7850 Voltage Crash
7850 Voltage Crash
Hey guys,
I just got my 7850 for my gaming rig. I’m playing at 720p and upgrading from a 7770. The issue is I wanted to run games at higher settings, so I upgraded the card. But the 7850 isn’t powerful enough to fully unlock games like Shadow of Mordor. So I decided to overclock it, just like with the 7770.
Whenever I adjust the voltage on my 7850, it crashes the computer and shows me a blue screen with confusing messages about memory dump or something. The default voltage is set at 1138 in MSi Afterburner. Even small changes cause the whole PC to crash. I can’t even tweak the core or memory clock with the stock voltage because it’s so low.
Anyone got any ideas? Oh yeah, I also unlocked the voltage control.
Shamar Holtz shared his experience using Trixx, achieving 1.25v and tuning settings to 1080mhz and 1360mhz. He noticed artifacts despite the game running smoothly, usually under 70c. He tried adjusting core clock, memory, and voltage but couldn't eliminate them. He suggested lowering clocks further or testing different games to see if the issue persists. He also mentioned that memory at 1300mhz caused artifacts and reducing it to 1250mhz resolved the problem. He recommended checking for program-specific issues and ensuring drivers are updated.
On my 7850 voltage it functioned properly. I tried Sapphire Trixx, and it seemed to work better with mine, being a bit more stable. On the original voltage I achieved around 1050mhz, which is typical. At 1.25v I got 1135mhz, which is lower than usual. Even if I increase the voltage on the 7850, most users reach about 1200mhz, just 150mhz above my stock overclock. Consider trying Sapphire Trixx and share your experience here.

Anonymouselite5 shared their experience with Trixx, achieving 1.25v performance while managing 1080mhz and 1360mhz settings. They noticed artifacts despite good gameplay. They suggest lowering clock speeds further and testing different environments. They also mention that memory issues at 1300mhz caused artifacts, which resolved when lowered to 1250mhz. They recommend checking for program-specific faults and ensuring drivers are updated.
I adjusted the voltage from 1.25v to 1.20v, reduced the Core clock from 1100mhz to 1050mhz, and lowered the Mem CLock from 1400mhz to 1250mhz. The previous settings led to crashes after about 30 minutes with flashing diamond-shaped colors. At the lower settings, no artifacts appeared and performance remained stable. I didn’t notice any issues, so it seems the problem was fixed.
I also played Crysis 3 on High settings with the GPU at 1100 Core and 1400mhz mem for 30 minutes without seeing any artifacts. The game that caused card artifacts was Dying Light; I suspect it only occurs in that title and I’ll check for a patch.
Shamar Holtz :
Okay!
I turned down the voltage from 1.25v to 1.20v, I turned down the Core clock from 1100mhz to 1050mhz and lowered the Mem CLock from 1400mhz to 1250mhz. At the previous settings which would cause artifacts my game would crash after about 30 minutes and would show flashing diamond shaped colors within that time period. At the lowed settings I didn't see any artifacts and I also didn't notice any performance changes (Which I thought was very odd, but i ain't complaining) So I guess that's fixed
So I played Crysis 3 on High settings with the GPu at 1100 Core and 1400mhz mem for 30 minutes and didn't notice ANY artifacts at all...
The game that was giving the card artifacts was Dying Light, Since I didn't see it on any other games I guess it only happens on Dying Light. I'll look for a patch or something
hmmmm. If there's no performance difference there's no point. Was 1050mhz the furthest you could get with 1.2v? Your card doesn't seem very overclocking friendly
🙁
The average 7850 gets 1050mhz on stock voltage.
Try keeping your card at 1.2v and if you haven't already push your memory and core clock up in small steps until you notice artefacting or crashes.
I agree with Razier, that voltage is not worth the extra mhz you gained.
-good luck
Shamar Holtz shared his experience adjusting settings to resolve issues. He reduced the voltage to 1.20v, lowered the Core clock from 1100mhz to 1050mhz, and decreased the Mem CLock from 1400mhz to 1250mhz. Previously, these changes led to crashes after about 30 minutes and flashing diamond-shaped colors. With the new settings, he didn’t observe any artifacts and reported no performance drops. He tested Crysis 3 at high settings with a GPU core at 1100MHz and a Mem clock of 1400mhz for 30 minutes without issues.
He also mentioned that Dying Light was the game causing artifacts, possibly due to memory clock issues. He noticed artifacts when his memory exceeded 1280MHz (sometimes up to 1280MHz or 1280MHz with 1400MHz). Since he didn’t have a heatsink on his memory, heat might be a factor, but he wasn’t sure.
On another note, he runs games at 1080p with a core set to 1000MHz and a mem at 1260MHz, achieving around 50fps in Dying Light. He observed that Dying Light performed poorly on AMD hardware, suggesting he might adjust Crossfire settings or find a suitable GPU speed. He also noted that after beating Dying Light, he preferred games not developed with manufacturer-specific software/engines for better performance.
He also pointed out that this discussion is from 2015 and if the card is still in use, it could be helpful. If not, his memory-related concerns might be useful.
