Hi everyone

Despite my research I did not find a solution to my problem.

System specs :

- Motherboard : Asus Z270-E
- CPU : I7 7700K delid
- Cooling: NZXT x62
- RAM : Kingston HyperX 2x8GB 3600Mhz (17-18-18-39)
- GPU : Gigabyte GeForce GTX 1080 G1 Gaming - 8 Go
- Storage: 1T SSD Samsung 860 Evo Sata
3T Seagate Barracuda 7200.14 SATA 6Gb/s
- Power supply : EVGA 750 BQ, 80+ Bronze 750W
- OS: Windows 10 PRO
- Dual Screen IIyama Prolite XB2380HS (game just on one)
- BIOS : 1302

My problem :

When I play it happens more or less regularly that I have freezed games and causes a return to windows. The moments and the duration between freezes are random. (Can happen in the loading screen)
I have no worries in windows or other software but just in game and no BSOD screen.
Basically I think it's a problem of RAM and XMP profile. I don't have any problems with XMP disabled. My ram is not listed in the QVL of the Z270E
Problem is the same with XMP Profile 1 and 2.
Under Furmark, 3DMark, PCMark or MemTest64 tests look good.

Do you know how I can fix the problem ?
Maybe I have to adjust manualy the RAM setup ?

Let me know if you need more informations

Thanks for your help

Well, it could be a few things, I suppose. Keep the overclock and try running a game under minimum graphical setting's. Test to see what happens. Observe if your game is stuttering.
What temperature's are you receiving when playing a game for the processor?

Hi dandan74

Welcome to the ROG forum.

Try setting:

CPU VCCIO voltage 1.15v - 1.25v
CPU System Agent voltage 1.15v - 1.25v

Try both at 1.15v first, if it's still freezing with both at 1.25v try bumping up the Dram voltage to 1.40v.

Thanks

First anwser about the temp, full details XMP off, Farcry 5 between 50-60° I7 7700k delid

I'm going to try to change the VCCIO and SAV voltage

Two more questions :
When I change for XMP profile, the BIOS ask me if I want to active the "All core enhancement", do I say Yes or No ?
With the XMP profile, BIOS also change CPU Core Ratio : Sync all cores to Auto and fix Frequency BCLK to 100, is it ok ?

Nate152 · ‎10-17-2018

1) Select No
2) BCLK at 100 is fine, you can change it back to sync all cores and set the cpu core ratio to 45.

Double check the cpu core/cache voltage is not on auto, if it is on auto try cpu core/cache voltage at 1.15v - 1.20v. It won't go below the core VID so you may have to use a negative offset to get the voltage that low.

Try setting the ram manually, this sometimes gives better results.

I tried : CPU VCCIO voltage 1.15v
CPU System Agent voltage 1.15v
XMP profile 1
RAM : 1.35V

Game crashed

Try to move to
CPU VCCIO voltage 1.20v
CPU System Agent voltage 1.20v
XMP profile 1
RAM : 1.35V

The CPU core/cache voltage is on auto. So I need to change it for 1.15 or 1.20 and use negative offset mode ?

I tried : CPU VCCIO voltage 1.20v
CPU System Agent voltage 1.20v
XMP profile 1
RAM : 1.35V

Game crashed

I tried : CPU VCCIO voltage 1.25v
CPU System Agent voltage 1.25v
XMP profile 1
RAM : 1.35V

Game crashed

Now I set :
CPU VCCIO voltage 1.25v
CPU System Agent voltage 1.25v
XMP manual - 17 - 18 - 18 -39
RAM : 1.40v
BCLK : Auto
Ratio : ?

At tthe moment I didn't change the CPU core/cache voltage, still on auto.
To change it, I need to set 1.15 or 1.20, use negative offset mode and "-" sign ?

Last setting, game crashed with BSOD

Any suggestions ?

Try resetting to defaults (F5), set the AI Overclock Tuner to Manual and set your ram manually.

Try Dram Frequency 3000MHz and slowly work it up.

In DiGi+ set LLC to level 6

Once you get the ram stable then do the cpu, try cpu core/cache voltage at 1.20v. You'll have to do a little math, for example, if you set 1.20v and it's going to 1.245v, you'll use a negative offset of -0.045v.
