Which Bios Version should I use?

[sparkythewildcat]

I'm trying to use a friends old mobo to house my new CPU in. As the tags show, it's an i5-3470 paired with an msi Z77A-GD65.

I used his cpu to update the bios, so it would be compatible with my 3rd gen processor. the only issue is, when I updated to the newest version, 10.11, it wouldn't work for some reason. I then tried using the dual bios switch to go back to an older version (10.5) and see if that would work. After that, it made it to bios, but it kept giving me an error saying that there was no bootable device found, even though it was recognizing my HDD in bios and was the first on the boot list, and works perfectly in my current PC. I tried turning off legacy boot and all that stuff. googled for solutions and tried to reformat the HDD, but I don't want to lose the information on it and it wouldn't reformat anyway, for some reason (I can't remember the actual error code it gave me).

 

One thing I did notice, is that when I was in bios, my multiplier was allowing me to change it from auto (stock is 3.6 ghz/36 multiplier) all the way to 42. Now, I tried going back to the previous version (10.11), and it worked. For some reason I was able to boot all the way into windows and the HDD worked perfectly, but upon checking the bios, I noticed that the multiplier was now locked (weird).

 

So my question is this, is there anyone that knows how I could resolve the issue I was getting with the old bios or if there's any bios in-between v10.5 and 10.11 that would allow me to OC still (upon googling, it seems the limit is a 400Mhz OC), without giving me this stupid bootable device error? If not, am I just going to have to flash the bios over and over until I find one?

The Z77 chipset is for the 3rd Gen (codenamed Ivy Bridge) CPUs, not sure why you have to update the BIOS to use a 3rd Gen CPU on it....

wow. how dumb of me then. I guess I assumed, since he had a 2500k and it was from a new build he bought several years back. I'm relatively new to PCs (got into it around skylake release) and I didn't even think to check that.

 

regardless, the issue still stands that with the older bios, it won't boot to windows.

 

Also, I'm not positive if this is the correct forum to post this kind of question on, so pls redirect me if I need to post it elsewhere.
