GTX 570 Unstable Factory OC

post #1 of 5
Thread Starter 
Had my MSI GTX 570 OC for a couple months now and just started experiencing some bad artifacting on the factory OC speeds.
Playing around in Afterburner I can comfortable sit at the default 732/1900 @ .975V without any problems. However if I want to maintain the factory OC (somewhat) of 786/2000, I need to bump up the Vcore to 1.012V.

Just curious is this is abnormal and worthy of an RMA?

I would RMA it..

If you one day decide to sell your graphic card how you gonna do it if it's unstable @ STOCK?

CHEERS..

That was my first impression.

However I am aware that some cards shipped with factory overclocks are undervolted. Just not sure if it's worthy of an RMA if it all that is required is a voltage tweak.

Tried 1.012mV for Factory OC 786/2100, however still unstable.
Wondering if anyone had some input?

My gtx 480 is heavily overclocked out of the box, My first one was unstable @ stock with artifracts in games etc and with a bump in voltage it was still unstable. I sent the card back for a new one and now all is ok.

I would send it back, you should not have to play with voltages for it to be stable. I would also be carefull playing with gtx 570 voltages as there are known issues with blown cards from voltage increasements. Check out the "have you killed a 570" thread

It's the memory overclock. I have the same card. Look at the memory clock of 2100: do you see any other cards that high out of the box? I didn't see any. Mine seemed fine for a bit until after an hour in Bad Company 2... started getting artifacts. Have it running at 2060 now and seems fine.

As for the core: currently running over 850 at stock volts (I found more voltage actually reduced my OC... maybe too much heat, or maybe OCP kicking in... either way, can't complain at those clocks)

So, before you return it, see if it runs fine at a slightly reduced memory clock. If you return it for another model, the memory will most likely be clocked at 1800 out of the box.
