FAO W3bbo................help!

@3DBULLY.

I've had problems clocking this board. But I dfound it was all down to temps. You are correct that 58 degrees celsius on the NB is where trouble starts. Mine even goes up to 60 before it bsods and reboots.

Also, thought I should mention. Loadline Calibration might cause you instability.

For example, I could run my pc at 3.5ghz (no water yet) for 24 hours prime95. But, I stopped prime, went for a cup of tea, and the pc had restarted. It might not be the case for you, but bear it in mind if you do get instability when it's idling.
 
W3bbo thank's very much for responding to my msg, will go ahead and give your revised setting's ago.

And also check the cpu ceiling out.
Shall report back with details... :)

And everybody else that has given me info.....Thank's also.

You're welcome. Good luck!

Don't forget to report back.

Yeah will do, waiting for some MX-2 and some 3M Tim thermal pads x2(For Power Mosfet's) and a couple of Noctua NF-S12 120mm for my case, as one of the akasa 120mm Ambers seems to be losing speed.

Then shall set about finding the CPU's ceiling.....
Then i shall post back all info for you.

Thank's again.

W3bbo your revised setting's with bios volt's + volts in windows.
What do you think ?
Temps @ idle CPU 27 - SPP 46 - MCP 49 in windows.
Have tried to run this under load but the system freeze's.
Haven't been able to do the cpu ceiling yet, will do that on this coming monday as i work weekends.
Sorry about being slow on the re-post but have been a tad busy.

Backed off the vcore voltage, reads 1.54v in windows...much more stable.

Hey there,

I've got the same board and a Q6600 and have spent the better part of this year working on it.

For a 1600 fsb and RAM linked and synced, my rig needs 1.48-1.50 NB voltage. (2x 2gb of Corsair@ 9-9-9-24-2T). Same RAM as you too.


Also, bear in mind that once you get your rig stable, but you leave it idling for 30-45 minutes and found that it has restarted, that is due to Loadline Calibration.

Some people have no issues with it enabled however, but my board and a few others do have stability issues with it enabled.


Also, keep an eagle eye on NB temperatures. Once it crawls over 58 degrees ceslius it will either freeze or restart.

EDIT - but by reading your post more carefully, I see NB temp is kept in check by you. :D

Yeah i sussed that LLC is a bad thing from the way my OC was behaving, so that was disabled straight away.

I have managed to get 3.6Ghz stable with the ram @ 1600Mhz unlinked at the moment as i'm now shaving off volts from each area as to get the temps down some more but retaining the stability, which is nice.

Also just about to strip the whole thing down again and add a second W/C loop in to do the NB/SB and Power Mosfets as the FUSION block doesn't really cut it, as the temps via the fusion block seem to be to high, even though i cleaned the fusion block's factory paste and applied MX-2 to the NB/SB and also added 2 x 3M thermal pads to the mosfets.
I know this has made the fusion block more effective at transfering heat to the W/C loop by the way that the temps went up.

Idle Volts CPU 1.52 NB 1.42 SB 1.58 VTT 1.38 PLL 1.71
Idle temps CPU 25 SPP 46 MCP 49

Working on getting all the voltages down at the moment.......Work in progress!
 
Nice. Also, do not discount the importance of NB GTL. Sometimes you can get a great OC with it on AUTO. But I have to have a +10mv NB GTL for it to be 100% stable. Not sure why, but hey, if it doesn't crash, I'm happy.
 
Lot of Q6600 owners in here :) I just bought a P5Q Premium from Biffa in the hopes of getting mine past 3.5Ghz (previous owner, Cupra, got 3.9GHz stable). I'm not worried about pumping lots of volts thru it cos i know the 65nm chips can take it ;) was just wondering what max safe temp is 24/7 OC?? Got some OCZ PC8500 and MX-2 on the way :D

TIA and sorry for slight hijack.

I personally let it get up to 70 max on Prime95. Folding@home and such then tend to be 55-60 degrees max 24/7. Wouldn't personally want to go much higher.

At the moment though I'm at 3ghz with stock vcore of 1.3v. So temps max out at 45 during gaming and such.
 
CPU Internal Thermal Control = Disabled

never can understand why peole still turn off the one thing that can save an overheating chip.

It makes no difference to an overclock turned on, and yes I have posted this before.:)

As above really, although I'd guess the fact W3bbo had a Q6600 at 4.1Ghz or similar on water.

Loads of people got 4ghz plus with their Q6600's


w3bbo knows his stuff but there are hundreds more with the same overclocking skills and Knowledge.

Did you try posting in the Q6600 thread I started?

http://forums.overclockers.co.uk/showthread.php?t=17757702&highlight=OFFICIAL+Q6600

Over 2000 people all clocking their Q6600's and sharing advice and tips?


I would post there TBH and have a read.

:eek:Was that a compliment;)

Indirectly yeah, :p

We maybe have fallen out.

But as you know both of us can be professional enough to have enough repect for each other in the overclocking community.;)

You have complimented me on my overclocking skills in the past I have no reason for those sentiments not to be resipricated.
