Overclocking the EVGA GeForce RTX 3070 FTW3 ULTRA GAMING

How do you overclock a EVGA GeForce RTX 3070 FTW3 ULTRA GAMING video card? 

Before we begin to overclock, we need to find out the real-world in-game GPU frequency the video card is operating at by default.  That way we can find what frequency we are overclocking from and how much gain we get in overclocking.  Keep in mind that NVIDIA GPU Boost already adjusts the GPU frequency dynamically to utilize most of the potential that is there.  This means it will already clock the GPU frequency well above the quoted Boost Clock even without overclocking.

Default Clock

The base clock on this video card is 1500MHz, which isn’t very helpful.  More importantly, it is the GPU Boost Clock that makes the difference and it is set at 1815MHz on the EVGA GeForce RTX 3070 FTW3 ULTRA GAMING.  This is 90MHz higher than the Founders Edition GPU Boost of 1725MHz.

The EVGA GeForce RTX 3070 FTW3 ULTRA GAMING settled in at 1980Mhz during testing and maintained a temperature of 59 degrees Celsius. Comparing to the Founders Edition that averaged 1935MHz, the EVGA GeForce RTX 3070 FTW3 ULTRA GAMING checked in 45MHz faster.  Memory in both the Founders Edition and the EVGA GeForce RTX 3070 FTW3 ULTRA GAMING is set to 14GHz using GDDR6 memory.

Highest Stable Overclock

To dial in the maximum overclock for the EVGA GeForce RTX 3070 FTW3 ULTRA GAMING, we used EVGA’s Precision X1 software that makes lots of knobs to turn and levers to pull available for tuning enjoyment.

We started by maxing out the Power Target at 111% and boosted the GPU Temp Target up from 83C to 89C. We then cranked the fans up to 100%. There was not a knob present for modifying voltage, however, given the low power budgets on the RTX 30 Series that we have seen so far, adding voltage has not been necessary as it only increases power consumption and reduces how far GPU Boost will push the core clock speed up.

With the power matters settled, we started by pushing the core clock up as high as it could go without touching the memory side of the equation. We were able to pick up an extra 150 MHz on the slider offset before we started crashing.

Next up, we set the core back to stock and boosted the memory to see how far we could take it. It appeared to be happiest at +405MHz (+810MHz effective). This is a boost to 16GHz GDDR 6 over the stock of 14GHz GDDR6.

Putting it all together, this gave us a final stable overclock of 1650MHz core clock, 2000MHz boost clock, and 16GHz memory clock.

Comparing the sustained GPU frequency to the stock frequency, we see that the observed overclocked frequency averaged out to 2145MHz. This is a 10.8% increase over the stock clocks and stock Founders Edition performance. The memory at 16GHz is 14.2% faster than the stock clock as well.

  1. I’ve been on the queue for this card since december, at least I know what to expect. :rolleyes: :rolleyes:

  2. Well EVGA is probably my favorite AIB, not because they don’t make some mistakes, always have the best card but they have by far from my experience the best service out there. Their forums are actually useful and full of tricks, OCing and so on. Plus EVGA does not mind you installing coolers, water blocks etc. on your card. They will sometime offer OCing bios with much higher power limits at times particularly on the FTW3 and above cards. This card has a much better feature set over the AMD 6700XT except the 6700XT has more VRAM. Probably comes down to what one can nab in the end, hard choice.

  3. Nice review.

    I don’t think this is the one for me, not that anyone can buy them for msrp anyway.
