Some information on a P4 2.8ghz

[skeeterific53]

Hey Everyone!

I am kind of a n00b on here. I lurk a lot but don't really post much.

I just inhertited a Dell Diminsion 8200 from a friend for FREE! It had 256MB memory and a P4 2.0GHZ in it. I upgraded to 512MB first, and then 1GB RAMBUS:roll: and then I got a new cpu on Ebay which was a P4 2.8, the largest cpu to be able to fit with this MB.

It seems as if my PC boots slower since I switched the cpu. I thought I would have seen a big difference. BIOS detects it as a 1.4ghz, and I believe it does this because it is a a P4 Hyper Threading. XP recognizes it as a 2.8 I remember back from my school days that this was the beginning of the dual core days when these CPU's came out., so I think thats why BIOS detects it like that.

I was wondering if I can overclock this, and what do I need to do to perform this? Is there some software to download or something? Again, n00b here, sorry. Also, what is the max I can put this CPU up to without hurting it?


Below is the information I got from Everest......

Hmm, it seems that the motherboard reverts it back to a 400MHz FSB. Maybe that is the limit of your motherboard? I remember that some S478 boards couldnt handle the 800MHz FSB of the newer processors.

Skeeter, your problem is that you bought the wrong processor. Your motherboard's FSB can't go any higher than 100 Mhz. Your new CPU's FSB is supposed to run @ 200 Mhz, so it's only running @ half speed, and on that motherboard, that's the fastest it will ever run. There's nothing wrong with either the processor or the motherboard, you just can't use them together.

You bought a 2.8C, and you should have bought the more expensive (now) 2.8A. Here's a link to one, if you're interested: http://www.starmicro.net/detail.aspx?ID=542 BTW, if I were you, I'd grab this 2.6A: http://www.starmicro.net/detail.aspx?ID=115 Good luck.

edit: Hmm, they have a 2.8 Ghz Celeron, which has a 100 Mhz FSB, for cheap! Here's the link: http://www.starmicro.net/detail.aspx?ID=540 <<--That's definitely what I'd buy.

I think Andrew1990 is right. I don't know for sure if you can go into bios and set the FSB to 200Mhz or not? Also, I dont know for sure if you can update the bios. Seems to me that you probably won't as they're locked. You most likely have this CPU and you should have this one. Take not that it's NOT hyperthread. Check if that Motherboard can support hyperthread. Its a Dell so you are very limited at what you can do with those boards.

Edit: Myo posts supersedes!:thumbsup:

Actually, this looks like a Pentium 4M(Mobile processor). I have a similar (3.2MHz) processor in an Asus desktop motherboard. Because your MB BIOS does not correctly recognize the mobile processor's Speedstep cpu throttling function it defaults to the mobile processor's idling speed. The only way I got around this on my MB was to select a lower memory speed (in BIOS) and overclock the FSB. I don't think that would work with your Rambus based system.

That could be true, but isn't, because the multi for the mobile processors running in a desktop mobo happens to be 12x, not 14x as noted in the OP.

 

[THUGSROOK]

mobile would default to 12x multiplier, its not a mobile.

the motherboard is older then the cpu, it doesnt reccognize it.
manually set it for 133fsb is the best youre gonna get, it might OC to 150fsb but thats about the best the board can do. the rdram has ratios and is a bit tricky to OC.

HTH

IMO: dump the RDRAM board, get a dual ddr400 board.

 

[Phynaz]

This is a Dell.

He can't set the FSB or RAM ratios, or replace the board.

 

[skeeterific53]

Well I updated the BIOS to the most current, A09, and still the same. Ohh well, I will just run with it until I can get a new PC. This one was given to me, so I am not complaining too much. Its not the primary PC anyways.

there are ways around everything

this is the OCing forum after all.

Dell did use Asus boards, if his is an Asus board he might be able to flash the real Asus bios onto it.

but again its RDram, replace the platform.
everything is proprietary dell? trash it, or run Win98 on it for DOS games.

"Hmm, it seems that the motherboard reverts it back to a 400MHz FSB. Maybe that is the limit of your motherboard? I remember that some S478 boards couldnt handle the 800MHz FSB of the newer processors."

-CPU's w/533MHz FSB's may also have a problem with this. So don't bother trying it with a 533MHz FSB chip.

-The chip cannot adjust to 400 because it's locked at 800 to get to 2800MHz, and only the motherboard features can tune something like this. Obviously not the case with most standard equipped Dell's.

"IMO: dump the RDRAM board, get a dual ddr400 board."

-Don't forget about the processor compatibility features you want. Aim for an FSB800 motherboard if you should go this route. But being as is, it'd be better to gear for an Athlon X2 3600 system, perhaps. Upgrading again on the Intel 478 path might be a waste.

"This is a Dell.

-Don't forget that Dell makes gaming PC's. This is stereotypically a generalization. I think what you meant, was that the Dimension line isn't very fond of having advanced user adjustable, feature-rich motherboards, especially for Pentium 4 processor class systems.

-Speaking of which,
"edit: Hmm, they have a 2.8 Ghz Celeron, which has a 100 Mhz FSB, for cheap! Here's the link: http://www.starmicro.net/detail.aspx?ID=540 <<--That's definitely what I'd buy."
A 2.8GHz Celeron will be slower than the 2.0GHz Pentium 4, originally replaced by the newer Pentium 4.

You can notice the difference in just running 3D applications with a Pentium 4 clocked at a lower speeds and a Celeron clocked at higher speeds, regardless of whatever graphics engines are used, Intel, ATI, nVidia, Matrox, etc. The Celeron will almost always perform slower in overall system performance than the P4's due to less cache size and processor technology capabilities with the motherboard.

I recommend stop wasting your money on upgrading the system. I think after the 512mb in total system memory was added, you should of just left it that way. RD RAM is over rated and overpriced, that stuff is considered ancient now anyway.

 

[THUGSROOK]

afterthought.... try setFSB to get 133-150fsb. (windows OCing software)

 

[kotrtim]

The RAMBUS is running hot, PC-1200 version is running @ 600 MHZ, can't imagine what happens if you overclock it. The clock speed is even higher than the top DDR2. My opinion is to leave the system as it is, use until it dies. RAMBUS is obsolete, might be harder to get than SD RAM? I am unsure. Quantity of DDR is also decreasing these days and they are more expensive than DDR2

 

[Schfifty Five]

Do you still have the old CPU? Why wouldn't you just use the original 2.0ghz CPU for now? (unless you sold it or something)

So it would be a good idea to not sell the crap ton of DDR1 I already have eh?

OP

Install your old P4 chip in there and sell the new chip.

 

[skeeterific53]

So would running the old chip be faster than this one?

 

[Arcanedeath]

Yes the old 2.0 Ghz chip will be faster than your 2.8Ghz running at 1.4Ghz

 

[skeeterific53]

wow, alright then I guess back in with the old. I bought the 2.8 for 30 bux so it wasnt much of a loss.

 

[PeteRoy]

Get a decent old video card like a 6600GT or 6800GT if you can find it, it will help you more than a 2.8Ghz

 

[skeeterific53]

I have a Radeon HD 2600 Pro in it that I got on clearance from Best Buy for 55 bux.
