I wanted to upgrade my SONY VAIO RAM Memory to make it faster but wondering what RAM is best suited for my CPU with the following details: 64Bit DDR2-667 (333Mhz DoubleData Rate with 5-5-5-15 timings)
CPU Speed: CPU Clock: 798.0 MHz (original: 2500 MHz), CPU Multiplier: 8x,
CPU FSB:Real Clock is 200 MHz (QuadData Rate) & Effective Clock:800Mhz
Memory Bus:333.3 MHz
DRAM:FSB Ratio : 10:6
Will it be alright if i will install DDR2-800Mhz (400Mhz with 5-5-5-18 timings? Is the Front Side Bus score limiting or just the minimum value and would adjust correspondingly up to effective clock limit of 800Mhz?
I look forward to your soonest reply.

Typically speaking, most OEM systems have one speed of memory that they run. Since memory is backwards compatible, you should be able to install the 800MHz parts into the system, however, chances are they would run at 667MHz. Also, the performance gain going from 667MHz memory to 800MHz memory would be very minimal. You will receive the most performance gain by adding more memory to the system if you are able to.

Hi there. If you want to get the 800 mhz ram - you might have to adjust the settings in the Bios to 400 mhz for the front side bus instead of the default 333 setting. Hope this helps you in any way.
