Alder Lake undervolting is broken in a weird way: intel is run by blind drunk monkeys
During a remote tuning for a client using i7 12900k on a b760m aorus we found out that every bios would engage in clock stretching when undervolting the CPU, without any option for the 104 microcode avaiable
i finally have the opportunity to test myself and can confirm that undervolting is broken on b760 but only for i7 and i9 SKUs, even i5 12600kf is working fine, like every other i5 i tested based on the C0 die / stepping .
This is totally counterintuitive (you should get more options and toggles the higher you go in the SKUs tier) and results in massive efficiency advantage for i5, that can deliver 80% of the multicore performance while using exactly half the power!

Asrock b760m Alder Lake clock stretching when undervolting
มุมมอง 4621 ชั่วโมงที่ผ่านมา
After my MSI experience i wanted to test this Asrock super cheap ddr5 dual dimm board, hoping to get better results from my 12700kf and 64gb 6400 kit, but i was disappointed. The RAM refused to even post and the unlocked CPU was clock stretching even when CEP was forced disabled in the bios. C0 locked i5 was the only CPU to properly undervolt without performance loss.
World backwards: locked 12400f vs unlocked 12700Kf Alder Lake on MSI B760M Mortar + shitty RAM kit

Alder Lake has been a very good cpu arch for intel - arguably, their only real smash hit and notable single core performance improvement since Sandy Bridge, and this is why it is still relevant today. Clock stretching has been one of its few issues, mostly because they don't seem to have any clear explanation on who and how can disable it. L ast week i found out that on MSI boards i could not g...
Ryzen 3100 undervolt and Micron 4Gb B Die 2133cl14 overclock to 3200cl16
มุมมอง 6014 วันที่ผ่านมา
Cheap build tuned for performance and efficiency with 2x8 2133cl14 running at 3200cl16 Ryzen 3x000 undervolt gets to clock stretching, the offset was tested tongive the best results using most benchmark software like Linpack, YCruncher, different Cinebench and Geekbench 6 Vsoc at 0.83 means very low idle power consuption aswell
Alder Lake undervolting is still relevant and still a crazy mess - channel update, future content

in my first channel @mircomputers i have posted a dozen of videos related to Alder Lake undervolting, delving into the issue of clock stretching triggered by CEP depending on the motherboard and the different H0 and C0 dies , locked vs unlocked chips and so on MSI had a huge advantage with Lite Load working on the sweet H0 While i thought i found some patter, now in late 2024 everything turns o...
Red Bios Editor is a miracle for Polaris undervolting
มุมมอง 4821 วันที่ผ่านมา
have been waiting for a tool to undervolt Polaris in bios since 2019 when manual voltages stopped working on PolarisBisoEditor The tool is super powerful compared to everything else that came before it, and i suspect some functions support depend on the voltage regulation on the target card you are working on; so far the result i got on my 580 2048SP have been mindblowing.

A tour of my refurbishing project on this tiny 7th gen intel machine, with a very slow and low poer Pentium G4560 that is throttled to even lower clocks by the 65w adapter. Wiring the WiFi was a huge PITA. These machine have to come free if the wifi is not installed already, otherwise they canno compete with used notebooks value, being half the performance of 8th gen i5s like the 8250u and high...

Preventing Flexgate on MacBooks - add tape to increase cable strenght

New test on Flexgate - how to prevent it from happening. Testing on already broken cable shows improvement, wich gives good hope for its straightening and strenghtening effects. Previous test, probably not useful in the end: th-cam.com/video/0KxSyrrA168/w-d-xo.html

Where did u put the tape exactly? I have a 2016 mbp 13 inch touchbar model with flexgate issues and trying this trick to get some improvement on it
I have a chinese RX 580 ( 2048SP) ..The fans are too loud and cannot be lowered below 2K RPM .. The red bios editor cannot open the bios file .. Whenever I use polaris bios editor to change the fan curve the card gets error 43 .. Something to do with driver signiture being lost after writing .. Any suggestions ?
@@technomad900 that is very very strange, i never had this issue with loads of different chinese polaris mining cards back in 2019/202 using PBE, did you try to find info on the PCB and cross flash with another bios of a similar card?
What is the power plug size of this? 4.5mm x 3mm?
@@StefanDim the small Dell one, same as the XPS machines
And that, ladies and gentlemen, is how you eke out every little ounce of performance from a system!
well, the first generation i7 were clocking like crazy, i could have gone that way with the system but i have no trust in the PSU 😅 i also feel smooth stable 80fps in fortnite is perfect

Run this game for like an hour and your hardware will probably get irreversible damage.
