Looking into it a little more, I find that ESPI is helpful with boards that have more than 1 CPU. ASRock C621A WS is a singe CPU board. The CPU I'm using is 8351N, its Scalability is 1S Only, so I'll keep it on LPC.]]> Tue, 21 Mar 2023 00:49:45 +0000 https://forum.asrock.com/forum_posts.asp?TID=25639&PID=104137&title=c621a-ws-board-jumper-settings#104137 https://forum.asrock.com/forum_posts.asp?TID=25639&PID=104133&title=c621a-ws-board-jumper-settings#104133 Author: Xaltar

I'm afraid all I know is that eSPI is newer and was designed to be an improvement
over LPC. In the tech world that doesn't always mean better in every situation.
The fact that there is a jumper to select between the 2 tells me that there may
be situations you will want LPC. My guess is that it would be dependent on use case.

ASRock tech support should be able to give you a better answer. The last time I built
a work station or sever was a very long time ago. ]]> Mon, 20 Mar 2023 15:45:23 +0000 https://forum.asrock.com/forum_posts.asp?TID=25639&PID=104133&title=c621a-ws-board-jumper-settings#104133 https://forum.asrock.com/forum_posts.asp?TID=25639&PID=104127&title=c621a-ws-board-jumper-settings#104127 Author: farpointstation

Anything you could give toward ESPI or LPC as being a choice?]]> Mon, 20 Mar 2023 04:20:35 +0000 https://forum.asrock.com/forum_posts.asp?TID=25639&PID=104127&title=c621a-ws-board-jumper-settings#104127 https://forum.asrock.com/forum_posts.asp?TID=25639&PID=104125&title=c621a-ws-board-jumper-settings#104125 Author: Xaltar

You can open a support ticket with ASRock and inquire. It is possible someone on the
forums here may have an answer for you but WS setups are not common here.

On occasion a manual may have errors, be they outdated info from a previous revision
or typos. If you checked in your hardcopy manual from the product box, compare
it to the one on your product website (pdf). If there is a revision update the
newer copy should be on the site. ]]> Mon, 20 Mar 2023 03:56:07 +0000 https://forum.asrock.com/forum_posts.asp?TID=25639&PID=104125&title=c621a-ws-board-jumper-settings#104125 https://forum.asrock.com/forum_posts.asp?TID=25639&PID=104124&title=c621a-ws-board-jumper-settings#104124 Author: farpointstation

Setting up new ASRock C621A WS. This will be used as a single WS.
-
Jumper 54: ESPI/LPC Selection Jumper, Manual says 1-2 ESPI (Default), my board came with the jumper on 2-3 LPC.
-
Jumper 42: ESPI Flash Sharing Jumper, Manual says 1-2 Master ESPI Flash Sharing (Default), my board has no Jumper.
-
I Will be using Xeon Platinum 8351N CPU. All other Jumpers are in (Default).
-
Question: Should I use ESPI or LPC?
-
This board was unopened sealed, so I'm not sure why these 2 Jumpers were not in Default state.
-
Thanks for any help.
