Games crashing when using XMP profile 2400Mhz

[HristijanP]

Hello Guys,

I have an issue when using the XMP profile for 2400Mhz. Configuration below:

- Asus ROG MAXIMUS VII RANGER
- Intel i7 4790k
- CoolerMaster Nepton 120XL
- Kingston HyperX Beast 2400Mhz - Part Number: HX324C11T3K2/16
- Asus STRIX GTX 970
- Samsung 850 PRO 256GB & WD Blue 1TB
- CoolerMaster V650

More details an the issue. When i use the XMP 1 profile with 2400Mhz, games start to suddenly crash. The screen just goes to Desktop and i am not getting any errors. This is occurring randomly and i haven't spotted any pattern. The game in question is CS:GO.

I have reverted the RAM settings to Auto, therefor the frequency is set to 1600Mhz and i am not having any issues at all. I haven't had a single crash in the past 2 weeks. Everything seems to be working smoothly. I have also tried the second XMP profile with the 2133Mhz, and i am getting the same situation as with the 2400Mhz settings. I guess it is some instability issue which occurs on time to time. Also, i have performed a memtest and i have not received any errors.

All other BIOS settings are set on Default and my CPU is not overclocked. Also, i have updated the BIOS to its latest version.

Any suggestions? It is really sad when you get a high performance ram and you are using it as a regular one.

Any help would be really appreciated.

Thanks.

That ram kit should work with your motherboard I see other users in reviews using it with z97.

Try using the other two slots and see if it's any better. It should go with what you have in your screen shot, if it still doesn't want to go try 12-14-14-32-2T timings just to see if you can get it to play CSGO without freezing.

Before doing this try setting the vccio and cpu system agent voltages to 1.20v - 1.25v.

Well, i tried setting the same settings manually like i did previously, but using the other two slots - still, crashed after 5-6 mins.

Than, i took your advice about setting the VCCIO and system agent voltages, but i was not sure what exactly needs to be changed... 🙂 Sorry, just wanted to make sure i am not changing something i am not supposed too.

The screenshot below is taken before i revered all the changes again and LOAD OPTIMIZED DEFAULTS.



I still don't get it, why the DRAM voltage is 1.665V, even tough i set it to 1.65V.

In any case, which two settings are corresponding to the VCCIO and System Agent voltages? "CPU System agent Voltage Offset" & "CPU Analog I/O Voltage Offset" ?

Your bios might be different and you use offset to adjust it, I'm not 100% sure though but you could try using the offset.

It shows the cpu system agent voltage at 0.944v, raise the offset +0.20v. This should put the cpu system agent voltage to 1.14v, if you have the vccio voltage option set it the same at 1.14v.

I'm hoping this helps you, fingers crossed.

I have found that this issue is directly related to the power supply. Basically, when you are using enthuisast memory you have to have a superior power supply. I suspect the power supply is being stretched and isn't delivering the quality of DC power that memory requires. For an indepth review of that power supply, see here: http://www.hardocp.com/article/2014/07/24/cooler_master_v650s_650w_power_supply_review/9#.Vr8f0zH2Zo...
