I am trying to overclock to achieves the best voltage and BCLK ratio. my current settings are Ai Overclock Tuner: XML CoreRatio: 21 BCLK: 180 VCore: 1.275 DRAM V: 1.5 Auto for the rest Temp Stable @ 70~75 Prime95: Stable for 12 hours so far! Questions: 1) on CPU-Z(Memory) my DRAM Freq shows 540 mhz, how do I push it up to 800mhz? Every time I manually set DRAM Freq, it will cause BSOD. 2) at CoreV: 1.25 I manage to get 21multipier x 175 BCLK, is there anyway to push to BCLK higher without increase the VCore?

You have the famous i7 920...a great overclocker. Here are the steps to overclock the unit: 1) Set the vCore to standard. 2) Increase the Multi by 10x every time you POST after change. 3) every 10x, increase Vcore by 1 incriment. 4) Set DRAM to about 1.6,( or whatever the OEM required to set.) 5) monitor temps with CPU-Z 6) If you get a BSOD, enter BIOS and check the Timing. It should be about 7-7-7-21, 8-8-8-23, or 9-9-9-24. 7)Increase voltage V Core and DRAM 1 Increment at a time when increasing multi. Now, to answer your questions: 1) You can increase your Frequency by increasing your DRAM voltage. make sure you have a 'stable' timing,( no random #'s) 2) You could but, you run into instability and may result in a BSOD.
