Need help choosing RAM

chenc SG

I wanted to upgrade the RAM of my old desktop, and need some advices.

These is the scan result from Crucial

Each memory slot can hold DDR2 PC2-4200,DDR2 PC2-5300,DDR2 PC2-6400,DDR2 PC2-8500 with a maximum of 1GB per slot.

Can this RAM be used? (its really cheap in the IT Show)

DDR2 667MHz PC2-5400 DIMM

Or has anyone seen one that works better than the one above for my PC?

Tks

Yes.

The above ram could be used.

I don't know what's the difference between 5300 and 5400 (both are 667 MHz anyway)

But in my opinion, they should work. What is your computer specs?

That number at the end of the RAM is merely the speed. Its actually the highest speed its rated for(though some people can get more out of it).

There is no problem with running higher speed RAM in a lower speed motherboard, as long as its the same type(in this case PC2, which stands for DDR2).

It will merely reduce the RAM's speed to the maximum it will allow. If it is indeed limited to that speed, it will simply slow the RAM down to PC2-5300.

Nothing to worry about(except price, as you usually pay more for higher speeds, though in this case its minimal at best).

Tks guys.

Just not too sure because its 5400 instead of the said 5300. Think now it clears things up.

One more thing, theres this 1GB DDR2 1066Mhz PC2-8500 going for $69, $40 more expensive than the DDR2 667MHz PC2-5400 DIMM. Can my computer use this one? And is the $40 difference worthy in term of performance? I am buying 2 so thats like $80 difference

1066Mhz PC2-8500 vs DDR2 667MHz

their speeds are different.

1ghz vs 0.667ghz

yes, your com supports it. (from crucial log that u posted)

The PC2-5400 is basically the same thing as its 5300 counterpart, but it's just that it's rated to be slightly faster than a 5300.

"Some manufacturers label their DDR2 sticks as PC2-4300 instead of PC2-4200, and PC2-5400 instead of PC2-5300. At least one manufacturer has reported this reflects successful testing at a faster-than standard speed, whilst others simply use the alternate rounding as the name, as described above (in the article)."
