GTX 970 overclock results!
GTX 970 overclock results!
On my GTX 970 I increased the core clock to 120 MHZ with a boosted 1479mhz. My fans sit at about 50 percent during full load, and temperatures reach 52 degrees. I only raised the voltage by 15 MV and pushed power to 105%. I really like this card—please share your results below!
What's your card reference? I got my MSI gtx 970 up to 1556MHZ +225 core +550 mem around mid-50s c. Scored 1636 in heaven 4.0 @ 65.0 fps 1080p. Lovin' it. Absolutely amazing card for the price and I can't wait to get them in the future.
Run a benchmark like heaven 4.0 for a while.
It will crash or you will see artifacts if the OC is too high. Once you see no artifacts I would bring core and mem down a bit to stabilize it. I see no stability difference with voltage adjustment.
Some games are more demanding than benchmarks. I had to adjust down to +220 core +525 mem, seems to be ok now.
Run a benchmark similar to heaven 4.0 for some time. It may crash or show artifacts if the OC is too high. When no artifacts appear, I’d lower core and mem slightly to stabilize it. No major stability change noticed with voltage tweaks. Some games are tougher than benchmarks. I had to go down to +220 core +525 mem, which seems fine now. What’s your setup and voltage?
I’m currently at 1529mhz: +175 core, +300 mem, 110% power, kboost enabled but no extra voltage added.
It’s quite hot at 68°C under 99% load.
How's this for a first ever GPU overclock?:
Ran through Furmark, Heaven and Valley with seemingly no crashes or artifacts. Still downloading Crysis 3 for a real-world test.
I neglected to save the last Heaven result, but I believe it came out as 59.8fps.
Observed GPU boost clock was slightly higher, sitting at around 1447.
In Furmark, through multiple runs, I've never seen it go higher than 71c. 68-69 in the others; and it's pretty darn hot in here (I've taken off all my clothes.... ahuehuehue).
As a question though, do you think I should dial back the memory a little bit?
I'm a little bit concerned as to how it lacks any kind of heatsink and also how it's being serviced by only one phase.
I've got to say... this card man. It takes anything. I can't tell you how satisfying it is to hear a little 'click' about 20 seconds after finishing one of these tests as the fans turn off.
LittleKat shared their experience and suggestions for running benchmarks. They mentioned trying a benchmark similar to Heaven 4.0, noting potential crashes or artifacts if the Overclock is too high. Once stable, they adjusted core and memory settings slightly to improve stability without voltage changes. They found that some games are more challenging than benchmarks, requiring adjustments like going down to +220 core and +525 mem. They shared their current settings at 1529mhz: +175 core, +300 mem, 110% power, with kboost enabled but no extra voltage added. They reported high temperatures (68°C) under 99% load, and noted unusual voltage behavior—ranging from +50mV to 1250mV depending on load. They cautioned against leaving Kboost on, as it runs at stock speed regardless of load, and warned that increasing voltage on the MSI is uncertain and may not be necessary.
EVGA GTX 970 SC ACX 2.0 is currently running at 1512 MHz with a stock voltage of +120. Temperatures rise up to 72°C in FurMark, but the fan profile is capped at 50% and it operates quietly, which works well for me. The device starts at 1392 MHz out of the box, which is impressive. I haven’t modified the memory yet. Many users report negative experiences online, but I’ve noticed no coil whine and the system stays very quiet with a moderate fan setting. You can definitely push it further. I tested Heaven 4.0 and achieved 1977 FPS at 78.5 FPS using the default "Extreme" resolution of 1600 x 900 (not 1920 x 1080; I prefer to overclock with a window and burn-in at 1080).
