The Pista (Vista) experience score is based on the lowest rated component. Normally this is the memory in your system. You’ll hear many times “buy the lowest memory available from Alienware and upgrade from newegg for much cheaper.” While very true, you getting really crappy RAM that way…
Which component is scoring so low?
But yes, out of the box the m15x does a lot of downclocking and just about everything can be fixed.
1.Check this out
It will remove the powernow downclocking of your GPU, but its really not needed unless you're overlclocking or you’re having graphic issues in a specific app.
2.(I think this is your problem) out of the box the m15x will auto downclock your CPU and increase the speed by demand. I’ve done tons of test and the dynamic adjustment works really well. Basically with Pista power profile of “max performance” the CPU will idle at ½ speed, but as soon as there is a demand on the CPU it bumps it up to 100%. Even still AW has fixed this. Check out your AW hive,
download and install the x34 BIOS release for m15x. after you flash your BIOS the Pista (and XP) max performance setting will keep the CPU at max speed all the time (like it really should have in the first place). the system will be ideling during the pista experience test, so you need to apply this to get a true score
3.Buy low latency RAM for your notebook, not newegg. i.e. CAS 4 latency memory
On battery is a different story... check out my review of the m15x
to see how to keep the CPU from 1/2 downclocking on battery. But there is no fix for the GPU downclocking on battery
PS: upgrade to XP
