GALAXY RTX 3090 HOF EXTREME limited edition evaluation original memory cooling design

1. Preface: It should not be the most expensive, but certainly one of the strongest non-public RTX 3090

RTX 3080/3090 uses GDDR6X memory for the first time. Its close to 20Gbps rate far exceeds GDDR6’s 14Gbps, but temperature and power consumption are also rising. It is rumored that the power consumption of RTX 3080 with 10GB GDDR6X memory can exceed 60W.

However, we compared many non-public RTX 3090s on the market, and none of the graphics card’s memory cooling design can satisfy us, until we got this limited edition GALAXY RTX 3090 HOF EXTREME.

There are three types of GALAXY RTX 3090 HOF series. The highest frequency is the RTX 3090 HOF OC LAB version. The Boost frequency of 1905MHz refreshes the frequency limit of the non-public RTX 3090, which is 210MHz higher than the public version of 1695MHz, and of course it is much higher. Competing in similar products.

GALAXY RTX 3090 HOF EXTREME limited edition evaluation original memory cooling design

As the flagship model of GALAXY, RTX 3090 HOF EXTREME has many unique design features:

1. Unique and high-efficiency memory heat dissipation design

Students who have used RTX 3090 should know that the GDDR6X memory temperature is difficult to control. The main reason is that the distance between the base of the heat sink and the memory is about 2mm. If this thickness is used with ordinary thermal pads, it is difficult to conduct heat to the heat sink.

I believe that DIY players know that the thermal conductivity of aluminum metal is as high as 237W/mK. When applying silicone grease to the CPU, the thinner the better, the thicker the silicone grease will affect the thermal conductivity, and the thickness of 2mm wants to have good thermal conductivity. Efficiency is tantamount to idiotic dreams.

GALAXY’s approach is very simple. It has a protruding design on the base of the radiator, and the part in contact with the video memory protrudes by 1.5mm. In time, it only needs a 0.5mm thermal pad. It should be known that the thermal conductivity of aluminum metal is as high as 237W/mK, while a better thermal pad is generally only 6~7 W/mK. The design of RTX 3090 HOF EXTREME fundamentally solves the heat dissipation problem of GDDR6X memory.

In addition, the metal back plate of RTX 3090 HOF EXTREME also has the same protruding design.

2. 6 8mm heat pipes + liquid cooling soaking plate

The cross-sectional area of an 8mm heat pipe is almost twice that of a 6mm heat pipe. The six 8mm heat pipe design of RTX 3090 HOF EXTREME is basically the highest specification of non-public RTX 3090 at present.

As for the liquid-cooled soaking plate, its cost is very high, generally only the public version will use it. The soaking plate can distribute the heat of the core to each heat pipe better and more evenly.

3. 26-phase power supply design + 12-layer PCB board

The high-end motherboards on the market usually use 8-layer PCBs, and the top graphics cards are 10-layer PCBs. The 12-layer PCB design of RTX 3090 HOF EXTREME can greatly reduce the signal interference between various electronic components, improve the electrical performance of the graphics card, increase the stability under high frequency and high load, and also help the GPU to impact higher frequencies.

In terms of power supply, the 22-phase core and the 4-phase video memory have a total of 26-phase power supply design, which can provide more than kW of power supply. In fact, some extreme overclockers have unlocked the power consumption of RTX 3090 HOF EXTREME to 1000W, and it can still run stably.

Since its release, the GALAXY RTX 3090 HOF OC LAB version has set a total of 16 world overclocking records and is the first NVIDIA GPU with a frequency exceeding 3GHz.

4. HOF Panel III full-color display

Many manufacturers now add LCD screens to their high-end graphics cards, but if they are actually placed inside the case, the LCD screen is mostly a display.

For this reason, GALAXY designed a HOF Panel III full-color display for RTX 3090 HOF EXTREME.

The HOF Panel III full-color display has a size of 4.5 inches, a resolution of 480*272, and a magnetic design that can be attached to the top of the graphics card. In addition, there is a bracket behind the screen, which can be placed on the case or on the desk.

GALAXY sent 2 data lines, one is the motherboard USB2.0 pin, if you put it in the case, you can use this line. There is also a standard USB interface data cable. When it is placed outside, plug this cable into the front USB interface of the chassis or the USB interface on the motherboard I/O backplane.

By default, this screen displays information such as the temperature of the graphics card, fan speed, core and memory frequency, and GPU power consumption. Players can monitor the running status of the GPU in real time.

In addition, you can also use the GALAXY HOF AI software to transfer pictures and dynamic videos. At this time, it is equivalent to an electronic photo frame.

