So I want to upgrade my PC's memory to 8gb for gaming purposes. Currently my PC has a Kingston 4gb 1333mhz RAM. Here's the exact model:

Apparently, these kinds of RAM are already phasing out and I couldn't find the same RAM and instead found this Ramaxel brand:
https://www.newegg.com/Product/Product.aspx?Item=N82E16820799001

I checked and it seems that all of the specs are the same except the physical size of the RAM wherein the Ramaxel is twice bigger.

Would it be ok to use these two together?
Also, my motherboard can only support 1066mhz and 1333mhz so i cant really buy the higher mhz of RAM, else ill have to buy a new motherboard which i'm trying not to, dont have the budget right now. Here's my motherboard just in case:

Solution
Both are close in factors as frequency, voltage and Cas latency so chances are pretty good but are never 100%. DDR3 is forgiving that way unlike DDR2 and earlier.
