Question: If i want to upgrade to 32g,can i just buy another one of this set ? or does 32g have to be bought in 4-8g stick set
Document: I was looking to upgrade my ram from 12 GB to 16, and was considering dropping my current set up (3 sticks of Corsair 4 GB 1300mhz DDR3 RAM) in favor of a faster clock speed, seeing as how I wasn't taking advantage of my motherboard at all.When it came time to upgrade, I was astonished by the gap in performance!
Bought this for a new build. MB is a Z87 Sabertooth. The DRAM light stayed on during boot and the system would not boot up. I noticed one stick was VERY HOT. The other was nice and cool. At first I thought maybe I had an issue with the MB. But after switch the pairs the same stick remained HOT.Thank you Amazon for the great service.
I really contemplated between 4 and 5 stars on this one. The RAM is absolutely solid, but not at 2400MHz, it's solid at about 2133MHz. When trying to run at 2400, I did get some crashing; so clocked back to 2133, and couldn't be happier. If you really want to push the 2400MHz clock, I'd go with something a little different.
I had the same experience as many other reviewers here, this ram won't run at 2400 on my system.Sending it back to try another brand.One star
Ive bought Kingston hyperX ram of various types at least 3 or 4 times and I have never had a problem with it.This particular ram is some of their best.Added a point and a half to Cinebench score by just bumping it up from 1333 to 1600.
Again it's RAM.It does its job, isn't corrupted like 1 set I bought.So yeah... Im not sure how much the 2400 MHz aspect of it helps but hey it works for me.It is currently in my gaming PC and I can pretty much run anything.
Solid matching set of ram that does the job in two fewer sticks. I had 4 sticks of ddr 3 that made 16gb and I'm glad now to make it just 2 sticks for the same effect. Install was a breeze and the computer had no problem recognizing the ram and setting the correct timings.
Originally comes clocked at 1333MHz. Using the overclocking features in my motherboard (MSI Z87-G45), it's REALLY easy to set up. I have it running at 2000MHz, and I could go higher but I don't feel the need to. This memory is fast! However, i wish it came pre-set to 2400MHz. As someone who just built my first PC, I thought it was just plug-and-play at 2400MHz; turns out there's just one step in between.
But I got everything running the way I want it to and everything's good now.
Nice set for the price and a life time warranty to boot.Seems to be functioning as described, no install issues.
Answer: Yeah you can just buy another set it's better buying a quad channel set but this will do fine and most of the time people don't even need 32gb anyway
