390 Question

[TSGrayson]

I ordered a computer from a boutique dealer with two MSI 390x in crossfire. I received the computer today and it says 2x390 in device manager and says the same Radeon Settings. Core clock is 1005MHz....did I get two 390 or 390x?

Run GPU-Z and check the shader count. If it's 2560, then you got 390's. If it's 2816, then you got 390x's.

2560!

2560!

Time to check your invoice, I suppose.

Rebooted and ran it again for a picture and it says 2816 shaders now....hmmm...any idea what would cause it to change?

Old version of GPU-Z? 0.8.6 is latest.

Also, the 290/390 have 64/160 ROPs/TMUs while the 290X/390X have 64/176.

now back to 2560...

Not sure what the heck is going on..

I would run DDU (Display Driver Uninstaller) to nuke the current driver installation, and then install the 15.7.1 drivers (or the latest non-Crimson set).

Avoid the latest Crimson drivers - apparently there's a fan profile bug that is potentially cooking cards.
