ASUS P5K sure bites for overclocking a Q6600

[Markfw]

I have been through 3 sets of sticks of memory, 3 bios, and a zillion settings. I can;t get it to stay stable at 3.2. Using comparable PSU's (OCZ powerstream 600 that Duvie used on his QX6700) and a fortron 700, both have ninja sythe coolers, both are the same batch cpu's retail. The one in the DS3 popped right in, set it to 8x400 and been stable ever since.

Now the P5K, I have tried everything, and 3.1 isn;t even stable yet.

just wining.....If anybody has a better board, or that board and different memory than I have tried, please chime in.

What cpu stepping is it? I don't think you realize that the Q6600 has a TDP of 110W stock. What did you hope for? I think the best i've seen on air is like 3.4GHZ stable 6 hours.

basically get water or get a g0 stepping cpu

My OTHER identical cpu B3 stepping, on what should be an inferior motherboard, is stable at 3.2. I was expecting at least that out of the P5K, thats my main point here. Identical setups (except memory), and even with PC-8000 that runs all day at 475(in another box), it won;t stay stable at 400 !

Although it is unlikely, did you make sure the CPU wasn't the issue (by swapping it into your DS3 rig)?

 

[Markfw]

nope. That would take hours, and if its stable at 3.1, I can;t imagine that its defective. 6 hours and going... I have made 24 hours yet on any config
Using TAT, the temperature are within a couple of degrees of each other(65c), and per cpuz 1.4, the vcore under load is the same.(1.28-1.20, 1.36 at times on the P5K)

 

[bryanW1995]

is that a p5k ds3 mobo or a 965 ds3?

 

[Don66]

Could just be a dud cpu that can't do what you want.

700Mhz O/C seems pretty decent. (oopps my bad math)

 

[bryanW1995]

yes, and 700 seems even more decent.

Mine won't stay stable past 3.1ghz either, on my P5W-DH deluxe. It will stay orthos stable at 3.2ghz but as soon as I start up folding@home it just reboots, does the same thing in XP and Vista.

 

[Markfw]

That makes me feel better Steve.

To be clear, I have two motherboard with two "matching" chips

a Gigabye DS3 (965p I think chipset) running 3.2 stable for 2 weeks 24/7 65c temps, 1.328 vcore under load.

An ASUS P5K P35 chipset running 3.1 stable(?) for about 11 hours now. It hates Corsair ram, as I just tested that at 400 mhz, when I was getting blue screens at 355x8 I think I even went lower. I know I even tried 333.

The memory that seem stable (ATM) is Crucial Ballistic PC-8000 running 344x9 right now. If this works, I want to put in my 2x 1gb gskill PC-8000,as the crucial is only 2x512.

I feel for you guys. My experiences with this mobo is nothing short of great. Keep in mind that this is my first Intel-system since I had an IBM Aptiva P90 back in the EARLY 90's

I have a C2D E6600, 2x1GB Geil DDR2-800+ Ultra 3-3-3-8, Asus 8800GTS 640M, Asus P5K Deluxe, 2x WD 250GB Sata, 1x Seagate 160GB Sata, Burner + DVDrom, all packed inside of a fully upgraded CM Stacker (the original).


Under jumperfree config, all voltages are set to auto, except for vdimm that I set to 2.3V for reason that will be uncovered Also note that the ambitient temp is about 25 degress celcius.


I first tried using 2x1GB OCZ XTC Platinum PC8000, but these died pretty quick on me. Even below the PC8000 mark and with slack times and default voltage. I've heard that this mobo can kill bad (and good) ram, let's hope my new modules stay longer.
I've set MP to 8, FSB is 425 and memory-timings are 4-4-4-12 with subtimings set to auto.


Now, before you jump the gun and tell me that this is about quadcore, let me share this: The cpu-temp with my old memory peaked @ about 67 degrees celcius. With my new modules, it peakes @ about 59 degrees. I have filled the stacker with 3x 4-in-3 modules, set in extra 3x80mm fans and installed the crossflow fan. I thought you guys might be interested in the different heat-reading with different brands of memory. Could be a pointer


Anywho, I wish you all the best of luck with your setup. I will be investing in a quadcore myself soon, so will be following this thread pretty closely

sorry to hear the troubles man, I was gonna go p5k, but I am now leaning toward the DQ6

Mark
I just put together a q6600 (b3) specs in my sig its running orthos stable for 12 hrs and finished a SMP work unit in like 12 hrs last night.....on a P5K deluxe....I am using the mushkin ddr2 1066 and have had no problems @3.3 temps @ around 50c under load....I have not played with all the settings in the bios but this board seems to like this mushkin ram....hope that helps a little and good luck!
