I have i5-4430 from the factory, i've tried to update my bios to P21.A2. I have no screen output if I install i7-4790. What can I do? Or even it is not compatible?

    You need to update the bios first to version P12.A2 as this bios update allows the i7 cpu's to work and be compatible. The oem i54430 is only 88% compatible with the i7-4790 cpu as far as the CPU-UPGRADE site is concerned who has a list of tested and compatible upgrades of cpu's, so that could be a factor of why the i7-4790 cpu is not compatible.

    Try the Core i7-4771 cpu as this cpu is 99% upgradable and tested to be compatible from the oem i5-4430 cpu to the i7-4771 cpu which is better and more powerful cpu also. The Veriton X4630G desktop should work 100% with the i7 upgrade and imo you should upgrade the bios before the i7-xxxx will work. Good luck and hope this helps you out.

    Thanks for your reply!

    I’ve tried to update my bios to P12.A2, however, it didn’t work. The administrator cmd page would just crash since I started the update in win10 system. It would show the error “ROM size does not match the existing BIOS size. Can't flash BIOS” even I tried in win7 system. I can’t tell if there is an mistake during the update or my x4360g can’t compatible with P12.A2.

    Are you following the bios flash guide titled "System BIOS Update SOP for Windows v2.01" that is provided within the bios version P12.A2. You must be doing something wrong as the bios flash guide should work 100% and get updated to this new version, get a technician to flash this bios for you, your bios chip could be faulty and that is why it can't be updated and you need to get either Acer Tech Support or a technician in your area that has a proper bios reprograming tools to flash this new bios for you, as that is why the new i7 cpu is not working with your mainboard.

    The P1x BIOS versions are for the Windows 7 motherboards, the P2x BIOS versions are for the Windows 8 motherboard. They can't be swapped since the CMOS chips are different between the two motherboard types. Which BIOS version do you have now?

    Err...I have a similar problem. I am running Windows 10 on my L4630G, would like to use a i7 4770.

    Which bios would i use then? I did flash P21.B2 successfully (was originally on P21.A1) so I went with P21 instead of P11.

    It refuse to boot up tho. The case fan jiggles every time I press power button but it doesn't fully spin and no power on light.

    I can drop the original 4440 back in and a 4460S, both boots up ok.

    Is it likely a CPU issue (and in 2024...the 4th gen CPUs are all second maybe third hand already. Or just BIOS?

    It's most likely an issue with the CPU itself. Those are ten years old now…

    gino- were you able to make the i7 4790 processor work in your machine? Like you, I have a Veriton x4630G with a i7 4770 processor and bios p21.A2. I would think the 4790 would be a drop-in upgrade but it won't boot. (I was easily able to upgrade to Windows 11, and it runs great). I don't think StevenGen is correct to try and flash bios p12.A2, because according to Billsey, that bios is for a different motherboard than we have. I'm afraid to brick the machine by trying it. Does anyone have any thoughts on why the 4790 is not a drop-in replacement? Would it have anything to do with the Windows 11 upgrade? Appreciate anyone's advice to solve this! jb

    No idea what you had to do to get Windows 11 running on a 4th gen system, but I don't image the difference between a 4770 and 4790 would affect it…

    Easy as pie- I did the registry change that is supported by Microsoft before I did this command prompt. Works flawlessly in just a few minutes, and the Veriton seems to run better on Windows 11. I was given a 4790 as a gift, and thought I'd try it- But do you agree the P12.A2 isn't the right bios for my machine, or should I hold my breath and try to flash it? Appreciate your advice! jb

    That is not supported by Microsoft, and from what I understand they have been working toward configuring the Windows update process to block those machines that have been setup using the server option. As for the BIOS, you have to look first at which BIOS version you have installed currently. It should either be the W7 version without UEFI support or the W8 version with UEFI. Since you are currently running P21.A2 we know it's UEFI and any P1x BIOS would be incorrect.

    Thanks for your expertise- Much appreciated. I'm sure some guys smarter-than-me will figure a work-around if they do find a way to block updates. In the meantime, this machine works much better than when it was brand new. All the best! jb
