Not sure this is the right subforum for this but here goes...

Is there any harm in mixing RAM by the same manufacturer (G.Skill) with slightly different RAM timing specs?

I have 8gb worth of G.Skill Ripjaws X currently with the 9-9-9-24 timing. Newegg has 8gb of G.Skill Ripjaws (not the X line) currently on sale with a timing of 9-9-9-24-2N. Any danger of instability or anything else from mixing the two in my system?

My current RAM:

http://www.newegg.co...N82E16820231428

• DDR3 1600 (PC3 12800)
  
• Timing 9-9-9-24
  
• Cas Latency 9
  
• Voltage 1.5V

The RAM I'm looking to add to the existing RAM:

http://www.newegg.co...N82E16820231314

• DDR3 1600 (PC3 12800)
  
• Timing 9-9-9-24-2N
  
• Cas Latency 9
  
• Voltage 1.5V

the last number is the command rate which isn't displayed on all packaging mostly because its only a minor factor.

they "should" work fine together.

Those have the same timings. The 2N at the end is the command rate, and in all likelihood you'll be using 2N in the first set anyways. Either way both will work at 2N, as will any other DDR3 in existence. That combination of RAM will mix and match just fine. Having four sticks will stress your memory controller a little more, but it's not as though it's going to cause any actual problems.

Edit: DV beat me to it

Beat you to saying it! Oh wait, crap.

DV McKenna and Catamount got it right.

I have two different sets of G.Skill Ripjaws myself (those 2x 4GB GBRL you already linked and 2x 2GB GBRL) and they work fine together. I see no reason why it shouldn't be the same for your two sets. Though my system keeps telling me that those are 1333 RAM and I have to adjust them manually to their real specs.

Thanks to DV McKenna and Catamount for the quick replies. It's what I figured but I wanted some internet confirmation.

What do you mean by manually adjusting them to their real specs? How do you do this? BIOS?

Yes, the BIOS/UEFI settings. The timings are correctly recognized, but for some reason both of my sets are set as 1333 MHz RAM and I had to adjust them manually.

If you are unsure how to do it, or being afraid to break something, don't bother. The performance difference isn't really noticable for most applications. Just install them and boot your system normaly. You really should have no problems.
