. Here's what you need to at least get you STARTED:
250 x 14 = 3.50GHz, 1.44v (shouldn't need more than 1.425v, but 1.44v is fine)
10x NB multiplier, set the CPU-NB voltage to 1.30v.
8x HT Link Multiplier
Knock your RAM divider down to 5.33x or DDR3-1066
Set stock timings for your RAM, give them a SLIGHT bump in voltage (like 0.05v)
That'll put you at 3.5GHz, 2500NB, 2000HT, and DDR3-1333 right on the nose. Almost any Athlon II 630 can take that EASY.
From there (once you get the above stable), knock your RAM down to 4x (DDR3-800), and go for more. Increase vcore as needed (keep under 1.55v, keep temps below 55*C).
To get 3.7GHz out of that chip (assuming its like mine and takes 1.55v to get there), your RAM would either be at DDR3-1407 or DDR3-1056 (5.33x and 4x respectively). You could also try other settings as well, lowering your multi and going for a higher bus clock...which will get that DDR3-1056 up higher.
You've got tons of options. I can tell you right now, its likely a RAM timing or voltage issue...or it could be that your CPU-NB voltage is set to stock 1.175v, and your NB is clocked pretty far.

~3.46 = 248 bus clock
248 x 5.33 = near 1333Mhz for memory
Since it's a 4GB generic DIMM it's probably not going to go any further. You might want to add DRAM voltage, but only if you can justify it by increasing speed further or lowering timings.
Even a C2 Athlon II x4 should be able to manage at least more than that
Most C2 Athlon II 630's SHOULD handle 3.6-3.7GHz easy. I've got a pretty bad stepping, and I can pull 3.7. I've seen others as high as 3.9 stable, but they were native Deneb cores as well.
