Upgrading GTX 980ti with Zotac Amp Extreme SLI for newcomers
Are there any recommended settings for overclocking these GPUs? Right now I'm using MSI Afterburner with these values:
110 Power
+100 MHz (memory)
A very cautious fan speed curve
Later I might include screenshots. Here are my specs:
i7-6700k
16GB DDR4 3000
ASUS Z170-AR
Zotac Amp Extreme GTX 980ti SLI
EVGA Gold 1300w PSU
No GPU is identical, you need to test your specific cards yourself. Just a note, you’ll see better gains by overclocking the core clocks first, then check memory performance. Before pushing memory, focus on the core boosts. Start with a 15-20Mhz increase and run tests like fire or heaven to confirm stability without crashes or artifacts. Continue adjusting until you reach consistency. When instability appears, reduce the core speed by 5Mhz and retry to discover the optimal setting. My card reached 1443Mhz out of the box, allowing a core boost to +100 before encountering DX11 driver issues and hardfreezes.
Without a GPU, you need to evaluate your specific cards yourself. Just a note, overclocking core clocks gives better results than memory, so begin there and identify your peak before adjusting memory settings.
Check your card’s performance when under load. Begin by boosting the core clock by 15-20Mhz and test with fire or heaven afterward to confirm stability without crashes or artifacts. Continue this process until you reach a consistent result. If instability appears, reduce the core clock by 5Mhz and retry to discover the optimal setting.
My card reaches 1443Mhz from out of the box, allowing a core boost to +100 before encountering DX11 driver issues and freezes. After adding memory, I had to slightly lower the core for stability. Currently I maintain +75 core with +450Mhz memory, achieving 1528Mhz/8000.
Maxwell cards are highly sensitive to temperature, so keep your GPU cool and ensure proper case cooling. Voltage increases have minimal impact but can occasionally provide a small stability boost.
Hope this information is useful and good luck!
