Missing mem ratio on Albatron PX845PEV Pro--->Fixed! :D

[scdill]

Is the missing ratios at 100Mhz an Albatron thing, or is it an 845PE "feature"? If its an 845PE feature, do other manufacturer's allow the manual selection of 400/533 (Albatron does not) as a work around?

i think its just a Albatron PX845PEV thing but i'm not sure...this is the only 845PE mobo that i have used

 

[THUGSROOK]

the Abit BE7 and Asus P4PE have both ratios at all FSB.

THUGSROOK -
Did you find that the Abit BE7 was under volting?
It looks like the Albatron PX845PEV Pro under volt by .02 to .04 volt

No 1:1 ratio? Should have one since if you use 266 memory with a 133fsb processor you would need it. Then when you run the fsb at 166 the memory can be 333. I have a feeling that using auto at 133mhz or above is the 1:1 ratio. Since the 2.5 setting is for 333 when the fsb is 133.

 

[PhoenixOfWater]

if you are using 133fsb processor you get all the mem ratio but if you are using 100fsb processor you are missing 1:1 and 4:5

I thought all boards were like that. 4:5, 4:3,and 1:1 available at 133+. 3:4 and 1:1 at 100mhz. My board has a setting to change whether it's a 100mhz or 133mhz cpu. I set it for 133mhz cpu even though it's a 1.6A.

There is always 1:1. I think it is the auto setting. Albatron and Gigabytes ratios are a little different than the norm

1.5 = 4:3
2.0 = 1:1 (or auto?)
2.5 = 4:5
2.66 = 3:4

yes it undervolted ~ but its v-regulation system was great, only dropped .02-.03v under load :Q

still the cold boot issues pissed me off :disgust:

when i use auto it give me 2.66

THUGSROOK -
is there a good way to test for a cold boot ?

Interesting. Maybe it looks at your ram SPD and determines if it can run 3:4 @ 100 FSB? I'd rather just have manual control like Asus and Abit have.

 

[PhoenixOfWater]

i just want to be able to pick 2.5... my ram not liking anything higher then DDR420

 

[Viper96720]

Something must be wrong then. Manual says when cpu host frequency(fsb) is set to 133 you can choose auto,2.0, 2.5, 2.66(turbo mode)
If you got the host frequency at 100 then you would have auto 1.5 and 2.66. Which is what it looks like you got. It sucks that you can't set the host frequency at 133 and get the dividers you need. Still stuck with the 100mhz dividers. Albatron needs to fix the bios. So if your fsb is 133 you get the right dividers. Instead of detecting if the cpu is a 100 or 133.

 

[PhoenixOfWater]

i hope they fix this with the next bios update

Here's something to try... do a pin mod to your P4 so that the motherboard thinks it is "officially" a 533MHz FSB CPU.

My Albatron 845G board is the same way, now the Epox boards have a jumper to force 133fsb and then you have 4:5 divider in bios. If i set the Epox board to auto detect the cpu and the cpu is a 100fsb chip i only have the 3:4. The 1:1 and 4:3 are available all the time

yeah that looks like it would work but I don't feel like cutting can pins to do it

 

[PhoenixOfWater]

Zap - jspark from the overclockers Forum tryed the pin mod with nail polish and he geting not boot and after he removed polish it boot fine

Strange... should work, but I've never actually tried it. I tried nail polish on socket 370 CPUs (the Tualatin on BX) and didn't have any luck, so ended up breaking pins, which worked. Dunno. Maybe I'll try it with a Celeron 2.0, not too expensive to sacrifice.

 

[PhoenixOfWater]

yeah...if we can find a fix for this..it be really cool!!

 

[PhoenixOfWater]

any luck?

the pin trick worked 😀 jspark from the overclockers Forum just redid the trick and saids it works...he haven't reply with anymore info 🙂

Edit - He reply with more info 😀

How come this board doesn't have 1:1 memory ratio?

I oced 1.8a and memory automatically set up at 354. I can't oc more because of PC2100 memory I have.

Did you read any of the other posting in this thread?!?!?
