, and AMD Duron, processors.

Note in the CPU Support chart where it states -
Socket 462 > AMD Athlon XP > 2600+ (.13u)
The .13u stands for 130nm core architecture technology.

(nm = NanoMeter.
1 Billionth of a Meter )

For the Socket 462 (Socket A) processors, the AMD Athlon XP models are the top of the line.

'Sempy', or Sempron processors are at the bottom.
Low L2 processor memory cache compared to Athlon XP or Duron models.

Can I upgrade my 1Ghz processor to a faster 2 or 3Ghz? I have an EliteGroup 741GX-M, socket 462 desktop with an AMD sempron

yes, it is possible, but the Front side bus will limit the functionality so much that it wouldn't be worth it.

The Ol' Asus A7V266-E?
1.The fastest Front Side Bus setting is 266MHz
2.Uses Socket 462 AMD processors
3.Uses Athlon, Athlon XP, and Duron AMD processors.

I would stick with an AMD Athlon XP. Fastest one? Hmmm, I believe that would be the AMD Athlon XP 2600+
The one that operates at 2133MHz with a FSB of 266MHz. Part number AXDA2600DKV3C

Here is the Motherboard Manual for your Asus A7V266-E, (It's a PDF file download. Let it download all the way before looking through it)

If the above direct link does not work for you, then go here, (Click on -> Download <- all the way to the right of -> File:a7v266e-100.pdfVersion:--Release Date:--)

Go to Page 19, Item 2. NO POWER connected to computer, make sure the SYSCLK (System Clock) DIP switches are set to 133MHz.
1, 2, 3, and 4 are set to the OFF position for 133MHz.
All you will see is the ON. The switches go to the opposite side as shown in Item 2.

I'm sure they are set there however, as your 1900+ you have in right now, uses a 266MHz FSB.
I should explain.
AMD processors are Double-Pumped. Therefore the 133MHz setting will become 266MHz for the processor. (Intel processors are Quad-Pumped.

They are both the same Core, (Thoroughbred A/B, Model 8, 130nm), so a BIOS update shouldn't be necessary.

Athlon XP 3000+ is 400mhz FSB according to the link(,,30_118_1274_3734^11672,00.html), means that in order to display the actual speed of your Athlon XP 3000+ you have to set your board 166mhz to 200mhz jumper setting or in CMOS utility overclocking option. and also just to inform you that your motherboard is in Overclocked condition when set, because it only supports processors up to 333mhz FSB (
