Has my i7 bricked?

High quick check chaps, have been having a frustrating relationship with an i7 overclock for the best part of 18 months, giving up on a 4.2hz oc and settling on 3ghz for the last year or so. Even then the thing has been crashing at random times regularly. Yesterday the bloody thing decided to switch itself off entirely and now I cannot even get the mobo to post.

Is there anyway to check if the i7 has bricked without getting another compatible motherboard?

I am running this, I have tried a selection of other components that work in other systems (so its not a graphics or audio card issue)

Intel Core i7 920 D0 Stepping (SLBEJ) 2.66Ghz
Asus Rampage II Extreme Intel X58 (Socket 1366) PCI-Express DDR3 Motherboard
Corsair XMS3 6GB (3x2GB) DDR3 PC3-12800C9 (1600MHz) Tri-Channel (TR3X6G1600C9)

Through a be quiet dark power 850w PSU

The LCD only displays the message pwr_off then counts up when power on is started and the mobo lights up but thats about it. I have tried all the different bios and cmos clearing setting via jumper on the mainboard, so I am really thinking its the chip.

Will running the board sans chip confirm this?

One final point I have been off the hardware scene since I bought this set up and it has basically eaten anything I through at it for two years, is there anything equivelent in the 300-350 quid price range kicking about these days (about half what i paid for the setup originally)?
 
had the cmos out for 10 minutes and depressed the button for a minute (with and without the battery in) also tried another battery. I think there is a jumper or switch to do something else with the cmos but it escapes me.

I have tried all three dimms in various combinations through the various slots on the mobo, not tried another psu but the psu fan is the only one that spins up when powered on.
 
so cpu fan doesnt spin up? i would remove the cmos battery,leave out overnight then in morning try,10mins sometimes isnt long enough,do that first just to eliminate it
 
ok will do that tonight then check back in tomorrow, thanks for the help chaps!

Quick question so I can get my bearings on a possible new build, how does the i5 2500k stock up against the i7 920?

I also seem to be getting the impression that I can get a vastly superior and stable overclock on a 100 quid mobo than the ludicrously expensive ROG ones?
 
yep did the paper clip test first thing, I think the least likely component to go was the be quiet given the ludicrous testing they supposedly put the units through. Which is why I stupidly did not keep a spare psu around because i didnt think it would go but now I cannot test that finally.

Anyway CMOS is out overnight, tomorrow I will give that one last go before I take the chip out and try a chipless boot.

Click to expand...

its about the same upto 4.2ghz as the 920,just overclocks higher and runs cooler,wait for ivy bridge if i were you oh and 2500k wont have multithreading
 
possibly, but waiting till april for a new gaming rig when i am half way through skyrim... and i will need a new mobo for that anyway. Though a bit of prodding shows me I can get a motherboard that does all the whizzbang sillyness of the ASUS Rog series for no money and overclocks like a piece of ****. And will be ivybridge compatible, it's rather tempting at the moment. So if my i7 920 is dead a i7 1366 socket replacement seems less worthwhile then a less annoying mortherboard and equally good (if not slightly better) 2nd gen i-series chip for the lga1155 mobos.

How much are sandybridge prices going to crash by come april?

Right chaps tried the CMOS overnight trick and no dice,

did the psu power check again and the thing spins up the psu fan (but no system fans?)
 
anyway you could borrow another psu to test with? even brand new psu's can be faulty or die,do the mb lights light up?
 
yep the case fan lights as well, the navigation buttons light up (start etc.) the other mobo lights don't though - hdd etc.

Tried booting without the CPU in, no joy.
 
Motherboard I'd also more likely to brick than the CPU. Mine was randomly resetting lots until I replaced it.
 
I had the same issue last April. I7 920 on RIIE. Ended up buying a 950 and RIIIE only to find out its a corrupted bios.:(

Try moving the BIOS jumper to Bios 1. boot from it, then re-flash the other Bios.
 
sadly tried that at the start, will not boot from any jumper combination

ASUS tech support got back to me stating that the pwr_off posting most likely meant an rma (annoyingly my board was just outside of that).

Going to say taataa to the 920 and get myself a cheep 1156 chip and mobo (probs the Asus P8Z68-V GEN3 and i5 3.3 2500k) to tide myself over until the new intels come out... then down in price.

Thanks for all the help people!
