How to overclock HP 8530W elitebook?

[tilhasbb]

Hello,

I just bought the highest end HP book available for work. But I need to overclock it just a bit. Its lagging a little while doing Cad applications.

Specs
P8600 2.4Ghz
4G PC2-6400 6-6-6-18
Graphics Nvidia Quadro FX 770M
Hitachi 160G 7200RPM HD (HTS723225L9A360)

How can i overclock the processor a little?

It might be locked down by the BIOS. Your best bet is to open it up and find the PLL generator number and follow the overclocking thread by moral hazard in the hardware subforum.

You can't overclock it "a little". It is BIOS locked like all HPs. The PLL is also TME locked, and there is no relevant documentation or support for that PLL in current OC software either. You could potentially unlock TME by guessing which pin it is, and you could get lucky, but even then you may not have success with any OC software.

You also could do a hardware PLL BSEL mod, but that would give you 333MHz FSB, which is a massive overclock, and may not be stable.

Your best bet would be to upgrade the CPU. You can put pretty much any C2D socketP CPU in there and it will work. It is pretty easy to do. I have had success with a QX9200 ES CPU (Core2Quad 2.4GHz) in one. Or you could go the x9100 dual core 3.06GHz route, better still a P9900.

You can also software OC the GPU, I use ATi tool to do it in XP. That would be a good first port of call for you I reckon.

PLL is likely an ICS 9Lxxxx and tme-locked. See instructions here on how to TME-unlock the PLL. A warranty voiding exercise.

No, the PLL is a SLG8SP533V.

The datasheet can be found here. There is nothing of any worth published regarding TME - and TME is locked. Also the FSx pins need to be held at around 1v during init to get a logic high, any higher and it goes into self test mode. ie. they have made it as difficult as they can (but not impossible) to overclock with basic soldering skills.

Thanks guys.
I ordered the highest end processor for the EliteBook.
I`d rather not shell out more money but just overclock it since i realize it runs very cool I figured I can bump it up a little safely.

I`ll try GPU overclocking.

Just be careful about the GPU memory since it usually has no temperature sensors...

best bet buy new cpu , that's what i dis with my 8510, had a t-7500 went for x-9000 and it now runs fast and cooler that stock .

A P8600 is definitely not high end. The 8530w comes with anything up to a X9100 or a QX9300 from the factory, the P8600 is only one step up from the bottom of the list of available options, P8400 being the lowest on offer.

Even upgrading to a reasonably cheap T9400 would give you a good performance boost - ie. double the cache and a wee bit more clock speed.

Let us know how the GPU overclocking goes.

I tried Ntune and Rivatuner.
Both give me a bluescreen the second i hit apply?!?!

Darn HP.
I am thinking of donating this to one of the new guys and getting a DV6T with an I7 core.
