What about MPI? I have an MPI with a celeron 2.8 prescott socket 775 with 1x512 DDR3200 ram I have looked everywhere to try and over clock this system. But to no avail...... Is there anyone out there with the knowhow to help me over clock this thing??????

nice guide

if it isnt in ur Bios then chances are no..but if yuo can download clockgen..you may be able to overclock it slightly

funny...

my mobo lets my timeings go to 3-4-4-10

and is it possible that raiseing vcore makes your system more unstable?

NoAffinity

Yes, it's possible. If the CPU can't handle the given voltage at the operating temps the voltage produces, then operation will become unstable.

so is 1.42 @ under55c to much?

NoAffinity

You wouldn't think so, but every chip is different, and all chips have thier own overclock/voltage/heat tolerance limitations. Some reach their limit earliet than ohters.

Hey guys, i just read this guide and started overclocking my cpu. I had a question about the final results and roughly what they should be about. Lemme get this straight:

cpu - upper range (as long as its stable)
vcore - upper range that is possible without burning something
ram latency - tight as possible (generally want a tight ram)
ram speed - high as possible (generally want a ram speed equal to cpu speed)

if that's correct, then i wanted to ask is it better for the rig to have a [tighter ram and a lower speed] than a [lower ram and higher speed] or somewhere in between. Or is it that i want a high ram latency and a high speed to match it? I guess i'm just tryin' to figure if i should increase the ram latency.

i'm using:
cpu external frequency: 200/33 overclocked 255/43
memory frequency: increased to 424 (from an auto setting)
cas latency: 3T
ras to cas relay: 4T
ras precharge time: increased to 4T (from 3T)
ras active time: 7T
vcore: (unadjusted) 1.5250

am i doing this right? where do i have some headroom?

If you're on an Intel system, higher overall FSB will benefit you more than tighter timings (see RAM guide in sig for more details). If your on AMD, tighter timings are more beneficial. You overclocked to 255 mhz FSB without increasing vcore? That is extremely impressive. Based on your RAM speed, which doesn't appear to be completely accurate (unless the DDR424 was taken from different operational settings than what you listed for the CPU), 'auto' is producing a 5:4 CPU:RAM divider, which would put RAM speed at DDR408 w/ your CPU at 255 mhz FSB.

What are your load temps at 255 mhz FSB?

Wow 255mhz on stock is impressive. It does look like "Auto" is messing up your RAM speed.

Btw, Long time no see, NoAffinity
