10chris Posted February 19, 2009 Share Posted February 19, 2009 DerekT can you please post your bios settings? I have core i7-920, rampage 2 extreme (805 bios) and TR3X3G1866C9DF but i can't make them work at 3.8 ghz the cpu and at 1900mhz the memory.Please be specific with all the settings you use.

DerekT Posted February 19, 2009 Share Posted February 19, 2009 Be sure to set your memory to the second, fourth and sixth slots.Download Memtest86+ V2.11 from--->Here Download CPU-z from-->HereEnter your BIOS, load setup defaults, save setup defaults and set to these values.AI overclock - Manual OC from CPU level Up - Auto OC from Memory level Up - Auto AI Overclock Tuner - X.M.P. CPU Ratio setting - 20 CPU Configuration CPU Ratio Setting - 20 C1E Support - Disable Hardware Prefetcher - Enable Adjacent Cache Line Prefetcher - Enable Intel Virtualization Tech - Enable CPU TM Function - Disable Execute Disabled bit - Disabled Intel HT Technology - Disabled Active Processor Cores - All A20M - Enable Intel Speedstep Tech - Enabled Intel Turbo Mode tech - Disabled Intel C-STATE tech - Enabled BCLK Frequency - 190 PCIE Frequency - 100 DRAM Frequency - DDR3-1900MHz UCLK Frequency - Auto QPI Frequency - Auto Dram timing control: 1st Information 9-9-9-24-x-x-x-x-x-x DRAM CAS# Latency - 9 DRAM RAS# to CAS# Delay - 9 DRAM RAS# PRE Time - 9 DRAM RAS# ACT Time - 24 All the Rest to Auto EPU II Phase Control - Full Phase Load-line Calibration - Auto CPU Differential Amplitude - Auto Extreme OV - Disabled Voltages Cpu Voltage - 1.40 (Lower after finding stability. I found 1.36v) CPU PLL Voltage - 1.82v QPI-Dram Voltage - 1.52v IOH Voltage - Auto IOH PCIE Voltage - Auto ICH Voltage - Auto ICH PCIE Voltage - Auto DRAM Bus Voltage - 1.656v DRAM REF Voltage - Auto CPU Spread Spectrum - Disabled PCIE Spectrum - Disabled CPU Clock Skew - Auto IOH Slock Skew - AutoBoot to the memtest CD and test for two full passes. Then, if stable, enter Windows and post your CPU-z CPU/Memory and SPD tabs in screenshots. Now I set to X.M.P. and the only changes I really made to the memory and CPU was that I set the multiplier to 20 to first find stability. This disables the turbo function as that can be a problem when first determining the quality of the CPU and its stability. I then remove Hyperthreading as I find it adds a good 10C to the CPU thermal and doesn't really change the performance of my system use. I then enabled C-State tech and set to 7. I left the timings set to X.M.P. and did not change them. I did, after determining full stability, set to 1T and found it stable. That was about it.

DerekT Posted February 20, 2009 Share Posted February 20, 2009 I already did. Keep in mind, that it's the CPU that determines the ability of the interface between the CPU and On CPU Die Memory controller. Some can NOT make 190 BCLK, some can make 200. The next revision of i7 should be more smooth. Get a boot first. Set to 160BCLK and those settings. Then incease to 170, 180, 185, 186, 187... Those are my settings. I am using the 1104 BIOS though. DerecT could you send me the bios settings you use in order to run cpu at 3.9ghz and memory at 1900mhz.I have the same hardware as you (I7-920, RAMPAGE 2 EXTREME, CORSAIR 3gb 1866 C9 kit), but if i try to run dd3-1900 with BCLK:190, CPU MULTIPLIER:20, CORE VOLTAGE:1.38 or above, DRAM VOLTAGE:1.65 and the other settings at AUTO it doesn't post and the LCD poster says LOCKED.

Thank you very much DerecT.I have sent you another private message accidentaly because i hadn't see your post.Just ignore it. Link to comment Share on other sites More sharing options...
