Pc slowed down after cpu upgrade


Jan 23, 2010
Hi all,
I just installed an ATHLON 64 x2 (dual core) 4400+ processor on my MSI K8N Neo4 Platinum/SLI motherboard. previous i had a single core AThlon 64 3700+. With the new processor th epc seems to have become slower the cpu usage in frequently to 100%, in my opinion for no use. have anyone an idea on what could be the problem?
thanks for your help.
You most likely need either the AMD dual core optimizer or the Windows XP dual-core patch (either of which fixes certain system timing issues when moving from one to two cores ...)

IIRC, you don't need to install both of them --- that creates additional issues.
