As in most electrical components, however, CPU voltage requirements don’t exist in a vacuum. Vcore and CPU BasicsĬPU chips are designed to operate at specific voltages. Here’s why Vcore, or the core voltage of your CPU, is such an essential part of performance tuning. CPUs are designed with specific operating parameters in mind, so you’d be well-advised to accommodate their needs. Of course, that doesn’t mean you can merely dive into the BIOS and change settings at random. Thanks to increased interest in customization, it’s now far more common. Overclocking, or the act of speeding up the native rate at which your CPU runs, was once the sole domain of gamers and overworked workstation owners. I'll probably take it lower to get it within 10% of its rated wattage/Vcore but for now I'll leave it at -110 and start running tests on the cooling itself to shave off points there which will then actually lower wattage a little more on its own.If you visit the web’s most widely read computing tech blogs, you’re almost guaranteed to run into a common theme: overclocking. Absolutely stable at -110 considering the CPU itself was pre-tested at even lower Vcore/wattage across three motherboards before using. 3 of the keys stay mildly lit up red even when turned off.
I think the keyboard might have a lighting problem like another member had in the SM forum. X16 memory instead of x8 (while they are selling hundreds of x8 modules on eBay.boo) The original CPU thermal compound got away from the original tech and was all over the CPU guard and on some of the pipes I would also delid it and put a copper or nickel plated copper IHS on it. I'd also take a look at your cooling, thermal application, heatsink evenness, test spread pattern, etc. If I had your CPU to test, I would pop it in my Asus board, get its rating and at the same time test its V/F curve against what it actually needs to pull and use that as my baseline to then dial in your undervolt. I'll probably take it lower to get it within 10% of its rated wattage/Vcore but for now I'll leave it at -110 and start running tests on the cooling itself to shave off points there which will then actually lower wattage a little more on its own. This thing needs Prema stat or at least Dsanke to unlock some of the settings.Ĭlick to expand.No delid. That will leave some room for some overclocking but my primary goal is to have it run stock cool as possible to bring the fans down to being silent except when gaming or compiling. I expect to shave another 8-12 degrees off these numbers when all is said and done.

I haven't even begun to tweak and mod the heatsink and do extensive pairing tests, test an array of shims, 2-3 different compounds or mod the bottom panel to bring it down even further.
This is how your X170KM's should be running at a minimum and this is with the hottest of the 11th gen chips.

I know I can probably apply up to a -130 to -150uv based on the quality of the chip and how low it can go but this allowed it to run without any throttling full tilt (I sat there staring at the clocks while it ran) and zero flags tripped: Knowing it's range I whittled it down to a conservative -110 UV which translated into a reduction from 226w down to 182w.
#Sager bios vcore install#
I knew there were going to be problems as soon as I did a stock install run with the included 11600k and it was hitting 90 in CB23.Īs soon as I installed the 11900k into the it X170KM-G (and adjusted the performance settings to give it all it wanted) it immediately wanted to pull 226w which is beyond overkill and was of course thermal throttle city as it was pulling ~40w+ more than it needed at the minimum.Ĭmos reset and clean install was first to remove any stock install/settings "what ifs" I did the same with my P870TM1-G and a 9900k so I knew exactly what the chip needed after having run it on multiple motherboards to dial in its requirements so when I moved it into my P870TM1-G I had a target. The 11900k I'm using is an SP93 very quiet cool running chip that having used it on 3 different motherboards I know it can run pure stock anywhere pulling from 163w up to 200w depending on the motherboard and that is when the auto settings are too aggressive.
