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 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 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.

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.

Are you sure bios is on 3602?

The cpu does work on the p8p67 series, something else is going on.

Older Asus P8P67 with i7 3770K OC issues

Hello, I used to have an i5 2500K with this motherboard http://www.asus.com/Motherboards/P8P67_PRO_REV_31/, I have since upgraded to a newer i7 3770K last fall (updated bios for it). It has worked great for games up until i started playing newer releases and Alpha/Beta tests; ArcheAge, ESO...

yep - 3602

Actually I've checked and my board is only rev 3.0. However, it seems to be only the USB controller that is different for reasons of cost. The BIOS for both revisions are 3602 but the rev 3.1 one seems to be a slightly different size. That might be the problem. We will see!

The board revisions are very minor I think. ASUS have stated that this CPU (I7-3770k) WILL work with the P67 series chipset, as you have said, but the slight revision might be enough to trip it up I suppose.

It must be the CPU change though, because the I5-2500k has run smoothly since I got it in 2012.

The good thing is I bought the cpu from CEX here in the UK, so I have the option to return it if I can't get it to work (or if I can't get a decent z77 board off ebay).

Yes - Ivy bridge CPUs don't work on this board. I got an ASUS P8Z77 instead (ebay bargain - board, i7-2600k & 32gb memory for £40). Surprised someone got it to run on a rev 3.1 board though.
