I had a Core 2 Quad Q6600 G0 and got that up to 4Ghz stable. I got an i7 920 D0 upgrade a few days ago and its been 'running in' fine at stock. Now i want to try overclocking it but don't know where to begin, there are a few options I'm not sure about regarding enabling/disabling, any help would be much appreciated. The ones in bold are the things I'm most unsure about. System Specs Intel i7 920 D0 @ 2.67Ghz (Swiftech Apogee GTX waterblock, First loop) ASUS Rampage II Extreme Corsair DDR3 1600 Mhz 3 x 2GB Kit Enermax Revolution 1250 Watt 2 ASUS Dark Knight 4870 512MB (Watercooled EK block, Second loop) ASUS Xonar DX2 PCI-E Here are the current BIOS settings Thanks guys
Although its for a P6T, I posted my setting in this thread a while ago. You should be able to translate that to your BIOS easily enough. Thats for a 3.8 OC. I have speedstep enabled though, so it will idle in a low power state. If you don't want that, then manually set the CPU multiplier. As a rough guide however, here's how I'd change your list as a starting point for a 3.8 OC AI Overclock - Manual CPU Ratio setting - 19 CPU Turbo-Power Limit - Disabled BCLK Frequency - 200 PCIE Frequency - 100 DRAM Frequency – DDR3 1600Mhz UCLK Frequency - 3400 QPI Link Date Rate - LOWEST SETTING - this has little effect on speed... UCLK above is way more important. DRAM Timing Control EPU II Phase Control – Full Phase Load-line Calibration - DISABLE CPU Differential Amplitude - 800mV Extreme OV - Disabled CPU Voltage - 1.34 CPU PLL Voltage - 1.8 QPI/DRAM Core Voltage - 1.35 IOH Voltage - 1.2 IOH PCIE Voltage - Auto ICH Voltage- 1.2 ICH PCIE voltage - Auto DRAM Bus Voltage - 1.65v (Must be within 0.5v of QPI voltage) DRAM REF Voltage - Auto Debug Mode - String Keyboard TweakIt Control - Disabled CPU Spread Spectrum - Disable PCIE Spectrum - disable CPU Clock Skew - normal IOH Clock Skew - normal C1E Support - Enabled Hardware Prefetcher - Enabled Adjacent Cache Line Prefetcher - Enabled Intel Virtualization Tech - Enabled CPU TM Function - Enabled Execute Disabled Bit - Enabled Intel HT Technology - Enabled Active Processor Cores - All A20M - Disabled Intel Speedstep Tech - Disabled Intel C-STATE Tech - Disabled Try that.... see how you get on. The link to my old thread at the top also has some useful info, so don't just look at the pics
thanks for that, i got it upto 4.2 stable now idle 37*C, load 69*C gonna leave it here for a week to let it run in some more and then see how far it can go. For everyday use im going to keep it at 4Ghz, perfect for my RAM speed.
