Intel Core2Duo Conroe Overclocking thread: post your results and questions

Ideally your should mention your Core2Duo/Quad CPU, Vcore, Cooling system, Motherboard (and BIOS), RAM and actual speed, and Stability method. Also some screenshots would be nice.

So lets show yours! :wink:

Questions are also welcome!

This settings are still not optimal yet…

~24+ hours Folding@Home stable – 97-99% load but I don’t feel wasting time on Orthos. :wink:

Nice zevia :slight_smile: you lucky dog :clap:

Nice one Zevia :clap:

Edit: Are you trying to make jwill cry? :bigsmile:

You mean showing 5 minutes per frame folding project 3025 above? :bigsmile:

Yes. :bigsmile:

Seriously though, those are some nice results. I haven’t OC’ed in ages, and even then not with an Intel machine. :slight_smile:

Hi :slight_smile:
Why overclock? Just get a Quad. :stuck_out_tongue:
W/C PC means my CPU temp is a constant 42 degrees. :iagree:

Because we have learned how to OverSpeed and OverBurn dvd media? :stuck_out_tongue:

Well (kind of) seriously, it’s a Conroe, born to overclock. :cool:

Just get a Quad. :stuck_out_tongue:

That would be Q3-2007 when the Q6600 hits $260ish. :smiley:

Motherboard: Asus P5W DH Deluxe
BIOS: 1707

CPU: Core 2 Duo E6600
OC Speed: 3.5GHz
FSB: 390MHz
CPU Temp: (no load) 23C
CPU Temp: (partial load) 39C
CPU Temp: (full load) around 52C
Cooling: Artec Cooling Freezer 7 Pro (runs very quiet)

RAM: OCZ OCZ2P800R21G (2GIG matched pair)
Speed: Controlled by SPD (Aggressive timing makes little difference IMO)
Voltage: 2.10 volts

The CPU will run at 3.6GHz, but runs too hot for my liking. :slight_smile:

Stability: Everyday use for around 10 weeks (variable CPU loads).

Dee …what are your ambients temps if your cpu is idling at 23C

OK…typo …idling at 31/32 not 23C

my ambient temp is typically 23-25C

Room temp is around 18c ATM.
System temp as you can see from the screenshots are around 31C - 32C.

Well nothing special here except my degree of stability?

Hi zevia; I am TCAS son:

I’m trying to overclock my cpu and looking for some help. Here are my system specs:

Asus P5B Deluxe WiFi
Kingston Hyper X PC6400
eVGA 7900 GTO
Zalman cooler 9700 LED

I’ve seen guides before showing BIOS screens however I don’t understand what they mean. I’m looking for an easy step by step guide geared more towards newcomers. Thank you very much.

check here:…excellent forum for help

if I owned the mobo I would help you but I have a Badaxe2

Motherboard: Asus P5W DH Deluxe, BIOS 2004 (Beta)
Cooling: Zalman 9500 AT
CPU: E6600 2.400 Mhz
Batch: L631B120
OC: 3,700 Mhz (412x9)
VCore: 1.4750V
PCI clock freq: 33.33 Mhz
MCH: 1.75v
ICH: 1.05v
RAM: Mushkin XP2-8500 Xtreme performance 2Gb (Micron D9)
Actual Speed/Latency: 824Mhz 4-3-4-10-2T
Voltage: 2.25v

This is just to show the chip is capable. Way too hot for me to let Orthos stay running. Asus probe temps don’t look bad but Core temp was hovering around 70-72 deg while running these tests.:disagree: For stability I have been running @400x9 (3600 Mhz/Core temp 52 deg max) for about 2 months with no problems. Any higher it needs to be water cooled IMHO. I prefer 3DMark06 for stabilty because if your OC settings are not up to snuff it will not make it through that torture test.
First pic is to show temps under load.

This is a better link for your mobo: P5B Deluxe: BIOS screens for maximum overclocking success.

First you need to indentify the latency of your Kingston DDR2 RAM by looking at the part number and check Kingston website:

Take a note on the timings and stock voltage. Then set “Memory Voltage” in BIOS with the stock voltage per Kingston specs (keep it that way for the moment). Also set the timing (eq 5-5-5-15) in the BIOS under Advanced > Configure DRAM Timing. Also follow the xtremesystem link above to set other settings.

Basically what you want when overclocking is to get the highest FSB with the lowest voltage required. Do it slowly, in small increments. Here are some steps to overclock your Conroe system.

  1. First set the system to run at stock speeds, ie
    CPU Frequency: 266MHz, and
    CPU VCore Voltage: 1.350V
    DRAM Frequency: DDR2-800MHz
    Memory Voltage: see mfg document

  2. Download a good stress benchmark and temperature monitor and put in your desktop for easy access (see first post).

  3. Boot your PC, if it boots up then we can now start with Overclocking

  4. Raise FSB (CPU Frequency) in BIOS by small increments (10 Mhz). When you raise FSB, check DRAM Frequency not to exceed stock speed since if it gets too high your RAM may not be able to handle and your PC will not boot.
    Note: if you are using good cooling you can start from 300MHz or even 350MHz, most Conroe are known to be able to handle this frequency easily. If you are using intel stock heatsink, start with 270Mhz.

  5. Boot windows and start Orthos, run for 1-5 hours. Monitor the CPU temperature, try not to go above 60°C (personal preference).

  6. If there is no Orthos error, raise FSB by small increments (10 MHz) in BIOS. If it fails to boot or Orthos error, raise the CPU VCore voltage by 1 notch in BIOS.

  7. Repeat step 4 until you can run Orthos for hours without error. Good luck.

I’m not an OC expert so others are welcome to chip in. :wink:

nealh, I think 56°C with water cooling is too high for that speed…

Maybe personal preference but it’s also good advice.:iagree:

This is nice thread thanks zevia, it is cool for change to have different subject for discussion other than CD/DVDs. Hey, look like my son is also getting piece of action it is great. Thanks again zevia.
