will i kill my pc if i stick a C2D in P4 board

My board:

asus P5LP-LE (Limestone 1.04)
northbridge intel 945g
southbridge 82801GB 1CH7
socket 775

will i kill my pc if i stick a C2D in P4 board. My current CPU is a P4 3.0G HT 630 800Mhz. Will a C2D give me any real boost?

The c2d will give a big boost but it won't fit that I think. It's likely just to recognise the cpu as an unbranded one so it won't work properly but don't think it will destroy your machine but I'm still on socket 939 amd so it's conjecture on my part.

The Core2 would fit but it will not work. However you could get a Pentium D. Since that is supported by the motherboard. But Pentium D's are just a hot mess lol.

That is an HP board direct from Asus so hard to find data. It does have a 945G and the link I posted is the latest bios from HP and Asus. It says it supports newer Intel procs so update it and find out. It isn't going to damage the CPU just will or won't recognize it. Good Luck!

If you get the processor and it doesn't work a new MB that will work is fairly cheap and will be a much faster system.

Agreed. Pentium D's = BAD!

Thanks guys. By the way, the bios link above is for vista. I have xp.

The pentium D is cheap. The reviews on Tigerdirect are good. So the PD is a dual core? I stayed away from the D because of bad review a couple of years ago. Would a 3.0 Pentium D be worth $60 and would it give me any boost in performance? How about OCing it? Can i use my current stock fan?

EDIT: oops, the above post, posted as i was writing this.

What if i get a good cooler? Would it give any benefit? or should i just OC my P4 3.0 and wait for my new build this spring for a C2D?

Latest XP Bios...sorry

Pentium D's aren't much better than Pentium 4's unless you are photo editing/video encoding/multitasking and even then it's not close to a C2D. For gaming a Pentium D is the same as a Pentium 4.

I think it's worth and updating your BIOS and check sometime it may work,sometimes it won't recognize your C2D

Reply to lolitha

a BIOS update and Pentium Dual-core E21x0 series would be much better than a Pentium D.

HP is telling me that the Pentium dual cores wont work with this board. Even tho New egg has boards almost identical to mine that support Pentium dual cores and C2Ds.

Edit: hp support is also saying that this board will take the Pentium D 8xx but not the 9xx. The difference is 90 - 65nm and 1M - 2M L2 cache.

I dont understand.

Not if you're running one of the many games that are optimized for dual-core.

The smalled the "nm" chips take less power and generate less heat. The larger L2 cache = better in most cases. As for the 8xx and the 9xx I'm guessing those are revisions of the Pentium D... which I still recommend you do not get. I doubt you will notice much difference between a P4 and a Pentium D.

It's still using netburst architecture though, and generally performs very poorly when compared a real dual-core chip.

Pentium D's have been replaced by core2duos with the cache cut to 1mb. Old pentium D's might still exist but the e21xx series are core2duos.

What you said before was that gaming would be the same with a P4 vs. PD. Now you are saying that the PD is not as good as the C2D or X2. The second statement is obviously correct but the first is still wrong.

That was MadMike that said that Pentium D is the same as P4, read again please. *edit* You even quoted him in the post above mine.

I said I doubt you will notice much difference between P4 and PD. Which is true - the Pentium D is still using P4 architecture. When C2D and X2 came along - they blew that crap out of the water and unleashed the true potential of dual-core chips.

There will be a huge difference with the new pentium D e2140, 2160, 2180.

Yeah, because the e21xx uses Intel's Core architecture, but the old 8xx and 9xx still use Netburst.

The olds ones are discontinued so why bother. For the same price as an old one you can get the 2160 and be way better off.

Well, if you read above, you'll see that his board only supports 8xx. So I said it's entirely not worth it if that's all he can get.

Because, hp says my board will only support prescot and smithfield. apparently the new 65nm chips is the cut off for my board. Do you think my board will take a Pentium D e2xxx?

That brings up a question. Will the Petium D e2xxx chips be a noticable improvement over my P4? My p4 is 3.0 with 2M L2. The PDe2XXX chips are a shared 1M L2 and low speeds. Does the low chip speed an apple to apples comparison? 2 cores of 1.8Ghz versus my 3.0 HT. Will the lower L2 hurt my gaming. I have noticed on tom's charts that higher L2 and FBS is a big bonus for FPS. Since i will obviously be staying at 800Mhz FSB then will the L2 slow me down?

Edit: I was writing this post when the post above was posted. I will be installing the forementioned new bios tonight.

