DISCLAIMER: READ CAREFULLY IF YOU USE AN ASUS P67 Motherboard. First things first: This thread is NOT meant to scare any ASUS P67 users, but rather to inform them of what happened to me TWICE in 10 months, and let them know that we might do best to exercise caution when using these motherboards, WHETHER we overclock or not. Now, to the "story", I will try to present in a timeline sort of way, so it's better to understand, and not just a wall of text. MY HARDWARE AT THE TIME OF FIRST DEATH: CPU: i7 2600k @ 4.2 | 1.224v LOAD. MOBO: ASUS P8P67 Evo (non-B3) PSU: NOX Urano 700w RAM: 4GB |2x2gb| Kingston HyperX 1600mhz @ 1.65v GPU: Sapphire HD 6870 1GB DDR5. TIMELINE OF EVENTS - 1st DEATH (P8P67 Evo + 2600K) Thread on overclock.net about it. Late January 2011: I upgrade to Sandy Bridge. I buy a P67 Evo, a 2600K and 4GB of Kingston HyperX 1600 1.65 (more on this later); From January until February 11th, all works fine and dandy. Sig rig sits at a comfortable and perfectly safe OC @ 4.2ghz with 1.224v under MAX LOAD. All other voltages on AUTO, and RAM was running @ 1.55v 1600mhz (they were 1.65v, but stable at 1.55v); February 11th: My computer just shuts down while playing CS 1.6. Out of the blue. Never to turn on again. Symptoms: PC won't turn on at all, fans spin for a fraction of a second when power button is pressed. Nothing else happens. All parts are taken to the store, where the motherboard is deemed dead. I still kept my first 2600K, because no one, not even me, suspected of anything else other than a faulty mobo AFTER THE PSU was tested and deemed OK. BTW, that PSU still works on my secondary PC since february. 100%. February-March: During this time, I was without a system until late March, when the B3 Revision mobos started rolling out. I still had my netbook though, but it was a pain to use as a main for 2 months. Fast forward to late March, (30th, I believe), my new B3 EVO arrives... ... Only to discover that the previous P67 EVO had killed the CPU as well. I couldn't find a board to test the CPU on during the recall. Bear that in mind. So I only found out my 2600k was dead when my new mobo came. [*] Late march: my 2600K goes through RMA, I got a new one in about a week. All is good again. Early April: I buy a BRAND NEW Corsair TX650, just to be extra cautios. Might as well invest on a decent PSU once and for all, right? IMPORTANT REMINDER: This 1st death occured during the painstakingly long Intel mobo chipset recall. I was without a new motherboard for almost 2 months. Now, we move on to the second death.... MY HARDWARE AT THE TIME OF SECOND DEATH: CPU: i7 2600k @ 4.2ghz | 1.248v LOAD MOBO: ASUS P8P67 Evo B3 PSU: Corsair TX650w RAM: 8GB |2x2gb| +|2x2gb| Kingston HyperX 1600mhz @ 1.65v GPU: Sapphire HD 6870 1GB DDR5. TIMELINE OF EVENTS - 2nd DEATH (P8P67 Evo B3 + 2600K) My thread here on Techpowerup about it. And on Xtremesystems too. From Late March / Early April, everything is absolutely fine and dandy. Sig Rig working wonderfully without a single hiccup. Fast forward to late October: BAM! Dies again. This time, not during CS 1.6, but during a 3Dmark Vantage run. Pc shuts down in the same manner as the first time, out of nowhere. Fans do the typical split second spin, and then nothing. Only death. Take PC to my store again: ANOTHER DEAD MOBO and CPU. In the meantime, I swap my RAM to 1.5v DIMMs and with XMP profiles. My previous HyperX ones didn't. Right Now (November 17th): Sig Rig has been working fine, for now. ALL is at stock now. I won't touch anything else on this motherboard. MY CURRENT HARDWARE: CPU: i7 2600k @ STOCK. MOBO: ASUS P8P67 Evo B3, EVERYTHING @ stock. PSU: Corsair TX650w RAM: 8GB |4x2gb| G.Skill RipJawsX 1600mhz @ 1.5v XMP GPU: Sapphire HD 6870 1GB DDR5. BOTTOM LINE: 1st DEATH: In less than a month, my first P67 Evo dies and takes the CPU with it. 2nd DEATH: This time, it took 6 months to die... but it still died. Will it happen a third time? I don't know, but I'm afraid, to be completely honest. One last thing, and this is, IMO, the most important thing: I just couldn't let this go. I KNEW I wasn't doing anything wrong and yet, my hardware had died on me TWICE, under the same mysterious circumstances. I consider myself an experienced Overclocker, and while at first I though "Oh crap, what am I doing wrong... I hardly believe it's me afterall. It must be something in the hardware. So I decided to digg in as deep as I could... and while I'm NOT listing EVERY case I found, I'm posting the most relevant ones. And... ...It's not happening to just me. In case you were wondering if I'm must be in fact doing something wrong, well, there's been a few "deaths" scattered around the web. The problem is exactly the same: PC shuts down, won't turn on again. in the end, DEAD MOBO and CPU. Compiled list of ASUS P67 deaths, that also killed the CPU: (Some weren't even overclocking, others were gaming, others were idle). http://vip.asus.com/forum/view.aspx...7&id=20110426021716988&page=1&SLanguage=en-us http://hardforum.com/showthread.php?t=1593874 http://www.benchtec.co.uk/forums/threads/8115-P8P67-Rev3-Woes....... http://adrenaline.uol.com.br/forum/.../369578-asus-p8p67-placa-mae-bomba-fujam.html http://www.overclock.net/t/1014337/dead-p8p67-pro-18-days-old http://www.overclock.net/t/1042932/p8p67-dead-question-about-upgrade http://communities.intel.com/thread/20868 PART II http://www.xtremesystems.org/forums...ssion-thread&p=4816984&viewfull=1#post4816984 http://www.xtremesystems.org/forums...ssion-thread&p=4817920&viewfull=1#post4817920 http://forums.overclockers.co.uk/showthread.php?p=18903994 http://www.phforums.co.za/f14/i72600k-asus-p8p67-dying-63481/ https://vip.asus.com/forum/view.asp...board_id=1&model=P8P67&page=1&SLanguage=en-us http://www.xtremesystems.org/forums...ssion-thread&p=4970457&viewfull=1#post4970457 And... You know what the Icing on the Cake is? Just Google : "p8p67 dead", if you have google suggestion ON, you will see google automatically filling in your search. See what it does? There must be a WHOLE lot of more cases, for Google to have it on auto-suggest already. CONCLUSION In the end guys, this is NOT a thread against ASUS. To be honest, they are by far, my only choice for motherboards and I love ASUS stuff. I have 2 notebooks and netbooks from them only., but after seeing my stuff die for no apparent reason, I'm scared.
