Overclocking AMD 64X2 3800+ Windsor AM2 Socket

My motherboard is the M2N-SLI Deluxe
CPU idles at around 27-30°C depending on ambient temperature, sometimes lower. On full load it jumps to around 38°C, again depending on ambient temperature. This is without overclocking.

I decided to up my frequency by 400mhz using a program called Ai Booster that comes with my motherboard. I didn't change the voltage of the CPU. (1.3volts)
Temperatures went to around 35-38°C, and to 45°C on full load. It seemed stable, but after playing Unreal Tournament 2k4 for about 2 hours my computer went off.... I've read about people taking this chip all the way up to 2.7ghz and beyond, a 400mhz OC seems pretty modest in comparison. Does anyone know what could have possibly happened?

I have stock cooling, and I'm using the thermal pad that comes pre-applied with AMD heatsinks.

PS. Last time I checked, the temperature was only 45°C before the comp went off on me.

Full system specs:
CPU: AMD 64X2 3800+
MOBO: M2N-SLI Deluxe
PSU: Thermaltake 430watt
RAM: 2x 1024mb modules of Corsair XMS2 DDR2 800mhz ram
Videocard: GeForce FX5500 PCI (very outdated)

 

I overclocked by changing the HTT from 200 to 240. I don't think I can change the multiplier..

 

You can change the Multiplier in BIOS ( Advanced CPU Configuration) Well, lower anyway, the CPU is upwards locked.

Your temps, what are you using to monitor temps?
Those Athlons have a rapid rise & fall ratio, so it best to use a utility that can provide real time temps, I use MBM5 my temps are displayed on my desktop as well as the system tray.

When OCing disable Cool & Quiet
For OCing CPU & Memory Avoid all software, OC via BIOS settings

I'd up the CPU to 1.4v , higher volts will increase stability, your Temps will also go higher, so aftermarket HSF might be in order
I'd also suggest Artic Ceramique thermal paste
If your wanting to get 2.7GHz I could see you running between 1.5 & 1.6v

To test Stability & max temp, run Prime 95 torture test for 8 hr or more without any errors, then run 3Dmark benchies.
Dual core users will run dual instances of Prime 95 testing both cores simultaneously


Your PSU is way under powered, I'm surprised you can even boot with it, not to mention it's a Thermaltake, Junk!
Sorry I gotta ask, why risk some good hardware on a shitty $30 PSU?
You need a PSU that can provide nearly twice as much amps on the +12v rail.
When a PSU burns out, it usually burns out other hardware too

Here's some reading, then ask your Q's

As for as PSUs go, when there are multiple 12v rails, you add up the amperage between them, correct?

ie, a PSU that has 2 12v rails and puts out 18 amps on each of them is the same as a power supply that has 1 12v rail and puts out 36 amps from the rail?

 

Yes (the +12v)

Short answwer Yes


OCZ make some Awesome PSU, two in particular are the Gamestream models 600w & the 700w both have four 12v rails at 18amp each (my next PSU will be one of these)



Seems like now days I OC everything! It's Addicting
I'm running three systems
Me #1 system I use an OCZ 520w PowerStream, it has 33 amp on a single +12v rail on my DFI Ultra D NF4, Opteron 146 10x276 at 2760MHz, 1.4v / 2x1gb G.Skill HZ's Samsung UCCC chips 250Mhz at 2.5v in DC / BFG 7800GT OC 256mb

#2 system An Antec True 480 it has two +12v rails at 18amp each, 36 amp total on my Asus A8N SLI Premium, X2 4200 10x240 at 2400MHz 1.4v / 2x512 Samsung TCCC chips 200MHz 2.7v in DC / XFX 6800Xtreem 256mb

# 3 system, running an Antec true 430, older model it puts out 26 amp on a single +12v rail, it powers my DFI Ultra B NF2, with XP Mobile 2600 9.5x250 at 2380MHz 1.7v / 2x256 Patriot XBLK Samsung TCCD chips 250MHz 2.7v in DC / Leadtek 6800 LE 128mb AGP Unlocked to 16 pipes & 5 shaders

#3 is For Sale
