mobile athlon 2400 in msi k7n2gm-l

[merk]

this is turning into one of those system builds from hell. I should have stuck with a desktop cpu.

anyhow, i had a chaintech board which did not allow me to set the cpu settings, and it was running the cpu at 800mhz.

So i returned that board for an msi board which is supposed to allow you to change the fsb, multiplier, voltage etc. there's nothing i can see in the bios to let you do that. i downloaded their window app, fuzzy logic, which is supposed to let you change all that from within windows.

When i run that program it shows the current settings but it wont let me change anything. also for some reason it says the cpu fan speed is 0, even though if i go in the bios it shows the fan speed at around 5k.

can anyone tell me if i can get this cpu working at close to its normal speeds? someone pointed me to the pin mod hack... but i think i actually have to cut something on the board to get that to work and i'd rather not do that since i've never modded a motherboard before. if i just have to cross a few pins on the cpu i'm willing to try that.

although ideally it would be much nicer if it would just work through the bios or through the fuzzy logic app.

anyone have any suggestions as to why its not working?

right now i have the cpu ay 800mhz with a 133fsb and 6x multiplier.

thanks for any help

The only difference between a Mobile and a Desktop cpu is if the
chip runs at 1.46 vcore, it is used in a mobile. If not, it gets a Desktop tag.

But, not all CPU's are created equal (your mileage may vary).

What Brand/Type memory are you using?

How do you have the MEMORY TIMINGS and VOLTAGE set?
Should be optimal and DDR Voltage@ 1.6

The mobile chips are finicky what clocks and FSBs they'll run at on particular mobos. I'd get a known overclocker board and use that. Also, desktop mobos don't have full support for mobile chips. For example, the 2600 mobile I have is supposed to run at 15x166, but it'll only run at 12.5 multipliers and below, although I can run the FSB at 200 or more, since the chip is unlocked.

well i wouldnt mind if the chip was running a little bit slower then what its supposed to run at. but right now its running at less then half. The most i've gotten it to run at is 800mhz if i bump the fsb up to 133. Although it failed to boot once when i did that.

I'm not sure of the particular brand of memory ... i think it was toshiba and its running at 333.

Right now the memory is set to auto or spd i forget which. the voltage defaulted to 1.6, and i can change that in the bios to 1.5, 1.7 or auto.

i've tried setting various combinations in the bios of auto and spd.

the thing i dont understand is this board is supposed to let me set the multiplier, voltage etc, and its not letting me. thats the whole reason i picked up this board was because i thought i could set all those options. but the program msi provides to do this wont let me change anything.

I just downloaded your mobo's manual. If you look on page 3-12 it has BIOS settings under Advanced Chipset Features. Can you set your CPU FSB Clock here to 200?

I also suggest you search and/or inquire here.

yeah i should be able to set the fsb in the bios, but that still going to give me a slow system. It'll only be running at 1.2ghz, correct? I thought the correct setting for this system would be:

fsb 133
multiplier 13.5
voltage 1.45 or 1.55

I'll try changing the fsb to 200 if you think it will help.

thanks for the advice

i just bumped it up to 200 ... had to set it to manual since it didnt give me 200 as a choice under auto, just 100, 133, and 166.

its running at 1.2ghz right now. There's also another problem which i dont know if it might be related in some way ... my mouse is very jerky. Its like there is a huge lag between moving the mouse and seeing it move on the screen. I'm using a wireless mouse, so i thought maybe it was just bad reception. By the mouse is 1-2 feet from the reciever and the wireless keyboard seems to work fine. Just mentioning it in case it might give some clue as to whats going on.

i also tried running the fuzzy logic app while the system was set to 200fsb but it still wont let me change anything and still says the fan is at 0 rpms

thanks again for the help

well the mouse problem cleared up on its own some how. I was typing my previous reply on my laptop ... when i came back to the problem machine, mouse was ok.

well i am pissed, this is what msi just emailed me back on this:

All Nvidia based mb does not support Fuzzy Logic utility. All Micro-ATX mb does not have any selection to change CPU Multiplier/Voltage/FSB. Only Standard ATX boards does.

looks like i screwed myself twice in a row with this system. I think at this point i'm just going to get a desktop cpu unless someone knows of some magic to get this machine working correctly.

 

[huesmann]

Well, 1200MHz is better than 600MHz.

Did you ask MSI whether there is a way for you to set the multiplier manually in the BIOS as you are able to do for the FSB?

 

[merk]

theres nothing in the bios to set the multiplier. I may try the pin mod hack and see if that'll work. The mobile cpu seems to run cooler then the regular desktop cpu but that was also at the lower speed.

The mobile Bartons are actually set to run at a lower FSB (mobile chipsets are clocked at 133 MHz while a comparable desktop Barton is 166 MHz).

There is a slight difference between the two chips. I would assume that the Chaintech mobo wasn't designed to recognize the mobile proc and thus the problem.

BTW, I"m experiencing the *exact* same problem with the Chaintech 7NIF2 and Mobile 2400+ right now

well, i tried doing the pin mod to get it working. I had it working at 2200mhz with an fsb of 166 using the pin mod ... although i was aiming for 1800mhz ... so when i saw it was overclocked i went into the bios and lowered it to 133 ... and that was the last time the thing booted. I dont know what the hell i did, but i screwed something up good. I cant get the board to boot up at all now using either a mobile or desktop cpu. even undoing the pin mod it still wouldnt boot. I'm really ticked ... would have been very cool getting it working with the mobile cpu... could have had a much quieter machine.

if i can return the mobo i'm just going to put the desktop cpu in it and be done with it.
