Overclocking DDR4 to 2400Mhz

[Greggers]

Soo, I built myself a new rig. Specs below.

 

http://www.scan.co.uk/savedbasket/a109cdb8-da4f-4943-9854-3263d16d5f12

 

Having issues overclocking this RAM, the best I could get from it is 2200 Mhz using the following settings. 

 

tCL = 16

TRCD = 16

tRP = 16

tRAS = 49 

 

Which, seems a bit high. Enabling XMP just craps out saying that the overclock failed, however, if I remove one stick of RAM and leave one in it works fine, both sticks work if they're in on their own. 

 

Rang scan support and they essentially went yo dawg, bent CPU pin. Bollocks to that, I was extremely gentle, even as far to wear rubber gloves so I know the pins aren't bent. 

 

Anyone know of any issues with this mobo, RAM or any other suggestions? 
 

Also updated the bios, no difference :'(

Whilst i don't have a fix for your problem, why are you bothering to OC your ram? You gain practically no performance gain in real world performance.

[Greggers]

Well, my RAM is rated for 2400 and is currently running at 2133. Why not if it should technically work, I want it to work .

Then just go into the BIOS and set it to 2400mhz. Then it is not overclocking

See that silver medal I have? OCing RAM from 2133mhz to 3200mhz got a 35% increase in a task that over a week of continuous processing. While OP probably doesn't use the same app that I do, I still wouldn't call it "pratically no performance gain in real world".

 

For gaming, yeah, you might be right, but that is not the only thing people do with their PCs.

 

OP: What are the default timings for your ram?

 

Stock Timings + Frequency won't work? Try raising the voltage a little bit, see if that fixes it.

Have done, just says overclock failed still.

The default at 2133Mhz were 15-15-15-36 but I believe I need to hit around 14-16-16-31 according to the spec sheet and it just crapshoots if I try it.

Why didn't you go with 3000Mhz ram or higher in the first place.

 

The Corsair Vengeance LPX CMK16GX4M2B3000C15 is 155€ for 16GB here, not that much more expensive then 2133/2400

Would that have even worked on my mobo? 1st PC build, previous ones were all salvaged crap from other PCs but I was under the impression that I'd need to oc to get to something that high.

Tried the voltage at 1.25v, no potato

Well DDR3 with no overclocks go up to 3600Mhz now.

And again... With DDR4 this comes up so often... When a RAM kit is rated to run at a certain speed, that is only it it is rated to do so, it doesn't mean that it will. It all depends on the memory controller on your processor and the motherboard you have. Early BIOS revisions also tend to not feature a big DDR4 comparability. Try updating your BIOS. If it is already, check regularly for updates, perhaps that will solve the issue over time. Pumping more volts through your RAM will do nothing, believe me I know so don't waist your time with that.

 

You can also try running the RAM at a speed higher than 2400MHz. Perhaps 2666MHz and see what happens. Worst case scenario you will need to clear your CMOS. My RAM is rated at 3000MHz, but it doesn't work at that speed, because XMP 2.0... However, after some tinkering around with timings and command rates I did get it to 3333MHz without issues, using the same 1.35V volts...
