OCing and wrong reports in Vista

I wanted to do a basic OC on my X2 3800+ from 2.0ghz to 2.4ghz tonight to prep my rig for STALKER (can't get enough of just the thought of that game). So I went into the BIOS on my ASUS A8N-SLI Premium, upped the CPU Frequency to 240 x 10, lowered the HTT multiplier to x4, and upped the vcore to 1.4. System loads (has a tendency to fail when booting after the initial saving and exiting BIOS, but after that it works fine), I'm in Vista right now without any problems thus far, only Everest Ultimate Edition 2006 reports the CPU frequency at a paltry 2014mhz. If I reboot and go into the BIOS, it reads correctly at a solid 2400mhz.

Question is, what's to blame? Did I OC wrong, is Everest reading it wrong, is Vista bad at interpreting clock speeds, or is it something else? I normally wouldn't put so much stock in Everest, but doing the benchmarking tests it includes yields results on par with a normal X2 3800+.

Anyone have any ideas? Or perhaps a different yet still reliable monitoring program?

Thanks.

[Edit] Backed down to normal speeds, reads correctly. Also downloaded a different program when it was still OC'd, gave me the same report, ~2000mhz instead of 2400mhz.
 
I don't know much about amd's but have you used cpuz? Also could it be coolnquiet
 
I've read something like Vista has it's own bios and overriding some overclocking settings that you do before the startup. It sounds bullshit but maybe it's only about monitoring correct speeds. You may try to do some benchmarks and see the difference between default and oc'ed settings.
 
Well like I said, I did the benchmarking things in Everest, but I dunno how reliable those are.

I downloaded CPU-Z, but it's not telling me anything new since I clocked it back down to stock speeds. I'll try it again when I get home.

Cool'n'Quiet is disabled, and the only thing installed off the ASUS disk is the temperature probe; didn't bother to install the AI Overclocker or anything like that.

I'll see what else I can find; if anyone else has any ideas, let me know.
 
Ok, so I OC'd and checked CPU-Z. It says that it's running at 200 x 10 with an 800mhz FSB, rather than the 250 x 10 / 4x HTT settings I put it at in BIOS. I can't figure this out. Whenever I reboot and go into BIOS, the settings are exactly as I put them. Is this a problem with Vista, or something I don't know about?

Any help is appreciated.
 
It just says I'm running at the default speeds for my 3800+ X2, 2000mhz. This is regardless of what I set the multiplier to, the CPU bus, the HTT multiplier, etc. Booting into BIOS shows the speed I actually set it at, but in Vista all it seems to do is decrease the FSB to 800mhz rather than increase my CPU speed.

[Edit] Yes, my motherboard has the latest BIOS revision that is Vista-capable, 1009.

Here's a screenshot of cpu-z while overclocked:
