Is it ok to mix these two RAM?

[pumpkinz]

Here's the info from PC Wizard scan.

I have 1g of unknown speed
and 2g of 800hz I just bought.

I didn't realize that the RAM speed will take the slowest one.

I just want to know if it is ok to mix these two.

Thanks for your help!

You should be able to mix them, but it all depends on the machine your putting them into as some are picky about the memory they like. However as said your new ram will slow down to 667mhz instead of running at 800mhz.
