There was a problem filtering reviews right now. Please try again later.
I decided to get 2 additional modules of 4GB each or total of 8GB. I almost purchased the Corsair Vengeance because of its popularity. But then I read how some users had fit and clearance issues with the Vengeance due to its size. To avoid that problem, I went with these Crucial Ballistix 2x4 GB modules.
Upon opening my desktop PC tower to install the Crucial RAM sticks, I was glad that I went with these Ballistix. They are the same height as the original RAM modules, and there is not much clearance. I removed the original 2x2 GB modules (already 6 years old) and put them in the slots that have been open since purchase. Then I inserted the Ballistix in their place to have them closest to the CPU. Installation was very easy and quick. Afterward, I verified that the system now recognizes that total RAM is now 12 GB (new 8G + original 4G).
It has been two weeks since I installed the Ballistix modules. So far no more crashes. Also everything just seems much quicker than before, especially when I have multiple applications running at the same time.
Very glad I purchased this item. I should have done this sooner.
After installing the RAM, please run some randomized memory testing program. Such programs write random data to random parts of the memory and see if what is read back matches. Also, they check that writing some data to one part of the memory does not change other (nearby) parts of the memory.
While booting, pressing Esc or F9 or F12 or ... my bring up a menu containing an option like "Diagnostics", which usually has options to perform randomized testing of memory. In my case, the diagnosis found that one of the 4 sticks was misbehaving. I have attached a picture. The diagnosis also pointed out the slot where the faulty stick was plugged in. I returned all the sticks and saved myself future troubles.
If your BIOS does not have such a diagnosis option, look up memtest86. One relative disadvantage of memtest86 is that it would not directly identify the faulty stick.
Faulty RAMs are unfortunately not so uncommon. So I have five 2 stars instead of 1, assuming that I was unlucky. I wish everyone buying this product, certainly every reviewer does a randomized memory test.
I run these sticks rock-solid at DDR 2133. When I tried DDR 2400 I could boot but would freeze or restart during games (I'm too afraid to increase voltage to overclock more). My ASRock Z77 Extreme4 perfectly recognized these modules and set the correct CL, TCL, etc. timing perfectly. For my previous (but 4-5 year old) G.Skill sticks I had to manually input the timings.
I used to have a 6 DIMM slot motherboard that had 6 sticks of 2gb RAM for a total of 12 GB. My new motherboard only had 4 slots, so then I could only have 8 GB. Playing Grand Theft Auto V used up almost all of my RAM and caused the game to stutter severely (this doesn't register in frames per second as measured by Precision X or FRAPS). Upgrading to this RAM allows me to play GTAV without running out of RAM. The most mem use has been 10.1 GB.
A nice side benefit is that it reduced heat compared to my previous setup as it has half as many modules and better airflow.
Cons: There are no cons that I can see, except that my next motherboard will probably require DDR4, but I'm not upgrading for at least a couple years.
Other Thoughts: I tested these at different speeds using a TF2 benchmark, which is ideal since this old game is not tied as much to graphics. Here are the results (I tested at 2133 twice):
2639 frames 30.650 seconds 86.10 fps (11.61 ms/f) 3.462 fps variability
2639 frames 30.124 seconds 87.61 fps (11.41 ms/f) 3.637 fps variability
2639 frames 30.211 seconds 87.35 fps (11.45 ms/f) 3.618 fps variability
2639 frames 29.676 seconds 88.93 fps (11.25 ms/f) 3.794 fps variability
Again though, 2400 wasn't stable so I stick to 2133. I never tried tweaking the voltage.
So the marginal improvements in FPS based on the above are as follows:
Edit: Bought even more ram, but Chrome is still not satisfied. Must sacrifice firstborn so I can buy more ram. Joking aside, this is some very good ram. I can see lots of reviews for the 1600 mhz ddr3 Kingston for about three dollars more, but I don't understand why so many people would pay for ram that is essentially worse. This ram is made by Crucial (already a plus there) and it has basically the same specs as the Kingston ram, the difference being that this Crucial ram has lower latency than the Kingston (CAS 9 vs CAS 10). The only reason I could see people would buy the Kingston ram is because it has the barebones ram almost completely covered by the heatsink, compared to this ram, where it only partially covers the ram; In other words, for the looks.

That said, the ram has been totally reliable. Very happy with my purchase.
