Intel i5 2500k 3 active core 1 core failed. Dual channel memory setup failed to post on working non dual channel

Hi Support Team,

Recently i encountered the I5 2500k failed to boot windows with only MCE error. Even Linux have kernel panic.

Once i replaced CPU cooler suspecting the cooling issue could be one of the cause but even though its not as it was stable 40-50 deg.

But i was seaching for forums and reply and many replied replacing the cpu which is no option for me as i am out of the 3 year std . Even though tuning performance package available i am away from 3 year period.

I cant get a replacement now.

When i got the replacement CORSAIR h100i v2 liquid cooler . I tried with 2 cores bang it worked and i restore the windows 10 image and rebooted with 3 cores and bang it worked again.

Now with 4 core boom its again mce error. so 1 core failed.

I was troubleshooting while encountererd that 2 of 4 sticks failed

I test each module to see which will post and 2 post of 4.

But the memory post dont work in dual channel May be the wrong cas though the freq is 1600mhz. As one is very old and one is 1 year old.

But is the failed core has anything to do with dual channel operation

Under what circumstances a memory wont post in dual channel.

Hello Nathan:

Based on the picture it says the expiration date is October 9, 2018, so, in that case, it will be under warranty. But, as you mentioned, I checked that information again on the same page and the processor is not showing, and also it is very strange that a second generation processor will have that expiration date, because they were released back in 2011, and the Intel warranty is for 3 years, so the expiration date should be around the year 2014, as you can confirm on the following link:

http://ark.intel.com/products/52213/Intel-Core-i7-2600-Processor-8M-Cache-up-to-3_80-GHz?q=Intel® Coreâ&# 132;¢ i7-2600 Processor (8M Cache, up to 3.80 GHz) http://ark.intel.com/products/52213/Intel-Core-i7-2600-Processor-8M-Cache-up-to-3_80-GHz?q=Intel® Core™ i7-2600 Processor (8M Cache, up to 3.80 GHz)

If you want to confirm and make sure if the processor is under warranty or not, then please get in contact directly with Intel, on the following link select "processor", and after that you will be able to choose chat, email, phone or online support, to contact them.
