For the rock solid stable 2x8Gb in 2400c10 mode - what route should I go?1) Factory rated 2400c10
or
2) Labeled as 2666c11 and downclocked to 2400c10.
The highest speed bin produced is DDR3-2133 and even those are fairly new chips. What chips the DIMM manufacturer uses varies, you'd have to remove the heatsink and look at the markings on the chips

I guess there are no other options besides Hynix MFR for the 2666+ rated modules.
So I am talking about the same ICs sold in the form of 2400c10 and 2666c11 sticks.

Could you please name some products with these chips on board?

Take a look through the products provided by Micron, Hynix, and Samsung. None of them exceed a 1066Mhz clock rate at the highest speed bin available. DIMM manufacturers test these and overclock them appropriately to reach speeds beyond DDR3-2133 just like they did to reach DDR3-2133 before DDR3-2133 chips were available on the market.

Since the DDR3-1600 is no problem for 2133 rated module, why this is not the case for 2666/2800/3000 to 2400 step down?The DRAM speed bins are backwards compatible due to the internal design of the chip. A chip with a DDR3-2133L speed bin is guaranteed to be backwards compatible with DDR3-2133M, various DDR3-1866 speed bins, various DDR3-1600 speed bins, various DDR3-1333 speed bins, various DDR3-1066 speed bins, and various DDR3-800 speed bins. The calculations for converting read-command-to-data-ready to bus clock cycles can get a bit complicated so I won't go into the details.
In theory, a chip that is overclocked to DDR3-3000 should also work at DDR3-2800, DDR3-2666, DDR3-2400, etc... but there's no guarantees because the chip wasn't designed with those data rates in mind and no testing at the factory is done to validate it.

Thay have tested the 2666/11 to run at that, so it will run at 2400/10 without problems. It's prob the same ICs binned by the manufacturer for the higher tolerance....The GSkill Tridents 2666/11 gen will run at 2800/12 with no problem and backward to 2400/10, 2133/9, 1866/8 etc....the 2400/10 gen have OC room to 2666/11 or 12...have tested with a number of their sets

Didn't get any response from moderator Tradesman @ gskill.us forum, and my account wasn't activated there, thus I decided to go with Transcend I am more familiar with.
I bought these Micron D9QBJ based DIMMs
http://www.amazon.com/gp/product/B00AQT2LXO/
2133 rated by Transcend and overclocked to 2500 here
http://uk.hardware.info/reviews/5246/13/13-16gb-ddr3-me...
I hope to get stable 2400 from it. We'll see.
BTW they got fantastic overclocking results for G.Skill 1600c9.
These Team Group DIMMs was very tempting
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Great price and unfortunately US only webshop.
