i like the gtx 950 since it has more video outputs up to 3 dp1.2 and 1 hdmi 2 and 1 dvi compared to 1050..

400w is pretty close to the limit for running these systems.... not sure if thats enough for mining like poutnik said

but $30 is cheap for a case with psu included.

i probably would pay a little more for this one:

NEW Intel X79 Motherboard LGA 2011 ATX DDR3 or ECC / REG USB 3.0 SLI WiFi + OC | eBay

has more ram slots and pci-e

depend on how much storage you really need, i was thinking of going down to 128GB and upgrade to e5-1650 v1 for just slightly more than 1620v2 but gives you significantly more threaded performance. but e5-1650 v1 is not on that cpu list for that board so i wonder if it will support it.

I thought I saw some videos of Russian youtubers running the E5-1650 V1 with that motherboard.

Edit: Found it. Just use e5-1650 as a search term.

e5-1650 - YouTube

There's more than a few videos with the Hunan X79 motherboard and the E5-1650.

my guess is the v1's would work. I will probably pick one of these up and see how it goes. The traditional x79 retail boards are over $200 and don't take rdimm's

Not to mention that the mid and upper/flagship X79 motherboards still command such a price premium that even X99 motherboards are cheaper. Take a look at the prices that ROG ASUS X79 motherboards go for especially the Rampage IV flagships even used. I heard in 2015 their prices plummeted but it seems that since 2016 they have largely remained the same. Even the P9X79 can be seen at a premium (not to mention the X79 Deluxe).

if it wasn't for the fact that i am already knee deep into a dual 2686 v3 build, i might try this too...maybe later...lol.. it would actually be faster than my old trusty i7-2600k i am still using daily...

it would definitely be a real step up from my 955 x4 athlon, the other computer that i am using...lol..

I have couple of two Intel DX79SI board running with I7-3960x. couple of MSI X79 boards as well.

I love these boards, they are really versatile especially with the price of DDR4 ram.

Shot me an offer.

Did they ever update the bios for Ivy-E for the DX79SI? Again, the only downside to these boards are not being able to use cheap RDIMM's.

I don't follow the Intel DX79 board progress much.
They are running I7-3960x as my gaming machines ( I don't game now ).

I have a large stock of DDR3 desktop memory on-hand. So I don't know about RDIMM.

Nope. Intel never offered Ivy Bridge-E/EP bios updates for their branded motherboards.

Ivy Bridge-E bios update for DX79SI

Guys,

We are not planning to enable backwards compatibility between the Intel® Desktop Boards based on the Intel® X79 Express Chipset and the Intel® Ivy Bridge-E processor family.

Regards.
Core i7-4960X Ivy Bridge-E review: Intel's Great Limp Forward - Page 2 of 3 - ExtremeTech

One of the issues swirling around the Core i7-4960X launch is whether or not the chip will be a drop-in replacement for most people. If you own an Intel board, the answer is “no.” Motherboards from third-party vendors like Asus, Gigabyte, and MSI should be fine with microcode updates, but Intel has decided not to extend this functionality to its own products. The DX79TO, DX79SI, and DX79SR will not be receiving the necessary microcode updates to enable Ivy Bridge-E.

To put it bluntly, that’s a crock. For 15 years, Intel cultivated a reputation for itself as providing a stable product with full support for any additional products that launched for that socket. We knew Intel was leaving the motherboard business, but expected that the company would continue to support its products. We’ve confirmed that the Ivy Bridge 4960X won’t run in an Intel DX79SI, even though a BIOS update was released for that motherboard as recently as last month.
That's why those boards are usually cheaper and easier to find. Having no support for Ivy Bridge-E/EP is a big-downside in my opinion when all the other motherboard manufacturers had support with a simple bios update.

That sucks, I have had real good luck with intel boards in the past being extremely stable and reliable.
I agree some of their X58 motherboards (the later versions with 1st gen USB3 3rd party controllers) were great motherboards. Even their older LGA775 motherboards were great. It doesn't make any sense why they would release bios updates for their X79 motherboards and not include microcode support for Ivy Bridge-E/EP. That's a big issue in my opinion because Ivy Bridge-EP processors are coming onto the market at cheaper prices and you can only use Sandy Bridge-E/EP. I don't think I've seen an explanation of why they did it that way.

crazy thing is x5650 is not that much slower than e5-1650 v1... x5650 goes for less than $20 per cpu

That really depends. X5650 is Westmere architecture and 1650 V1 is a Xeon version of the 3930K (Sandy Bridge-E/EP). Using Anandtech's review for the 5960X and IPC improvements going from a i7 990X to a 3960X is at least a 17% average improvement which is quite impressive for the same 32nm node architectural change. Especially if you compare that with the smaller incremental improvements from SB-E to IVB-E or to HW-E.

i wonder if this MB will take OEM chips like 2696 v2 that my intel s2600cp is refusing to take.

I haven't tried, but they are reported to be more CPU tolerant. In the Russian world (where these Chinese boards are more prevalent), it's reported to support ES/QS chips too. And usually the answers from Russian users of the boards are more precise than those from the sellers. You might give it a try...

I'm fairly certain it will work. I don't know about ES but I'm sure it will work as long as it is a QS or a production processor.

not cheap chinese MB, but what does everyone think about this?

708615-001 HP Z420 SYSTEM BOARD | eBay

HP Z420 MB. this one is supposed to be the higher number part with the boot block allowing for v2 cpu. it does have the 18 pin main power connector. which there is several adaptor cables you can get....

anyone successfully got one of these boards to work in a regular atx case and psu with the adaptor cable? the only other issue is that this might not support oem cpu like 2696 v2 ? wondering if anyone tried...

sucks there seems to be no avail i/o plate since that's part of the case unless someone found a custom made one somewhere else

I have a Z420 complete system, have not tried building a new one around the board. And definitely would not do it - too much hassle, too many problems to solve:

* PSU adapter cable (easy to solve)
* fans have non-standard pins
* count on no E5-v2 support unless you are 100% certain about the BIOS boot block date (It's not user updatable, build in feature of the board)

If you don't want to trust the chinese X79 boards (and I understand that even though I'm very happy with my X79 - it's running 24/7 doing mining for the past 5months), get a SuperMicro board.
