Muhammad Uwais · Oct 9, 2021

Hello.I'm using a computer with BIOS A03. If I want to upgrade to a new processor like AMD, do I need to update the BIOS? how do I update it?And if I update the BIOS, does it corrupt and slows down my computer.I'm using a Dell Optiplex 2009 version, Optiplex 760I'm afraid updating my BIOS may corrupt my computer. Thank You. * Original title: How do I update BIOS?

Intel Gives Core i3 and Core i5 Dual-Core Processors K0 Stepping Update

Intel is giving some existing 32 nm "Clarkdale" based Core i3 and Core i5 processors an update. The processors will transition to the new K0 stepping from the existing C2 stepping. The parts that will be made on the K0 silicon are Core i3 models 530 (new sSPEC: SLBX7), 540 (new sSPEC: SLBTD) and Core i5 models 650 (new sSPEC: SLBTJ), 660/661 (SLBTK/SLBTB), 670 (SLBTL). Newer and upcoming models such as the i3-550, i3-560, i5-665K, and i5-680 are already being built on the K0 stepping die. Motherboards will require a BIOS update to support the new K0 stepping processors.

The K0 stepping change includes the following highlights:

New S-spec and MM numbers for the converting products

Extended CPUID will change from 0x00020652 to 0x00020655

Host RevID will change from 0x12 to 0x18

K0 stepping package is pin compatible with C2 stepping package

Adds Processor Context ID (PCID) support

The revised older SKUs that are built on K0 stepping will be market-available by October 16.

Processor upgrade

The process is just as bobkn described.

To avoid problems with the flash, do the following:

Download the 3 files you need, and save them to an easy to find location - Desktop, etc. You will need BIOS version F32, BIOS version F50, and the EC FW update utility.

You will need a blank USB thumb drive (nothing on it). The thumb drive needs to be formatted FAT32 (the standard for most thumb drives), not NTFS.

Step one is to flash to BIOS F32, so copy the F32 BIOS file to the thumb drive. Only the file, not the entire folder if it comes zipped up.

Perform the Flash as directed in the instructions.

When the flash is done, don't forget to do the last step: "Load Optimized Defaults" .

Then Install the EC FW update utility. Always best to restart the PC after the installation.

Then delete the F32 BIOS from the flash drive and copy over the F50 Bios to it.

Then install the F50 BIOS.

And then you are ready to upgrade the processor.

Note: always a good idea, after installing the processor and entering BIOS to check it out, to Load Optimized Defaults again, then Save & Exit.
Make any BIOS customizations after you have tested the system and Windows and all is good.

An Update on AMD Processor Security for Spectre and Meltdown

The public disclosure on January 3rd that multiple research teams had discovered security issues related to how modern microprocessors handle speculative execution has brought to the forefront the constant vigilance needed to protect and secure data. These threats seek to circumvent the microprocessor architecture controls that preserve secure data.

At AMD, security is our top priority and we are continually working to ensure the safety of our users as new risks arise. As a part of that vigilance, I wanted to update the community on our actions to address the situation.

Google Project Zero (GPZ) Variant 1 (Bounds Check Bypass or Spectre) is applicable to AMD processors.

We believe this threat can be contained with an operating system (OS) patch and we have been working with OS providers to address this issue.

Microsoft is distributing patches for the majority of AMD systems now. We are working closely with them to correct an issue that paused the distribution of patches for some older AMD processors (AMD Opteron, Athlon and AMD Turion X2 Ultra families) earlier this week. We expect this issue to be corrected shortly and Microsoft should resume updates for these older processors by next week. For the latest details, please see Microsoft’s website.

Linux vendors are also rolling out patches across AMD products now.

GPZ Variant 2 (Branch Target Injection or Spectre) is applicable to AMD processors.

While we believe that AMD’s processor architectures make it difficult to exploit Variant 2, we continue to work closely with the industry on this threat. We have defined additional steps through a combination of processor microcode updates and OS patches that we will make available to AMD customers and partners to further mitigate the threat.

AMD will make optional microcode updates available to our customers and partners for Ryzen and EPYC processors starting this week. We expect to make updates available for our previous generation products over the coming weeks. These software updates will be provided by system providers and OS vendors; please check with your supplier for the latest information on the available option for your configuration and requirements.

Linux vendors have begun to roll out OS patches for AMD systems, and we are working closely with Microsoft on the timing for distributing their patches. We are also engaging closely with the Linux community on development of “return trampoline” (Retpoline) software mitigations.

GPZ Variant 3 (Rogue Data Cache Load or Meltdown) is not applicable to AMD processors.

We believe AMD processors are not susceptible due to our use of privilege level protections within paging architecture and no mitigation is required.

There have also been questions about GPU architectures. AMD Radeon GPU architectures do not use speculative execution and thus are not susceptible to these threats.

We will provide further updates as appropriate on this site as AMD and the industry continue our collaborative work to develop mitigation solutions to protect users from these latest security threats.

Senior Vice President and Chief Technology Officer
