Hi guys :smile:So, I got Windows installed (of course!) and everything is set. At the stock 3.3GHz, I'm already seeing a MASSIVE performance increase in FSX.... I can FINALLY do a flight with real world weather, without the REX clouds dropping my frame rate.... At cruse, I get 50FPS+!!!!! I'm so happy with my current performance.HOWEVER...I want more.Yes, you heard right. I want MORE performance.Obviously, I didn't buy a 2500k for nothing. (or a Hyper 212+ for that matter) So, does anyone know some newbie guides on the internet that I could use to help me OC this thing? I'm looking at a safe 4.2GHz, maybe if I could a 4.5GHz. Like I said before (or did I?), I'm a newbie to this stuff (OK, I'm not THAT dumb. I know some terms.). Do you have any tips/advice that you can give me? I'd appreciate it. Now if you'd excuse me.... It will be 2012 in 2 hours. :Party:

This was written to me from Dario IreberriVery helpful IMO.This is how I go about OCing:1.- Test on stock clocks. Make sure it's all stable, temps are fine, see what's the stock Vcore (VID) to have an idea of what to expect from the chipShould run on stock clocks for a week or so and pass a few hours of Prime95, OCCT or the likes2.- Decide what Vcore you are ready to push. For SB, 1.375V is my max.3.- Downclock your RAM. This is to get RAM out of the stability equation. Setting it to 1333 CL10 or something like that will ensure RAM doesn't interfere with your CPU overclock, and that you'll be certain when you hit the chip's limit it will be the CPU limit, not the RAM crapping out. This is more of a legacy thing since older platforms overclocked with BCLK and that has a bigger effect on RAM, but I still do it with SB5.- Set a manual / fixed Vcore and multi to reasonable value to start testing. Something like 1.35V and 4.4GHz for example4.- Get to know your board's Vdrop / Vdroop and Load Line Calibration habilities. What you want here is to get those 1.35V you set in BIOS in Windows.Vdrop will lower your Vcore in Windows so while idle it will be something like 1.34V. Vdroop will further drop your Vcore at full load, maybe 1.33 or 1.32VStart upping LLC till you get exactly or as close as possible those 1.35V you set in your BIOS at full load and idle in Windows. Monitor temps while you stress test and don't let it go over 80ºC5.- Once Vdrop & Vdroop are cancelled, set your Vcore to your maximum, 1.375V for example using manual Vcore in BIOS. Check again you have no Vdrop & Vdroop by booting into Windows and stress testing for a short stint. Monitor temps while you stress test and don't let it go over 80ºC. You should now have 1.375V at full load and idle too (to check idle Vcore you wil need to switch off power saving modes, Speedstep, C1E, C3, C6 report)6.- Now that you have your maximum Vcore in place, start bumping your multi 100MHz at a time, and stress test thoroughly. Repeat until you hit the chip's limit. Monitor temps as you increase the frequency!7.- Once you know what frequency your chip can take, start lowering your Vcore till you find the minimum it will run at you max overclock8.- If you want to use the power saving modes, you'll need to switch from manual to offset Vcore modeHere's how to obtain the offset value to get the Vcore at which your OC was stable in the previous steps (in manual mode)this are the approximate values for each LLC level. I believe this table was made at 4.6GHz. Not sure thoughSo for example, if you want 1.35V and your LLC is set to Ultra High, set your offset to -0.010.Boot into windows and open CPU-Z. Stress test for a minute to see what full load Vcore you have and see if your Vcore is where you want it to. Lower? raise it in BIOS and try again. Higher? lower it in BIOS.Once you have your offset, you can enable C1E and EIST. Check if it throttles down to 1.6GHz and 0.9 - 1V while idle, and stress test again for 8+hours. Monitor temps and Vcore while you do9.- You now have (hopefully) a rock solid CPU overclock, time to focus on memory speed.Set your RAM speed, timings and voltage at what your sticks are rated and stress test for 8+hours. Monitor temps and Vcore while you doIf you want to overclock your memory, do so, and stress test for 8+hours. Monitor temps and Vcore while you do

Thanks Ben. I'll look more into that.

Thanks Ben. I'll look more into that.

Or you can bump your multiplier to 48, set CPU PLL overvoltage to enabled, put CPU vcore @ 1.38, put Load Line Calibration to Ultra High, and you might be stable.

Please go step by step not just boosting it to max without prior knowledge how your CPU sink is doing. Ben is again doing it :Praying:

Now seriously, come on Srdan.1.38 volts isn't going to hurt anything.

Probably not. I am just careful, that's all. I burned a CPU couple of years ago because I just "set the vcore". But it was an old pentium, those were easier to burn than todays thermally protected CPUs...

Exactly...And I have done quite extensive research on voltages on the SB lineup. Don't think that I am some druken idiot typing in unsafe numbers into my BIOS.I am extremely careful. If I were to fry this chip, I wouldn't have a computer for quite a while. LOLBut seriously, how did you fry your Pentium?? lol

Seriously, you think I remember voltages I have set on a CPU 7 years ago? I think it was 2003 or 2004... I think it was just before I have gotten my first C2D. I tried to sneak a bit more out of a Pentium, I think that was the time of my first 3GHz... possibly... so I played a bit with it, and set some things from forums... voila :Hypnotized:

Seriously gross.

Don't think that I am some druken idiot typing in unsafe numbers into my BIOS.

I don't think you are one, au contraire. With your setup I hope you are not.But in the end of the day, people might understand it differently, and if not being careful do something wrong or upside down and then that's it.I learned to be extra careful on forums, since giving advice to someone else about overclocking who has less experience is like giving advices about driving to the person without the driving license... get my analogy?

Totally understand what you are saying. I was simply trying to be helpful. Those numbers I gave him are nowhere near high enough to fry his chip.

Alright...

WELL ANYWAY...I was directed here by a user. So tell me guys, me BIOS looks like this:He told me to:"Set Internal PLL overvoltage to Enabled. Extreme Memory Profile(X.M.P.) should be set to enabled. What RAM do you have?Spread Spectrum needs to be DISABLED. Set your CPU core voltage to 1.3."Can anyone tell me what does settings do? (Except for the CPU core voltage, I know that)Also, how do you test with Prime95? I downloaded it and extracted it but when I open it, it has this popup asking me to do something.

Anyone?!?!

'ADJUST CPU RATIO' is where you set the overclock speed.you cpu freq is 100.therefore x33 is 3300 Mhz.if you set 45 for the ratio you have 4500 Mhz.(don't do that all at once, of course)The step by step method, testing each step using the utility before going to the next step, is the safe way to proceed.first up the cpu core voltage to 1.35.set the ratio forward 1 at a time 34,35,36,... 46.Test after each step, about 15 minutes for the first steps.As you get to 40 and above test longer each step, an hour!A long test but its the safe way.I would not go over 46 without a more exacting procedure tutorial and understanding the tutorial.The test = running a recognized overclocking test utility and studying the result of the test, each step.1.375 voltage is where I ended up, after first starting with 1.35 to do the step by step tests.http://www.clunk.org...-beginners.html
