Spetter Posted August 25, 2008 Share Posted August 25, 2008 Manual settings: Dram Timing Control: Manual CAS Latency: 7 RAS to CAS Delay: 7 RASS PRE time: 7 RAS to RAS Delay 7 RAS ACT Time: 20 Everything else in Ram configuration: auto PCIE Frequency: 100 Voltage: DRAM Voltage: 1.90856 Everything else in voltage: Auto CPU Spread Spectrum: Disabled PCIE Spread Spectrum: Disabled Everything I did not mention is set to: Auto At the moment I am runing: FSB Frequency: 333 with CPU Ratio setting: 10.0 FSB Stra to North Bridge: 333MHz DRAM Command Rate: 2N Those configuration will give me a option DDR3-1333MHz in DRAM Frequency. And CPU speed are detected as 3.33GHz (the orginal speed, but Ram is FSB 333 1333mhz and not FSB 400 1600Mhz And this configuration is stable in Windows I cannot Find any divider option in bios (CPU / ram) so I cnanot set cpu Ram at 5:4 ratio (333 FSB cpu, 400 fsb RAM) So, is there possible to set CPU at FSB 333 with 1333Mhz and RAM at FSB 400 with 1600Mhz ? Or must I overclock ? I have tryied FSB frequency at 400 and FSB Strap to North Bridge at 333Mhz with every voltage set to auto exept DRAM Voltage. DRAM Frequency gets detected at DDR3-1601Mhz CPU gets detected at 4.02Ghz That configuration gets unstable and I have tryied FSB frequency at 333 and FSB Strap to North Bridge at 400Mhz with every voltage set to auto exept DRAM Voltage. DRAM Frequency gets detected at DDR3-1332Mhz CPU gets detected at 3.33Ghz That configuration is wrong then since RAM detected at DDR3-1332Mhz and not 1600 When I try the X.M.P option in bios (Ai Overclock Tuner option) (grayed out): Profile information: 1600MHz-7-7.7-20-2N-1.90V CPU Ratio Setting: 10.0 FSB Strap to North Bridge: 333MHz DRAM Command Rate: 2N DRAM Timing Control: Manual with setting 7-7-20-7 CPU Frequency gets detected at: 4.02 GHz FSB speed gets detected at: 1608Mhz With the XMP option and a CPU Ratio setting at: 8.0 - CPU get detected as 3.21GHz that is still wrong regarding the CPU. (bios detects it as 3.21 meanwhile Windows Wista 64 bit detect it as 4.00GHz) Or is this my only option if stable ? Underclocking cpu to get a fsb 1600 for the RAM ? Any suggestion ? Is my only option to overclock something ? And what voltage in ant option is prefered ? What are prefered to change in Bios to get the most optimal settings ? Or should I run both FSB and North Bridge to 333. And wait until maybe I get a FSB 400 cpu (expensive) ? Link to comment Share on other sites More sharing options...
