Calling all l33t OCers!

I'm in a major bind. Before I tried OCing my pentium 4 630 and could only get to 3.27 ghz before the system wouldnt activate the monitor. The people here suggested I buy a new cooler so I got a big typhoon. Problem solved? Unfortunately not. Besides my computer being much quieter I can't OC it over 875 bus speed. So please, pro OCers help me out this is killing the child in me :[!

My setup:

Aspire X Cruiser

7600 GT xXx edition with NV silencer 6

Thermaltake big typhoon

Pentium 4 630

ECS C19 A-SLI Motherboard

Pqi Turbo 1 gb (2 x 512mb) stock at 667 mhz ddr2 with heatspreaders

And I think that's about it...

I've read people have actually gotten atleast a 250 mhz fsb speed on this mobo.

Thanks!
 
Hello, spiritd. First off, nice CPU heatsink purcahse :). How are your temps after installing it? The first thing I notice when looking at your setup is the ECS C19 A-SLi motherboard. It's an ECS, generally not for OC'ing, AND it has the nVidia SLi chipset for Intel, not good for OC'ing either. I'm sorry man but in my opinion it might be your motherboard holding you back. Have you tried changing the memory divider so its underclocked, ruling that out? What PSU are you using too, I hope it's not the one that came with the case...

What kind of voltage are you running through the processor? If you're only running stock voltage then you can safely bump that up a litte bit with the purchase of your nice new heatsink. That alone may hold you back, but you didnt mention anything about the voltage that you're running through the chip.

Does your BIOS give you voltage adjustment options? I know that some of the lower end mobo's won't let you change the voltage. Even though ECS isn't a "preferred" oc'ing board I would imagine it still has voltage controls.

On the lines of what Nick said, I reallllllly hope you're not using the PSU that came with that case. If so, shut down your computer right now, go out and buy a new psu because you're in danger of frying every component in your computer at random split second when the psu decides to blow.

Hope we can get this sorted for ya and get ya running @ some insane clock speeds. Keep us posted with updates as to how you're getting along.
 
Thanks, and no. I'm not suicidal O_o! I have a 585 watt psu from HEC (used to amke Antecs) it has like 38 amps on the dual 12Vs and my volatage is set on auto atm. Also, after isntalling the BT my idle temp for my processor is around 35-38 Celcius. And in the reviews I read people ahve actually gotten pretty nice OCs on this mobo, and I have no clue at all about memory timings...*nubzOrz* thanks guy!
 
Your processor has a variable vCore due to Speedstep technology.

Here is the information about your processor: http://processorfinder.intel.com/scripts/details.asp?sSpec=SL7Z9

With SpeedStep disabled, your vCore should be 1.388V... so try 1.400v or around that.

EIST and C1E Halt State - EIST - or Enhanced Intel SpeedStep - in combination with C1E Halt State is a godsend to frustrated Pentium 4 users who found the heat generated by the Prescott gave them issues (usually related to other parts overheating, as the P4 can stand quite high heat levels before having to be throttled down). EIST works a lot like it does on the Centrino platform - the multiplier is set to a low level when CPU usage is not very high. For instance, while browsing web pages or writing emails. When the CPU has to kick in, to play games or processing images, etc, the multiplier is raised, and the CPU runs at full speed. This is all transparent to the user, and works flawlessly in my experience.

I know there are better boards out their but see the problem is I cant afford them =\ I wish I could. But I think we are all agreed that my FSB can be raised higher so I need to isolate the rpoblem and since all the reviews I've tead have gotten 250 fsb I think I need to isolate the problem. Any srategies to do that?

system wouldnt activate monitor? hmmm agp or pcie? and have you locked the agp/pci bus

I'm guessing he meant it didn't post.. ;)

You're loosing your touch Davos, wake up.! :whack:

That's not always the case. I've tried 2.8GHz on my CPU and it didn't post... but then again all I had to do was press the reset button and hold Insert to get it to post. (Little trick with certain mobo's.)

Nick
 
When I bump the Bus speed to over 876 mhz the computer doesn't post and the lights keep going in a reboot loop after every 10 seconds (the lights go on 10 seconds later they flash and it keeps going in a loop)
 
yea thats normal for settings that just wont work. alot of recent bios' have a feature where the bios resets to default when the loop goes round a cirtain number of times
 
Right, i no **** all about intels and they're fangled DDR2. But just throwing the idea out there. Could it be the memory?

On the 1st page of this article:

http://www.overclockercafe.com/Articles/DDR_vs_DDR2/index.htm

It shows a table. I notice the Dram frequency only goes up too 166, whereas the bus speed is twice that. Could this have any implications? Or is it a stupid idea and ill be quiert and go back too my AMD shack...
 
That's not true. The article must be wrong or highly dated. The highest JEDEC rating is 333.5MHz RAM freqency, or DDR2-667 (PC5300 iirc).

You can purchase memory that runs at 400MHz, AKA DDR2-800, or even 500MHz, aka DDR2-1000..
