#1 Stupid Question? Platform ID List. by jwaiv 25.02.2018 23:03

Hello,

Sorry if this is a stupid question but is there a platform ID to socket type translation list available? Failing that could someone tell me how I would translate the Platform ID's in the example below into socket types? For example, which Platform ID would Socket M or Socket 775 be?

| 3 | 6F4 | F5 (0,2,4,5,6,7) | 26 | 2006-03-12 | PRD | 0x1000 | 0x5F3E0 | No |
| 4 | 6F1 | 27 (0,1,2,5) | 12 | 2005-11-29 | PRD | 0x1000 | 0x603E0 | Yes |
| 9 | 6E4 | 20 (5) | 26 | 2005-08-16 | PRD | 0x1000 | 0x65FE0 | Yes |

Thanks!

How the Platform ID bitmask translates into actual sockets (older, LGA775 etc) or platform types (newer, Mobile with PCH, HEDT etc) is not known to the public. We can only assume certain things based on observation. The always applicable rule of thumb is to pick the same CPUID with the same or more (not less) Platform IDs.

Thanks for the reply, is it something Intel keep confidential on purpose or do they just assume that we would have no use for the information? I was looking at https://newsroom.intel.com/wp-content/up...te-guidance.pdf and it shows some of the more modern Platform ID's but was trying to understand the older stuff.

I was to try adding support for a Socket M T7600 (6F6) to an older BIOS, I grabbed the microcode listed below so unless it will cause harm I could just add all four. Looking at the standard BIOS I'm working with my barley educated guess would say cpu006F6_plat20_ver000000D1_2010-10-01_PRD_C3EFBA8F relates to Socket M.

cpu006F6_plat01_ver000000D0_2010-09-30_PRD_B61EC71A
cpu006F6_plat04_ver000000D2_2010-10-01_PRD_6618CFFF
cpu006F6_plat20_ver000000D1_2010-10-01_PRD_C3EFBA8F
cpu006F6_plat10_ver0000004A_2006-06-27_PRD_8A944E2B

The odd thing is despite MCE not listing CPUID 6F6 in the unmodified BIOS a T7600 actually seems to work correctly without issue, no error on boot and seems fine in Windows so it this point its just curiosity.

Thanks!

I assume both but have no way of knowing for sure. It is true that end-users don't really need to know the actual sockets/platform types as long as the aforementioned rule of thumb is followed.

It won't cause any harm, the BIOS will just ignore incompatible CPU microcodes.

I think older CPUs could start without a microcode patch but that is not optimal. Besides, the operating system can load newer microcodes by itself while it initiates. You can see what CPUID and Platform your system requires from within the OS, usually via certain monitoring tools such as AIDA64, HwInfo etc.

That's interesting to know, I always thought the BIOS would give some sort of microcode error. I've looked for an hour or so now and the only sign of a problem I can find is this from the Windows System Event Log:

It might not be related to missing microcode but its worth a shot adding the 6F6 microcode directly, its an old system I'm not too worried about bricking it :)

Yes you should have the compatible microcode patches at the BIOS for the best CPU operation. You can search online to find methods to see from the OS whether a microcode has been loaded, it might be interesting to know that.

#7 RE: Stupid Question? Platform ID List. by jwaiv 26.02.2018 22:02

With a Socket M T7600 installed (6F6) AIDA64 indicates microcode revision D1 is in use, I can only assume that its being applied by Windows 10 in this case because there is no 6F6 microcode of any revision in the BIOS.

#8 RE: Stupid Question? Platform ID List. by lfb6 26.02.2018 22:41

Win10 still loads microcode updates from mcupdate_Genuineintel.dll I don't remember when microsoft announced that they will no longer be updating this file but the latest microcode in it seems to be from April 2017

HelpDat BIOS has posted some info @ocn

Here's a rough generalization for this instance
Platform No. 0 + 1 = LGA 775
Platform No. 2 + 3 = Xeon LGA 771
Platform No. 4 + 5 = LGA 775 (+ some mobile)
Platform No. 6 = Xeon LGA 771
Platform No. 7 = mobile CPUs
