Corsair Veng issues with i7-4790k

[Programz]

Okay, so, while playing one specific game, (PUBG) when I used X.M.P profile settings with my RAM, I would get constant crashes and couldn't keep it going.

I've since down clocked my RAM to 2000mhz, and it seems to be running stable for everything I'm doing. However, being as its 2400mhz RAM, I feel I'm getting let down on performance (I know it's not much) but I'd like it to be at 2400mhz. Can anyone assist me in figuring out I/O settings, or getting this set correctly so I can run at 2400Mhz on this ram?

i7-4790k
Corsair Veng (2x8gb) CMY16GX3M2A2400C11R

I'm either missing something, or the game wasn't fully optimized at the time and would just over do my RAM and send me into a game crash. I haven't tried resetting back to XMP in a long time, but the game is a little more optimized now so maybe it wouldn't have as many issues.

Any information would be helpful.

Thanks!

Have you tried setting memory speed, voltage and timings manually?

I have, still usually end up with the same problem. I'm curious if maybe the voltage settings are too low, but on the sticks themselves it says 1.65v, and I can manually set them to such but still has the same problem.

Supported memory for i7-4790k is DDR3-1333, DDR3-1600.

If you are going to buy overclocking memory, 2400MHz, then don't bother to overclock the system you can expect crashes and unstable performance when using 2400MHz speed.

Ah, I wasn't overclocking the CPU or anything, just trying to do the RAM. So basically I'm SOL? Lol

I'd be more opt to buy some low latency, 1600mhz then?

Intel considers 1.575 Volts to be the maximum safe memory voltage. Intel says that anything above that is done at your own risk and has the potential to damage the integrated memory controller on the CPU.

I use two G.Skill F3-2133C11-8GXL 1.5V DIMMs on my ASUS Z97-PRO GAMER with an Intel Core i7-4790K and only use manual setup for the memory. I have no problem running at 2133 MHz with tighter timings than specified in the SPD table.

What does your DIMM's SPD Table show? Here is an example of what I'm talking about:

Right now its at (after tweaking)
DRAM FREQ 999.8 MHZ
FSBRAM 1:10

What memory voltage? Auto will default to 1.5 Volts. That voltage may only allow you to reach 1000 MHz (a.k.a. DDR3-2000). I would have expected that your memory should have been able to reach a DRAM Frequency of 1066.7 MHz (a.k.a. DDR3-2133) at 1.5 Volts with 11-11-11-27-2T timings.

To be able to reach a DRAM Frequency of 1200 MHz (a.k.a. DDR3-2400) you would definitely need to increase the memory voltage up to 1.65 Volts.
