Purple blocks and bars on screen

Hey guys,

Yesterday I was playing GTA Online with a few people and at two times within an hour or 3 I noticed a purple block appearing on the screen and disappearing in the same second.
I figured it was a game bug.

However, this morning I fired up the rig and got purple bars all across the screen for a split second on the Windows lock screen.

Seems like my GPU is on its way out? :s

Thanks in advance!
 
Yikes that sounds like failing memory mate,your card isnt that old though is it 0_o

Yeah, I thought that.
I've not even had the card for a year but I did buy it used.


It sound to me like a corrupt BIOS, probably fatal.

JR

It does run a custom bios, but it's just the stock one with a lower minimum fanspeed. Also I flashed it in like February and the issues started yesterday.
 
Hey dude, try underclocking the ram by 100MHz

If you have the option in afterburner etc give the ram a few more volts too.

Sadly if that doesn't work then you may have some ram on the way out.
 
That sucks dude

Yep :|

One of those days innit.

Alright, I've underclocked it by 100MHz. Will do some GTA tonight and see if it happens again. Thanks

If it's not the ram it's broken solder contacts so if you can it would be RMA time.

Well tbh I had a massive problem with the minimum RPM of the fan so EVGA told me the only thing that would fix it was a VBIOS mod which would also void my warranty.

Unfortunately they lied to me, as I flashed the VBIOS only to find out the fan was locked at 40% minimum on hardware level. I then also decided to paint it cause I had no warranty anyway, so I very much doubt EVGA will take the card back.



On the bright side I'll have the most badass looking brick I've ever owned

Surely you never had a warranty if it's used?

JR

Not sure, I think EVGA has or had this thing where you can pass on the warranty?

Also when I emailed them I did say it was used and they still said flashing the bios would void the warranty. They then proceeded to tell me I should buy their new 970 and 980 cards at launch...
 
Update

Played an hour of GTA with underclocked VRAM (regular voltage) and nothing so far (also did a Heaven run, but that only used 1.2GB of VRAM).

Runs at 2903 MHz now so marginally slower and I didn't really notice a performance impact.

Can it happen that RAM just gradually dies a bit more and more, or is it just gone and that's it? Cause if the latter, my problem might be slightly different.
 
Well memory chips degrade, I remember that during the SSD tests the SSDs started losing performance after some write/erase cycles
 
You could have probably sorted it with a bit of ram volts but the downclock fixing it pretty much confirms what I thought and its just a bit of silicone degradation

Think of the degradation process like a CPU. After a while it gets a little tired and instead of sprinting, it decides to jog. It'll jog for quite some time until it feels exhausted, then it just stops. That's just a simple analogy:)
Though memory is more often susceptible to failure than a CPU. This is because there are more dies of memory than CPU(only one die), meaning the probability of failure is therefore increased. Now obviously you can speed up the process with to much volts or to much Clockspeed because leakage gets worse and worse which will cause them to die quicker. Vram is usually the most common memory failures because they already have high clockspeeds, and GDDR5 uses 1.5v(imagine a CPU running that much 24/7) to run at the 7gbps speed. This is very high volts and has a much higher chance of leakage and that'll speed up the process. Now the cards Nvidia/AMD produce use high quality metals and etc. for their caps to handle high volts and prevent leakage, but eventually they all will give in. Just a matter of time.
