Review: One of the top brands didn't fail in delivering. - Fast, stable, reliable, durable, you can't beat what you get in this ram. I have pushed this with hungry software and it stands up like a champ and screams "give me more!". Easy to install like any other memory card, just slide and clip them in. You just can't beat Corsair. Well worth the value!
Review: 16 G memory upgrade Dell xps8300 - Corsair XMS3 16GB (2x8GB) DDR3 1333 MHz (PC3 10666) Desktop Memory 1.5V I 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 GHz 64 bit Windows 7 Ultimate SP1 Graphics card nVidia GEForce GT 530

### ⭐⭐⭐⭐⭐ 16 G memory upgrade Dell xps8300

### ⭐⭐⭐⭐⭐ Been buying Corsair memory for awhile, loving it more than Kingston
*by B***W on November 19, 2012*

I've preferred Kingston for years when it comes to memory, but lately I've been going with Corsair. Same, if not better specs, than similarly priced Kingston products, and the same warranty. Lifetime warranties are a must whenever you can get them in the electronics world, ESPECIALLY with memory. Will memory fail you? At some point, yes. I have about 1 stick of RAM die every 3 years, with constant use. The XMS lineup has performed extremely well with simple setups as well as heavily overclocked setups of mine, which run liquid cooling. For the price, you can't go wrong--seriously. This particular stick, 1x4GB, is in an HTPC system running XP3. I've used their other sticks as well, 2x4, 4x8, etc. AWesome stuff. PROS: * Price - excellent price point, the same or better than Kingston * Performance - For the price, it's outstanding * Longevity - This stuff is as strong as a horse * Warranty - It's lifetime, hands-down that's awesome TECH TIP: You can almost always buy memory which is rated for a higher speed than what your motherboard or CPU uses. For instance, if your motherboard/CPU says it uses 1333mhz DDR3, you can use 1600mhz in almost every single situation. It'll simply clock down to the lower speeds. There's a slight advantage to doing this also, it allows you to run more aggressive timing when doing extreme overclocking. Remember, your mileage may vary, and "almost always" doesn't mean "always".
