First-time builder, Will OCZ RAM w/ large heatsink fit?

NewEgg customer comments say that RAM fits on that motherboard.

Why such honking great big heatsinks? Just go with the standard OCZ version with normal heatspreaders, but get the 1600 instead of 1333. Then you have less headroom to make it to that higher clock. Plus the difference in price shouldn't be that great.

If you are really set on using them then my advice would be to go on gigabyte's website and see if they have a schematic type drawing of the board with measurements. you'd be suprised, I have found this sorta stuff on a number of different hardware manufacturer's sites before.

I just don't know much about RAM and how hot it gets under stress. Are normal heat spreaders usually sufficient. I plan on gaming, so I thought "bigger is better", but perhaps I'm going for overkill.

My build is almost identical to yours (same motherboard, cpu, 4870 for me)

I used a Xigmatek S-1283 cpu cooler with this ram:

The cooler covers 2 of the ram slots close to the cpu so I had to use the far ones on the motherboard. So depending on what type of cooling you get, you might not be able to use all the ram slots.

Didn't even think of a cpu cooler getting in the way, did your cooler just not fit with the large heatsinks on the ram, or the sticks themselves?

It hangs over the ram slots so there's not enough room to put in the ram. I don't mind I guess cause I don't really need more than 4gb of ram...

Ok, in all seriousmess, with your system specs, four gig of 1600 RAM will be fine. I wouldn't fuss too much about having more (you can check out on OCZ's webpage a comparison of how more RAM affects gaming performance, and anything over 4gb is minimal). As for the 'overkill' heatspreaders, there is a reason why 'normal' heatspreaders are the norm... it's because thats all the average user will need. I gave the advice of getting 1600 with normal heatspreaders instead of 1333 with big heatsinks because I assumed you wanted to overclock to 1600. If that isn't an issue, then I guess you could even go with normal 1333 modules, but personally I think the small price difference warrants stepping up to 1600.
Give these a go:
