My Corsair Twin XMS 3200C2PT isnt oc-ing at all.

I dont know why but my Corsair Twin XMS 3200C2PT (512x2) isnt oc-ing at all. i used to be able to hit like 210mhz. now i cant hit anything more than 200mhz without crashing really quick.
like 5 months ago one lady hit a power pole outside my home and shut the power down and (probably, im not really sure) ever since then this has happened. if that incident was the cause why is it even working now? wouldnt it be all dead or all good?
how high did you all hit with this memory on unmodded a7n8x? thanks.

my rig is:
amd athlon xp mobile 2600 200x12 prime95 stable
ZALMAN CNPS7000B-CU 92mm - diode high 56 (during heavy prime), low 27
asus a7n8x rev 2.00
Corsair Twin XMS 3200C2PT (512x2) - year and a half old.

Did you run memtest before?

yeah its stable at 200mhz.

Is it still stable @ 200mhz now?

yeah its stable at 200mhz. but when you go up like 203 it crashes.

Did you recently switch to a new motherboard? Did you recently lower your vcore?
