For this reason, it's worth checking whether you really need to update your BIOS.
Read the release notes of the latest version (and each version back to the one currently installed) to see whether it will add the features you need or fix a problem you're having.
All systems were running Windows 7 Professional x64 and Windows 10 Pro x64.
I cannot guarantee this guide will work with Windows Vista or Windows XP.
Only thing that will happen when you upgrade your BIOS is that it improves stability, adds support for new hardware, improves performance and add a few new feature.
Support for BIOS/MBR boot (Legacy Boot) will still remain.
If for some reason the BIOS upgrade changes from Legacy boot into UEFI boot, you can always enter BIOS setup and switch it back to legacy mode and save the new setting. BIOS v1.7 should improve memory stability, since it seems this particular MB has had some issues with certain RAM.
You will however NOT gain anything by switching to UEFI/GPT, if you only have one instance of Windows installed.
We recommend that you record the original BIOS settings before you modify them.But if I reinstall Windows on SSD, Windows wont load as I need to switch to UEFI first? And as far as installing windows in Legacy mode vs UEFI is a matter of choice, there is no speed gain from UEFI, I always install in Legacy mode, I like 1 partition for windows. ATM taskmanager shows memory at 41%, sometimes CD usage is 100%. What other choice do I have to fix that issue I was facing?little confused about that part Who told you you had to switch to UEFI to get windows booting ? You do not have to flash a Bios to get the memory working, more horse hockey. You can flash your Bios if you want, but that`s not gonna get windows booting if you have a memory issue. MSI forums have told me to switch to UEFI as motherboard BIOS (update) changes how the hardware and memory addressing space is accessed, this has a big influence on Windows". Microsoft tech have suggested silly suggestions like; my current MB does not support latest W/10 creator so I need to roll back Windows to W/10 1605v, Someone said to upgrade RAM (I was gonna spend on it), seems like this suggestion is most understandable...kinda?Before we get started, you are going to need the following tools installed on your workstation: First, download the latest BIOS revisions for each of the models deployed throughout your organization from Dell's support website.Create a new folder in which you will place the downloaded revisions.
