sp0da Posted August 16, 2008 Share Posted August 16, 2008 Hello - I have an Asus Maximus Extreme (BIOS 1104), that I just cannot seem to get stable. The system will remain stable until gaming, where it runs great for a couple of hours some days, or less than 15 minutes on others. :[pouts: System specs: CPU: Intel E6850 (watercooled using Dtek Fusion V2, Swiftech MP655, and Thermochill 120.3 rad) RAM: Corsair TWIN3X2048-1800C7DF PSU: PPC 750 GPU: eVGA 8800 Ultra Case: Thermaltake Armor BIOS Settings are: Advanced: CPU Ratio : 9.0 (have tried at 7 and 8 - won't boot) C1E: Disabled CPU TM Function: Enabled Vanderpool Technology: Enabled Execute Disable Bit: Enabled Max CPUID Val.

FrostyPaws Posted August 16, 2008 Share Posted August 16, 2008 With my limited experience with overclocking I've been told to set voltages manually especially for core voltage and NB voltage.... I'm not sure how much the maximus extreme differs from a rampage but I know my board overvolts considerably. Its a lot of trial and error with voltages I've been at it a few days trying to lower everything as much as possible while still running stable. DDR3 though... jesus I take it cost is no object? Just pay someone to do the overclock for you :P Link to comment Share on other sites More sharing options...
sp0da Posted August 16, 2008 Author Share Posted August 16, 2008 Thanks, Frosty. I have tried manually setting the voltages with the CPU and NB with mixed results. Any suggestions on what voltages to start at? Currently, in Vista right now, Everest is showing the CPU at 1.09v. Link to comment Share on other sites More sharing options...
sp0da Posted August 21, 2008 Author Share Posted August 21, 2008 Ok, seem to have gotten a little more stable with upping the CPU voltage manually, but I still get some stability issues. Any ideas? Link to comment Share on other sites More sharing options...
Yellowbeard Posted August 21, 2008 Share Posted August 21, 2008 Ok, seem to have gotten a little more stable with upping the CPU voltage manually, but I still get some stability issues. Any ideas? What voltage have you tried? For 400FSB+ on a 65nm CPU you are probably going to need 1.35v or more to get there. Link to comment Share on other sites More sharing options...
