I bought a velicoraptor and reinstalled vista with the 64bit to get full use of my 6gb of ram but in cpu-z my core speed for the i7 keeps going from 1600MHz to 2800 MHz but mostly staying at 1600MHz. When I was running 32bit vista I had a constant 2800MHz core speed. Did I do something wrong???
That is normal. The i7 lowers the multiplier when it has little to do. It is one way to save power. If you go to the control panel/power options/change plan settings/processor power management you can select the minimum and maximum percent for the processor state. You want the max at 100%. If you always want to see 2800, then set the min to 100% also. It is probably better to leave it at 50% or the default.
Its a normal thing. Its Intels energy saving feature. What it does, and its in all Core 2s as weel, is it lowers the multiplier when you are not heavily using the CPU. Now I believe that Core i7 has a bit more advanced version that watches the CPU load itself and determins how high it needs to go.
But with most if the CPU sees a 20% load it will ramp the multiplier back up to max for optimal performance. It wont hurt a thing but will use less power when idle or doing minimal tasks such as web browsing.
Thanks all and yes I am very newb at the bios and all that, but trying to learn about it hence why I joined the forum and I must admit this forum is amazing and everyone is super helpful. Thanks for dealing with my newbie questions.
