Hi, I've been browsing the forum for a post like this but had no luck.

Currently I'm using a KHX1333C9D3B1/4G (1 stick, kingston)

I want to buy a Fury HyperX HX316C10FK2/8 (2 sticks, kingston)

I was wondering if I could run the 2 Fury sticks in dual channel and at the same time, the regular HyperX BLU "alone".

I found some PDF's online, just google the models above and they will come up. A lot of technical information regarding latency, voltage, etc., is there.

Thanks in advance. My motherboard is an ASRock extreme4 (z77) and I have a intel i5 3570K + GTX 650 ti.

Potentially but here is how I see it. You should order your 8GB kit regardless because if you buy it and it works then you have 12GB of 1333MHz ram running in single channel and you sacrifice just a little bit of performance for a larger amount of RAM. If it doesn't work then you just run your 8GB of RAM in dual channel at 1600MHz. In reality the 8GB is all you need so it's a win win for you either way.

Having different latency and speed do you think it will run without problems?

If you add the third RAM stick, you won't be running in dual channel, and there's a chance your system could encounter instability. Give it a shot. Dual channel really only gives about a 5% performance increase anyway, and if you run into problems, just remove your third.

Latency and speed don't matter. They'll just default to the lowest common setting.

I read SR-71 Blackbird's article, IamTimTech and Brillis Wuse' post and they both say the same, thanks guys. I'll just give the old 4 gig stick (no pun intended) to my girlfriend or sell it.

Sweet, good for you buddy. If you have resolved to remove the stick you have now, then may I recommend the G. Skill Sniper Series 8GB kit. The ram is on sale today for $62 on Newegg. Excellent Ram with a Cas Latency of 9.

The kingston has a cas latency of 10 and is slightly more expensive than the G. Skill Kit. (today, prices constantly change). The lower your cas latency the better your ram performs. And G. Skill and Kingston are hand in hand for reliability.

I was thinking of getting Corsair's Vengeance, what do you think?

You will have to point out which Corsair kit you are looking at, but Corsair tends to be more expensive for a kit with the same specs as other brands. There is no reason to pay more for a kit with the same specs because they will perform the same. Even though memory failure is uncommon in general; Corsair and Crucial have slightly higher RMA rates than G. Skill and Kingston.

If you want to spend a little more on your RAM then put your money in the right place, you want to find the sweet spot of performance to dollar. In my opinion this is a 8GB 1866Mhz Cas 9 dual channel kit. If you increase your speed anymore your cas and price start to raise with no performance gains so to me that is the sweet spot.

Here is a comparison of 8GB kits running at 1866Mhz with a cas of 8 or 9. As you can see the Corsair is at least $11 more than all the other options.
