GTX970 red dots while using a minor OC in GTAV

post #1 of 8
Thread Starter 
Hi guys,

So I was testing my OC potential of the G1, and everything above +75MHz on the core gives me some red dots for a split second and then appear again after sometimes a few seconds and sometimes after a minute or so.

My question is, should I upgrade the fan curve or it needs more voltage? In Valley/3Dmark there are no artifacts or nothing like that.

Type R!!

What are your temps and voltages set too? My 970 loved voltage, I was able to squeeze quite a bit more out of it, but if you temps are already high, it won't help all that much.

Hey, thanks for a quick reply. My temps are really fine, I can keep them under 65C after tens of minutes under stress testing, they are fine.

Thing is without a BIOS mod I can't get above 1.250V, and currently my OC is running at 1.225V. Maybe mine loves voltage too?

I'd just like to know why does artifacts appear, they only happen after some time gaming. Is it a sign that the card needs more voltage or it's a notice not to go further? I've never had a driver crash or anything. I'm using boost and I get up to 1492MHz core and I see artifacts only in GTA V, but GTA V is maxing out all of my PC resources and provides massive heat, though I have a huge case with 2 radiator exhaust fans, 140mm exhaust fan and 2 120mm intakes. The temps in the system are just fine.

Yeah 65c is good, that is what both of mine ran at under stress. You can always try more voltage, and if you still get artifacts then you know that it wont help. Same thing happened with me, no artifacts in either firestrike or heaven/valley, but Witcher 3 game me issues. Had to run the core a bit lower to run that game without artifacts.

This is where I got the tools to flash my 970 the first time.

Good video showing how to do it. (Bit slow though... but thorough.)

I have asked Mr Dark that mods the BIOSes to make me one and explained the situation, I'm just trying to get that bit extra from it without flashing the new BIOS that will lock my voltage to 1.275V, which seems a bit high right now. I'm trying to go stable with those 100MHz extra on the core. I will try to play with it a bit more and see what comes out. It just annoyes me that it starts happening after some time, I haven't even noticed it while I played some short sessions just to test the stability.

By the way, 1500MHz boost from a 970 is decent? I've seen everyone talking like it's mostly what people with get at max. I just don't know wether they mean 1500 boosted or 1500 + boost.

And I'll also check the video for modding the BIOS myself, thanks for that.

By the way, are artifacts dangerous? If I stay within the safe zone voltage and heat-wise, can they do damage by themselves?

Yeah man I hear ya, I would mess around with it some more, you may be able to get it stable.

1500mhz is fine, I had my 67% ASIC running that, while my 72% could run 1530 stable. I think stock in SLI I could do 1482 with both cards, and with modded BIOS I could do 1518mhz game stable. I would give the BIOS a shot man, I think it helps the card a bit. I know it seems high, and your temps may go up a few but it's worth a shot.

And no they are not dangerous, it's just merely showing you the chip is being stressed.
