E6600 woes.

[addle_brains]

It will not overclock. I am using a GIGABYTE S series, 1GB of DDR2 ram, 500w PSU. Temp monitor says CPU is never over 15 Celsius (stock cooling!) I have tried a few methods of overclocking, yet it never works and the system keeps resetting itself to 1.8Ghz (even though the E6600 is rated for 2.4.)

1: In the bios settings there is an option to OC automatically a core 2 duo using FSB1066 and 533 ram (as long as I have that, which I do.) On reboot, the POST fails and the mobo resets and goes back to 1.8 GHz

2: Manually setting OC in bios has same result.

3: Using the tool that came with my motherboard, I tried overclocking, which simply leads to the system freezing. On reboot, the mobo once again reets to the low clock speed.

firstly are you sure its a 6600? lol

second. make sure the automatic oc isnt on, set it to manual or normal settings. ..

hmm better yet.. it might be good to reset your bios(remove battery or however you wanna do it) it might be some setting you enabled without knowing or something

What software are you using to check your temps? If you're using Speedfan, it can be pretty far off. PC Wizard is typically the most accurate, besides software made specifically for the motherboard or Processor. Or...just get the readings from the bios

Update your BIOS and install your chipset drivers, the 533Mhz RAM might be the bottleneck.

Computer is only new (about 2 weeks.) The default setting for the BIOS is 1.8GHz but I am 100% certain that the CPU is an E6600. I built the computer myself from scratch. The software I am using is GIGABYTE easy-tune. Also, BIOS settings report the temp at about 20 degrees. Origonally, setting automatic overclocking would work, but now it doesn't. The motherboard is only rated for 533MHz memory so that is what I'm using. The symptom here is that no matter how I do it, the comp won't run at optimum clock speeds let alone overclocked ones.

Ah I may have found the problem:

Your CPU has a multiplier of 9, now on a 1066MHz motherboard you have 266x9 which roughly equals 2.4GHz. However your board appears to be running at a reduced FSB of 800MHz I think. This means the sum becomes 200x9 which equals about 1.86GHz. I'm thinking you have this motherboard:

No, this is a 945GZM-S2, which can support up to 1066 FSB. It may be the updated bios version which gigabyte downloaded when i installed the chipset drivers.

 

[PabloTeK]

I doubt it, you appear to be suffering the major bugbear of the 945 chipsets. It's annoying no doubt but you'll have to overclock to get up to stock speeds.

This is the problem. I cannot overclock! If i overclock in BIOS, during POST I can briefly see it display the new clock speed I set and then it gets halfway through the POST and the system resets. I've looked at all the setting and I can't find anything.

Jack up themultiplier? then overclock . ARe you making a HUGE jump? like 100MHZ?

 

[PabloTeK]

The multiplier is maxed at 9 already, you're probably best asking Rambo about overclocking seeing as he's good at it.

Lets ask the almighty Rambo who knows all

 

[PabloTeK]

Well he seems to be able to overclock well with his Gigabyte. Incedentally [-0MEGA-] what temps do you get?

 

[bluedishwasher]

try increasing the voltage to the CPU? that mgiht be a problem

 

[xxxalpinexxx80]

call gigabyte they should tell u exactly whats wrong and what to try

 

[INTELCRAZY]

It has to be that 945 chipset, it sounds right.

 

[Geoff]

Well he seems to be able to overclock well with his Gigabyte. Incedentally [-0MEGA-] what temps do you get?

I get around 35-45C idle, and around 60-68C load.

 

[PabloTeK]

Is that with the stock or aftermarket cooling?

 

[Geoff]

It's with an aftermarket cooler.

As long as it doesnt hit above 70-72C under full load, then it's fine.
