It's possible but keep in mind the board still uses the older, cheaper 3-transistor MOSFET design from 2007-2008 (pre "Ultra Durable" era) and if OCP protection is present on the board we don't really know. 4+1 phases, no matter what conditin, are really not very ideal for pushing x6 CPU to the limit anyway. Maybe for the x4, but for an x6 we usually recommend you take the bigger power phase route.
Well the box says Ultra Durable on it....

The Ultra Durable era also brought in better VRM designs, though technically it stands for better caps, PCB, dualBIOS; I didn't refer to UltraDurable as being the better VRMs, but they did come around the same time as Ultra Durable - and this board does not have them. It recycles the 785G board designs from 2008, which is itself recycled from other 2007 & earlier boards, all of which have known VRM problems on processors with high TDP & core count. 3-transistor design, unheatsinked 4+1 phase, and problems on high TDP processors; the x6 is already TDP-heavy enough at stock, and you are planning to push it further and on aftermarket cooling that ensures the VRMs are completely uncooled. I don't recommend it. The board is rated 125W max with stock cooler, and for reason. I really suggest you don't push an x6 on this board for safety.

The 880GMA-UD2H, that'd be a good board due to the better VRM design (when you heatsink it), but this one, not at all

Well I'll grap some little heatsinks, that'll help.

That will help tame the heat and likely also the safety issues due to the tower cooler resulting in no VRM area airflow, however the power delivery would still not be as great as using a proper 8+2 or so; more phases = cleaner power = better overclocks, especially on high TDP processors.

VRAM heatsinks may be too big for the MOSFETs on that board. MOS-C1s or so may be of better size. Order as much as you need; there should be around 14-15 MOSFETs to cover.

Formula 20*200 OR 16*250

Voltage 1.45 Lower if passes

Do 20*200 first then do 16*250

Sorry I haven't updated, I've got it stable @ 4.0ghz with 1.44v
