[SOLVED] - I needed to re-seat my memory modules. Thanks anyways
I have 725wt Senty power supply. It's not the greatest with only a "more then 75% efficiency rating'.
I also have a Power Color Red Devil RX 480 8gb. The card has two bios. One Bios has the standard reference 480 clock and max power draw of 110 watts I guess at stock. The second Bios has the factory overclock of 1330mhz and 150 watt max power draw. This card has a physical switch on it to choose which Bios I want to use.
I have been using the factory overclocked Bios with the 150wt power draw. I use the card at factory settings. Initially, i thought maybe my cpu overclock had become unstable do to degradation so i dropped my OC to factory defaults and I still had the same issue.
Later I was trying really hard to figure out Wattman's confusing fan curve settings. It turned out I was configuring the fan completely wrong. To keep things to the point, i'll just tell you that I had the cards power limit set at 5%+ assuming it was part of the fan curve settings.
I started getting these weird crashes, like colorful static on the monitor and random hard resets. When this happened I always looked at my boards debug code display and the computer acted like nothing was wrong when the video card dropped out. Eventually it would reset when it figured out the video card was no longer responsive. Other times I had to hard reset the computer manually.
I thought it may of been the driver because I recently updated it. I rolled it back, it didn't fix the problem. So then I thought, well maybe the riser cable its sitting on is causing the problem so I pulled out the riser cable and resat the card in the actual slot. Didn't fix the problem. Then i read some where that an unstable power supply can cause this so I thought well maybe its not getting enough power or its not gettings a smooth flow of power. I switched the bios to use the regular non overclocked bios that draws only 110 watts and at the same time in my research of this, I corrected my Wattman fan curve and dropped the 5%+ power limit to default.
Using the regular bios that uses less power and getting rid of the booster power limit fixed the problem. I quit crashing. So my question is...
Was this because of my shotty power supply? Its a year old. It has a 48amp single 12v rail. Or was this because of the power limit being boosted to its tiny 5%+ maximum? I heard this cards VRM's are kinda junky. Or was this because my OC bios has gone bad? I just want to know if I should flash the factory overclocked bios with a new copy of the same or should I get a better power supply? If i buy another PSU, I am going to spend a lot of money on a really nice one but if i don't have to... I wont. Sorry so long
If it matters, i am using a GA-990FX-GAMING board.
