ctyper Posted September 9, 2011 Posted September 9, 2011 Hardware: Motherboard – Asus Rampage extreme - http://www.asus.com/Motherboards/Intel_Socket_775/Rampage_Extreme CPU – Intel E8400 Rer. E0 - http://ark.intel.com/products/33910/Intel-Core2-Duo-Processor-E8400-(6M-Cache-3_00-GHz-1333-MHz-FSB) – VID indentified by CoreTemp, is 1.25 V. Mem – OCZ Reaper PC3-12800 - http://www.ocztechnology.com/ocz-ddr3-pc3-12800-reaper-hpc-eol.html - as you can see in the OCZ Website, it says 7-7-7-24 @ 1.7 V., but in my mems, it says 7-7-7 @ 1.9 V., so I specified in my board settings 7-7-7-24 @ 1.9 V. Card – Gainward HD 4870 1GB DDR5 - http://www.bit-tech.net/hardware/graphics/2008/11/18/gainward-radeon-hd-4870-1gb-golden-sample/1 - Couldn’t find it on Gainward Website. Hi all! My name is Hugo, and I’ve been trying for a long time before asking for help, as I’m doing right now, to put this setup working. I’ve been reading lots of forums, tech reviews and explanations, everything I can find, but I can’t pass the setup I have right now, if someone could help, I’d be grateful. This is my current setup: CPU Configuration: C1E Support – Disable CPU TM Function – Enable Max CPUID Value Limit – Enable Vanderpool Technology – Enable Execute Disable Bit – Enable Core Multi-Processing – Enable Extreme Tweaker: Ai Overclock Tuner – Manual OC From CPU Level Up – AUTO OC From Memory Level Up – AUTO FSB Frequency – 375 CPU Ratio Setting – 09.0 CPU Clock Skew – AUTO NB Clock Skew – AUTO FSB Strap To North Bridge – 400MHz PCIE Frequency – 100 DRAM Frequency – DDR3 – 1500MHz DRAM Command Rate – 2N DRAM Timing Control – Manual CAS# Latency – 7 RAS# To CAS# Delay – 7 RAS# Pre Time – 7 RAS# ACT Time – 24 All other memory settings – AUTO DRAM Static Read Control – AUTO Ai Clock Twister – AUTO Ai Transaction Booster – AUTO Voltages: CPU Voltage – 1.18x Load-Line Calibration – Enable CPU PLL Voltage – (min.) FSB Termination Voltage – (min.) CPU GTLVref (0) – AUTO CPU GTLVref (1) – AUTO CPU GTLVref (2) – AUTO CPU GTLVref (3) – AUTO NB GTLVref – AUTO North Bridge Voltage – (min.) DRAM Voltage – 1.9x NB DDRVref – AUTO DDR3 ChannelA Vref – AUTO DDR3 ChannelB Vref – AUTO South Bridge 1.5 Voltage – 1.5 (min.) South Bridge 1.05 Voltage – 1.06 (min.) CPU Spread Spectrum – Disable PCIE Spread Spectrum – Disable These are the lowest settings (voltages) i found stable for this setup, Prime 95 for 24h. My objective is to run the memory at stock level, 1600MHz, but I’ve tried everything, voltages up an down and I can’t find a stable setup, or BSOD or Prime 95 fails. Can anyone help me? Thank you very much, Best Regards, Hugo Marreiros Share this post Link to post Share on other sites More sharing options...
dihartnell Posted September 9, 2011 Posted September 9, 2011 (edited) CPU volts looks low to get decent overclock. To get around 4GHz you will need around 1.36v for CPU voltage. You will need to punch your FSB up a lot more and adjust your mem strap accordingly. What sort of CPU cooling do you have?
