To Dell's credit, they are going to RMA the computer and refund, even though it was sold by a third party, antonline.com through newegg. Excellent customer service from Dell, though.
It looks to me like the current limit throttling from the motherboard was designed by Dell to not run the CPU too hard to prevent wear/failure and prevent Dell service calls.
Yep, typical Dell. Sell you something with high specs then run it under spec to prevent other flaws from showing. No matter how good Dell support is they will never make up for the inferior products Dell sells.
I'm having fun!!! I'm just not sure if it's net fun or gross fun.
Tim, did you get the replacement? How is it doing?

The replacement was exactly the same. They were both designed to not allow the cpu to run full-on for any amount of time. Other than that, nice computers. Did not fit my needs at all for crunching.
So I'm building a i5-4690k as was suggested. The first mobo was doa, waiting for replacement. I'm going to run linux on it. Time to brush up on my command line. And see if I can get it to work over my windows network here at home. I want to log in from my windows box and see the log file to look at progress. I have done it before, but that was years ago. Should be fun.
Folks, I've built a few Intel core i5 4690s and I've noticed something odd:
days between finishing P-1 test and then finishing the PRP test and reporting "x is not prime" and then getting a new test:
Intel core 2 duo, 26 days
Athlon II x4 645 3.1 ghz, 18 days
Intel core i5 4690 3.5 ghz, 16 days
Intel core i5 2500 3.3 ghz, 9 days
Why is the i5 2500 faster than the i5 4690?
Whether linux or windoze, about the same speed. There's 3 or 4 boxes of each type cpu, the number of days is an average for that cpu. I've not done anything to tweak the prime95/mprime client. All cpus report 100% use, one client working per core. None are overclocked. Prime95 reports using FMA3 instruction set on i5 4690 while the i5 2500 reports using AVX. The 4690 was way more expensive to build, I would have thought they would be my fastest boxes. What is wrong here? What do I have set up wrong? The Dell I returned (4690) ended up being the same speed as my hand built 4690, so I don't think it was Dell. The problem must be between the keyboard and the chair. But I don't know what.
