G.Skill @ it again. 11/18/2019 6:35:31 PM

Pros: -Easy to set up
-fast with 5820k
-G.Skill made another great product

Cons: -No cons to report thus far

Overall Review: I've rocked G.Skill in my past rig and now this one. I see too many negative comments which looks like lack of BIOS knowledge. I had DDR3 G.Skill in my 3570K and now this Quad set paired with a 5820k on an Asus X99 Sabertooth. Works like a champ. You will have adjust the XMP profile but it will run the 2666 as advertised. I haven't tried to push it past 2666 because it works so well with the 5820k @ 4.4ghz. Couldn't ask for much better. Thanks G.Skill, you have a repeat customer on your hands.

Good memory 7/30/2017 5:12:45 PM

Pros: No problems at all on EVGA X99 Classified, correct timings, voltage, and clock from the start. Seems to be rock solid so far, time will tell. I ran the first set of these for over a year and a half, and still going strong, so added a second kit to fill up my mobo's slots. They OC quite well, but they scored better when I tightened the timings and set to 1T vs increasing the frequency. I still think this was the best kit of the series vs the higher and lower frequency models.

Cons: None really.

A little uneasy 6/9/2017 1:40:59 PM

Pros: -The product looks cool.
-The price is decent.

Cons: -Possible RMA on the ram.
-Actual clock is 2133.

Overall Review: I've had a few problems with this build since week 1. Many blue screens that point towards the memory being faulty. Did extensive memtesting and had one stick that consistently errors in one slot on the motherboard, but tested okay elsewhere. Spent probably 100+ hours testing these 4 sticks on this motherboard and I cannot conclude whether I need to RMA the mobo to see my problems stopped or RMA the ram. Either way, I'd be down and out without a computer for a while, which just isn't possible.

Manufacturer Response:

Hi Dustin

We can clarify and help with any unease you may have. The AUTO default clock speed is DDR4-2133 (1066MHz) for DDR4 RAM. This standard frequency allows the RAM to be compatible in most DDR4 computers. In order to enable the performance values of the RAM, activate XMP Profile in BIOS to allow the system to recognize the proper settings.

When experiencing blue screens or memory related errors, test one module at a time to see if a stick performs differently than others. Also, make sure to have the latest BIOS for the motherboard. If a module performs differently than others and appears defective, send them in for RMA exchange and we can have new replacements out to you shortly. Visit the G.Skill website for complete RMA procedure. For any questions or concerns, please feel free to contact us directly.


Thank you

XMP Delivers As Promised 7/1/2015 7:46:27 PM

Pros: This RAM was on the qualified list for my motherboard and the product worked as advertised with the XMP profile with no added fuss or stability issues. I could overclock it even more, but have elected not to for now.

Cons: None

Overall Review: There is more headroom for overclocking and/or tighter timings in this memory, but I'm pleased enough with its performance as-is to leave it in its stock XMP profile settings.
