Basically it states that Each memory slot can hold DDR2 PC2-4200 with a maximum of 1GB per slot. However, currently installed memory is DDR PC2-5300 (I also confirmed this by pulling one of the sticks out personally)
I plan on buying a set of 2 RAM modules at 1gig each.
My question is, do I get DDR2 PC2-4200 • CL=4 • Unbuffered • NON-ECC • DDR2-533 • 1.8V •
The only difference that I can see is CL5 on the PC2-5300, but it's DDR2-667. The PC2-4200 has CL4 but is DDR2-533.
I know the difference is probly minimal, but I want to squeeze every last drop of performance out of it, so thus my dilemma.
What confuses me is that the laptop currently has PC2-5300, yet it has the slower CL of 5. My laptop has a Front Side Bus of only 533 MHz, so it isn't taking advantage of the 667MHz that the PC2-5300 memory has.
From what I can gather, the PC2-4200 has a CL of 4, and is 533MHz.
So given the fact my FSB on my laptop is only 533MHz to begin with, would it make sense to get the PC2-4200 over the PC2-5300 just for the better CL, because both will run at 533MHz anyway, ? or am I way off?
Your laptop has an older chipset on the motherboard; it runs at a slow speed. You can use either speed of memory; Fry's.com and newegg are pretty cheap, and the Fry's stores locations are rock bottom when on sale. I usually buy crucial or corsair. Before changing, you can run cpuid, a free download, and see what timings it detects.
