I cannot get the AMD Processor driver to install, to improve on my quad core usage.
I have a ECS GeForce6100PM-m2 V2. (AM2) Quad core Phenom 9750.
All 4 cores seem to be OK, Prime95 will run them all 4 @ 100%.
But when running CPU intensive operations (that I assume are not designed to use multi cores)
eg. WinXDVD Ripper ( I have tried other video intensive programs & get similar results)
On its own it will run overall @ under 50% (v.roughly cores @ 35%,10%,10%,5%)
If then at the Same Time I rip a CD or load numerous other programs the overall CPU still stays around 50-60%.
The system does not seem too slow but I am sure before when loading lots of stuff the CPU load will get to 100%. Not the sort of thing I use to monitor but fairly positive when I got the new CPU some months ago it would load to 100%.
Anyway, I am guessing this is not right because I first noticed it when I did a windows update and tried to load the: - Advanced Micro Devices - Other Hardware - AMD Processor Date last published: 2/21/2008
it says "failed to to install".
Tried version direct from AMD www & ECS's own version, all fail.
Tried in safe mode, "uninstalling" from the device manager the MS own 2004 driver etc etc.
Cool & Quiet is enabled in the BIOS, but I don't understand much else of the BIOS settings
Noticed problem on previous BIOS & so installed Lastest BIOS but no better.
Add/Removed all NVidia driver full suite (leaving graphics) and re-installed a few times,

I am fairly sure I have seen my CPU usage get close to 100% when lots of things are going on.
Encoding video is very CPU intensive & ripping, encoding to MP3 a CD quite power hungry & then loading word & excel all at the same time surely should bring CPU to 80%+ or even 100%.
There are delays while these things happen, the Video encoding slows down, I know a lot is down to loading from hard drive that simply can't keep up but seems a little pointless if the CPU only ever works at half speed.
Also the AMD driver will not install so something is wrong here, whether it would help or not.
The driver must have some effect.
So you saw the update in Windows Update but you don't think it installed correctly and may have corrupted your processor performance somehow but it runs Prime95 OK?
I have looked around and it seems this update was released by AMD to better balance CPU usage in dual core processors in Windows XP so that one core wasn't running at 100% and the other idle when a system's cores could have been running at 50%:50%. Don't know if it included quad cores.
However, there is also a utility called the Dual-core optimiser released by AMD that improved timings in games and applications, not a core load balancer. Don't know which driver/utility the update you downloaded was.
