Hello everyone! So while using the mentioned website I get this message:
"The Corsair Dominator Platinum 16GB (2 x 8GB) DDR3-2400 Memory operating voltage of 1.65V exceeds the Intel Haswell Refresh CPU recommended maximum of 1.5V+5% (1.575V). This memory module may run at a reduced clock rate to meet the 1.5V voltage recommendation, or may require running at a voltage greater than the Intel recommended maximum."

I currently have 16gb 1333ghz RAM and I plan to upgrade to the mentioned 16gb 2400ghz RAM.
can someone explain this flag and tell me if I can ignore it or if it would be a waste of money?
 
Solution
There's nothing to do. Just go to the store where it shows the best price on the modules you want and buy it. PCPartpicker also has the "ignore compatibility" option because they know their default cross reference isn't always accurate. I guess I'm not sure what the problem is you're having. It's just a notation on the site for noob builders so they don't royally screw up using components together that are entirely incompatible.

I personally would recommend only going with the 2133mhz so you don't overstress the memory controller. The 2400mhz will probably, almost certainly run, but everything you do that increases or uses higher voltage tends to shorten the lifespan of components to some degree. This is why modern hardware is going...
Dominator RAM is overrated. I would stick with some 2133 G Skill the difference between 1600 and 2133 is even less than 3 FPS. Often times it makes no difference at all. Also a 4x4 is going to perform faster. If you have H97 or any other chipset except Z97 or Z87 you can use a max of 1600 speed.

I would go with this however:

This is a good non oc mobo RAM. (Low latency 1600 speed)

1.65v will work on Z97 or Z87.
 
What is the CPU and motherboard model numbers? If it is an unlocked Haswell Refresh CPU, it will work fine so long as the board is not an H97, B85 or H81 motherboard. If it is a locked chip, then stick with 1866mhz 1.5v modules. For H97, B85 and H81 boards, 1600mhz is the supported maximum speed. Z87 and Z97 support the 1.65v modules on unlocked chips.

I wouldn't recommend going over 2133mhz as the modules get more expensive after 2133mhz and don't offer much if anything beyond what the 2133mhz modules provide for your investment. If you're gaming, they probably won't do much more for you than 1600mhz modules unless you're gaming at very high frame rates but since the prices are comparable these days between 1600mhz kits and 2133mhz kits, it's senseless to not go with the faster modules if they are supported.
 
You will be fine with 2133mhz RAM with the 4790k and the Hero VII. You will "probably" be fine with 2400mhz but it will likely require a bit of minor overclocking as well. In this case with that board and cpu, I would entirely ignore the PCPartpicker flag as it's based on the default Intel spec for native memory support, not XMP or manual settings.
 
I have serious concerns about some of your component choices though. I would for certain not be going with that case in any event, would choose different case fans that actually come somewhere close to their rated specifications and would not concern myself with the RAM being a Platinum version when standard Vengeance or Ripjaws modules will offer the same performance. I CERTAINLY wouldn't ever go with that RM series power supply that could not even pass HardOCP's testing much less score high or offer long term reliability. It's horrid and you can do MUCH better for a similar price, like this unit which is built for EVGA by Super Flower:

After rebates that unit is currently about 95 bucks and is one of the best units currently on the market under 120 dollars.

As for the case, I highly recommend considering a different choice. The NZXT Phantom 410, Phanteks Enthoo Pro, NZXT H440 and Fractal design define R5 are all much better cases in my opinion but the C70 is ok too.

You shouldn't need that add in fan controller and I'd avoid using one if possible. The Hero VII has 2 CPU fan headers and 4 chassis fan headers, which can be expanded to 8 case fans using these if necessary:

And makes for a much simpler and better automatically controlled fan environment using the bios settings for the fan profiles. It also reduces clutter inside the case and the need for using an additional drive bay and knocks 30 bucks off your budget.

I'm not sure what the purpose of all the different SSD models is, but I'd recommend sticking with one brand. In reality, the Samsung 850 EVO and PRO models are, last I checked, the fastest consumer SSD's on the market judging by reviews and AS SSD benchmarks and are less expensive than some of those slower models. I have the 850 EVO and have installed them in many builds with great success and no issues, unlike the 840 EVO model with all it's troubles.

Lastly, I'd avoid the H100i and it's quirky Corsair link setup. I've seen a very high number of users who have either had issues with the link hardware or software or just plain had less than acceptable performance with the units. If you must have an AIO cooling solution, I'd highly recommend the Cooler Master Nepton 240 or 280 or one of the Swiftech coolers.

