Overclocking problem

post #1 of 13
Thread Starter 
Alright my setup is in my sig, just built it yesterday It was fine stock at 2.4, 266 FSB with X9 multiplier, everything ran fine, temps were 36c at idle, and around 41 at load. Today i booted the system up, its set to 1700mhz with a X6 multiplier? So i go into bios and use 400FSB with the X6 to make it back 2.4 and it will not boot, i have to reload stock bios settings. Im new to overclocking so go easy on me and if theres a thread that clearly explains what im doing wrong, then please point me in that direction


Thanks alot guys

hello and welcome

wit your processor, you only want to use the stock x9 or a x8 multi. don't go lower than that. you won't be able to get 400x9 on air. if you want a 1:1 ratio with your memory, you can easily do 400x8 for 3200 MHz with your equipment.

The CPU is at the X6 multi because you have speedstep enabled. It might also be called EIST in your Bios. It should be under your CPU settings. Just go in and disable it. Anyway, it works by throttleing back the CPU when you are not utiulizing its full power. Its the same tech they use in Laptops.
With your current settings, you should set your FSB to 400 x8 and make sure your vcore is at 1.3v. If that doesnt work for you, leave it at the default X9 multi, and run the FSB at 360. That will give you 3.24GHz, and that should run at stock. Mine runs at 360 with 1.21V vcore!

Yes but i have no access in my bios to my Multiplier, i have looked through every portion, i just go to jumperfree settings, and change to manual and change the FSB, i do not see anything to do with the multiplier that is why i am asking, why did the frequency and multiplier go below the stock settings? and How do i change the multiplier if its not in bios, and set 1:1 ram ratio?

lowering your CPU multi raises the system bus on your motherboard. that is probably why your OC was unstable. lowering your multi by 1 isn't a problem though. to access your CPU multi:

Advanced / Advanced CPU Settings / Modify Ratio Support - Enable

that will allow you to change your multi. if you want a nice starting point, try this.

Advanced / Jumper Free Configuration
AI Tuning - Manual
CPU Frequency - 360
DRAM Frequency - DDR2 800
PCI-Express - 100
PCI - 33.33
Spread Spectrum - Disabled

Advanced / Advanced CPU Settings
Modify Ratio Support - Disabled
C1E Support - Disabled
Max CPU ID - Disabled
Vanderpool Technology - Disabled
CPU TM - Disabled
Execute Disable Bit - Enabled
PECI - Disabled

you should be able to do the above OC with stock volts. i recommend setting those voltages manually though. also, make sure you set your memory timings manually - that is in Advanced / Chipset / Northbridge.

EDIT: C1E is what is lowering your multi, btw. make sure you have that disabled.

It wouldnt boot at 400 FSB because the actuall multi is 9. The OS drops it to x6 according to the Speedstep being enabled. So your actual multi during boot (post) is 400x9=3.6GHZ. With my water cooling kit, I can boot at that, but I have to up my vcore to 1.4v. The intel specs are between 1.18v and 1.35v. You should be able to set the CPU manually at x8 with 400 FSB = 3.2GHz, but I have to up mp vcore from 1.21v (3.24GHZ w/ 360FSB x 9) to 1.325v to get 400 x8 = 3.2GHz. Supposedly, the higher FSB yields better performance.

I strongly recommend that you take the time to read through Pauldovi's Intel Overclocking Guide before you carry on trying to overclock. It's got pretty much everything you'll need to know with regards to overclocking Core 2 CPU's. Be sure to give Pauldovi a Rep if you find his guide useful.

The guide will also enlighten you as to why your multiplier is being lowered to x6. EIST will need to be disabled from within your motherboard's BIOS along with C1E aswell.

Let's go for something more simple and easy to follow, shall we?:

_________


1st pic:
With BIOS 1004, I'm able to do a 350fsb easy and also locking the PCIs to 103 and 33.33mhz respectively in order to not have SATA corruption. And everything else set to AUTO.

2nd pic:
Everything set to the default BIOS settings, nothing changed. Leaving all power saving features which will allow the CPU to run with a x6 multi in order to save energy and not wasting CPU cycles.

3rd pic:
The most important part because it's here where not everyone have the same modules, some can do it some won't.
Basically, if these settings cause the system to hang? It's best to use 4-4-4-10 or 4-4-4-12 with up to 2.20v but 2.10v should be tried first.

The final result is a CPU clock at 3.15ghz with EIST & C1E enabled, it runs at 2.10ghz when idle and 3.15ghz when it needs it.

I could try higher but then some settings will have to be changed but this is the sweet spot for me. So, this is where it's at!
