Help picking out more memory modules

I need help picking out 2 more ram modules. This is my first time doing this.
My computer: cpu Intel Core i5-3570 Ivy Bridge 22nm,
motherboard Gigabyte Z77M-D3H-MVP 4 DIMM slots
ram modules Kensington 8GB (2x4GB) DDR3 1600 Dual Channel kit

I ran the program CPU-Z and it says the following under Memory:
Type DDR3 Size 8192 MBytes Channel# Dual
DRAM Frequency 800.8 MHz FSB:D RAM 1:6
Cas# Latency (CL) 9.0 clocks
tRCD 9 clocks
tRP 9 clocks
tRAS 27 clocks
Command Rate (CR) 1T

CPU-Z under SPD
Slot#1 DDR3 Module Size 4096 MBytes
Max Bandwidth PC3-10700(667 MHz)
Manufacturer Kensington
Part Number KHX1600C9D3/4GX
SPD Ext. XMP 1.3

Slot#2 empty
Slot#3 same as slot 1
Slot#4 empty

Now I want to get 2 more 4GB modules same as above to fill slots 2&4 to make a total of 16GB. But I cannot find my present Kensington KHX160C9D3/4GX modules on the internet.

What I did find were Kensington 8GB (2x4GB) DDR3 1600 PC3 12800 KHX1600C9D3K2/8GX 1.65v CL 9 Dual Channel kit
http://www.newegg.ca/Product/Product.aspx?Item=N82E1682...

My question is, will those modules that I found above work with my present ram modules? If I buy them and do the install, will things work smoothly? I did learn today how to access the BIOS, I didn't change anything, but just looked and then exit. I did notice Memory in the bios was set to AUTO

Yes, the memory is compatible and it should work with your present memory modules. I cannot assure that this will work out smoothly but yeah theoretically it should go smooth. The newer DDR3 with tighter timings can cause stability issues even if you mixing the same brand and same part number memory, not all the time but sometimes it does give you some issues.

It seems both the memory kits are almost identical and hence I see why you shouldn't try them. IMO, 2 x 8GB is better than 4 x 4GB setup. If you are willing to sell the 4GB modules or use in other system then maybe it is better to stick with 2 x 8GB. This setup runs with ease and causes no stress to the memory controller but it is the other way around with the 4 x 4GB but both setups are good. Anyways, you can decide on that.

Keep us posted!! Cheers!

I will have a look around on newegg and see about some 2x8GB modules, maybe that is the way to go

Help.. I did some searching on newegg and see 2x8GB modules, with some Cas Latency 9, some 10, some 11, also Voltage, some 1.5v 1.6 and 1.65v, which ones do I get?

RAM voltage - Anything below 1.65v is good. But I would stick with 1.5v or 1.35v

Latency: It depends on the memory frequency you are opting for. Suppose you go with 1866MHz then CL9 is the best bet as the memory runs stably with this latency any below you wouldn't want to try for this frequency. If the memory frequency is 1600MHz then CL7 is the best option.

Always try to get highest frequency memory and the lowest latency for the corresponding speed. Lower the CL better the performance.

I found my memory modules to get, Kensington KHX16C9X3K2/16X 16GB (2x8GB) DDR3 1600 240 Pin DIMM 1.5v 9-9-9
