*Warning/Disclaimer* - Putting silly voltages through your components can kill them. Myself or OcUK carry no responsibility whatsoever for any of your equipment if you decide to follow any of the advice or use any of the settings in this guide.

General Consensus is that max Vcore for a Q6600 on air cooling is aroun 1.5V - 1.55V MAX - PLEASE only push further than this if you absolutely have to and have either water/ phase cooling.

I'm posting this to help out anyone struggling to clock their Q6600 G0 on an Asus Striker II Extreme 790i Ultra board.

There has always been serious slaggings for the Striker boards, especially when it comes to Quad Core CPUs - even more so when filling all four RAM slots on the MOBO.

After a many attempts and crashes half way through stress tests and benchmark runs, I've finally got mine sorted.

I'll update this thread later on with BIOS screenshots and some benchmark screenies.

PLEASE bear in mind that no two CPUs will clock identically - there are no guarantees here - hopefully this will be a good starting point for those who are struggling to clock what is reportedly the hardest board to clock with a quad.

Before we start fiddling with the hardware the software I'm using on my machine is:

Striker II Bios 1104:

Striker II Drivers:

X-Fi Driver:

At least with software & drivers we can rule any problems out there before we start :)

BIOS Settings:

1) - Extreme Tweaker:

2) - Voltages:

Yep :D Its called "Making it have it." :D

42 degrees idle - mid 60's load :D

**EDIT**

Just checked in BIOS and its set to 1.635V.

CPUz is reporting it at 1.68V

Running 4 Sticks of RAM and thats always meant needing more vcore than usual along with the NB.

Congrats on the 4ghz Andy! Run an 8hr prime session and get it into the Q6600 database!

Watch for galvanic corrosion in the NB block. Looks like copper but iirc its actually aluminium.

Strange GTL reference voltages you got going on there! Have you tweaked them to those settings or are they on auto? You might also want to consider using 2T on the memory as it puts less stress on the NB but seeing as the memory clock is so low I don't think it will matter too much.

Nice guide all in all but isn't 'recommending' someone to put near 1.7v through a cpu is a little reckless?
 
Hi Webbo

What settings would you recommend mate?

Not tweaked GTL much - stable in benchmarks but crashed after an hour of orthos this afternoon. 3.9GHZ seems more stable.

To anyone else reading this, webbo knows what he's on about :D

Well the most obvious is to drop the 1T to 2T, memory performance will suffer a little but it will help stabilise your rig and definitely give you more headroom for overclocking your ram.

Setting your VTT above 1.55 will degrade the life of your CPU but if that dosn't scare you too much (which it doesn't looking at your Vcore and PLL lol) then you you should set your GTL ref (gunning transceiver logic) to about 2/3 (66.7%) your VTT and subtract the value from the sum of both intel multi's giving a value of 51.840065 Mv. So in your case +50mv is the nearest you will get on an NVidia board.

For clarity:

1.62v (VTT) x 0.667 = 1.08054v
1.62v (VTT) x 0.635 = 1.0287v
1.08054 - 1.0287v = 0.05184v

For 45nm processors you need to use the 0.635 multi first (resulting in a negative GTL reference) and the 65nm processors the 0.667 multi first resulting in a positive voltage.

Note, this value will need adjusting as you adjust your VTT as both are linked directly to each other.

Intel chipsets make life easier as you can just set the relevent multi and the board does the working out for you.

Intel recommend the following multi's:
65nm = 0.667x
45nm = 0.635x

Hope that clears a little up.


**Edit** just realised you are using 1.6v VTT not 1.62v so your setting should be 51.20031mv (so still +50mv) - just wanted to clarify before the mathematicians jump on my back lol.

Nice one Webbo - more tweaking tomorrow night. Will try dropping Vcore to 1.525V and work from there.

CPU details are as follows if this helps:

Q6600 G0
Product Code: Q6600SLACR
FPO: L720B058
Pack Date: 08/15/07
Version: E10342-001

Told you he knew his stuff folks :D
 
Might have to drop you a pm webbo bout tweaking my quad :) got 4.0ghz out of it but not stable-sure its just one or two settings eluding me!

Nice one on getting to that magical 4ghz though they are some scary volts you were putting through that chip!

Out of interest what is the vid of your chip?
