OCZ Memory on A7n8x Deluxe V2 Mobo
My system is:
My system is: a7n8x Deluxe V2.0 / Uber bios R1005 sata enhenced Barton XP 3200+ @ 2400 (200x12) `Very Stable' OCZ PC3500 EL Dual Channel DDR 2x256 set Thermaltake VOLCANO 9 300 watts power supply. Plenty of case cooling. Randon All-In-Wonder ATI 9800 Pro WinXP Pro SP1 CPU temp runs constantly between 40c and 45c OCZ recomends the following settings: http://www.ocztechnology.com/support/motherboard/43 "Recommended settings for the OCZ PC3500 EL Dual Channel DDR is with the FSB set to 166 and the memory asynchronous at 217Mhz ( 217x2 = 434Mhz ) with the timings of 2-3-7-3." But, on another page of thier web site, they recomend this: http://www.ocztechnology.com/support/performance/ "PC3500 EL-DDR 2 3 3 2 (217MHz)" They are posting thier #'s in reverse, so the last # is the CMD Rate, first # is the CAS. Thier site states that I should be able to do this with the a7n8x mobo. But for the life of me, I can't. I spend a whole night and part of a day trying. If I drop the fsb to 166, there is no way to get back to 2400MHz. The closest I can get is 14x166=2324MHz. A 14.5 multiplier is not available (I'm being nit-picky here). And what in the world is a multiplier of 7.0x/15.0x, 8.0x/1600x, or 8.5x/16.5x? All of these are multiplier options;does this mean I can choose one or the other? I tried the 7.0x/15.0x multiplier, and it multiplied by 7.0x. Is there a way of choosing the 15.0x mulitiplier? My bios settings are below. I have posted all the settings in the "Advance Chipset Features", because, if I leave something out, someone is sure to ask for it. CPU External Freq......................................200MHz Multiple Setting........................................... ..Menu CPU Multiple.......................................... .......12.0 System Performance.................................User Defined CPU Interface......................................... ......Optimal Memory Frequency....................................By SPD Resulting Frequency.................................200 MHz Memory Timing...........................................U ser Defined SDRAM Active Percentage Delay.......6 SDRAM RAS to CAS Delay...................3 SDRAM RAS Percentage Delay.........3 SDRAM CAS Lantency..........................2T FSB Spread Spectrum...........................Disabled AGP Spread Spectrum..........................Disabled CPU VCore Setting.................................Menu CPU VCore ..............................................1.67 5v Graphics Aperture Size.........................64mb AGP Frequency.......................................Au to System Bios Catchable........................Disabled Video Ram Catchable..........................Disabled Chip Voltage Control.............................+1.6v AGP Fastwrite......................................... .Disabled What am I missing here? Thanks for any help. |