5. Dual BIOS + Hyper Boost one-key acceleration

The RTX 3090 HOF EXTREME limited edition has two BIOSs, which can be switched by flipping a switch on the back. The acceleration frequency of RTX 3090 HOF EXTREME in P-mode is 1860MHz, and the Boost frequency in S-mode is 1800MHz. You can make your own choice between silence and performance.

In addition, there is a Hyper Boost one-key acceleration button on the bezel, and the GPU fan will run at full speed when pressed.

The 3x8pin power supply interface can support 525W power supply. Of course, if your power supply is good enough, you can also input higher power.

3 DP 1.4a and 1 HDMI 2.1 interface. There is also a Hyper Boost one-key acceleration button. After pressing it, a green light displays and the fan runs at full speed.

The liquid-cooled soaking plate + 6 8mm pure copper heat pipes can be regarded as the most luxurious heat dissipation design on the market.

The memory position of the backplane is also designed to be protruding, which avoids the installation of too thick thermal pad to reduce the heat dissipation efficiency.

The electronic components on the board are arranged very neatly, which seems to give people an inexplicable sense of comfort.

The video memory on the back of the PCB board is solid silicone grease. If you remove the graphics card backplane, these silicone greases will basically be scrapped and you need to buy a new thermal pad and stick it on.

5. Temperature and overclocking test: Boost frequency can exceed the terrifying 2000MHz

1. Temperature test

Furmark was used to test the RTX 3090 HOF limited edition, and the room temperature was 26 degrees during the test.

GALAXY RTX 3090 HOF EXTREME limited edition evaluation original memory cooling design

Set the parameters of Furmark to 1920*1080 resolution, 0AA, and the baking time exceeds 3 hours.

During the baking process, the power consumption of the RTX 3090 HOF limited edition is maintained at about 435W, the baking frequency is 1455MHz, the core temperature is 75 degrees, the Hot Spot temperature is 86 degrees, the video memory is only 78 degrees, the fan speed is 1776RPM, and the GPU power consumption is 435W.

2. Overclocking test

I thought that the core frequency of the RTX 3090 HOF limited edition is already very high, and there is not much room for overclocking, but the actual test results are much higher than our expectations.

After many attempts, the RTX 3090 HOF limited edition can pass various tests when the core frequency is increased by 140MHz. At this time, the Boost frequency has reached 2000MHz, which is 305MHz higher than the public version; Samsung memory can also be overclocked to 20.9GHz, the memory bandwidth It is 1001GB/s.

After overclocking, the 3DMark Fire Strike Extreme graphics score has reached 25866 points, which is an increase of 1872 points compared to 23994 at silent frequency, the increase is close to 8%, and the maximum operating frequency has reached 2160MHz. The maximum temperature is 57 degrees, and the maximum power consumption is 428W.

After overclocking, the RTX 3090 HOF limited edition can run 102FPS at 4K resolution of “Tomb Raider: Shadow”, which is 7 frames higher than the 95FPS of silent frequency, an increase of over 7%.

7. Summary: Is it worth selling 20,999 for top graphics cards?

Previously, NVIDIA’s GPU has been unable to check the memory temperature, and players have no way of knowing the actual temperature of the memory under high load. Fortunately, after the release of the new version of GPU-Z 3.7, players can finally see the memory temperature, and even the Hot Spot temperature can be displayed (previously only the A card can see these 2 temperatures).

We did a mining test a bit and found that the RTX 3090 HOF EXTREME limited edition exhibits long-term high debt, the temperature is only 90 degrees, and the power consumption is up to 271W.

In contrast, we tested a number of RTX 3090 models, and many models have a video memory temperature of 108 degrees when the computing power is 60MH/s. The RTX 3090 HOF EXTREME limited edition is the one with the lowest video memory temperature without changing the heat dissipation.

The overclocking capability of the RTX 3090 HOF EXTREME limited edition is also beyond our expectations. Its Boost frequency is already very high. As a result, it can continue to exceed 140MHz. The Boost frequency has reached a terrible 2000MHz, and the actual operation can reach 2160MHz. The horror of the design of the 26-phase power supply circuit and the 12-layer PCB board is evident.

After overclocking, the performance of the RTX 3090 HOF EXTREME limited edition can be increased by about 7~8%. At this time, its performance is already 12% higher than the public version. The air-cooled RTX 3090 can be more powerful than it. countable.

At present, the RTX 3090 HOF EXTREME limited edition is priced at 20,999 yuan. As a flagship graphics card with top-level workmanship and integration of many innovative designs, whether it is worth this price, I believe that every player will have his own judgment.
