You're fine, with your CPU, the sky's the limit, the 4790K should be able to run 3200 DRAM, the 1866 should prob run fine with the CPU at stock, simply enable XMP and select profile 1
Many thanks all! I am relieved...
Although I don't know what is "cpu at stock", "xmp", "profile 1"????
If anyone is kind enough to elaborate, otherwise I will need to do my homework, I guess...
My supplier just received the new 4790K in stock and is shipping it to me. Can't wait to play and have my teens to play with this ultra_expensive_toy!!!! Hopefully it will keep them busy...

CPU at stock simply means you haven't OCed it, XMP is a setting in BIOS, it reads info from the DRAM (different profiles programmed in the DRAM for different settings, and Profile 1 is the base setting for the DRAM to run at advertised freq
In English:
CPU at stock means that it runs at the same speeds as you bought the CPU, no overclocking - no raising the speeds of the CPU. For example, if the CPU box lists the CPU to have 3.4 GHz, when you overclock it, you can raise it to 3.5+ GHz, which is kind of bad for the CPU, but good for you, as it gives you advantages of higher speeds, and so smoother gameplay/video editing/modeling/else.
eXtreme Memory Profile: XMP Header, XMP Profile 1 (enthusiast settings - for casual use), XMP Profile 2 (extreme settings - for overclocking purposes)
Really, the only reason I'd buy such CPU is for overclocking. 4 GHz is a beast, but 4.5 is a monster! Anyways, the newer CPUs are being released every how many, 2 years? So, in 5-6 years we might have an octa-core CPU clocked at 4 GHz. And in modern games, even though the CPU plays a pretty big role, the biggest and most important role goes to the graphics card, not CPU. Keep that in mind.
And to say the word why I read this thread... I had the very same question about memory... After all, I guess we shouldn't forget that it's DDR3 - Double Data RAM (Random Access Memory) version 3, and if it says it supports 1600 MHz, it means it supports memory speeds up to 3200 MHz... Right..?

Nope! Advertised 1600 spec DRAM is at DOUBLE data rate, true freq for advertised 1600 sticks is 800, which is the stock DRAM freq for Haswell....3200 sticks require a 4790K (maybe a 4770K with a good OCer setting them up)
