What would you do? Stay 1366 or go 2011/ddr3?

Given the following set of hardware, would you resume going to lga2011/ddr3 or stick with 1366 until moving to DDR4?

lga1366 gear:
- two SMP combos, one slightly damaged (some RAM slots not working)
- several single-processor combos (nagging me due to low RAM but nice for random things)

lga2011 gear:
- 2 pairs of CPUs (1x v1, 1x v2)
- 1 non-posting SMP board with SAS
- 2 new, expensive supermicro HSFs

I have to decide whether I want to ditch the 2011 gear as-is and get more 1366 or whether I move to 2011 (buying one of those cheap 2x2 barebones and one dual 2011 board with lots of I/O).

I originally wanted to move to 2011 to get USB2, faster SATA and SAS onboard. However, now I find myself using PCIe SAS controllers anyway, and PCIe USB3.0 cards, I am forced to use a couple of PCI cards (full height so they would be a pain to use with a PCIe->PCI adapters). For my applications a 3.6 GHz original i7 is very suitable.

On the other hand the money I would get for the 2011 CPUs is low and I have no idea whether the board is broken or I just have some local problem (PSU etc). But boards are expensive outside those 2x2 nonstandard barebones.

Random comments?

Well I feel stupid now.

Socket 2011 boards such as the X9DR3-F actually still have USB 2.0 onboard and only 2 (out of 6) SATA ports are 3.0.

I think it might not be the right platform for me, taking the hint from failure :D

Can't see why you wouldn't go 2011, as this has PCIe 3.0 :) If you are planning to use NVMe, that's def. gonna make a big difference. I've also seen several 2011 boards with USB 3.0. Why are USB speeds so important? External harddrives?

I'd sell it all and jump to 2011 r3 with ddr4 :)

You have pieces of both generations why not unload it all and go with something fresh and new :)
If you can handle ES CPU then you saev a TON of oney... DDR4 16GB are $65-75 all day long, $150-165 for 32GB sticks... plenty RAM.
Magnetic disks are cheap, and continual to drop in price while adding more capacity within the same form factor.

Depending on your needs now get a 2P 2011-r3 motherboard but only populate CPU#1, and expand from there :)

...this reaminds me I still haev some 1366 chassis, and motherboards to sell!! LOL.

The IO performance of 2011 when compared to 1366 is night and day. If you could shell the extra $$ for 2011 setup, it is the way to go.

Last I looked the really cheap RAM is DDR-3 reg. That's why I have so much of it :D

Is DDR4 really that cheap, I mean registered ECC?

Speaking of running a single CPU, this is another reason why I might keep 1366 over 2011 v2. The dual 1366 boards all have all PCIe connected to one CPU. As you say, I am perfectly fine with one CPU as long as I have registered RAM (assuming a decent number of RAM slots per CPU). With 2011 v2 I usually lose two PCIe slots or whereabout, or worse some onboard stuff.

Care to elaborate? Yes, there is PCIe 3.0.

But for a computer that doesn't need highend 3D and uses magnetic disks I don't see how much I would gain. Even 10 GbE wouldn't get me there, I think.

I'm only buying 16GB DIMM's and here DDR4 is a little bit more expensive than DDR3. I am planning to use DDR4, but not before the v5 processors (hoping that v3 will drop). For me, I don't see any real benefit of swapping out to DDR4 at the moment. However, one of the benefits is that the DIMM's of DDR4 is larger than DDR3.. :)

For some reason I am having some serious IO issues with 1366 motherboard with dual IOH chipset. I have 2 system with X8DAH motherboard and both are having some IO issues that I cannot resolved. I ended up replacing them with intel 2011 solutions and no more IO issues.
The Issue I had was primarily with add-on PCI-E 2.0 cards (raid, 10gbe)

I still have a few system running X8DT3 motherboard and they are doing just fine, I am getting twice the performance of the more expansive X8DAH. Nevertheless during benchmark, 2011 solutions io performance trumps both of these setup by alot.

DDR4 16GB is marginally more $ than DDR3.

We're talking $55-65 for DDR3 and $65-75 for DDR4.

That shouldn't be a determining factor.

You can get 32GB DDR4 sticks for $150 - 160$ now too.

I remember a couple months ago being happy I paid $200 for 32GB DDR3 :( Really wish I woul dhave sold al my DDR3 in December and migrated 100% to DDR4 2011r3

Depending on the CPU cores & frequency the 2011-r3 increased IPC may make a slighty slower or slighyl less core still > than 2011 version 1 cpu (which are the super cheap ones). If you can run an ES CPU then your'e even better off too.

Well, I don't need to go 16 GB modules while I am on 1366.

The cheapest RAM right now is 8 GB ECC reg DDR3, which I got for around $10/module recently. On a 12-slot board (common) that gets you 96 GB which is OK unless you run Chrome. Haha. No, it really is a good amount for ZFS, even with some dedup. An 18-slot board is pretty cheap in the 1366 world and gets you 144 GB.

Going Haswell and DDR4 you pay a pretty penny to make it to ~100 GB.

Question, is it really true that LGA 2011 v2 CPUs run in LGA 2011 R/v3 boards? All of them?
No, absolutely not.

V1 & V2 cpus work in Socket 2011 motherboards only (v2 assuming motherboard BIOS supports it).

V3 & V4 cpus work in socket 2011-3 motherboards only (again, v4 assuming motherboard BIOS supports it).

Sorry, mixed up v2 and v3. I always count Nehalem as v1 and then there's an off-by-one error. Never mind.

I have one dual E5-2670 system and it leaves the next fastest system a dual X5670, in the dust. The E5-2670 is vastly superior but yet X5670 chips are still selling at a healthy price. Guess it all boils down to supply and demand.

Really depends on what your needs are. For me, I have a 2011 (ivy) build for vm's and a westmere box for zfs storage.

When looking at the 2011 build a few months back while I could get a matx 2011v3 setup and pay 2-3x more than what I could build for a 2011v2 setup. Partially due to used parts being cheaper on eBay but more so because I already had the DDR3 on hand and had some help acquiring an Ivy processor for cheap.

I'd like to know where to get 8gb ddr3 ecc dimms for $10 a stick, 1600mhz if possible. Best price I've found is $15 which is 50% higher.

Thanks!
