Gigabyte Z77 Overclocking Guide

First post to the forum and let me first say it was Tom's excellent Gigabyte OC video and guide that got me here and what a great bunch you all are! Thanks in advance to all. Even if you can't help me with the following problem, you've already been a tremendous help to my first OC adventure!

So here's the problem:

I OC'd by 3570K as per Tom's guide to a 'conservative' 4.3Ghz with temps and Vcore I was comfortable with under a variety of OCCT tests and Prime95. Vcore was stable at 1.224V under constant load and OCCT Linpack (which varies the load) it moved between 1.213 and 1.224.

Installed a EVGA GTX680 GPU yesterday and all hell breaks loose with respect to my Vcore. Vcore under load is now 1.320V (on an idle machine, it's dropping as low as 0.696V). Under the OCCT Linpack test it's also swinging more. Temps and CPU power consumption have risen correspondingly.

Looking at the Vcore swings, it would appear that the Bios is behaving as if the Vcore setting as 'Auto', but it has a set value (1.205V) and Loadline adjustment set to 'Extreme'. (for reference, the GPU settings in the Bios were left at 'auto' when I installed. I did not tinker with any OC settings on the GPU - it's entirely stock with the latest Nvidia driver 320.49 IIRC)

Any idea what's happened and how to fix (aside from yanking out the GPU)?

If my signature setup took, here's my system:
 
Check all the bios settings again mate. Sounds like the CPU specific settings like speedstep are back on?

FYI post the rig specs in you post. Your sig will change but this post will always be here and it may help someone else.

Checked again and see nothing obvious (I changed very little, but if something 'automagically' changed that I hadn't touched or kicked in due to the addition of the GPU, I wouldn't know it...) but I have to admit I don't know what setting(s) you mean when you say 'Speedstep'. What's that?

EDIT: A bit of searching and I found
M.I.T > Advanced Frequency Settings > Advanced CPU Core Features > CPU EIST Function

Mine is set to Auto - always was AFAIK. Would installing a GPU bring this feature to life?

On a whim, I set it to 'disabled' and it makes no difference.

Here's my system:
Intel i5 3570K @ 4.3Ghz / 8GB G.Skill Ripjaws X @ 1866Mhz / Gigabyte Z77X-D3H / EVGA GTX 680 @ 1006/1058 / WD Blue 1TB / Corsair H55 cooler/ Corsair TX750 V2 / Corsair Carbide 300R

Full load doesn't get to turbo frequency

Hello guys!

This is my first post in the forum. I've been following Tom's Youtube channel for a year now and I'm loving all the in-depth reviews and the lengthy but fully informative videos posted.

Some heads-up, I have to say that I'm a complete noob regarding these things. This is the first time in my 7 years owning a PC and first time after a year with my current PC that I dared to tweak BIOS settings, all thanks to Tom and his guide. Also, I would like to inform you, that I'm not a native English speaker, so maybe my posts will have some "akwardness" as well as the above mentioned "noobiness".

Now, my system is the following:
-Intel Core i5 3570K
-Corsair vengeance 2x4GB 1600Mhz
-Gigabyte Z77X-D3H motherboard

I've followed Tom's guide but did not overclock my CPU. I did the first bit, where he tries to find the lowest voltage needed for stock frequency. I wanted to experiment with that first, as I'm planning to buy a watercooler, learn a little more theory and then start adding volts.

My stock CPU Vcore was at 1.15V and i succefully run an OCCT test with Tom's exact reccomended specs and 1.10V and after half an hour the system was stable and the temps where relatively lower than a completely stock test. But i noticed that under full load the CPU would run at 3,603 GHz instead of 3,8 which is the turbo setting that I didn't change.

I changed the DRAM Timing Selectable to QUICK, VCore Loadline Calibration to EXTREME and the Auto settings and System Memory Multiplier and DRAM Voltage to 13.33 and 1.5V.

Is there something I did wrong?

P.S.: i'm now running a test with the CPU Vcore at 1.05 Volts and after 7 minutes in the first test and 15minutes in the second test the test stopped with an "Error Detected" message.
 
Hey Tom, love your work and OC3D for its entertaining reviews :). Not sure if I am posting this right place new to posting in forums part but long time watcher.
My question is when running at stock speeds (3770k H70 Extreme 4) because I am setting the Vcore at a set value I guess it keeps cores running at that Ghz (3.9) all the times is this true and if so is that a plus to add life to cpu due to voltage not jumping up and down the whole time? At auto it jumps from 1.6 Ghz 0.7ish volts to 3.9 Ghz 1.13 volts.

Its probably where youve turned speed step and/or eist off dude.

Could be other things too because I dont know what you have done. All answers are in the video and article.
 
2600K blue screen/freeze when step 3.

Hello!

