I contacted Asrock support to find out when a new BIOS will be available for Spectre protection as the latest on the website was still 2.90P. One day later they sent me this P3.00 BIOS and I have confirmed that it contains the new microcode for my 2500K - InSpectre shows my PC as being protected now! If you want to download the new BIOS: https://www.dropbox.com/s/gadngbz0w6a627w/Z77 Extreme4(P3.00)ROM.zip?dl=0 If you don't trust me, feel free to contact Asrock yourself to get this BIOS Hope this helps!
I'm not sure, also at work now. It's not a feature I use - where in the BIOS can I check for you when I get home?
Weird, your quotation shows the image for me even. I've changed the host of the image, does it work now? It shows Slower performance in case it's still not working
it is ok now, thanks the performance impact is still big i without the microcode update noticed it on daily base use, and the update did not fix it, is the price of protection i guess. thank you for the tip my friend
Hello again, can you check please, Please select Boot to Boot Option, and choose Boot Option#1 then select M.2 storage
Sorry for the late reply - I don't see any M.2 options - don't know if it could be due to me not having any M.2 devices in my machine?
Good to know my friend. Spectre is not cool at all. Good job with mobo providers to fix it with a flash.
That board doesn't have M.2/NVMe support at all.. You can see the specs here, no M.2 or NVMe listed. NVMe didn't really become consumer available until around 2014 and that board is from 2012 (2013 was the first consumer released NVMe but 2014 was when it became more common) (https://en.wikipedia.org/wiki/NVM_Express)
