Blue Screen of Death (barton 2500)

So I have recently overhauled my system. New Barton 2500, Asus A7n8x, Enermax EG365P-VE, 512MB Crucial 3200, and a Volcano 11+.
I have my system set to 2132 or 3000+ speed right now. The voltage core is at stock settings. The system runs a bit hot, but I'm a college studnet with no air so thats expected. It runs just fine, passes hours of prime95.
Now if I bump up the muliplier to 11.0 and keep the FSB at 200 it has all kinds of errors and generates lots of blue screens. Now in the past I have usually gotten blue screens with memory problems. Does anyone have any ideas what might be causing these problems? I have tried bumping the vcore up to 1.8 and it ran hot and failed prime95.

Thanks

A lot of the 2500's seem to max at around 2.1 GHz from what I've seen. We've ordered four of them so far (two retail, two OEM) and three maxed around 2.1 GHz and one made it to 2.3GHz. Two of the 2.1's have problems in Prime95 at 2.1 GHz unless the Vcore's are bumped pretty high. The 2.3 will do 2.4, but takes 1.8v.

My point is that perhaps 2.1 is just about the limit of your chip, especially in a hot room.

I need a insane 1.875v to get to 13x166 (my memory is doesn't like high freq). To get to 13.5 I need a 1.975 to be stable. This is all on air. My temp is 55C, but I don't care becasue it is still lower than that AMD retail fan which was 63C at staock voltage and speed.

have run my 2500+ at 2410mhz 11.5*210 with a high voltage, can't remember what it was, now I am at 2300 on stock voltages.
11.5*200

a gig of pc400 ram and nf7-s with latest bios, 16 I believe. slk900u running about 40c under load and 35c idle.

I also have the enermax 350w and I think it is about maxed.

You should be able to get higher than you are.

I could not get past 2100 until I flashed the bios.

Do you know the stepping of your Barton? The newer ones seem to be able to do around 2.3 - 2.4 GHz no problem (with a good heatsink of course). Also, is your ASUS board a rev 2.0 or 1.xx??? The earlier version are most likely to have issues with higher FSB speeds, whereis the 2.0 runs 200 no problem.

If you have the earlier revision board there are some things you can do to _make_ it work better at 200, but check first.

I have then new Asus board and I also flashed the board when I got it. The stepping are AXQDA 0323 UPMW which from what I have read should be a pretty decent chip.
