Hey.
I need some advice here...
Heres my setup at default:
P4 2,8 GHz HT 800MHz (14x200)
Asus P4C800-E Deluxe
OCZ 4000 Gold Dual 512MBx2 (2,5-4-4-8-4)
520W High quality power supply...
CPU temperature @36C idle / 41C 100%load
North-/South-bridge is cooled with copper sinks and 40mm fans
AMI Bios updated with Asus EZ Bios updater
Everything is stable, Prime95 ran for 7 hours along with Seti@home...
Memtest+ ran all tests 4 times, no errors...
Long story short, everything works AOK...
Then I start fiddling with Bios.. This Bios is new to me....
I gradually rise FSB towards 250 running tests and benchmarks.
Everything is dandy, but when I reach 250 the system reboots
after 7 minutes running Prime95 or PCMark04.
What can it be?
CPU voltage is on 1,7V
VDimm is at 2,85 (wich is the maximum this Bios will allow)
If I set RAM SPD on auto it runs at pc166 333 MHz.. I set it
to Manual and choose between 266, 333 and 400... I want 500!!!
I set it on 400 and now Memtest+ shows RAM at 500MHz... Strange...
But the fact remains, its not stable... I think the VDimm is to low at
2,85. It should be at 3,00V...
There's lots of other options I dont know anything about like:
Under Jumperfree settings in Bios theres a tab called "Performance Mode"
wich is set to Auto. Should this be changed? I can choose Auto, Standard
and Turbo...
Under Chipset theres "Performance Acceleration Mode" set to Auto
- DRAM Idle Timer set to Auto
- DRAM Refresh Rate set to Auto
What should I do? Is it the V on the ram? If so, do I have to change the
motherboard?
This is frustrating...
By the way, "Graphics Apperture Size" is set to 128MB. Is the apperture the
same as the Graphic cards RAM? I have a Sapphire Radeon 9800Pro 128...
Whats "ICH Delayed Transaction"?

You may have reached the max that CPU is capable of. Most 2.8s (most
assuredly not all) that I've seen numbers on max out around 245fsb, give or
take a couple of points. If your CPU is capable of more 1.7v might be too
much. Or you might consider extreme cooling for your cpu like phase change
or a pelt.

Ill try lowering it...
Most people I've read about has reached 3,6+...The CPU never
exceeds 43C acording to Motherboard Monitor... Its a very well-cooled
system considering its air cooled...

Water is my next project, phase will have to wait. Never liked peltier's...

It's just the "luck of the draw". I've seen some 3.6s and I've seen some 3.7
& 3.8. The 2.8 that I have in another rig won't do over 3.4 no matter what I
do to it. You never know 'til you jump in and try. With 4000 mem, I really
doubt you are pushing the limit of your mem. So it prolly is an issue of
balancing the fsb with the Vcore until you get the most out of the cpu. You
will hit a point with air cooling where it doesn't matter how much Vcore you
apply, the cpu just won't go any more. You can also apply too much Vcore
where the internal heat it creates keeps the cpu from working properly..

I pushed the Vcore up to 1,8V and its rock stable!
Spec:
P4 2,8@3,5 (14x250) 1,80VCore
Ram @ 1:1 DDR500 Cas2,5 2,85V
CPU Temp @34C idle @45C full load
Case Temp @28C idle @30C full load
Its not even loud...

Ever hear of "Sudden Northwood P4 death syndrome" .

Dude that WAY to high a voltage for your P4 (you shouldn't go past 1.7
V), And remember settting 1.7V in BIOS is actually ~1.725-1.75V at
idle already (Asus overvolts all their P4-C800 boards ~ .25 - .5V ).
My P4 3.0c cpu will only do up to 3.69Ghz rock stable at 1.65V
(246FSB), but I'd rather leave it there than push it past 1.7V!
