I have one of these chips on an Asus Sabertooth 990FX board and I was hoping to overclock it at least around 500MHz. How do I go about it with this chip? Can it be overclocked by the multiplier alone or is BCLK necessary? This is my first OC'ing an AMD chip as well as one with a dedicated northbridge chip on the motherboard.

Unfortunately the 1045T has a locked multiplier so you will have to OC it by changing the bus speed. This is a pretty simply guide that will walk you through it. As long as you have a descent chip 500Mhz should be very easy to get out of it on that board.<br><br>

EDIT:<br><br>
Try this one too.<br>

I have the same exact chip and I'm running a 39% OC on a Hyper 212.<br><br>
Unfortunately this seems to be the limit with my UD3 because this board really doesn't like FSB oc'ing. As someone here pointed out to me, phenoms prefer to stay in the low 50s so try to keep your temps at least below 55°C. My PC bluescreened after 12 hours of P95 when temps got upto the low 60s, but since this chip has a max rated temp of 71°C you do have some considerable oc'ing headroom.<br><br>
As for the guide, I don't feel good saying this but I used an outside source and it worked wonders for me, try the local links the guy above provided you with, and if they don't work refer to "Dolk's guide to the Phenom II". It's a fantastic guide IMO.<br><br>
Good luck!

Will a BCLK overclock be safe on this motherboard? If so, how much is safe?

Yes it is. As to how much, you're going to have to find it out yourself.

Exactly. Every chip is different. Go as high as you can as long as voltage and temps are in check. I got 3.7ghz out of my 1055T at 1.4v.

Im running my 1045T at 4Ghz stable on a crappy Coolermaster MX3 Cooler. Only things I had to play with was:<br>
Ram at 1600 Mhz, timings set manually.<br>
RAM Voltage at 1.75 (would not post with stock ram voltages for some reason)<br>
300Mhz FSB.<br>
Chipset voltages default.<br>
CPU voltage at 1.325 (calibration set to extreme, voltages goto about 1.45v when under load)<br>
My board is a GA-78LMT-USB3 (rev. 5)

and my chip wont go over 225fsb or about 3.0 no turbo boost. I get a 5250 in 3dmark 11. Volts only go up to 1.44. I can't change my NB clock so it's at 2250. Memory is oc to 1500 from 1333. 9 for timings, can't change them...does it auto. I don't know if it's me, or the chip really.<br><br>
board ECS 785gm-m
