Thinking about ordering the PlexHD. It seems that most of these X79 motherboard don't actually support RDIMM, only UDIMM even though they claim "ECC" support. This listing specifically states "REG ECC" memory.
Anyone want to take a guess or have any information as to whether this is true?
I have a ton of DDR ECC RDIMM but very few UDIMM and don't relish paying the price for more UDIMMs...
which board? i have an asus p9x79 deluxe and it does support rdimm up to 8gb. i have 2 two of the chinese x79 boards and they both support 16gb rdimm.

if you are going to run i7 like i7-3930k, you need to have udimm. some boards like supermicro x9sra seems to let you get away with udimm ecc, but asus p9x79 wont work with ecc udimm for i7..

X79, C602 and C606 don't have native USB 3. This motherboard in particular comes with a P67 south bridge... You can always had a dumb ass USB 3 controller like in all other X79 motherboards...probably a little better :)

Specifically the "PlexHD" board listed in this post.
Supposedly most of the "cheap chinese x79" boards don't support RDIMM even if they say they do...

well, if they don't include one you have to use a card in the pcie x1. so then you are down to no expansion slots left.

even the "regular" size chinese boards are already bs. but they at least have a few more pcie x1 and one more pcie x16... and also built in usb 3 addon controller.

hmm i guess i could go back again to test even using the 16gb rdimm but i am almost sure that the cheaper chinese board i got for $120 that have 4 ram slots did support rdimm

i am completely certain that runing x79z support rdimm. i tested a 16gb rdimm in it. there are also russian video showing 128gb total ram which i am pretty sure they also use rdimm.

That's the beauty about it...it's the only mini-itx "X79" board that i ever seen.

Technically isnt itx...but with 17X21CM is close enough. It fits just fine on my cooler master elite 110.

I bought this board back in March and paid a lot less for it i believe it was 45usd + shipping. The board you linked while has a different layout seems to me with only 6 chokes that is lower quality.

I don't remember any complaints about the Chinese x79 boards not taking RDIMMs (with e5 processors).

I have two HUANAN x79 v2.49 motherboards. Both are setup with e5's and 4x 8GB RDIMMs. There's been no issue in regards to RDIMMs.

Gave up on these Chinese boards - should known better than to hope. Even built a custom enclosure for it with water cooling.. sigh.

I'm now using refurb HP Z620 workstation boards - works great. 2 x16, 1x8 1x4 (both are open ended), got it for USD$60 and shipping took a few days from eBay.

Good luck to you all, hopefully these next round of X79 boards exceed expectations.

Once upon a time I bought a z800 board, than I had to hack a case to fit it, hack fan connectors, hack the power supply connectors and rewiring them, then after a short while that nasty proprietary motherboard who would refuse to boot with newer cpu's because of some crazy boot lock died and all I was left was a bunch of butchered hardware.

that;s why i recommend lenovo s30. the mb is pretty much oem. that you can use all regular stuffs. too bad s30 is not compatible with cpu like 2696 v2

i still think the runing x79z is one of the better chinese boards even if there is a lot of disappointment with it. It has 8 working ram slots compared to most of the others with only 4 or even 2. this has been verified to take 16gb rdimm with 128gb ram.

no one has verified with 32gb rdimm but maybe it could use that too. can someone with a chinese board verify with 32gb rdimm?

also it has an asmedia sata controller on top of the usual intel one so you get two extra sata port.

i also just verify that i7-3930k works on it but only with udimm, just like all the other boards. i7 will only work with udimm.

thats a good point. luckily the HP 18 pin to 24 pin atx adapter is $5 or less in qty and I'm using water cooling so only CPU fan and linked fan controller for the rad fans

What are the "disappointments"?
I'm thinking either that board (@ $149 USD) or the following @ $93: PlexHD
Granted, I give up one PCI and 4x RAM slots but for a NAS I doubt it'll much matter. The latter is also over $50 USD cheaper.

Thoughts?

EDIT: I have an S2600 board that I can use but have to redrill the case for the standoffs in a supermicro chassis AND have to hack the BDR for the fans and I have no idea where to start with that...

disappointments for runing x79z:

1. cannot get more than two of the pcie x16 to work at once, everyone would be fine with x8x8x8x8, or for me even x8x8x4x4 would be fine, but there has been no success whatsoever at gettting more than two of the pcie x16 to work at once, despite the fact this board has four x16 slots

2. No S3 sleep support

3. MSata slot on the board is just for show. does not work at all.

The positives are

1. 8 rams slots (definitely support up to 128gb ram with 16gb rdimm and maybe more if someone with 32gb rdimm willing to test?),

2. has an extra asmedia sata controller for two more sata ports for total of 8 sata ports,

3. works with just about all the cpus including oem 2696 v2... hasn't tried any es v2 cpu but you really shouldn't be getting v2 es cpu anyway.... also works with i7 cpus using udimm only (all the boards i tested so far will only allow i7 with udimm)

^-yup -- biggest disappointment is lack of all 4 PCI-E x16 working simultaneously.

current pricing for the X79Z-VB10 is $105 + shipping if you order from the mfg

website for direct mfg order? i hope they dont charge like $40 for shipping. then it's just the same as on ebay

Shipping is DHL Express from China so yea it will be $40ish. You can try FedEx, UPS or another carrier which will be slower and cheaper.

The numbers work if you are ordering many boards or doing a group buy, otherwise its not worth the hassle.
