help, multiplier locked on 12 while should be on 23 (p4 s478 3.06ghz)

[snowdog]

Hi , im a pc builedr and recently bought a 3.06 ghz cpu (not 1ts one, often buying em), but as the title says this is the prob: multiplier is locked on 12 while should be on 23 (p4 s478 3.06ghz), tried it on both asus and msi mobo's, asus says its the rigth cpu (also says 3.06 on cpu itself)but multiplier seems to be locked @ 12 and its runnign at 1600 mhz instead of 3060mhz, (its a northwood core btw) so anyone know what i should do (ps, the cpu seems to be from a laptop, tho i dont know why that would make a difference)

So anyone pls help and if you know how to solve this pls say so

Thanks in advance, sry if i made some language mistakes, eng isnt my 1st language...

If it's from a laptop thats why. Due to speedstep, it's locking at the lowest multiplier that speedstep would take it to. This'll be an issue for several boards. Not sure which would work properly.

im pretty shure theres no easy work around - youll just have to up the fsb

 

[stigggeh]

edit read wrong... yes its sounds like a mobile cpu to me.

if your board can take it, the only thing to do is put the memory on a 166 divider and turn the fsb up to 250

Try setting the power options to always on.

Cpu-z recognizes it as a normall p4 3.06 ghz northwood, as does the mobo, k ill try upping the fsb to 250 and just let ram work 5:4 with cpu.
Thhx for reply's, never heard of laptop versions with lower locked multipliers tho but anyway thanks.

Im open to any suggestions still tho that may unlock the multiplier somehow.

its just something that seems to happen, its a common problem, laptop northwoods in a desktop board = 12 multi, dont ask why because i dont know....

It's not that the multiplier is locked, it's that your board doesn't support speedstep correctly.

On a mobile P4 chip, the bios can adjust the multiplier on the fly to reduce power consumption, because doing this slows the chip down without altering anything that affects any other componants (unlike dynamically adjusting the FSB)

If your board doesn't support this, it defaults to the lowest multiplier. You could try updating your motherboard bios and see if that resolves it. these chips, with boards that support them, are actually highly prized because you can tweak multiplier/fsb settings to get maximum performance.

there also some of the best cores

Thanks, cant find much info about speedstep for my mbobo's but atm with the old bios i know that my MSI 865PE NEO2 and ASUS P4P8x dont use speedstep correctly, ill try it on my P4c800 Deluxe later (cos it has latest bios)

It'll work at a multiplier of 12x in any desktop motherboard - not much can be done about it. It's going to take a 255MHz FSB to get to 3.06GHz Shouldn't be much of a problem in a board that supports an 800FSB with DDR400 RAM - you can use the 5:4 memory ratio to keep the RAM at DDR400 spec.

hmm k, just i have a stupid situation atm that i cant select 5:4 on my current asus p4p8x, , my c800 can so ill try tomorrow, just a bit annoying as i want to build the pc for sale and people dont want to hear about messing with multipliers/ fsb or anything that has to do with overclocking ( cant do much about it dutch are that way unfortunatly, most anyway, migth keep the cpu myself but dont want to as for example my current cpu i am using myself (3.4 prescott s478) has lowered multiplier from 17 to 14 x as my mobo allows me that so i dont know why i'd get a northwood with a bit lower multiuplier as prescotts can go upto 3.9 ghz and norths only upto 3.6 max when overclocking..., so all together max fsb will be higher on my scott than on the north

You can bend a pin on the CPU to force it to 200 FSB which makes it default to 12 x 200 = 2.4Ghz. Google for info on it if you're interested. I've done it and it works fine and gives access to all the memory dividers. If you do decide to bend the pin make sure you issolate the correct one as you only really get one chance at it seeing as they are so fragile.

When I say bend a pin I mean bend it so it's flat so it doesn't go into the CPU socket.

Also you'll need to know before hand that it's stable at 2.4Ghz but most mobile P4 CPUs should be especially the C1 steppings.

hrm, no need to bend it just coat it in non conducting paint gloss or something similar ?

I've read that works too so yeah that's a good tip which can easily be reversed.
