G.SKILL Ripjaws X Series 16GB (2 x 8GB) 240-Pin DDR3 SDRAM DDR3 1866 (PC3 14900) Desktop Memory Model F3-14900CL10D-16GBXL

Pros: I have been running this RAM kit for about a year now. I ran Memtest86+ for two passes with no errors either. The black PCB and red heatsink match perfectly with the color scheme of my ASUS ROG MB. When I initially installed the RAM it ran at its non-OC (JEDEC) speed and timings out of the box. I selected XMP in the BIOS and everything automatically set to the OC specs of 10-11-10-30, 2N, 1.5V, DDR3 1866. One of the lowest priced 2 x 8GB DDR3 1866 kits available.

Cons: The timings are among the slowest for this type of a RAM kit. G.Skill does not guarantee two kits of RAM to work together. So if you are hoping to use two of these kits on a MB that supports 4 x 8GB RAM, you may need to buy a single 4 x 8GB kit instead. If you have a large CPU heatsink or fan that extends over the RAM slots, you could run into clearance issues with this RAM's heatsinks. In the somewhat recent past I have contacted G.Skill's tech support about other products. Their tech support was among the worst I have spoken to among the several RAM manufactures that I have used. It would alleviate so much confusion for buyer's who don't know how OC'd RAM works if manufacturers would start listing how OC'd RAM works on the packaging and in the details. This is something all RAM manufacturers are guilty of.

Overall Review: For those who don't know how OC'd RAM works. It is usually set to run at JEDEC (non-OC) speed out of the box. You usually have to go into the BIOS and manually set the bandwidth, timings, voltage, and command rate, or select XMP (if you have a MB and RAM that both support XMP) to get it to run at the advertised OC'd speed. If you are not familiar with setting up OC'd RAM call the manufacturer. Many OC'd RAM sets have less than five egg ratings from system builders who don't understand that OC'd RAM usually needs to be setup in the BIOS.

Pros: They work well, and stable. I bought these for a new computer I was building, and wanted 16 gigs with 2 sticks. They perform well and look good doing it! I am using a gigabyte UD-3 mobo with these sticks. Mobo bios default is 1333 with these installed, had to turn them up for the true 1866 from the mobo bios and they are still stable and temps low. I use these for gaming and casual use. I wanted reliable ram and that is what I got.

Cons: no cons so far. I have owned them for 6 months and no problems.

Overall Review: When I build a new computer I wait for the best sales on quality items. These went on sale and I jumped on it. I would recommend these to anyone for casual to gaming.

Pros: Never received a dead stick, works great in most use cases.

Cons: I have not managed to find a stable profile for this DIMM to run 32GB (4x8GB) at 1866 in line with a FX-8370 on a FX990 chip set. I have, multiple times, successfully managed to run 16GB (both 2x8GB and 4x4GB) of the Ripjaw X-series at 1866 with the above specs.

Overall Review: Though I am disappointed with the failure to hit the 1866 with the larger capacity, the user experience difference between 1600 and 1866 is negligible. Also, this particular DIM is not listed on the approved ram on any of my motherboards at 1866 speeds, thus I do not feel "deceived", so only losses one egg in my book. Conclusion: good sticks, though I realize we are transitioning to the new standard of DDR4. Currently running this model on the following set ups: 32GB (4x8GB) @ 1600 on ASUS Sabertooth 990fx r1 with FX-8370 32GB (4x8GB) @ 1600 on MSI 990FXA-GD80 v2 with FX-6300

Pros: Works well at 1866.

Cons: Memory description should make it clear to buyers that 1866 MHz is only achievable with motherboards that explicitly support XMP. This is true for all 1866 and above memories - not just G.SKILLs - but since it's a surprise to many buyers, this should be explicitly stated.

Overall Review: Make sure you understand XMP memory and make sure your BIOS supports it. By default your BIOS will likely set the memory at 1333MHz speed until you enable the Intel XMP settings in your BIOS, which many Intel *and* AMD motherboards support. Once enabled, you should be able to select 1 of the 2 profile configurations provided - these are read by the BIOS from the RAM itself - and reboot with 1866MHz. That *should* be all that is necessary, but it could get more involved. My motherboard, an MSI-970A-G43, advertises XMP support but it failed. After selecting either one of the 2 profiles, the machine failed to boot and I had to reset the BIOS via a jumper on the motherboard. That's obviously not what you're hoping for. I wasn't sure if it was my MB or the memory at fault, but I now believe it's my MB. My MB has an advanced function that let me see the XMP data and based on the timing shown in the data I was able to set all the timings manually. This wasn't obvious at all but after getting the settings in place, I rebooted and the memory works perfectly at 1866MHz. This tells me it's my MB bios that has a problem, not the memory itself. It would be nice if the memory packaging had a printed record of the XMP timings for those of us that *have* to set the timings manually. If my MB didn't have a way to see the XMP data, I would have been out of luck.

Pros: I bought two 8 Gb sticks and after a year of use one of the sticks failed. The other stick is going strong. I love the red color and looks cool.

Cons: 50% of the ram sticks I bought failed. I got tons of blue screens of death due to this ram stick. Was not sure what was causing it but suspected bad ram and sure enough I took out one ram stick and I have not had a blue screen of death since. (OR Ram dump screen)

Overall Review: I would expect Ram to last 4 to 6 years really.

Pros: Fast! Have mine OC'd to over 2200mhz even painted the heatsinks and no issues

Cons: none at all

Overall Review: great product absolutely no regrets

Pros: Ran Memtest with no errors, getting it to run at 1866 was very easy in the bios. Upgraded my old 8gb of Gskil ddr3 1600 ram. No reason to have more than 16gb of ram unless you're doing some serious multitasking. I wanted 16gb because it helps a little with gaming and I don't have to worry much about the handful of programs I have running in the background (like Nvidia's Geforce experience).

Cons: None.

Overall Review: Gskill has a life time warranty. Why would you ever buy from another brand when they have such great prices as well?

Pros: Looks great. Doesn't block aftermarket CPU coolers' fans. Fast memory!!

Cons: None to speak of.

Overall Review: I have had this set of RAM for two and a half years now and have yet to have an issue. They look slick, and they run just as advertised!
