Hey all, Not sure if this is the right section to ask this question but I guess I'll find out. 
 
So currently I'm using a EVGA X-58 Classified 3 Motherboard and I'm using 12GB Corsair Vengeance DDR3 (3x4GB) in Tripple Channel . I'm looking to buy another 12GB of ram to hit a total of 24GB because a lot of games and programs I use are pushing my Memory at 80%+ Usage most of the time.
 
My Questions is that I've found another 3 sticks on Ebay but they differ a little bit on the specs for the Version. I'll show you the pictures 
 
This is My Ram Im currently using. 
-- 
 
Its showing Ver.5.12
 
 
Now the package I found on Ebay for bid $25 and buyout $40 + $9 shipping are these..
 
-- 
 
They are showing a Ver2.12  
 
My question is will this cause issues using 2 different versions? or does it only matter that the timings and model numbers match?
 
I've been out of the PC game for a while lol a little rusty.
 
I also have a question about timings. 
 
I'm using currently with my 3 sticks a custom Bios setting.
 
Memory Frequency - 1600Mhz/2:12
+CL 9
+RCD 9
+RP 9
+RAS 24
+RFC 88
Command Rate 2T
 
Voltage Control 
CPU VTT +100
DIMM Voltage 1.5
 
 
Will I have to changes these settings at all in bios if I just add another 3 sticks? Since Im no longer using only 3 sticks in Triple Channel?
 
Any help here would be great :D Ty!

as posted above "might work" ......
 
It is not ideal to mix any RAM especially with different Version ...  still maybe it works, even if you need to manually change timing for stability
 
see this thread:  Good Guide of the Basics, from Corsair --> RAM: How to Test RAM Modules for Memory Issues
 
----> RAM: Can I mix CORSAIR memory kits?
(excerpt / copy)

"We strongly recommend that you do NOT combine multiple kits of CORSAIR memory in your system. This is because our memory kits are only validated for their rated performance when only using the modules included in that specific kit (DIMMs sold in the same box).
If you combine multiple kits, even if they are rated with the same speed, you risk causing compatibility issues such as system stability problems, the overclock profile being prevented from enabling, or even your system being unable to boot."
 



 

the link is Corsair's official reply to this question ... "mixing any ram"
 
only Corsair would know what the Rev differences are, if that information is not proprietary, they may share it with you .... I'm guessing they will just say it is not guaranteed to work.  Maybe if you are really lucky they can help you secure a set of 6.
 
I'm just saying there are no guarantees it will work @ "factory clocks" or at all ...
 
so, do you want to take a chance?  would you be OK if it did not work?
 
I've bought two sets of RAM before to double RAM & had no issues, though they were identical including Rev number
 
(I might have to dig into my storage & see what might be lurking in my old X58 XPower rig)
