I followed the Core2Due overclock guide and want to be sure i've got this right before I proceed. Here is my setup:


Intel Core 2 Duo E6600 Conroe 2.4GHz 4M shared L2 Cache LGA 775
ASUS P5B Deluxe/WiFi-AP LGA 775 Intel P965 Express
ARCTIC COOLING Freezer 7 Pro (cpu fan)
Kingston Hyperion PC2 6400 2x1gb (2gb) 800mhz timing: 4-4-4-12 cas: 12
COOLMAX CW-650T EPS12V 650W Aluminum ATX v2.01
Sapphire ATI x1900xt 512mb video card (already own)
Cooler Master Centurion 5 case (already own)

For my board:

AI Tuning: Manual
CPU FREQ: 333
DRAM Freq: DDR2-677mhz (after I changed my timing/cas manually it automatically changed if from 533 to 677)
PCIe Freq: 100
PCI Clock Sync Mode 33.33mhz
Spread Spetrum: Disabled
Memory Voltage: 2.00v
CPU Vcore: 1.4000v
FSB Termination Voltage: 1.4000v
NB Vcore: Auto
SB Vcore (Sata, PCIe): Auto
ICH Chipset Voltage: Auto

C1E: Disabled
Modify Ratio Support: Disabled
Max CPUID value limit: Disabled
CPU TM funtion: Enabled
Execute Disable Bit: Disabled
PECI: Disabled
Speedstep: Disabled

Northbridge chipset config (ram):
DRAM CAS # LAT: 4
DRAM RAS# TO CAS DELAY: 4
DRAM RAS# PRECHARGE: 4
DRAM RAS# ACTIVATE TO PRECHARGE: 12
left the rest alone

CPU Q-Fan control: Disabled

I'm awaiting some responses before I go ahead with the save and reboot to my bios. I'm sure it's right or close to it but wanted to be 100%.

THANKS!

If you have read the guides then why are you asking if its right !

first-off nobody has the time to waste on going over your specs and telling you if you have it write or wrong. every peice of hardware is different even if i had the same setup as you it may work for me but not you so learn to overclock like everybody else and figure it out for yourself! dont be so GD laszy

Whoa.....kinda thought the point of a forum was to get feedback. I thought someone might see something that I hadn't done or something that I need to change. Take a pill.

I have the same set up, although I use a different cooler and OCZ brand memory with the same stats. I recommend skipping the 333-399 range and going straight to 400. Set your CPU multiplier to x8 because x9 (3.6 GHz) is probably too much. DRAM should be 1:1 (i.e. 400 MHz / 800 rating). Who knows what the mobo does with "Auto" voltages, I suggest just using lowest voltage instead. I use lowest voltage for everything, except 2.0 V for RAM (it's rated for 1.9-2.1 anyway) and 1.3125V vCore. I might just have gotten a lucky chip, it being stable at 1.3125V vCore. Try 1.4 first and then drop down as you verify stability.

It's not a big deal, but I have C1E / CPU TM / Speedstep enabled. I figure it might help throttle if my CPU starts burning up or something. Also I left the Execute Bit checking on (not sure if this is called Enabled or Disabled).

For mem I use 4-4-4-12-2-35-3-9-4-10. The last 6 numbers aren't very important at all (probably less than 1% performance boost), and took me a lot of checking and time to reach. I have no idea what numbers your RAM chips will be stable with. I used the memset program to view the memory chips SPD (the default, programmed-in timing values) as a starting point. BTW, you should back off your mem settings to something like 5-5-5-5-15-6-42-11-11-11-11 until you verify CPU stability. Then start tightening memory.

Since my vCore is super low (1.3125 V) and temps are low as well (Core Temp shows 23C idle up to 45C under Orthos testing), I can probably reach 3.6 GHz stably. But I think 400 FSB is some kind of sweet spot because it's exactly where the CPU "strap" changes for this motherboard. Also, I thought 3.2 was a good blend of speed and CPU lifespan. So I left it there.

You could try 401+ x8, or 356 x9, but I wouldn't bother. Above 356 your northbirdge is highly overclocked and 370-399 will get very unstable. (When you reach 400 your motherboard changes the strap and tricks the northbridge into thinking that the CPU freq is a multiple of 333, then the northbridge is only overclocked by (400-333)/333 = 20% instead of (400-266)/266 = 50%. Things get stable again at 400.)

For stability testing, memtest86 and especially its test #5 are good for a quick check of memory settings. Then run Orthos priority 9 with Blended test to stress CPU and RAM. Run it overnight, 8 hours is plenty for verifying stability. (FYI I've never seen it reach 2 hours and then fail, if it fails it will probably do it within about an hour. )

I sometimes then run rthdribl, Orthos, Winamp (playing music), and Windiff (comparing two hard drives) to stress everything. Unfortunately rthdribl consumes a lot of CPU time, dumbing down the Orthos tests.

Ok great I basically have the same setup I knocked down the cpu frequency to 1.375v and during a TAT/orthos test the voltage is stable at 1.32v, my core temps don't go about 54-55 degrees which sounds very acceptable. Nice to knowI can enable C1E / CPU TM / Speedstep if I want to. Thanks for your feedback.

> cpu frequency to 1.375v and during a TAT/orthos test the voltage is stable at 1.32v,

Nice. You have about the same vdroop as me (I use 1.3125V BIOS, and get 1.24 load -1.27V idle according to CPU-Z). If you drop voltage further, your temps will fall. I think despite the low voltage, the low temps might actually make your CPU more stable.

FYI, Rashod0, if your PC powers up but won't boot, then turn the power supply off for a few seconds. Then, when booting up, you can hold down the Insert key the whole time to up with non-overclocked, default settings. This saved me a lot of time when I experimented with overclocking.

Also, I think your mem is better (mine is OCZ 6400 Platinum Rev 2 with 4-4-4-15 timings, not 4-4-4-12). So you might achieve lower settings than me.

Actually thats exactly the trouble i've been having. After I shut off my computer for a while and go to start it initially it will power up but will not boot. (well in a few rare cases it has) but I have to cut the PS and then start up the comptuer and it works. Is this probably because my Vcore voltage is a touch too high?
