Help with Athlon II X4 630 >_<

Hi guys I'm new to overclocking and it's been a very frustrating week for me.

Here's my setup:

AMD Athlon II X4 630 CPU (2.8ghz stock)
Asus M4A785TD-V Evo motherboard (AM3)
Thermax Eclipse II 6 CopperPipe Heatsink (It's very good, big temperature drop vs Stock)
1333 DDR Ram (The label on the ram says 1600oc and I have no idea why)
Radeon 5750 1G DDR5


I've been doing alot of homework and my results are follows:

3.4Ghz Running stable max load with Prime95
3.5Ghz Crashing after 1 hour @ max load with Prime 95.

By default running at 2.8Ghz my CoreVoltage is 1.4 / NBVoltage 1.175
When I over clocked to 3.4Ghz or 3.5Ghz I set it at CoreVoltage 1.5 / NBVoltage 1.375

Been doing this all week and these are the settings that I don't crash so much with...

I haven't had a crash yet at 3.4Ghz, but I think I have my core voltage higher than what it's suppose to be... what I

mean is I see people running stable at 3.5Ghz with only 1.14 Core V....

I'm sure my Voltage on my Ram or chipset might need adjustment, or HTLink Mhz as well but I have no idea what the

values should be...

Here's a screenshot of my CPU-Z

I would like to run at 3.5Ghz or more, do you guys think it's possible? I need more knowledge on other settings other

than just the Core Voltage and NB Voltage adjustments >_<

1.4v vcore is at stock... yes I'm not kidding.

I got it to stable at 3.5ghz with 1.52v finally. But if I go 3.4 I know I can go much lower... but even at 2.8ghz (stock) the vcore was 1.4v set by bios default... am i suppose to lower this? -_-

Is something cooking?

You should drop your HT Link speed to 1600MHz/8x. Keep it at 2000MHz or so (or in your case, 8x250MHz when over-clocked).

Your RAMs and IMC/NB are great. Dropping the HT Link speed might allow you to dial-back the CPU volts. You can bump the NB VID to 1.2-1.25v if necessary for 2500MHz IMC/NB. Don't do 1.375v NB! That's where a bunch of your volts is going. You should be at CPU 1.425v to 1.45v unless your chip is really junk.

It is probably the worst Athlon quad for oc'ing, though (a C2 stepping with low multiplier), 3.5GHz with the IMC/NB at 2500MHz is quite good.

Try to lower your core. Make sure to turn off auto vcore settings

The volt swing is not uncommon with Asus motherboards like yours. Yours looks to be 1/3 of some I've seen so there is not much to do about that.

I think you've hit the AMD volt wall. What are your volts/temps at 13.5x250MHz?
