I only have 1 close comparison: i5-3570K OC'd to 4.2 is doing about 8/Day/Core of LL; or about 48 per core in 6 days.
It's doing two 56.5M LL per core per month; each worth about 120 GhzDays.
Not offense but I would think the 4690K should do quite a bit better than the 3570K.
Not sure what RAM I'm using off hand; certainly not 2800...might be 2400

[simon389]

Changed the RAM setting from DDR2400 to DDR 2666 and it is still stable. Thanks for that note! The machine is cruising now. Hope the few doublechecks I have lined up don't email me with any errors and we'll be good to go. Thank you everybody for your help.

Just a four month update... everything is finished and the machine is FAST - cool - silent. I've had a bucket list "life goal" to have a fast Intel computer in the corner of my house crunching Mersenne's and now I have one. Thanks everybody.

How about reliability? Did all DCs checked in successfully?
And just out of curiosity, have you taken any power consumption measurements?

The setup is great! Reliable for sure. Not sure about power consumption. The initial few DC failed, but all after that DCs were successful. I have it set to 10% DCs, so hopefully that is enough to let me know if things should change.

Those 190GhzDay LLs are taking me about 27 days each, give or take.

Below you can see my results.

For the two red results you don't know yet that the result is bad. It may be the original LL being wrong. [edit: It happens to me all sometime, and when I triple-check, my residue is right.]

Probably true, especially since the other runs verified okay.

Tell ya what, I'll pick up those 2 mismatches and have an answer for you by tomorrow. (CORRECTION: In 15 and 17 hours respectively)

So cool! Thanks!

Is 27 days for a 190GhzDay LL exceptionally fast, or is it just par for the i5-4690K course?

It'll depend on the exact FFT size it ran at... you might want to run the benchmark in Prime95 and compare with others who have the same i5-4690K:
Benchmarks for i5-4690K (I limited that to just benchmarks since Jan 1 of this year).

You can look at the 4MB FFT size timings for an idea of what you could expect on your own system. Those times are in milliseconds per iteration. So the total time (like 27 days) would depend on the exact exponent you were dealing with... it's better to measure the per iteration times instead.

It isn't. 190GHz Day / 27 days = 7 GHday/day. According to http://www.mersenne.ca/throughput.ph...6144&mhz1=3500, your CPU should be getting about 13-14 GHDay/day. So this is about half of that. Something's off.

Memory in the wrong slots, so running single-channel instead of dual-channel?
