Voltage problems - UPS/AVR

Hey, so I've gotten several GPU's in the past and I had a similar problem on all of them, also on my hd 4600 iGPU. Basically, at a certain point after using it the graphics go bonkers (from 1 day to 2 weeks of usage). Aliasing is horrible, jagged lines everywhere, AF not working, broken shadows (look very low quality). I recently RMA'd my gtx 960 due to this issue (still waiting for a new one, hopefully) but I've received some information from a guy who claims that this issue is a voltage issue, saying that buying a regulator fixed it.

I live in a house where electricity is really low quality and I was wondering, is it likely for this to be a voltage issue?

I'd invest in a regulator, but it'll cost me 50 and I was wondering if that is a worthwhile investment.

I was looking at this one:

BlueWalker voltage regulator: AVR 1000

A 600 watt regulator (should be enough, right? My system has a 650 power supply but uses 384 on 100% load).

Would this help in stabilising the voltages?

Another question; Would I need a UPS to properly regulate voltages or would an AVR be enough? UPS with sufficient wattages will cost me over 200 in my country and that's not really what I want to spend right now.
 
If it was the voltage coming into your PC then it should be affecting other components and not just the GPU. Sounds possible that you may be having issues with your PSU, what's the make and model of your current PSU? Also how old is it?
 
It is actually all components I believe. My iGPU in my 4670 has the same issues also supposedly due to the voltage.

My PSU is a new one, G650M. Had the same on an old one.
 
If your input power was too dirty for your PSU to clean it up, you would see issues like random shutdowns or hangs. If it damaged your GPU in any way, you would see issues like games crashing, pixels or regions of the screen stuck certain colors, or just total graphical corruption.

Since you're seeing specific rendering issues and not just general corruption as described above, your problems seem like they're probably driver-related. Try a clean uninstall and re-install of the latest Nvidia drivers. Also, if you're using Virtu or anything like that, stop and plug the monitor straight into the GPU.

Hey, I and a group of other people have been plagued with this problem for what feels like an eternity. We have tried everything, from all the possible modded drivers to buying new components and entirely new PC's yet this problem remains. What could it possibly be? I am really clueless and considering we all have it it really has to be a power issue =/

Total graphical corruption sounds like a good way to put our issue though. AA not working or looking horrible, AF not working, jagged lines in everything from games to simple windows text, lots of popins, draw distance reduced in all games, some artifacts here and there and the IMO worst: z-fighting in all games. Not fun to try and play a game when everything around you flickers like mad. This issue killed all gaming for me.

Again, all of those things are occurring deep within the rendering pipeline becasue they are affecting recognizable parts of the game. Physical GPU or memory issues would be totally independent of in-game geometry. You wouldn't see issues at the level of polygons' Z-fighting, you would see green or purple graphical artifacts all over your screen.

I would do a fresh install of Windows and the latest Nvidia driver.
 
Not joking when I said I tried everything. People with the same issues also notice this on other devices such as their Playstations and Xboxes. Also, EVGA sent me a replacement card back but they said there was nothing wrong with the card itself. It can't be another component because some of us bought whole new systems yet this issue persists. Power seems like the only logical conclusions.

Anyway, I ordered some cheap 40 euro AVR I found which should do a reasonable job. I really hope you're wrong because otherwise I'm going to be sad :S
 
I got a new GPU from EVGA and gpu voltage is very stable. I have noticed however that my vcore is fluctuating like crazy.

I tried running a stress test and vcore is fluctuating from 0.3 to 1,04 about every 100 ms. That can't be good can it?

Nobody wants to spend the $$ on this stuff. However, I would recommend a quality UPS with AVR to most anyone and in your case it sounds like a necessity. You should not cheap your way out. You want stability in your power delivery than you need a UPS w/AVR. If it's not your power than it's your power delivery - your power supply and/or motherboard. You need a quality UPS w/AVR anyways so I'd start with that.
 
Come to think of it, I don't think I have ever monitored cpu or gpu voltages at a 1/10 of a second interval.
 
Hmm I played around with bios settings, got stable voltages now but no difference.

I ordered an AVR anyway just as an act of yolo but haven't heard anything back yet from the company ._. forunately I paid through paypal..

Anyway, I am still confused as to what this issue is. You can see what I'm talking about here

So many people are suffering from it right now. Look at the comments section. We tried literally almost anything.

Buying a new gtx 960 got rid of this issue for about 1.5 weeks after which it started again. I got a different gpu from evga through rma but still the same issue persists. Each time you think "this migth be the problem" but then something else pops up which contradicts it and then you just don't know anymore what's causing it.

Could it be the PSU? I replaced it already, no difference.

Could it be the motherboard? Not possible. Same mobo my r9 290 had this issue on my gtx 960 worked fine (that is, for 1,5 week after which it broke again).

Could it be the GPU? We've tried tons of 'em and it still happens even on brand new ones.

Could it be the HDD? What in an HDD could ever cause this?

Could it be the ram? Same story as HDD

Could it be windows? I've tried different windows 7 and windows 8, no difference.

Could it be new drivers? No because I didn't have this issue for the first 1.5 week. If it were the drivers it would've never worked in the first place.

Could it be the brand? Both AMD and NVidia.

Then you have that guy that pops up saying he got this issue with a brand new build. At that point any clues you had are just gone. It is insanity, it is so inconsistent.

I have no fucking clue and I'm just sad. I'll make sure that whoever comes with a solution will get a world peace nobel price

This is not making too much sense to me.

The power supply and the motherboard and the graphics card all have circuitry to provide clean and stable power to the components.

The mains AC supply should have little effect on a computer as long as it's not completely out of bounds.

vCore will not stay steady, it fluctuates to save power, that's totally normal.

What you've shown in your video are rendering artifacts that have really nothing to do with input power. Seriously, try different driver versions.

third time, I've tried anything, that involves every single driver that's even out there for this card.
 
If your full load power is 384 watts then you're going to want a 800 watt regulator. Also, you should probably plug your display into the same regulated supply so that means even more power it must supply.
 
THe best way to help diagnose this would then go buy a battery backup UPS.
Do not buy the sissy ones because they will not help you with your house electricity problems. Buy the $400 models. But if you are made of money then go out and do buy those home entertainment regulators that will clean your voltage. If you want to be super serious then buy 2 regulators and chain them together Then plug your battery backup into that then plug your pc into the battery backup device.

Old buildings will have issues like you are having. You may even want to investigate into buying one of those TESLA batteries for the home. I'll buy the tesla batteries once I paid off my car.

He'd have better luck going down to the power company and shaking his fist at them...

Both will probably have equal effect on his graphics problems. :biggrin:
 
Welp the AVR did nothing. There goes my last shred of hope. I don't know what this problem is but it is driving me insane. What could it possibly be? How can this be a problem that lasts even after replacing a whole system? Why did it suddenly start happening? Why is nvidia blatantly ignoring it when there are so many more that suffers? Why does amd have the same issue aswell. It is driving me insane. If I ask any company for help they'll tell me to reboot my pc and try to install fresh drivers. It's all bullsht advice for computer illiterate people and it does nothing to solve this issue. This is way deeper than that.
