Overall Review: It has been 6 years since I upgraded my PC and my previous CPU was an i5-2500k. Great CPU but always use the Intel diagnostics after a new build to make sure you have a good chip. I wish they would handle exchanges like they do in other online stores where they send you the replacement right away before you even ship the broken product back to them. The only downside besides the hassle of dealing with troubleshooting is having to wait 10 days to get my hands on a new chip from Newegg. The new chip is flawless and runs all tests good and have had no more blue screens. I then sent the CPU back to Newegg for a replacement and received the new one 10 days later.

I then downloaded the Intel CPU diagnostics tool and it showed constant errors while calculating prime numbers and the stress tests. The only other thing, which may be rare, is I got a bad CPU. I first tested RAM which passed the memtest86 tests and also tested with another motherboard with same results. Overall Review: When I built my new PC, I was having a ton of blue screens.

Pros: Great out of the box turbo featuresĬons: Always run diagnostics to make sure your new CPU is good
