When I enable "Intel TurboMode Tech" in CMOS Setup of P55H-A V1.0, I see the CPU performance only getting a little higher. How to improve it?
Please update the BIOS to version 10/01/26 on your P55H-A V1.0. Then you will see the CPU performance is much improved on this MB after "Intel TurboMode Tech" is enabled.
Below is the link for you to download the BIOS.
System reports 8GB(3.99GB usable) at 64bit OS with 8GB(2GB*4pcs)memory installed. And "Memory Remap Feature" is "enabled" under Advance Chipset of BIOS.
Please make sure that you exact follow the instruction of the manual for plugging the memory modules in order first as defined by Intel.
The possible reasons may cause the memory size half reduction are,
1. Memory Remap Feature need to be enabled for 64bit OS.
2. Memory module not well installed on DIMM slot.
