X6 Downclocks/Undervolts/Core Disabled "Review"

post #1 of 8
Thread Starter 
I made this thread about the curiosity about people who Downclocks/Undervolts/Core's Disabled. Please feel free to post what ever your "Power Efficiency" settings as this may help people who may want to put a HTPC together with a X6 Phenom II

CPU: AMD Phenom II X6 1055T / Motherboard: ASUS Crosshair IV
FSB: 200
CPU: 2800MHz - CPU VCore: 1.1V - 3 Cores disabled
NB: 2000MHz - CPU-NB: 1.0V
RAM: 1333MHz CL6-7-6-18-20 1T - DRAM: 1.4V

CPU Idle temp: 24-30C / Load Temp 33-34C (Depending on room tempature) Please be aware that my CPU hasen't been lapped correctly from using the wrong grit paper, and will be corrected by 2500 grit soon.

Final Thoughts:
Iv'e managed to cut down my idle wattage from 154W to 118W (Includeing the 80% from the PSU) which is read from my watt meter that I have my computer plugged into. Having 3 cores disabled on my 1055T does not affect game performance in anyway, even though there is a slight FPS drop, it's not enough to give me any sluggish game play.

Prime95 load wattage: 212W / Just Cause 2: 286W

Iv'e managed to cut enough power off from the CPU to maybe disable the fans on my radiator which will give me more of a quiet experience whilst watching Blu-Ray movies on my computer.

I hope many of you will find this interesting.

I actually don't have a comment on the OP itself but I was wondering what grit paper you used when lapping that affected it negatively... you're saying you are going to use 2500 grit. It is my understanding that the very very high grits like that are mostly just used to polish the surface and the flatness is achieved mostly with the 600-1k grits. My guess is it has something to do with any tiny tiny scratches being removed to reduce air bubbles?

Sorry for the hijack

I used p30 and p60 at the time then I use a 600 grit paper which still leaves microscopic scratches all over my CPU which you can visually see and so I need to use a 2500 grit to rid of them for good

I don't know about power usage figures, but when I decided to go for maximum efficiency per volt on my 1055T I managed to do 3.2GHz on 1.12V (NB at 3GHz), which yelded a load temperatures of 33ºC on the CPU and 38ºC on the GPU (overclocked to its limits) with the radiator fans at around 5V (barely audible).

Is your CPU and GPU on the same loop?

My CPU generates alot of heat :/ not sure why..... It might be because I'm using the XSPC RS240mm Radiator..... I might just have to upgrade to a 340mm Radiator

Of course they are tongue.gif

A 360 for a CPU only is a complete waste dude tongue.gif


About your loop, have you tried to go lower volts on higher speeds?

My CPU is a dud with high speeds, but when it comes to low speeds (3-3.4GHz) it manages with an awesomely low amount of volts smile.gif


Try optimizing that vCore on higher speeds, you might be surprised smile.gif

4.0GHz @ 1.44V
NB 3000MHz @ 1.37V

Max Prime95 load: 51-53C

the 2 fans on my rad are connected to my mobo and set at it's highest, it's the standard fans I had with the XSPC Rasa kit though.

Pump is on 12V Molex too.

Do you think that adding a 120mm radiator to my 240mm radiator loop might help a little?
