Summary: I have two of the S5000PSLSATAR boards from another vendor. "R" stands for "revised." This newer model is necessary for use with the 45-nm series 5000 procs, according to an Intel rep. I initially bought the ...SATA model and had to exchange it for ...SATAR.
Pros: Excellent setup.
Cons: Need to flash BIOS per Intel directions to achieve proper cpu fan control.
Summary: As another reviewer mentioned, the older boards are not compatible with the 5400-series until they get a BIOS update. However, the ones we ordered from NewEgg (around October 2008) came with a BIOS that supports the Harpertowns.
Pros: Motherboard is very stable and once it is setup it runs great. We have five of these and none of them have caused us any grief.
Cons: If you have a CD-ROM drive plugged into the SAS ports the BIOS update utility will not boot from the CD. RAM slots could be in a better position for improved airflow to help cool the FB-DIMMs which run rather hot.
Summary: NewEgg couldn't guarantee a replacement had a newer BIOS, so everything had to be returned.
Pros: It'd presumably work with a BIOS upgrade.
Cons: Not compatible with 5400 series ("Harpertown") Intel Xeons under the 6/5/07 BIOS builds (v79), which is what NewEgg shipped January '08. Intel tech support confirmed there's a chicken-and-egg problem. It's impossible to rebuild the BIOS without compatible CPUs and the 5400s aren't compatible unti...
Summary: Takes about 2 minutes to boot up as the system runs an extensive diagnostic of all systems on power up. Everything works well in Suse linux Server/Desktop, though the drivers are a bugger to get going. I'd reccomend this for pro setup only.
Pros: ROCK SOLID STABLE, Room for dual quad core CPU's. Enough Memory space and SAS support (only 4 without a duplexer).
Cons: No FDD controller, but FDD is required for driver disks, needs a resourceful tech to get going. Doesn't come with pre-made disks.
Summary: The long boot time as mentioned by the previous reviewer is so the board can run boot diagnostics. This is how a real server board is supposed to boot and is not a con. It improves server stablity and integrity. A server should not be rebooted regularly, so the delay shouldn't happen often.
Pros: Very stable board, easy setup. Up and running great with dual quad cores and 4GB of RAM.
Cons: Lack of a floppy connect may throw some for a loop. You just have a USB drive to install SATA RAID drivers.
Cons: Takes for ever to boot up - did not time but feels like about 2 minutes. I continue to get BIOS errors despite upgrading the BIOS software and trying many versions of Linux... Red Hat 5, Centos5, Fedora7, Ubuntu..... This motherboard has cost me a ton of time. I'm going to return it.
