[SOLVED] Changed 4570 to 4770, getting 4 beeps,

[brucepascal]

After changing my 15 4570 to an i7 4770, I get four beeps from my computer... but nothing else.
An old thread tells it might the power supply. Mine has 350 watt and I was told that should be enough..

It runs on an ASRock 85m

What is the bad truth?

Thank you

Very first suggestion, clear CMOS and try to boot.

What is the exact model number of the motherboard?

4 beeps is supposedly system timer failure but really need more info to be sure.

 

[XxDarkMario20xX]

if it four short beeps saying it could be System timer failure.

Answer:The following are AMI BIOS Beep Codes that can occur.

Beep Code	Descriptions
1 short	Memory refresh timer error.
2 short	Parity error.
3 short	Main memory read / write test error.
4 short	System timer failure.
5 short	Process error.
6 short	Keyboard controller BAT test error.
7 short	General exception error.
8 short	Display memory error.
9 short	ROM BIOS checksum error.
10 short	CMOS shutdown Read/Write error.
11 short	Cache Memory bad.

4 Beeps on Post, intermittent problem

So, a little history first. My mobo broke down a couple of months ago giving me 5 short beeps on post. I took it back to the shop and it was repaired. On Saturday, I replaced one of the fans on my radiator and when I touched the tubing, the computer crashed. I tried to re-start a constantly got...

TDP is the same on both processors:

I would try reseating it and carefully look for any bent pins on the socket. If it still doesn't work, install your old processor again and see if it still works.

It is actually the ram channel "b"
Both 4GB ram work in "a" but in "b"
Is there anything I can check?

 

[SamirD]

So ram channels can be affected by the seating of the cpu and bent socket pins. You definitely need to check this now and confirm your old processor still works correctly. Could be a bad cpu as well.

Thank you very much, you were totally correct. I took out the cpu again, and saw a tiny piece of whatever lying in the second row.
I took the aircan and blew it away, put it all back together and... magic !!!!!
Using CPU-Z I checked all the data incl benchmark... and bingo!

I always hat taking off the fan-cooler as two of the plastic sockets are already broken, but it went smoothly.

So, once again, thank you, and everybody else..... you took load off an old man's brain....
