P-7908u FX - upgrading CPU

[slightlyhuman]

Thinking of picking one of these up. Was wondering what CPUs I could upgrade it to?

Was looking at this one:

eBay - New & used electronics, cars, apparel, collectibles, sporting goods & more at low prices


I'd really like to put a quad core in it but am unsure about the cooling being efficient enough:

Newegg.com - Intel Core 2 Quad Q9000 Penryn 2.0GHz Socket P 45W Quad-Core Mobile Processor Model BX80581Q9000

Other upgrades I'm going to do is throw an SSD in there? Also, does it have two bays for HDs? Hoping to have a regular SATA in there for backup and use the SSD for my OS and a few games.

Also upping from 4gb to 8gb.

Can any one chime in on all of my questions or some of them?


Thanks! Been a lurker for a while.

If you have noticed the quads do not work well in these. Unless you specifically need, and can ultilize, a quad core then you are better off with a x9100.

Yes there are 2 bays and SSD is a great upgrade.

Unless you specifically need 8gb I wouldn't bother..................

thanks for the reply! you know your stuff(been following your posts). i only want to play a little bit of bf3 and know the game utilizes quad cores. when you say work well, as in heating issues or what?

The Q9xxx uses way more TPD than the C2D. Actually it is proven in 4 thread opperation the 2 cores of the CQD loose efficiency per clock over the C2D. This is 10-20% loss.

So a CQD at 2.0 GHz is 10-20% less efficient than a C2D at 4.0 GHz. At 20% you only need a x9100 at about 3.2 GHz to equal in all tasks a q9000 and at most tasks the x9100 will smoke the q9000. Also the cooling solution stinks on our system for CQD's and even the stock q9000 will throttle often without undervolting under full load.

Now quad iCores are another story as they natively allow for thread affinity per core rather than load sharing and of course the core is faster even in single thread per clock......................

What about an e8235? It's 2.8ghz but has 6mb cache at only half the press of the x9100. I'm mainly looking to get the best performance I can out of bf3 that I can from this machine.

Not sure about thee game and CPU power. The e series should work though.......

Well am I missing anything in the 200mhz or so being the only difference in those two chips? If you think the extra 200mhz will make a difference then I'm all for it. Not worried about the money, just want to get the best I can inside the lappy. But not if i won't see a difference. Thanks for your replies. You know your

Again I am not surre of the load your game will take. Remember though a x9100 can over clock a bit too. So if you plan to keep it a while this will future proof it a bit more. I am not saying tthough the non xtreme CPU will not cary you though as you may never need more.

All I can say is the conservative 3.4 GHZ I used to run was just awesome at just about every thing. Snappy as all get out and enough umph to plow through walls. I fell into the hype with the quad core. I don't regret running it as it is a tank and I don't require a sports car.

I can tell you for desktop usage you could feel a difference up to 3.2 GHz. After that point the returns seemed minimal and were more just to see the benchmarks. So you will see and feel the difference between the 2.8 and overclocked 3.2 GHz. Again in game I am not too sure.

Going from 4GB to 6GB is more noticeable than from 4GB to 8GB. I noticed that second jump was more just for my own OCD more than anything.

It'll let your overall experience in games go a bit more smoothly to update the RAM, add in a SSD, and update the CPU a bit more. It'll round your machine out for a while longer.

If you do go for a SSD, get a 120GB model at the dead minimum. This'll allow you to install a game or two onto it and experience those games a bit more effectively. I play World of Tanks, and beforehand I could barely manage 25-30FPS on high settings. Now with the Vertex 2, I manage 35-50FPS on average with the same settings.

Not to mention it's VERY satisfying to know you can turn on your machine, log in, log off, and restart your machine in the same time it takes just to load on your old HDD.

I say the best deal I can grab for a laptop that won't be harmed by the Sandforce drivers would have to be the OCZ Vertex 2. This drive just makes my day. The CPU is coming up next for this machine...

just installed my intel 320 80gb i got for $79 after rebate! Also got the 2.8ghz dual core i bought for $40. SLAQB stepping


cpu upgrade today or tomorrow. also, been out of the GPU OC'ing scene for a few years. what's a good utility and what speeds are users getting with the 260m?
