OCing the ECS 865PE-A

[Panda Man]

Ok, since Capper told me to make this a thread (and because he's armed...) I'll make a new thread about this.

The BIOS of my board is pretty much, locked... I can change the timings, and the frequency, and I can change whether it runs as DDR400, DDR333, or DDR266. That's it. Nothing else. IT won't let me set the dividers, changing the speed of the memory itself doesn't help, because anything past 209MHz = Disk read error (It can't detect the hdd, the optics are fine though. The HDD is SATA). Also, cpu-z still read the CAS as set to 2.5, when its set to 3 in the BIOS.

Anyways, back to my original question in the shoutbox before everything went haywire - Would you rather have the RAM set to:

200MHz@2.5-3-3-7

or

208MHz@3-4-4-8

the multiplier on the CPU is 15, so 208 x 15 = 3120MHz (CPU-z reoprts 3113.7MHz)

Hmm is the PCI bus locked?

Those are your dividers. They break down as follows:

DDR400 = 1:1
DDR333 = 5:4
DDR266 = 3:2

I own the P4P800, also on the 865PE chipset, and it sounds like the BIOS is somewhat similar. With that RAM, first thing you want to do if pushing for an overclock is drop down to a 5:4 (DDR333), which should give you more headroom. In my experience, Intel's dividers back then didn't work as well as they do for current platforms, but they do work.

So anyway, step one is to try out your newly discovered dividers and then let's see where we're at.

kinda, there is an option for autodetecting the PCI bus clock, which disabling does nothing to help anyways, I can't set it manually. And there is something for setting the AGP bus and PCI bus to a 66MHz/33MHz ratio.

Paul - Already treid that. My problem is my disk, it can't be read at anything above 208MHz

[Quakindude]

PCI-e Bus = 100Mhz

AGP Bus = 66Mhz

PCI Bus = 33Mhz.

Lock them to 66/33. That may allow you more headroom for overclocking.

[Panda Man]

They were locked by default, thanks for the suggestion though!

[Capper]

its not your HDD, and the platters don't "come loose".........

it seems your board has bad PCI locks, or that they are not configured correctly. Do you have the latest BIOS installed for your board?

[Panda Man]

yes, 2.3a. And I know the platters don't come lose capper! You know to never take me serious!

Pics of the BIOS will be up soon

FF crashed during the LAST UPLOAD!!! GRRRR.

One second.

THUMBNAILS YAY!



FAILURE!







But where is the HARD DISK!!!! OH NOES!
















Lead Head - Clock gen... I donnu the generator, can't find it listed anywhere. And then I did a bad thing, I thought I found the clock generator... I was wrong, I set the wrong one.... My motherboard didn't like that......
