This model does not allow adjusting the voltage settings.
Hello everyone
My current specs are: CPU Intel® Core™ i5-3570K 4.1GHz, Motherboard Asus P8Z77-V, Memory G. Skill 2X4GB DDR3 1333, PSU Corsair TX650, GPU Asus HD7850 2GB (HD7850-DC2-2GD5-V2) X2.
I'm applying this overclock for both cards with a clock speed of 1025MHz, memory at 1350MHz, and a voltage of 1.210mV.
My issue is that both cards, despite being the same model, have the stock voltage at 1.210mV.
I believe I could run the OC at a lower voltage to reduce heat, but I can't adjust it.
I've used Asus GPU Tweak with Overclocking Range Enhancement, MSI Afterburner (no voltage adjustment option), and Sapphire TriXX.
It still doesn't work—I've tried changing voltage in both tools, but the result remains unchanged.
The voltages are consistently at 1.210mV even after attempts.
Is there something I'm missing? Any advice or information would be greatly appreciated! Thank you in advance.
Hey there, I was just thinking about it. Have you found a way to solve this? I’m facing the same problem with the same card—voltage stays locked no matter which overclocking software I use. The fans are good for overclocking, but without being able to adjust the voltage, it’s really frustrating. I’m curious if these cards are faulty or if there’s something else going on. I’ve seen others get great results without voltage issues, but I need to understand what’s happening with mine.
Hey man, I was just checking if anyone else found a way to solve this. I have the same card and am facing the exact same problem—voltage stays locked no matter which overclocking software I use. The fans are great for overclocking, but without being able to adjust the voltage, it’s really frustrating. I’m starting to think our cards might be faulty, since I’ve seen others get amazing results without any voltage issues. I’m currently at 1100/1370, but Far Cry 3 keeps crashing, so I really need to dig deeper into the voltage readings.
Did you ever come across a solution or at least understand what’s going on?
Unfortunately, I haven’t. I reached out to Asus technical support and got this response:
It's frustrating, I'm starting to believe ASUS decided to restrict the voltage on this card recently, as I've noticed this happening with some companies before. It's particularly bothersome because this card costs $220, while similar ones are available for as low as $180. The main reason people buy this card is its excellent heatsink for overclocking, so if they really locked the voltage, it would be a big oversight. I'm considering returning it to get a 7870 instead, since certain promotions let you purchase them for $220 regardless. If I can't get a refund, I'll look for another one and check if it's also restricted. I'll keep you updated, but the whole process should likely take 2-3 weeks.
Newegg took my request for a refund, which means I won’t be able to assist further since I chose a different option. Assuming you’re past the 30-day window with Newegg, you might still get replacements from ASUS and avoid similar problems. Still, I believe you’re lucky to have two 7850s in your collection; reviews suggest this combo should beat standalone cards and last for a long time. Sorry I couldn’t help further.
Gigabyte has begun restricting access recently too
🙁
I came across a review for the identical model prior to buying, but now the updated firmware prevents modifications. It's disappointing they've made this change; I prefer lower voltage and want to confirm stability on my own.
It's doing 30% better with the 10% factory overclock than my upgraded 7850 was, so I'm happy about it. But honestly, I bought it just because I wanted to, but once I chose the 7950 it wasn't too important to overclock since it would be much better than my original card. I plan to let it sit until games catch up. It's currently running Far Cry 3 at max (with postfx off) at 4x AA and 40fps, which means I'll stay in good shape for a while. We'll find out when BF4 is released though, haha.
I'm obviously late but I still have the same card. Instead of using GPU-Z, I checked the Asus GPU Tweak monitor window. Although it might not confirm, adjusting the slider to 1165 makes it seem like a downclock, but it's actually stable. My current settings are 1155 core clock and 5760 Mem Clock (1440 Mem).
