Question: Should i get this for use with ASUS MAXIMUS VII HERO + i7 4790k? Or its better to use a 2400Mhz instead?
Document: This is my first time to use memory sticks that have fin and led. They are working fine and look cool with the led lighting.Good dedign and craft. I like it.
Of course I knew it was the RAM so I re-booted into my ASUS P8P67 Pro Rev 3.1 EFI Bios. From there I noticed that my frequency was at some odd number like 1368 MHz and the only other options were over 1600 MHz and under 1600 MHz.
Best corsair ram you can get. Easily clocked to 1600 mhz no prob. If you're looking for top quality ram thats not DOA and dont mind spending a  little extra, these babys are where its at.
Here is so far what I gatheredPeople here have said it had issues or product given not as claimed.My understanding told me these are 1333MHz stock all memories comes in like that especially the higher MHz you find nowadays. You get 1600MHz because you have to OC it to that point via BIOS (old days) or UEFI for it is proper name for the tech used.
Again I have the ASUS P8P67 Pro Rev 3.1. So ultimately after installing my old RAM and reading through a few more forums I ended up installing the newest BIOS v3602 onto my mobo. Once I installed it I retried the RAM and NOW I have no issues thus far. Please allow a few more days of testing. Updating my BIOS really solved a lot of boot problems that I was unaware of. Definitely more stable now. :)
I was planning to get another set but due to limited stock the price jumped almost 15% soon after purchase. Waited for stock levels to catch up and ever since the Platinum has continued to rise. Meanwhile there is only one reliable source (which is not Amazon) for the light bar (color) kits and other (Link) accessories. I expected Amazon to be fully stocked on color bars long before now.
I saved and restarted the computer into Windows 7 and I had no glitches. I then turned off my computer and added the other stick of RAM and booted my computer with my fingers crossed. Windows 7 started up with no problems which I forgot to mention earlier at one point Windows was stuck on the loading screen for like 2 minutes which for my computer is very unusual (look at computer specs below. )Now lets get to the good stuff!
I want to start by saying this product is not for people who pay Geek Squad to solve all of their problems. I received this RAM for Christmas and installed it the same day. I normally start with one stick of RAM to make sure everything works but of course it was Christmas morning and I had several other gifts pertaining to my computer that I wanted to get to. I slapped the two sticks of RAM in my computer and booted into Windows 7 Ultimate 64 bit.
So it seems Amazon is telling me to basically shop elsewhere if I want real selection where real customization is concerned. It's understandable that not everyone buying this ram is an Enthusiast but Amazon can honestly do better.Now for the biggest and only con (IMHO) is that Corsair simply is not on top of the game anymore. Support is no where near the same level it used to be in years past.
Everything about this 16 GB RAM kit screams premium. The heat spreaders are thick and heavy. I have a Noctua NH-U12 S cooler whose fan stops just short of the extended spreaders.The Core i7 4770K CPU and ASRock Z87M OC Formula motherboard reads the default timings of this kit as 667 MHz (1333 MHz for Dual-channel).
Answer: I tried going with 2400Mhz for that very same setup and it turns out that the RAM voltage on the sticks was too high for the CPU. I went with 1600 afterwards and everything is stable again.
