Overclocking EVGA RTX 3080 FTW3 HYBRID

In order to overclock the EVGA GeForce RTX 3080 FTW3 ULTRA HYBRID GAMING video card, we are using the manufacturer-provided overclocking software.  In this case, it is EVGA Precision X1.  This is our highest stable overclock shown below. 

EVGA GeForce RTX 3080 FTW3 ULTRA HYBRID GAMING Video Card EVGA Precision X1 Software Overclock

How do you overclock the EVGA GeForce RTX 3080 FTW3 ULTRA HYBRID GAMING video card?  Well quite easily actually.  First, we simply raise the Power Target, which unfortunately is rather small at just 5% over default or 105% versus 100%.  This doesn’t leave a lot of power headroom.  We can also manipulate the fan speed separately, but for our OC purposes, we set them to 100%.  Then it was just a matter of dialing up the memory and GPU frequency.

Our final clock speed consisted of an offset of +150 to the GPU clock and +1000 to the memory clock.  For the memory, this brought us up to 21GHz from the default of 19GHz.  This brought the bandwidth up to 840GB/s.  For the actual GPU clock frequency increase look below.

With +150 on the offset, it brings the actual real-world frequency up to around 2040-2060MHz from the default 1935MHz.  That’s about a six and a half percent overclock from the stock factory GPU Boost or 125MHz.  This isn’t the highest overclock we’ve seen on a GeForce RTX 3080, but it is still commendable.  The limiting factor for overclocking this video card is the power limit/TDP.  There just isn’t a lot of headroom with the small 5% power limit increase it allows. 

When you overclock VRAM, in this case, GDDR6X, that consumes a lot of board power which can take away from the maximum GPU frequency.  If we leave the memory alone completely and leave it at 19GHz we could squeeze a little more out of the GPU, about 2075-2080MHz at the extreme here.  The thing about this overclock, is that either way due to the AIO the GPU temperatures are excellent and the sound profile very low.  The GPU is not held back at all thermally, it is only held back by power limits.

GPUz

The temperatures shown in GPUz show why the AIO is preferred for overclocking.  Yes, we are running the fans at 100%, but only to ensure the highest possible overclock.  With this maximum overclock GPU Temperature stays at a low 51.5c and the Hot Spot is at 63.8c, so this GPU is well cooled.  In addition, memory, which when overclocked can get very hot, is only at 74c, which is a really incredible temperature for the memory overclocked at 21GHz.  We can also see all the other iCX temperature points for memory modules and power delivery, and all of them are at incredibly, and I do say incredibly, cool temperatures for being pushed to their limits on overclocking.  This is just, well cooled, what can we say.

  1. Thanks [USER=3]@Brent_Justice[/USER] for another awesome review. A truly impressive card. I’m constantly at ends in deciding if I want to mod, and then invest in everything it takes to get a top-end custom loop setup going but things like this make it easy for people, when they can get one. Now granted once done most parts can be reused for future upgrades but it is a bit of money and time to do so. I priced around a $1K to upgrade my Strix 3090 to full block, and all the other parts, and never committed to it.

    In terms of the power limitations it’s an unfortunate common design choice that I’ve noticed with most manufacturers to use reference, or similar, PCBs and not include a BIOS that will allow for greater adjustments. I couldn’t tell you how much time I spent looking for a 3090 with a factory loop that also included one of the custom PCBs that allowed for increased power. Other than the Kingpin and FTW3 Ultra Hydro, and some mythical things from overseas, I never did find anything else. Pretty much everything I saw had the standard 2x 8-pin connectors.

    However the FTW3 Hydro 3090 appears to use the same 240mm radiator as the 3080 and I have doubts if it would still perform as well as what you saw with the 3080 when fully overclocked. Really seems like they should’ve used a 360mm with the 3090 but can’t say I’ve read any in-depth professional reviews like yours to examine it in-depth.

    In either case I’m on the list for one of the FTW3 Ultra Hydro and who knows, maybe when the 4090s come around someone will offer one and it’ll be accessible.

    Bottom line though is that these 3080s look to be the cream of the crop and if someone can get at MSRP they’ll be in for a treat.

  2. I have a standard FTW3 Ultra Gaming, no doubt it is a good card.

    I have a custom loop and a EKWB block on the GPU.

    Even running the standard stock cooler, I had no need to overclock the GPU.

    The stock cooler is very quiet. I had to really convince myself it was worth the time to put a block on.

    At any rate, I think it would be interesting to run an air cooled Ultra vs this watercooled Ultra and see if there was any real advantage to paying extra for it.

    In reading other reviews on similar things, on other sites, generally the performance is very similar when using stock clocks. The big difference comes down to noise levels and when overlocking it.
