OC advice with Q6600

[jpacelli]

Finally upgrading my old PC from the following
CASE: Thermaltake III
MOBO: ASUS A8N-SLI Premium 939 NVIDIA nForce4 SLI
CPU: AMD Toledo 4400
PSU: Thermaltake Silent Pure Power W0049RUC ATX12V / EPS12V 680W Power Supply
MEM: CORSAIR XMS 2GB (2 x 1GB) 184-Pin DDR SDRAM DDR 400 (PC 3200)
VID: Geforce 7800Gt 512Mb
HD: 2x250G SATA drives
DVD: 16x DVD Lite-On Burner
CD: 16x CDRW Lite-On Burner
LCD: Samsung 214T 21.3" monitor

I'm keeping the following items
CASE: Thermaltake III
PSU: Thermaltake Silent Pure Power W0049RUC ATX12V / EPS12V 680W Power Supply
HD: 2x250G SATA drives
DVD: 16x DVD Lite-On Burner
CD: 16x CDRW Lite-On Burner
LCD: Samsung 214T 21.3" monitor

Here's what I've purchased for my new system
MOBO: Asus P5N-D nvidia 750i
CPU: Q6600 Retail (G0 Stepping)
MEM: OCZ DDR2 6400 4096Gb (2x2048Gb) SLI Ready
VID: 2 EVGA 8800 GT 512mb
HD: 320Gb Sata3gb

Current OS is Vista 32bit, I'll be installing Vista 64bit onto this new HD

What OC capabilities do I have with this CPU using the stock fan it has?
The Thermaltake Case has 2 rear, 2 side, 2 front and 1 top fan

Also what could I get for the old part's
MOBO: ASUS A8N-SLI Premium 939 NVIDIA nForce4 SLI
CPU: AMD Toledo 4400
MEM: CORSAIR XMS 2GB (2 x 1GB) 184-Pin DDR SDRAM DDR 400 (PC 3200)
VID: Geforce 7800Gt 512Mb

Read thisthis first. Then ask again.

you don't need to read graysky's excellent overclocking thread to know that you'll probably max out at 3.0 or less with stock cooling, even with the excellent case that you have. I maxed out at 3.0 on my Q9450 with stock cooling in an antec 900. If you want to oc you can go "cheap" and get one of the $23 AC freezer 7 pro's in the hot deals forum. That should be good for about 3.3. Or, you can get a true/tuniq/noctua for a chance at 3.6.

As far as what to sell your old components for, just check in fs/ft and see what they're going for right now.

I ebay'd my junk

$140 for A8n32 board with a 4200 x2 chip.
$230 for 4gb of PC4000 RAM
$250 for a pair of 7900GS cards

Actually made enough to put together a nice e8400 system w/8800GTS/g92 card.

Most people are getting around 3.6 on their q6600's, I have two, both will clock that high and stay there, but I run them at stable 3.1 (or so) with stock voltage.

i am building a computer for my brother in law and i have some serious issues with getting thing to stay overclocked. i have an...

Mobo: Asus P5N-D
CPU: Core 2 Quad Q6600 B stepping
Mem: OCZ Reaper 2x2gb 800mhz pc6400 (OCZ2RPR800C44GK)
Vid Card: Evga GTX 260 core 216
Power Sup: Silverstone Zues 650Watt
HDD: Seagate 250gb 16mb 7200rpm

i have attempted to overclock this system before and this isn't my first build, but i am having so many problems with this. i have overclocked it stable to about
2.75 with the memory set at default manufacture speeds. i flashed the bios and now i cant even get the motherboard to retain any kind of overclocking anything that i throw at it. it will restart and go right back to stock settings on all in regards to the CPU's FSB and memory speeds. Just trying to get this computer to my brother-in-law as soon as possible so if someone could help me out it would be greatly appreciated. thanks....

Try this:

1) CLR-CMOS
2) Reset BIOS to known stable over-clock
3) If (1), (2) don't resolve the problem, re-flash BIOS using either EZ-Flash in BIOS setup, or the floppy method
4) If (3) doesn't work or things get worse, order new BIOS PLCC chip from BIOSMan.com


------------------------------
For the OP, jpacelli --

If you can get to 3.0 Ghz within the retail-box voltage for a B3-stepping like mine with an nVidia 680i chipset, you can certainly do it with a G0-stepping and a 750i chipset. Try to contact ASUS to find out which BIOS version works best with the G0, if this was indeed a recent motherboard purchase shipped with a recent BIOS version.

HOWEVER -- I still recommend that you do one or more things, weighing your concerns about such things as "warranty."

1) Lap the processor cap down to bare copper, and use a better TIM -- I personally recommend IC Diamond paste, but others will direct you to AS5 or some of its competitors.

2) Get a better cooler anyway. Any of the most recent ThermalRights will be fine (since May 07); the Sunbeam Tuniq is fine; the OCZ Vendetta 2 is fine; the Noctua NH-U12P is fine -- and there are a few more.

3.0 Ghz is easy for a Q6600 on a 680i nVidia board. 3.15 to 3.2 is not too much trouble (but a lot of stress-testing) with a B3 stepping. My best understanding is that 3.4 Ghz is reasonably possible with a G0. But in the range 3.0 to 3.4 Ghz, I'd get any one of the four or five "best" coolers. Look for Anandtech reviews between May 5, 07 and through this year to present.
