Well I wouldn't go solely by some customer reviews. RAM by all the major suppliers (Crucial, Corsair, etc) is all good.

Well I wouldn't go solely by some customer reviews. RAM by all the major suppliers (Crucial, Corsair, etc) is all good. Better to use RAM from the approved list suggested by the board maker Asus. This is categorically not true. Some major manufacturers, have had *major* problems with reliability. To the point they even switched chip supplier, when making the DIMMs to try to stop it. And this is why we read customer reviews, to easily gather (data mine) the knowledge that is available. If there is an obvious problem, and a lot of unhappy customers, the customer reviews form a gross filter or "early warning system". At one time, I would have sworn by Crucial Ballistix. Now, not so much. They've had their problems over the years. Which is why you check the customer reviews for "trending". Crucial had so much problems at one point, they stopped shipping Micron chips on the DIMMs, and started shipping Samsung. Just to give you some idea. Some manufacturers, are "rebranders" and don't actually make the RAM themselves. They don't actually have their own factory, churning out DIMMs. But what they do have, is a good contracting system, having the DIMMs made by third parties, tested, and then placing their own sticker on the RAM. If the contractor violates their trust relationship, they'll get turfed. Now, knowing that, imagine what the test results might mean. Sometimes, a SKU on Newegg, goes from "good" to "bad", on a lot basis. Some RAM manufacturers have changed chip source (when the "good" chips ran out), and if you're careful, you can spot the point in time that the modules became not worth buying. This tends to happen for DIMMs which extend past the official JEDEC range, and are "binned" or "made by binning" type products with elevated operating voltages. So if you were shopping for DDR3-2400, you might look for that in the customer reviews. We can't carry this "tea leaf" exercise too far. The idea is to spot trends or intelligence *if available*. For example, there was an issue at one time, with Micron D series silicon die, and a certain family of processor. To the point it might even have been mentioned on Anandtech. If you want, you can start sweeping the net (Anandtech forums, Xtremesystems.org forums) for that kind of knowledge. Using Newegg customer reviews, is an effort on my part, to make this data mining exercise less onerous. But if you *really* want to know a lot about RAM and RAM compatibility, then you'd spend the extra couple hours finding out that way. There are enthusiasts out there, who own twenty or thirty sets of RAM, and test them all. And when they spot a trend, or notice a problem with a new motherboard family, they can provide interesting input. This entry is a joke, but this is just to make a point. http://www.newegg.com/Product/Produc...82E16813131754 "3/16/2012 4:02:48 PM Awesome board! My ram wasn't on the list of compatible ram and it works fine." At one level, you select RAM based on specs. Does a motherboard family support all the RAM on the market ? DDR3 comes in "regular" or "reduced voltage" RAM. At one time, Intel supported both and AMD supported one of those. So one of your checks, would be to see whether the broadest range of RAM is supported. From the user manual for the motherboard: "DRAM Voltage[Auto] Allows you to set the DRAM voltage. The values range 1.20V to 2.20V" So that tells me the board (depending on CPU type), can support DDR3L. DDR3 nominal would be 1.5V, but there was some RAM where the voltage spec is centered at 1.35V. So it looks like that board is intended to cover both types. (The CPU actually determines whether the support is there, but tracking this down now on the AMD site, would be next to impossible.) You do the best you can, to data mine before buying. It could still happen, that you get a dud, or mismatch between your board and the RAM purchase. The purpose of JEDEC standards, is to try to make this process as painless as possible (broadest compatibility), which is why you don't absolutely need to use the Asus memory compatibility chart. But it makes some people feel better. When I clicked the download link for M5A99X Evo memory chart (from support.asus.com), this is the URL of the download. It would appear they just copied the test results, from another motherboard. http://dlcdnet.asus.com/pub/ASUS/mb/...Memory_QVL.zip To give another example of a "detected trend", when 2GB modules first came out, the BIOS simply wasn't set up on any board to properly handle them. The 1GB modules might work fine for you, while the 2GB, you could try all the tuning parameters on the board, and not get the RAM stable. I have a motherboard here, with that problem (that machine still has only 1GB modules in it). As BIOS updates were handed out, this problem gradually disappeared. And that observation, at the time, would have influenced a RAM purchase (i.e. you would buy 4x1GB instead of 2x2GB, until they fixed that). If you *didn't* read the enthusiast tea leaves at the time, you would have missed that, and ended up with lots of crashing misery. The Newegg's of the world, didn't stop selling 2GB modules, while the problem existed. It was eventually resolved, but in fact, not on my motherboard :-( The 2GB modules are now in my current machine, where they work fine. Paul |

The major suppliers such as Crucial and Corsair all make and/or sell very good quality memory in general.... all manufacturers and suppliers have problems because this isn't a perfect world. It would be like saying all the motherboard makers are not good because at one time they used the defective capacitors that were going around. What I stated was that going SOLELY by customer reviews was not a good idea. I agree that they can be used as a filter... most of us probably do that, but you have to be very discerning, as many people will report problems that are actually due to their handling or configuration. -- Glen Ventura MS MVP Oct. 2002 - Sept. 2009 CompTIA A+ |

Are these models okay or not? What is the difference between the two models above? And, how is G.SKILL vs Crucial vs Corsair? Corsair, G.Skill, Geil, Patriot, Mushkin, OCZ, Kingston are nothing special. Most of those companies (actually probably all but one of them) don't even test their products extensively but simply use PC- based testers, rather than the million-dollar machines that chip manufacturers use. One of those module companies even said it was OK for a module to show 2 errors during testing (except for their 2133 MHz/PC17000 modules, which had to show 0 errors). Crucial is always good as long as you avoid anything with heatsinks on it. Another brand that's always good is Samsung, and their 1.35V DDR3 modules will work in 1.5V motherboards. In general you should avoid any memory with heatsinks on it because they don't help at all and are actually a sign of low quality -- the manufacturer can hide no-name or overclocked chips under the heatsinks, and it's cheaper to slap on highly decorated heatsinks than to use better quality or faster chips. Also before buying modules with tall heatsinks, check the clearance between the DIMMs and the CPU heatsink. That's not to say everything without heatsinks is high quality. It's necessary to check the individual chips, and you want chips where the chip maker or their part number is clearly visible. Chip makers include Samsung/SEC, Elpida/RexChip, ProMOS, Hynix, Micron, Nanya/ Inotera, and PowerChip. As for RipJaws specifically, APHnetworks reviewed a PC17000 model (2133 MHz) and found it was made with Hynix H5TQ2G83BFR-H9C chips. "H9C" means 1333 MHz: http://aphnetworks.com/reviews/g_ski...8gbxld_2x4gb/2 I don't think G.Skill is worse in this respect than the vast majority of its competitors, but the use of overclocked chips could explain why plain-looking, no-heatsink Samsung PC12800 modules (1600 MHz) are so well known for being able to run faster than many heatsinked modules that are "rated" for 2133 MHz. |

How can you say all the majors are all good when almost all of them sell modules with overclocked or overvolted chips that were tested at no more than 58 Celcius (many at just room temp), or way below the common 85C spec for DDR3? Better to use RAM from the approved list suggested by the board maker Asus. The approved list indicates only compatibility, not quality. |
