Windows 7 - Upgrading my CPU with Win 7 64 bit

I was just talking to AMD the other day and I found out what all my problems with Windows 7 after doing a stress test and seeing that CPU 0 failed. I was told by the tech from AMD that the main core is starting to fail so I need to replace it ASAP can someone tell my the bust CPU for my computer here's my choices:
AMD Athlon 64 X2 Dual core 6000+ 3GHz
AMD Athlon 64 X2 Dual core 6400+ 3.2GHz

I am able to still get both CPU's on E-bay cheap but not sure what one is the best to get to give me the best performance with Win 7 64bit.

Here's the spec's of my computer

Windows 7 Ultimate x64 SP1
AMD Athlon 64 X2 Dual core 3800+ 2GHz
AMD Sapphire PURE CrossFireX 770 model PC-AM2RX780
8GB DDR2 800MHz
ATI Radeon HD5450 1GB DDR 2
Onboard 7.1 channel sound
LG Flatron W1953T 19 inch wide screen LCD
2 WD Blue 500GB 7200rpm hard drives 1TB in total
COOLER MASTER eXtreme 500 Watt

If your motherboard can handle it, get the 6400+. The faster it is the better performance you'll get. You might also want to consider an upgrade kit.

I was told by the computer shop that as along as I get a CPU that came out before my installed BIOS I should be fine the BIOS date is 03/03/2008 and this CPU came out in 2006. I also seen a picture of the same motherboard as I have and this guy had the 6400+ installed. The picture was from CPU-Z. Thanks for your help.

I caution you concerning buying on E-Bay. Oftentimes sellers offer what it is you are looking for at a very attractive price but if you have a problem they are not willing to assist you.

Buying from a reputable (even local?) source is no guarantee that you will not be "burnt" but at least you have done what you could to protect your investment.

This is true but the thing I like about paying with Paypal I am covered also I look at all the feed back before I buy from anyone. Also none of the store around here sell any AM2 CPU's anymore only AM3.

Buying on eBay is fine as long as you check out the seller's feedback and Paypal protects you pretty well so no worries there. And if there's a problem there's a very large forum here to help you out with it anyway haha

Seeing as you asked,

How about none of the above. This is from the CPU supported list for your motherboard,



Of the Phenom II's still available this,

Newegg.ca - AMD Phenom II X4 925 Deneb 2.8GHz 4 x 512KB L2 Cache 6MB L3 Cache Socket AM3 95W Quad-Core Processor HDX925WFGIBOX

would be the best your motherboard could support.

Remember to update the bios.

By what I am reading about this motherboard it might support the newer AM3 CPU's with a BIOS update but when I go to the Sapphire site and download the BIOS update all I get is the BIOS update don't support my OS. so I tried to install Vista same problem. I installed XP Home and it looked like it worked but when I checked my BIOS date it still says the same date. Also the BIOS date and version don't match any of the versions on the Sapphire site so my guess I need to find out who makes this board and go to their site for the BIOS update. Can anyone help me with this problem cause it would be just as easy to update the BIOS and buy a CPU from the computer store.

The BIOS update utility must be run under DOS.

There's a utility available for download with the BIOS files that allow you to make a USB flash drive bootable. It may be possible to do it from floppies, but I recommend the flash drive.
