Here's a tough one. P4 & V5 AGP

[Wizard25]

I am looking for a little more Horsepower for my computer right now. I got a P3 750 oc'd to 840 right now, with 768 meg of SDRAM. I would like to step up to a highly overclocable 1.6a P4. I am not looking for the gaming performance as much as I am looking to boost my C++ compile times, along with speeding up my Visual Age for Java workspace. (some of the things I am doing with school right now are getting SLOW on this machine.)

I would like to Keep my V5 5500, as it runs Counterstrike WAY faster than I need; and I also would like to try and get a SDRAM board, as I have 1 gig of SDRAM that I would use with this upgraded machne.

Is there any board that is : P4, SDRAM, and V5 compatible? other features can be as boring as ya want, I am on an abit BX6.2 right now, so I am not looking for anything exotic... well.. i would like to be able to o/c some.

thanks.

Well I don't know how fast thouse programs run on a P4 system, but I do know a P4 with SDRAM is incredibly slow (incomparison to DDR, RDRAM, and AMD systems). Ram is a bit more expensive than it was last summer, but going with an SDRAM P4 won't be as big of a jump as you might think, you'd be luck to cut your compile times in half.

If I remember right all of Intel's 850 and 845 boards only do 3.3v at the AGP slot. Since the V5 requres 5v, it won't work. You might look into boards with SIS 645 chipsets or the Via P4X266, although I'm not sure they support 5V AGP either.

 

[Wizard25]

hmm.. lack of suggestions is making me think the athlon camp is where I should be looking. hmm.. bummer. I like intel chips better. 😛

 

[Athlex]

Well if you like your V5 better, then AMD is the way to go. 🙂 Besides, and upgrade to an Athlon would probably give you a bigger performance boost in compile times than a P4.

 

[AA0]

the V5 will not work with a P4 board, you are out of luck. Move to an athlon, or get a new card.

News flash,
There are several makers with sdram p4 chipsets that can operate a 3.3volt agp slot!!!
The sis 645 and via p4x266 are the chipsets used. Gigabyte(8SDX), Msi(MS-6559) and ECS all build units that will run the P4. There are many more minors makers as well. I have yet to verify how well any of these with operate/overclock. So, I can't recommend any of them.
Keep in touch with me if you persue this upgrade faster than I do. I will bookmark this thread, and reply to it.
Let's see how far a V5500 can go🙂

ECS P4S5AT DDR/SDRAM both and it is very cheap.
SIS 645 so I gues V5 should be OK (not sure though).

 

[chasM]

the gigabyte and msi boards have three memory slots and the ecs board has two sdram slots.
wiz,
i hope you have some big memory sticks if you hope to get the whole 768 installed. You know there are a lot of voodoo users that are die hard intel too.

 

[Athlex]

Just to clarify- as with new PCI devices, newer AGP cards run at 3.3v while older ones (including the Voodoo3/4/5 and most pre-radeon ATI cards) run at 5v. The 645 and the P4X266 definitely support the newer 3.3v AGP standard, but whether they work at 5v is in question.

Athlex,
I'm not the know it all genius of AGP, but Ive been bustin' my butt trying to find a P4-Sdram solution. Just so you know the new AGP 4x spec. call out of a 1.5 volt slot. There is no 5 volt agp slot. Other than that , you seem to have the facts straight.

😱😱😱
D'oh, I was confusing PCI and AGP

 

[Torval]

I am probably wrong about this, but doesn't the Voodoo 5 get the extra power it needs from the
4 pin connector on the card?

 

[chasM]

Yes , but power isn't the issue. V5500 uses 3.3volt signaling to transfer data from the agp slot.. New Agp4x cards use 1.5 volt signaling. I'd guess they can due to their smaller Gpu size. (.18 micron dies). It would take a lot less time and work to condition a 1.5 volt signal to work faster as I'm sure the newer cards do .
