[CPU] E6750 Overclocking need help please!

[pbear]

Hi everyone, this is my first post..!

Alright, so with my fresh addition to my setup (OCZ Platinum XTC PC2-6400 4GB 2X2GB DDR2-800 CL5-4-4-15 DDR2 240PIN Dual Channel Memory Kit) and Vista installed, I wanted to test my overclocking capacity.

However, after a quick peak in the BIOS, I was surprised to see that all my efforts would give nothing. Sometimes I get "Overclocking failed", or the other time I just can't boot because it seems like my SATA drives won't get detected.

My FSB was set to 400 and my CMOS to 8 (wanted to reach 3.2ghz). CE1 and Speedstep disabled, along with the normal options also disabled.

Am I doing anything wrong, am I missing something?

Here is my config :

-OCZ Platinum XTC PC2-6400 4GB 2X2GB DDR2-800 CL5-4-4-15 DDR2 240PIN Dual Channel Memory Kit
-Intel Core 2 Duo E6750 Dual Core Processor LGA775 Conroe 2.66GHZ 1333FSB 4MB Retail
-Nine Hundred Antec Case
-4 Normal Fans
-1 120mm Fan
-OCZ GameXStream OCZ600GXSSLI 600W ATX12V SLI Certified CrossFire Ready Active PFC Power Supply
-Asustek P5KC Motherboard

Thanks alot in advance!

My 6750 on a ga-p35-ds3l board runs overclocked to 3Ghz FSB 375 mult 8
rock solid.This is with cpu NO VOLTAGE increase. Will your setup do this?It should. Over 3Ghz you will probably need to up your voltages.

What else have you changed except your multiplier and your FSB ?

Could you list me the exact changes you've made in your bios please?

Thanks alot!

I run this CPU at 3.2ghz. on a Gigabyte board that supports 1600 FSB.
My settings: FSB 400, CPU voltage 1.31v, DDR2-800 Ram 1:1

Your MB acording to Asus supports max of 1333 FSB. 4x400=1600

Try a lower setting untill you find one that is stable. Work up from 333 not down to.

Here is some info that might help you:

Are you sure that your Memory is in the right slots? Orange is for DDR3

Alright thanks, I'll check that out..

In the meantime, what do I really need to change in the memory settings?

 

[pbear]

Alright, I'm ready to overclock but not too sure about what to change in the memory options. I won't touch the voltage settings but I'm not too sure what must be changed in the bios to make the RAM follow the o/c. This is the pattern I'm following but my RAM isn't the same one that they tested.

I run my setting with this OCZ Platinum XTC PC2-6400 4GB 2X2GB DDR2-800 CL5-4-4-15 DDR2 240PIN Dual Channel Memory Kit.

CPU Frequency 3.00 GHz (+12.8%)
FSB 375 MHz (1500 QDR)
Core Voltage Default
Memory Multiplier 2.40x
Memory Frequency DDR2-900 (450 MHz)
Memory Latency CL 4.0-4-4-12

 

[iluvgillgill]

lower the memory multiplier to 1:1 and put 2.1V on your memory.raise FSB to 400 and with 8x multilpier.up your Vcore to about 1.4v.

 

[pbear]

I think my mobo won't go as high as 400 FSB with this multiplier is it possible?

 

[iluvgillgill]

if the mobo can do 400FSB then yes.you will need to list all the option in the "Cell Menu" from BIOS otherwise i cant help you!

 

[pbear]

Cell menu? The one with the RAM and CPU settings?

 

[iluvgillgill]

=.= of course!the place where you do the actual overclocking!><

 

[pbear]

This is an answer for iluvgillgill and also a bump if anyone has a clue on this setup.

Here is what I see in the BIOS :

AI Overclocking
CPU Ratio Control
FSB Frequency
PCIE Freq.
DRAM Freq. (It's on auto right now, can chose from DDR2-667 to DDR2-1333mhz)
DRAM Timing Control : 5-4-4-15 is on

TWR
TRFC
TWTR
TRRD
TRTP

DRAM Static Read Control
DRAM Dynamic Write Control

Transaction Booster
Clock over charging mode

CPU Spread Spectrum
PCIE Spread Spectrum

CPU Voltage
CPU Voltage Reference
CPU Voltage Damper

Then, I have a list of voltage options, including :

CPU PLL, DRAM, FSB termination, NBridge, all voltage controls.

Thanks
