Hey all,
I'm having trouble overclocking my CPU.
Here are my specs:
  • Gigabyte GA-P35C-DS3R (F10, Rev 2.1)
  • Corsair 620W PSU
  • Q6600 G0 stepping (with Noctua U12-F, via Artic Silver)
  • 8800GTX
  • GeIL (4x1GB) PC2-6400C4 800MHz Ultra Low Latency DDR2
I was able to overclock my last system (AMDX2) just fine, but whenever I follow instructions from this forum to overclock this new system, it just keeps restarting after POST until I clear CMOS.

I know this is an odd request, but could someone give me specific instructions on what settings to change in the BIOS? For a decent OC of 3Ghz.
Here are photos of the different menus:

Advanced Bios Features | Power Management Setup | PC Health Status


MB Intelligent Tweaker (MIB) page 1 | MB Intelligent Tweaker (MIB) page 2
 
There's a good Gigabyte guide at the top of the Motherboard forum. It's based on the P965 boards, but the P35's use the same settings.


The most important thing is to set the System Memory Multiplier to x2.0. That takes the memory out of the equation.
 
Odd. There should be x2.0 and x2.4 options. Are you sure you went down to the very bottom of the menu (it starts in the middle of the menu, so there's options above and below the Auto setting).

If so, then it's currently set to x3.0 via the Auto option, so set it to x2.5. That'll drop the memory to 667mhz.

Also set the Performance Enhance Option to Standard.
 
Got one of those bad boys myself - they are a bit funny. Just set the memory on the lowest divider and go from there. Put the volts up a bit as well. On my e2180 @ 3GHz, I've got 1.45V through the CPU and +0.2V on all the other voltages.

Ok so I followed the instructions from here:
http://forums.overclockers.co.uk/showthread.php?t=17610180
Including manual RAM timings, +0.1v to GMCH and FSB, and +0.3v for DRAM. FSB to 311 for 2.8Ghz clock.
Guess what? The system again reset just after POST, and all the changes I made were reverted. So no overclock :mad:

I have the same problem with my GB MB, I just cant get it to OC !!!

Everytime I try to OC the system locks up !!! Perhaps GB have had a bad batch.:eek:
 
I have a strange problem. I've managed to overclock the CPU finally, but for some reason the Vcore goes from 1.39 at idle to 1.33 when running Prime. Yet in the BIOS I have set it to 1.45. :confused:

Edit:
Alright I've brung the system up to 3Ghz stable on 1.4v. Temps start reaching 70C if I turn the volts up much more.
I have a problem though - Since the board only has a memory divider of 2.5 (rather than 2.0), if I turn the clock up to 3.2 (355x9) then the RAM goes to 890Mhz, which causes me to be unable to boot into Windows. Any solutions?

Hmm bunch of questions.... some answers...

What's your cooling? If you're hitting 70C and you are stillon stock - time to invest in a decent after market one.

Listen mate - there is no way Gigabyte are going to provide a BIOS without a 1:1 divider. That 2x multiplier is there somewhere ;)

What's wrong with Coretemp? Have you tried TAT? Speedfan under reads by a good 10C - so be careful.

Regarding your BIOS screens, suggest:

PCI Express to 100 not auto
performance enhance to normal
disable CPU EIST function until you're done overclocking - that's speedstep.
 
Hey,
I have a Noctua heatsink with a Sharkoon 1000.
Even after disabling driver signing, CoreTemp doesn't load - Saying "The Driver has failed to load! Some information will not be available."
What is TAT?

Edit: Sorry guys - I've found the x2.0 multiplier :p You can all officially call me a noob now.

Btw, is it always best to keep the Memory Frequency as close to stock as possible? (800Mhz)

Weird... TAT's window pops up for a split second and then dissapears. So I can't use that either. Oh well; Everest suffices I think - although it shows temps 20C higher than Speedfan's...

I am running Vista 64 btw.

Edit: Managed to get CoreTemp working again after downloading a fresh copy and following instructions from here.
Temps are the same as reported in Everest afterall: around 50C idle; nearly 70C full load (this isn't normal right?).
My VID is 1.2625v and Tjunction 100C. Are these normal?
Btw, clocked at 3.2Ghz now on 1.425 vcore :cool: Think I'll leave it there so my system remains stable for 2 years.