The cache doest hurt much. I have the e2180 over clocked to 3.3 and I play Crysis and Call of Duty four with it.

Reply to roadrunner197069

yep, i just realized i was wrong about the L2 cach.

Hmm. I am now in search of compatibility info between the E2xxx PD and my board.

What utility are you using to OC it?

The bios but the Asus atility works as well. Asus P5K SE board. @ gigs Adata Ram pc 6400 $49.00

i cant find an Asus OC utility.

Reply to 50bmg

Manufacturers don't tend to do "Overclocking Utlilitys", you just up the FSB in the bios, and the core voltage if required.

Reply to quantumsheep

IF YOU can not verify C2D compatibility

Not sure of your buget, But I think I (Agree with others that C2D is the way to go) you can find a E2140 for approx $75 and a replacement MB That would alow future upgrade to quad core proc for about $80 -> $100.

From there it would depend on parts that you could carry over.
Primarily memory - Is yours DDR2, and GPU (Agp vs PCI, PCI e)

Keep in mind, the money spent on a P4/D8xx now would be waisted if you end up dissatified and 6 monthes from now end up "Buying new upgrade".

Im pretty sure your mobo isnt compatible with the e21xx series as they are conroe cores, "actually the been named to allendale because of the shrunken l2 cache." And if you have an Asus board that didnt come with OC utility on the CD then your Bios most likly wont let you over clock either.

I thought I had heard something about the HP boards that ASUS made not supporting 65nm (Core2) but the ASUS branded board of same type supporting them. Stupid HP... (this is just conjecture, I think I remember it, but not sure)

Regardless of the architecture, there is still a relative increase in speed when going from one core to two cores on a multithreaded app.

My experience with HP. The last time I owned an HP was probably 4 years ago, so they may have changed... For a novice user, they are pretty nice, but if you want to upgrade anything besides RAM... get a Dell or build your self. HP often uses proprietary parts so that you can't simply go out and change a standard ATX power supply into the case w/o some serious case modding. Get the dremmel out! The motherboard I had in my last HP was also shaped slightly different than a standard ATX (stand-offs slightly off as well) It wouldn't surprise me if they loaded modded BIOS into a mobo that only supported a few chips.

There is a difference from one to two cores in multi-threaded apps., I don't deny that, but the PD 8xx and 9xx have a number of problems besides that architecture that also contribute to the speed problems that they posses. I didn't say there would be no difference, but that you wouldn't notice much of a difference. I'm just trying to point out reasons to justify not purchasing a PD 8xx or 9xx when he could just save his self an extra $100 and use it later to buy a better system.

I hear ya.

How about this- if he wants to do a major upgrade of his system in less than a year, don't bother with the PD.

If he wants to get one or two more years out of his current system and he regularly uses multithreaded apps, spending the $65 or so (PD 820 ebay plus new thermal grease) might just be worth it.

Thanks rgeist554, I was out of the office and you pretty much answered how I would have. I do not consider the e2xxx a Pentium D. The e2xxx are Pentium "Dual Core". I know that some of the non HP Asus boards will take the Allendale's but I am not sure the HP version will. He can try it and just buy a different mobo if it doesn't work. Either way it is better than a Pentium 8xx or 9xx.

be very carefully about ram speed and cpu you choose,
the E2XXX and E4XXX fsb is 200
the E6XXX fsb is 266.
if the memory is ddr2 400, E2XXX and E4XXX are good. E6XXX will not boot.
and do not foerget update to the newest bias!

You can use what ever ram your mobo supports. Who would want to use ddr2 400 with these new cpus? The motherboards for these CPUS probably dont even support ddr2 400. Best bet would be DDR2 667 or 800.

Reply to roadrunner197069

The mobo auto detects RAM clock and downclock it accordingly to accepted rate. But some old mobo LGA775 does not support E6XXX processors though FSB support tells. So dont go to much to the latest just near on your processor.

If i could find a PD 820, cheap, i would try it. I read a few articles including some from Tom's about the Pentium D's. I also look up a lot of benchmarks and i used Tom's CPU chart to see what i might expect. From all the charts and benchmarks i should see some benefit.

I am aware of the heat. I will get a good cooler and stay away from any overclocking. If i can keep it cool, i will probably not need a new "BOX" for a while. I just ordered a ATI HD 3870 and I just bought a Samsung 22" widescreen monitor, 1000:1 & 5ms. I upgraded my power supply a few months ago.

any ideas where i can find one, a Pentium D 820? They are not readily available. Anyone got one(that works) that they would donate? LOL. Really, any realtors or sellers?
