Question 1

Why does it say DDR3 2400 in the ram memory technology area and if that isn't a mistake, what does that mean vs "DDR 400"?

Accepted Answer

Its  not a typo. RAM can only run at 2400 speed unless your cpu is capable of handling overclocked RAM. Which 3200 speed RAM is indeed, factory-overclocked. When you install the RAM, you need to enable the XMP RAM feature in the bios in order to run at 3200. Otherwise, it will run at 2400 like normal RAM. So before purchasing this, you need to make sure that your motherboard will support 3200 RAM (which means that you will have the option to enable XMP in the bios) and of course, that your CPU can too.

Question 2

Anyone using with a ryzen 5 1600?  what speeds can you get with this?  putting together a gaming pc with my son - have an asus rog b350 mobo.

Accepted Answer

I have the same motherboard. asus ROG strix motherboard b350-f right?
I recently had downloaded the most recent bios to be released for the motherboard and when my ddr4 3600mhz cl18 2x16gb (32gb total) showed up only 18 hours after I clicked place order btw, i turned off pc, cleared CMOS, took out my old ram after unplugging the pc's power unit and waiting 30 seconds, then put in the new sticks.  Only two dims, dual channel (cause that is the best) and it worked out of the box, just setting the docp profile to be selected..
BUT
I use a 3800XT on my b350-f mobo, and again it has the MOST RECENT BIOS FLASH.  So i am not sure that FIRST GEN Ryzen is going to cut it.  on my 1700, on this same motherboard i could NEVER get above 3000mhz and that was with a lot of custom fiddling 
so yes it works with at least the 3800xt ryzen chip, which is the same socket as the first gen of ryzen, so just update via secondhand or FB marketplace and buy a 3800xt
(why the XT variant?   Good Question, well that 3800XT is the only variant of desktop cpu's that have the name sake of the 3000 series chips, but actually has an architecture MUCH closer to the 5000. 
Mine boost as high as 4.95ghz. first time ive seen a ryzen cpu report a core hitting that close to 5ghz 
the 3000 series chips will not boost that high... no matter what

Question 3

Can you mix c18 and c16 of the same corsair ram ? can you make them identical in bios?

Accepted Answer

You can mix speeds, but it's not recommended.  As another said the system will try to run your memory at the speed of the slowest RAM.

Yes you can change BIOS setting to make both RAM kits set to the same timings, and that usually means setting the tertiary timings as well, to make them the same, so they are matched identically.  Of course both kits have to accept those timings.  This is probably the best method when mixing kits.  So, set the slowest kit first to where it's stable, and that means also running memory tests, then add the second kit and match the timings.  And yes this means you're making them identical in BIOS.  The CPU and MB also play a factor in all this, and to me it sounds like you're making this a system with 4 sticks.  If you're getting the CPU at the border of its capability with 3600 memory (too much for Zen, Zen+, borderline for Zen2, Zen 3) you'll probably have to boost the memory controller voltage a tiny bit, and watch some video, look at what's suggested when trying to run 4 sticks at such a high speed.

Question 4

Can I overclock these to 3200mhz on a asus b350 plus/ ryzen 1700? I have tried and all I get is the stock 2133mhz running dual channel.

Accepted Answer

I was able to overclock these up to 3200 MHz and run windows and games BUT it’s not very stable, many errors, but I was able to overclock stably at 2933mhz at 1.39v , was afraid to turn the voltage any higher and burn them out.
