Foruman Posted January 10, 2012 Posted January 10, 2012 Hello All! I am fairly new to overclocking, and just have a few questions. First of all, I achieved a stable overclock of 4.5GHz using the settings listed below, but I was wondering if there's another way to set the voltages either using offset or manual mode. The reason is, I followed several guides to set these settings, and am not sure if they are the best for overclocking. Also, when the system idles, the frequency and voltage never decreases. I know that it's supposed to be 1.6GHz @ 1.0v when idling, but my computer is always 4.5GHz @ 1.336v. Another thing, when playing games and running other CPU-intensive software, the voltage decreases to 1.296v, and sometimes causes a BSOD. The only BSOD error code I get is 0x124, which means too little Vcore. Can someone help me out and let me know what settings I have that are incorrect/not optimized for the overclock I have applied? I have a good aftermarket air cooler, so the temps are 24C when idle and ~50C when under load. Thanks all!

Tjj226_Angel Posted January 10, 2012 Posted January 10, 2012 Turn off Speed Step, Turbo mode, and load line calibration to see if you can bump up the multiplier. Otherwise it looks good. Share this post Link to post Share on other sites More sharing options...
Foruman Posted January 11, 2012 Posted January 11, 2012 Turn off Speed Step, Turbo mode, and load line calibration to see if you can bump up the multiplier. Otherwise it looks good. So if I turn these settings off, I should be able to see a decrease in the CPU's frequency and voltage when the system idles? Also, the lowest LLC setting is Regular (0%), so I believe this means the same as "OFF?" Do you recommend using offset voltage or manual voltage? I am a bit confused about offset voltage, because I see some website recommends as much as +0.100v, while others recommend -0.015, the setting that I have now. How does it work, exactly? Also, if I do try to raise the multiplier, then what adjustments do I have to make to my voltages? My main goal is to only get 4.5GHz, but with lower voltage, such as 1.300v. But, I think my chip needs 1.336-1.344v, is that still considered good for 4.5GHz, or do you recommend stepping up the multiplier as well with that voltage? By the way, I tried and was successfully able to boot into Windows with 5.0GHz @ 1.4v, but it is very unstable and may crash at any time. Does this mean my chip is capable of 50x with the right voltage settings or not? Not that I want to OC it to 5.0GHz for a 24/7 build, but just curious.

Kingfisher Posted January 11, 2012 Posted January 11, 2012 You have a nice set of hardware! Welcome to the forums. What I like to tell all the new folks is every pc is different , kind of like people. Therefore each pix will overclock differently. The best advice I can give you is keep at it, read up on guides and stickies. Look for others with similar hardware and see what they have come up with. Without sitting at your pc it isn't easy to kelp overclock it. That's where you come in . The best way to know if your stable is stress test it with the various programs out there prime 95, occt, ibt etc. Any blue screen is a sign you are not stable. Have you tested yor RAM? Sometimes you may be CPU stable but your ram isn't. Or vice versa Don't get discouraged. Enjoy it , overclocking is a blast. Good luck!

Wait...you are already at 4.5 ghz and you have very good temps. Why would you want to lower the voltages? Not to mention that I bet you could do a 24/7 5ghz with about 1.43-1.45 volts.

scr4wl Posted January 11, 2012 Posted January 11, 2012 Not to mention that I bet you could do a 24/7 5ghz with about 1.43-1.45 volts. I wouldn't be to sure of that. A lot of these more recent 2500ks are hitting walls at 48x and 49x multis. Even with internal PLL overvoltage enabled. With that being said if your temps are ok and your OC is stable definitely push the chip further. EDIT: Nevermind didn't see that the OP was able to boot at a 50 multi. With the right voltage you will be able to get it stable. This could take a fair amount of voltage though, so you might not be able to do it with good temps.

Drdeath Posted January 11, 2012 Posted January 11, 2012 2500K's as long as you have a decent chip do 5GHz. I pulled 5Ghz on a Z68 Fatal1ty review... http://www.pureoverclock.com/review.php?id=1344&page=10 Encouraged, we did some manual tweaking by opening F-Stream tuning, increased the vcore and CPU/PLL voltage and ultimately hit 5GHz which was stable for 6 hrs Prime95 before we stopped the Torture Test.

Waco Posted January 11, 2012 Posted January 11, 2012 Turn off Speed Step, Turbo mode, and load line calibration to see if you can bump up the multiplier. Why would you ever want to disable any of those? Share this post Link to post Share on other sites More sharing options...
Foruman Posted January 11, 2012 Posted January 11, 2012 (edited) Thanks everyone for your replies! Why would you ever want to disable any of those? So now I am confused. I agree with Waco and think that these settings should be enabled in order to save power and the life of the CPU when it is not in use. However, my CPU is always at 4.5GHz and 1.336v no matter what, and when I play games like Battlefield 3, the Vcore sometimes drops to 1.296v, and that's when the occasional BSOD 0x124 comes in. Do you guys know how to resolve these problems? Wait...you are already at 4.5 ghz and you have very good temps. Why would you want to lower the voltages? Not to mention that I bet you could do a 24/7 5ghz with about 1.43-1.45 volts. Alright, so the temps are good. I am a little bit confused because some people and guides say to lower voltages as much as possible to keep the temps as low as possible. I realize that every chip is different and I can't expect mine to achieve what someone else's did. However, I have this question then. If the temps are good, does that mean I should not attempt to find a way to get a stable 4.5GHz OC at 1.300v? I seem to have the impression that most people can do this, and so that's why I ask is it normal/good that my CPU needs 1.336-1.344v to maintain a stable OC at 4.5GHz when everyone else seems to need only 1.300v. Is lower volts or higher volts better? I just want this cleared up so I can have a better understanding when overclocking in the future. You have a nice set of hardware! Welcome to the forums. What I like to tell all the new folks is every pc is different , kind of like people. Therefore each pix will overclock differently.

Sometimes you may be CPU stable but your ram isn't. Or vice versa Don't get discouraged. Enjoy it , overclocking is a blast. Good luck! Thanks man! I don't believe I have tested my RAM yet. They are brand new, just bought about a month ago. I use them at stock speeds no problem, but if I just change just one timing, like from 9-9-9-24 to 8 in place of any one of the 9's, then the system won't boot at all, and upon restart, the BIOS tells me that the overclock settings failed. Does this mean that I have faulty RAM, or do they simply not OC very well? I believe my Vcore is plenty enough since some people can do 4.5GHz @ 1.300v, so maybe the 0x124 BSOD is coming from the RAM, as you said. Thanks again, all!

Foruman Posted January 11, 2012 Posted January 11, 2012 (edited) Also, do my settings look alright? Do you guys recommend using offset or manual voltage for the Vcore? I'm not so sure how to use it, like what the offsign sign and voltage does. I read on some guides that it adds/subtracts voltage according to some motherboard command, but I can't figure that out, especially because the operating Vcore changes when changing the LLC setting. For example, I remember setting LLC to Extreme once with offset (Auto) voltage, and that brought the Vcore to 1.4v in Windows! That's way too much for 4.5GHz! So I followed some other guide and they recommended -0.015 offset voltage with LLC set on Auto, which I think is actually Ultra High, since both settings seem to keep the Vcore the same. I don't know, what do you guys say about this? Edited January 11, 2012 by Foruman Share this post Link to post Share on other sites More sharing options...
