Anyone local want to do the pinmod for me?

The pinmod doesn't work on the 855 type motherboards. You're already running at the maximum speed that your mobo's FSB can support. 915's running CPUs that are at a 400mhz (333mhz ram) CPU instead of a 533mhz )400mhz ram) are the only ones that can make use of the pinmod.

However you can get Celeron M's on eBay for a fairly low price. But personally I'm waiting untill the Pentium M's are more down in price as used parts to upgrade my CM 1.3 to a PM 2.0+

So in order to run the pin mod. I need a:
915 Motherboard.
DDR2-667 Ram (333mhz ram)
Pentium M running a 400 MHz bus.

Please tell us how you know 333mhz ram works.

No, see, your clockspeed is a result of two numbers. The multiplyer and front side bus speed. In the case of my i600m, it's Celeron M 1.3ghz CPU has a multiplyer of 13 and the FSB is 100mhz (400mhz since it's quad pumped, but 100mhz and 400mhz are sorta, both accurate answers). Anyway, 13x100=1300mhz

While you can't increase the multiplyer you can increase the FSB in some cases, this is the most common way to overclock. So to increase the FSB from 100mhz to 133mhz (533mhz) via the pinmod the math becomes 13x133= 1729mhz. Bam. You're going over 500mhz faster.

However the 855 family of chipsets do not support FSB speeds over 100mhz/400mhz. So to overclock it would require pushing it to a level the motherboard can't do. It would either refuse to boot or try to go that fast and probably damage itself. But I'm pretty sure it'd just not boot.

The 915 family however supports 133mhz/533mhz FSB speeds that the 855 family doesn't. But this requires a CPU that has a 100mhz/400mhz FSB to use the pinmod. Basicly, you can't overclock your laptop. It's just not happening.

As for the Pentium M, no you don't need that, the pinmod works on either chips, Celeron or Pentium. I was just suggesting that you UPGRADE instead of overclock.

There's a person who can't pinmod.
He's using a Inspiron 1300, with a 915 Motherboard, 533 (266 MHz) PC4200 ram, and a 400 MHz Pentium M cpu.

You said that using ram that's the speed he's using won't work.
But DDR2-667 Ram (333mhz ram) will.

How do you know 333mhz ram works ?
Please tell us.

From what I can tell, the B130 uses an Intel 910GML chipset which unlike hte 915's only supports 400mhz on the FSB. No, I didn't say his RAM won't work. I said his entire motherboard won't work with it. For the pinmod to work you need 333mhz memory and a mobo capable of a 533mhz FSB.

I beg to differ... As I have a pin modded b130 and yes the fsb is running @ 533MHz, but I'm sure that the motherboard may cause a "bottle neck" because of the 400MHz FSB, but I still get the 2.26 speed...

I'm curious what your board is doing. The ratio between the FSB and the RAM should be 3:4. Under normal circumstances, 100mhz(quadpumped to 400mhz):133mhz (DDR, thusly 233mhz)... So... The pinmod should result in 133mhz(Quad pumped to 533mhz):166mhz(DDR, so 333mhz)... So... I'm curious to see the speed of your FSB and DRAM.

I would also like to mention that the asynchronous nature of the FSB and DRAM in these things makes my head hurt.

Cause if you can do it on a 910 (Assuming Intel's site stating it only supports 400mhz FSB mode is acurate) I'd be curious if it can be done on an 855 type board. Since I've always been told it simply can't.

It can be either the 915 or 910 Motherboard.

By chance you got the 915. So the pin mod could work.

There have been quite a few other posts in the dell forums recently of people of have gotten that B130 laptop if I recall. Look back in the last few days of posts and ask those people.

Yeah. Someone explain to me what's going on. AFAIK the pinmod basicly just ups the speed of the FSB and memory so the resulting clock speed is higher. But Intel's site says the 910's FSB speed is 400mhz, not 533mhz. So how is the pin mod working on a 910? Is it increasing the MEMORY speed but not the FSB? Is it just pushing the FSB to 533, making the entire BOARD over clocked? Can the 910 unoffically do 533 but it's not in the specs? Are intel's specs just WRONG?

It increases clock speed...

It increases clock speed pf the cpu, but only if your MB supports 533MHz FSB.

You take a CPU that normaly runs at 400MHz FSB, and by connecting some pins, you make the MB think the CPU should run at 533MHz FSB. Since the multiplier is the same, your CPU runs faster by 133* your multiplier MHz.

Pinmodding has nothing to do with memory, it doesn't affect your memory, nor does your memory affect yuor possibility of pinmodding. Cpu and Memory FSB don't have to be the same, as someone already mentioned.

If your MB supportes 533 FSB, you can pinmod. Good indicator for this is your memory. If you have memory that runs at 533MHz, you can probably pinmod.

The clock speed is just DRAM Speed X Multiplyer. It can't just 'increase the clock speed'. It increases the memory speed and so the clock speed is increased as a result.

Anyway, as said above, if you're motherboard supports an FSB of 533mhz. Intel says the 910's only support 400mhz, yet people are having success with the pinmod, so what's the deal?

Cpu-Z shows the motherboard chipset to be a 915GM/910GML...

Be sure your memory can run at 533mhz. If not, odds are you wont post. You can check your memoy speed in cpu-z. You will need plenty of light, tweezers, magnifing glass, and a very steady hand. Use the url I posted earlier. GL
