I just setup my system with the Albatron PX845PEV Pro with a 1.6A and DDR333 ram
i'm able to take the cpu up to 166FSB but I only have 1.5 and 2.66 for mem ratio...and i have the same mem ratio(1.5 and 2.66) at any speed
Am i overlooking something? or its the type of mem that i'm run?
Thank you


Fixed-> Make the CPU think that it runs at 133FSB and not 100FSB.... Read down for more info :D

I only have 1.5 and 2.66...(not 1.5 to 2.66)
if i want to run at 166FSB i have to have my mem at DDR249 or DDR441 and i don't think DDR333 can run at 441
so I'm I overlooking something?

no 4:5?

LMAO!

sowwy :(

i think you need to hack it ~ i saw a linky somewhere ~ ill see if i can find it again ;)

Heh..you can tell Albatron engineers came from Gigabyte. They have the same method of mem ratio naming
1.5 = 4:3
2.66 = 3:4
You should also have
2.5 which is 4:5

Yea me too. If I understand what is being siad, here and over in the main thread, is that because the system is detecting our CPU as having a 100Mhz bus, the only choices are the two we are seeing 1.5 and 2.66. No 2 or 2.5 unless you have a 133 chip. Apparently there is no motherboard jumper or BIOS setting to overrride the bus detection.

Maybe THUGSROOK will find a hack for it :)
I have some DRR400 come some maybe it will run at DDR441 :) I hope

If you're not seeing a 4:5 ratio at 133MHz FSB, then you're not using the latest BIOS. Go to Albatron's site for that. It's odd your board didn't ship with the latest BIOS which has 4:5 at 133MHz FSB. Not sure about 100MHz FSB, since we didn't do any testing at that speed. Myself, I'd be using a 2.26B (C1) in that board, as with most 845PE boards.

It is an older version of BIOS. Will try that quick as I get my network configured. No floppy :)

We get 4:5 ok (4:5 = 2.66) we are able to use that at any speed

I found its in the book P. 37 under DDR:CPU Ratio

DDR:CPU Ratio
This item allows you to adjust your DRAM: CPU clock Ratio. This option allows you to over-clock the system.
When CPU host frequency is set to 100 -> Options: Auto (default) - 1.50X (Debug Mode) - 2.66X - 2.5X
When CPU host frequency is set to 133 -> Options: Auto (default) - 2.00X - 2.66X(Turbo Mode) - 2.5X
Click to expand...

So..I think there something missing, At 100FSB i should be able to pick from Auto (default) - 1.50X (Debug Mode) - 2.66X - 2.5X but i only see 1.50X (Debug Mode) - 2.66X
What do you guys think?

im kinda confused by the terminology used here but...

you should only get 4:5 ratio above 132fsb ~ 1:1 and 3:4 at all fsb.

HTH :)

This mobo didn't use ratio like 4:5 or 1:1
Its like this
1.5 = 4:3
2.66 = 3:4
2.5 = 4:5
So you find the DDR speed like its
(133X2.5=333)= DDR333
(166X2.66=442)= DDR442

but the only things i can pick at any FSB is 1.5 = 4:3 and 2.66 = 3:4 and thats all...
and I'm using the newest bios (R1.5) and i'm get then samething

I see the same thing using two different 400MHz FSB CPUs, 1.5/2.66/AUTO.

What hack? A hack for the motherboard or for the CPU? Can someone verify that an "official" 533MHz FSB CPU give us the other multipliers? If so, I know the "hack" for making a 400MHz CPU into a 533MHz CPU. I figured it out when I was trying to figure out socket 370 chips and 66/100/133 mods on unoverclockable motherboards. I made a page HERE. I've tried both socket 370 mods, but *WARNING* I have not yet tried the socket 478 mod. Do at your own risk, YMMV. BTW, the socket 370 mods worked flawlessly. My friend now has a Celeron 366 running at 550 default voltage in a Shuttle SV24. I also have a Shuttle SV24, with a Celeron 800 running at 1066 (with a voltage wire wrap).

I had heard good things about Albatron's support, so I tried e-mailing them about the lack of ratios for 100Mhz buses asking if there were any work-arounds or future plans for updating the BIOS. I also asked about the temperature reporting in BIOS that shows the CPU temperature always 5-10 degrees C below the case temperature.

Albatron's response was a typical form response ("Thank you for contacting ..."). Attached to the email was the rather lame "How to Overclock" pdf file available on their website.

My Albatron is going back.

thats really bad... :(
Well I really like the mobo and i think I'll keep it for the time beening
the only think that holeing me back for running my 1.6A at 166FSB is my ram :(

THUGSROOK -
Well I'm able to take it up to 166FSB but only using 1.5 for the mem ratio and using DDR 249 really not that great :p

i dont understand...
you need 1.675v @ 156fsb and @ 166fsb?
that dont make sense :confused:

either lower your voltage @ 156fsb or in reality your 166fsb aint stable.
you cant go 10fsb and not raise voltage :confused:

I don't know if i NEED 1.675 at 156fsb that what i'm testing for right now, but with 1.70 I can ran 3DMark2001 SE and Sandra at 166fsb but I have not really test with Prime95 because I really don't want to use DDR 249 but if i had mem ratio of 2.5 then i could have DDR 415...but i need to wait for a fix of a hack :disgust:

but overall i really like its mobo... I have not seen any cold boots issue yet but i have had my computer off for that long
is there a good why to test for cold boots?
