![]() By default, Afterburner locks out voltage adjustments. It shows sliders for core voltage, power limit, core clock, memory clock, and fan speed. Here's the main interface for MSI Afterburner, using the v3 skin. Case in point: Even though all the RTX 4090 cards we've seen so far appear to use Micron 21Gbps GDDR6X memory ("D8BZC" labeled chips), we've seen maximum stable memory overclocks range from 22.6Gbps to as high as 25Gbps. ![]() Please note that overclocking very much depends on the "silicon lottery." Just because one person with a "HappyGPUs RTX 4090 X-Factor-Wow" model card (that's a made up name, if you couldn't tell) managed a 20% core overclock and a 25% memory overclock doesn't mean that every RTX 4090 card will hit those same clocks, or even that the same model will reach similar clocks. It's also possible to overclock AMD and Nvidia GPUs using the built-in utility in AMD's drivers or Nvidia's GeForce Experience, which we'll cover below, but we'll start with the universal approach to overclocking your GPU. The same basic process can be used with other utilities, including EVGA Precision X1, Asus GPU Tweak, and other graphics card vendor utilities. There are a variety of utilities, but we're going to focus on MSI Afterburner, which is one of the most popular and commonly used GPU overclocking tools. Once you have your baseline stock performance data, it's time to start overclocking. Check our guide on how to test graphics card performance, and you'll also want to check your graphics card temperatures and clock speeds. You want to be able to see how much faster your PC runs after tuning, after all - if performance doesn't improve, you'll want to know. But if you have one of the best graphics cards and you're looking to eke out a bit more performance, we'll discuss how we go about overclocking and determining "safe" settings.īefore overclocking, it's useful to get a baseline measurement of how your graphics card performs. Of course, as with any overclocking, care should be taken to avoid running your GPU at unsafe settings. It’s definitely weird, it feels like they bundled D4 npc’s with an integrated gpu burn test, or maybe vendor npc’s are as well crypto-miners hijacking our gpu’s Nothing fishy i guess ofc, but this looks completely abnormal.Overclocking your graphics card can improve its performance by 5% to as much as 15% (or more), depending on the particular card model. When i’m in the vendor/blacksmith menu, these are bumping quickly (and stays stable at the following values in my case) :Īnd i can even hear the fans starting to work harder. to avoid hammering it too much and keeping temps at bay with D4, i’m capping fps to 100 (gsync on), and using balanced DLSS, all that in 1080p, + i’m using an MSI afterburner curve for a slight undervolt. when i use my performance overlay to check power draw / frequencies / temps.Ĭurrently i’m using a Lenovo laptop with a mobile 3060. I noticed as well a strange behaviour with city npc’s, being the weapon vendor or blacksmith. As this is more likely to kill gpus than a vram leak. At least with some lines.ġ.1.1 is addressing the vram end of the issue but I’d like to get a handle on how many other gpu lines are fluctuating on specific npcs. It’s less D4 exposing average cards and more D4 exposing cards that aren’t heavily overkill. I will say that if these cards had overkill pcb components and a solid asic rating, they may have held out. In the cases of the cards I’ve dealt with the issues have been majority failed inductors, with one resistor, and 2 unknown memory related issues. Constantly switching between low and max load is extremely hard on power phasing and can cause things to fail that 3dmark or a stress test will not. For example while sitting at the blacksmith in Zarbinzet, the 3070ti I’m testing on now will constantly jump between 50% and 97% usage with vram maxed as well (for some reason the 7900xtx uses 22gb of vram as well but does not fluctuate). Specific npcs cause a nonstop load fluctuation. You can replicate this, but do so at your own risk. I build computers often so I had a decent amount of test control.ĭiablo 4 is a creating a scenario that is tougher than a 100% load on some GPUs, I’ve confirmed 6k/3k series and suspect the same goes for some others. The 6k amd and 3k nvidia gen cards seem to be specifically vulnerable to this issue. That was until the 8th gpu I worked on that was stated to have “fried from D4” (I’m at 9 now). In the past has this has always been a case of the game exposing a weak part on the pcb, inductor, resistor, chiplet etc. As someone who’s been repairing gpus for over a decade now and works at a repair shop, I’m typically the first one to speak up when people claim “x game fried my gpu”.
