If my laptop uses SO DIMM 200 DDR2 667MHz, can I put 800Mhz RAM in it?

So my old laptop is in need of a RAM upgrade. It's plenty fine for what I use that particular machine for, but the lack of RAM makes it lock up contantly, and it gets annoying, and I find myself having to reboot. I'm also gonna put Linux on it, most likely the new Zorin.

Anyway, it has SODIMM 200 pin DDR2 667mhz (or whatever the exact spec is). So looking up replacements, I'm seeing the same type of RAM, but at 800mhz. I'm going from 2x1GB to 2x2GB. But as long as it's the proper 200 Pin DDR2, I'm fine, right?

I did build my own custom rig, and RAM was one of the more confusing things to really decide on, balancing frequency with latency, although most benchmarks show they kind of even out it would seem. But is it like this on laptops as well? Will that 800mhz ram work to replace the current 667mhz? And I guess the latency may be more with the higher frequency? Or would that not be optimal?

This is the specific RAM I'm looking to get.

Thanks so much. I hope my post/question wasn't too confusing.

The answer is probably. Most systems can, or at least they will down clock the ram without trouble. There are those occasional exceptions though.

As long as ECC/non, same CL rating, it should work, but the sure way is consult with the laptop vendor/forum.

I ended up finding this kit, which is the same frequency, so that's out of the way. I'd imagine the CL is the same as the RAM I already have, since the other sticks had higher frequency and higher latency... I was only going with the other one, not realizing they had the 667 for about the same price. The other kits at the same frequency were more like $50...

Honestly, it seems like all the 667Mhz RAM I'm looking at is CL5, so I assume it's compatible, so I'll likely just try it out.

The only other thing I was iffy on, was a replacement HDD or SSD. I don't think that old thing is worth the upgrade to an SSD, so I'm thinking of doing an SSHD. I also can't find a measurement of the drive online, so I guess I'll have to pop it out myself and measure the thing. 😛
