4 out of 5 eggsExtremely Good Memory for AMD users

Pros: I found it to run relatively cool, even when running at 2400 speed. I also love how it's not pointlessly tall like other high performance memory modules, so your options for air-cooling on the CPU isn't limited by Memory with ludicrously tall fins.

Definitely gave a boost to my AMD based machines. More-so the AMD A10, which uses the extra bandwidth provided by these to give the APU even more performance on tasks for graphics. I felt a tangible increase in performance on my FX-8350, AMD cpus seem to love fast ram.

Also works well with Intel machines. I tried it in my I5 2500k and 3770k machines and it ran fine. Didn't notice as big of a jump going from 1600 to 2400 as I did on the AMD PCs, but Intel CPUs are pretty high performance to begin with.

Cons: For an Intel based gaming machine, you may be better served with either cheaper DDR3-1600 or More DDR3-1600(say 16GB) for the same price. These are expensive, and are only 8GB, which while fine for gaming, I felt limited when I did video-editing on my FX-8350 and i7-3770k machines.

Other Thoughts: I found this RAM to run reliable in all my machines and, at least with my AMD machines, found a tangible performance increase. If you plan on putting these in an Intel based PC, they work fantastically, but you may be better served with DDR3-1866 or DDR3-1600 for similar money.

1 out of 5 eggsFollowup review

Pros: They are low profile

Cons: They do not work in the two motherboards that I have tested.

I tested in a gigabyte zs5 z87 board and in an asrock s77 itx-e board.

both gave me endless boot loops. 1 stick or 2 sticks in any slot tested. I figured the asrick z77 would not work as it is an older board. the gigabyte is a new board. I will test a newer gigabyte board this week.

Other Thoughts: I had hoped the gigabyte board would work.

5 out of 5 eggsFast and 100% stable

Pros: Perfect match for Kaveri A10-7850K and Gigabyte F2A88XN-WIFI.

Enabled AMP in BIOS and it automatically configured the correct memory frequency and timing.

Modules are low profile so it's compatible with Noctua NH-U9B SE2 cooler.

Lifetime warranty

Cons: None

5 out of 5 eggsSlick Sleek Sticks

Pros: Fast… very fast!

Cons: More an observation than a con, if you are on 2133 then upgrading to these may not see significant gains.

Other Thoughts: I installed these sticks on two different machines just to see what the effect of using this fast RAM on a fairly new desktop and then on a low-mid range gamer.

MSI 970A-G43
AMD FX-4100 Zambezi 3.6GHz
Previous Memory Kingston HyperX 2 x 4GB DDR3 1333
ZOTAC GeForce 8400 GS
Corsair CSSD-F60GBLS SSD Boot Drive
WD Green WD10EZRX 1TB Data Drive
Windows Professional 8.1

This system scored 7.3 in Windows Experience Index for Memory.
After replacing the memory with the Radeon R9 2400 the memory score improved to 7.9, this is running the memory as 2133 which is the fastest this particular motherboard will OC to. The installation of these memory sticks was the fastest and easiest setup I have experienced with high end memory, in the past tweaking memory performance involved changing settings, rebooting, see if it will make it to windows, if it did make it windows run a couple of memory intensive operations to make sure the system was stable, if these came out ok you were good to go. This smooth progression from installation to usage very rarely happened, usually it involved reboot/change iterations which a smart user would document to keep track of the combinations of settings you had eliminated. This was made all the more tiresome by the need to reset the CMOS settings if a motherboard would refuse to post due to changed settings. Resetting CMOS meant reentering all the CMOS settings manually, these were the days before CMOS profiles and sensing failed settings and rebooting to the old settings features. Thank the FSM those days are over. Modern motherboards detect boot failure and take you back to the BIOS with the prior settings. This particular motherboard actually had AMD profiles built into the BIOS so it could detect the memory installed and automatically configure the timings required. The combination of fast memory and SSD makes this a very fast system for run of the mill tasks, the graphics card is bleugh for games though. So I took the sticks out of this system and installed them into the following setup.

ASUS A78M-A FM2+
AMD A10-7850K Quad Core FM2+
Previous Memory G.SKILL Sniper Series 2 x 4GB DDR3 2133
AMD Radeon R7 – APU based
Toshiba HDTS212XZSTA 128GB SATA III SSD Boot Drive
2 x SAMSUNG Spinpoint F3 500GB 7200 Drives

To be honest the improvement was minimal, there were a few FPS gains here and there but the difference between 2133 and 2400 MHz DDR3 is barely noticeable. I pulled out the 2400 and stuck in the 1333s from the other system, did a few frame checks and compared these to what I was seeing with the Radeon R9s. Now that’s where you will see the difference. Running Batman Arkham Asylum, I know it’s old but it’s one of those games I play frequently, I was seeing a gain of about 5-10 FPS going from the 1333 to the 2400 setup. With the fall in price of these 2400 kits in the last year and their increasing availability you gotta do it! Besides the minimalist design of the sticks and their heatsinks looks pretty n

5 out of 5 eggsfirst of a three part review.

