blackbyron Posted May 20, 2009 Posted May 20, 2009 Greetings, I'm new to this forum. I have less experience in overclocking. I need help to run E6750 on 3.5 Ghz and when I do a Bless test on Prime95, it failed about 5 seconds. I raised up CPU Voltage to 1.37 and also raised up NB a bit. Then I booted up to windows, open cpu-z and run a stress test, but the problem is cpu-z doesn't show my core voltage is 1.37 underload, instead it showed 1.288 V. what the heck? Can it be because of speedstep causing this? I have IP35-E and Cruical Ballistic 4 GB. Any help would be appreciated it.

Kingfisher Posted May 22, 2009 Posted May 22, 2009 The difference you are seeing in cpu-z voltage compared to BIOS voltage is called v-droop and is common on motherboards. Some newer boards have a BIOS option setting called load line calibration to help correct v-droop. Some folks also have modded their v-droop issue using #2 pencil. I personally don't enable LLC or worry about v-droop , others do. Its a preferance thing. As for your struggle with reaching 3.6 ghz you seem to know what to do but it may be a case where your chip can't. Check your cooling temps and keep playing with your cpu and nb voltages.

maj0rgamer Posted May 22, 2009 Posted May 22, 2009 (edited) have you tried disabling speedstep? this may correct the problem. you should also disable spread spectrum in bios if it's an available option, as it may inhibit overclocking results.

blackbyron Posted May 23, 2009 Posted May 23, 2009 Thanks for the reply, yeah I was about think about disable speedstep. My temps seems fine. But speedstep saves my cpu energy, I'll reply back to you guys if I have it successful Share this post Link to post Share on other sites More sharing options...
blackbyron Posted May 23, 2009 Posted May 23, 2009 (edited) Ok, I can't find spread spectrum, but I disabled speedstep. Then I clocked to 3.60 GHz, played around voltages, but somehow it failed to boot windows and no luck. Right Now I'm running in 3.4 GHz stable. Here are the voltage settings and clock settings: External clock : 425 Mhz Multiplier: 8x DRAM Speed 1:1 DDR2 850 Cpu Core Voltage: stock voltage DDR2 Voltage: 2.05 V CPU VTT: 1.200000V CPU GTLREF 63.0% Northbridge and Southbridge: in stock voltage Hope my explanation looks reasonable Edited May 23, 2009 by blackbyron Share this post Link to post Share on other sites More sharing options...
psycho_terror Posted May 24, 2009 Posted May 24, 2009 Cpu Core Voltage: stock voltage i recently sold my E6750, but it took 1.5v (actual) to get it stable at 3.8ghz. of course every chip is different, but beyond 3.4ghz i started seeing much less overclock per voltage bump.

blooder11181 Posted May 27, 2009 Posted May 27, 2009 try to use vcore 1.40 to 1.50 on q6600 i use 1.5 to get 3.6ghz Share this post Link to post Share on other sites More sharing options...
blackbyron Posted May 27, 2009 Posted May 27, 2009 try to use vcore 1.40 to 1.50on q6600 i use 1.5 to get 3.6ghz Thanks for the reply, what other voltage settings besides Vcore? Northbridge, southbridge ,etc. Also did you disable spread spectrum? I know it depends on the motherboard, but showing me voltage settings really help.

jgv115 Posted June 1, 2009 Posted June 1, 2009 I normally put chipset voltages to auto. (that's just me though) Share this post Link to post Share on other sites More sharing options...
