Hybrid Cooling An RX480 Nitro+ By Sapphire.

 

The goal was to hit 1500 Mhz. I achieved 1450.  The one the benchmark run for 1500.  I got a BSOD Video TDR Failure and this persisted through several reboots. It never got above 55C. The card is now running 1340 at 1.08V because I only really wanted a quite card.

 

Before I started I needed specific information on the board I'm using. 

This video gives us an idea of the operating range of the VRM, and it basically just needs some airflow. the same should be true for the Vram but I have small heat-sinks for them both anyway. 

 

Lets get started

 

I am using a NZXT G10 and a Corsair H70

 

Disassembly of the card. The Back plate screws into the Fan shroud through the PCB. The heat sink is fastened directly to the PCB

 

A quick test fit shows that one of the Foam up stands for the G10 get in way of the power connector. So I removed it. 

 

Install these heat-sinks to the mosfets

 

Install these heat-sinks to the Vram. Some of these are not centered on the chips because of the clearance issues with the AIO. 

 

 

 

Assemble NZXT G10 Normally

 

Install

 

I don't have the Bench-marking scores because I seriously thought I fried my card trying for 1500 Mhz. I may update this post with 1450 Mhz results for Timespy, Firestrike, and Catzilla at a later date if I get requests. For Most Gaming loads this setup does not exceed 50C on the GPU and the Noctua fans keep it quite. The pump is wired directly to a Molex Power adapter for a fan and just runs 100% all the time.  And the VRM fan is attached to the case fan hub.

This is my First time doing a write up LMK what I did right/wrong, if this was helpfull, and if it's even in the right place.

If you want high OCs, get the BIOS that's quoted in this video

Sweet thanks I need this to pass the 1.5GHz mark. Its locked for me. Its not going to help him much.

I got 1495/2100 with 50% power  and 96+ voltage

*Cries in the corner how my £120 Asus Strix RX470 can only do 1350MHz with memory downclocked due to how it only has a 6 pin PCIe connector*

 

And yes, at 1400MHz, my cut down P10 chip consumes 190watts underload...not including how ever much the vRAM chips need when technically it can only supply 150Watts...although I have a XFX XTS 1kW PSU ;-;

If I get brave  later I may try that bios and I'll be a little more methodical than simply turn the dials up and see what happens. I did figure out that the persistent video error was probably my unstable overclock being applied on startup
