Motherboard: http://www.newegg.com/Product/Product.aspx?Item=N82E16813157229

Old memory: http://www.newegg.com/Product/Product.aspx?Item=N82E16820231315

Upgraded to 2 sets of http://www.newegg.com/Product/Product.aspx?Item=N82E16820231558

I was hoping that it would be a simple bump from 16 to 32, but I'm not even getting a boot screen. The new memory is seated correctly, and the old memory still works. The m-board *should* support 32g, and I think I've read the specs correctly, but I'm not getting anything w/ the new memory. Is the latency difference the problem?

Any advice appreciated.

I fully imagine both sets are fine - by themselves as they were intended to run, any time you mix sets it can be problematic, sticks in a single set are tested to all work together, which is why a 4 stick cost a little more than two 2 stick sets....also the XMP programming is for the packaged set only so you have 4 sticks which will take different advanced timings than does a 2 sticks set....see this every day!

Anyway, can you post your advanced timings for the DRAM....or you can first try setting the sticks up manually, freq to 1600, base timings to 10-10-10-28, DRAM voltage to 1.57, CR (command rate) to 2T, and raise the VCCIO voltage + 0.12 higher than it's currently at - and back to the advanced timings with your rig, all I'll prob...

Thank you for taking the time to comment. Serves me right for trying to save $50. I'll get the set of 4 instead of 2 sets of two.

re: posting the advanced timings - I can do that by figuring out which were paired (they've gotten shuffled around), putting those in, and working off the bios readings? I don't know that I'm going to do this right now, but I want to understand you comments.

Much appreciated. I'm glad you guys are around to answer a newbie question.
