Why is this GTX 1080 8GBS of GDDR5 and not GDDR5X?

[BF4FAN]

I ordered 2 of these GTX 1080s for my build:http://www.newegg.com/Product/Product.aspx?Item=9SIA6864CW5149&cm_re=gtx_1080-_-14-133-629-_-Product

And for some reason on the newegg's description it states that the card is 8GBs of GDDR5 and not GDDR5X. This doesn't make sense as NVIDIA advertised it as 8GBs of GDDR5X. I ordered 2 of these 4 days ago and they're coming tomorrow and I'm just so confused and am wondering if I just got ripped of or scammed or if this is just a typo or mistake on their website. Could it be possible I ordered 1080s without GDDR5X memory?

Gotta be a typo

It's a typo in the title. Under 'specs' it clarifies 8GB GDDR5X

It doesn't really important much. Having 1080 SLI is already the best you can offer
