vcore value low
vcore value low
Hi Guys
I'm working on my fx8350 with a Gigabyte gaming SLI card and BIOS version F1. The vcore can't exceed +0.775v, but I think it should be at least double that, around 1.3v to 1.4v. My PSU is a Seasonic Gold 550w, and the GPU is an RX580 with 8gb of VRAM. I'd appreciate your advice on why the vcore isn't increasing further. Thanks.
Non-x is 65 and x is 95W TDP but they match at the same frequencies. "X" is a higher binned processor running faster. In reality, all Ryzen chips begin with nearly identical dies, featuring the top R7 1800x configuration, while others have reduced or removed cores, down to R3 1200.
Have you disabled every power-saving setting? When you mention +0.775v, it seems like a correction rather than a voltage value. Indeed, 1.4v would only be the beginning for OC.
Garry.scanlan shared his findings with CountMike, asking if the voltage adjustment was intended as an offset rather than actual power saving. He clarified that 1.4v would be a starting point for overclocking and mentioned checking the current status page, which showed vcore at 1.476v. He described the process of adjusting the CPU voltage in advanced settings, noting that changing it to 'Normal' and then to '-0.800v' allowed incremental increases up to +0.775v. He also advised verifying voltages through the CPU's monitoring tools rather than the BIOS until the desired value is confirmed.
There should also be a C6 power saving feature to turn off, along with any turbo settings. As soon as you begin overclocking, you manually adjust the voltages. Therefore, are you configuring by multiplier or FSB?
PS. Avoid using offset and manual voltage adjustments at this stage.
CountMike understood the configuration. The settings look good: Cool & quiet / Core C6 / HPC / APM.
On my old board (UD3), I adjusted the multiplier to get 4.2 / 4.4 / 4.6 and then tweaked the vcore as needed.
I also oc'd the chip to 4.6 on a previous gigabyte board.
What’s puzzling me is that although I can change the multiplier, I can’t find any way to adjust the vcore voltage.
Vlad: Got it. Thanks.
As I said before, the vcore value listed on the MIT page shows 1.476v – which matches what I’d expect if I had changed the multiplier.
Should I just keep raising the multiplier until it fails?
No worries, I’m still getting the hang of OC despite reading a lot online.
Which cooler is suitable for your CPU? A quality one can support up to 1.5v or higher and provide excellent overclocking potential. I used an FX 6350 at 1.55v and 4.8 GHz for two to three years without issues, thanks to a large Mugen 3 with 120mm fans that kept temperatures below 60°C. Also, are you enabling AMD Overdrive for monitoring?

CountMike :
What cooler are you using for the CPU? A quality one can support temperatures up to 1.5v or higher and still allow good overclocking. I’ve been running an FX 6350 at 1.55v and 4.8 GHz for several years without any issues, thanks to a Mugen 3 cooler with two 120mm fans that kept temperatures below 60°C.
Btw. Are you enabling AMD Overdrive for monitoring?
I'm using a Cryorig H7. My previous oc on this chip at 4.6ghz was the good old EVO 212.
Since posting I've tinkered a bit with FBS and multiplier and without changing any voltages or turning off any power saving/control modes i'm hitting 4.3ghz and HW monitor shows I'm hitting 4.4ghz max.
But I'm still wondering where in the BIOS I can change the vcore voltage if what I was using is the offset voltage.
Does this board automatically change vcore for me as I change the FSB and multiplier settings?
