Corsair Memory CMX8GX3M2A1600C9 XMS3 8GB (2x4GB) DDR3 1600 MHz (PC3 12800) Desktop Memory 1.65V

Well there's not much I can say. umm it works and it's memory that works. If you are thinking of going with triple channel memory with the i7 series then this is what you want. Also the price is unbeatable. I've overclocked my CPU and these memory modules still run with insane speeds. I'm using a Asus Sabertooth X58. No problems found here. However if you aren't seeing all 6GBs of memory in the BIOS I suggest reseating the RAM sticks. I had to reset my RAM about 3 times and I'm never removing them again lol. I've been using this RAM for about a month in a half with no problems thus far. This RAM is very good for overlocking as well and very flexible for different BIOS settings. Also I'm loving the heat shields Corsair provided, that's just a big plus.The ram is so good and so reasonably priced I'm thinking about buying another set just so I can say I have 12GBs of RAM. Well honestly I use alot of RAM eating programs. Like music programs and video editing etc. If you are a casual user or a gamer you will only need one set of these RAM triple channel kits.

I installed four (two pairs) of these DDR3 memory modules in one of my home-built computers (for a total of 8 GB). They have operated flawlessly for two years.For the 8 GB kit, see: Corsair XMS3 8 GB (2 x 4GB) 1333 MHz PC3-10666 240-Pin DDR3 Memory Kit CMX8GX3M2A1333C9.Make sure and certain your computer's motherboard uses DDR3 memory. Before you order memory modules, you should review the webpage and "User Guide" for your motherboard. For example, the ASUS website provides a “Qualified Vendor Lists” (QVL) of compatible memory for the motherboard I used in this build. Your motherboard's vendor may have a similar list. If you purchased a ready-built computer, then look on the manufacturer's website to verify that you are purchasing the correct memory, or give them a call.My computer's motherboard requires DDR3 dual in-line memory modules (DIMMs), installed in "matched sets" for "dual channel" function. My motherboard's "User Guide" recommends installing DIMMs from the same vendor, with the same CAS latency, and of the same version or date code (D/C). Therefore, it may be best to install all memory at once (in the initial build) instead of waiting to add more memory at some future date (although I have never had a problem doing that).Please note: If you are only installing two DIMMS, you may need to install them in only two specific slots on the mother board (i.e., you can't just install them in any two slots). Check the "User Guide" for your motherboard to ensure that you are inserting the DIMMs in the correct slots. Since I filled all four memory slots on the motherboard this was not a concern for me.No matter how much physical memory you install, your copy of the Windows operating system may limit how much memory your computer can use. The 32 bit versions of Windows can only address a maximum of 4 GB of memory, with only (about) 3.5 GB of that usable. Windows 7 or Windows Vista Home Premium can only use 16 GB; Windows 7 or Windows Vista Home Basic can only use 8 GB. Memory limits are not an issue with later versions of Windows.I recommend that you run a memory test on your newly-installed memory. I used Memtest86+ (it's free). Extract the image (iso) file from the ZIP file, and then create a bootable CD by burning disc from image (do NOT copy the iso file to CD, burn disc from image). I ran this memory test prior to loading the operating system.

Corsair XMS3 16GB (2x8GB) DDR3 1333 MHz (PC3 10666) Desktop Memory 1.5VI ordered these to upgrade a Dell xps8300 desktop computer from 8G to 16G. The factory-installed memory was in the form of four 2GB modules (one in each of the available memory slots). This product consists of two 8GB modules, so there is still room to expand to 32GB total, although the system only recognizes 16G without some tweaking. Based on the instructions that came with the memory kit and the Dell users manual, the modules need to go into the slots marked 1 and 2 (not contiguous but easily identified by number '1' and '2' and also the fact that these two slots have white latches versus black for the other two). The last of the attached pictures shows the layout. Removing the old units was easy once they were exposed. The main detail is to move the spaghetti of power cables out of the way to get a clear handle on them. Just press down on the two latches per slot and the modules slipped out without requiring any force. Likewise the new modules slipped in easily and lifting up on the latches while holding the card down worked smoothly.After turning on the power, everything booted up as usual without issue. Checking the installed memory via System information, it showed 16GB installed memory. I also ran Dell diagnostics to check everything and everything passed.I've only had them installed for a couple of weeks so I can't rate the durability (other reviewers have noted failure after months of use) but for value and apparent quality, I gave it 5 stars.Did it make a difference? Well it didn't hurt :) The performance rating from the System dialog (for what it may be worth) didn't change much between before and after the upgrade. But I think I can say it did speed up loading Shadow of the Tomb Raider game on Steam slightly, though not much difference in actual game play. The biggest factor there is probably the graphics card, and that's another jump up in $$$.System:Dell xps8300 (Aug 2011)Intel Core i7-2600 @3.4 GHz64 bit Windows 7 Ultimate SP1Graphics card nVidia GEForce GT 530
