HELP OC an X3 720 BE AM3 on a Biostar TA790GX A3+

post #1 of 13
Thread Starter 
Hello. I came to these forums in search of answers that the outside world can not give me, at least not the people I talk to. I am not only new to overclocking but to PCs in general so my abilities and knowledge are severely lacking for what I try to accomplish.

I have been trying to OC my X3 720 AM3 on a Biostar TA790GX. All examples I have seen around the web are OCs with the AM2. I dont know if that is where the problems start or not but the "easy" OC feature in the BIOS will not let me do anything that my PC will actually boot up while settings are changed.

I was told to just change the multiplier from 14 but am unable to do so in the BIOS. Then told to change the MHz on the BUS speed I believe from the 200 it is set at to 250 and that just gave me a bunch of blue screens and startup issues. I lowered it to 240 and 230 and still wouldnt work. Went lower and got farther in the start up but still wouldnt work. I believe error says something along the lines of "Too many cold resets due BIOS POST, may be due to overclocking error" changed back to normal and resumed fine.

Sorry so long and if anyone could please help me I can give you more details.

Start MUCH slower when OCing the Bus speeds. I currently have mine at 215. You should know that when you increase your bus speed you are affecting both the cpu speed and the ram speed. Therefore you will need to increase the voltage for both the cpu vcore and the northbridge. Also, since you have a 720, you can enable ACC and possibly unlock a 4th core(make sure to up the vcore a little bit if you BSOD at first). You should look up some "How to" guides on Phenom II OCing. They will help a lot.

Thank you for your help. I was searching around random places today and came across the information I needed. The multiplier I was looking to change was under an option CPU FID. Did not know that meant multiplier at all but after enabling the Custom P States I was able to reach the setting to change it.

So I took it from the stock 2.8 GHz and moved it to 3.2 and then ran prime95 for a little over an hour and the maximum temp on one of the cores was 68 while the core temp stayed around 62. I am very excited to have achieved my first overclock. Even so I wont push it too far since I am running the stock AMD heatsink. As soon as I order a new one I will push my limits hoping to reach at least 3.6. I'm guessing that will take a voltage change which I am not familiar with but I'll find it somehow.

As far as unlocking the 4th core I have tried. Not saying I did it right cause I knew even less then than I do now, and thats not a lot. I do want to go check out the links you have givin me and try again to unlock it. The first time required an RMA baack to Biostar as none of the options they gave me to repair it worked. Hopefully I will have more luck this time.

Thank you again for your response and your help. And again sorry so long.

Well you have a pretty big problem then, the Phenom II chips have a max temp of around 60C. Most people keep them well under 60C. Mine never hits more than 50C.

I just went to the AMD product comparison page where they let me look at the full specs and they have it listed as 73C as well. And its been running normal for a few hours now.

Considering you're running at 3.2G and getting temps like that.... I would pull back the OC until you get some better cooling....

That's a nice cooler and it will help alot,however even the stock cooler should never get that hot with that overclock.Make sure you know the correct way to install your heatsink before you re-do it.
