Help OCing Intel Prescott 3Ghz

post #1 of 14
Thread Starter 
Hello all, this is my first post... so hi!

Anyway, I just started OCing and managed to get my processor up to 3.6
http://valid.x86-secret.com/show_oc?id=70825

I'm just wondering how far I can push this thing (And how, exactly to do it!) I didn't use the stock CPU fan or thermal paste. Got some AS5 and the freezer pro cpu fan, so the computer is running at 23c idle with the fan on its low setting and does not go above 40c when under a full load.

All I have done so far is increased the FSB values to 1050 and it worked. Prime95 ran clean all night.. so time to push this baby further. My specs are below, and thank you in advance for the help!

My new computer consists of:
MB BIOSTAR TForce4U-775 NF4U 775 (Motherboard)
CPU INTEL|P4 630 800M LGA775 2M R (CPU)
MEM 1G|PQI DII667 PQI25400-1GSB R (RAM)
VGA SPHRE A X1600PRO 512M 100145L R (x1600 ATI card)
CPUCOOLER|ARCTIC P4|ACFZ7-PRO R (CPU fan)

all i would say is if ur cpu temp, mobo and ram does not limit u, u can easily do 3.9 or even 4.0GHz....but take extreme good care of the temps....

we have similar cpus so thats why i am so confident....u can do easily in that range...


i would actually suggest u play with the ram timing and then slowly increase the fsb, i just increased ever so slightly the volts for my ram to make them stable....

as for the cpu i will give u a hint...u dont even need to increase the volt..in fact u probably would just need to maintain it exactly where it is....
good luck mate....

Your multi is at 14. You have speedstep enabled. If you disable speedstep you will get back to the 15 multi of that 630. With the Multi at 15, the fsb at 266 you will have the 1066 bus and a 4GHz overclock. I believe your board boasts the 1066fsb.

I have done this with an P5AD2-E Premium and i630. Made the 1066 fsb easy to a 4GHz overclock.

This is the only board I can find of Biostar with Nforce SLi:

Is this the board? If not, please give the url to the board.

Gah! I'm sorry. If you copy/paste what I put (i.e. MB BIOSTAR TForce4U-775 NF4U 775) into the newegg.com search it'll come up.

The MB i'm using is http://www.newegg.com/Product/Produc...82E16813138276

As for RAM timings - I just see four numbers. No idea at -all- what to do with them. I'm guessing increase them (duh!) but how much at a time? Are there any I should not touch?

Also - What is speedstep, and how can I disable it? I don't think I saw an option for it in the bios.

Thanks again

speedstep is sometimes displayed under Intel Speedstep Technology..
look there...
btw u should slowly and one at a time REDUCE not increase the numbers...increasing means worse performance

reduction means better performance...and those are ur ram timings; cas, ras, trd trdc if i remember well....

but u can find out better under the ram timing FAQ

i'll get u the link

have you locked your PCI/PCI-E ?

as for RAM timings, I'd suggest you first try to reach your highest stable overclock before you start tightening your RAM timings, 'cause if you tighten them now you'll just have to loosen them again when you continue to oc higher.

One of the reasons for researching a motherboard and purchasing one that is from a quality manufacturer is for the support that quality should bring.

Here is the link to your motherboard on the Biostar website. Follow to find the manual. You will notice there is no manual download.

http://www.biostar-usa.com/mbdownloa...el=TFORCE4%20U

It will be very hard to help you without the manual. In the future it would be a good idea to research before you purchase motherboards and choose from more reputable companies if you wish to overclock.

Do you have a CD with the manual? If so, please send it (and this url) to:

ropey@spymac.com

You can push it farther, I have P4 3.0ghz Prescott and I have mine running at 3.98ghz. To get it to be stable at this though I had to increase the ram voltage 1.9 volts and bring the vcore up slightly. Cooling can be an issue but it sounds like you have that covered already. I have the artic cooler freezer as well as I'm at 33C at idle, 44C under load.
