Everything is fine thanks, Just been a little busy lately, what about yourself?

I would like to suggest you post how to figure out the offset in your guide. I'm sure that others will benefit from it too. thumb.gif


No problem, glad to be of assistance. Yeah I think you're right, will add it to my guide in a sec smile.gif

EDIT:

Done smile.gif


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 motherboard. LLC = Load line calibration, it's there to help you eliminate or reduce the vdroop as much as possible. Vdroop is the voltage difference between what you set in the BIOS / UEFI and what you really get under load. You will have to work out which works best for YOU. For example, if you set 1.35v in the BIOS and under load during stress testing it's 1.31v and that's HIGH or Level 2 LLC, then you may have to increase the LLC setting to reduce that droop, now depending on how your mobo works it could be like so:

Level 1 being the highest LLC setting 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 for when using Manual voltage, however I personally have found using high LLC with offset is a little better, idle voltage is a little higher (can be helpful in preventing those pesky idle bugs) and voltgea fluctuates a little less when under load.


Then it comes to that task of finding the actual voltage for the overclock. 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:

CPU PLL Overvoltage is only needed when a particular multi (usually the high ones (46x+)) 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 or nearing stability.

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 multiplier and test with prime blend, if it fails, increase the voltage or continue increasing the multiplier until you are satisfied with the temps.

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 thumb.gif


When nearing stability ie. lasting a couple hours or little more in prime blend and it fails, you could try a couple of things like tweaking the PLL and VCCIO (QPI/VTT).

When RAM is at stock (for example, around 1.5v and 1600mhz) increasing the the VCCIO can help general stability when overclocking the cpu, usually between stock and 1.125v. If you're overclocking RAM then increasing it further might help.

PLL voltage between 1.5v - 1.7v could also help.

Just a small reminder, don't think more voltage = more stability doh.gifWhen changing any values in the BIOS / UEFI, start low or stock and work your way up in small increments.

With my current stable settings including the PLL voltage around 1.7v was stable as you can see from my submission to the club. 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.



Here are the additionl info regarding PLL voltage, VCCIO and VCCSA: READ BSOD 124 / IDLE Freezing on Sandy? & THIS (scroll down a little to the *~*IMPORTANT TIPS & FINDINGS*~* section

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


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.


Offset

Once you have 'found' your desired overclock, assuming you have followed the guide above, you should be using manual voltage and the correct level of LLC to determine and eliminate the vdroop as much as possible, then all you do is the following:

Once you know what vcore you require under load, using cpu-z you can work out the offset by using the VID. When running your cpu under load to read vcore, you can do the same to read the VID. That can be achieved by running prime with cpu-z and realtemp. The difference between the load voltage in cpu-z and the VID you see in realtemp is the offset amount you're looking for.

For example if your VID is 1.3875 under load and your cpu-z vcore under load is 1.4275, the offset will be a positive amount from the VID, so it'll be +0.040 (1.3875 + 0.040 = 1.4275)

If the VID is 1.3875 and your cpu-z vcore is lower, say 1.3675, the offset will be a negative value of from the VID, which is -0.020 (1.3875 - 0.020 = 1.3675)

That's all there is to it, if you have issue's with offset like idle / random BSOD's please refer to the many links available in the Stable club or in my Sig.

Hey OP, Not sure if i got missed or if i missed something as proof.

Please let me know if there was anything else you needed.

I had 12+ hours on Prime normal blend

4.4 GHz with custom blend
338

Couple questions though. I have spread spectrum disabled but my bclk is still 99.8 MHz, is that a problem/bad sign? And my bios is set to 1.330 V, but at idle cpu-z says 1.320 V, then drops to 1.312 V during prime95. Is that an issue?

@ TheOctane

You're using the wrong version of Realtemp. Please refer to the rules of the club.


@Molybdenum

I'll add you in a moment, screenshot is perfect. Thank you for contributing to the club thumb.gif


To answer your questions, I've heard that with some MSI mobo's that even disabling spreadspectrum does nothing for the bclk, it may require a BIOS update. the voltage dropping during load is referred to as vdroop which is perfectly normal. LLC controls are there to combat that vdroop as much as possible and keep the voltage under load the same as what you set in the BIOS.

Hope that helps.

I am not one to argue, I will download your specified version and rerun the test but I do want to point out a notable issue:

"REALTEMP 3.67+ ONLY!!"

The "3.67+" is clearly mistakable to mean 3.67 or newer as the other version requirements for software does not require a specific (earlier) version...

The "ONLY" section i perceived to mean that we are only to use CPUZ and REALTEMP as monitoring software as the + at the end would suggest multiple version options.

And the guy you included in the reply to me was using the wrong version as well but gets in? doh.gif

So I am able to boot into windows at 5GHz. It takes 1.46v and my temps are out of control, peak into the 90s. So I guess I won't be able to try to go that high until I get my water cooling set up. I'm so happy with the chip though! I'm happy at the 4.8 I was able to get to. thumb.gif

your first worker failed after 6 1/2 hours and your realtemp is showing 89.5% load...

i think he meant that youre using the wrong version of realtemp - theres realtemp and theres realtemp GT.

Here's my second submission, now up to 4.5. I'll probably sit tight here until I get a better cooling setup of some sort, be it water or better case fans.

Thank you for elaborating. Your reasoning makes more sense. Also since worker 1 stopped... The load would go down.

Time for more Vcore I guess:thumb:
