Need help with stability

[zerga]

Hey guys I'm having some trouble getting stable on my machine. The specs are as follows:
AMD 3500+ 90nm core
MSI Neo2 Platinum
2x512 OCZ 3200 Platinum Revision 2
XP-90 with 92mm Panaflo
Antec 430W TruePower PSU

I was able to run at:
FSB 240
HT 4X
Multiplier 11
CPU Voltage 1.5v 3.3% overvid
Memory timings @ 2.5-3-3-8 1T
Ram voltage 2.8
AGP Lock 67
However in the middle of a game, I got a BSOD and it crashed. This configuration wasn't Prime95 Stable

I lowered some settings to:
FSB 220
HT 4X
Multiplier 11
CPU Voltage 1.5v 3.3% overvid
Memory timings @ 2.5-3-3-8 1T
Ram voltage 2.8
AGP Lock 67
Unable to get Prime95 stable...

Finally I'm stable @
FSB 210
HT 4X
Multiplier 11
CPU Voltage Stock
Memory timings @ 2-2-2-5 1T
Ram voltage Stock
AGP Lock 66
I'm kind of unhappy at the overclock results, but was wondering if there are major performance boosts gained by increasing the FSB? Would it be fine just to stick at my current stable configuration. But I would be happy if I can O/C it more while maintaining stabilty. Thanks for any input

edit:
Cooling is not a problem and I'm pretty sure my PSU is able to handle the voltages.

on the higher fsb things try turning ht to 3x and keep the agp lock at 66 and the pci one at 33?

How many PCI cards do you have pluged in?
