I am looking to upgrade the RAM in my laptop, and I've researched the exact type that I need. However, I am given two compatible options of 2 GB upgrades. One is a DDR2-533 and the other is a DDR2-667. Does anyone know if one is better than the other? The price is only $5 more for the 667, so is the difference really that much more?

The number at the end represents the speed at which the RAM runs out. DDR2-667 is capable of running at 667 MHz (or less), while DDR2-533 can at 533 MHz (or less). Some motherboards only support a certain speed, so buying faster memory isn't bad - it's just wasteful.
If you're ADDING to your current memory, your motherboard MAY require that the memory be matched. If you're REPLACING your current memory, it doesn't matter.
Realistically, spend the $5 bucks for the DDR2-667 as it should work assuming everything else matches what your laptop uses.

Check the bus speed of the motherboard (call the store or manufacturer). It may or may not benefit from the higher speed, and therefore may or may not be worth the extra cost. If it's only capable of using 533 Mgz memory, then the 667 Mgz will be no benefit, but will still work.
If you don't want to bother with the hassle of finding out, then just go with the 667.

If your motherboard will support the 667, spend the extra $5. It will be worth it.

Oh for sure, if you mobo supports it, then get that. Heck, I'm still using an old mobo with SDRAM 133 mhz ram. Thats the fastest ram i can get on this mobo. So to get an extra 133Mhz for 5.00 is a steal. That would mean your memory is 6 times faster than mine, versus 5 times faster.

Clock speed = Controls the timing of documents around the equipment, a complicated technique. RAM = Random get admission to memory = Use by the equipment to shop and safeguard documents it incredibly is in use and for speedy get admission to. additionally keeps tips / documents for methods engaged on the equipment. Cache = A small quantity of memory now equipped right into a CPU used as a short-term documents shop for speedy get admission to.

Yes, pay the extra $5, your memory speed is one of the primary factors of performance. $5 for a 133 mhz difference is a very good deal.

I'd buy the same speed because the ram will only run as fast as your slowest chip. If you plan on not using the original ram then go with the faster pair.
