Meltdown and Spectre Patched BIOS for X58 Motherboards

[Regeneration]

Thanks for putting in the work and posting all these bios updates when you really didn’t have to and so many people are asses about it if they don’t like it then they should kick rocks!

I’m about to put together a Gigabyte EX58-UD4P x5680 just wanted to ask if this bios update would work best knowing it’s technically not supported cpu. Have seen others post if using this combo with no issues but have been unable to find out what bios etc they have been using. Thanks

GA-EX58-UD4P should support X5600 series as long as the BIOS is updated to version F11 or newer.

First generation i7 hexacore CPUs share the same CPUID with Xeon X5600 and W3600 series.

Thank you for the quick straightforward response. I took as much from reading the thread but the only stupid question is the one not asked.

Done additional testing on Gigabyte X58 motherboards today. Everything works perfectly.



On another note, it is possible to upgrade to real SATA 3 and even M.2 / NVMe on X58.

On some X58 motherboards, there is a built-in Marvell 9128 SATA 3 controller, but is limited to PCIe x1.

Cheap add-on cards like OWC Accelsior S and SilverStone ECS03 (both powered by ASMedia ASM1062) will give near SATA 3 speeds when installed in a PCIe 2.0 slot (usually PEG slots)



Same goes with SilverStone ECM2x series add-on cards. Clover EFI bootloader can be used to boot from such devices.

@Regeneration Is it possible to install Windows 10 1803 with VT-D enabled on Rampage II Extreme with your patched bios? Thanks

I never experienced the VT-d bug on any of my X58 systems.

There was an errata in some revisions of 5500/5520/X58 related to virtualization. The workaround is to disable interrupt remapping.

I'm using Windows. How do i disable that?

Would be nice to know if this is possible. Anyone with an X58 motherboard managed to get Application Guard to work, mine gets to 30% and fails. Not sure if its because we have to disable vt-d.

Just registered in the forums to thank to you for work.

Successfully updated MSI Big Bang X Power to the patched BIOS. Thank you!

Hi. Have a DFI lanparty DK te3h6 x58 motherboard, asked on bios-mods if it would support Intel xenon x5687 with your bios. I got a answer that it would. Tried today with the xenon cpu. Just black-screen :/. Tried to reset cmos etc. Any advice? I replaced the xenon with another CPU i7 920 that workd like a charm like it did before.

Try to reduce uncore ratio to 1.5 of DDR clock before installing the CPU.

Some X58 motherboards will not POST with X5600 series and uncore above 1.5.

Ok. Can try later. But have you added support for that cpu in this bios update? It is not supported by orginal Dfi bios updates for some reason.
And what is the the difference between the two different bios updates for the same board t3eh6?

T3eH6 and T3eH6-A are different models. The ROMs available in the 1st post support all socket 1366 CPUs.

Is it possible to add this as a modded standard function : uncore ratio to 1.5 of DDR clock. As a " xenon editon" kind of for my motherboard? Because if the cmos reset itself, maby i get a blackscreen again?

 

[1337.]

Btw this is the newest bios from DFI for Lanparty DK T3eh6 x58. Tried to find out if there are any real differences between T3eh6 and T3eh6-A but could not find any info on that. It is newer than the date in your bios file if that date is from DFI. It is the latest release anyways. I used it before i updated to yours.

This ROM has invalid checksums and therefore isn't genuine.

It's a beta or something. I found it on another forum. I don't know.

Would love a Rampage 3 Black Edition bios orz.

Never heard of black edition. Added it to the database.

Hello, I'm using this BIOS patch since the beginning you made that. And thanks for that.
But now we have a new patch from Microsoft KB4482887 developed from Google.
https://www.bleepingcomputer.com/ne...erformance-with-retpoline-spectre-mitigation/
Now i have Retpoline Spectre Mitigation activated and working.
My question its: We need to re-flash the official BIOS back to restore the performance?
Sorry for bad English
*I have a Asus P6X58D-E with 0803 BIOS modded by you.
Thanks for your big work.

 

[Regeneration]

You don't need to reflash the BIOS for retpoline. Spectre mitigation method is controlled by the OS.

 

[NPina]

You are right!
And I already done the tests, without your modded BIOS and with it.
I only made the test with Cinebench r20 3 times each with modded BIOS and 3 times without modded one,
with full shutdown of system and background apps cleaned every time, and i run this cmd "winsat.exe formal -restart"
for each BIOS flash "only 2 times need for this all experiment"
With your modded BIOS I get about around 10pts more, its pointless i know but still better.
And I checked InSpectre.exe in both BIOS they say the same "Meltdown, Spectre protected: YES, Microcode Update Available: YES and Performance: SLOWER,
because microcode it is already there in all test i made with your BIOS patch or not, because I already have retpoline patch applied.
Better with your BIOS my system still protect for all OS's even with old ones.
Thanks for your time to reply me, with so bad question.

sorry for stupid questions....I have a DFI LANParty JR X58-T3H6 ......is this the latest and greatest bios with 6 core support? and why are the bioses being modded? and last how do I go forward in putting this bios on my board?

DFI stopped producing motherboards in 2010. The company also shut down its LanParty website. The DFI BIOS ROMs available here came from 3rd party sources. While the DFI ROMs support Gulftown, it is not guaranteed to work for 100 percent.

 

[portugese pirate]

thank you for answering one of my questions.......where would I find the last bios for that board?

No where. You're better off with the BIOS from the 1st post.
