Solved i5 4440 to i7 4790 swap

December 20, 2019 at 12:31:34
Specs: iPhone
So! I’m about to use a much larger tool on my PC than a Philips screwdriver!

I got a h87i-plus motherboard with an i5 4440. Just purchased an i7 4790, and according to asus it should go right in with no issues.

Took the PC apart, swapped the cpu, new cooling paste, CMOS reset.. when i turn it on, most of the fans are running and the HDD is spinning. But it will not boot!

Switched back to my old i5 and the PC booted right up. So i went to check bios version and i got the latest update and installer that.

Swapped back to the i7, still the same problem. Switched back to my i5 again and here i am..

Any ideas? Got a 650w powersupply, 16gb DDR3 ram, GTX 1060 armor, but i don’t have an i7 prosessor!!

If you updated the BIOS, installed it correctly and still cannot get directly into BIOS set up then we have to conclude that the CPU is bad or has been fried. The only other confirmation is to try installing into another machine with a Z97 chipset and an updated BIOS if possible at all for you. If you can return it for refund or another proven good one then I would do that next. If purchased from a reliable local dealer they should be able to confirm it is good or bad for you.

And upon entering bios once more i looked at the CPU Config. There is one line that says " Limit CPUID Maximum - DISABLED"

Should this one be enabled?

The latest BIOS should support the CPU upgrade but if you expand on the BIOS options there are at least two (1005 & 2.00.02) that specifically say they support the 4th generation CPU's so you can try one of those instead. The 4790 cpu woulf be better on a Z97 chipset but with the correct BIOS is should work.

Are you sure that you are installing the correct amount of thermal compound:

So "upgrading" to an older bios would work?

According to the support page, you need at least BIOS 1005 to support your i7. Personally, I would install BIOS 2003 & be done with it.

The thermal paste MUST be applied correctly using the vertical line method. Never re-use old paste.

FYI...look at a comparison between i5 4440 vs i7 4790:

"Somewhat faster in all kinds of tasks,
Insignificantly higher performance in
games and graphics applications"

Did you purchase it new or used? If used or open box then it might have been someone's experiment gone wrong (over voltage?).

You have not confirmed that you used the correct method of installing the thermal compound.
Could you boot into BIOS set up at all with the CPU installed? If yes then you may just have to get the settings right.
