Question about AMD AXMJ2800FHQ4C - Athlon 2800+ XP-M 266MHz Processor

2 Answers

Athlon 2800+ XP-M runs at 606 MHz

I just bought a 2800+ mobile cpu. When inserted into system it will only run at 606MHz not the rated 2.13GHz. Motherboard is a Gigabyte 7VT600P-RZ(-C). will run anything faster than 1.4GHz, up to 400 FSB.Cannot find any way of increasing the multiplier. Ran Cpuz and it came back with: Core speed: 606MHz Multiplier: x6.0 FSB: 101.0MHz Bus Speed: 202.0MHz I tried the overclock program that came with my motherboard but it wouldn't let me change the multiplier settings. Do I need to reinstall windows? I assumed it would run default at 2.13GHz when inserted into motherboard, was I wrong in thinking this? Any help would be much appreciated as I don't want to go and spend more money on getting this thing working. Thanks. Mike.E

Trying to upgrade a Compaq SR1020NX computer. The HP website still has old info, likely based on the original bios. The motherboard is an Asus A8M2N-LA. What CPU upgrades will run on that board? Is there...

The ASUS A8M2N-LA is the motherboard used by HP for the new D4500e AMD AM2 PC.

Here are the details:
Motherboard manufacturer's name: ASUS A8M2N-LA
HP/Compaq name: Nodus-GL8E
CPU/Processor  Socket: AM2 Supports AMD Athlon 64, Athlon 64 X2, and Sempron processors
Front-side bus (FSB)  2000 MegaTransfers/second
Chipset  GeForce 6150 LE chipset
BIOS features  Award brand system BIOS Keyboard combination to used to enter BIOS: F1
Form factor  Micro-ATX: 9.6 in X 9.6 in
Memory  Four 240-pin DDR2 DIMM sockets, Supports PC 4200 (533 MHz) and PC2 5300 (667 MHz) DDR2 DIMMs, non-ECC memory only, unbuffered Maximum HP/Compaq approved memory is 4 GB*
PS - as you can see the rangeis 533 - 667 MHz. I would suggest you call HP support and ask if it will support 800 MHz,

How to get AMD athlon 3700 socket 754 engineering sample cpu run at proper speed

Here's a little history

More advanced stuff

Some systems have "bottlenecks," where small overclocking of a component can help realize the full potential of another component to a greater percentage than the limiting hardware is overclocked. For instance, many motherboards with AMD Athlon 64 processors limit the speed of four units of RAM to 333 MHz. However, the memory speed is computed by dividing the processor speed (which is a base number times a CPU multiplier, for instance 1.8 GHz is most likely 9x200 MHz) by a fixed integer such that, at stock speeds, the RAM would run at a clock rate near 333 MHz. Manipulating elements of how the processor speed is set (usually lowering the multiplier), one can often overclock the processor a small amount, around 100-200 MHz (less than 10%), and gain a RAM clock rate of 400 MHz (20% increase), releasing the full potential of the RAM.

AMD also produced x86 designs which competed with Intel on performance rather than price. In January 2002 the Pentium 4 gained a lead in sales and AMD marketing responded by giving their processors numeric suffixes approximating the clock rate that an AMD Thunderbird (and by inference a Pentium processor) would need to give matching performance, openly undermining the "megahertz myth".

How to get my CPU to run at the correct speed

Your FSB should be 400 MHz for the Athlon XP 3200+ processor.
CPU-Z shows your core speed at 1320 and your FSB at 241. If you multiply those numbers by 1.66, you get 2200 and 400. So all you have to do is get the board to the correct FSB speed of 400 and your core will be right.
There are two MSI boards with the number CPU-Z gives you. Board 1
Board two

The AMD page doesn't show the core voltage for the older processors, they do for the current ones. I looked at the MSI site and didn't see their manuals online for the motherboards either, sorry. I'm not positive it was changed using a jumper though, you saw nothing in the BIOS to set it? If the jumpers are on the board they may be labeled FSB and you can try the various positions.

Hope that helps, good luck.

You motherboard uses a "Socket A" CPU and therefore has limits to how high you can go.. I would recommend the XP 2200 or 2400+ as a good choice, but you can make your own choice.

AMD Athon XP 2600 dropped speed

Some times when a computer shuts down unexspectedly like that it will reset itself back to its defaults in bios thinking there was a problem. Go in there and check your cpu settings. The fsb should be set to 266 mhz. Make sure it didnt default back to 133 mhz.

And FYI the 2600 is acutally a 2.13 gig cpu not a 2.6 gig..
