Smiki007 Posted August 28, 2011 Posted August 28, 2011 Hi to All, could someone tell me what's the best stable BIOS settings (VCore, LLC, RAM voltage, Turbo ON/OFF, C1Eist, etc.), for 4.8 GHz? (my specs in my signature). Thanks. Share this post Link to post Share on other sites More sharing options...

Smiki007 Posted August 28, 2011 Posted August 28, 2011 Check my sig link, that might help you out. Yes i checked:and i have some questions: BIOS Settings (GIGABYTE GA-P67A-UD7-B3): Internal CPU PLL Overvoltage = Enabled Real-Time Ratio Changes in OS = Disabled (Optional) Intel® Turbo Boost Tech. = Disabled CPU Enhanced Halt (C1E) = Disabled C3/C6 State Support = Disabled CPU Thermal Monitor = Disabled CPU EIST Function = Disabled Multi-Steps Load-Line = Level 6, is that a general settings (for any OC higher than 4.0GHz? and this: i7 2600k | GIGABYTE GA-P67A-UD7-B3 | 4.8GHz (48 x 100Mhz) @ 1.455V BIOS; 1.452V - 1.464V CPU-Z | Prime 95 max temps = 69C | Tests Passed,, need to be combined with the firs part, or its all what is needed?

El_Capitan Posted August 28, 2011 Posted August 28, 2011 That's general settings, the Load-Line setting was the best in my experience with that BIOS version (forgot what the BIOS version was). I don't want to give you an exact CPU Voltage setting, as it will depend on the quality of your chip. I have a better chip than the one I tested the Gigabyte board with, so it may be higher or lower voltages. It's just one way to overclock, others prefer to have Turbo Boost Enabled and overclock that way. These are just the settings that I used that worked for me. There's a link I provide that goes to Overclock.Net which will give you more details and different settings you may want to try out.

Smiki007 Posted August 28, 2011 Posted August 28, 2011 (edited) That's general settings, the Load-Line setting was the best in my experience with that BIOS version (forgot what the BIOS version was). I don't want to give you an exact CPU Voltage setting, as it will depend on the quality of your chip. I have a better chip than the one I tested the Gigabyte board with, so it may be higher or lower voltages. So it should be something like this (my BIOS F8): 48x1000 = 4.8GHz VCore = 1.455 LLC = Level 6 Internal CPU PLL Overvoltage = Enabled Real-Time Ratio Changes in OS = Disabled (Optional) Intel® Turbo Boost Tech. = Disabled CPU Enhanced Halt (C1E) = Disabled C3/C6 State Support = Disabled CPU Thermal Monitor = Disabled CPU EIST Function = Disabled all other options on Auto? What about RAM voltage Auto, 1.5V or higher? Edited August 28, 2011 by Smiki007 Share this post Link to post Share on other sites More sharing options...
El_Capitan Posted August 28, 2011 Posted August 28, 2011 Yup, pretty much. If you crash while load testing with Prime95, up the Vcore. If you don't, turn it down a notch and test again. You want the lowest you can go stable so you can keep temperatures down. MJCRO has his overclocked to 5.0GHz, at 1.41V's, but with LLC at Level 8. He's got a monster chip, but then again, his LLC increases his CPU Voltages more during load. Share this post Link to post Share on other sites More sharing options...

You want the lowest you can go stable so you can keep temperatures down. What about RAM voltage: leave it on AUTO, or Stock 1.5V or Higher? Testing with Prime95 (Blend?) 1 hour or more?

El_Capitan Posted August 28, 2011 Posted August 28, 2011 What about RAM voltage: leave it on AUTO, or Stock 1.5V or Higher? Testing with Prime95 (Blend?) 1 hour or more? RAM voltage leave at 1.5V's, 9-9-9-24-2T to start. When you're stable, you can try 9-9-9-24-1T, then tighten the timings and test for stability if you want. Prime95 Blend test for 1 round (about 15 minutes). That will give you a good indication if you're stable or not. If you fail within the first 7 minutes or so, it's your CPU Voltage. If it fails during the last 7 minutes or so, it's your memory. Once you presume to have a good stable overclock, you can test longer for an hour or more, though I take the other approach. I assume it's stable, and if I ever crash while using my system normally, I bump up the Vcore. Otherwise, I'm stable as far as I'm concerned. I'm not one to test on Prime95 for 24 hours (or even an hour at most). Share this post Link to post Share on other sites More sharing options...

Drdeath Posted August 29, 2011 Posted August 29, 2011 Just leave settings alone and enable turbo to see where it takes you. On the Asrock Z68 Extreme 4 it took me to 4.8GHz. Share this post Link to post Share on other sites More sharing options...
Smiki007 Posted September 6, 2011 Posted September 6, 2011 Np, good luck! Here are my results: i7 2600k | GIGABYTE GA-Z68X-UD7-B3 | 4.8GHz (48 x 100Mhz) BIOS Settings (GIGABYTE GA-Z68X-UD7-B3): Internal CPU PLL Overvoltage = Enabled Real-Time Ratio Changes in OS = Disabled Intel® Turbo Boost Tech. = Disabled CPU Enhanced Halt (C1E) = Disabled C3/C6 State Support = Disabled CPU Thermal Monitor = Disabled CPU EIST Function = Disabled Multi Steps Load Line = Level 6 VCore = 1.455V (AIDA64 CPUID reported 1.440V (Full Load 100%) - 1.476V (IDLE)) Prime95 (Blend) 1 hour pass no errors: Max Temps (HW Monitor Pro / RealTemp) CPU = 68C (HW Monitor) Core1 = 70C (RealTemp) Core2 = 79C (RealTemp) Core3 = 79C (RealTemp) Core4 = 76C (RealTemp) Max CPU Power (HW Monitor) = 107.66W LinX 25000 Problem size, 20 Runs, Pass no errors (1 Hour Aprox.) Max Temps (HW Monitor Pro / RealTemp) CPU = 68C (HW Monitor) Core1 = 70C (RealTemp) Core2 = 80C (RealTemp) Core3 = 79C (RealTemp) Core4 = 77C (RealTemp) Max CPU Power (HW Monitor) = 107.80W is these results good for 24/7 or I need to change something?
