Latest Bios
Memory remapping enabled
Check MSCONFIG max memory isn't limited.
I noticed that on EVGAs performance tool the memory is reading as single channel when it should read dual channel.
I'm using a Radeon HD 4890 1GB DDR5
OCZ Low Voltage Platinum PC-10666 Dual Channel 2GBx2 DIMMS
I've been scouring the internet in search of some sort of answer. Please Help!
Force windows 7 to set memory at
5997 to 8143 as you have to set at x1,5 the amount of 4Gb Ram aviable,
In the System Properties tab=> Avanced System Parameters tab=>Performances=>Modidy...
Don't let automatic setting. Don't use any LargeSystemCache in the registry
Anyway, on 4095 ram only 3998 are there, 97 ram amount are reserved for Hardware purpose.
