Ballistix Sport 4GB DDR3L 1600 (PC3L 12800) Low Profile Desktop Memory Model BLS4G3D1609ES2LX0

Pros: Got Good deal on mine in Feb 2013 $22.99 on sale

Cons: Now costs $37

Overall Review: Good Good

Pros: This RAM is inexpensive.

Cons: I bought two of these sticks to use with my ASRock 970 Extreme4. One arrived DOA (I RMA'd it and will receive the replacement soon), the other has been running okay. However, after many hours of troubleshooting (and even replacing my motherboard and PSU thinking that they were the problem) I was still encountering system restarts with no blue screen when the machine was performing heavy tasks (specifically gaming). I went into BIOS and manually changed the setting from 1.35v to 1.5v and now my machine is having no trouble. Other users here have found the same setting solves their problem - if you're not having luck, try manually setting the power to these sticks to 1.5v in BIOS.

Overall Review: My motherboard is 1.35v compatible but this RAM performs much better at 1.5v (which is the industry standard anyway). Set it at 1.5v and hope you don't get a DOA stick.

If you can get away with it and not get delivered a DOA stick and if know enough about BIOS to set these guys to run at 1.5v then it could be worth a buy due to the price.

I just hope this review saves you all the time I spent trying to figure out this problem. Good luck!
