Can I run these together?

[Kelieve]

Hello all. I have been trying to add more RAM to my computer. Currently I have a hynix 2GB DDR2 800 PC6400, and I was wondering if I could run my computer with another stick Apacer 2GB PC26400 CL5.
Thanks.

Not 100% sure, but honestly ram is not overly pricey anymore and would be better off getting a set. They like to give you fits if they are not the same

Where are you shopping at?

As stated above, getting a match set would be smartest. However if they are free/really cheap they should work, but run at the slowest of the 2.

Ok, I tried them and they seem to work fine. They are supposedly both 800mhz and 2GB. Yet I encountered a little problem. The startup details (usually that shows the processor things) won't show up. I will have to recheck though. THanks.

Oh.. yha what will change is the CL 5 timings. Which is another measure of the ram speed. 800 (5 5 5 12) vs 800 (7 7 7 18)

5 is faster than 7

And which one of those two are faster? I would like to know the brand, and I tried running them together, and havock was created . THanks for your help so far.

The one with the lower CL NUMER WILL be faster.

When you say it created havoc, what happened?

Most of the time some programs would shut down, but it got to a point where I could not turn on my computer. I removed one of the sticks and it worked fine, so that is a problem solved. Would it create problems if I were to run two of the exact same sticks?
Thanks.

EDIT: How can I check the CL number?
EDIT 2: Ok, I checked the timings and one is CL6 at 400mhz, and the other is CL5 at 400mhz. I tried running both, and the CL5 seems to run faster while booting, but during startup the CL6 is a bit faster... weird? Was this the reason why havoc was created? If I run two of those CL5, would it run fine without any problems? Thanks.

Hmm, sounds weird. No the timings won't cause muck ups.

Do you have them in the correct slots? Wht mobo do you have?

It is an Elitegroup A740GM-M.
