Pros: Overall, this RAM was very fast and easy to set up with one single XMP profile available in the BIOS. I tested this RAM with an MSI Z170 Gaming M3 motherboard and an i7-6700K CPU and 240GB SP60 SSD. The heat spreaders were thick, heavy, sturdy, and not very tall which helps out a lot.
I tested this RAM with the default JEDEC timings, which I don't recommend anyone use, and then tested it with XMP enabled. The XMP speeds were around 15% faster across the board and XMP is the proper way to configure high end RAM so those are the only speeds I will post in this review.
3411 Memory Mark speed
30,418 MB/sec read speed
15,948 MB/sec write speed
19.5 nanoseconds latency
Those speeds beat known scores for other similar DDR4 RAM kits. Given those performance numbers, the price on this RAM kit is a very good deal!
Cons: Trying to configure this RAM properly was a bit strange. It was straightforward but misleading and confusing and that's never a good thing.
I had very inconsistent problems with the A00 verson of my BIOS on my motherboard but flashing to A20 cleared it right up so I'll only post about my complaints with the latest version. The entire problem was caused by the fact that this RAM is allegedly 3000MHz RAM but 3000MHz isn't an actual operating speed for DDR4. The steps are 2926 and 3059. To get to 3000 on the dot, it had to do some strange things.
By default most motherboards will leave the RAM at the highest JEDEC table settings which in this case was 2133MHz 15-15-15-36 timing at 1.20 Volts. Once I turned on XMP, it changed my CPU Bclck (so basically the FSB) on the entire board to 102.31. It suggested this was because the RAM speed was calculated by 22x100x1.33 which would only be 2926 MHz. Since the XMP spec wants 3000MHz, it simply changed my motherboard's FSB to be 102.31 instead which resulted in 3000. The timings matched the listed specs though at 15-17-17-35 at 1.35 volts.
Everything worked great and the RAM reported running at 3000MHz in Windows but overclocking your FSB can cause instability and problems with other devices like your graphics card, not to mention making your CPU run a little bit hotter and at a higher frequency than it was designed for. A 2.31% overclock isn't much but it's still overclocking and still may cause problems immediately or over time. For a set of RAM to have to do this just to attain its normal speed can only be what I'd call dangerous and stupid. Luckily on my motherboard I could turn XMP on then override the change to my FSB and set it back to 100. It lowered the RAM speed down to 2926MHz but the performance tests were so close, I'd prefer stability and safety over that tiny speed difference. If it really bothers you, my motherboard at least let me change it to 23x100x1.33 speed which resulted in 3059MHz RAM speed while leaving the FSB at 100.
Overall this small annoyance was due to math and exact clock speeds, etc and makes very little difference but it certainly was annoying and wasted a little bit of my time. I had to take 1 egg off the rating though because RAM that alters your FSB just by turning XMP on, assuming my motherboard wasn't at fault for doing that, is completely unacceptable, though you can override it.
Other Thoughts: All things considered, this RAM tested at extremely fast speeds! Number ratings are just theoretical so if you look solely at the actual real world RAM speed that this kit tested it, it's very fast, even for DDR4.READ FULL REVIEW
This review is from: G.SKILL RIPJAWS SV710 Dolby 7.1 Surround Sound USB Gaming Headset
Pros: The headphones arrived in very thick, safe packaging which is especially important for headphones. The connections felt solid and sturdy and the headphones' structure did as well.
The driver loaded within 10 seconds of plugging the device in and it set itself as the default output device automatically. So basically I plugged them in and they worked.
The audio quality is not so great. They beat bottom end headphones but they're far from the quality of my two other pairs that are in a similar price range. The bass tones were there and a steady volume across the spectrum but they were a little too low in my opinion. I turned on the “bass boost” enhancement that is provided to almost all audio devices in Windows and it sounded much better. The initial lack of bass is surprising given the USB power available to help produce low end frequencies. The mid tones were represented well and were clear and appropriately leveled. The mid-high tones like guitar and piano notes were mushy, slightly distorted, and sounded a bit low quality not to mention leveled too high compared to the other frequencies. The highest frequencies like 10KHz on up were very clear and sounded great. Overall I'd say the audio quality was moderate but noticeably imperfect and at times mushy and badly balanced or distorted. Keep in mind I've worked in a professional audio editing, mobile DJing, and concert and theater sound production though.
The microphone was very impressive. I loved the slide-in feature. It wasn't professional quality but it and not quite passable for use in basic narrations and voiceovers like for online video sites. It was a little midrange heavy and didn't pick up bass or high frequencies well at all so you end up sounding nasaly and mushy. Other players in an online game or video chat would easily understand every word you say though. For fun I tried recording vocals for a music track and it sounded so unbelievably bad, there aren't even words for it but that's to be expected. Headsets never record sufficient quality for singing.
