What? This Database doesn't contain the glorious Q9650?! Hold up, leme fix that
https://valid.x86.fr/d3bth8

It's all in the CPU/NB GTLs, before tweaking them I had to setup these disastrous voltages vcore 1.4v, PLL 1.6v, VTT 1.44v, NB 1.46v to just pass 10 passes in IBT! I tried every combination you can ever imagine with no help, these voltages otherwise not! I've noticed that I've never touched those GTLs as every guide I've read saying leave this to AUTO but it's the second setting after the vcore it must be important and it's there for something so I decided to read more about those GTLs, actually I've read a lot about it, I haven't understood a single word about it. Hence, I was more convinced of the importance of that thing.

So I bumped my NB GTL from 0.63 to 0.635 and the CPU GTL [0/2], [1/3] from AUTO to 0.640x/0.680x by only doing this magical adjustment I manged to lower my VTT to 1.20v, PLL to 1.50v and NB to 1.26v and vCore to 1.265v look how a small increase have such a large impact in stability!
-that process took me days to be accomplished-

No kidding!? I need to try this for my qx9650. I'm pushing 1.7v PLL and almost 1.6v vcore right now for 4.5GHz.

1.6v vcore on a 45nm chip? is that even legal? You should give the GTLs a try and show this chip some mercy! I hope it's gonna work for you. Do not worry about optimizing your GTLs, but do not go beyond the limits! All technical documents from Intel suggest 0.720x is the limit but also remember that GTLs are derived from FSB Termination voltage so let's say that you set CPU GTL Ref [0/2] to 0.64 and your vFSB is 1.26v then the actual GTL voltage would be 0.64 x 1.26 = 0.8064v for these two pairs of cores what I want to say don't go so high with VTT when your bumping up your GTLs as anadatech has sent their QX9650 to death with 1.5v of VTT so play it safe and don't exceed 1.4v, 1.45v would be your absolute max but I think with some NB/CPU GTLs tweaking you'll managed to greatly lower your VTT!

Back in 2008, the guys in bit-tech.net had an interview with MSI's P45 engineers and they revealed what really does matter when you're overclocking a P45 board and GTLs were on the top of their list and in a related context they were speaking to Asus product managers, they affirmed that just 1.25-1.3V on the northbridge and playing with the CPU VTT and NB/CPU GTL factors can offer a whole more world of performance margins, especially if you are considering DDR3.
Anyway I were talking with a guy in overclock.com forum and he assured me that those GTLs doesn't play a great role in his x48-DQ6 board, he's using a C2D maybe it can't help with these processors but I also figured out that x48 BIOSes got only one option for the CPU GTLs so he can't tweak it separately for each pair of cores just like the P45 Boards (I have CPU GTL Ref [0/2] and CPU GTL Ref [1/3]) that's maybe restricting the overclocking ability of these boards or at least marginalizing the GTLs effect in some cases!

I don't know what mobo you use but if you got this you might want to play with Ai Transaction Booster\"common performance level" I can't post with 10 or lower, 11 isn not stable but 100% stable with 12 I think i can tighten it with more nb voltage so try to loose it when you're tweaking your voltages then put it to the lower stable value. and make sure to set your Ai Clock Twister to light or even lighter I can't stand for 2 passes in IBT with "strong" but it's fine with moderate!

Have a great party with your beast!

Ha thanks I will. 

 

I run an EVGA 790i ftw digital and I've looked at the GTL options sideways for years. Never thought to try them. I've done some research now for my specific board and I think it should knock my voltages way down.

 

Thanks for the info! I've been overclocking core 2s for years and never even thought to try these options.

 

Also pushing 1.6v and capping out at 60C with a modded H100i V2 under heavy stress testing. At stock I wasn't even breaking 40C. I'm hoping with these GTL tweaks I might be able to hit the mystical 5GHz mark.

[rrps700]

Is there anyone updating the document anymore other to the submisssions?

[Steemax]

Got a much better overclock on my new board with my Ryzen 1700x with Corsair vengeance RGB set to 3200mhz with XMP profile.

 

Went from the Gigabyte AX370 K3 Gaming with TT Riing AIO 240 with 3.9ghz at 1.39v. VRM's would get very toasty at 110c. 

 

Switched to ASrock x370 Taichi with EKWB custom loop. 3.9ghz at 1.36v stable with max load temp of 52c. VRM's barley go over 60c now on this new board.

