Updated to include official BIOS 73, which adds an option to adjust Read Latency, thereby also giving us one more setting to adjust to fix issues when the full amount of RAM isn't detected.

Updated to include Official BIOS 77 released yesterday, which adds options to adjust the clockskew for the Northbridge (IOH) and two additional options for RAM timing adjustment (tWL and tREF)
tWL = I'm assuming this is a Write Latency adjustment
tREF = Typical Refresh period
For a more indepth understanding of the RAM options, I'd recommend checking out this article from AnandTech: http://www.anandtech.com/show/3851/everything-you-always-wanted-to-know-about-sdram-memory-but-were-afraid-to-ask/
 
I've also removed the recomendations.  Based on what I've seen posted on the boards the past months, it no longer seems necessary to recommend different BIOSes for 32 and 45nm chips.  If anyone disagrees, let me know.

From what I can gather, it seems that most of the problems the 45nm CPU users were having with newer BIOSes were related to not understanding the newer features, like the different turbo options and more extensive RAM timing options.
 
I have the impression that S22D would be the recommended BIOS for 45nm CPU users only because it doesn't have the extra features that are often confusing and misleading, and is therefore a little more fool-proof. 
 
But if there is still enough of a consensus for recommending different BIOSes, I could edit those recomendations back in.

Updated to include Beta BIOS 80, which contains a number of long-awaited option ROM updates and a CPU microcode update.

Updated to include BIOS 82.  Looks like we may finally have proper working VT support.

I have an Alienware Motherboard. If I use this BIOS, it would ruin my BIOS wouldn' it.

I know this is a older post.. but I have looked, I can't see the how too for flashing the bios..
 
I have to admit I have not had to do anything to my board for a long time.. but I just picked up a 980X to replace my showing its age 920..
just looking incase I need to update my bios..
 
Tnks for any and all help in advance

According to EVGATech_LeeM

This is our current schedule for BIOS updates related to these vulnerabilities:
 
By end of this week*: Z170, Z270, Z370, X99, X299, Laptops.
 
Within 1-2 weeks*: X79, W888, Z87, Z97.
 
*Please note that this date is projected, contingent on receiving source code from Intel, and final testing may push the dates back temporarily.
 
At this point, we do not have source code from Intel to update X58, P67, or Z77 motherboards. When/if that becomes available, I'll provide an update.

We don't know when or even if there will be a BIOS update for this motherboard to address the Meltdown & Spectre security vulnerabilities.  I will, however, keep an eye on this and post any updates I hear about.

And now there is this - sorry about being OT, but Intel really needs to get to work on updating older microcode and providing fixes for machines even 10+ years old...

I updated all the download links to point to the new server path, so hopefully they should all work again now.  Let me know if you have any problems with the links.
