P4C800ED - After move to SATA connectors, cannot overclock like before

Hi, I have the ASUS P4C800ed with a P4 2.4c CPU and 4x256 of cheap Elexir
DDR-400 3200 RAM.

When I first installed the memory, my hard disks were connected to the IDE
connectors on the motherboard, and I had 3 optical drives installed (DVD
writer, CD-RW and DVD reader).

I then set the BIOS to 30% overclock and had no problem running at 3.12Ghz
at a CPU temp of about 44 degrees celcius (according to Motherboard
Monitor).

Now today I made some changes to the machine:

- removed CD-RW and DVD reader and replaced with combo CD-RW/DVD drive
(Samsung)
- installed an PATA to SATA dongle to each of my hard drives to be able to
connect them to the SATA connectors on the P4C

I now find that I can no longer overclock my machine. At 30% or 20% it
won't boot at all (monitor is blank and HD light stays solid) and at 10%
or 5% it boots past POST, but I get a BSOD before Windows XP can load.

Running at standard speed of 2.4Ghz there is no problem.

Anyone have any ideas on why I can no longer OC? Anyone have a similar
experience?

Thanks,
Kwake
 
Make sure the boot drive is back on the PATA.
XP sets itself up "finicky" with respect to that kind of thing.
I can switch from mobo ide to mainstream controller cards no
problem, but mess with too much and you have to do a clean install.
 
Thanks for your response Bob, are you sure that will solve it (from
experience?).

I really would like to continue using the SATA connector for my boot drive
(especially after I buy a true SATA 150mb/s SATA hard drive sometime in
November/December).

Is it a known issue that the boot drive must be on a PATA IDE connection
in order for Overclocking to work?

THanks,
Kwake
 
If this is correct then it's the first I've heard of it but it could explain
when I invoked "Turbo" mode yesterday after installing my twin SATA RAID 0
setup, why the monitor went blank and the machine rebooted. Fortuneately,
pulling the plug for 10secs and rebooting, prompted CPR to kick in and I was
restored, but why could I not invoke "Turbo" mode.

We need to hear more about this please

I'm using two SATA 150's in a non-RAID mode. A CDRW on one of the IDE
ports. I'm booting under W2K or WXP from one or the other of the SATA
drives (WXP on 0/W2K on 1). I'm running a 2.8GHz P4 at 3.1GHz. I've
had it up to 3.4GHz. No problem.

Look guys, all I was implying was that you can't expect to install
windows xp on a computer and then start rearranging the boot drive,
willy nilly and expect it to always work. It just about shit a brick
when I changed from a 1800 tbred to a 1900 palamino(stepping)
on a computer I built/loaded a while back.
There are several issues including the obvious WPA election.
I suspect tho that this problem something to do with third party
translation. When we got our first ata 66 pci promise controller, my son
moved his hard drive from onboard ide to the controller, he would freeze at
the 98se screen. The promise site finally yielded the answer, clean
install from their card.
Another possible issue, I think we are coming full circle again with
the software/hardware issue, the hardware is getting too far ahead again, MS
came up with slipstreaming and SP's to compensate,
but standard procedure last time(for us) w/ W98se was gut the box
to vid card only, turn off any onboard stuff in bios, load the
OS(W98se/W2k), load the mobo chipset drivers, vid driver and then start
adding stuff slowly and methodically.
When Wxp came out it was a relief from all that crap, I had a few via
boards/hardware combinations, that running W98se as a repair disk
hosed the boot.
I won't even try to say that Wxp belongs in the same category with
W98se, but don't expect it to be bulletproof either. MS found that
machines running W2k with SP3 and then using the original OEM as a repair
would hose the boot, hence their inclusion of the slipstream
option.
Stabs in the dark! VBG! Good Luck! I just finished loading my first
Asus/Intel/Promise mobo in over a year, it was a P4C800-E Deluxe.
It took 2 tries, these bios's are a nightmare, it would have helped if
I had read the manual or come here first.

I, too, have a similar system (2.6GHz) but am using my two SATA Raptor
drives in RAID1, not 0.
I am using two 512MB Corsair XMS memory, but only PC3200.
Everything worked great, so I thought I should be able to OC my machine
without too much trouble.

Actually, I am more interested in stability than speed, but thought
that Turbo should be ok to use.
Anyhow, I turned on Turbo and it refused to boot.
After a few anxious moments I was able to restore the bios and
everything worked again....but I certainly
will never invoke Turbo again. Just what does turbo do?

I have read that the some SATA controllers (including ICH5 based) and many
PCI bus cards are extremely sensitive to overclocking.
The advice has been to lock PCI / AGP / ? bus speeds at their design speeds.
Sometimes people overclock by droppig the memory ratio down, then increasing
only the CPU MHz .

No too sure about the P4C800 - have ony had a P4P800 which is quite
different.
