So I got it overlocked as the topic states. Temps are good.

Am I doing it right?

BCLK 100 (default)
CPU Voltage 1.25 Changed!
DDR Voltage 1.5 (default)
VCCSA Voltage 0.925 (default)
CPU PLL Voltatage 1.8 (default)
PCH Voltage 1.05 (default)
CHA CTRL 0.5 (default)
CHB CTRL 0.5 (default)

Cpu Ratio 45x

2600k @ 4.5Ghz with only 1.25v is awesome. (if it's stable)

Yes, you are doing it right.

I would run prime95 for a few hours to check if it is stable. If it is, you are doing it so very right. 4.5 @ 1.25V is amazing.

That's Fantastic!

Factors that affect stability at that multiplier and voltage are, your GPU hardware may require a voltage increase to remain stable gaming, especially an SLI or Crossfire setup.

No listed spec's so we don't know what you're running?

Also the OP/SYS you're running a 64bit OP/SYS requires more voltage to stabilize than a 32bit, so if you've accomplished this overclock with a 64bit OP/SYS out the gate you're in great shape.

Your GPU or GPUs under a 3D gaming load will show you whether or not you're 100% stable, real fast, and if you are 100% stable, Excellent!

How should one run Prime95 to check it for few hours? Im not familiar with running torture test to test the OC.
October 8, 2012 5:20:56 PM

I run Standard succesfully 127.76 seconds with max temperature of 70 C.
October 8, 2012 5:50:54 PM

Now I run InterBurnTest again with High and it was also succes. Im taking that I have stable clocks and awesome ship by running it with such low vCore.

I'm jelly..
I run @ 1.3V on my 2550K @ 4.4GHz..

run some prime and then game some and report back..

I forgot to mention that I have Hyper Threading off. I have had it off since then when I heard that while its on it causes mini stuttering in Battlefield 3, and turning it off really fixed that problem - dont know why. That might be one reason why vCore can be so low. But other word is, that I have no idea what Im talking about since I have how hyper threading works and if turning off HT has any effect on vCore.
October 8, 2012 8:06:10 PM

yes.
with hyper-threading enabled it does utilize more voltage/power but also heard it makes minimal difference in gaming. sometimes detriment, I couldn't say.
you do realize your basically running an i5-2500K if you have H-T disabled.
nothing wrong with that and I guess if not gaming and need the H-T for heavier threaded task then just go into BIOS and re-enable.
October 8, 2012 8:06:53 PM

Note to self: Always read what you have written after you write msg.

*I have no idea what Im talking about, since I dont know how HT works, or if turning off HT has any effect on how well the CPU overclocks with lower vcore.

Sorry trying to fix what I just typed, to reduce confusion. I hope this clears things a bit.
I wish the edit would work, but cant complain, we have awesome forums and plenty of helpful user here always helping each other out. Thanks all for the help on stress testing the overclock and with my question. Now Im off to play some games, and I might post back here if anything goes wrong. I run all the Prime tests for about 10 minutes or what ever their duration is at default, I imagine the OC is stable and I will not have problems with it.
October 8, 2012 8:13:44 PM

good-luck and keep us posted.
I've been gone from forums for some time and recently got back into it for a bit.

go game..

I actually never tought it about like that, maybe it was quite fool of me to spend extra 100 € on cpu instead of investing it on graphic card. Im not even using the intel HD Graphics either since its garbage and Lucid Virtu Mvp actually reduces graphical quality (no wonder it increases fps in games, duh :pfff:  ) There is however larger L3 cache than in 2500k, but Im not actually very sure if thats actually any real use in gaming. Im not doing any 3D Max or 3D stuff, not even video encoding so its not actually benefiting me that much. Next plan in future for upgrading something from the computer is graphic card, possible Asus GTX 670 DirectCU II Top seems to be a real winner, however 680 is also very tempting even tho 680 is not having the best "performance per dollar spend" ration.
October 8, 2012 8:59:33 PM

You're as lucky as I am. I'm running my i5 3570 @4.5K with just 1.25v. I added the .05 for assurance even though it ran fine @1.20/4.5GHz. For GPU, I'd get a 7970 GHz Ed. My Asus GTX670 DCUII is awesome for it to 1200/6700 but I lost the settings so I settled at 1140/6400 and issues and still amazingly quiet. So I'd get that or Sapphire/Gigabyte 7970 GHz Ed. All the best.

One thing I noticed right now is that CPU-Z and Asus Sensor are giving me different setting than what I set the vCore in bios. CPU-Z Tells me the vCore being 1.272 and Asus tools tells me its 1.278. I think it doesnt matter that much what these tell me since the Asus TurboV Evo tool tells me that the vCore is exactly set to same as its in the bios. Also what I remember is that some of the stuff allows the vcore to change a bit because of something moving range thing or so, cant remember it right now.
Im still safely in the "green zone" so nothing new to report here right now.

As has been said, if it's stable, you're doing it right.
October 8, 2012 9:42:58 PM

me personally would have gone 2500K/3570K and higher end GPU than a 2600K/3770K and lower level GPU.
but to each his own.
keep the 2600K and next upgrade is a better GPU than the 5770 your on.
got all the goods like SSD and RAM set to 1600MHz.?

Yep. Oh and going over 1600MHz doesnt seem to have "major" difference considering money spend.
Got SSD but the 60GB runs out fast, 64-bit windows 7 takes 28 GB so not that much for games T_T
Will go for bigger ssd after getting new graphcs and 120hz monitor to go along with it.
October 9, 2012 1:46:15 AM

I run my games off a WD VelociRaptor 10K HDD and not off SSD.
I use the SSD for only the OS and important apps.
have you looked at just caching your current HDD and it's OS install.?

120Hz monitors are expensive.

It takes more voltage to stably overclock when hyper threading is enabled, that's why you're getting away with such low voltage and why you experience game stutter while using hyper threading, it just flat out has to have enough voltage to operate properly with hyper threading enabled.

My 2700K with hyper threading enabled hasn't stuttered the first time in any game I've played, of course my voltage is not as low as yours either.

I would suggest since you own a 2600K to revisit overclocking from scratch with hyper threading enabled, but it's your setup, your money and your prerogative as to how you do what you do!

It was stuttering on stock settings while HT was on.

how much RAM do you have, at least 8GB.?

Battlefield 3 is 32-bit game so my memory (2x4gb @ 1600Mhz) shouldnt be any problem at all.

Hey guys, its me again, Running 4.4 Ghz @ 1.265 vCore, with threads on and everything, its running fine so far. Asus own monitoring program says its 1.29 Vcore actual and so. Seems to be working fine.
