Ok looks like I ought to try it am running an i5 3570K at stock on an Asus P8Z77-V board I have the RAM set at 2400 so where do I go in the EUFI BIOS to ramp the CPU up say to 4GHz? (It's turboed at 3.7 now)
John, this it the best overclocking guide I know of.
Ivy Bridge Overclocking Guide ? Asus Motherboards. Don't worry about the type of board they use. All Asus boards have the same basic overclocking options. Set your board the way they have their board set. You may want to save your current profile in case you want to go back to it. The guide will explain some of the terms in bios and what they do. They're are very few you need to change. Disregard their Dram frequency, voltage and the CPU vcore. You will have to use your own. Just set the timings and Dram voltage and frequency for your ram. You will want all the C states enabled if you set your Vcore to Manual. When you move to offset set the C states to C1 as enabled, C3, C6 and C states Package to disabled. It is very time consuming to set a high overclock, so just be able, but in the end, it will be worth it. Make sure you have Cpre Temp, CPUz and IBT, Prime95 or AIDA64 installed. Just remember when you run them, your core temp will go way up. That's normal. In normal usage you will never see even half those temps. Just try to keep your temps while stress resting to 95C or below. Set your Vcore to manual and set a vcore. I start at 1.250 and run prime for about 30 minutes at a multiplier of 4.5. If you pass, no workers shut down or no BSOD. You can either raise the multiplier or lower the vcore. Keep core temp and cpuz open during that test. Just keep playing with the Vcore and multiplier during those sessions until you find the lowest vcore you can run at the multiplier you want without going over 95. Don't worry, you'll get the hang of it. Post a screenshot of it while prime95 is running. post the screenshot of prime95, CPUz and Coretemp all in 1 screenshot. after setting the bios by that tutorial, set the vcore to manual, the vcore to 1.250 and the multiplier to 45. Save and exit. see if you can boot into windows and run the stress test for 30 minutes. If it runs well, post the screenshot of those 3 programs open. You'll get a lot of help about where to go after the screenshot as well as how to convert back to offset in your bios. If you have questions, just ask. But, always keep a close eye on temps while running the stress test. If they get too high, on Prime95, press file, and stop, yes to the window that will open and the test will stop.
