Hello,
Long time reader but first post. I appreciate any help you can provide.
I've been having an issue upgrading my PC with a new RX480. Both cards I've tried haven't worked:
PowerColor RED DEVIL Radeon RX 480 4GB (RMA back to Newegg)
ASUS Dual-fan Radeon RX 480 4GB OC Edition (currently have)
The symptoms were the same for both cards:
-PC powers up but does not display anything
-the fans spin up on the GPU and the LED power indicator turns on for the Asus card (PowerColor didn't have an LED)
-after powering on I can press the power button and it immediately shuts off (normally would need to press and hold during boot). This happens whenever the RX480 cards are powered and plugged in, including when I tried having both my GTX560 and the Asus RX480 running at the same time.
-did a deep clean to remove all drivers and still nothing
-tried both PCIe slots and reconnected all power cables in the computer
-looked up BIOS updates from ECS and only found CPU related updates, tried installing anyway and got an error saying "check for fused ME lock" (something like that)
I brought both in to test for DOA at local PC shop: tech said the PowerColor didn't post on his work bench (no power or anything). When I brought the Asus in, again it did not power up at all and he said maybe I'm frying cards. I told him it definitely powered up for me so he tested it in a PC he had set up and it ran completely fine with display out operating. He told me the test bench was PCIe 2.0 whilst the tower was PCIe 3.0 which must be the problem since my mobo is also 2.0.
This explanation doesn't make sense because I believe the PCIe standard is backwards compatible (correct me if I'm wrong). The only possible explanation I can find is that the RX480 is UEFI only and my BIOS is incompatible.
I appreciate any input and advice. Full specs are listed below.
PC Specs:
i5 2500
ECS P67H2-A2 V1.0 Black Deluxe
Corsair CX600 600 (replaced my old Coolmax VL-600B for the Asus card's 8-pin power)
PNY GeForce GTX 560 1GB (to be replaced)
Kingston HyperX Blu HS 8GB (2x4GB) PC3-12800, DDR3-1600MHz
Thank you.
