Pros: Comes with an awesome Crown Royal-esque bag. Modular. Visibly superior build quality. Plenty of power, no inflated specs. I'm running an AMD FX-8320 overclocked to 4.7GHz, 32GB RAM, dual ATI HD7870 Sapphire GPUs, 5 hard drives, 1 SSD, six 120mm fans, one 140mm fan, one 200mm fan, and one 230mm fan. PSU generates almost no heat. Quiet, with the option of running it fanless. Amazing price (on sale)
No coil whine (See other thoughts)
Cons: Expensive (if not on sale)
Coil whine at first (see other thoughts)
Other Thoughts: My old system started producing coil whine when I upgraded the FX-6350 to a 8320. Gigabyte GA-970A-DS3 with a Corsair TX-650 PSU. Upgraded to ASUS M5A990FX PRO R2.0 with this Seasonic 660XP2 and it still produced coil whine. I was quite distraught, until one day I took the system out to the garage because it was around 10 degrees outside that night and the cold garage was a perfect place to do some overclock testing. Plugged it in, powered it on, ZERO coil whine. Took it back inside, coil whine returned. It was the UPS. The one in my office was an older APC, while the newer APC that the servers were on in my garage actively filtered the power, rather than just kicking on when there was an outage.
So to anybody having coil whine problems with this PSU, try testing on a different UPS. Possibly one with AVR. I know I installed an identical PSU in another server I maintain, and it produced zero coil whine when plugged into a CyberPower Pure Sinewave UPS. This is a premium PSU and seems to require clean power to function properly, kind of how you wouldn't put regular unleaded gasoline in a Ferrari.
Pros: Best chip I have ever owned. Close to the best I've ever operated. Lets break down why:
1. Overclock City
I've read about the bin process AMD uses, and I don't know if what I read is accurate, but the auto overclock feature on my ASUS M5A99FX PRO R2.0 puts this thing at 4.2GHz, so I know the cores are of a higher quality than the 8320 label would suggest. It goes higher, and remains stable, but I hit a temperature wall. 4.7GHz is the highest I can get it and still be able to run Intel Burn Test without it getting hotter than I am comfortable with (70+).
2. Lots of Cores
More cores = more computers. I'm running 3 virtual servers on my machine: one running a SCCM 2012 R2 instance, one as a RODC, and one as a "legacy" server running Server 2008 R2 and SQL Server 2008 R2. And it feels like I'm not even challenging it. These VMs run in the background, constantly, and I have never experienced any slowdown of my regular desktop. So Intel processors generally outperform AMD chips on single or lightly threaded programs? So what? Just overclock the AMD chip a little more to make up the difference plus a little extra. Which brings me to....
Hands down best processor for the money. Period. I got mine on sale for $130. I should have bought 10 of them. That's the same price I paid for the 6350 it replaced. Amazing value.
No problems yet. It runs at 36 degrees "idle", but idle means running 3 VM servers. I have very good air flow, though, including a Corsair H100 push/pull setup. Individual results may vary.
Cons: 1. TDP
Although I haven't had any problems, I can see where someone COULD have problems. I originally had this in a Gigabyte board that didn't have any kind of heatsink on the VRM. I was also uncomfortable with the mere 4 power phases on that board, so I quickly upgraded to the ASUS I'm using today, which has 6 + 2 phases, I believe. The board is everything with this chip. Make sure you have a quality board, because even though the 6350 I replaced had the same 125W TDP, the 8320 simply wants more power. It will run on a low power phase board, but to reach this chip's full potential you really need a more robust board.
Other Thoughts: I've used a variety of processors and, short of some of the newer Xeon chips (Dual X5650 = 6-cores x 2 = 12 x 2 threads = 24 cores!!), the 8320 feels superior to every one. It has just chewed through everything I can throw at it.
There is one item of interest I'd like to mention. When I upgraded my processor from a 6350, the board I was using was a Gigabyte GA-970A-DS3 with a Corsair TX-650 PSU. With the 8320 in there, it caused the system to generate coil whine. When the system was off, it was quite noticeable, and would only stop if I flipped the switch on the PSU.
I had decided to upgrade the motherboard anyway, so, thinking the whine was caused by the TX-650, I upgraded the PSU when I upgrade the motherboard, to a Seasonic Platinum 660XP, which I did not know had a storied history of coil whine problems. The new system produced the same whine, maybe even a little worse. I was quite distraught, until one day I moved the PC to the garage where my servers are, and plugged it into the UPS out there. ZERO whine. Apparently, the main culprit behind the coil whine was the UPS I was using. It was the kind that only kicked in when the power went out; it didn't actively filter the power. Just a note worth mentioning.
This review is from: XIGMATEK dragoon-n422 Aluminum alloy HDT family cooler for RAM module
Pros: These coolers are very effective at keeping my FB-DDR2 5300 RAM at a manageable temperature. The memory in my server gets VERY hot, and the stock heat spreaders don't cut it. I haven't got a cooler on every piece yet, but by installing them in alternating slots I've managed to isolate each heat source and reduce overall temperatures. Plus they look awesome.
Cons: These coolers do NOT fit my FB-DDR2 RAM, due to the protruding ECC module on one side. However, I managed to make them fit with some modifications. These modifications were QUITE involved, so I advise anyone purchasing these for fully buffered RAM to look elsewhere, unless they are comfortable cutting/bending metal to rig these coolers up so they fit over the ECC module. Also, they are quite expensive. Almost as expensive as the RAM itself.
Other Thoughts: I read some other reviews about how they can't fit memory in each slot due to the size of the coolers, but I had no problem. The directions clearly state to alternate orientation on each stick of RAM so the top heatsinks are not all on the same side. However, on my particular board (Intel 5000PSL) there are capacitors right next to the first RAM slot and the bottom matte black part of the cooler prevents the RAM from seating properly. It may work if I attach the cooler slightly higher up on the RAM, but as I stated earlier I had to rig these coolers up to get them to fit my ECC RAM, so taking them off and reattaching them is a multi-hour process that I have yet to attempt.READ FULL REVIEW
