This review is from: SUPERMICRO MBD-X10SRA-F-O ATX Server Motherboard LGA 2011-3 Intel C612
Pros: - Looks pretty.
- Has room for 3x GPUs. (but no add-on cards)
- The 10x SATA ports are at 90 degrees, making cabling much cleaner.
Cons: Board #1 (new retail package from NewEgg): Complete instability. Random hardware lockups/freezes from 2m to 5h (no Linux kernel panics - just pure lockups). So, I installed Windows 2012R2 thinking it may be Linux. It was greatly exasperated under Windows! Tested each 8GB ram stick one at a time: lockups. Disconnected all devices: lockups. Changed to a different PSU: lockups.
Technical support had several "BETA BIOS's" they wanted me to flash. Hesitant, I tried. The system would never take a "Recovery" SUPER.ROM flash. Technical support couldn't help with this, as they just gave the standard directions. So, I finally just grabbed and modified a normal flash USB image (why a customer has to go the extreme of hacking a bios flash update, goes to show you the level of quality of this product) to get the BETA BIOS to load. It worked for a few reboots; but now, the system hands during the diagnostics. Email support has been great; but, they say to RMA the board.
Extremely hesitant to RMA the board, as this system is in production, I tool the EXTRA time to migrate everything to a very old stable server - and RMA'd the board.
Board #2 (RMA product/not retail package): Better. Took the BIOS flash on first try. After a few days using the existing W2K12R2 system I had on the previous board, it started to show hard lockups again. So I paved the machine and went back to Debian stable. Once every week it would hard lock. Paved the system and went to Ubuntu, same hard locks.
Swapped out memory with KNOWN GOOD 64 GB ECC memory from another server, that was running 1+ year straight with no reboot. Changed SSDs to KNOWN GOOD SSDs. Same hard lock ups about once a week.
Support just keeps sending me beta BIOSes. I flashed one.
Paved the system and went back to W2K12R2. Seemed fairly stable for about 3 weeks - and now the hard locks are happening again. Then they become common, every few days.
Board #3 (RMA product, "personally tested and stable for 1 week" the support rep said): Better than #2, the board is fairly stable.
But as I am writing this, it still hard-locks after several weeks, or every other month.
There are no Windows blue screen dumps to examine - remember, these are all HARD LOCKUPs. Even under Linux. Even tried no Supermicro drivers and just use Windows drivers. Hard lockups. Tried the Windows drivers. Hard lockups. Linux Debian and Ubuntu, hard lockups.
I give up...
DO NOT BUY THIS BOARD.
Other Thoughts: I came back to re-write my previous 1-egg review after 2 RMAs and dozens of Supermicro support tickets.
First, Supermicro Technical Support is really good. I used pure email and they were always very responsive within 4 to 8 hours, even in the middle of the day here in there US where support was mostly overseas. A+
Second, other Supermicro motherboards I have had over the last 20 years are perfectly stable. This "version" is not.
Overall: It was a very hard decision between this board and the X10DAL (the X10DAL allows for all three x16 GPU slots to be used with a single CPU - and has room for 1 additional x8 connected to the PCH!). I disable IPMI due to it's hackable/laughable security.
I went with SuperMicro for their reputation for stability. This product has completely let me down and I advise against it.
This review is from: Startech.Com MDP2DVIS Mini Display Port to Dvi Active Adapter
Pros: - Works with the late 2015 Macbook Pro w/the ATI M370X GPU for triple monitors. (1x this adapter, an older mDP-to-DVI, and an HDMI-to-DVI)
- Decent quality cable, doesn't feel cheap.
Cons: Got a serious color problem - lots of Pinkish hues and color inverts.
I have several mDP-to-DVI adapters (non-active) and they work flawlessly. It's only this adapter.
Will have to return it for an Exchange.
Other Thoughts: I have one of these adapters, an older mDP-to-DVI, and an HDMI-to-DVI connected to 3x DVI-to-HDMI cables driving 3x 24" 120Hz 1080p monitors all via HDMI inputs (the cables I have are DVI-to-HDMI). I do this because I use the DVI inputs of the monitors connected to my monster gaming desktop.
My older 2014 Macbook Pro w/Nvidia GPU can drive all 3 monitors via two standard mDP-to-DVI and one HDMI-to-DVI adapters, no problem. When I got my work's late 2015 Macbook Pro w/ATI M370X, I immediately tried my triple setup only to find out that only two monitors worked.
Read online where this specific "Active" adapter can be used instead. So I picked one up.
It does work, but has a pinkish hue. Will have to return.
Not too disappointed - I have been buying StarTech cables for over a decade and always go to them first. This is the VERY FIRST TIME they have every failed me.
Will return for an exchange.
This review is from: StarTech USB221SS 2 Port 2-to-1 USB 3.0 Peripheral Sharing Switch - USB Powered
Pros: - Easy install, just plug it in and it just works.
- Small and compact. Though, thick USB3 cables are always a bit unwieldy and hard to route.
Cons: - As many others have mentioned, you can see the blue light from the International Space Station orbiting in space.
- It contributes to light pollution of our planet.
- It comes with a radioactive warning label that says to not look directly at the blue light or it will fry your eyeballs.
- You no longer require blue paint to be part of the Blue Man Group.
Other Thoughts: Most of the time it remembers its last setting (e.g. #2 selected) and stays lit/powered on, even when I disconnect my laptop and unplug my desktop (no power to desktop). I think it is getting power from my Hootoo USB3 switch I have it connected to where I distribute 7 devices from this Switch.READ FULL REVIEW
