i have a albatron PE865PX mobo with a 2.4c and 2x256 3500 hyper x
i had it at 3.2 with the help of fredtam, a excellent member on these forums


ive reset my bios and need some help remembering what to do and what to put to what in the bios to o/c again.

IM ONLY WANTING TO GET 2.8 FOR NOW
in my bios I have a DDR:CPU Ratio menu, I can either put it to:

1.33x
1.60x
2.00x
2.50x(turbo)
2.66x(turbo)
Default

what do I put this to?

I also have the cpu voltage menu what should I put it to? I have:

Default +0.3V
Default +0.2V
Default +0.1V
Default

what should I set it too?(i have stock cooling) but good air flow



one more menu is the DDR Voltage menu, what I set it to? I have :

Default +0.3V
Default +0.2V
Default +0.1V
Default



please tell/help me on what to set these two? I can take care of the FSB



thx

Flattery will get you nowhere. Sorry man I wasn't ignoring you I just forget to check my PMs. I never heard back from you the last time. Give me a second to look over your options and I'll post back.

I'll try to help, but I'm not familiar with that particular board....

first the ddr/cpu ratio, I assume that "2.00x" equates to 1:1, if so, you probably won't be able to run that at 234fsb to hit 2.8. I'd try setting it to 1.60x (which I assume is 5:4) you should be able to run tight timings with that setting.

as far as the voltages are concerned..... start out with them at default, if you need more to reach your goal, up them one step at a time and retry.


Hope this helps..:)

what causes that error when overclocking?

Ok Sorry I was working
First lock the PCI/AGP Bus
Set the FSB to 233
Set the mem ratio to 1.6X
Bump the mem voltage to +2v
You should be OK without a CPU voltage bump.
With an even higher DDR voltage you may be able to bump the memory ratio to 2X or 466Mhz.

The main thing you have to remember with that board is the odd memory ratios.
To figure out what speed your memory is running at multiply the FSB by the numbers fiven ie. 1.33,1.6,2 etc.

Right now you have.
233 x 1.6 = 372MHz. This is actually slower than your memory spec. Unfortunately the next multiplier is 2.0.

233 x 2.0 = 466Mhz which is obove the rated speed for your memory.
To get the full potential you have two options:

1. Raise the FSB to 270 (3.24Ghz)which would run the memory at its rated speed We already know your CPU will do over 3.2.
.
2. Increase the multiplier to 2.0 which would run the memory over its rated speed at 466MHz. This would require a memory voltage jump but I have no doubt your memory will OC that high.

Right now your somewhat crippled because even though your CPU speed is high your memory is below spec. Don't let that scare you though because for most apps. it will be faster than the stock setup.

I know I sent you this in a PM but I figured I would post it here so you can reference this thread in the future. Again any questions PM me.