Pros: N/A

I will report on my two mother boards the gigabyte and the asrock in about 1 week

Cons: N/A

I am an eggxpert reviewer.

Other Thoughts: I game a bit not much , but I mine a lot. I have read on more then one mining site that faster ram improves mining speed. So when newegg offered me a chance to review this ram as an eggxpert reviewer I said yes. I plan to test this with two motherboards. I have a gigabyte motherboard purchased from newegg about a month ago. It is the gigabyte g1.Sniper Z5S board. I am running an asus r9 290 gpu as a miner of ltc it is giving me 832khs. I am running 11 ice 'nano' fury usb sticks and they are clocked to 54 which gives about 2.5gh a stick mining btc total of 27.5gh. I use mushkin ram 8gb a stick 1600 speed. my goal is to do a simple swap of sticks and see if my gpu runs faster mining ltc and also see if my 11 usb sticks run faster mining btc.
It is exciting that better pc gear has the ability to earn some money when you are not gaming or using the pc for the net/movies etc. I live in New Jersey and running a pc with a few gpus give off some nice heat which came in handy this winter. My main goal is to see that { A } the Sticks work with this motherboard { B} improvement in mining speed {c} power increase or decrease.

The other motherboard is an asrock z77 extreme itx this runs with 2 samsung 4gb 1600 vlp sticks of ram. It runs an asus r9 290 gpu at ltc it runs 1 set of six gridseed 5 chip ltc/btc miners it runs 5 antminer usb sticks and 1 red fury usb stick. all in all it has 9 separate mining programs running.

6 cpuminer for the six girdseed units mining LTC

1 cgminer for the 5 antminer u-1s mining BTC

1bfgminer for the single redfury stick mining BTC

1 gui miner for the gpu mining LTC

A VERY complex load on the cpu and the ram. goals are the same
A) will it work
B) will it help mining speed.
C) will it use more or less power

5 out of 5 eggsAMD R9 Gaming memory - performs well and is stable

Pros: Installed easily on my ASRock Z87E-ITX system (an excellent mini-ITX motherboard, BTW). I simply set the XMP profile in the UEFI and got the stated speed of 2400MHz and 11-12-12-31 timings at 1.65V, so it is compatible with Intel motherboards. I am using an i3-4130 CPU at stock 3.4GHz, so it was nice to see the lowest Haswell i3 can handle it without problems. I ran the built-in Windows 8.1 memory checker after installation and it came back with no errors. CPU-Z confirmed the speeds set in the UEFI.
The heatsinks are attractive and more importantly, very low profile, so they should fit under any CPU cooler.
I ran some speed tests of my own after setting up a 2GB FAT32 RAMDisk with the utility that came with my ASRock motherboard, to see what improvement there was at 2400MHz vs 1600MHz with slightly better timings (defaulted to 11-11-11-28 at 1T command rate vs the above at 2T). I used CrystalDiskMark to get these measurements. The greatest improvement came with large sequential writes of 7411 MB/s (2400) vs 6542 MB/s (1600) and sequential reads of 7866 MB/s (2400) vs 7149 MB/s (1600). 512K writes showed similar improvement but were around 200MB/s slower across all tests. For the smaller random 4K reads/writes, there was some improvement, but only about 11-20 MB/s across both sets of queue depths eg 998 MB/s (2400) vs 987 MB/s (1600) for queue depth 1 4K reads.

Cons: For gaming, I would not expect noticeable improvement unless you are using an AMD APU or an Intel board's IGP. With a GTX 670 discrete video card, I did not see any difference in game performance.
Not really a con with the memory itself, but I downloaded the AMD Radeon RAMDisk free software, and it did not recognize my memory as AMD Radeon, so it limited the RAMDisk size to 4GB, and not the 6GB promised.

Other Thoughts: This definitely performs better at 2400MHz than 1600MHz, at least under specific tests, though I am not sure if it would affect your gaming experience significantly with a discrete card.
Note: The AMD RAMdisk defaults to NTFS format without needing to go into WIndows Disk Management, so it can store files over 4GB, as opposed to the default FAT32 of ASRock RAMDisk and the original RAMDisk from Dataram (source company for all three versions), that I also own. An NTFS RAMDisk is better for large sequential operations than storing a browser cache and Temp directory files, for which FAT32 has less overhead.

