Upgrading AMD cpu

I need help in finding what AMD chip is compatible with my ASUS motherboard. Already contacted ASUS and AMD....not alot of help with them!!! ASUS mb model-M2NC51-AR. My AMD chip is ATHALON 64x2 3800+ and I want to upgrade to no more than a 5200+, due to mb wattage restrictions (65 watt max). I am currently running Vista Premium 32bit, but will be getting the 64bit full version soon.

Re: upgrading AMD cpu

There's two versions of the 5200+, one rated at 89 watts, and the other rated at 65 watts. 89 watt version: ADA5200CSBOX or ADA5200IAA6CS, F2 stepping, 1.30V/1.35V 65 watt version: ADO5200CZBOX or ADO5200IAA6CZ, F3 stepping, 1.20V/1.25V Make sure it starts with ADO, not ADA. There's still a lot of the 89W version in the channel, and not many of the new one. NewEgg currently has the F2 (89W) stepping in-stock for $124, and the model you want will likely be priced similarly, when available. They currently have (in-stock) a 5000+ for $120, that is 65W. If you want it ASAP, go with the 5000+ (ADO5000DDBOX). I would recommend getting the retail-box version, which comes with a new heatsink/fan and warranty; this assures you that the heatsink/fan is an appropriate match for the CPU. Note, depending on what RAM you have installed, this may bottleneck the CPU. For full potential, make sure you're running DDR2 PC-5300 (667mhz) memory. You should be able to get a 2GB "dual-channel kit" (matched pair of 1GB sticks) for around $60-70. Definitely run at least 2GB total for Vista; unfortunately, your motherboard cannot go past 2GB. Similarly, you may want to get a new video card (PCI Express x16), but don't bother going all out here.. the system will never realize the full potential. I would target $100-150 for a video card.

I currently have a Asus Motherboard, 600W and a AMD Dual Core, 2.4ghz CPU. I would like to upgrade the processor chip but as I don't have the motherboard manual I don't know what kind of upgrade I can...

What you need here is the socket type of your CPU. To find that we need the model number of the chip, which can (hopefully) be found by opening the control panel, then going to Hardware and Sound, then to the device manager. Look under the heading for Processors. If you google whatever name is there, you should be able to find a listing that tells which socket it uses. If that fails and your computer isn't a custom, you should be able to search for your model number and find some system specs online. Any other CPU that fits in the same socket will work. All of those CPUs will also be made by AMD.

What is the best available compatible chip for ASUS A8V-E SE?

Go to the Asus website. Click on the support link. Lookup your specific motherboard model #. Once you have located this there will be a menu in the left hand side that will say cpu support. Click on this & it will list all cpu's that are compatible with your board and what bios version you would need to run with each cpu. Hope this helps.

Finding a compatible motherboard and processor

The DDR1 is now Obsolete. I suggest you to purchase entire motherboard with processor, RAM and graphics card. As it is one time investment, try purchasing Quad-Core CPU's with atleast 4GB of RAM.

Problem with upgrading processor

Sounds like the processor you're trying to upgrade to isn't the same frequency. The processor, motherboard, and memory have a matched frequency. For example; a motherboard with a frequency of say PC4200 will only accept a processor and memory of a PC4200 frequency. If you try to use PC5300 memory it basically won't do anything, blank screen, or maybe a beep. The same if you tried to use a processor with PC5300 on the PC4200 board. The best way to find the frequency rating is to look on the memory. They class the memory by frequency, but rarely ever list the frequency for the board or processor. Research the new processor to find out the memory class and then see if it matches the memory in your machine. If it doesn't then the processor won't work. If it does, then new processor may not be compatible, and that means more research.

Upgrading processor to Duron 1.4GHz

well older mother board cant handle a higher CPU processor, you have to make sure you have ALL the jumper properly set for the CPU, also the memory on the motherboard should be for that motherboard. try not to OC the motherboard as it will fry it.

Also check the motherboard for any Blown capacitor. for the MB to scream bloody murder something is definately wrong.

you could check the website of asus and look under ARCHIVE or DISCONTINUED motherboard. to find drivers and manuals for the motherboard you have unless you have them

also make sure the motherboard can actully take a higher processor.

A8V-MXs are built for AMD processors. You will need a board made for Intel processors if you want to purchase the above processor. If you want to stick with Intel and Asus check out the P5 series of boards. If not, buy an AMD chip...I've had AMD in almost every one of my computers, laptops and desktops.

Good luck.
