If the price was cheaper, I would definitely get it for my QDBW.

As far as I know, the early samples of haswell-ep's only supports DDR3.
I assume that's why it shows memory error q-code when I try to boot it up with DDR4 rams.

I gotta keep my eyes on that mobo.
Thank you.

Depends on the CPU... Check the Intel's ARK for the specific CPU to see the supported memory speeds..

I have a Supermicro X11SPL-F that I'm trying to use with a QJW0 CPU. The problem is the board isn't happy with any memory I use in it, and won't properly POST. I've tried super-gamer-XMP-DDR4-2800 desktop memory, DDR4 registered ECC 2133, and even a single DDR4 registered ECC 2666 stick. Yes, I've tried different slots and resetting the CMOS battery several times. I'm using a standard ATX PSU, if that helps any.

They don't mention 1.35v speeds (motherboard manuals if I understand it correctly note max speed of 1333 mhz for PC3L/1.35v DIMMs)


Oh, I just noticed this is a ES Xeon Discussion board, not General Xeon Discussion

The board posts and works just fine with an actual S-series Bronze 3104. It even likes the AData unregistered non-ECC DDR4-2800 memory.
Max power usage of the CPU is around 30W, oddly enough, as indicated by Core Temp. When going into AVX mode with Prime 95, it stays at 1.3 GHz. I have a power meter which measures barely over 80W coming from the wall under full load.
I haven't tried to put the QJW0 back in yet.

got exactly same board and xeon ql1l xeon works fine with 64GB (8x8 2133 RDIMMs) only thing thats annoying usb detection beeps are, the problem i think you have with qjw0 is that its xeon phi and not scalable that board supports...

So an update for anyone who may be experiencing a similar problem, Bios version P3.70 finally corrects this issue. Memory finally runs at the full speed supported by the CPU.

It's been a while but......

So it seems the Asrock X99 Extreme 3 simply won't support Haswell and Crucial DDR4 Registered Memory running at 1866mhz, despite supporting it just like the E5-1628L v3 does. I've just tested with a genuine (non-ES) E5-1603 v3 with all pads intact and Windows Server absolutely will not boot unless the ram is running at DDR4-1333 or less. Only V4 E5's will boot at DDR4-1866 on this board.

Seems the E5-2628L V3 was running correct for a Haswell Xeon in this board to begin with.... Very very interesting.....

Hi fellas.

First of all, thanks for having generated this interesting and instructive thread.

I'm in the process of building a cheap but powerful workstation for deep learning. I already selected the mainboard, the Asrock x99 OC Formula, since it supports four GPUs, it is shown to consume less than many other x99 products, supports 8 ecc RDIMMs, and should have the microcode needed for ES support (I don't care about overclocking).

Coming to the cpu, I'd like to stay >=10C/20T and above 2.6/2.8 GHz. I'd prefer a QS rather than an ES.

That said, I'd like to ask:

1. Is a QS cpu equal (in terms of compatibility, power draw and functionality) to a retail/oem equivalent?

2. Is there any substantial difference between v3 and v4, apart from TSX-NI? How much will a v4 be faster than a v3 on a basis of same core count/frequency?

3. Is there any substantial difference between e5-46xxv3/v4 and e5-26xxv3/v4? Particularly, in terms of compatibility. Note that this chart: List of Intel Xeon microprocessors - Wikipedia, does not show the usual turbo steps (e.g. 2/3/4/5/6/6/6/6) for 46xx cpus. There is just one turbo frequency. Why? Last but not least, the 46xx tend to be cheaper than their 26xx equivalents. Why?

Thanks! ;)

26xx are for 2 cpu configuration.
46xx are for 4 cpu confirguration.
so you can install 2/4 maximum depends on your mobo.

it's probably because you have to install more cpus in small room? i dunno haha xD

I have purchased this mobo today.

I already got 16gb pc12800r x 4 for 60. so i'll test out with QDBW sample and other xeons.
hope the turbohack work with this mobo as well.

95% of the time is true. Depend on the QS version of the chip.

2. Is there any substantial difference between v3 and v4, apart from TSX-NI? How much will a v4 be faster than a v3 on a basis of same core count/frequency?
If your software does not take advantage the latest instruction set. Then it comes down to cost / benefit.
V4 QS chip cost is much higher than V3 , supply and demand plays a major factor with ebay seller.

3. Supply and demand . Price is cheaper because E5-46xx v3 is not well understood by most user , not well document , too many unknown and risk. I buy E5-46xx v3 chip when it is below $90-$100

I just looked up my ebay purchase record.
Mar 2017, purchased 2 x E5-2683 v3 retail SR1XH for $75 each with Best Offer on Ebay

During the time, E5-2683 v3 was not well understood that would worked well with the all-core-turbo-hack.

It comes down to supply-demand, luck-timing

Interesting. I've obtained an actual Xeon Phi 7210, and the heat spreader is keyed differently when compared to the QJW0 and the Xeon Bronze. Further, when looking at the underside of the 7210, there are four spots where a 4x4 or 4x6 set of pins are missing; this isn't the case with the QJW0 or the Bronze.

Could the QJW0 be early cascade lake then? i have heard there are some samples floating around in china.

The Xeon Phi processors are only compatible with K1SPi and [URL='https://www.supermicro.com/products/motherboard/Xeon_Phi/K1SPE.cfm']K1SPE Supermicro Motherboards.[/URL]

Just want to add that I was one of the buyers from penguinestore using a dual QL1F setup on a SM X11DPHT board. So far so good on my UnRAID setup using VT-X and VT-D. However, I’m only getting 5250 on Cinebench test, not high 5k. I wonder if I’m not optimizing properly or the Turbo isn’t kicking in enough, although I see it jumping to 3.2GHz max on OPPT testing. Using 2x dual rank 64GB ECC LRDIMMs as reference.
Im going to buy this combo QL1F & X11DPH, are you sure QL1F have VT-D Tech??? Thanks!!
