P4 478 to p4 755 solution?

ajbnew · 02-11-2006, 12:12 PM

Hi,

I looking to upgrade my present trusty Asus motheboard so I can accept a newer dual-core/emt64 bit processor.

Q: Moving from a P4C800 DLX (478 chip P3.2E)to an p5p800 SE, and using all of my other hard ware (Ati x-800xl, 1 gig OCZ DDR 400, 2 SATA Diamax9's, Xfi soundcard) will I notice a big performance boost with say a P3.4 L755 DCore

When I look at my present intel chipset--it is a i875 and now I move to a i865e. Is this not downgrading??? Any help, user experience or suggestions are appreciated. Thanx.

I'll start with the easist. Moving from 875 to 865 is not really a downgrade more of a sidewards move in chipsets.
Now for the hard one. Is dual core worth the upgrade? IMO no it is not. Although I do not know dual core, I know a little with my dual Xeon. I'll start of with when is my Xeons faster then my main computer. Extreme multitasking, ie two intances of folding, web browsing and hosting images over a network. Intel's dual core offerings will give imporvements in those areas, but as long as no more than one maybe 2 programs are memory intsensive. My main computer with the HT P4, will beat it at any single application alone.
Also the AMD64/EM64T, not worth the upgrade IMO. Unless you plan to take advantage of the 64bit processor with a 64bit OS, there really is no point into it.

If I was in your shoes I would wait and save some money for a PCI-E based machine where there will be a definate improvement in graphics, networking, audio, and all the new technologies.

Thanks for the input h20! I was kind of leaning into your way of thinking. Do you think a 3dr party adpater for the 478 socket will appear accepting the newer 775 chips from intel?

h20-ski · 02-12-2006, 11:20 PM

Due to the pins being placed on the mobo on S775, the likelyhood of an adapter is nill.

Edit reread your post: and no, there will not be an adapter for S775 processors to S478.

Look for a 945 chipset. Fully loaded for dual core, plus they won't break the bank.

I agree with Spookyload, but at the end of the day the 955X boards have dropped a lot in price, you could pick one up for a decent price now that 975X has surfaced.

Being a person that has a dual-core Smithfield system (no HT) and an older dual Xeon system with HT enabled on each proc. I'm finding my dual Xeon more enjoyable to use. Sometimes the Smithfield is faster due to improved throughput of the memory and a faster Raptor drive but the dual Xeon just seems the better of the two. The Xeon system I'm using is actually older than the 875 chipset.

I'm glad I found this thread as I have almost settled upon the P5P800 SE to replace my current P4P800S-X. The reason I have chosen the P5P800 SE is because it still supports AGP and also the same DDR memory that I have on the P4P800S-X while adding support for dual-core processors. That means the only other component I have to change is the processor making it an affordable upgrade (imo).

I can understand why you would recommend a 945 chipset, after all if you're upgrading why not make the biggest leap, but in terms of making the upgrade affordable a sideways move is an option to open up the world of dual-core.

Hope I've not caused offence to anyone. If I'm wrong and 945 does support AGP then I'd be interested to hear. I'm looking for just enough of a leap to enable Windows Vista at its best while not breaking the bank. P5P800 SE looks like a viable option.

A quick follow up, I read that Intel will be halving the cost of the 950 around April 2006 to allow for a new top end 960 (3.6ghz) processor. I seem to recall I read this on www.theregister.co.uk but I could be wrong.

Before you guys go out and buy S775 with AGP, make sure that the motherboards support the new dual core processors. Technically the 875P chipset supports SMP, but most motherboard manufactors have yet to build in dual core bios support.

h20-ski · 02-15-2006, 10:30 AM

What chipset are you running Pointreyes, 7505, 7501? Ya my dual Xeon is faster than my P4, but for everyday task they perform at near the same speed.

According to the ASUS support website the P5P800 SE supports processors right up to the 950. Would they make a board that doesn't fully utilise the processor that it supports?

h20-ski · 02-15-2006, 10:44 AM

Oh, okay a while back the 865/875 S775 motherboards did not support dual core. Asus built those motherboards when S775 first came out so that people could upgrade the processor while keeping the rest of their old system. They may have released a revision to support with beefed up the VRM.

The old E7505. Here's the now discontinued board that I'm using (even used the price of this board is higher than a new single proc board):

Hey Longview---
I'm now thinking along your lines.
MY short term solution is to pick up one of those P5P800 se because my investment in 2 gig of OCZ gold DDR-400, ATI X800xl AGP and X-Fi Fatality 1 can be used. All I would need is a new 950 Processor. Cheapest way to avoid obsolescence but sure miss the idea of getting DDR2 and PCIExpress.I've heard mixed reactions about how they improve performace is a drastic way over the P4c800 dlx. (which is no slouch by todays standards) But I hate thinking I can't upgrade processor beyond 3.4E!!!!
