Hello! Boy this hasn't been my week, so here go's.... Bought an Acer T-180 for my daughter about a year ago.... came with an AMD 3800 athlon - swap out to a AMD 4000.... ran good.... now she WANTED a little better performance....OK.... saw a AMD 5200 & slapped it in(not literally).... posted fine.... but(I'm finally gettin to the question) the processor that shows in device manager is the old 4000.... OK I reset CMOS and reboot.... still shows the 4000 in device manger but, in the computer Hardware list it shows the 5200 & when I ran the Vista performance thing.... the calculations or CPU, went from 5.1 to 5.3.... so I think it's running @ spec.... is it? & how could it do this when device manager said the opposite...... running Vista Hom Basic 32Bit thanksJust a note.... I went to CPU-Z & bingo it shows to 5200.... Also went to Nvidia Control Panel & CPUID.- it's there also.... System runs fine ever if it doesn't show in Device Manager.... I didn't think that was possible, but I guess so!! Thanks Is it showing up okay in the BIOS?

Are you getting the performance boost from it?Hi Quantos! Yes it shows in the Bios.... & Yes there is a performance increase.... I ran the Windows Vista Performance test(or what-ever) CPU went from 5.1 to 5.3.... Just couldn't understand why it doesn't show in Device Manager.... Thanks The 'Device Manager' is Windows, it fails OCCASIONALLY. There's a utility called Everest that just rocks, let me find the link for you. It will tell you stuff about your computer that you didn't know existed.Here it is, it's called Everest.

This utility is amazing, and it's also free.Don't want to step on anyone's toes, but it sounds to me like device manager just didn't update the driver. As this driver isn't HUGELY important, it's not actually a problem.
If it concerns you, try this - it's the processor "drivers" to enable the Cool + Quiet feature, it may update the description shown to show the correct CPU.
Seriously though, it's not a problem, the CPU is RECOGNIZED properly and is performing fine.Good catch Calum.Boy I believe that Quantos! This problem can cause many(like myself)to think there's a problem when one doesn't exist!! which makes you waste time we may not have to waste!.... I've been using a program that looks pretty good.... PC Wizard.... Google it, you mite like it,lots of system info.... If your like me, I love the DETAILS!!!.... Thanks .... To Calum: Thanks for your input.... More info is always good & you make a good point.... Thanks for the Everest link Quantos, I'll be using it.... One good thing about a problem(s) - to find the solution.... gives in major experience & that's what it all about.... Thanks to you all.... GREAT INPUT!!!! I'm so glad that you found a solution, you come back any time now.Again as a Note: When I had cleared CMOS.... I had disabled COOL & QUIET in the bios than all ran well, but Device Manager still showed the old 4000..... Thanks again ALL!!Quote from: Quantos on July 04, 2009, 08:07:23 AM
