I really like what you're doing. I assume that OC is on stock voltage? My preferred technique is unlocked CPUs with Throttlestop software to control multiplier and Voltage. Although the T7400 will be BSEL and VID pinmods. The2006 Dell Dimension E520 in my sig. shows what this method can do. I sent a link from here to a guy at Tomshardware who is trying to get a W3690 to work in a T7500.
Keep up the good work.thumb.gif

Nice. I would look for ICS chip on the board if you can find it? Yeah it cut out the Integrated SATA so I use PCIe SATA cards for all my drives while overclocked & everything works fine... So keep that in mind the Onboard SATA cuts out.

VESA mode 103? I'm not sure what that is... The AMD R9 390X won't support BIOS Post over Displayport 1.2 to hdmi 2.0 for 4k 60hz but works over HDMI alone so that's strange...

BIOS Modding the 390x is a breeze using Hawaii Bios Reader & ATIWinFlash v277
