Pros: • Price is reasonable for a mid-range set of DDR4, especially as DDR4 is new amongst PC enthusiasts. Ram prices come down as technology advances
• Reliability of Corsair products, I have had many different PC related products made by Corsair and the reliability and quality is world class.
• RAM support XPM 2.0 which allows for easy automatic RAM overclocking, DDR3 usually only had one profile
• The set is rated to run at 2400 Mhz (at 1.25v), that is obtained to use the XMP Profile 1, you can also set it at XMP Profile 2 which will allow it to run at 2666 Mhz at 1.35V
• RAM timings did not loosen up on the primary timings when choosing between XMP1 and XMP2, it remained at 14-16-16, tRAS did loosen a bit from 31 to 35 but that is negligible
• Low voltage required to run at rated and 2666 Mhz speeds. Low voltage result in low heat and you can’t go wrong with that in terms of MTBF
• Color scheme, it is a personal preference, it goes well with my Asrock X99X Fatal1ty Killer board.
• RAM sticks are low profile, so it does not interfere with aftermarket air HSF (Heat Sink Fans) coolers.
• Impressive bandwidth improvement over DDR3
Cons: • Honestly can’t think of any, price will come down in time as DDR4 migrates across all newer chipsets.
Other Thoughts: Newegg delivered my set of RAM for review speedily as always, I have to mention I was really excited as this is my 1st set of DDR4, for the last 10 years I have been playing with DDR2 and DDR4 RAM.
The retail box, yes it is a box unlike most RAM sets which comes in hard plastic shell.
The box contains two soft plastic shells each containing two RAM
sticks. The heat spreaders on the RAM are low profile so it won’t interfere with air cooler fins mounted on the CPU. The read finish on the heat spreaders looks pretty good.
I proceeded to install all four sticks onto an open bench rig containing the following hardware.
Intel i7-5820 k - Overclocked to 4 Ghz (44 x 100 Mz)
Asrock X99X Fatal1ty Killer motherboard
4 x 4 GB DDR4 Corsair Vengeance (this review)
Gigabyte GTX 970
OCZ Vertex 4 512 GB SSD
Rosewill 850 W PSU
Corsair H100i water cooler for CPU
The RAM set once installed runs at JEDEC speeds i.e. 2133 Mhz, this is it’s default, to get it to run at the rated 2400 Mhz speed simply go into the Bios and select XMP Profile 1 under DRAM settings, it will adjust the RAM and timings to the advertised specs. You can also select XMP Profile 2 which kicks the speed up to 2666 Mhz, it will add the necessary voltage to the RAM and set it to 1.35v
Once in Windows I ran a few benchmarks as comparison at 2133 (default), 2400 Mhz and 2666 Mhz
I used AIDA64 Engineering Version as well as Super Pi (SPi) 1m and 32 , in all cases I kept the CPU speed at 4 Ghz
SPi 1 M – 9.172 sec, SPi 32M – 8m 8.421 s
AIDA64 : Read – 46236 MB/s, Write – 51210 MB/s, Copy - 49263 MB/s. Latency – 69.6 ms
SPi 1 M – 9.140 sec, SPi 32M – 8m 2.71 s
AIDA64 : Read – 49330 MB/s, Write – 51352 MB/s, Copy - 53298 MB/s. Latency – 64.4 ms
SPi 1 M – 9.134 sec, SPi 32M – 8m 1.869 s
AIDA64 : Read – 51838 MB/s, Write – 51414 MB/s, Copy - 56537 MB/s. Latency – 60.4 ms
Differences does not seem very noticeable across SPi benchmark, 32M a bit more so where RAM speeds and timings play a larger role, SPi 1M is a benchmark influenced by CPU speed predominantly, in this case it stayed at 4 Ghz. I did not mess with the timings on each setting to try an tightened it as I ran out of time.
Looking at AIDA64 you will notice the jump in read/copy speeds with increase in RAM speeds, this is where you will notice a sizable improvement. The latency dropped a bit whereas write speeds stayed flat.
