ZyXEL PLA5405KIT HomePlug AV2 MIMO AV1200 Powerline Gigabit Ethernet Adapter Kit, up to 1200Mbps
  • neweggOwned For: 1 day to 1 week

Pros: Big improvement in throughput compared to previous generation powerline networking. Because this is a MIMO product instead of a SISO product, it uses multiple data streams (specifically the hot-neutral and the hot-ground wire pairs) to increase bandwidth and counteract interference. It works, although you won't get anywhere near gigabit speeds unless the two adapters are on the same physical circuit and there are no interference sources in between the adapters.

Cons: A bit expensive. If you are happy with your current powerline setup, it's probably better to wait for the next iteration of powerline adapters. This one only operates on ~10 - ~65 Mhz frequencies. The AV2 spec allows for powerline devices to operate in a frequency range of ~10 - ~85 Mhz, which allows for more bandwidth. I dinged this a star because of the price.

Other Thoughts: The powerline industry seems to have taken a play from the Wi-Fi world by advertising theoretical peak line rates instead of real world data rates (data rate = line rate - protocol overhead). Just like Wi-Fi, you will not get the advertised link rate in the real world. Powerline networking bandwidth can also be limited by any one or more of the following factors:

-Type and Quality of electrical wire in your house (i.e. thickness of wires (10 guage vs. 12 guage vs. 14 guage, age/condition of wires - older wires may suffer from corrosion, material of wires - such as aluminum vs. copper)

-Length of the powerline. For example, one of the rooms in my house is on two different electrical circuits on my electrical panel. Even though the 2 outlets are 10 feet from each other, data travelling between the two outlets has to travel several hundred feet as the signal goes down to the panel in the basement and comes back up on the other circuit.

-Location of other electrical appliances and devices. These generate line noise similar to the interference multiple Wi-Fi routers near each other would cause. It's best to have as few things plugged into the powerline between the two adapters if possible. Every device will have a different impact due to local environmental conditions.

- Circuit breakers in your breaker box matter. If you're trying to cross multiple circuit breakers in your breaker box, this will kill performance between two adapters. Arc-Fault and Ground-Fault adapters are the worst offenders, although some are manufactured in a powerline networking friendly manner.

XFX Double D Radeon HD 7970 DirectX 11 FX797ATDJC 3GB 384-Bit DDR5 PCI Express 3.0 CrossFireX Support Video Card

1 out of 5 eggs Piece of Junk and Technical Support is a Joke 03/28/2014

This review is from: XFX Double D Radeon HD 7970 DirectX 11 FX797ATDJC 3GB 384-Bit DDR5 PCI Express 3.0 CrossFireX Support Video Card

Pros: It's a shorter card than some of the other 7970's on the market. So you get better air flow if you put this card in a large case, or you can choose to put this card in a smaller case.

Cons: The card is defective. It took me forever to diagnose the problem, but my particular card causes display artifacts to be rendered, frame stuttering, and then my computer to do a hard-freeze when playing games that use Directx11. I've been able to confirm its not a driver problem, software or computer configuration problem, but I can reliably reproduce the fault. It appears to have a faulty chip that doesn't handle DirectX 11 properly

However XFX's customer support is a joke. I contacted their support and explained the problem. They (specifically someone named "Krell") asked me to send them a copy of my invoice and asked me one or two clarifying questions. That was 5 days ago and I haven't heard back from them since despite repeated attempts to contact XFX. Now, I'm left in limbo.

You buy enough parts and eventually, you will buy a bad one. It happens. What is unacceptable is when a company doesn't stand behind their product or warranty or provide even a minimum level of customer service. Spend your money on a card from another manufacturer. If you buy a bad part, at least they will stand behind their products and not leave you hanging when you need help.

Pros: See previous review entitled "Not Product Advertised." Although the sticks do not contain XMP profiles matching their advertised timings, I was able to manually set the timings and speed in my BIOS. They appear to be functional and stable.

Cons: The heat spreaders are *THICK*. Too thick. Placing two of these sticks side by side in my motherboard had the heatspreaders of the adjacent ram contacting each other. This leaves no room for air to travel between the ram sticks. It also makes it hard to grip a RAM stick after you have installed it. I have never had this problem before - the heat spreaders of my previous Ram did not contact each other.

Other Thoughts: I did not knock off an additional egg for the over-sized heat spreaders because it does not appear to impact my system. In my experience, RAM heat sinks are more bling than functional. I've never had RAM get hot or overheat, but then I always run my RAM at stock/standard compliant voltages (e.g. 1.5 volts for DDR3). Heat sinks might be necessary for overclocking your memory by increasing the voltage. If so, see my comments above about the lack of airflow around the DIMMS when you install these.
