Quad r290 (x flashed) 2nd card stuck at 2d clocks

[watanabe]

I bought a total of 7 r290s back when they were $399 (+ sold 6 bf4 codes for $30 yippee) and 4 of them flashed to X's. Those are goin in my workstation to mess around w/and hash on. They will be under water but having waterblock leak issues so for now they are on air.

After a bit of a misshap I finally received a replacement motherboard today and about to get everything going, but having one of the cards stuck at 300MHz. I've tried afterburner v17 beta, disabled ULPS, nudged mhz bar a bit and hit apply, but nothing's getting this card out.

Wondering if it may be power related? I'm running on an enermax maxrevo 1500w and each card is on a separate rail, only other hardware in the machine is 1 ssd, 1 3.5" green drive, and an assortment of fans.

Any ideas on how to wake this guy up?

Which EK blocks do you have for them? What was leaking, the block itself or something else? I am very curious since I have now gotten 2 defective/sub-par copper blocks for my 290..

i had the plexi version. Leak seemed to be coming from between the quad link terminal and the card.
