Gpu voltage how much

Any suggestions? I may be late to the show, but spikebyte If the Dell G3 is a laptop, you cannot overclock voltage due to power constraints on Laptop Power Voltage. Older models will be similar, but not the same. AMD Radeon users, click here. Setting up MSI Afterburner 1. Click the Settings gear. MSI Afterburner Overview 1. Afterburner info click me All fields are top top bottom, left to right. This is a raw count of the number of frame stutters and dips experienced in the benchmark.

This guide will aim to lower this percentage. Benchmark results The chart below details various overclocking profiles with results from the Forza Horizon 4 benchmark. At any rate I appreciate the guide. Have you actually gamed on it? Synthetic benchmarks only show so much. For the initial overclocking, you can also set a static fan speed with a noise level you find acceptable, like 80 percent. That should keep your GPU as frosty as practically possible, and you can tune the fan speeds later.

Starting by overclocking your graphics card's memory is usually pretty straightforward. Run a looping benchmark in the background—Unigine's Heaven in windowed mode is perfect for this—and boost memory speeds gradually using Afterburner's DDR controls until small artifacts such as stray pixels or other glitches begin appearing.

We recommend going up in 25MHz increments, as memory tends to fail gracefully and you'll usually get plenty of warning signs before crashes or lock-ups happen. Don't forget to hit 'Apply' after each speed change. After finding the peak memory speed, adjust the memory clock down slightly usually MHz until no anomalies occur, then reboot and let the benchmark loop for around minutes using these settings.

Due to the variable nature of clocks on the newer Nvidia architectures, it can take a while or a mixed workload for instabilities to appear.

If no further problems pop up, record the setting, and then ease back from the edge slightly another MHz to provide a margin of stability. Keep in mind that your stable point may go down further when combined with the core overclock we're going to do next. If you want to be extra thorough, now is a good time to benchmark the card.

Check performance in the same tests you used before and record the new results. Now it's time to overclock the GPU core. Using stock memory clock settings we'll reapply the changes you made in the last step at the end , start gradually increasing the core clock in small, MHz increments, with a looping benchmark in the background to monitor progress.

Keep a lookout for stuttering, screen flashing, or other problems, as core instability is far less forgiving than glitchy memory.

If you do experience a crash, your maximum safe overclock will be at a lower setting. Don't worry if your system locks up, a driver error occurs, or some other issue rears its head. Just reboot, use a slower clock speed, and soldier on until you find the card's maximum stable core frequency. Test with a minute benchmark cycle and record this overclock value. As with memory, dial it back just slightly and leave a MHz safety margin. As an alternative, EVGA's latest Precision X1 utility supports a "scanner" mode that will attempt to find a stable overclock, using a non-graphics workload so that it can gracefully crash and recover.

It tends to err on the side of caution, which isn't a bad idea. It takes about 20 minutes to run and eliminates a lot of the guesswork, though we still typically get better results with manually overclocking. This is another good time to consider a few quick benchmarks.

This will tell you how much performance improves with higher GPU core clocks. Now that we're armed with both the maximum values for the memory and core speeds, we can combine them and see how far we get.

Since Nvidia's design is essentially power limited in its current state, don't be surprised if you see instability with all the clocks turned up to the maximum values found earlier. If there isn't enough power to go around, you'll need to balance the memory and core clocks for the best performance mix. This is where the two sets of performance results gathered at the end of each of the above sections become useful.

Some GPUs are limited primarily by memory bandwidth, others just want more core clockspeed. If you saw bigger gains from the GPU core than memory overclocking, prioritize the core speed first and step back on your memory overclock. Get it for Android , Mac. Get it for Mac , Android. More on that later. MSI Afterburning overclocking utility.

However, EVGA requires you to sign up for an account before you can download the otherwise free and great tool. However, in my experience, an overclock shows its true effects after a few hours of real gaming.

I personally use two tools for that: 3DMark and Unigine Valley. Run this test and get a baseline of the framerate, stability, clock speeds and temperatures of your GPU. Before you start with step 1, make sure that you benchmark your default performance see section above to determine the baseline performance.

MSI Afterburner overclocking settings. The current voltage — Note that most modern GPUs prevent you from changing the voltage, as it could harm the hardware. Beyond that, things might get too hot and the graphics card could throttle itself. If your card has a limit of watts, you can increase it to watts by moving the slider to the right.

Watch the temperatures and noise level, though. The higher the limit, the hotter things get. Temp Limit — This increases the temperature limit before the GPU starts to throttle things down too much. Core Clock — Magic button number 1! This increases your GPU clock and is one of the key measures to improve performance.

Memory clock — Magic button number 2! This one increases the frequency of its memory, which increases bandwidth — another key factor to get more FPS. Startup — This button enables you to launch Afterburner every time your PC boots. This will give you some headroom for the first big step of overclocking. Hit the OK button 9. MSI Afterburner step by step overclocking.

Is everything running ok? Run 3DMark and Unigine Valley.
