***The Official Q6600 Overclocking Thread ***

bit of advice i was reading a review on my board and they said that you have to set the
ram+0.3
pcie+0.2
fsb+0.2
mch+0.2
cpu volts1.5
now im stuck on 3.2 with everything on auto,will this do any harm setting it up this way,as im looking to hit 3.4/3.5 if possible cheers,also you can see what my ram is will it go to 2.1 volts cheers

Have you read the sticky in the motherbaord forum?

If not thats a good place to get this all answered! ;)
 
yes tweakinfreak but it says just up the
ram+0.3
fsb+0.1
mch+0.1
cpu volts 1.45
nothing about the others thats why i was wondering if thats why im getting the errors by not going up in +0.2 instead of 0.1 m8
 
sorry m8 didnt take note of the errors just seen it say errors after 18 minutes in prime so came out of it will have to try again,but do you think it will be ok to pump 0.2 instead of the 0.1 m8 and also into the pci-e as well,it was only on 1 core aswell

1.4v

Used BFG 680I 1st Rev, On this cpu and couldnt get anywhere near these speeds, 2.8 was the max becuse of poor fsb on that board.

just got a new board this time EVGA 680I Rev A2
and what a diffrence. ;) im in the 3.6ghz Club ;)

By A2 I presume you mean the A1 revision?

That's what I've got, I just need to cut a few more holes in my case before I start clocking though :P

Nice clock

This is a post I put in the CPU forum, probably should have stuck it here in the first place.

I've had my 680i SLI EVGA board since about 2 weeks before it was officially released (I'm an experienced overclocker having dealt with LN2 and dry ice a lot and used to work for a major review site). Obviously this was an A2 revision board but I was happily running 2gb of Geil 6400 with an E6600 @ 3.4ghz for a good few months.

I recently bought a Q6600 SLACR G0 stepping CPU and promptly realised I needed to get a new revision of the EVGA 680i since mine was an AR model. I bought a new T1 revision yet I'm having major issues with overclocking the Q6600.

I can reach 2.8ghz with 1.35v set in the bios with FSB set to 1.3 and all other voltages at minimum, however I cannot seem to get anything higher than this stable in Windows at all. What's odd is that no matter what voltages/settings I use the system won't fail Prime 95, it simply reboots or blue screens, this is not something I've encountered before when only pushing a few mhz at a time, you'd expect Prime 95 to fail, not a complete lock up.

I'm now running 4gb (2x2gb) OCZ Platinum 6400 @ 5/4/4/15/1T which I have memtested in this system up to 880mhz fine. I'm keeping the RAM at 800 however to try and solve this problem.

Any advice please on what I can do to solve this? Have I just been super unlucky and got a lousy g0 stepping 6600? I'm running a Tagan 1100W PSU so that certainly shouldn't be an issue either.

Q6600
EVGA 680i SLI
2x 8800GTX SLI
4gb OCZ Platinum 6400
X-Fi Elite Pro
2xRaptor 150Gb RAID0
2xSeagate 300Gb 7200.10 RAID0
Tagan 1100W PSU

I've tried running with my old 2gb of Geil to no avail, I'm starting to think it could be the PSU that's at fault but I don't have a spare one lying around that can pump out enough power for my system atm.
 
i dont think its your cpu thats holding you back or your psu or your memory.

its the board...

its all down to the 680i boards you get some clock high some dont, its the luck of the draw simply some have awsome fsb thresholds some dont.

then again last night i got a fright lol
my system auto rebooted just black screened bumped a few more volts into the chipset and presto :)

what ever you do just remember to keep your memory at what you know is flawless and up the chipset voltages 1.3 fsb and cpu to 1.4v and remember to use the p30 bios. mine shipped with this already.

whats weird is my 1000w galaxy psu is showing 11.88v on the 12vline, dam my 2 8800GTxs are bloodsucking leeches.

i dont think i got my psu setup correctly for sli there is a method on these psus so you get maximum 12v+ 300w each and i think i got it setup for 150w+ each lol

anyway its all luck man, for people with p35 boards and what not they dont seem to have issues clocking quads.

its just us sli folks, keep me updated on your progression ;)
 
Already on the P31 bios, plus this board I know is capable of greater than 400fsb since I've done it on my E6600. If it wasn't for the fact that I need SLI to drive this 30" screen, I'd be jumping all over the Intel chipsets right now.

anyone using a Q6600 pref a G0 on a GA-965P-DS3?

i aske due to me not being able to find any info if it is a good combo and this post really got me worried!

http://www.diy-street.com/forum/showthread.php?t=77619

with my dual chip E6300 i can happily run 24/7 stable at 430fsb 3010mhz

but its not enough i demand a quad 3.4+ :D but cant afford a new mobo :/

DS3P here. Don't do it!!! 3.2ghz maximum on water is a joke. Will not take more than 1.375v vcore and just goes into a constant restart cycle. I have tried every possible combination of voltages, fsb and multipliers all with the same result. Popular concensus is the mobo is at fault. It's getting replaced when i decide which to replace it with. Pity really as it got my E4300 all the way to 3.4ghz 24/7 stable.

Its your board that wont do it,

even if your board did 400+fsb with a e6600 then that doesnt even come in to it
my old board did well over 400fsb to get me 3.7+ghz but it wouldnt overclock my quad for **** i could only get 335fsb on my old board.....

and if it wasnt for sli i would be all over the intel chipsets aswell but i seem to have found a great 680 board now that does well over 400fsb... ;) problem is this board has massive vdroop issues lol
 
I know this was true of the early 680's but that is exactly why EVGA released the T1 and A1 revisions of the board. They made physical changes to the board to allow quad core overclocking. Having tested all the 680 boards before they were released I do agree with you that the fsb ceiling is rather random but the rebooting/hard locks don't fit with a mobo/cpu being pushed only slightly beyond what is 100% stable at stock volts.
