Although Intel does not officially supports overclocking, since overclocking is under customer’s risk, you can test the processor on another motherboard that has a BIOS capable of supporting overclocking features, to see if that solve the issue.
Also since you purchased the processor at ebay.com make sure that it is not a counterfeit processor, you can do so by calling Intel Customer Support center and providing all the information on top of the processor as showing here:
They will be able to tell you if that is an official processor, or an engineering sample.
Thanks for this. The problem is, the IHS has been sanded to the copper layer, so that the nickel plating (and what was written on it) disappeared. I found it strange at start, but when I saw "875K" in the bios, i was eased. When I saw that the multiplier was locked, though, I started worrying. The only number I can still see on my CPU is the ATPO. I will look around if there's a way to make it authentified by Intel.
Okay. According to the Intel Processor Identification Utility I just downloaded, the chip is indeed a pre-release one, not intended for sale and resale. This is just a 870, not a 875K. I contacted the seller through Paypal's litigation system.
