Those were before from my original post. So some are changed now.
lol and what changes have you made exactly?

Currently I am at 4.2GHz with auto vcore. I made the load line calibration level 2. I changed the memory to 1600 since that is what its supposed to be at. (It's not on profile 1, but auto.) Other than that, its all the same. Also, I did some testing and it seems that when I have level 2 enabled I can only go up to 42x without it freezing on me. Maybe level 2 doesn't allow for 1GHz overclock?

Okay well clearly you didn't read the OP, but not to worry i'll post it here for you again.

try this:



Here's my quick little sandy guide:

Quote:
The only things will that will require multiple changes are the vccio (VTT), PLL voltage and vcore, refer to this:

Set the whole thing to stock and start again. This time only change the RAM to XMP (STOCK) and run prime blend for a few mintues to see that your CPU is functioning properly.

Then comes the task of determining the voltage for the multiplier, but that comes after you find the correct LLC setting for your mobo. What you want to do is set the LLC to the one that is closet to what you set it to when the cpu is under load, so for example if you set 1.35v and under load it's 1.31v and that's level 3 then you may have to increase the LLC, now depending on high your mobo works it could like so: 1 being the highest LLC and 5 being the lowest and vice versa. The objective is to keep the voltage under load as controllable as possible without it letting it spike. These LLC settings will be different amongst mobo's. For Asus mobo's the Ultra high (75%) LLC seems to work best.


Then it comes to that task of finding the actual voltage for the overclock, however before we get to that, I would advise you to reduce PLL voltage to 1.7v [B] (Scroll down or go to sandy stable club about PLL info). Then set the vcore manually to 1.25v, Leave C1E and Speedsteep enabled and run C3 and C6 on Auto if you can, if not leave them enabled. Also leave Spread spectrum enabled, if you find that it disrupts the bclk in cpu-z then just disable it.

Additional settings that you need to change from the get go, but won't need to be changed afterwards:


Can be found under advanced settings/cpu configuration:

Overvoltage is only needed when a particular multi (usually the high ones) doesn't boot into windows.

This should be a stepping stone to get your rig stable. With those settings you will eventually get to the point where you're stable.

Set the multi to 45 and the vcore to 1.25v and increase the vcore each time after you stress test, run a quick custom prime with these FFTs (1344 & 1792) like THIS and go back and change the vcore accordingly, bump it by one not big jumps and that goes for PLL and VCCIO (VTT) and VCORE!!!

Work your way up from there, increase multi, test with prime, if it fails up vcore, if not up the multi. Until you are satisfied with the temps and it is stable then continue upping the vcore to stabalise.


Just a note: The custom FFT's are not that consistant, making them not all that reliable, however if it works for you, then that's great. What I mean by inconsistant, is that it may pass once with the same settings but may fail the exact same run second time round. In that instance I will recommend you to run a standard blend test to find your overclock, using intervals of 15/30mins. This duration will increase when you're nearing stability. This is a lenthy process, one that takes time and patience, make sure your up to the task

Head over to the Sandy Stable Club for more info and tips


Here are the additionl info regarding PLL voltage, VCCIO and VCCSA: READ THIS & THIS

For the last 10days or so I tried messing around with the PLL, I dropped it down to 1.4v and started going up, I kept on receiving the Error 124 up until I reached 1.55v and it passed both the 1344 and 1792 test along with a few hours of prime blend. My sweet spot is at 1.55v.


One more thing, BSOD Error code 101 is usually refered to the vcore being too low, Error 124 can also be vcore, VTT (VCCIO) or even PLL voltage being to high or too low.

I set the multiplier to 45, vcore to 1.25v and it wouldn't boot. Lowered the multi to 42, vcore to 1.34v, and still nothing. I don't know what I am doing wrong. It seems that my chip needs a high voltage for even 4.2GHz.

when you did that what other things did you change?

Just change ram to profile 1, pll voltage to 1.7v, and configure the turbo boost power for the asrock mobos.

When I set it back to stock and run windows, I get a black screen and a blinking cursor now. ughh.. now I have to figure out how to fix this.

did you try enabling CPU PLL overvoltage at that point?

No I did not, but I put back in my windows 7 cd, and clicked repair. It said the repair could not detect the problem or something, but I'M IN! I seriously got scared there. And for the overclocking part, I think I'm just going to stay at 4.2GHz with auto vcore and level 2 llc.

Edit: When my 2500k is under load it goes to 4.2GHz and uses up to 1.36v. Is that normal at all for it to be using that much power? Or do I just have a stubborn chip? And at idle it clocks at 1.6GHz and uses 0.95v.

Hi all,

I am looking for help on getting my new rig stable, here are my latest settings.

Hopefully you can look through these MIT bios screens and give me some suggestions on what to change.....

I am not sure what some of these options in the bios do, if someone could elaborate, that would be great.

Thanks in advance,

Hogans.

I just stopped a 10h40min blend because taskmanager said only 0.99GB ram was in use

well 1.35V is fine for 4.5GHz, and LLC lvl5 is required to keep it their under load, right now in win7 HWmonitor says its idling at 1.37, while in P95 it was steady at 1.36V

but I''l have to do it all over with much more ram to test the required extra ram voltage for 6-8-6-20-24-1T

tthhen I want to compare CL6 @ 1600MHz vs CL7 at 1866 if that speed will even work

and EXCELLENT temps from my silver arrow, set on "normal" in the bios, max was 53-61-61-58, and I still could barely hear it at all
