here's my screenshot if it helps you a bit.

That screenshot is showing that the CPU is pulling about 1.336v, of course this is not 100% accurate but that is nowhere close to 1.5v@ 3.8Ghz
Another thing is that you normally have to set all your voltages to get a stable system, you cannot leave the NB on Auto, well at least not on the boards I have used... Auto is normally used when you are at stock clocks.... Once you push the CPU past 1.4v it is recommended that the NB voltage be more or less the same as the CPU voltage. Note: It differs on every mobo but I am just giving you an idea....
Yes, try dropping the multi and raising the FSB and check temps... you should be able to get at least 220 and your Ram of course will be running a tad faster as well....
yes, whenever i aim for the 4.0ghz-4.2ghz+ range i have to boost my fsb speed. to keep it steady i must increase the nb voltage.
The screenshot indicates the CPU is operating at around 1.336v, which is far from the expected 1.5v at 3.8Ghz. It’s important to configure all voltages for a stable system; leaving the NB on Auto isn’t recommended, especially with boards I’ve used. Once the CPU exceeds 1.4v, the NB voltage should match the CPU voltage closely. Keep in mind this varies by motherboard, but it gives a general idea.
Try lowering the multiplier and increasing the FSB to see if temperatures drop—this should help boost performance slightly.
Thanks, testing now.

Let me know how it goes and remember to check your temps every now then...

One last question. Is it voltage or HT voltage? If I push the NB close to the CPU voltage, I see it going red because it's running at 1.112V. Should I be pushing the HT link instead? This bio is way different from what I'm used to.
adjust the nb in small steps. don't rush to match the cpu voltage immediately. on my msi i change the nb voltage. I haven't tried the ht yet.
He can modify the NB voltage to match the CPU voltage and it should work as long as he avoids over-volt... I've tried this on the same MSI Platinum you mentioned, which is similar to the board you're using with ATM.
Please now, She LOL
I followed your advice to adjust the voltages. Still struggling to achieve stability even at a lower O/C without setting the Bio's to 1.38v to 1.40v @ 3.6GHz. It's really stuck on this one.
Do you think the temperatures might be limiting my performance? The heat escaping under load comes off the radiator, but the mesh on top of the case seems to be restricting airflow. It appears to be pushing the hot air back around the radiator and pulling it back through. At 3.6GHz with a voltage of 1.38v, I'm reaching 48C (118F). The room temperature is between 72-73F, while idle temps are around 96-98F.
