eXtreme Air Cooling - Build Log + Overclocking

to be fair I am getting pretty damm irritated at the moment! I can prime @ 4.023ghz (on my old settings) temps are reasonable 56/56/53/53 @ 24c ambient... but as soon as I push it any futher it dies within 10 mins..

am running the following for 4.032ghz (people are welcome to comment on settings tweaks):

FSB: 448
Multi: 9
FSB/NB Strap: 333mhz
RAM: is running dog slow (896mhz @ 5-5-5-23, 2.3v) is 2 *1gb OCZ 9600 so am certain its fine
vcore (BIOS) 1.6v
vcore (windows/load): 1.572 (1.536v load is enough for 4.023ghz primestalbe so should be fine for +1 FSB increase)
CPU ref: 0.63
PLL: 1.7v
VTT: 1.5v
NB: 1.55v
NB ref: 0.67
Loadline Calibration Enabled

So the above settings are totally stable @ 447 FSB, but I raise the FSB by even 1 and no matter the vcore increase or board volt increase it is unstable... am just thinking the board is at its max, had exactly the same issues last time I tried to push it more... so i think new motherboard time unless anyone has suggestions

Edit:
Am a little tempted to leave it running for an 8hour run @ 4.023ghz just to prove the above but it is seriously loud not sure I could sleep with it going donwstairs

am going to try a few other settings tonight to see if I can get any joy but following a chat with w3bbo last night (thankyou!) we have come to the conslusion that its the board failing, more than likely power ripples causing instability (only has a 6 phase power regulator thing)... so... P5Q-Deluxe will be on its way shortly, was going to upgrade at any rate so no real issue and my P5K-E will live the rest of its life out as a file server!

fingers crossed its not the CPU failing... just doesnt "feel" like the CPU if that makes any sense?! normally if I have CPU instability then I never get a straight re-boot even if use totally stupid settings for 4.023ghz I get a straight failure on cores rather than a restart.. Also as the restarts are so random anwhere from 5 - 1:45 mins @ past 447FSB for instance I got 1:20mins stable at 4.086ghz last night before it died.. same settings on the reboot and dead within 30 seconds... same settings again lasted 30 mins etc...

Anyways will see if I can get anything more stable tonight... if not new MB it is

New MB on the way :)

Mate, i'm in the exact same position as you at a slightly lower clock. I get into windows at 3.8 but then i get BSOD and restart after 1-2 mins every time. I have throwen tones of volts at it without any luck.

Hope the new board mates a difference. Any reason for picking the P5Q-Deluxe?
 
the p5qdlx should give you a bit more headroom

im really impressed that this is doing as well as it is

i got back of holiday yesterday and the engines on the airoplane made me think of this mod

good times!

It doesnt even BSOD just straight reboot.. which is very odd

Was looking at a max forumla 2 but w3bbo who reviews a load of boards assured me that the deluxe was just as good for less money... so went with that... to be fair I have used a number of P35/X38 boards and have always prefered the Asus ones... also the 16 phase power stuff should provide a bit more stability @ higher FSB so fingers crossed

well had another play around last night and no joy... thought I had fried my CPU at one point when I started a primeload and forgot to turn my fans on... (stupid I know but well after a while you get acustomed to the noise).. anyways after much bricking it the PC finally decided it was going to boot and not spend an age hanging or randomly restarting in the BIOS... anyways no damage done passed a 2 hour prime @ 4.023ghz after that..

New MB should turn up today assumming city link play ball... going to take about 3 hours to swap the boards over and re-mount heatsink and then fans / cable tie it all back together again.. bit of a mamouth task... Just hope the mounting is as good as the current one will make sure I take some photo's as I go and my "secret" tip to mounting the TRU-E :p

looking forward to the updates. but I seriously think you should remove "onAIR!" from your sig - "in an f1 wind tunnel" seems more appropriate :p
 
well new board is in... looks very nice :) OMG the BIOS :D

Clean install of XP is underway... no dout a billion and one things to install from windows update!

More once I am up and running
 
well XP is installed and up to date although windows update was a right PITA... about to flash the BIOS as I am getting some off temp readings... 1c for the socket... cooling is good but not that good... wish me luck!
 
hmm well updated the BIOS no issues :D always a good thing... still getting some very odd CPU socket temp readings....

System is @ stock everything on Auto (I know nub mode):

Idle Temps @ 1.6ghz / 0.96vcore :eek: / Fans @ 6v / 18c ambient
Cores: 17c/19c/17c/17c - verified by speedfan and coretemp
CPU socket: 14c!
Motherboard: 28c
AUX: 26c

Load Temps (Prime95 small ffts) @ 2.4ghz / 1.16vcore / Fans @ 6v (its late) / 18c ambient
Cores: 23c/25c/23c/23c - verified by speedfan and coretemp
CPU socket: 19c
Motherboard: 28c
AUX: 26c

Only thing I can think of in regards to those low CPU temps is I have an outside door open near the rig and maybe its drawing in cold air from the outside as opposed to my temp monitor thats sitting on the desk... socket temp is a real odd one.. some boots it looks way to high like 20c above the cores and others like now its sitting at 12c?! so maybe a duff sensor?

Coretemps look a bit lower than i was expecting but again ambient in here is lower today given that the doors are open so i can nab crafty smokes..

Anyone else had similar issues on Q6600 / P5Q - Deluxe and odd socket temps?
 
anyways as promised some picture candy!

New MB she looks very nice :)

My secret weapon :) a pair of graphite washers... used to use a 2p but found that it got in the way of the screw on the cross support which made mounting the heatsink centrally a right PITA... also the washers are just the right size to force the mounting to push on the edge of the heatsink base which I find gives much more even temps.. not a new idea granted! but well every little helps and certainly a "technological advance" from a 2p! :D

Some nice pics there, im particularly relieved to see that the ocz reaper ram works ok in the p5q deluxe. I bought 4gb (2x2) of the reaper simmilair to yours, but after hearing a few rumours about asus boards and ocz memory, its nice to know that itll work ok in my p5q dlx. Look forward to seeing how you get on with oc'ing this new setup:)
 
In at a overvolted 3.6ghz... just 15mins on prime to make sure that it's semi stable... up with the FSB now until I start to encounter problems.. dont pay much attention to the temps fans at a mere 8v :D
