i9-9980XE shuts down using Linpack Extreme

Hi guys,

I haven't posted in a while but I've been battling with this issue for a couple of days now. I'm trying to overclock a 9980XE CPU but as soon as I change any BIOS setting relating to voltage or clocks the system immediately shuts down when running Linpack Extreme.

System in question:

Intel Core i9-9980XE
ASUS TUF Mark 1 X299 with latest BIOS
4 x 8GB HyperX Predator 3200MHz
Corsair H115i Pro
RTX 2080
EVGA G2 1000w

I can get the system stable to run numerous passes of Blender Classroom at 4300MHz with 1.1v, with the core temps maxing out around 75'C - 80'C, VRM temps 95'C max, so I know temps aren't the problem. As soon as I start Linpack Extreme the system shuts down without even trying to run, no BSOD, just shuts down. Seems like some kind of OCP.

So naturally I tried it with lower voltages and clock, same thing. I then realized that leaving all clocks and voltages on auto, but even just enabling "sync all cores", the same happens. Leaving the core ratio setting on it's default of "by core usage", and then using manual voltage of 1.000v - 1.100v (Auto voltage is 1.075v) the same happens. So basically any voltage or clock setting other than "Auto" causes this to happen.

I have some OC experience, but this is my first time OC'ing X299 so I was hoping someone could give me some insight as to why this might be happening. This build is for a customer and I can't have the system shut down every time AVX is used.

P.S. I also noticed that the power limit and duration settings have no effect when running all cores at 4.3GHz 1.1v. I deliberately tried to force the system to start throttling at 200w since this is the limit of what the VRM heatsink can dissipate on this board. Even when reducing the long duration power limit to just 150w I could not see the CPU downclock as I expected it to.

Try splitting the EPS cable, can be the OCP triggering in. I also think this motherboard is to be changed straight away :v. It's not even I think it is to be changed - IT MUST be changed because this motherboard is trash.

Setting SVID support to "Enabled" now allows me to use the power limit settings to throttle the CPU.

It was on Auto before which I assume disables it when the board detects non auto settings are being used.

Going to play around with this a bit

Hi,
Those temps on 4.3 are pretty bad actually
Thanks for reminding me why I added a water block on my vrm's 95c at 4.3 is why and I'm on a mark 2 doubt any of the first generation boards had very good vrm coolers

2nd gen boards do have a lot better vrm coolers but are pretty much 5-700.us as well.
x299 Prime deluxe 2 = 500.us
x299 omega = 700.us

So there are your options 2nd generation board stay on the same bad cpu cooler
Custom loop with vrm water block with the same board you have.
Either way 500.us is about what it takes.

OK, so with actually being able to use the power limiters I was able to get the CPU running stable at 4.3GHz. Short duration power limit was set to 350w and long duration to 280w.

280w on the long duration power limit keeps the VRM's under 90'C and 350w on the short duration keeps the core temps under 85'C. Any test such as P95 Small FFT's will make the CPU throttle to adhere to the 350w limit and then after 127sec throttle even more to 280w. Light workloads will still see the full 4.3GHz on all cores since they wont hit the power limit that's set.

The board is certainly the weak point and I regret not getting a better board, but so you learn.

This CPU can easily do 4.5GHz but the OCP on the board gets triggered before the power limiters can kick in so the system shuts down. On 4.3GHz this does not happen.

I also used Auto voltage and let the CPU run on it's predefined voltage table. This allows the voltage to throttle in step with the frequency to maintain the power limits I set. If using manual voltage, the specified voltage is kept across all frequencies and therefore running anything AVX based will instantly trigger OCP. With Auto voltage the voltage decreases in accordance with the negative AVX offsets which I set and therefore does not trigger OCP. I had to be aggressive with the AVX offsets, AVX512 offset was set to 13 (3.0GHz) and AVX offset to 5 (3.8GHz).

This was frustrating and enlightening at the same time. I can see benefit to being able to target a wattage instead of a frequency when doing an overclock. If you don't happen to have the best cooler or custom loop, you can just target whichever wattage your cooler can handle. Or as in this case, the VRM can be kept in mind when targeting a long duration wattage if your board has crappy VRMs.

Any thoughts/opinions on the Gigabyte X299 AORUS MASTER motherboard? It's a better price than the Omega board, but still seems to have very decent VRMs and 2x8pin EPS.

Unfortunately none of those are readily available in my country.

Then you'd best import one of these boards from abroad if you don't want persistent issues.

Hi,
You might make sure the ECO switch on the 1000w G2 isn't turned on that would likely cause a shut down.
4.2 on 9940x usually takes 1.12v but yes auto voltage is evil

Adaptive with auto offset and additional turbo 1.1v might be more forgiving than manual.

An item to usually tame is Input voltage it can get upwards of 2.0v where 1.80-1.90v is usually plenty for that low of a clock.

Thanks for this response instead of just saying "get a better board". I've been overclocking since the days when I could not afford the best components on the market and tought myself how to get the best OC out of the hardware that I had. With this build I do not have the luxury of changing to another board due to several reasons, hence I'm asking for help in order to understand this platform and it's limitations/nuances better and make the best of an unfortunate motherboard choice.

So on to your suggestions:

1. ECO switch is OFF

2. I tried Auto Adaptive offset with 1.1v addional turbo but it ends up at the same 1.235v @ 4.3GHz as it would with Auto voltage.

3. I can see Core, Cache, VCCIO, SA and PCH Core voltages in the BIOS, but no VCCIN. Under Tweakers Paradise there is an option for "CPU Input Reset Voltage" and under External Digi+ Power Control there is "CPU Input Boot Voltage". I tried setting both these to 1.8v but the reading in HWInfo for VCCIN is still ~2.0v. Not sure if I'm missing something obvious?
In this guide the CPU Input Voltage is just under "Uncore Voltage Offset" but on the board I'm using there's nada
