This is in a HAF 912 with 4 120mm fans (two front intake, one intake on the side blowing air just under the video card fan's intakes, and one exhaust out the top back) and a 200mm exhaust out the top. My CPU cooler is a Cooler Master Gemini II.

I'm gonna go for 1GHz core later today so we'll see how it goes. I plan on finding how low I can go on the voltage at 900MHz core after for a more stable/long term OC.

My temp underload @ 925 1.055v it hits 63C in my Antec 1100, with 2 side 120mm fans blowing on it, 2 120mm front intake, 2 rear exhaust 120 and 200

That's about how mine is but it's always hot in the house so I have 4 exhaust 120mm side panel fans, 2 120mm exhaust on the back, one 120mm intake up front, and 2 80mm intake/exhaust fans, one on top and other on the bottom. CPU cooler is nothing special just the older version of this basically: http://www.legitreviews.com/images/reviews/1285/extreme_gear_hp1216b_001.jpg (Xtreme Gear)

You should be able to run at 900Mhz at stock voltage. Maybe a few more mV for it to be stable.

Is that 1.055V what you need to keep it stable? I was at those temperatures at that voltage but I dropped it to 1.038 and the temps went down and it ran stable.

I repasted my Classified but won't get the computer up until tomorrow since I'm waiting on a network card to come in. Moving my PC away from the router so I needed wireless =T DWA 556 hope it's worth it paired with my Airport Extreme.

my GPU-Z is stating my default volts are VDDC = 0.9130. under full load from furmark it reads 1.0000. does this seem low/?? seems like everything ive read has it above 1.000

these are the volts at stock 750mhz core as well as my latest artifact-free stress test of 915mhz (default everything except core and shader....915/1830 right now). from what the majority of all of you have been stating it seems that 1.000v at 915mhz is pretty low right? wondering if i need to go into bios or something?

to keep it stable at 925 yea

Hey everyone,

I'm a GPU overclocking "Noob". And I was wondering if could anyone help me smile.gif

I have EVGA Precision but I don't know how to use it well.

Anyone can help me with a safe OC?

Nothing too high that can risk my card.
:)

then dont touch voltage, novice Overclocking start 10-15mhz on the GPU core and on the ram, do one at a time. Each 10-15mhz you go up run OCCT for at least 30minutes, prefered at least 2 hours. You can also run Furmark torture test for 20 minutes if your card doesn't artifact or shutdown due to heat try the next increment. in OCCT keep the temp under 90C in furmark keep it under 95c, if it goes over this, adjust fanspeed

Well it looks like I might not reach 1GHz. Setting the voltage to 1.100v really pissed off the card somehow. Maybe someone more experienced might have some ideas? My screen ends up flickering green when running max voltage. I tried to make a run through 3DMark2011 at 1GHz core and no go at 1.100v. I thought I killed the card for about 10 minutes as the display just stopped receiving data from the video card but after letting it sit powered off for a few it came back on just fine.

However, 980MHz core and 1.088v worked just fine after I lowered the memory clock to 2050. I cranked out a P6931 in 3DMark 2011 with the highest Graphics Score (a 6877) I've seen for our cards so I'm pretty satisfied with that.

I've been lurking this thread since I got the card and I'm surprised there aren't a couple more of us Gigabyte guys yet. This card has continually surprised me coming from an old (twice oven bake fixed) 8800 GTX. That thing could heat a large room but my 560 Ti 448 sits comfortably at 28c idle all day.
Also I'm thinking about making the push for 1000 core and from what I've read as long as my temps are low and my voltage isn't maxed out yet I should be good to go?


Out of curiosity, what are your temps under heavy gaming? Those gigabyte cards have 3 fans right?

My stock voltage was the same as yours.... it's probable that my chip just isn't as good as your's. smile.gif
Yeah, the card's cooling was so well thought out... those fans can move serious air when they're cranked up all the way.

I agree, for 24/7 I would like to keep my voltage down.
So I'm letting it sit at 1.038V all day at 925Mhz, gaming temps of 51C.

i guess i got a lemon rolleyes.gif

And if 1.025V was your stock voltage (and you only bumped it up to 1.05V) then that's no lemon.
For mine to go to 950 I have to have at least 1.075 on the voltage.

the stock voltage is 1.0v which i cant change at all. even though AB is showing something else.

im only getting around 850-ish stable at 1.0v any higher i need more voltage.
