Pros: Great overclocking and quality silicon. Very cool and attractive design. Dual DVI ports.
Run cgminer stable for days at a time at 1040/1600. With 2 cards I'm getting 1.3 Mhash. and i can work on the computer at the same time, browse the web and watch movies, etc with no apparent slowdown.
A lot of people knock the XFX cards but I also own a MSI 280, Asus 7970 and Sapphire 7970 and the XFX get highest hash rates of any 7970 or 280 I have seen and are more stable than the other cards.
Cons: Without extra cooling, the cards were getting pretty warm at full load. The second gpu is basically getting hot air dumped on it by the first cpu went up to 95. I have placed a server grade cooling fan on top of the two cards blowing the hot air out and and temperatures are now 78/84
Also, this is card is not based on the reference 7970 and it only has one bios. It is also voltage locked from what I have read. These factors haven't bothered me because I am happy with the performance. However be careful if you choose to flash these with a non xfx dd bios, because it probably wont work.
Other Thoughts: There was an old 7970 double d gigahertz edition from about a year ago and some people were complaining about vrm termperatures. While I havent measured my vrms with an infrared thermometer yet, I can tell you that these new double Ds from xfx are running super stable.
Also, its not xfx's fault, but the newegg item page says limit 2 rebate per household and the rebate site says limit one. I bought 2 thinking I will get two rebtas and I hope they honor that :) if not I will take it up with newegg.
This review is from: SUPERMICRO MBD-X9DRL-3F-O ATX Server Motherboard Dual LGA 2011 DDR3 1600
Pros: dual lga 2011
6 SATA ports (2 of which are 6Gbps)
8 SAS'/SATA ports
ipmi makes dvd un-needed
Cons: prior to flashing bios and loading drivers, system would blue screen on me and act very quirky - erratic keyboard and mouse response
WARNING, installing windows server 2008 R2 utilizes UEFI, will automagically add windows boot manager as the first startup device in bios. when I flashed from bios ver 1.1 to 1.2, the new bios lost the Windows Boot Manager option. I called support and they suggested repairing the OS installation which didn't work. I had to reload windows from scratch!
cannot get turbo mode to run cpu at 2.5Ghz. CPU is Intel Xeon 2620 -- CPU only runs 2Ghz. already asked support whats up with this and they initially told me to enable turbo in the bios, there is no such option. waiting for updated support response.
Onboard sata / sas intel x600 controllers are gimped to only raid 0, 1 or 1+0 --
even though the motherboard is based on intel x600 chipset, you cannot unlock RAID-5. On intel branded mobos with x600 controller, you can purchase upgrade to RAID-5, 6, 50 or 60. i would have liked to seen this mobo supporting raid-5 unlock. i ended up having to buy a dedicated raid controller so no use for 14 sata ports on the motherboard. what a waste. next time i'll have to buy intel.
ipmi virtual media/remote access can be flakey, its java based and kinda slow
This review is from: NORCO RPC-4216 4U Rackmount Server Case w/16 Hot-Swappable SATA/SAS Drive Bays
Pros: good value for the money -
(16) 3.5" hotswap bays
(2) 5.25" bays, I modded to accept (4) more 3.5" bays
for a grand total of (18) 3TB drives, 54 TB raw, 51TB in raid-5. you could probably fit more if you needed to.
comes with lots of screws and adapter plates for stuff
Cons: Biggest gripe - I bought supposed rails for the RPC-4216 and there were no holes drilled out on the chassis. i had to drill holes myself. i hope that this thing doesn't drop out of the rack. I feel that a rackmount server case should come with rails or at least an insert on the correct item# to purchase.
even after reading the review indicating that YOU WILL CUT YOURSELF. where some heavy duty leather gloves when assembling this. i proceded to nearly cut my finger off removing the fans by the backplane!!!
some holes for routing cables are not well rounded so be careful you can easily sever your cables which could cause a short circuit
Other Thoughts: I wish the backplane had 2 8087 connectors instead of 4, there aren't alot of raid controllers that have 4 8087 ports, i overlooked this and ended up having to buy another raid card.
mobo is an intel x600, cpu xeon 2620, 32gb ram, 10gbe ethernet, 3 raid cards. psu is corsair TX650.
