GA-Z77X-UD3H + i5-3570K = which Trident X?

I can help you narrow it down to what Intel will accept under their CPU warranty which limits ram to 1.5v although the second doesn't look to be a realistic option
F3-1600C7D-16GTX
F3-1600C7Q-32GTX
Hope it helps

I noticed you recommened lower timings and cas latency with lower bandwidth as opposed to the others with higher bandwidth and higher timings and cas latency.

Would you mind explaining why?

Those are the only two kits that are at 1.5v, no other reason. If you're not concerned with the CPU warranty issues, I could propose faster...

I'm not so concerned about that, unless this is a super common issue. As long as it's under $100. I have been looking at the trident X models that say, "For Z77 & 3rd Generation Intel Core Processors". I really like the idea they will be optimized for my specific setup.  

Honestly, its unlikely Intel would be able to tell why the CPU failed anyway (if they even check) but it isn't a common occurance to my knowledge. I did feel somewhat obliged to keep it safe.
Here's what I would choose then F3-2400C10D-8GTX mostly because I'm somewhat cheap but I think there's enough of a balance in the speed/price tradeoff. There is the loss of latency at that price point compared to the others but unless you're looking to benchmark, I don't think it'll affect everyday performance noticably

So, this is going to be faster: http://www.newegg.com/Product/Product.aspx?Item=N82E168...

While this is going to be slower: http://www.newegg.com/Product/Product.aspx?Item=N82E168...

The first has lower timings and lower bandwidth while the 2nd has higher bandwidth and higher timings.

I'm confused.   Ideally what makes fast RAM is lower timings and higher bandwidth right?

I'm sorry for asking so many question. I am just really confused and I want to understand the difference and what makes one faster than the other, also why they would tag one with, , "For Z77 & 3rd Generation Intel Core Processors ", and it's still slower than the other?

Edit, If it's going to be noticeable at all really, I think I'd rather go with the faster option.

Ideally, yes, higher bandwidth, lower latency is the goal but there are tradeoffs and as bandwidth increases, latencies also increase. DDR2 with latencies of 4 and 5 were common but the bandwidth wasn't there. In the world of ram speed, bandwidth/frequency is more important than latency - there's a mathematical formula that explains the interaction but I don't have it bookmarked anywhere...

Ahh okay! That's what I was thinking. So ideally if I am happy with the bandwidth/frequency then it's okay if the timings are CL10, 10-12-12-31 because I would not need to OC.

I just realized that all of the options that are tagged with, "For Z77 & 3rd Generation Intel Core Processors" have high CL/timings and have no lower than 2400 bandwidth/frequency. Is this for the reason I mentioned above? They are fast and do not need to be OC'd?

Edit, Looks like the GA-Z77X-UD3H max memory module support is 2800MHz. Think I should get something that will OC to that or will I be fine? The most resource consuming activity I do is game on 1920 x 1080.

You will still need to overclock the ram to get those speeds but you should be able to use the XMP (extreme memory profile) setting to get the best speeds and timings from the ram - a one step operation, in BIOS click XMP enable - if overclocking your CPU, do your CPU clocks first before enabling XMP

That one I can't really say, the whole optimized thing confuses me since, as I pointed out, Intel says 1.5v max

The general concensus is that above 1600MHz, benefits will only be noticed by benchmarking programs with no (maybe minimal)observable differences in performance - I haven't personally checked but I am inclined to believe that. I personally can't justify the cost of 2800MHz ram - $300 for 8GB of ram is quite the investment IMO.

This is all you need:

A greater frequency is not necessary, it is only for extreme overclockers looking for maximum results. It also explains the cost of RAM. Only extreme overclockers can justify DDR3-2800 RAM because they can use such high performance. For normal users, sufficient capacity is more important than sufficient speed. So while $300 for 8GB may seem ridiculous to one, it is normal to another. Lower capacity is also better for overclocking, so that is another difference between the two types of buyers.

It is without a doubt that higher frequency RAM will perform much better than lower frequency RAM. Whether one can utilize that performance depends on the user. For example, if you are gaming, word processing, surfing the web, you'll never know what DDR3-2400+ can do or the "observable differences". If you video edit, 3D render, photoshop, or deal with large files, then you will notice a significant "observable difference". Something that normally takes 15 minutes can take 5 minutes instead. So in the end, it just depends on the user. But in any case, high performance RAM is worth the money, and whether you think you can see it with your eyes or not, the computer is still processing much quicker.

Intel states 1.50V because they do not support overclocking. Intel supports DDR3-1600 CL11 max (standard); this is what the CPUs are designed for, which is why CPU overclocking is necessary to enhance DRAM overclock.

Thank you
GSKILL SUPPORT

Great explanation! Thank you so much.

A couple questions:
You said, "For normal users, sufficient capacity is more important than sufficient speed." By capacity do you mean the literal capacity like 2GB/4GB/8GB stick? By speed do you mean frequency such as 2400MHz or the timings/CL?

Also, is the fan that is included really that necessary?

I do transfer movies like once or twice a day that are above 4GB but other than that there's not much else I do that requires much resources other than gaming, which is what this build is for. Sometimes I trans-code movies, but rare. I do overclock, but not on any crazy water-cooled level, just minor OC's.

Thanks again!

Thanks so much! This is amazing support. Seriously. Keep up the good work guys.

I still haven't chosen my ram, I recently got into video editing and plan to continue with it, as well as hardcore gaming. So I'm dealing with extremely large raw recorded footage of in game play and pretty much constantly rendering/encoding. The file sizes are as big as 72GB raw sometimes.

I'm also transcoding movies/documentaries in high quality that can be larger than 16GB.

Would this change the ram that was recommended earlier?

It doesn't have to be specific, it can be any G.Skill ram model.

Really appreciate it. Looking to make an order asap.

I have a strange feeling this might not get a response since I marked it as "solved" a while back.  

You might PM GSkill Support - I don't think have much more input of value for you. Especially looking at the costs of the kits - I can only say, wow.

Yeah I did, I'm sure I'll get a response once they have time.
