New to P4 overclocking, need help

Recommended Posts

Trust me 875pro loves tccd, i mean loves it :)

I would really be suprissed if it was your ram...

Jack the ram volts to 1.8... AGP to 1.7

loosen up your timings if you dont use a divider.

I run 1.58 cpu volts with air....

 

I have a revA board, so those vdimm and vagp settings are unavailable to me.

I think you might be in for a good flashing to the 04/09/2004 Phoenix bios...

I was under the impression that all 875pro boards had the agp,vdimm,cpu overvolting options, guess i was wrong... Any how the only diffrents in the a rev. and b is that the Rev B is prescott ready....

Maybe Ace can help you out a little more on bios, but you should be able to overvolt those settings...

In the manuel at the DFI web site it cleary stats that you should have overvolting options.......

 

BIOS

 

 

# Award BIOS, Windows® 98SE/2000/ME/XP Plug and Play compatible

# Genie BIOS provides:

- CPU/DRAM overclocking in 1MHz stepping

- AGP/PCI/SATA overclocking

- CPU/DIMM/AGP overvoltage

# Flash EPROM for easy BIOS upgrades

# 4Mbit flash memory

Ok quick review of your situation....

You have a P4 northwood 2.4 @ 200x12

you have 2x512 tccd 3200 @ 2-2-2-6

OCZ powerstream 420w

And your bios will only allow 2.7vdimm, 1.6 AGP

 

My question is first off what kind of overclock are you looking for?

Second whats the highest vcore setting that you have?

Also i noticed that you have a stock cooler?

 

Also have you tried a divider to see exactly what your core can do?

 

In your bios do you have the following DISABLED?

 

System Bandwidth..

Auto Detect pci clock..

Spread spectrum..

I was hoping I could do 270+ 1:1.

 

Max vcore is +350 mV or 1.85.

 

Yes I am using the stock Northwood cooler.

 

I didn't go very far or test very extensively, but I did 250 fsb with no vcore increase, max vagp, and the RAM set to 3:2 2-2-2-6. I messed around with 266 fsb 3:2 with a .1 bump in the vcore, but I didn't run any stress testing programs for very long.

 

System bandwidth is set to HPS3 when at stock and various LPS settings while I try to overclock.

 

Auto Decect PCI clock enabled.

 

Spread Sprectrum disabled.

Now where getting some where hehe..

Disable System Bandwidth..

Disable auto detect pci clock..

Now go ahead and put some volts in that cpu, no worries just watch your temps...

With out uping the volts on your cpu it is highly unlikely to get things stable..

2.4 northwoods are some of the best overclockers and love to get a little more juice in them, i crank mine up to about 1.56 in the winter, summer time i drop it down alot considering im in Denver and its been like 107 everyday..

You should really get your self a new cooling solution.. I got the Zalhman 7000 and it rocks, 800mhz overclock with 52-54c full load...

But you have one of the greatest Intel overclockers with that 2.4 so get your self something nice to put on it to keep it cool...

Try 2.7 vdimm, 1.6 AGP, 1.56 vcore, 12x250fsb and a 5:4 divider with tight timings 2-2-2-5 and see what happens :nod:

 

Honestly with out better cooling you will not see 270fsb..

I tried what you said except for the 1.55 vcore, and man does the vcore droop. I tried running a SmallFFT and modified Blend at the same time, and the Blend crashed after 3 minutes. I also saw the vcore drop to 1.42 according to CPUz:eek: Do you know of a vdroop mod or something else I can do to alievate this?

 

If I do go for a new cooler, I'm thinking a Prescott cooler or this.

I think I fried the board. I moved my 250GB hard drive onto the IDE RAID port to move and backup some data, and when I powered on again I smelled something burning. Now it won't give me any video, and hangs on the 4th LED or "Early Program Chipset Register before POST". I checked the board up close but I didn't see anything looking roasted.:(

It's dead:sad:

 

My new question now is do I find a new s478 board to put my 2.4C in and buy a better CPU cooler, or take advantage of a sweet price on a 875p-T and 2.8 Prescott and buy a better CPU cooler?

 

I'm thinking of using the Thermalright XP-90 in either case. As for the fan, do the beast 92 fans (ie Tornado, Panflo, etc) come with a temp sensor like the TT SmartFan 2?

What happened to the PR0875b? Sorry to hear its fried...

Good time to upgrade... Depending on what you can spend..
