This overclock seems impossible.

Hey everybody! I haven't posted here in awhile since I haven't been doing anything notable lately, but I have been lurking and this is still my most favorite computer forum.

However, here I am with a new thread, and this may seem lame by the end, but it's really confusing me, so I hope I can get a little advice between all the n00b jokes ;)

After burning out my Chaintech 9CJS last year, I sold off all of my components and decided to upgrade to an LGA775 board. At least, that was the plan. All of my money ended up going straight into my car instead, and I won't go into detail, but I should have just bought the computer. So here I am now with an MSI MS-6758, a P4 3.0e (same as my last cpu), and 2 gigs (2x1gb) of G.Skill DDR-500. Then, the overclocking adventure began.

I'm running V2.4, which was the last BIOS release. I started from within, upping the FSB by 5mhz per reboot, keeping the memory ratio at 1:1 and leaving the voltages alone. At around 230mhz FSB, I corrupted my startup.ini and had to do a repair install. It only got worse from there. The memory is rated to run at 2.8V, but I couldn't change that without more instability. Same with the CPU Vcore. I slowed down all the SPD timings, tried to keep voltages in check, but nothing at all would let me boot into a stable desktop.

So, I gave it a rest for about a week and started re-reading all of the stickies that have helped me so much before. I decided to try a software OC this time because it seemed like something wrong with the mobo was holding me back. I installed ClockGen, SpeedFan, and ThrottleWatch, then started my OC procedures like normal: add 5mhz to the FSB, run Sandra with Processor Arithmatic, Processor Multimedia, and Memory Bandwidth 5 times, then repeat until failure. Only this time, my little smoking hot P4 hit 3.9Ghz before it finally stumbled and crashed. It just didn't seem right, I mean, I never even touched the voltages! So I ran SuperPi at my previous speed, 3.8Ghz, and it finished in 36sec. My temps never rose above 51C (thanks to the ZALMAN CNPS9500 and Arctic Silver 5?), and I'm sitting here typing this post without a hitch while WMP11 plays "The Office" in the background. CPUz shows 3.8Ghz, and so does ThrottleWatch. However, when I reboot my BIOS shows the clock at 3.15, just like System Properties and Sandra's own info pages.

Here's a pic of the screencap I took right after my last burn-in test and SuperPi 1M completed:

What do you guys think?

Oh, and just for fun, here's my beautiful beast:

AAAAGGGHHHH THE WIRES WILL KILL US ALL!!

but no, that's not impossible. mosdef improbable. maybe you just got one helluva a chip
 
Hah, I know, it's pretty messy. But the way the PSU is set up and where all the compenents are that need power there's really nowhere else for them to go!

And speaking of helluva chip, the story of its delivery makes it seem even more impossible. I bought it off of newegg unboxed, and when I opened the package I discovered that the CPU had fallen out of its tiny plastic cage, and half of the pins were bent. So I got in there with my mechanical pencil, straightened them out and plugged it into my dead mobo to make sure they were all straight. The I sent newegg a little complaint, and they offered me $12 off my next order. It was nice that they at least did something.
 
It's an acryic case with gloss black painted on the inside. The case looked really bad with the grills on, and I couldn't find anything online that interested me. I didn't really want dragons, skulls or bio-hazard symbols popping out everywhere. I think it looks really clean now (besides the inside :( )
And no, I don't have any kids around here, but there is one cat that doesn't sniff it so closely anymore.

Ouch ;). Nice overclock by the way, it's pretty damn impressive for a cheap board and a S478 Prescott.
