Looking for assistance with CPU overclocking?
Hello, this is my first attempt at overclocking and I'm unsure about the right voltage settings. I've attached pictures of my current configuration, but I had to increase the voltage from 1.3v to 1.35v because the system would crash at that level. I'm doing a test now to ensure stability.
I aim for a 4.5 GHz overclock, but I'm completely unsure about the voltage adjustments and whether I'm setting it correctly. This is why I'm here to double-check my approach.
My setup includes an Asus RealBench, a 15-minute stress test with up to 4 GB RAM. During the test, my CPU reached 83°C but hasn't exceeded that yet. Idle temperatures are between 40-47°C.
CPU details: i7 5930k, overclocked to 4.4 GHz, current CPU Core Voltage is 1.35.
Specs:
i7 5930k
EVGA 1080 TI FTW3Asus Rampage V Extreme Mobo
NZXT Kraken X62 AIO
PSU: EVGA Supernova 1000 P2
RAM: G.Skill Trident Z RGB 32 GB @ 3200
Attachments include photos of my current setup.
Is there any chance the motherboard has an offset? You might try a +0.1 offset instead of manually setting it to 1.35. But if it remains stable, that’s what matters most. It wasn’t stable at 1.3, so 1.35 is the right next step.
If you can stay stable without issues, apply your multiplier for the OC.
BCLK * Multiplier = clock.
Adjusting BCLK is fine and safe, but it also affects other parameters automatically now—so changes like RAM speed can occur if you alter it.
It seems to be around 4.48, closer to 4.5. Going to 100x46 would bring it to 4.6.
102x45 is very close.
105x44 is also quite close.

If you stay consistent and stable, apply your multiplier for the overclock.

You mention it’s at 4.4, but I think it’s closer to 4.48, around 4.5.
Going to 100x46 will bring it to 4.6.
102x45 is very close.
105x44 is also quite close.
100x46 is the cleanest option, offering an overclock that keeps most of the system stable.
Does the motherboard have an offset by chance? You might try an offset of +0.1 instead of manually setting 1.35. But if it remains stable, that’s what matters most. It wasn’t stable at 1.3, so 1.35 is the right next step.
Assuming you stay stable without issues, apply your multiplier for the OC.
BCLK * Multiplier = clock.
Adjusting BCLK is fine and completely safe, though it does affect other parameters automatically now—this explains why things like RAM speed change when you tweak BCLK.
You mention it’s at 4.4, but I think it’s closer to 4.48, nearer 4.5.
Going to 100x46 would bring it to 4.6.
102x45 is very close.
105x44 is also quite close.
100x46 is the cleanest option, offering a good overclock that keeps most of the system running smoothly.
So, are you confident with your current setup? Didn’t I make a mistake during my first CPU overclocking attempt?
If that’s what you’re hearing, well, I’m really happy xD
Also, I just adjusted the voltage once more to 1.32, and so far it’s stable. On this setting, I’m only reaching 78°C instead of 83°C.
You really can't mess it up—it won't allow you.
Yeah, it's okay.
Your BCLK is being adjusted around the whole rig by about 2%.
100 is the stock setting, 102 is an OC of 2%, so everything is effectively adjusted by 2%.
The Multiplier only impacts the CPU and the CPU itself.
Some might argue, "set your BCLK to 100 and use the multiplier, that's what it's for," and I'd understand that point.
But I also think it's okay to take a little risk, and a system-wide OC of 2% shouldn't cause any issues. Their reasoning is that certain components aren't meant for overclocking at all. I share that view, but still believe in taking a bit of a chance.
You can't really mess it up, it won't let you.
Yeah, it's fine.
Your BCLK is OCing most components in the rig by about 2%.
100 is stock, 102 is an OC of 2%, so everything is adjusted by 2%.
That means all parts are overclocked by 2%.
The Multiplier only impacts the CPU and itself.
Some might think, "set BCLK to 100 and use the multiplier," but that's what they suggest.
I also think it's okay to live a bit, since their reasoning is that some parts aren't meant for overclocking.
But I still believe in a little extra.
My main question is how to determine the exact overclock level beyond what I set in BIOS?
Because when I right-click "This PC" and check properties, it still shows my CPU at 3.50 GHz.
I prefer Speccy since it matches my system's parts best.
CPU-Z is also a solid choice.
I like Speccy since it works best with my system's parts. CPU-Z is also a good choice. Does this suggest it's overclocked? Not really.
It's true! X44 and 102 align with what the BIOS states, not the packaging info.
The stats list shows "Stock Bus Speed" as 100, while "Bus Speed" reads 102.
In the chart it repeats again, using a factor of 44, matching the setting in the BIOS.
You're currently at 4.488, which is very near 4.5, making for a solid overclock.
It's correct! x44 and 102 align with what the BIOS states, not the packaging info. In the stats, "Stock Bus Speed" reads 100, while "Bus Speed" is 102. The chart also reflects this, using a multiplier of 44, matching our BIOS settings. You're currently at 4.488, which is very near 4.5—great performance! Thanks a lot!
