I bought a pre built PC which came with one 8GB stick of Kingston ram installed.
At present I have a 4gb stick of a different brand installed with it, but would like to change it for a better matched stick to make 2 x 8GB.
I'm not sure what cl ram I need.
Here is a shot of CPU-Z that shows the Kingston ram on the right, and total ram on the left.
Where can I find a near match online?
I already did the Crucial scan, and Kingston search, but they both just give upgrades specific to the motherboard. Both offer CL 9,10,and 11. So I still need to know if any one can tell by my CPU-Z screen shot what CL rating my Kingston stick is so I can buy just one stick to go with it.
Thanks Bris, exactly the answer I wanted.
As for little improvement I take your point. But.
I have 2 different pairs, manufacturer wise, and size wise, as it only came with the Kingston stick unbeknown to me. I have googled a bit, and lots of posters say that with 2 different size modules it will only run in dual channen mode. Not sure if that's true as I have had no problems doing this in the past. Also CPU-Z says dual channel so I take it it's running in that mode.
Also Battlefield 4 requires at least 8GB of ram , and as my son want's my other stick due to incompatabilty with his new board I thought it's time to upgrade.
The ram is running at 666.1MHz as the 1333 stick is forcing the Kingston 800.0MHz PC3-12800 ram to run at the slower speed.
In light of the Kingston stick being PC3-12800 do you still think that the image on the left still suggests it's CL9?
As far as I know CL9 refers to the CAS latency. As the speed is increased the CAS latency is increased to maintain stability so you will probably find that PC3-12800 sticks have a CAS latency of 11 ( have not checked).
You can run PC3-12800 with a CAS latency of 9 but you are then into overclocking territory - best avoided if you want to maintain stability.
Its always better to buy modules in matched pairs and install each pair in alternate (same coloured slots), also bear in mind that if you mix modules of differing speeds then it will run at the slowest.
