My New Rig Is Not Oc'ing Well : (

Hi, this is my first post here so go easy on me as I am a noob when it comes to OC.

 

My new rig I just built last week

P4E 3.2 HT

Asus P4C800-E Deluxe

2x512 PC4000 Corsair XMS Speed (TwinX)

Gigabyte HSF (idle 47c, loaded 58c) a bit high eh ??

2x74GB Raptor RAID 0

1x250GB ATA133 (swap file)

eVGA 6800 (390/780)

3x Tornado (1 intake, 2 exhaust)

Stock heatsink on Nothrbridge

480W TT PSU with Active PFC

 

 

I can only OC it to 3.53 by using AI OC function but cannot get any higher without suffering some instability issues. My 3DMark03 score is only around 9000 while others with similar setup can get up to ~12000.

 

Any tips and tricks to get this thing going a bit faster that it is now. I know I might be asking for too much while being a noob but I have been doing a lot of reading online to learn about OC'ing. It's just too many schools of thoughts everywhere and I am confused most of the time.

 

Thanks in advance :D

 

ps..I am getting a Zalman 7000b tomorrow hoping to cool the CPU a bit more

A water-cooling setup as opposed to air-cooling setup would hit the spot for a good part of it.

 

When it comes to 3Dmark I would have to say maybe your video card? I dont know how well eVGA makes their boards...

 

 

also....3.5 is pretty fast man...I dont know how much more you would be able to OC it....

If I were to guess, and that's all it is I suppose... You could use more voltage on the northbridge and better cooling on the CPU.

 

You may actually need more case cooling as well.

 

3 tornadoes could work if the intake is blowing right past the CPU and is unhindered by the standard plastic/metal junk that most cases put in front of fans.

 

If it's not too late, you might consider returning that mobo and getting an IC7-MAX3. Many folks get better results with that board.

 

oh, and :withstupid: - 3.5Ghz is pretty fast. It probably won't go too much higher than that even with modifications (without water/pelt).

Thanks for the input

 

What can I do about the 3DMark score?? Seems that I am hitting a brick wall there no matter what I do. Would the low score have anything to do with DDR timings, voltage and such. If that's the case, please point me to the right direction on how to start tweaking these settings close to optimal level.

Unless you can get the temps lower, you probaly won't get the chip any higher. NW chips do not respond well to temps over 50C. Get a new cooler on the chip and try again.

 

Your 3DMark score is about right on for your system. The regular 6800 won't score in the 12K range without really high card clocks, in fact most will do around 10K. If you want your score to go up in 2003, OC your card to it's screaming limits and go for broke. CPU cards mean nothing to 2003, so get those card clocks up.

Thats a huge system, and it cant go higher than 9k?

Like I said earlier...2003 could care less about actual CPU clocks. 2001 is more system dependent, and it shows. 2003 is all video card, it shows. If you want high 2003 scores, you are gonna need a really fast video card that can OC really well.

 

The only time 2003 becomes depenedent on your system, is when your video card is bottle-necked by your CPU. These new X800 and GeForce 6 cards are severly CPU limited in most systems, so they never reach their full potential.

I got my FSB:DDR from 3:2 to 1:1 by changing the DDR frequency to 400Mhz but honestly, I do not notice any difference in performance. I might just have to get better cooling and OC the P4 more and tweak the timings a bit tighter.

 

I was able to get the timings down to 2.5-3-3-7 without suffering stability issues but again, the performance difference is not noticeable.

What would a good vcore starting point be if if want to OC the P4 a bit more, say 230-240 FSB ?? CPUZ tells me it is at 1.4v which seems a bit low to me. What do you think ??

 

Thanks again
