3800+? That's 2GHz stock, and I assume running a /5 divider for the RAM (800MHz dead-on). Jacking it up to 230MHz FSB will OC the CPU to 2.3GHz - fine, but the RAM divider will stay in place and drag the RAM up 15% as well, to 920MHz. If that G.Skill is regular 5-5-5-15 it might not like being pulled too high especially at stock 1.8v, and even if its 4-4-4-12 (low-latency modules usually have more overclocking headroom) it won't enjoy thrying to run such tight timings at 920MHz.
Try dropping the RAM to 667MHz in the BIOS (in real life this simply forces the CPU to use the /6 divider, 2300/6 = 383, so at 230FSB the RAM will be at 766MHz) or even boosting vDIMM and loosening timings, if the BIOS has those options available. Then see how far you can push the CPU. Don't forget to drop the HTL from *5 to *4 past 230FSB, and to *3 past 260FSB (you might not want to push it that far as 260FSB = 2.6GHz on the 3800+)
If you can't drop the HTL from the BIOS, then (motherboard-dependent) you might have a hard limit of ~266MHz on FSB, any further and no Windows (d'oh!). Oh, and you'll be stuck using a utility to drop the HTL every time you get into Windows... it might not be stable with a HT of 1.3GHz+...
