Overclocking Phenom II x6 1055t - Page 2

post #11 of 20
But to be completely safe, some heatsinks will be needed?
post #12 of 20
Thread Starter 
I don't have heatsinks on my VRM's, only thermal strips (whatever they do)
Excellent airflow though, the case is full of fans and they are all running at full 12v settings, not only that but it's about 13 degrees here so its the season to be overclocking.

I've now got it stable at 1.45V running at 4.2ghz all other settings have remained the same.

37 Degrees Idle

Next step, 4.3ghz

Will try with little voltage pushes and keep all updated.

keep us posted on temp2 and 3 mostlikely one of those is your mosfet.

Where can i find temp2 and temp3? only getting a cpu temp mobo temp, the AMD die temp which measures 10 degrees lower

and my gpu sensors.

I upped the voltage to 1.47V as the system froze running on 1.45V and its running a stress test now hitting 55 degrees under 100% load.
Seems to be stable.

What are you using. Actually it may be mobo temp... I'm not sure for ASUS. I use hwmonitor and it posts those as temp 1 2 and 3. idk what temp 1 is temp 2 is usually mosfet and temp three normally is non existant? Anyone verify that for me?

I'm using Hwininfo32, i've got a fan controller with temp sensors so i just went ahead then and put them on my mosfets and they aren't running really hot, hitting about 48 degrees under load

wow that is pretty amazing. I want to get a fan controller when I upgrade my case. 48 under load is very good. Do you have a fan blowing across them by chance?

Yeah a big 20cm fan blowing icy cold 5am winter air straight onto them.

I couldn't get any higher than 4.2ghz, i even tried 1.6v and had no candy.

So i just turned on turbo core and clocked that up to 4.5ghz and was like

That explains the temps then. 4.5 is close enough. Haha. Wish it wasn't summer here. I get up to 4ghz safely in the winter. Do you have a heat exchange outside?
post #20 of 20
ASUS motherboards have a PWM controller feature that will throttle the CPU clocks & voltage if the VRMs overload/overheat. However, considering this is pushing a 4Ghz Phenom II x6 and likely without any cooling at all (no heatsinks, and tower CPU cooler results in no airflow), this may happen repeatedly and frequently, causing adverse effect to performance.
You will want to ensure proper VRM cooling no matter what the situation, to ensure the best performance.
