Hi guys. I'm looking for your help.
I would like to know why I have Current/EDP limit throttling on my processor intermittently and how to fix it, even with stock values, without any modification (Only in Bios ASUS MultiCore Enhancement = Enabled - Remove All limits).
I have an i9-13900K on a Z690 Maximus HERO with 128GB RAM @ 4200MT/s powered by an Asus Thor 1200P. The system has excellent temperatures (Thanks to a Galahad II Trinity Performance) even at 100% load.
I already know that these are the 3 reasons why Current/EDP limit throttling happens.
1. Processor Core IccMax is set too low in the Intel® XTU.
Processor Core IccMax is set to Ulimited by defaul. I don't consider unlimited to be too low a value.
2. VR (voltage regulator) current limit is set too low in BIOS. Different motherboard OEMs may have different names for this control. Contact your motherboard vendor.
3. The motherboard is not able to provide high enough current for the given processor. Pairing a low-power motherboard with a very high Thermal Design Power (TDP) chip can cause current/EDP throttling, even with current limits set to the maximum.
The 13900K is mounted on a Z690 Maximus HERO, which is clearly a powerful motherboard that can match the amount of power needed for the processor. The motherboard is powered by the two 8-pin cables ATX_12V_1 and ATX_12V_2 so this is not the reason for the failure.
Does any of you know how to fix Current/EDP limit throttling?
Beforehand thank you very much.
