Для чего производители ставят 7-8 слоты на процессор ? Ведь контроллер памяти их не поддерживает.

[TAHUGAVA]

Интересует собственно следующее.

С выходом scalable gen2 на

чипсетах C621 стали все чаще появляться материнские платы с 16 слотами под память. При

этом процессоры которые туда можно установить имеют 6 канальный

контроллер памяти. Как следствие мы получаем не сбалансированную конфигурацию.

(из инструкции к плате X11DPG-SN (https://www.supermicro.com/en/products/

... /X11DPG-SN) мы видим что в использовать

14-16 слотов мы можем только не в сбалансированном режиме) подобные нюансы есть

и на других продуктах, supermicro как пример. 

Никто из менеджеров не может объяснить для чего нужны

дополнительные 4 слота под память в 6 канальном процессоре (недавно вышли

старшие процессоры с 12 каналами, но это отвечает на мой вопрос) .

Hello TAHUGAVA,

Thank you for contacting Intel Customer Support.

Can you please provide us the model of your Intel(R) processor or server board that you are currently using?

Hello !

My task is to build a cluster of GPU servers

For example, I decided to choose the 1029GP-TR platform with a motherboard based on the C621 chipset and Xeon 6230 processors.

The motherboard has 16 memory slots, but the processor has only 6 channel memory.

From the technical documentation for the motherboard we see the following remark « 2 CPUs & 14 DIMMs (Unbalanced: not recommended)» « 2 CPUs & 16 DIMMs"(Unbalanced: not recommended)»

I met this comment not only with supermicro but also with other manufacturers.

Why do manufacturers install 7-8 slots for RAM? if the controller in the scalable / scalable gen 2 series processors has a 6 channel memory finder.

I often have the task of creating a server with a terabyte of RAM, it is preferable to use modules of 64 gigabytes (so much cheaper), but I do not know if it is worth using them in "Unbalanced" mode.

Hello TAHUGAVA,

The Intel® Xeon® Gold 6230 Processor has a max memory size of 1 TB and indeed comes with 6 max memory channels, you can find more information here:

https://ark.intel.com/content/www/us/en/ark/products/192437/intel-xeon-gold-6230-processor-27-5m-cache-2-10-ghz.html

Now, we can not tell why the manufacturer installs 7-8 memory slots, this information should be addressed with the system manufacturer.

Hello!

Please tell us why the Intel Server Board S2600 family of motherboards uses 8 memory slots. (https://www.intel.com/content/dam/support/us/en/documents/server-products/server-boards/Intel_Server_Board_S2600BP_and_Compute_Module_HNS2600BP_Product_Family_TPS.pdf)

The technical documentation does not mention that the mode using all 16 pots is not balanced, but I'm interested in the architectural solution of this approach.

If I use the memory in the format there (16 slots), one of the channels will be 2 times larger than the others, and I will have to make changes to the orchestra.

Hello TAHUGAVA,

Since your question is related to a server board product we are going to continue working on a different case, and we are going to close this thread unless you have more questions on your Xeon processor.
