Jan 22, 58 9 65 Hi all, So I've been into PC building and gaming for quite some time now since aboutso I feel pretty confident with my computer hardware skills.

One avenue that I have more recently been exploring is GPU overclocking. I've definitely gotten the hang of general overclocking and stability testing except for manipulating the voltages on GPUs using Afterburner. Now, I've done my research and tried different things to unlock voltage control, but none of them seem to work.

I've of course tried the check boxes in the settings for "voltage control" and "voltage monitoring" to no avail.

I've also tried editing the. I've tried modifying the. Lastly, I've also tried the beta version of Afterburner too, again, nothing. When I say that open hardware voltage range fixes "dont work," I mean that at a hardware level.

The open hardware voltage range listed above do actually unlock the voltage slider in MSI Afterburner, and I am able to change the voltage that supposedly goes to the GPU, but there is no actual change when I apply it. I know that there are modified vBIOS options out there that could solve the problem, but as far as I'm aware, others have been able to unlock voltage control without modifying their cards.

Is modifying the core voltage even possible on most GPUs, or are most locked by Nvidia? Seems kind of pointless to have voltage control options on a tuning utility if most GPUs would be incapable of utilizing them. Thanks in advance if you made it this far, and let me know if you have any ideas.

RememberThe5th Splendid. Jul 30, 6, 25, 1, Well lets say, I have my R9 and I open hardware voltage range change the core voltage unless I flash the bios of it. No matter what. Some GPUs have to be flashed to be unlocked.

As for mobile GPU's I really open hardware voltage range not know if they "Even" can be overvolted, but as I know for mobile open hardware voltage range better to use lower voltage for higher frequency lower TDP on higher clock speed, ex.

I've managed to hit and unofficially beat Unigine Benchmark 1st place. And the old GTX I needed to use other tool to boost core voltage a bit, not sure the name of it tho.

Also fun fact, GPUZ on sensor tab says what is your limiting factor at perfcap. Indicating performance is limited by voltage reliability. Indicating performance is limited open hardware voltage range max operating voltage Hardware Limit. Indicating performance is limited by total power limit.

Indicating performance is limited by temperature limit. Indicating performance is limited by GPU utilization. Reactions: SparkyTech Thank you for the extremely detailed response, I appreciate your time. I'm always trying to learn more, so this is helpful. I can't say I understand it completely, but I'll get there. So anyways, you kind of confirmed what I was thinking as far as some cards needing to have their vBIOS flashed in order to be Open Hardware Bench 900 unlocked.

I also believe you are right in assuming that most mobile GPUs aren't unlocked probably due to their strict power usage specificationsthe only reason I brought up mobile GPUs is because I wanted to test this over multiple platforms. So based off of the information that you supplied, I will definitely be downloading GPU-Z again I've used it in the past, but have since switched to using HWiNFO as my "one stop" and exploring the perfcap sensor values.

Based on your overclocking experience then, is it very uncommon to be able to actually to modify a GPU's core voltage using the slider on Afterburner with the open hardware voltage range vBIOS? Is it instead realistic to only be able to squeeze as much performance out of a GPU as allowed by the stock voltage?

Thanks again for your detailed response, and we'll see if anyone else has any thoughts on the matter. Sorry Im kinda "Ingrish man". Not my main language. As far as I experienced Overclocking on my hands. My first bought GPU R7did not have any vcore adjustmentsbut with bios modding I've pumped from open hardware voltage range. This was the first GPU I dared to modify bios, I failed couple of times, but its Way easier to re flash the stock bios onto it than lets say laptop if open hardware voltage range into open hardware voltage range bios.

When you try yourself this Custom Core Curve, you will get it. Also failed to mention, Overclocking only with memory and core clock will not damage GPU in any open hardware voltage range, unless you overvolt your GPU core, only drivers "May" get bugged. Sounds good.

Thanks again for the input. Oct 17, 1 0 10 0. Hey, i was wondering if anyone else has had this problem. Ive been using afterburner fine for years now, until recently yesterday i had full control of my core voltage control. I've also had a windows update too before noticing the core voltage break. I've currently tried uninstalling all nvidia software and reinstalling older drivers, flashing open hardware voltage range new bios, reinstalling afterburner with all conventional.

Any help would be really appreciated. Islam Ghunym Prominent. Feb 20, 7 0 0. ForestFireX said:. Last edited: Jan 14, You must log open hardware voltage range or register to reply here. Post thread.
