New motherboard now its time to overclock.


Recommended Posts

I recently purchased an ASUS A8N32-SLI Deluxe and have tested it for a few days at stock settings. As of right now all I have done is set the auto overclocking to 10% and my 3800 x2 is running at 2.2 Ghz. I've also ramaped up the speed of the RAM from DDR200 to DDR400 and set the RAM voltage to 2.7 as per RAMGUY's suggestions. Everything I throw at the system runs very smooth now. I want to push it a little bit farther maybe to 2.4-2.5 Ghz and the RAM is fine now but I would like to push it a little farther also. I am using Value Select 2Gig kit DDR400C3 and a VS1 Gig kit DDR400C2.5(I know that mixing RAM is a no no but it works for me). So If any one has any advice for overclocking my setup please throw it my way. (Please look in my PC specs for a full list of my system.)


Thanks in advance, hawk87

Hi Hawk,


Give this a try.


Advanced Menu


AMD Cool 'N Quiet Configuration

  • Amd K8 Cool'nQuiet : Disabled



Jumperfree Configuration:

  • AI Overclocking: Manual

  • CPU FSB Frequency: 250

  • SB to NB Overclock: Manual

  • SB to NB Frequency: 200

  • Adjust PCI-e Frequency: 100

  • PEG Link Mode: Auto


  • Over-Voltage CPU Vcore: Enabled (This enacts the 8-Phase power and adds +.2V to your Processor VCore)

  • Over-Voltage NB Vcore: Disabled

  • Over-Voltage SB Vcore: Disabled

  • Over-Voltage Hypertransport: Disabled

  • DDR VCore: 2.7

  • FID/VID Change: Manual

  • Processor Frequency Multiplier: 10

  • Processor Voltage: 1.25 (This is your processor Vcore. Keep in mind that the Over-Voltage adds +0.2v to your processor Vcore)

  • DDR Clock Skew: Auto


Memory Configuration:


  • Memclock Mode: Limit

  • Memclock Value 333Mhz (166Mhz X2) If you raise your FSB higher than 250, set your Memclock Value to 266Mhz. You are a bit higher as 240FSB X 10 with a 166 Divider gives you 200Mhz. You might well have to drop to 133MHz at 250FSB.

  • CAS Latency (CL): 3

  • Min Active RAS (Tras): 8

  • Row Precharge Time (Trp): 4

  • RAS/CAS Delay (Trcd): 4

  • Row Cycle (Trc): 12

  • Row Refresh Cycle (Trfc): 12

  • TRWT: 2 CLCK


MCT Extra Timing Mode: Manual


  • TREF (to DDR Input Strobe Skew): 7.8us

  • TWCL (to DDR Input Strobe Skew): 1

  • R/W Que Bypass Count: 8

  • Bypass Max: 4

  • Idle Cycle Limit: 16

  • Dynamic Idle Cycle Center: Enabled

  • DDR Driving Strength: Normal

  • Enabled 32Byte Granularity: Disabled

  • Twr: 3

  • DDR Input Strobe Skew: Disabled


User Config Mode: Manual


  • Read Preamble: 9.5ns

  • Async Latency: 11ns

  • Bank Interleaving: 8 - way

  • Burst Length: 4 Beats

  • Hardware Memory Hole: Disabled

  • DRAM ECC Enable: Disabled

  • L2 Cache BG Scrub: Disabled

  • Data Cache BG Scrub: Disabled




  • K8 to NB Frequency: 4 (800MHz) If you raise your FSB higher than 250, set to 3 (600MHz)

  • K8 to NB LinkWidth: 16 | 16|

  • SB to NB Frequency: 5 (1000MHz)

  • SB to NB LinkWidth: 16 | 16|


  • Primary Graphics Adapter: PciE1-->PCI-->PciE2 (if using first 16X PCI-e Slot)

  • Primary Graphics Adapter: PciE2-->PCI-->PciE1 (if using second 16X PCI-e Slot)


This will give you 250 X 10 = 2.5GHz. Test with Memtest and Orthos Prime. If stable then you can raise your FSB. Remember to lower your Memclock and HTT as mentioned above if you raise your FSB higher than 250MHz. You can raise your CPU FSB incrementally for the purpose of finding stability. I would personally not raise it past 1.55v. Watch your CPU Core temperature and keep it no higher than 55C on full Orthos load.


I would also test with 2 sticks and if stable then try with your other two sticks. You might have to play with this to gain stability with 2 X 1024 + 2 X 512.

The settings worked perfectly. I did not run Orthos Prime yet but I ran Memtest through one pass and no errors. I also ran 3DMark(all versions), Steam Source SDK Base, SiSoftware Sandra, PCWizard, and Super PI with no problems or hiccups. Now I need to overclock my graphics card to keep up with the new speed... or buy a new one :D:


Thanks for all the help! :praise:
