My MOBO supports Pentium D(Smithfield) up to 3.2 which is the 840. Questions =
Intel lists 2 of them @ 90nm. Both identical except for the technology. One being AO and the other being BO. I'm lost here. I will post links for all 3 CPUs
1) My existing 630 - http://processorfinder.intel.com/details.aspx?sSpec=SL8Q7
2)840#1 A0 - http://processorfinder.intel.com/details.aspx?sSpec=SL88R
3)840#2 B0 - http://processorfinder.intel.com/details.aspx?sSpec=SL8CM
I hope I didn't make this too complicated but I'd really appreciate all the help and input I can get before shelling out the cash. This will be my first CPU upgrade. I've already upped my VID card and my PSU. I'm Thinkin dual core will help me allot. The 630 I have now is basically useless on multi-tasks which I do allot of. Not to mention some pretty serious gaming.
Thanks again for all your help,Much appreciated.

The A0, B0 scheme defines the version or the stepping of the processor. B0 is a later stepping that fixed problems or improved the original processor. If you can choose, pick B0.

The Pentium D is the hottest desktop processor ever made and it will need a decent power supply to run. If you can afford it, get a new mainboard and a Core 2. If that is impossible, get a Pentium D 9xx series. They are cooler and less power hungry. If you can get the Pentium D 840 for cheap or lack the money to upgrade or just want that processor, go ahead, but get a good cooling solution and check your power supply.

Thanks for the info.Now which is better a 935DO(4MB cache) or a 940C1(4MB 2x2) and also the mfg on the 9s is 65nms and my present 630 is 90nm does this make a diff.???
Again my specs. say I'm maxed out @3.2 Gs
so these would be my only 2 options I guess.
Thanks. Much appreciated.
Also what is a ATX form factor ??? the 940 has ATX the935 doesn't

Here is my recommendation:

GIGABYTE GA-P31-S3G LGA 775 Intel P31 ATX Intel Motherboard - Retail $68.99 w/ free shipping

Intel Pentium E2160 Allendale 1.8GHz 1MB L2 Cache LGA 775 65W Dual-Core Processor - Retail $71.99 w/ free shipping

Total: $140.98

The cheapest Pentium D 940 I saw was a little over $100. So, spend another $40 and get a real upgrade. (Or even better, add another $12 to step up to the Gigabyte GA-P35-DS3L motherboard for $79.99. This will bring your total to $151.98 and allow you to OC your processor to 2.8-3.0ghz with ease. This will EASILY smoke the Pentium D 940 solution you are looking at.)

You can even chop off a few more dollars by going with a E1200 and oc it the 512Kb of L2 doesnt make a huge difference compared to 1mb.

Problem is I've never swapped out a MOBO. Seems allot easier to just swap out a chip turn the power back on and run with it. Or am I just being a newbie whimp ??? Point me in the right "Directions" and I'll give it a shot. Is my present memory compatible. 2 Gb PC2-3200
Thanks.
$150.00-$200.00 bones is no prob.

I'd skip the Pentium D and get something based off of the C2D architecture. It should be faster stock and will have plenty of overclocking headroom. Also, less power/heat, and you can use the same motherboard for a quad down the road if you want.

On a $200 budget, I recommend this:

Intel Pentium E2160 Allendale 1.8GHz $71.99 w/ free shipping

Gigabyte GA-P35-DS3L Motherboard $89.99 (shipping $5.84)

G.Skill 2GB (2 x 1GB) DDR2 800 (PC2 6400) Dual Channel Kit $44.99 w/ free shipping

Total: $212.81 shipped

Agreed. This is what you should get as it will be cheaper and boost performance by a lot:

Intel Core 2 Duo E4500 $124.99

http://www.newegg.com/Product/Product.aspx?Item=N82E16819115031

Also your mobo can support memory up to PC25300/DDR2667. If you want to boost it and put in 4GB then this is pretty a good deal:

Patriot 2GB PC25300 $40.99

http://www.newegg.com/Product/Product.aspx?Item=N82E16820220296

But you only really need the CPU. The RAM will boost performance for you a bit as well since it will be better quality.

These guys are correct, this is your best upgrade performance per dollar.

Just from my experience. I went from a P4 630 to D940's on a couple of PC's, and it did make a pretty nice performance increase. Yes it is true it does not perform as well as most C2D's, but it is a noticible improvement over the 630.

Sorry about that then.

Leave it to HP to use the same part # on two versions of a board. I'm glad you're well researched enough to know which version of this board you have.

I just did a quick internet search, and have found report from other HP owners that using a 9xx series pentium D will work just fine in your motherboard, so you don't have to use the old 8xx series.

Thanks for the time and help everyone. Much appreciated. I'll go with the D940 till I feel comfortable enough to swap out the board.
 
Off topic.
My wife saw your avatar and said I must reply. We have had pit bulls for over 20 years. People think they are bad animals , but they are not. They just have bad owners.
They are one of the smartest ,most loyal, protective and loving breeds. But the problem is they will do whatever their owner teaches or tells them to do.

One more ?
HP mobo specs say up to 3.2GHz(D940). SiSandra claims The board will handle up to 3.8GHz(D9603.6GHz). Could I go with the D960????
Thanks again.

I wouldn't spend that much money on it. The increase from 3.2 to 3.6 isn't nearly as much as it sounds. Buy a reasonably priced processor and safe some money for your next upgrade/pc. If you really need that much speed you still can overclock. The Pentium D 9xx series seems to be a decent overclocker. I would look for a Pentium D 9x5. Those are usually priced below the 9x0 and offer the same performance.
If you really have to, i'm convinced a 945 or 950, 960 would run on your board too. Those are awfully expensive for their performance though.

I have the exact same board. Last Dec i went thru the same upgrade and questions. I talked to HP support for weeks. The limestone will support up to a Pentium D 920. That is what i put in it. It works great. I got 20-30 FPS more on COD4. It runs very cool on my stock P4 fan that my HP came with. I would not recommend a PD 8xx. They are way to hot. HP support told me that the PD 920 was the highest PD 9xx that our board will handle.

I just reviewed my saved emails from HP support and that is correct.

I would recommend going to HP support and getting the latest bios. You will need it to support PD9xx cpus.

perfomance per dollar, i determined in my research the 920 was the best bang for the buck. I got it on ebay for $70. It might be cheaper now.

My machine is a HP. I added a antec 500w basiq, 4G of 800mhz DDR2(running at 667), Nvidia 7600GT and the PD920. It runs COD4 at 50-70 FPS, TF2 70-90 FPS, BF2 & bf2142 40-70 FPS on a 24" wide monitor at 1124x864, 2xAA, 2xAF. That is not bad for an old machine.
