Tweaking my Amd X2 4800+ Asus A8N32-SLI Deluxe

Recommended Posts

With 4GB of RAM you are going to have to run a very heavy divider and you will lose the ability to gain great performance from that CPU overclock. Your DRAM has already dropped to deal with the memory controller's inability to run 4 X 512 at optimal dram settings and timings.


Please post your CPU-z CPU, Memory and SPD tabs. Upload the screenshots to an image upload site such as http://www.photobucket.com

Hi Derek

Many thanks for replying to my question.

Sorry for the delay as i work away all week.

When it comes to building the system im ok but when it comes to overclocking im a newbie.

I took note of what you said about the 4GB of ram and have promptly taken 2GB out.

I have taken the Cpu-z information that you required and posted them on photo-bucket.








I am very grateful for your time and help,hoping that you can assist me in my quest to tweak my system.


Regards Scott

This will give you 250 X 11 = 2.75GHz. Test with Memtest and Orthos Prime. Keep in mind that this is just a testing setting and very likely not your final overclock.


You can raise and lower your CPU FSB incrementally for the purpose of finding stability. I would personally not raise your Core Voltaage past 1.55v. Watch your CPU Core temperature and keep it no higher than 55C on full Orthos load.

Just changed all the bios settings as above and rebooted.

All 4 fans came on as did the power led but that was it.

Took out cmos battery and replaced it and promptly restarted back to factory settings.

Any ideas?


Also memclock would only go to 250Mhz not 333 as above


Is there a possibility that the v-core voltage at 1.20 is too low as the machine wouldn't boot

Set your memclock to 166. Your board sees 333 as a multiple. ie 333/2 = 166. Your core voltage is not 1.2v. It is set for 1.2v and there is an overvoltage option:


Over-Voltage CPU VCore: Enabled (This enacts the 8-Phase power and adds +.2V


This option adds 0.2v to your Vcore and initiates the 8-Phase power. You end up with a Vcore of 1.2 + .2 = 1.4v. If you set your Core voltage at 1.4v and did not enabled the Over-Voltage option, then you would be running at 4-Phase power. 8-Phase is found to bring more stability by helping to normalize the sine signal when overclocking. This helps deal with the effects of electrostatic migration and/or discharge.

I tried the new settings and the computer wouldn't boot up again,its beginning to be abit of a puzzlement. I have also noticed that the 3500LL Pro shows a maximum bandwith of PC3200(200 Mhz) in CPU-Z is there a reason for this.


Thanks again
