My First DIY NAS Build: Supermicro Technical Support

I was hoping that things with my first DIY NAS build would go smoother. My request for a complete list of the qualified processors for the Supermicro X10SLL-F motherboard used in my first DIY NAS build was clear enough. Milton Cai did me a partial favor in sending along a partial list of those processors. Notably absent from his original list was any mention of the 4th generation Intel Celeron series, as well as all members of the Intel Xeon E3-1200 v3 processors.

I’ve reproduced Milton Cai’s original list, appending the launch date for each product.

Milton Cai’s Original List

G3220 – Q3’13
G3220T – Q3’13
G3420 – Q3’13
G3420T – Q3’13
G3430 – Q3’13
i3-4130 – Q3’13
i3-4130T – Q3’13
i3-4330 – Q3’13
i3-4330T – Q3’13
i3-4340 – Q3’13

Launch dates and additional information on Intel products is always available through Intel’s ARK.

I was surprised to find that the list of qualified processors that I received shows only processors released in Q3’13. Intel continued to release new Haswell processors utilizing socket H3 LGA1150, with support for ECC memory, each quarter (Intel ARK)

I know that there’s a more complete list, so I emailed Supermicro tech support at [email protected] at 2:29PM CST on August 20th:

I’ve called in about my X10SLL-F, updated to BIOS rev 2.0, and issues that I have getting it to POST with Intel Pentium G3258.

I would like to have a most recent CPU compatibility list for this motherboard to help me in selecting an appropriate CPU.

Please send over a full list

I received a response from James Wang at Supermicro at 9:17PM on the same day:

Intel® Xeon® processor E3-1200 v3 and 4th Gen Core i3, Pentium, Celeron processors
Single Socket H3 (LGA 1150)


This response. Words cannot explain how many things is wrong with this. I read it, sighed with exasperation, and reached for the copy of Swanson’s Rules of Management (or The Unwritten Laws of Engineering) that I keep suspended on the side of my desk. I picked it up and gesticulated wildly to bullet point #5:

Viewgraph rule: When something appears on a viewgraph (an overhead transparency), assume the world knows about it, and deal with it accordingly.

This fucking engineer was either trying to be clever, or he is painfully ignorant: the words he relayed are publicly available and were already considered prior my decision to purchase the Supermicro X10SLL-F. Had he taken a moment to read my message before copy-pastaing this tripe to me, he would been better able to address the situation.

I went to sleep, determined to get to the bottom of this. I woke this morning after a brief respite and shot this back to James Wang.

This is not what I asked for. Can you send me a full list of the qualified processors that your lab has tested on the X10SLL-F? I need this in order to select a CPU that fits my requirements.

The information that you sent me is already available to the public on the product information page:

I believe that I was clear in stating that I could not get my Pentium G3258 to POST. This is a processor that was released in Q2’14:

Again – I need the full list of qualified processors for use on the X10SLL-F motherboard. I do not want to purchase another processor only to find out that it does not work.

I sent a similar message to [email protected] as well.

I know, first world problems. Woe is me, the NAS that I hoped to have up and running is doing everything but that. To further complicate my life, I have to attempt communication with engineers.

James fucking Wang.

Update: James Wang came through, sending in a much more populated list. I’ve updated the list of qualified processors for the Supermicro X10SLL-F to reflect the new additions.

I also got a taste of Supermicro’s legendary reputed customer service when I exchanged emails in earnest with James Wang. He states that their lab will qualify CPUs on request. 🙂
