Because HPC turns off power saving only when under heavy load, the chip can still down clock and downvolt during idle or light use while HPC is enabled and other features like cooling and quiet mode are active. It’s a smarter approach than completely disabling power saving. You don’t need 6 cores at 4GHz+ just to browse or watch videos. If you keep it at 4.2GHz on 1.368Vcore with HPC off, enabling it to 4.3 should work for a few more minutes. The LCK is set to medium; switching it to high might affect longevity, but it doesn’t seem to matter much right now. I bought this recently on a low budget and plan to use it for at least a year.
I've been operating at 1.38v for over three years on a 6300. As long as temperatures stay within the recommended range, it shouldn't affect the CPU's lifespan. To accurately measure load voltage, run cpu-z alongside stress tests; the voltage displayed under full load reflects the real value. The LLC can adjust core voltage in the BIOS to maintain stability during heavy use. With a 1.36v setting and medium LLC, you're more likely to achieve close to 1.38v. You were correct about choosing a high-quality motherboard—it makes a big difference. Many people cut corners when budget is tight. A 4.3ghz processor usually works well before needing significant voltage increases. Personally, I prefer keeping the load below 1.4v in cpu-z; beyond that it may harm the CPU's longevity.
BTW - verify your voltage in cpu-z relative to core voltage in bios.
If it matches what you've configured (or is slightly higher), just leave llc as it is and raise the core voltage a bit if you want higher clock speeds.
All that's needed is to remove any voltage drops under load, nothing extra required.
Since the u3p already offers very good voltage regulation by default, this should suffice.
Additionally, verify the voltage on the CPU-Z against the core voltage in BIOS. If they match closely or are slightly higher, keep it as is and raise the core voltage a bit if you need faster clock speeds. Just ensure the LLC remains unchanged; it only needs to avoid voltage drops under load. The UD3P already offers very good voltage regulation by default. Currently, at 1.38V and 4.2GHz, the 20-minute test in Prime95 passed, but rebooting causes crashes. After entering BIOS and increasing the voltage, it works again after a restart. I’m currently at 1.392V with 4.2GHz, booting multiple times without crashing. I’m unsure what to do—please help.
I’ve applied the default settings for now, just to avoid complications. It seems every time I enter BIOS and save changes, it crashes again. When I restart, it works fine. I reached 1.393V but didn’t go further, so I stuck with defaults.
When you obtain a working setup, it’s wise to save frequently. You possess around ten distinct profiles in the BIOS, which prevents repetitive work and is a solid habit to adopt. Overclocking remains largely experimental, and crashes or instability are common realities.
The UD3P supports dual booting the BIOS, making it extremely reliable—only about 0.01% chance of failure after several incorrect initializations.
I plan to review my configurations at a later time, possibly tomorrow, and I might post updates if I find something valuable.
For now, I recommend keeping all power-saving features active by default, disabling turbo, raising the clock speed to 20x, maintaining the original voltage, and turning on HPC as advised. Set the LLC to medium. I’m confident this will deliver stability immediately and offer a noticeable improvement over the stock version with minimal changes to voltage or temperature.
You should be conserving profiles once you have a working setup. With around ten separate saveable profiles in the BIOS, you won’t need to repeat everything. It’s a smart habit to adopt because overclocking is mostly trial and error, and BSODs or crashes are common. The UD3P includes a dual boot BIOS, making it nearly impossible to make mistakes—it will revert after a couple of failed boots. I’ll review my settings soon; maybe tomorrow, and I might post again if I have something valuable to share.
I’ll be certain to keep all power-saving options on, disable turbo, raise the clock speed to 20x, and leave voltage at the default setting. Enable HPC as suggested before. Set LLC to medium.
I’m confident it will run smoothly right away, offering a significant improvement over stock clocks with almost no change in voltage or temperature.
Now I’ve followed your advice—probably around 1.3625V for the default setting since it was noted after turbo was enabled. When turbo is off, it drops to 1.25V, so working at 4.0GHz with that voltage seems unlikely. I’m currently testing stability at 4.0GHz on 1.3625V and will share the results later.
It's always possible until you've given it a shot, buddy. I'm using an [email protected] on less than the default voltage.
It's never too hard until you give it a shot, I'm using an [email protected] on less than stock voltage. At first I left the voltage on auto and it didn't work, so I increased it to 1.3625, and now when running prime95, cpu-z shows the voltage at 1.392 and 1.38 during full load. Temperatures are around 43-45 max at full load.
It's never too late to give it a shot, buddy. I'm using an [email protected] on less than stock voltage. Any updates?
I followed your advice and it seems stable. I was running Prime 95 for over an hour with 75% memory usage, and it worked fine. Now I'm trying to boost the speed a bit more. Still unsure what caused the crashes, so if you can help, that'd be great!