For me, this memory might be better suited to video editing especially with a large RAMDisk to work on the video files.
It costs quite a bit more than 1600MHz memory, and I would rather use the savings on a faster CPU (Note: I received this item for review from Newegg). I'd dock it half an egg for price, however it does perform as described, i.e. very well, so I'm rounding it up to 5 eggs rather than down to 4.

5 out of 5 eggsAMD 2400 gaming ram

Pros: Small form factor for those with overlarge CPU coolers.
1333 ,1600,1866,2400 speed
XMP profile for Intel CPU
Will run at 1.5 volts with 1866 or lower speeds.
Lifetime warranty

Cons: This is the only con I can think of and it is for those that don't manually set timings or feel comfortable in bios.
Defaults at 1333 without adjustment
XMP profile reported by CPUZ is 3T so wont load the XMP with an AMD chip and run.

Other Thoughts: I read the reviews when I was offered these to review. At that time they had 3 reviews and all were less than 5 eggs and complained of 1 stick not working or the XMP profile not working. So that interested me and I agreed to review these. Upon first start up they loaded at 1333 which to me is normal as higher speeds are usually posted as overclocking. I installed windows 7 with them running at 1333 with timings of 9-9-9-25-35. I had no problems installing windows. Once installed I rebooted and set them at 1600 with timings of 10-10-10-28-40 and installed about 40 updates, There were no hang ups and I could notice a speed difference no huge but it was there. I then restarted and did 50 more windows updates with them set at 1866 with timings of 12-12-12-34-46. To me the speed was about the same as with them running at 1600 with tighter timings. I saved 54 windows updates for the last test with them running at 2400 with timings of 11-12-12-30-57 which is better than what they are rated at. At this speed I did notice a huge difference between 1600 and 2400. Impressed me a bit.
I then restarted and tried to load the XMP profile and the computer wouldn't boot just gave me the famous loop so I manually set the timings back to 2400 and restarted and it booted just fine. At this point I downloaded CPUZ to see what was going on, Under the SPD tab it did show an XMP profile but even thou these are dual channel ram CPUZ reported the XMP was triple channel. Now I know why it wouldn't boot off the XMP.
I left them at 2400 and started a mem test. I figured I would put this ram thru it paces. This is on the third day of running them so they did get a short break in period. I ran mem test for 4 hours without a single error.
I would trust this ram in my system and will most likely put them in the next one I build as I use 16 gigs in mine at this point. In 14 or more years of building computers I have only once had to send ram in because it had failed therefore the lifetime warranty on all ram.
As I didn't have to contact AMD support or RMA these memory modules I can not attest to how quick the turn around time is or how fast you would get a rma number.

4 out of 5 eggsAMP RAM Good!!!

Pros: Meets spec no problem (can you say PRIME95?)
So awesome easy to set in BIOS to get spec performance
Improved Win8 WEI video performance by 15% over 1600 ram
Not DOA?? (that's for the whiners...)
Lifetime Warranty (who's life?)

Cons: Sold above MSR by a couple of bucks. All for convenience? Yes, I paid it...

Other Thoughts: On boot, required F1. Chose AMP setting in UEFI BIOS. Perfect from then on. What's not to love?

HTPC System:
ASUS A88XM-A
AMD A10-7850K FM2+
Radeon R938G2401U1K (This RAM)
LG WH10LS30 BDRW
Antec NSK2480 HTPC Case (a classic gem)

4 out of 5 eggsNice Memory

Pros: Nice bandwidth bump
It has an attractive design
Timings are decent for the speed

Cons: - The price is a bit high
- Couldn't push them much further than the rated speed, even with extra voltage.

Other Thoughts: I dropped this ram into my test system which consists of

Intel Core i7 2600k
Gigabyte Z77 board
2x SSD in RAID0
2 conventional 3TB drives for storage
GTX 670 video

These are low profile, so they should fit below that new monster heatsink you just bought. My board immediately set the voltage correctly to 1.65v, but I had to manually set the speed. Boot times seemed unchanged, though my Window Experience Index memory score increased by a tenth of a point.

Next I tried bumping the RAM up slowly, but quickly hit a wall that left me no choice but to clear cmos settings, and retry. If my memory serves (pun intended!), it topped out at 2468. It was definitely below 2500 even with a voltage bump, so not much headroom for overclocking.

I would likely recommend this memory to anyone that does not want to overclock, but wants the bump in memory bandwidth one might get from overclocking. Of course, if you are an AMD Fanboy, you will probably want these just for the AMD logo and design alone - and that's fine, they do look great!

If you are just looking to add some memory to an average system - there are better, and cheaper options available. You don't need DDR3-2400 :)
