What RAM should I buy for ASUS H97-Plus with i7 4790?

davidbenpark · Oct 4, 2014

I just bought an i7 4790 CPU and an Asus H97-Plus mobo.

I was all set to buy 16gb Trident X 2133mhz but after a bit of Googling I'm not sure if that RAM is right for my cpu/mobo combo.

The ASUS documentation says that "on XMP mode memory modules will run at the maximum transfer rate of 1600mhz." Does that mean there's no point in buying 1833/2133/2400mhz RAM?

There's also the 1.5V issue. Is it right that if I'm not overclocking then the extra V's might damage my CPU? And will the warranty be void?

4 x DIMM, Max. 32GB, DDR3 1600/1333 MHz Non-ECC, Un-buffered Memory *

Your board supports up to ^

Does that mean there's no point in buying 1833/2133/2400mhz RAM? YES

Wow...that sucks right? Can I get some mega awesome 1600 RAM with really low CL to make up for it? Or should I cancel/upgrade the mobo?

You wouldn't notice a real world difference anyways.

The Tridents suggested by SR-71 are what I'd suggest also, great sticks and lots of OC headroom. Even w/ your mobo, good chance you can run them at 1866, if you decide to try, give me a shout

Tradesman1 :

Excellent - I found them for a good price on Amazon. Thanks a lot for the help - sorry for newbie error! After the build is done I may be back to ask how to run them at 1866!

We'll be around, C U then

We are glad to help thanks for posting.

Sorry to pick up this conversation again but I decided to cancel the H97 mobo and go for a Z97 mobo (probably the ASUS Z97-A) so I could get the faster RAM. I think the faster RAM will be sensible for the kind of applications I intend to run.

Your advice was great but money isn't an issue so I didn't want to get something that would limit me over time.

Hopefully it's the right choice!

If going that route, then get the K model, might not want to OC now, but down the road it's like getting a free CPU upgrade

and the Z97-A is great for OCing

davidbenpark · Oct 5, 2014

Tradesman1 :

Will I need the K processor in order to OC the RAM? Am I right in thinking that when you buy 2400mhz ram, you're technically still buying 1600mhz with more headroom to OC?

Tradesman1 · Oct 5, 2014

For 2400 sticks good possibility it will take a slight OC of the CPU to run them at 2400, the memory ICs are tested to run to run at 2400, so it should be simply enable XMP and be good to go

davidbenpark · Oct 5, 2014

Tradesman1 :

What if you don't OC the CPU at all? Would you expect the RAM to play nice at 1866 or 2133?

Tradesman1 · Oct 5, 2014

With most of that CPU yes, the 2400 is where it tends to get iffy with the CPU at stock
