Hello,
I am upgrading gaming PC and I am not sure how to handle RAMs.

I have Kingston:
1x 4 GB 1333MHz CL9 ( http://www.kingston.com/dataSheets/KHX13C9B1R_4.pdf )
and
2x2GB 1600MHZ CL9 ( khx1600c9d3bk2/4g, http://www.kingston.com/en/memory/search/default.aspx?d... )

That is not good right? I failed long ago when buying extra 4 GB..

Is it slowing 1600 MHz to 1333 MHz? And I am not sure about CL9, one is 9-9-9 at 1.5V and older 2x2GB is 9-9-9-27 and 1.7 - 1.9V..

Can I buy another one to work with these? Keep one, and upgrade with similar, or just best will be buy brand new ones?

I will apreciate any suggestions and advices :)

the best is of course is to buy a brand new kit like 2x4GB or 2x8GB (depends how much you want)

You can mix RAM as you done, when you mix a 1333MHz and 1600MHz the BIOS will downclock the 1600MHz to 1333MHz as you say.
I dont know how much the different latency will effect the performance, but have different voltage can be tricky.

So getting a new RAM kit with the amount of RAM you need/want is the best or upgrade your current RAM with a 2nd kit with the same type of RAM. (brand, latency and voltage)

And as Samat said, check MoBo for speed compatibility.

Thanks for quick answers guys,
I am thinking 16 GB, beacuse i am upgrading my PC a lot, so wanna do it all, so it will last few years.
I wanted to save some money on RAM. I checked, and it seems they are selling some new version, not exactly same RAMs.So to have a piece of mind, I will just buy new ones, and try sell old parts.

Probably some 2x8GB 1600MHz+ CL9 is best for gaming?



RAM: ?
MB: ASUS M5A97 R2.0 (wanna buy some Z97 MB)
CPU: AMD FX-6300 + XIGMATEK Loki II (wanna buy i5-4690K)
GPU: MSI GTX 970 GAMING 4G (replaced GIGABYTE Radeon 779OC-2GD)
PSU: EVGA SuperNOVA 750 G2 (replaced LC POWER LC550-550W/PFC)
