p4 mobile not responding

Specs: Windows XP, 2.8ghz/2gb ram
hey guys,

I've set up a system for someone last week, as follows:

Pc Chips M952 mobo, and a p4 mobile cpu SL726 (Intel Mobile Pentium 4 3.067 / 1.6 GHz). Upon boot, the POST showed me that it recognized the cpu, it showed it as a 3.06ghz cpu running at 1.5ghz. POST actually displayed p4 at 1.5ghz and underneath it displayed (3.06ghz cpu). So I figured it's fine since the bios knows what cpu it has. Furthermore, I figured that after xp gets installed, it will know when needed to rev up the cpu to its full power. so the guy installed xp at his place, and then tried installing a game that requires a 2.0ghz cpu. and the game installer said it can't install, due to cpu limitation. he's bringing the mobo+cpu over in an hour, for me to help fix the problem. Where do I start?

I always say it's best to doublecheck.

this is the manual download link http://www.pcchipsusa.com/PCCWebSit... for the mobo. please someone get it and look at page 12, where the jumper settings are.


then from page 23-24, the bios options are shown and I could use some help there too I think.

Remember what I told you about running a laptop CPU in a desktop machine? The BIOS will NOT properly recognize the CPU because laptop CPU data is NOT contained in the BIOS. The CPU settings MUST be manually configured. And as I also explained, the BIOS will automatically select the lowest CPU multipler the board supports...if there is no multi adjustment in the BIOS, you're stuck at that setting.

Just to add, this has nothing to do with Windows, it's entirely a BIOS configuration problem. And you've been posting here long enough to know that we need to know the specs to be able to make any recommendations. Where the RAM?

okay. i have a 256mb ram stick in the system. i went into bios and found the multiplier, but it says LOCKED. aren't these cpu's supposed to be unlocked ? or should i mess with the fsb jumpers, jam ?

I just had a look at the manual. You sure do have a thing for crappy VIA based boards...lol. Setup the CPU to run at 3.0GHz (15 x 200MHz). To enable 200MHz (800MHz FSB) set the jumpers to:

JP2 = Short Pins 2-3
JP3 = Short Pins 1-2

Hopefully you have DDR400?

yes, it's ddr400, doing the jumpers now.

damn i love you :)

it runs at 2.4 now. but the bios still says 'locked' by the multiplier setting. funny thing is, when i try a celeron, it's no longer locked. now should i use those options on page 29, to reach a higher frequency ? how high u think i can go? i can increase fsb by increments of 1

IMO, there's not much point running the CPU frequency higher than 200MHz. You can if you want to, but the DDR400 is already bottlenecking the system. P4's perform best with a CPU:DRAM ratio of either 3:4 or 4:5, depending on the configuration. Right now, you're running 1:1. If you start raising the CPU freq even higher, you'll bottleneck the system even more.

well, i've gone up to 216 on the fsb, and it's showing me 2.6ghz now. thing is, i think the owner has stronger (faster) ram. I'm calling him now to doublecheck.

"i think the owner has stronger (faster) ram"

I highly doubt it. The board only supports up to DDR400...you'd need DDR2-533. What speed is the RAM running at with the CPU freq at 216MHz?

i don't know what speed the ram is running at, but i've seen an option under dram to set it to -66 or -33 of the cpu clock. that's backwards though, right? i had it up to 2.66ghz (the cpu), but i felt it slop. like after saving bios changes it would hang and I'd have to power off then back on in order to boot.

"had it up to 2.66ghz (the cpu), but i felt it slop"

Assuming the RAM bus is increasing as you raise the CPU freq, you most likely reached the limits of the RAM. Are you able to lock the PCI/AGP? Try setting the RAM to -33 then continue raising the CPU freq.

jam, i did try at -33 and then at -66, but as soon as I go past 2.5ghz total for the cpu, although post is fine, win xp will start saying crap like "ntdlr is missing" so that's the peak of our overclock. because what we did here is overclock thru fsb. unluckily, the multiplier stays locked. i guess 2.5ghz on this p4 (tempersture stays at 27C during benchmarks) is a great thing, compared to a celeron 2.6 or 2.8, or a regular p4 running at 2.8, which would go above 40C. am I right ? btw vcore never went above 1.2v

DRAM bank interleave bios option has 3 options: disabled, 2way, 4way. help me figure out what that does? and since you know the way i have it all set up, which would be the best choice?
btw i've set the CAS to 2. it was on 2.5 by default.
