what's the difference between https://www.amazon.com/Timetec-2133MHz-PC4-17000-Unbuffered-Computer/dp/B01NCYSLXH/ref=sr_1_3_sspa?s=pc&ie=UTF8&qid=1509814047&sr=1-3-spons&keywords=ram%2Bddr4&th=1 and https://www.amazon.com/Corsair-Vengeance-PC4-24000-Systems-CMU16GX4M2C3000C15R/dp/B01HKF450S/ref=sr_1_3?s=electronics&ie=UTF8&qid=1509813864&sr=1-3&keywords=ram%2Bddr4%2Bcorsair&th=1 in games performance.

The 8GB kit is 2133MHz while the 16GB kit is 3200MHz. It used to be that RAM speed didn't matter much, but today some games can see large benefits from RAM speed; sometimes as much or more than greater CPU speed.

And of course 16GB can allow some advantage in certain games over 8GB.

Thanks for the reply man,just 1 more think do the corsair ram will work in my motherboard ? this is my full pc spec https://support.hp.com/ro-en/document/c04907280

atefaskritouta21 :

According to HP's spec sheet for your motherboard it supports PC4-17000 (DDR4-2133). It does not mention faster RAM speeds, so it is not guaranteed to work with faster RAM.

That Corsair RAM is expensive already. I would suggest getting cheaper RAM that is still fast, even though there's a chance it might only run at 2133MHz. At least you won't have spent so much money.

This 3000MHz G.Skill is on sale, and is as cheap as 16GB of 2133MHz - https://www.newegg.com/Product/Product.aspx?Item=N82E16820232298&ignorebbr=1&nm_mc=AFC-C8Junction&cm_mmc=AFC-C8Junction-PCPartPicker,%20LLC-_-na-_-na-_-na&cm_sp=&AID=10446076&PID=3938566&SID=

But again, there is a chance it will not work at all because the motherboard doesn't say it works with faster than 2133MHz RAM. I say it might work because just because RAM says 3000 or 3200MHz, doesn't mean it has to run at that. It can be set to run at a lower speed.

^ I think this is correct and you're going to be limited to DDR4 2133 speeds. It has a Z170 chipset but it's an OEM Pegatron board and they probably didn't bother too much with memory compatibility.

Then i must stick with ddr4 ram at 2133mhz... Anyways thank you guys for the answer !
