need help with overclocking 2.4ghz northwood

post #1 of 9
Thread Starter 
I have the specified cpu running on GA-8Ipe1000 Pro and sucessfully overclocked it to 2.88ghz, but I failed to go any further, as my system would freeze up when windows is being loaded. I have tried to increase the cpu voltage a couple of times, but the system still freezed. It appears that the bios doesn't provide me the option to change the RAM timing. Here is the list of the Frequency/Voltage Control Menu:

CPU Clock Ratio (not shown since my cpu has a locked ratio)
cpu host clock control enabled
cpu host frequency 160
AGP/PCI/SRC Fixed 66/33/100
Memory Frequency For [Auto]
Memory Frequency (Mhz)
AGP/PCI/SRC Frequency (Mhz) 66/33/100
DIMM OverVoltage Control [Normal]
AGP OverVoltage Control [Normal]
CPU Voltage Control [1.550V]
Normal CPU Vcore 1.525V

Now how do I have my cpu go further? The temperature is still low(about 34 degree celcius) and I am able to increase the cpu vcore.

Here is what my system looks like:

System Specs
CPU: Intel Northwood 2.4 Ghz
Motherboard: Ga-8IPE 1000 Pro
Memory: Kingston PC2100 256MB * 2, Kingston PC2700 512MB * 1

Welcome to Overclock.net
if you go to user CP > edit system specs, you can fill in your specs and they'll show in your signature so everyone can see them.

I think your RAM is holding you back from ocing any further.
Can you tell me which speed it's rated to run for?

Anyways It's on a 4:5 divider, so you can put it in 1:1 ratio to start with, then try again on upping FSB.

Edited: had missed the last pic

By the way, how do I change the 4:5 ratio back to 1:1?

As I thougt.
You have 2 chips rated to run at 166Mhz and 1 chip rated to run at 200Mhz.
(We're being held back by the slowest chips)

Now with your divider (FSB:RAM) being 4:5, your RAM is running faster then your FSB (your FSB is at 160 whilst your RAM is 200)
That means your RAM has been overclocked from 166 to 200 and at that point it craps out on you.

What you need to do is go into your BIOS and search for either a FSB:RAM frequency and change that to 1:1 or search for your RAM frequency and change that from Auto to 166 (may differ - choose the option that's equal to your FSB, or the double of it since it's DDR).
Then open CPUZ and check in the memory tab to make sure it's in 1:1 ratio.

[If you're unsure, just look at what options you have available and post them back here.]

Then you can continue raising the FSB.

And keep your Max temps under 55° @ load for a Northwood and about 1.7 max Vcore.

No... you have 2 RAM modules that are rated to run at 133Mhz and 1 rated at 166Mhz.

I'd recommend getting some PC3200 (200Mhz) RAM just to give you a bit of headroom, this would also allow you to run your RAM at 1:1 and give you a larger bandwidth which will increase performance.

What's in his sig isn't the same as what's in his post from PC Wizard 06..
It states PC 3200 (200 Mhz) DDR-400

Either way, setting the 1:1 divider would still help (even if it won't get too far either)

Thanks for the advices

I have set the memory frequency to 2.0, so that the fsb:Ram ration is 1:1, and I raise vcore to 1.68 with fsb raised another 5. CPU temp gets to 45 degree and windows runs as usual, but it fails to do further operations like running cpu mark and restart automatically.

By the way, what is the good memory for oc?

Hi, im in the same position lol. I have the same 2.4 NORTHWOOD 533fsb proccesor but my board only supports 3Ghz. I recently bought 2 GB sticks of cheapo ram and it states it can run at DDR333 (pc2700) but i have instability and decided to set it at DDR 200 (pc 2100). I have a sis 648 chipset and have a north and south bridge.

IMPORTANT: Something is strange my board and cpu supports 533 fsb so y under cpuZ it says fsb is 133!!! God id feel damn stupid for letting it under perform for almost 3 years now... So look at the pic and see is it alright, is my bus the 533 thing or is it what i believe, under performance


In bios my ram or whatever divider is 4:3 and my something clock (Called SW clock in mine) is 133 when i looked. My bios is phoenix and the date of it really really old (02), just didnt get around to flashing it cause of doubt and fear. Some help please id tottaly like to overclock

no, your fsb is running at 534 in that picture... look at the BUS speed under the fsb speed. thats your processor 'fsb rated' speed. the 133.6 speed is multiplied by the multiplier(18) to give you the clock speed of 2.4ghz. your computer is fine.

you really need to upgrade your ram before oc'ing much more. and make sure you get all the same speeds. ie, i just ordered 4 256 sticks at ddr500(pc400) so i have lots of room to grow.