[OzRangers]

i7-7700k + 16GB G Skill Tridenz 3000, and Gigabyte GA-Z170MX Gaming 5

Hello,

Hope you are all doing well, I just got this new hardware, and I have been searching on the internet for a guide that will help me comprehend how to overclocked my i7-7700k on this mobo, I have already updated my bios, and my ram is working at max speed, (enabled XMP) when I fire up the UEFI. I have paired the i7-7700k with a Noctua DH-15. I know that this cooler can keep this CPU cold when overclocked, but I am not sure what would be the best settings to try out?

I have seen people successfully overclock it @4.9 @1.3 Volbt. (I have not tried this myself just yet)

Any advice, or help, or even links that will help me out would be so much appreciated it.

Thanks in advance.

[N3rot0xin]

A suggestion for future form revisions: 

Add a column for case. Cooling capacity is arguably the most important factor when OCing. The ability to intake and exhaust air can drastically affect CPU temps and may inhibbit maximum overclocks even when using the same hardware as someone else.

Some generic oem board too bad don't Overclock that chip. Still works though pretty cool, good backup.

 

[p0is0n122]

I have an Intel core 2 quad q6600 in an Acer oem motherboard that doesn't support bios overclocking and I was this video 

 which shows someone using tape to somehow overclock it and a lot of comments say its real and works, I was wondering if it could potentially melt the tape and ruin the motherboard or what could happen? Most of the comments say it's safe but I would like to be sure

[JR1988]

Well it seems the supermicro z270 benches one of the higher ones...

some playing around with though some still some errors reported going on at 5ghz..trying level 2 LLC...see what that does...so far looks good. 

 

I do like this one though.  A little hotter running out of the 3 tested but nothing major.

 

Overall some well done stuff. 

[Pandelmark]

Hello guys, cause I'm new in this stuff, I heard a guy on YouTube saying that the core i5-8400 with a base frequency of 2.8 GHz which I'm thinking about buying in the near future for a build  despite the fact it has a max turbo boost of 4 GHz, said something  about being locked, so it cannot be actually overclocked, wtf? 

[PineyCreek]

This is kind of hilariously awesome.  I went on LTT about to ask if anyone had done a scenario-based FAQ in terms of different CPUs with explanations of settings, then I found this sticky-thread.  Bless you all

Okay so I have a form all drawn up and in place, and it automatically adds entries to the DB spreadsheet. The form itself is fairly self explanatory, however I would happy to answer any questions that occur. If i missed something that you feel should be added to the form, (hopefully nothing blatantly obvious  :ph34r: ) let me know! I can edit the form and DB at anytime. Also i will be checking the DB spreadsheet to validate entries. If an entry comes through that doesn't match up to the photo, or if the entry comes without a photo it will be flagged yellow. This just means not verified, and it WILL stay in the DB. However if you want this flag removed pm me with your missing photo, etc and I will update your entry and remove the flag :). If you have multiple machines, or CPUs  to swap out with, please add them! Lets make this database huge! Lastly, yes I realize that my entry is not OC'd at all but that was just me testing my form. I'm only on stock atm, so when i actually have the time to tinker with my PC and have money for a cooler i may add another entry

 

 

 Without further adieu here are your two links;

Update 10/16: With a new Cinebench Release I would like to ask all new entries to be measured in that version of release! All old entries are fine, but can be updated if you wish to have a up to date entry :). To update your cinebench score, run the new build (which will be linked in the form) and take a screen cap of it and pm it to me!

Thanks in advance!

Update:

Just in case any of you didn't realize, my new method of letting you know if an entry has been approved or not yet is if the Intel, or AMD spaces have been matched up to the color code. If you notice that some entries haven't, don't worry about it. I'm only human and I will make sure I will update your entries the next chance I can

 

All new Haswell entries will require a main tab of cpu-z and a RAM tab of cpu-z as well. Users that do not include both will be flagged orange in their image link section. Feel free to PM me and I will update your submission if you need it revised!

 

Update 2: Cinebench optional tab created! I would love to see users either update their existing entries by PMing me their scores, and I would love to see all new entries include one! This way we can see how CPUs at given frequencies compete! Link to the Cinebench page is included in the submission form for your convinience

 

Example Screenshot:

 

Something like this is great! Makes my life very easy I'm looking for:

1. CPU Load (shown through something like aida, or just the windows performance tab on the task manager)

2. CPU-Z Open on the main tab (and a CPU-Z RAM tab for Haswell entries)

3. Some sort of temperature monitoring suite

4. A stress test software (aida, prime, intel tuning utility, etc.) Something that records the total time stressed(built in for aida or intel tuning utility), or a way to show me how long the processor was in fact stressed for.

This doesn't work anymore fyi
