What is the difference between these two memory kits (they look the same and they're the same price) and are they compatible with the ASRock 4COREDUAL-VSTA. The Memory Configuror only lists DDR's and I want to be sure about DDR2's before purchase.


Thanks in advance for any help.

There is no difference in the memory, only the color of the heat spreader , the PT version is platinum in color.



can u tell if these two are compatible? the configurator does not list any DDR2 ram for this motherboard ASRock 4COREDUAL-VSTA and Corsair DIMM 2048MB DDR II 675MHz XMS2 Twin2X2048-5400C4 dual channel kit or CORSAIR 2 x 1GB 800Mhz 5-5-5-12 XMS2-6400 ver5.2


Very Thanks :cool:

I think that MB does not give you the voltage options in the BIOS and I would suggest VS2GBKit667D2 for that MB.


Very thanks



Bios setup:


DRAM Voltage

Use this to select among [Auto], [High], [Normal] and [Low] for DRAM Voltage.

The default value is [Auto].


Per request ...the following are the Voltages on the Asrock 775 VSTA Board: forum.anandtech


DDR2 "high" 2.0v

DDR2 "norm" 1.9v

DDR2 "low" 1.8v



4COREDUAL-VSTA dram voltage support asrock


DDR2 "high" 2.03v

DDR2 "norm" 1.93v

DDR2 "low" 1.83v



I will try these memory Twin2X2048-5400C4 and make an answer :idea:

I too want to use TWIN2X2048-5400C4 (2 x 1024 MB Dual Ram ddr II PC2-5400) in my AsRock 4CoreDual-VSTA. They are the same price as Value sticks.

This shouldn't be a problem, right?

Too bad the poster didn't return with his experiences.

If you have the option to set the memory Voltage to 2.0 Volts then they should work but as I said before I do not think that MB will let you set the memory Voltage. I would suggest using our Value Select on their MB's only!
