7920X x299 OC stability fail

Hi everyone,

I am having an issue with my new rig. I decided to go all out and do a complete custom watercool rig. I have the aorus gaming 9 by gigabyte.

Essentially I am having massive stability issues. I cannot OC this thing without getting the whea error or just random lock ups and shut downs. Here are my settings:

1. Enter advanced frequency settings.
2. Change CPU Clock Ratio to 45-47.
3. Enable XMP
4. Enter Advanced CPU Core Settings
5. Set CLR (MESH) Ratio to 32.
6. Set Enhanced Multi-core Performance to Enabled.
7. Set Energy Efficient Turbo to Disabled.
8. Hit ESC twice then enter Advanced Voltage Settings
9. Enter CPU Core Voltage Control
10. Set CPU VRIN External Override to 1.9
11. Hit F10 to Save and Exit.

Any help would be appreciated! Pic of PC included.

Hi,
Did you delid the 7920x ?
What are your temperature spikes ?
An 850w psu isn't actually enough for skylake x and without a delid 4.6-4.7 is a dream
4.5 will also be hitting pretty close to thermal limits
If you see an option to use by core enter 4.5 on the core listing with an * next to them and 4.0 on all the rest.
Also cache/ mesh leave at 30.

It is not delided and I am hitting a high of 65c with this loop. Do you think I could be having a power issue with my psu? I had not considered that.

Hi,
Watch the video man states x299 sucks up the juice
I believe 1000w was said to be a minimum for this platform
So again if you see by core or by core usage use that instead of all core.

850w would be for cpu's under 7900x

850W or 1000W is ridiculous and unnecessary for ambient cooling on this platform. I have an i7-7820X running at 4.8 GHz/1.25V on a 650W 80+ Gold SeaSonic PSU, and I'm barely pushing that considering the CPU pulls <300W under full synthetic load.

Unless you have a PSU of terrible quality, your power supply is not the issue.

I bet it doesn't like the 32x mesh setting.

This doesn't really change your point, but I'll point out that the 7820X isn't the same as the HCC chips. My 7940X @ 4.7 GHz will easily pull 380W under ambient - not delided.

I imagine that a delided 7980XE under a custom loop could probably draw 500W+ under ambient.

Start from stock 24x and work up from there. From my experience with 3 of these HCC chips, none of them were stable at 32x with default voltages.

Start at the stock setting, increase by +1 and see at what point the WHEA error pops back up.

I would do the Core multiplier independently of the mesh so that you can find the max for each.

380W is considerably lower than 850W or 1000W. Even if you assume 500W of power consumption with the i9-7980XE, that's not even close to requiring a 1000W PSU.
