i have a AMD 1100T BE and its been giving me hell this is my first computer build and i kinda went all out and well at first i had the thing over clocked to 3.8 then pushed it up to 4.1 when got an aftermarket heatsink and fan all my specs are below and well after i over clocked it to 4.1 i ran a stress test for 5 hours and it had no problems so i figured i would never push it that hard and stopped the stress test by the way i used prime95 and it was working out great for about 2 weeks cpu never went above 37c on idle and even while playing crysis 2 maxed out the cpu wouldnt go over 49c and i even did some 3D rendering on Vue9 and it was fine but then i tried to use media coder to transfer a mkv file to an mp4 and every time at 70% i would get the blue screen of death then after a few tries it would say only 5 cores were unlocked instead of 6 and it just became unstable so i re flashed the bios back to default and i really want to get the most out of this system as i can but i just cant seem to make it stable when i try to over clock it can anyone help me?
 
You using prime95 blend? Try prime95 smallFFT.

What settings are you at for 4.1ghz? Meaning what bus clock and multiplier, and what Voltage?
Have you changed the North Bridge speed or voltage at all?
 
its was blend i was using and

core voltage i had set to 1.40
the multiplier was at 20
and bus speed i had set to 205
i also had upped the Dram voltage to 1.6
and the NB voltage to 1.4
 
with all that i was setting at 4.09Ghz and im using CPUID to monitor everything at idle my cpu temp was any where from 36c to 42c depending on the room tempeture and while it was runing prime95 blend it never got about 62c
 
I doubt it's enough Vcore. Prime95 isn't the best stress test. The average for 4ghz is around 1.425-1.45v. You seem to have a slightly better than average chip to be mostly stable at 4.1ghz at 1.40v, but I'd still bump it to 1.425 and see if it's still unstable.

Those temps are actually pretty high though. Do you have enough case ventilation?
 
yeah i have a nzxt phantom so all the cords are out of the way for good air flow i have a big aftermarket heat sink and fan i plan on adding another 200mm exhaust fan soon tho to help pull air out
 
Sunbeam doesnt release how many true watts and amps that are on the 12V rail. Its not a true dual rail, so you cant add the rails together. The 31 amps is just the max any (one) rail can pull before it trips. My guess is it has around 500/550 watts on the 12V rail with around 40 amps total on the 12V and thats max.
 
I'd have to agree, its probably comparable to a good quality 500-550w unit. Thats a little light for an 1100t overclocked with a 5870. But it's not all about handling the load either, the ripple in the rail is probably pretty bad with a poor quality PSU trying to handle that kind of wattage which is causing the instability.

New PSU time!

This corsair will be far better quality and be plenty for your current hardware-

But if you want a little future upgradeability, perhaps 5870 Xfire or whatever I'd bump up to the 750-

The 1100 could just need more voltage. But regardless I would see about getting a better power supply either way.
 
Id just grab the TX750, its a solid supply and you get a nice bag with it too c.c i use it to store my RC car transmitter, a 3PM-X by Futaba heh
 
+1 to stranglehold's suggestion on the silverstone, I also didn't know you'd be willing to spend that much.

Thats the silverstone I have, and let me tell you it's handled everything I've thrown at it. Intel hex core overclocked to 5ghz with tri-fire 5850's! And of course it's modular which is awesome for cable management.
