Sandy 2500K Or Asus P8P67 Pro looks to be dying

SimonMaltby I would RMA that CPU mate tomorrow morning and see if you get the same problem on the new CPU if you do it's the motherboard frying the CPU's IMC then.

I think I have exhausted everything I can. It must be either the CPU or the Motherboard.

X58 chipsets would get that problem if they where overclocking and there QPI/DRAM/VTT was to low.
Even at stock it might be your cpu might need 2 notch bumps in QPI voltage, your intergrated memory controller might be weak.

I had that with no base clock overclock. wouldn't worry...
Unless the onboard controller can tell when the BCLK has been pushed past 100, even if its in the past... Not sure thats possible though...

I just ran mine again, it fails on a clokc of 99.8mhz... And thne passes when its spot on the 100.0mhz BCLK... so wouldn't worry

Should ignore that issue intel test will fail on everything unless its all at stock with no energy saving features enabled or speedsteps ect ect.

some motherboard tend to report incorrect base clock fsb speeds wich trip the problem
to get past it just disable baseclock checking in the options.

did you overvolt the memory controller? vccio? or push the memory voltage past 0.5v + vccio voltage as these can destroy cpus?

Memory Voltage: As with LGA1366 and LGA1156 CPUs, keep this value to within 0.5V of the VCCIO voltage to prevent long term damage to the CPU. By default, this is 1.1V, which means the 1.65V used by previous Intel DDR3 memory is still acceptable. However, more recent memory will be rated at 1.5V (or even 1.35V if you choose a low-voltage kit). Increasing the VCCIO voltage obviously gives you more overhead on your memory voltage (remember, add +0.5V at most or risk damaging your CPU).


does 1.1v in bios equal 1.65v to the memory then? as this was confusing me.i understand the concept of it i think so say vccio is 1.1 i think thats what bit tech used then this means memory volts cannot stray past 1.15 or under 1.05? correct?


if this is correct i dont get why the link said it can require a small bump to between 1.15V and 1.2V, depending on the quality of your CPU. Using over 1.2V should only be necessary if you're pushing the CPU toward 5GHz or more. Equally, if you're using the maximum memory multiplier, you will likely require about 1.25V here.


i would be using the max multi if i am running 2133 ram no? so its telling me i will need 1.25 but that making the memory voltages stray over 0.05v from the vccio.



sorry im really knackered atm and i am most likely wrong and dont get it so please let me know thanks! :)

I got this problem once or twice on my Abit IP35 Pro board Q6600

I had to change SATA channels of my DVD drive.

I would try to use only the OS drive and see what happens... On my mobo sata port 4 no long works when i plug in a DVD drive.

Right Simon. If you send me an email. I can sort out an RMA for you and get your board changed :)

I have already sent a webmail for RMA and had a reply from James.
I am ordering a 2600K today and James has asked that I test the CPU in the motherboard first, then RMA which ever is faulty. From my testing I don't think there is any doubt that its the CPU that's failed here.

I'm just waiting for the deals of the day to see if you pop the 2600K on there at a nicer price... hint hint.
(Bother, the deal of the day just went up and no 2600K... I was so sure it would be there today LOL)

Quite a scary thread by all accounts.

If the chips are suffering electromigration 2 days into being used then what does that mean for people who have chips that are stable now but intend to run them that way for months?
 
months? more like years! this pc is now 4 yr old and i plan to sell it on and if it died within a year or two im sure whoever bought it would not be happy at all.

im now thinking of waiting for 1.5v ram, a 2600k in the hope of better silicon and imc and sticking to almost 1.3v max and using a 46 multi.

thats if u can even get 4.6 stable at 1.3 and not fry the thing.another point is the intel video of 4.9GHZ.why show these videos pre release if even 4.7 is killing chips within a week.

something really fishy going on and i really hope its just a bad batch.
 
looks like i am not ordring my sandy then i will be waiting for bulldozer i think or is this down to a bad chip/mobo. but my current rig could be dead....? i might need a new one :@

sucks i was going to get a

2500k
asus P8P67 pro
4gb of xms3

because my athlon rig might be dead but... if this is not lasting a few days let alone a few years!
so hopfly formatting will fix

tbh just 1 post out of the probably 1000s of mobos sold is not that bad. most people will only post on forums if they have a problem, or a question or wanna show off their system ;)

i wouldnt read that there are problems with sandy bridge or their mobos.
