came with BIOS version suited to Xeon E5-1650 v4
Pros: Worked with v4 Xeon without need to flash the BIOS (as some earlier buyers had to do). The m.2 socket works with m.2 adapter that came with retail boxed Intel 750 Series 2.5" U.2 (M.2 adaptor) 400GB SSD.
Cons: bit pricy. I wish that the recent update that includes a u.2 socket in addition to and m.2 had been available when I ordered this board in spite of it's being yet more pricy.
Overall Review: Did not need to enable hyper-kit feature in order for Intel 750 with m.2 adapter to work in the MB m.2 socket. Benchmarks on the intel 750. were not quite as good as those shown in trade press articles but close enough to give confidence that the interface is working ok. I chose this board in order to be able to use ECC memory and to have an m.2 (or u.2) interface for the system disk .
problem with raid controller
Pros: Works nicely but not in all circumstances.
Cons: The step from firmware level 0002 to 0009 broke compatibility between the M4 and the Areca 1880 raid controller. I discovered this because of the 4 M4's that I bought from NewEgg, 3 were at FW 0002 and worked with the Areca and the 4th was at FW 0009 and when connected to the 1880 at system boot would cause the latter's boot process to hang indefinitely.
Overall Review: A Crucial tech support guy told me that the M4 is not intended as an "enterprise" drive and should not be counted on to be compatible with raid controllers. I hope that the FW 0009 version turns out to be compatible with the Adaptec raid controllers, but I have not found a clear answer to that.
Overall Review: I recommend it. When I first ran memtest86 on my ASUS PRO WS C621-64L SAGE/10G with Xeon W-3235 it did not recognize ECC function of memory. The memtest86 people were kind enough to look at the resulting log file and sent me a private beta that was able to report the ECC function as working. (They have not yet offered a way to simulate memory errors and verify actual correction.)
Pros: generous room, nice space and cable passage slots with edge protectors for cable management, nice external access to four 3.5 in hard disk drives that plug into sockets, nice white color that makes it easier to see what you are doing, glass panels that are classy. There is provision for numerous 2.5 inch SSDs.
Cons: The motherboard I/O panels are recessed about 0.7 inch from the back panel of the case and the part of the back panel between the audio sockets and the PCIe bay interferes a bit with the plug of one of my HDMI cables when it is plugged into the HDMI port of an RTX3090 in slot 1. It is a design flaw that could be fixed at the cost of a revision of the metal stamping tooling.
Overall Review: It is my favorite case at the moment.
it works well if there is only one other blue tooth device in range.
Excellent transmitter for letting users of TV listen via blue tooth headset without bothering others nearby. Good price. Would be nice if it had a little display listing the blue tooth devices in range and allowing you to select the one with which you want to connect. Had trouble syncing to a headset because other blue tooth devices grabbed the connection. Finally succeeded with blue tooth on other nearby devices switched off.
