False sensor?
No idea on the CPU stepping but from your pic it looks like Intel is going to release C3 stepping.
So far we only have details on the Z87 chipset stepping which will be launched with C1 stepping. C2 stepping which fixed the USB3.0 problem will be in mass production in mid-August.

Yea,will be similar situation as with P67 series.......

B2=>B3

Z87 with bugged C1 stepping chipsets in launch products.

C1=>C2

Looks like that bro, those early adopters will be forced to exchange their board C1 to C2 stepping starting from Aug two months after launching.
But this time at least we know this issue earlier before release date.

U mean my mobo sensor ? Or might it be BIOS itself ?

Sorry I quoted wrongly i was referring to stasio's post earlier.
Alright, I don't know what's wrong with your PC, if not OCed do you have this boot issue.
What did you mean by PC can't start normally? Can post or not?

Ok, my PC running on stock. LED all lighting up when I switch ON. But when I hit start button, nothings happen. No fan spinning, or even nothing displayed at Q-code.
Just only reseated my CPU, cooler and everything. Now running my mobo outside of my case. Been clearing CMOS around 10 - 15 times n now finally manage to boot. I dont know whats worng with it.

I think there's no better way than RMA it.

Is it possible PSU faulty ? Running on AX650 tho. Maybe should I try with diff PSU before sending out for RMA perhaps ?

no harm swapping out a spare PSU and try just to be certain. but if not psu most probably board already, rma.

i attempted to delid my 3770k yesterday using vise+hammer+wood, but i just cant delid the damn thing. just now went really2 crazy and took a thin blade, delid, booted and whaddaya know, success.






if u noticed the cpu pcb closely, you will see some battle scar the cpu taken during my hammer session.
but the proc still alive and kickin' (im using my pc to type diz post)
Ill post some before/after pics once my liquid ultra arrive in couple of days.

Latest try. With Gigabyte Z77X-D3H + i7 3770K + H100



Still new here.

Like raydenex said, you may try another PSU, RAM, GC, or even CPU if you have spare
Now, two of my 7970s are not working properly, not detected correctly as HD7900 series in device manager, causing sudden shutdown after booting into windows.
I suspect it's either my GC, mobo PCIe slots, or PSU problem.

Good job! We got another success story here.
My chip also has some scratches on PCB, but fortunately it's still alive & rocks.
Pls share some OC results or cooling improvement of the delidded CPU. CLU is the best TIM after CL Pro that I have ever owned. CLU outperforms Arctic MX-4 by 9-10C: Proof
Good luck!

Nice try. But prime95 25.x is kinda old and doesn't have AVX instruction to stress the overclocks accurately.
Without this AVX libraries it's like stressing half of the performance of the Ivy. The latest one is posted in Post#1.

Will try diff PSU later n update here. I hear slow buzzing sound from my PSU , but it is normal right ?

The buzzing noise came from coil whine, which is normal for mos/some PSUs.
I had 4x Corsair AX1200, 2x HX1000, TX750 all suffered from this buzzing sound.
XFX Black 750W and Aerocool Strike X 1100W didn't have this issue.
Can I say this is due to Corsair or OEM poor manufacturing, poor PCB contact, poor soldering & poor glue contact? HAHA

Just tried out with my friend PSU , everything running normal with just a single start button push, with just mobo n CPU . others all I have disconnected. Tried again with my PSU , nothing happen, but the mobo led n start button led light up tho. Quite weird , if my PSU spoilt how can those led light up? Seems my hardware working well with other PSU . should I RMA the PSU now? Lol . I also pening.

Consider yourself lucky already, with just a PSU swap your problem isolated and identified. Imagine if swapping PSU did not solve the problem... then you'll be fiddling with your rig still trying to find the culprit hehe.. Apalagi, send it to RMA bro

Corsair AX650 is OEM manufactured by who? Seasonic?

AX850/AX750/AX65 OEMed by Seasonic: Source

AX1200 is Flextronics: Source

Weird that gold class PSU can easily kaput within few months

Coincidentally, gold price is also dropping worldwide lol.

How about try Platinum PSU?

New overclock. Managed to overclock at 4.5ghz with 1.3V. Vcore still a little high. I believe with a better board my vcore should be lower.
