Intel T7250 2.0 GHz multiplier stuck at 2.0x, Core Speed at 398 MHz
Hi,
First of all I'll tell you what I'm running:
Dell Inspiron 1520 laptop
Windows 7 Ultimate x64
Intel T7250 2.0 GHz
4GB DDR2
250GB Samsung Internal HDD
My old hard drive died recently, so this morning I switched it for a brand new replacement.
Upon reinstalling Windows it was clear that the computer was running dreadfully slowly, so I downloaded CPU-Z to see what the CPU was doing. CPU-Z says that the processor is running with an apparently unchanging multiplier of 2.0 (normally between 6 and 10 depending on what SpeedStep is doing) with a bus speed of 199.45 MHz, reporting a core speed of 398 MHz. Additionally, it's reporting a Core VID of 0.85V (the Intel website says that the range for this processor is 1.075V-1.175V)
When I boot into the BIOS it reports the CPU to be running at 2 GHz, and using ThrottleStop allows me to bring it back into normal range once Windows is loaded. The computer doesn't seem to boot any slower than before, but once it gets to the logon screen it slows down, which leads me to believe that it's somewhere there that is going wrong, perhaps? I've set ThrottleStop to load at startup, but isn't a foolproof solution and, really, I'd much rather have Windows manage the CPU than have to do it manually.
A second reinstall of Windows has not solved the problem.
If anybody has come across something like this before, or has any ideas for how to begin trying to sort it out then I will be very, very grateful.
Thanks.
