I think your CPU has hit the wall already. Anyway, for Intel, there's negligible differences of 200MHz. So, why not just permanently drop the frequency to 3.74ghz to run FEAR without problems.

Anyway, what heatsink fan do you use? Perhaps turning to something in the likes of Thermalright XP-90c might help you better in your endeavor. The cooler the CPU, the less likelihood it will crash.

NF4 C19 Chipset issue i believe..i did 3.975mhz using NF4 SLI Intel edition too..up abit fsb..wont boot.. my proc running at 1.475volts...everything runs ok..
im still tweaking tho..I want my 4Ghz!!

try lower down ur ram fsb..up ur pci-e voltage one notch..LDT 3.5
hope it helps.

^ ztlee: are you running on stock or performance cooling?

i am running it this speed at china brand water cooling

I am currently on Stock heat sink, with serious watercooling coming soon . But why does Fear crash out to windows. Tried upping chipset voltages, still the same. (Note: computer/windows does not crash, only Fear exits to windows)

Anyway, my goal is to reach 4.5Ghz on the 630 intel chip. This 4.5Ghz oc was easily done using the 630 chip on an Asus P5WD2 mobo I think. Do a google and u'll find it. So I do not think I have hit a wall on the processor.

Who is the manufacturer of your mobo anyway?

I have not heard any issues with the NF4 chipset hitting upwards of 4.0ghz. Will google this abit and see what is up with the NF4 chipset issue. If this turns out to be true, I may have to kiss my 4.5Ghz ego trip goodbye. (Better still, this maybe my a reason to get a new mobo) The fact that the 4.5Ghz oc was done on another mobo does lend some credibility to your claims that there may be some issues with the NF4 chipset.

Could be a bios problem, read that there was plenty of problems with the bios on the premium version of my mobo.

I have tried all that you have suggested and the results were the same. Ram at stock (667Mhz) and at oc (800Mhz) is the same. Chipset voltages have not impact to the stability of FEAR or the ability to break 3.975Ghz barrier.

im using gigabyte GA-8N-SLI mobo.
ive always tot my proc was the problem...but during tweaking my mobo..i found out my 630 can actually run at 3.9ghz at default voltage (fully benchable ..3dmark, superpi, prime95, games....all this while was upping voltage to get it stable.

to get 4.5ghz..as far as i know..only two mobo can do 300fsb n above..Asus P5WD2/E & Abit AA8XE..

here's a link to Nf4 Intel Sli overclocking results.
most crap out ard 260+fsb...

Guess its time we change mobo huh..

Thanks for the links. It is indeed a sad day for NF4 intel edition. But change mobo to what to keep the SLI capability.... can the NF4x16 mobos do better?

Else may have to consider the intel 955 based mobos..... IF we intend to stay with intel.... could always jump onto the 'other' bandwagon.

By the way still kennot find the solution to my FEAR instability.

I have a Pentium 4 Prescott (P4E) 2.8Ghz. I tried using the Clockgen software to overclock but failed even by a little bit. How do i unlock my processor anyway?

Using stock HSF with Intel D865PERL mainboard. 800mhz FSB 4x256mb Kingston Rams.

Mainboard = motherboard rite? not so sure abt that.

Im newbie in this kind of stuff. I've oc my cpu to 2.9. Issit posible to increase more? Im using a stock cooler for and the temp now is arround 47c. I saw some ppl post that the votage or anything else need to be adjust too. So, can any of u guys here help me out with this. btw, im using an p4p800se asus mobo

Here's the summary of it:

any soft modd to overclock my machine, try to search for it.. didnt found it

Product: ThinkCentre A51 8123-KAB [change]


Operating system: All [change]

Original description: Based on 8123-32A: Intel® Pentium® 4 Processor 515, 256MB, 80GB 7200RPM S-ATA HDD, PCI Desktop (3x4), Intel Graphics Media Accelerator 900, 48x CD-ROM, 10/100 Ethernet, Windows XP Professional


thanks guys

Intel locked their mobo in term of overclocking.. Luckily sometimes it is possible to use software to do the job, but i can confirm u'll not get a good result..

u satisfied with the result already?..

IBM izzit?.. the mobo being use is Intel?..

Intel D865PERL? with this board or any Intel board in particular, obviously you will have no chance whatsoever to have fun with overclocking. This is why I never recommend Intel to the enthusiast.

Well the com was bought like wat, 2 years ago. Didnt have knowledge on these things back then.

not really satisfied. but if it goes more than 55c will my processor fried or mayb damage? :confused;

increase ur fsb more.. keep the current voltage.. and see how the result.. that is normal temp for presscott.. u need to be prepared for a better cooling solution for sure if u want to go furthermore..

as long as throtling does not happen...you are find. when throtling do happen, its the sign of overheated cpu. but lower temp is always better.

Hi i'm noob in OC. Is my processor and motherboard suitable for overclocking?

Below is my system spec:
CPU : Intel Pentium 4, 2800 MHz (14 x 200) 800FSB L2:1024KB on Cooler Master Jet 4
MOBO : Gigabyte GA-8IPE1000-G
RAM : 1.5GB Kingston Value Ram DDR 400
PSU : Enermax EG465P-VE (460W)
DC : Grandmars Redeon 9550 Infinite (Core:400 / Memory:700)

[attachmentid=87584]

[attachmentid=87585]

Can anyone guide me for Overclocking my system?

Thank a lot.........

yes..can overclock..i865pe ? overclock with two pieces ram..three pieces no good...up fsb at 5mhz ..test stability..run prime95 for one hour..if no error...up 5mhz again..test again..keep going until proc hang or reboot..up voltage one notch..go again..max temp for p4 ard 60-65'c..wats ur proc default voltage?
overclock ur system with chassis panel open..better air flow..

yeah that is one of the best board around for P4 s478 i think..
u will find a lot of useful article frm here as the guidance.. trust them..
