how safe is my Modded GPU BIOS OC ?
Hi guys, I have a GTX 980 Gigabyte G1 gaming card with stock cooling. My OC clocks are 1507Mhz, 3.7Ghz, and 1.250V. The BIOS wasn’t modified myself—it was done by an expert who worked on BIOS for 900 series cards. I’m asking for a fair assessment of the risk factors from this modded BIOS, without any bias. I played Crysis 3, FarCry 4, and ran Unigene Heaven and Valley Benchmarks on ultra high settings.
I don't see any distinction beyond clock speed, memory speed, and temperature. You were okay with the custom VBIOS. It's up to you whether you want to take the risks.
The PCIE 16 @ 1.1 is designed to improve power efficiency. To check the real link speed, click the "?" next to it and begin the render test. For the person asking: I have a Gigabyte 980 Ti G1 gaming card and have experimented with a VBIOS from the same developer. As long as you don’t encounter BSODs, TDR issues, or system freezes, everything should work fine. If problems arise later, first check if a new Nvidia driver is causing instability—new drivers might help. If none were recently installed, consider reducing core and VRAM clock speeds by 100MHz to see if stability improves. If that doesn’t work, you may need to increase the voltage or accept a lower overclock value.
John Wittenberg explains that the PCIE 16 @ 1.1 setting helps save power. To check the actual speed, click the "?" next to it and begin the render test. The person who replied mentions they use a Gigabyte 980 Ti G1 gaming card and tried a VBIOS from the same developer. They suggest checking for BSODs, TDR, or freezing issues before proceeding. If no new drivers are installed recently, lowering core and VRAM clock speeds by 100MHz might restore stability. If that doesn’t work, increasing voltage slightly could help, or accepting a lower OC value may be necessary. John shares his own experience with modded BIOS settings for two weeks, noting a BSOD once due to an unupdated SSD firmware. He found a forum post about an EVGA 980 with similar settings and a failing GPU after turning it on without reason. He wonders if this could happen to him since he doesn’t have a water cooling kit or high OC settings.
GPU's are similar to other devices—they can malfunction unexpectedly due to manufacturing issues, heat, or faulty fans. With EVGA, you receive a minimum 3-year warranty, provided they haven't discovered any modifications to the VBIOS, which would cancel the warranty if not re-flash during RMA processing.
GPU's are similar to any other equipment - they can malfunction at any time due to manufacturing issues, heat, or faulty fans. With EVGA you receive a 3 year warranty at least, provided they don’t discover you changed the VBIOS (which would cancel the warranty if not re-flashed during RMA). Thanks, but I still re-flashed my stock GPU BIOS and the screenshots show that the modded version performs better in terms of frame rates and overall quality. However, I’m worried about the risks involved. Could you compare both screenshots and the one from your friend with the original? Please let me know if there are significant differences in performance or factors affecting the GPU’s health. Sorry, I’m a complete newbie.
