Issues Enabling XMP

I just installed a couple of new memory sticks and am attempting to enable the built in XMP profile. I tried to do so through the Intel Extreme Tuning Utility, but when my computer restarts, the program keeps saying that it "exited unexpectedly" and the new memory timings revert back to default. Is this indicative of system instability at the new timings or is this simply an issue with the utility itself? I would manually go and try to change them through the BIOS, but I can't figure out what key enters it at the moment.

Thanks.

Motherboard: Mythlogic Pollux 1613, Intel Haswell Rev.06 Chipset, Intel HM87 Rev. C1 Southbridge
CPU: Intel Core i7 4800MQ
DRAM: Crucial Ballistix Sport 1866MHz CL10 1.35V (2x4GB)

You have a mobile platform with an H series chipset. Last I checked it the chipset doesn't allow you to overclock to specs above 1600MHz which means your kit is running at 1600 now.

Now I;d be able to confirm it if you could state your laptop model...? Your first post was pretty bland though.

It is a Mythlogic Pollux 1613-A Black, which is a Clevo P151SM variant.
My DRAM frequency is reporting as 931.2 MHz, so I am pretty sure the memory is running properly at 1866 MHz.

Yeah that is right. Has the issue been resolved? I thought OP wasn't able to get the kit stable at 1866MHz or around that number.

On an H67 build with Intel XTU support I couldn't get it to boot into 1600MHz via the software and always got an error similar to OP. The reason behind that was because the processors memory controller didn't support 1600MHz.

On H67 could try raising the the MC (memory controller) voltage prior to enabling XMP and then also raise DRAM voltage (depending on CPU it might carry 1600) the System agent voltage (VCCSA) can helps there also, plus you can prob click the BLCK up 1-2 and get a small OC on the CPU and rest of the rig

The i3-2100 is an HTPC for my pal. The i7-4700K build is for my in law...its yet in the air awaiting arrival. Dunno how long it'll be until I receive it.

I'll contact you via PM or on the thread I created if there are more developments ;)

Yeah, the problem isn't the memory clock speed. The XMP profile just slightly modifies some of the timings. That is why I thought it possible that it may just be an Intel utility issue rather than actual instability in the system, but I wanted to make sure before I went into the BIOS and tried to change them manually.

Usually tighter timings are better off input manually on some systems with a slight bump in voltage. Have you managed to enter your BIOS? It can be tapping DEL, F2 or a combination thereof soon after powering up your laptop.

Are you sure it isn't covered in the manual that came with your system?

I have tried all the normal combinations, but have yet to be successful in interrupting Windows startup. Unfortunately, the included documentation is rather sparse. I will likely contact the mfg on Monday to get a definitive answer.

I will update the situation once I have tried the alterations through the BIOS.

So, I finally figured out how to get into the BIOS (Stupid Windows 8...) and I tried setting the memory timings manually, but for some reason, they continue to revert back to default once the computer restarts.

Any suggestions?

I just double-checked - as oddly worded as it is, the only option to save changes in the BIOS is "Save Changes and Reset." "Reset" is analogous to "Restart" here.
