DDR3 1600 is all that works out of the box.

The BIOS has no screens to change memory timings or multipliers, and the BIOS does not allow overvolting the memory which is needed for XMP settings.

You can use Intel XTU to increase the multiplier, and I was able to get the OEM memory to run at 1866Mhz.

I'll see if I can dig up screen shots of the timings.

Hey Dan - thanks much.  Any screen shots you can find would be much appreciated.

I can't find the screenshots. I gave this system  to a family member and I don't think I kept all the screen shots, but here is post I made on another forum along with some test results and my final timings.

I think the dell forum will block the link, so replace the word DOT with a period and paste this into your browser.

forums DOT hardware-revolution DOT com/showthread.php?tid=5321

I ended up staying at 1600 Mhz but tightening up the latency to 7-9-8-18.

Dell factory timings are  DDR3-1600 11-11-11-28

keep in mind, not all RAM is created equal so you may do better or worse depending on your memory.

good luck

RE: Dell XPS 8700 RAM

One more thing. I didn't put in the notes but I was eventually successful getting 1866 Mhz, but the latency was really sloppy and the performance was not better.  Everything I've read indicates faster memory frequency  ( speed )needs a little more voltage, and that isn't an option on the 8700 Mobo.

And to compare some results on my non-dell system I'm able to take DDR3-1600 Mhz memory to 2400 Mhz andthe memory voltage needs to be increased from 1.5V to 1.63 volts.  The latency goes up too and overall the system performance is slightly better according to benchmarks.  However, in actual use the performance difference is barely noticeable. This is an i7 4790K running at 4.7Ghz with a Z97 chipset.

So my point is, you might be able to boost the memory speed a little, but in the end I think you'll find the net result is minimal.

But, give it a try you might find it works better for your needs.