I am very new to OC'ing so after going trough this guide completely on youtube. I decided to grab my laptop and do this step by step. (it takes more then 1 hour!) :D

Then when trying to boot into windows after changing the very few things I should change, blue screen when going into windows. Sadly I had to do a system restore before, so I did not had bluescreenviewer installed.. But very likely I will get another blue screen later on. I just hope that it will be found by this program since I don't get into windows.

Anyway. so then I went into the bios and hit F7, F10 and got into windows.
Then I decided to do a stress test. Where after about 15mins my pc frooze.
Here is a screenshot off CPU-Z, OCCT, Speccy. What you can't see in Speccy is my PSU and CPU Cooler. Wich are a Corsair TX650 v2. & Sycthe Mugen 3 Rev b.

Hopefully this is enough information thus far, if not feel free to ask me and i'll see what I can do. I saw that you can screenshot the bios too. So if I need to do that, then let me know.

I know that in that screenshot I litterly did 0 steps, I just hit F7 in the bios and went to windows to test because off the crash I had. After reading your comment that I did not follow the guide, wich was sort off correct. At that screenshot I did not followed it. So I grabbed my laptop and did the very few things you told to do. Started a test, after 5mins my pc crashed (black screen) and rebooted. I was like, fine let's try again. Then i tested for about 38mins. Wich it did fine.

But overall I just think I just don't have a stable system.
Here! are the screenshots off that 38mins test.

You need to post screens shots properly.

If you are a complete beginner you should make your own thread :)
 
looking for some help, please!

hey guys, looking for some help!

Yesterday I started following the Gigabyte overclocking video from this website, followed it step by step, for around 30 minutes. I got to the first overclock, and lost all video. then had to reset the bios, video came back but windows wasn't starting up, it was going into start up repair, as always that didn't fix anything. so I had to do a fresh install, which is all set up now.
after installing all drivers I take a look on CPU-Z and the voltage on the CPU is jumping from around 0.970 to 1.200, and core speed is jumping from 1500MHz to 3300MHz, this wasn't happening before I reset the bios.

I'm not really sure why I lost video or the ssd crashed.
any help would be amazing. thanks.
I would love to get this rig up to 4.00GHz

running on...
Intel i5-2500K
not sure what the cooler is called but it's good enough for overclocking
Z77-D3H Mobo
8gb DDR3. 1600MHz
Radeon HD 6950 2gb
OCZ 120GB SSD with AHCI enabled in the bios.

Follow the guide in the video or the article first. (problems you have show you have not)

Like I said, I followed the guide.

I've tried again.
Set the CPU to 1.1 volts and 4GHz then lost video, again!
Could it be the jump from 3.3GHz to 4GHz?

Follow the guide. stop missing steps. Start at the beginning and work your way through. Not being funny dude but Ive done my bit already by making the video etc. Follow that first THEN ask questions because what youre saying above proves you have not.
 
Ok, i've just started getting my overclock set up on my PC (properly this time - last time I just kinda winged it and didn't do it properly), and i've found (I think) at the very least a baseline of what my stock cpu set up is.

I say I think because when I have turbo enabled, i get a BSOD (Turbo kicks it up to 3.8) @ ~15 minutes, and when I run with Turbo disabled, I have perfect stability (2 hour test). This is at 1.1 volts.

This is on the following hardware:
Rampage IV Extreme
3730K 2011 chipset (3.2Ghz out of the box) - stock volts: 1.175
1333 RAM (Corsair Vengence) - set in BIOS using the XMP because I lost the spec sheet and i'm lazy.
Corsair H100i AIO (at the moment - still waiting on my water cooling order to arrive GRRRRR)

So my questions are:

1) Should I accept this as a baseline? Or should I keep Turbo disabled, and keep dropping the volts to get a truer baseline of what my stock speed is?
2) Presuming that I can use this as a baseline, (and recognising that you can't give me numbers here - just looking for some direction) could I just up the volts to the stock (1.175) and keep increasing the multiplier until final stable for a decent 24/7 over clock? Or will this cause further wear and tear to the CPU?
3) On my MB, i've noticed, that when I increase the multiplier on the CPU, the Turbo (which I previously disabled) automagically re-enables and doesn't allow me to turn it off. Does this mean that I should hard input values into the Turbo fields to match the multiplier so that the Turbo doesn't do weird things with the voltage?

any one know lol

i would just like to say hi to everyone and especially hi to tom ive watched the overclocking video numerous times and thought why dont i have a go and i done everything step by step and i underclocked 1st and got down to 1.000v and temps were 49/51/49/48 and ive got up to 4.3ghz at 1.170v temps 63/70/69/65 and it was stable for 9 1/2 hous i think this is good and im happy apart from one thing and wondered if you guys could help when i run any benchmark it says my processor is still 3.4 ghz ???

They take the model number and display its intel specs. It is still running what its set in the bios. Download CPUZ if you have not already and it will show you in there.
