Having purchased two of Intel Xeon E5-2407 v2 2.4GHz FCLGA1356 processors, I am entirely confused by the fact that socket LGA1356 seems unrecognised in many cases. Is it the same as LGA1366

Having had a dual Xeon LGA771 machine fall over terminally, I am working on rebuilding based on the above processors in a TYAN S7045 (S7045AG2NR) server board.

 

Having noticed along the way that Socket LGA 1356 is not always recognised, this fact is starting to worry me. Have I made the wrong choice? Even within this support community, searching on FCLGA 1356 produced no results. An enquiry to a PSU manufacturer resulted in the answer that the socket was unknown to them.

Is LGA1356 kind of a synonym for socket LGA 1366, which comes up all the time? In regard to a cooling solution, would the 1366 solution fit my LGA 1356 layout. Again, by way of example, the BXSTS100C cooling solution I found to only list LGA 1366 but not LGA 1356.

 

What is going on?

The BIOS of the server motherboard is TYAN S7045 (S7045WGM2NR) supports only the following processors:

All the models belong to the first generation; the version 2 are not compatible with your server board.

In regards the cpu fan, the models available are below:

Passive for rack mount chassis: STS100P (Height:1U, TDP: 95W)

Active versions: STS100C and E97384 (Height:3U, TDP:130W)

Both fan models are compatible with LGA1366 and LGA1356 processor sockets. The fan model BXSTS100C is not recommended for LGA1356.

Hi Mike

Thank you for all the information provided. The good new is you are not claiming that LGA 1356 does not exist.

As to the very bad news you provide. This is where, once more it gets confusing. Your very first link to Tyan when I select my version of that board states under Supported processors: Intel Xeon Processor E5-2400/E5-2400 v2 series processors. Which does not yet contradict my decision for a E5-2407 v2 However, your second link does not include that CPU; which obviously is what you are saying.

So after all the time I had spent trying to sort this out, I guess I will first get back to Tyan and see what they say.

And I thank you for the clarity about the cooling solution.

Hi Mike

To my grand relief, Tyan has advised that the " E5-2407 V2 will work on S7045AG2NR and you have to use BIOS 3.06. The attached file is the test report" Part of the test report includes

So, as I had said, I am much relieved; and this post is for the record in case it is 'found'.

Thank you for your update. I have requested to include the server board model to our compatibility list.
