Flex Mode with a Haswell OC

having decided against going with a Skylake build, i picked up a 4690k and have an Asus Z97 Pro Gamer board on the way. the guy that sold me the 4690k threw in 16GB of Crucial Ballistix (8GB x 2) 1600 DDR3 with 9-9-9-24 at 1.5v. at the same time i have a perfectly good 12GB Triple Channel kit from my X58 - Mushkin Redline (4GB x 3) 1866 DDR3 with 9-9-9-27 at 1.5v. it appears that a decent 4690k OC will cut into the memory frequency, but i'm hoping to achieve 4.5GHz and at least 1866Mhz with the same timings.

 

so... i realize running only two of the Mushkin sticks for 8GB total will most likely not be enough down the line. 12GB should be plenty for my needs(gaming), but the third stick will trigger that flex mode. it's nearly impossible to find a single 4GB module with the same part number to fill the 4th slot(very possible, actually, for $119 for 4GB at RamExperts, geez), but that is the plan eventually. the other option is to keep the Crucial modules and try to squeeze 1866MHz out of them, which seems like a stretch with 8GB per module density, after reading a few Haswell OC guides. 

 

so which one should i sell? i don't necessarily need explanations of why this and why that, depending on this and that. just your personal preference. what would you do? the game i have in mind is The Division, and the 8GB of Mushkin that would still run in Dual Channel should be enough for the busiest moments in the Dark Zone, but i still want to have that extra 4GB to fall back on, in case i need to stream a movie to Chromecast for my kids while playing the game. last time i used it with Videostream to stream a 1080p bluray Chrome was using right around 3.5GB of RAM to do it.

Bit late, but I would keep the 12. Are you really doing something that will see an improvement from timings? Or, alternatively, could you use two of each for dual channel and just OC it as far as it will go?

Tip to those that are new on LTT forum- quote a post so that the person you are quoting gets a notification, otherwise they'll have no idea that you did. You can also use a tag such as @Ryoutarou97 (replace my username with anyone's. You should get a dropdown after you type the "@")to send a notification, but quoting is preferable.

 

Feel free to PM me about absolutely anything be it tech, math, literature, etc. I'll try my best to help. I'm currently looking for a cheap used build for around $25 to set up as a home server if anyone is selling.

 

If you are a native speaker please use proper English if you can. Punctuation, capitalization, and spelling are as important to making your message readable as proper night theme formatting is.

 

My build is fully operational, but won't be posted until after I get a GPU in it and the case arted up.

That is what I really want is to keep the Mushkin kit. With a little more searching I found the exact same fourth module for $54.99. Not bad I guess. I definitely want some coin back, so the crucial kit is going on ebay. Thanks, decision made, I think.
