My First Attempt At Overclocking.......Please Shoot Me.

[Boondawg]

I have attemped my first overclock.
Even the slightest tweak becomes unstable in 3DMark & boots me to desktop.

My System:
Asus P4PB-400
P4-2.40 Northwood
1024 333MHz DDR
Radeon 9800XT-256Mb
CPU Fan: Zalman CNPS7000B-AlCu LED
Northbridge Fan: CoolerMaster Blue Ice
GPU Fan: Zalman VF700-Cu LED
Case: Tsunami Dream
1-120mm Front Fan
1-120mm Rear Fan
1-90mm Side Fan
Ambiant Temp: 70 F
Idle Temp: 36 C/96.8 F
Load Temp: 41 C/104.0 F

I first tried a software overclock from my chip maker VIA, called Jetstream.
The stock setting was:
FSB-133.31
Vcore-1.52v
36 C/96.8 F
Worked fine in 3DMark.


I hit the "Turbo" button and got:
FSB-140.00
Vcore-1.775v
Load Temp: 41 C/104.0 F
Booted me to desktop 1 minute into 3DMark.

With the software overclock, it's stable at:
FSB-135.00
Vcore-1.500v
Idle Temp: 36 C/96.8 F
Load Temp: 41 C/104.0 F
3DMark runs fine.

So I decided to do my overclocking in the Bios.
Anything I changed in Bios, resulted in 1 0f 2 outcomes:

1. Would not boot
2. Booted me to desktop 1 minute into 3DMark.

Ofcoarse, even after reading a ton of overclocking information, thanks to you guys, I STILL don't get how to do it.
My other computer has multipliers I can adjust, but this one does not.
Here is my Bios for overclocking:

DRAM Clock:....................[166] (choices-133MHz, 166MHz, 200MHz)
DRAM Timing:...................[Manual] (choices-Manual, By SPD)
SDRAM Cas Latency:.........[2.5] (choices-2, 2.5, 3, 1.5)

DRAM BurstLen:...............[8] (choices-4, 8)
AGP Voltage:...................[1.5v] (choices-1.5v, 1.6v, 1.7v, 1.8v)
Current CPU Voltage:........[1.525] <grayed out, no choices.
CPU Vcore Select:............[Default] (choices- 1.100v thru 1.850v)
DRAM Voltage:................ [Default] (choices-2.8v, 2.7v, 2.6v)
CPU Clock:......................[133] (choices- Min.=133, Max=200, Key In A DEC Number________)

How would YOU clock this?
What's the step by step?

 

[Bleed]

raise your DRAM voltage to 2.8v or what the highest voltage your ram could take.

 

[Know Nuttin]

when you clock it to 140, can you check and see what your PCI Bus is running at? i'm not 100% sure if that chipset has AGP/PCI lock.

 

[Lt_Horn]

also increase the timings of the ram, it sounds like i was having the same problems with my oc, and when i lowerd the timeings to 3-4-4-8 i got an extra 100 mhz with my old ram.

 

[fAlCoNNiAn]

i dont think that via chipsets have pci lock, but i may be wrong.

You mean write in 140 in the highlighted red part above?
Is the PCI Bus in the bios screen shown above?

Are you talking about the timings I have highlighted in red?
If it's in the order given, I don't have a choice of 4...........

No, it is not. You may need to run software in windows to see the PCI Bus speed. Try Everest Home.

 

[Boondawg]

Try Everest Home.

Thanx!

[Shelnutt2]

Yes that is what he is talkign about.

 

[Know Nuttin]

yep, that CPU Clock is also known as your FSB. For reference in case we ask to increase the FSB.

Ah ha!
That's one of the (many) places I was getting confused! (not to hard a task)

Now I'm starting to get it.
Yea, right.
