Would anyone know why my computer shuts down when I raise the Bus. It only shuts down when I raise the bus when overclocking. Here is my stats now:

Multiplier x19
v-core voltage 1.48775
Bus 200
HT 200
NB 2400
ram 1600mhz


edit, not just when overclocking.
 
Solution


Because your multiplier has been raised from the default 15X = 3000 to 19X = 3800

FYI> CPU Electrical range = 0.85v - 1.425v (According to AMD website)

Also TDP = 95c (According to AMD website)

(Full detailed specs haven't been posted at AMDs website yet regarding the X3 740, just sales specs, I'm sure AMD will get around to listing the full specs soon.)

Be careful pushing that Vcore much further, make sure your load temps are good and not the reason for the shut downs

when windows xp starts loading. Heres my components:
Asus M4A77TD MOBO
Phenom II X3 740 (Ocd' 3800)
G-Skill Ripjaws PC3-12800 (1600 MHZ)
ATI Radeon 4670 ( 1GB DDR3 )
OCZ Stealth X Stream 700 W PSU
Zalman 9700 110mm CPU heatsink fan w/heat pipes. (Runs around 50 c when load for a couple hours)
 
At windows loading I'd say either core voltage or the RAM is OCed too high, which I've commonly noticed causes a crash after POST but it could be either... try raising you RAM timings by 1, or try selecting a slower speed just to see if it boots then. If it does, you know where the problem lies and if it still has the same issue, then it's likely something with the CPU OC although it might potentially be something else. Hopefully an AMD expert can give you some better advice than me.

yeah, when I tried to raise the bus the first thing I did was drop my NB to stock and maded sure the mem was ok. I think its the ram I have because my mobo doesnt support 1600 unless its 1066 or 1333 ocd'. The ram I have is 1600 mhz so thats probably the problem. I tried downclocking to 1333 and then raising the bus and HT and NB all at once and no luck either. If I have my own selections open in bios they all adjust with each other ( I.E. BUS, HT LINK, NB)
