What causes instant Prime crash?

[InorganicMatter]

Specs in sig

250MHz * 14 = 3500MHz
CPU/RAM = 5:4
RAM Timings = "Determined by SPD" (2-3-2-8 I think)
2.8V on RAM
1.5125V on CPU
45.5C Idle
55.5C Load

Prime95 crashes instantly, but the system seems to be 100% Windows stable otherwise. The voltage on RAM is the highest the motherboard offers, but the CPU can go all the way up to like 1.8 or 1.9 (don't remember). What gives? Is this the roof?

 

[Budwise]

its not stable, plain and simple.

*cough* Yes, I think this much is obvious. My question was what is causing the instability, and what can I do to improve the stability? Move vcore? Less MHz? Manually set RAM timings?

Well, Your temps are OK, so try upping the vcore a bit.

If that doesnt work just lower the fsb
