ideal tech

Call Intel tech support line they will ask all the detail on your chip and cooler then tell problem, POP (Proof of purchase), address, contact and name. They will send courier come to pick up from you cost with costly price bare by intel and will send back a new one once they diagnose problem really cause of this processor if not all courier charge will be bare by you or you dont want you processor back. Test before you send

TS, what is the problem?

Did you try to test the mobo first?

TS said he already did troubleshoot all the hardware

i could help you RMA, charges RM50 only.
pm me if you haven't solved this problem~ XD

Call Intel's warranty hotline and provide them the serial number.
They will ask you to mail it to Penang along with the original heat sink and fan.
There are also some ticket/case number that you need to write on the package - just follow instructions from the service desk agent.

RMA process is very fast, will only take a week or so.
The new processor will be mailed back to you.

Paying for the courier fees is cheap and I recommend that you do it yourself.