As reference I am pulling in some bench data (AIDA64) from a fellow overclocker (LVCOYOTE from overclockers.com) on DDR3 2400, also a set of 4 x 4 GB.
Kingston HyperX Beast DDR3-2400 Read – 35903 MB/s, Write - 37565 MB/s, Copy – 34834MB/s, Latency - 44.7 ns
Even at lower speeds the DDR4 has a much higher bandwidth than the DDR3 RAM, then again X99 chipsets brings quad channel capabilities vs dual capabilities yielding higher bandwidth so it is not a contest really. I just wanted to bring the reader another set of data from the soon to
This review is from: Seagate Backup Plus 5TB USB 3.0 Desktop External Hard Drive STDT5000100
Pros: - Drive came in a retail box securely packaged.
- 5 TB, lots of disk space
- Seagate Dashboard is a user friendly interface to back up files even mobile data, restore files, all with the click of the mouse
- Drive is pre-formatted and came with software for Dashboard
- Drive came with a 5 year warranty, more than most drives
- Good read and write speeds for such a huge drive
- Can connect with Cloud to sync data
- Very quiet drive, cannot hear it over the noice my PC fan makes
- USB 3.0, almost all new drives are 3.0
Cons: - There is no on or off switch, you have to disconnect the power cord to turn the drive off, very odd.
- There is only a half inch thin LED light on the top to indicate the drive is on, could be more exciting I guess. The light dims in and out slowly to indicate activity, it does not flicker like most external drives do.
- The drive can only be put on the table flat, not on it's side if you want to safe real estate on your desk
Other Thoughts: Newegg delivered the brown box promptly for this EggXpert review as always.
The drive came in full retail box packaging which includes the external drive, USB cable and power adapter, it also has a quick installation guide that takes you through the setup steps.
The drive has a shiny appearance on the top as it lays flat, matte black on the four sides and light blue on the bottom with four little stands.
The drive measures 7" x 4.5" x 1.5 " and from the weight it is a full 5.25" drive, to be expected to carry such high capacity
Once unpacked I proceeded to plug in the USB 3.0 cable and power adaptor, Windows installed the drivers in a few seconds, the drive came with two files ie Seagate Dashboard installer and the Warranty, the latter indicates that the drive has a 5 year limited warranty, the document spells out what is covered and what not.
Even though it is 5 TB advertised drive you get 4.54 TB of space, plenty to store your precious pictures or to backup your gaming or personal computer.
I ran ATTO disk benchmark and the average of 5 runs produced the following read and write speeds:
Read : 163 MB/s
Write : 163 MB/s
Not bad for such a monster drive
Pros: - Runs cool,
- Fans are very effective and can barely hear it when running at peak load
- Powerful card
- Good Price point
Cons: -Coil Whine, did not expect it from the Gigabyte cards, when running MSI Kombuster stress test the whine is very noticeable
-Unable to use DP cable, black screen after Win logo
-Drivers are not mature, very disappointing, see below
Other Thoughts: After removing existing drivers I installed the card on a Z97 board, boot up into Win no problem. i then installed the latest nVidia drivers, start up the PC and lost signal after Win logo. I then cleared CMOS, tried several older drivers and the same thing, every time I had to swap the new card with an old card to uninstall nVidia drivers.
I'm a Newegg EggXpert reviewer and PC power user for nearly 10 years and have reviewed many cards on both AMD and nVidia side and this is the 1st time I had issues with nVidia GPU's, very frustrating.
I then changed to HDMI cable, was using a DP cable at first, same issue , I power cycled the PC for about 10 times and then all of a sudden my signal was restored. i was about to RMA the card back to Newegg, if it was not for the non-refund on this particular card I would still do it and get a MSI or Asus card, only exchanges allowed unfortunately.
Coil whine was not expected from reading some reviews, looks like I struck it unlucky, very noticeable coil whine when running games or stress tests using MSI Kombuster.
