[quote=iyours]Anyone experienced using both?[/quote]

Yes.

[quote=iyours]Which should i choose?[/quote]

The better one.

[quote=iyours]I don't really care about the pricing, i'm just wondering about which one performs better if there is a measurable margin.
If not I'll end up buying the cheaper one.

Kingston HyperX Fury Red 8GB Memory Module Kit - 2x 4GB, DDR3 1866MHz, CL10, DIMM - HX318C10FRK2/8
vs
Corsair - 8GB DDR3 1600MHz SDRAM Memory Module[/quote]

Now this is where it gets more complicated. Without knowing the CAS latency of the Corsair kit, no one can say for sure which one is "better." What also isn't known is if you are using integrated graphics. GPUs don't care about latency, but they do care about bandwidth which is where the HyperX kit has the complete advantage due to being dual-channel and its higher specified overclocked frequency.

thanks guys

I'm assuming you are building a computer. If that's the case I'll go for the Kingston since it is duo ram, single stick is bad. Secondly the Kingston clocks higher, at 1866mhz

Kingston, corsair are likely a rebrand of kingston anyway, maybe adata.

I'd take the HyperX kit, especially if cheaper than the Corsair stick.

Specs of each stick? They're both reputable brands, so go with whatever runs at a higher clock speed/lower CAS latency.
