Hey there. I was just wondering if anyone could help me out with this question i have about my new laptop i bought last week.
It is a compaq notebook with the new AMD Turion 64 Mobile Technology ML-32 processor.
Its advertised speed is 1.8Ghz
I decided to open up the system properties by right click in 'my computer'. It showed up as 1.79 which was fine. but i check every now and again and lately it comes up as 796Mhz in the system properties. I thought oh well this could just be a problem with it showing up not an actual reflection of the speed. I went to install Age of Empires 3 which has a minimum requirement of 1.4 so i thought yep thats fine. As i was installing it said i do not meet the minimum requirements and was seeing the computer as 0.8ghz. it said i could try and run the game anyway so i did and it seemed to work ok.
I only bought the computer 6 days ago and have been checking the system properties regularly. At the moment it shows up as 1.79 but last night was showing up at ~797. so it keeps changing back and fourth.
I did a bit of reading about it and someone suggested start>run>dxdiag
and it came up as the processor being ~1.8GHz
I also download the diagnostic tool called Sandra which was recommend on a help site also and the system summary in that brings up the processor @795MHz.
So as you can see i am really confused and am wondering if I have got what I really paid for. What do you guys reckon is going on. Do you have anything else i could try?
Thanks for your help
