New Microcode for Broadwell and Haswell CPUs

There are many of us that have "old" Intel CPUs that are wondering when we will see UEFI updates for those Broadwell and Haswell based systems that address Spectre security exploits. Microcode for those is now in the wild and hopefully with motherboard manufacturers to qualify so that those fixes can reach the unwashed masses. Last week Intel pushed out microcode for newer CPUs as well. We do have a list of motherboard websites in this news post that will link you to updated pages that will hopefully show you to your new BIOS. That said, you might not want to jump right in till we see if the Royal Food Taster survives or not, because Intel has not exactly been batting 1000 on this issue.

​
STOP deploying these MCU revs: - Intel recommends to discontinue using these select versions of MCU that were previously released with mitigations for Variant 2 (Spectre) due to system stability issues. - Lines with "***" were previously recommended to discontinue use. Subsequent testing by Intel has determined that these were unaffected by the stability issues and have been re-released without modification.
 
It's probably a 5-20% hit (depending on application) just like the patch for the other CPUs.

BTW, I'm really glad to see this. I've got a building full of 4th gen CPUs. I thought we were screwed.

Still on my 980x, unsure if I'm on secure microcode :/ AMD next

I doubt you'll see one that far back even if it is a relevant processor still.

Edit: Although that link below seems to indicate that they are in pre-production for gulftown, so you never know.

Even if Intel gets around to updating Sandy Bridge, I kinda doubt the Dell that my i5-2400 is sitting in will get a new BIOS at this point. But if it does, is it too much to hope that Dell throws in Ivy Bridge support for good measure?

Hey, a guy can dream... :p
 
I doubt my H67 mobo will get an update from MSI. Due for my 5 year upgrade in 8 months. This might be the excuse I need to make it sooner.
 
I find it interesting that Penryn, Yorkfield, and Wolfdale show up on the list at all, let alone in "planning" phase. Even Lynnfield, Nehalem, and Westmere are in there under "pre-beta". I seriously doubt any motherboard manufacturers will release bios updates for them, but at least Intel seems to be putting some effort into it.

Probably for enterprise customers (providers?) to flash on their legacy hardware.

I can tell you Supermicro isn't updating their systems that far back. My company has several Supermicro servers. We also have 2 Cisco UCS systems that run IB-E chips, and there's no sign of updated BIOS available for them.
 
Still waiting for ASUS X99-DELUXE bios update for this

There's some pretty good people in the Asus forums someone will post a bios with the new code spliced in if ASUS takes too long (or instructions so you can do it yourself if you're not the trusting type).

I'm still waiting for oem manufacturers to release them. As for my personal machines the 2500, 4930k, are screwed.
 
Lenovo updated my TS440 bios right away, turns on they pushed a bad update prior to that one and anyone attempting to upgrade from a certain bios revision ended up with bricked mobos... So, they (after much back and forth) sent out a tech with a replacement board free of charge. So, Haswell/Spectre/Meltdown updates have me waiting a minute for positive reports at least on that hardware.
 
In my opinion, Intel should pay the motherboard vendors to put out updated BIOS files for older motherboards. It’s the very least Intel should do to secure the customers of its older platforms.

It would be a very small drop in Intels ocean, and would go a long way to appease customer feelings.

There is zero reason for them to do this. Intel isn't shy about forced upgrades (Z270 to Z370 comes to mind). Why would they do that when they can sell you a new motherboard and updated CPU? Win/win for both them and the motherboard vendors.
 
This is called passing the buck to mobo manufacturers. None of whom will update anything not current. Tough luck anything older than Haswell and even then most of those upsdates will never get to the motherboards.Intel should be paying board makers, this their screwup, hell they never even fixed the hyperThreading on my Asus laptop Kaby lake and it was bought in July 2017......
 
hmm.. i have an old dual quad core xeon system that did an update yesterday. Wonder if that was it.
 
I think I'll wait a little. Release fix, recall and halt fix.....seems like a clusterfuck at the moment. Who knows wtf is going on.
