Question Asus P8p67 pro & the I7-3770k cpu (10 years old !)

[ooey]

I'm having problems with the two - the CPU refuses to boot, turning off as soon as I turn my PC on. It's an Ivy Bridge CPU 3rd gen? which ASUS say is compatible with my board. As soon as I revert to the Sandy Bridge I5-2500k, the PC works perfectly.

Has anyone been able to get this combination to work? My BIOS is 3602 (the last released for this board). Perhaps I've just got a dud 3770k.

Some have got this combination to work but they haven't said how!

Welcome to the forums, newcomer!

Asus P8p68 pro
Assuming you made a typo with the motherboard's model...

P8Z68-V PRO - Support

www.asus.com

Perhaps you made a typo on the BIOS version? The latest on the site is version 3603 and not 3602. According tot he CPU's support list;

P8Z68-V PRO - Support

www.asus.com

you merely need BIOS version 3203 before you can drop in the processor. Did you inspect the CPU's socket for any bent or broken pins? Inspect the underside of your CPU, take an eraser and clean it off. I meant CPU's underside, not the socket pins on the motherboard.

We're going to need a little more info. When posting a thread of troubleshooting nature, it's customary to include your full system's specs. Please list the specs to your build like so:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
include the age of the PSU apart from it's make and model. BIOS version for your motherboard at this moment of time.

Sorry - board is p8p67 pro. which ASUS says is compatible.

CPU: i7-3770k
CPU cooler: cant remember but its big (Artic something)
Motherboard: ASUS p8p67 pro bios 3602 released on 1/12/2012
Ram: 16gb corsair vengeance DDR3 (listed as compatible) running at 1600mhz
SSD/HDD: Crucial 2TB SSD
GPU: ASUS 1060 Ti 4GB
PSU: Seasonic 750W gold about 5 years old
Chassis:Lian -LI PF8 case
OS: windows 10 pro (up to date)
Monitor: Philips 27"

Using this cpu the pc turns off instantly - whirrs for a second, the cpu error light flashes on and off and then the machine stops). Replacing it with the original I5-2500k I have been using for 10 years makes the pc work perfectly, as it has done for years. Basically I'm just upgrading to the best LGA 1155 CPU I can (from the I5-2500k, which has never given me any trouble).


Pins on CPU & socket are all fine and clean - certainly no problem with the boards socket as I can just slip the 2500k back in and all is fine.


Thanks

The i7 2600 vs the i7 3770 (K) is about the same in real world use.

Your issue is yes there both 1155 socket but the bios for the I7 3770 on the earlier 1155 motherboards does not have the code that the i7 3770 needs to run. You get boot loop no post.

Easy solution flip out CPU to a i7 2600.

Thanks for the reply. Pretty poor of ASUS to say that the board is capable of running it though under that bios isn't it? You would have thought that if they'd tested it it with that board and confirmed its okay then it would work. The Z77 chipset seems to be ideal for the 3770k.

They are sending me a replacement but I guess I'll have to return it for maybe a 2700k.

There have been some that have said they've got this board to run with the 3770k, though not sure how if what you say is true.

I don't actually even get a boot loop, just an immediate shut-down, which is why I thought it might be a faulty cpu. I would have assumed that if it was incompatible the cpu error light would have remained on or something.

Problem is the 2600-2700 doesn't really give much of a boost over the 2500, so if I cant get the 3770k to work i may just upgrade to a modern cpu, board and memory.

I'll probably try to get a Z77 chipset board as i dont really want to upgrade anything else.

Though look at this thread. The OP states that this combination actually works!https://forums.tomshardware.com/threads/older-asus-p8p67-with-i7-3770k-oc-issues.1829555/

Do you have the "Motherboards/P8P67_PRO_REV_31" like in the other post.

I guess you have a replacement 3770K on the way. Drop it in and if it posts cool. If not than you know your next move.

 

[ooey]

Yep. Will post here either way in case it helps someone else. Thanks for your help! I Lets see what happens.

TBH the i2500k is no slouch even in 2024. It's just that the I7-3770k offers a 20-30% improvement to keep the machine more relevant. It's cost effective to keep the same cooler and memory too.