There was zero background noise whatsoever unless I put the input sensitivity past 85% in my recording program. Unfortunately that means that without dimming the sensitivity, the mic sends static, but it's not normal to record at 100% with any microphone. The mic picked up a little bit of air noise while placed directly in front of my mouth but retracting it slightly fixed that completely. It's the best you can ask for without a full wind screen.
Cons: These headphones are extremely loud compared to the average level achieved by analog ones that plug into the audio ports. This is likely due to the USB power amplification. I had to listen to most music at 2-5% volume. At 10% volume I would estimate the SPL inside the nearly airtight chamber around my ear at 105-110 decibels. I didn't try it at a higher level because it would likely damage my USB port from power draw or the headphones themselves. That is such an unbelievably unacceptable defect, I had to take off a lot of eggs in the rating. I was going to call them passable quality overall but in need of slight improvements but this knocked it down to completely unusable status.
To make things worse, under “custom” in the Speakers Properties window accessible via the Sounds option in the Windows 7 start menu, there is only one feature and it is simply titled “loudness.” Turning it on makes the output EVEN LOUDER!
To make matters worse, instead of an inline variable resistance device like on analog headphones, the volume up/down control in the cable simply signals the volume to raise or lower in Windows. Also, my system thought they were Speakers after loading the default driver from Microsof'ts Windows Update servers. The levels are so outrageously wrong, the headphones are almost unusable. Since it loads as an entire audio device, any advanced features in your sound card driver to redefine the device type of override the levels won't work.
In my recording program, the Gskill audio device registered a SPDIF, Line in, and Microphone source as being valid and available. Obviously it only has a microphone. Once I configure it to target the correct “device” I was pretty happy with the quality.
These headphones claim to virtualize 7.1 surround sound but in fact the sound configuration options in Windows state that the device is only capable of stereo surround and no other options are available except the default surround virtualization that uses matrixing which any audio device can use.
Other Thoughts: As a pro and a con, the cable leading to the headphones is extremely thick and heavy. This makes it resist damage but you can certainly feel it pulling your head to one side.
My super short summary of these headphones is that they are imperfect, the sound levels will blow your head off, and I can't get past the fact that there are much better headphones out there in the same price range. I don't think these are a good choice until a few problems are solved.
Note: Gskill has stated that frequency leveling may be smoothed out in future driver updates. I am using the Microsoft July 12, 2013 driver version 6.1.7601.18202 for this test, which is a sort of generic audio device driver but I couldn't find any alternatives.
Pros: The PSU was inside of Corsair's usual beautiful packaging. The box looked great for retail displays. The first thing I noticed was the weight. Heavier usually means more metal and larger/better components so heavy is good for power supplies.
The configuration is single 12V rail at 62.5 max Amps, which is the ideal way to build a power supply. To maintain gold level efficiency at those levels means the components are absolutely top quality.
The options for modular cable branches were perfect for my build and flexible even if I had additional components to add in the future. All the hookups were solid and didn't feel like they would slip off of the components. Even the 24 pin connector latched on securely and without excessive force needed. The 8 pin CPU connector was sufficiently long to route through the back of my mid tower case instead of having to cross the motherboard, which is incredibly important. The inclusion of matching accessories like the molex converter, etc was really nice and saves money on side orders for adapters you're still needing or even just the cable ties. The SATA power branches had right angle options, which worked great with my case's sideways and backwards mounted hard drives.
I artificially raised the temperature of the PSU to hear the fan kick in at a high speed and it wasn't very loud even then. The air coming out of the PSU was surprisingly cool even at a 410 watt draw measured at the outlet. The efficiency is really nice and helps to not overheat your room or damage the PSU internal components.
Under very heavy load, the 12V rail was still reading at around 12.15V and didn't fluctuate much so this unit would be great for overclocking. Overall there was no arcing, sparking, or high pitched noises, which is exactly what I would expect from a PSU with a 7 year warranty on it.
Cons: Honestly, I would prefer the fan to be on at all times but at a 20 or less decibel level. Just because the components can run at a hotter temperature doesn't mean they should. The automatic fan turnoff is more of a gimmick than a real feature and sound level isn't really the difference since the fan is so quiet anyway.
Other Thoughts: This power supply's weight will make it a lot harder to transport your desktop to a LAN party so keep that in mind. Lighter means cheaper though so it's not actually a negative thing to have a heavy PSU.
Keep in mind that cheap power supplies with fluctuating voltages, low voltages, and poor surge suppression can destroy your components, especially graphics cards. So don't get a cheap budget power supply for your build or you will pay for it in the long run!
