PC parts gathering need expert openion

[Rawand Dabbagh]

Hey guys
I have decided to buy new pc parts i need your kind opinion about the parts if u can tell me please
i will go with the following parts :

motherboard Gigabyte Intel LGA 2011-3 X99 4way SLI/CrossFireX Gaming Wi-Fi Intel/Killer LAN ATX Motherboards GA-X99-GAMING G1 WIFI

cpu : core i7 5930k

ram : Kingston Technology HyperX Predator 16GB Kit 3000MHz DDR4 Non-ECC CL15 XMP DIMM Desktop Memory HX430C15PB2K4/16

grafix : evga gtx 980 sc acx 2.0 (3-way sli)

whats the difference with this non-ecc ram is it good or bad for gaming ?

regards

ECC ram is generally slower due to error correction and is typically used when additional level of reliability is required in servers or workstations... not really needed for home usage.

thanx for your reply raven

so what about going with this ram instead (Corsair Vengeance LPX 16GB (4 x 4GB) DDR4 DRAM 3000MHz (PC4-24000) C15 memory kit for DDR4 Systems (CMK16GX4M4B3000C15R) ) 360$

or this 16GB G.Skill Ripjaws 4 DDR4 3000MHz PC4-24000 CL15 Quad Channel kit (4x4GB) $493.89

ps: its gaming pc is it really necessary to get 3000 mhz speed or go with slower ram like 2800 ? or even slower

From what i remember passing DDR3 has hardly any impact on fps in games, its sometime even better to get lower frequency but lower latencies than other way around. I'm not a ram specialist, personally never cared about specific brands as far as i get decent ram with fairly low latency and good value I'm happy with that. I doubt it will make any benefit whatsoever paying even more for 3Ghz ram especially now when the prices are pretty crazy enough with DDR4.

aha i see , but i reviewed a comparison between all of the ddr4 rams in games they all seems the same performance wise