In case I've missled a few, I already have my PC, the only thing that isn't the same is the RAM I am unsure of which Corsair RAM I would go with, Pro, vengeance or Dominator. But I will indeed be going with corsair, their products have never let me down, and I have a very Corsair heavy build. The only thing I'd say could be better are their headsets, but I am enjoying my h1500. the power supply I've not seen any problems with, but certainly EVGA I hear good things from as well.

I have a fan controller, and I don't use my drive bays for anything honestly. The controller was from my last pc which needed. And I'm not sure if the fans listed on PCPartPicker are the right ones I got, because of how weird they label them compared to Newegg, and compared to Corsair. And I do have a fan controller which puts them at 100% if I play games I know will need better cooling, Witcher 3 or Guild Wars 2 for example.

In terms of the SSD's, I bought my corsair ones a while back, which ever was cheapest at the time, then I heard the 850 was a real good one, and I needed a new one for more space so I bought that.

Lastly Corsair Link is a PoS I agree but I don't bother with that software, I've been using MSI Afterburner and my MB to check temps, and the Fan controller for general Idea. But the cooler itself seems to be working just fine.

Again sorry for the misleading posts assuming I was buying this PC from scratch, you all must be grabbing you hair be saying "wtf" hahaha.
 
WTF, aaaaaaaaaaaaaaaaaaaaaaa. JK. Anyhow, it doesn't really matter on the RAM. Corsair assembles pretty good modules. It's one of the few products they make that I think is rather well done. Of course, they don't actually manufacture RAM. They're an assembler, like Kingston, and like Kingston they're one of the better ones. Corsair buys memory chips from actual manufacturers like Micron and Samsung. They then assemble modules from those chips. G.Skill is another assembler.

Samsung, Mushkin, Crucial (Micron) and IBM all manufacture memory chips for RAM modules. I tend to stick with memory made by Corsair, G.Skill, Mushkin, Kingston, Crucial, IBM and Samsung. Other brands like PNY, Patriot, Adata and some others might be ok for lower end or mainstream units but I avoid them for enthusiast machines. The Corsair Dominator and Vengeance series modules are perfectly fine, I just don't see the point of paying for the Dominator series modules when there is really not that much to be gained over the less expensive lines unless you plan to overclock the RAM with custom cooling or need fancy lights and heatsinks, most of which is for the "bling" factor and doesn't really offer a lot of real world performance gains.

Okay so I've re checked the pc list and my pc/newegg order history.
I have the Hero VII not VI if that matters.
I'm currently trying to find the real fans and plugging that in.
The RAM I was going to look for is Vengeance Pro, 2400 or the second one down.

So can we talk in detail on why exactly it flagged me on what it did, what that would it do if I bought and used it, and how to go around it if possible? (the 2400Ghz)
 
There's nothing to do. Just go to the store where it shows the best price on the modules you want and buy it. PCPartpicker also has the "ignore compatibility" option because they know their default cross reference isn't always accurate. I guess I'm not sure what the problem is you're having.

The 2400mhz will probably, almost certainly run, but everything you do that increases or uses higher voltage tends to shorten the lifespan of components to some degree. This is why modern hardware is going the other way, with tendencies towards lower voltages, as well as to reduce power consumption.

Okay so it isn't a "you'll blow up your computer or parts" warning but more of a "hey be careful this could be a problem"?
I'd like some high speed ram, as not only gaming I use a lot of software too, as a game designer. Is 2400 going to be okay with an i7 4790k and Hero VII, using the BIOS to overclock it for me, using the tuning wizard ASUS provides.
 
It would actually be worse, as the 2400mhz modules are certified for higher clock speeds and the necessary voltages required to run them at higher speeds. That doesn't mean it won't WORK, it would just be better to actually get the speed you want to run. I don't see any advantage to running 2400mhz modules over 2133mhz modules anyhow. The only performance difference you're likely to see will be in benchmarks. There will be some minimal benefit to a faster module, but not enough to warrant the possibility of problems. Unless you simply want to "see how far I can push this baby 'til the engine blows", I'd just stick with the 2133mhz modules which WILL give you some benefits over your current 1333mhz modules. That's just my opinion though. Some guys just want whatever gains, however small and at whatever risks, they can get.

2133mhz minus 1333mhz equals 800mhz difference. 2400mhz minus 2133mhz equals 267mhz difference. Not enough to matter really. Plus, I think at about 2133 you reach somewhat of a Plateau where the gains per clock begin dropping off anyhow without also having a faster CPU clock speed and/or system bus speed.
