Socket 423 478 converter (PL-P4/N)

October 31, 2008 at 09:01:28
Specs: Windows XP, P4 1.3/256MB
Hello. I'm thinking of upgrading a midtower that was given to me:

- Motherboard Intel D850GB
- Pentium 4 1.3hz FSB 400 Socket 423
- 2x128 PC400 RDRam Kingston (gonna add 2x128 samsung)
- 40GB HDD

I have access to a Powerleap PL-P4/N converter, that can fit a Socket 478 Pentium 4 on a Socket 423 board.

What i can't find, is a list of supported CPUs/speeds that can be used with this converter. His original homepage doesn't work, because this product was discontinued. All i know is that it accepts Willamette and Northwood.

I know 400Mhz FSB Northwood goes up to 2.8Ghz, but what i don't know is if i can use a 533Mhz FSB P4 with this converter. I know speed will be slower (ex 3.0Ghz 533Mhz = 2.25Ghz 400Mhz), but it's difficult to find a 400Mhz FSB for a reasonable price.

I only do what the voices in my head command...

i would be suspicious of a CPU socket converter. if you were pinching every penny you could give it a try, but you're planning on buying more components anyway. You could spend a little bit of money on new components for a low to mid-range computer, that would still outperform the machine you are trying to upgrade, and leave you more room for future upgrades.

RDRAM is overpriced, Skt478 P4 are out-of-date! In the UK I sell Celeron 2400mhz Towers for under £50.00 with 512MB Mem and 40GB HDD, why pay out that to revive an obsolete PC?

I'm going to use this tower in an arcade project running Mame, so i don't need a powerful computer or future upgrades. All i'm going to use is a special 15khz AGP card (that i alredy have) and an average cpu, that is why i was thinking on upgrading with a 423/478 converter and an older P4 cpu.

I was just asking for help to see if someone could find a webpage with a compatible cpu list for the powerleap PL-P4/N.

EDIT: Celeron 2400 vs P4 2600? I go for the second ;)

Did you even try a google search on this adapter
http://www.geek.com/articles/chips/...

The 4th and 5th response both say the same thing

Yes i did search, otherwise i wouldn't have found this:

http://duhvoodooman.com/powrleap/P4...

where his performance boosted 2x from a P4 1.3ghz (the same i have) to a P4 2.6ghz.
By the way, upgrading from a 486 to a Pentium isn't the same from a P4 s423 to a P4 s478, both P4 are basically the same, only the pins are different.

By the way, read the last comment in your link, that user has the same board as i, but he says that CPUs with 533 or 800 FSB are not compatible, although i have read on other pages that it is.

I do not remember posting about a 486 upgrade.
You will get no where near 2x the performance from this upgrade, benchmarks are not real world performance. But good luck with your venture.

Sorry for the late reply, i didn't have Internet this weekend...

I know you didn't talk about the 486 upgrade, but you mentioned the 4th and 5th comment from your link:

"The reason I'm in the IT field right now is that I researched one of those 486 to Pentium adapters and found they weren't worth a s---, and started building PCs as a result. A performance hit of 5-10% wouldn't surprise me in the slightest. - by Just buy a new mobo!"

And i mentioned the last comment:

"I'm always skeptical of hardware upgrades based on old tech, but this one works fine. Moved from a 1.8Ghz to a 2.8Ghz system, on a D850GB motherboard with 1GB RDRAM... Only been a few days now, but it seems okay. For general use, speed cannot be noticed all that much. But video encodes at least 25-35% faster now. Audio encodes are much faster too, almost twice the speed as before. Well worth it... The Intel D850GB is a very solid system... Max CPU speed is 2.8Ghz at 400FSB... Must be 400FSB, not 533 or 800 or whatever else."

I just asked for help searching for some kind of compatible CPU list, because i read elsewhere it supports 533 FSB. If it does, i might find a cheaper used cpu and avoid a bigger upgrade.

I don't need a top end machine, just a better CPU, because MAME relies on CPU power and not on graphics card power. Heck, if i used a S3 Trio, MAME would run at the same speed ;) but i have to use a special 15khz AGP card because it connects directly to a 17 inch arcade screen.

From what I have read there are issues with compatibility on CPU for that adapter. That is why you may be having problems finding a list of CPU. I have an old Dell 8100 I purchased new, w/ P4 423 & RAMBUS, it was cutting edge back in 2001, and I just acquired 2 more. I had looked into that upgrade but decided it was too costly. But now that I have gotten 2 more in a trade, I would consider trying it. If you decide the upgrade is not for you (RDRAM is way overpriced) I will buy the adapter. I would like to experiment as a learning experience for my 13yr old son.
Reply if you are interested.
Thanks,
MM

I think you are out of luck. A friend of mine gave me a bag (those black ones we put trash in) full of computer stuff. Among other things, there was a burned motherboard with a working Pentium 4 2Ghz FSB 400 Socket 423 and 2x128 PC400 RDRam Kingston. Since the Powerleap PL-P4/N converter can only upgrade up to a 400Mhz FSB Northwood at 2.8Ghz, i'm not investing in an upgrade anymore.

The Powerleap PL-P4/N converter i mentioned in the 1st post was in an auction page (similar to ebay) and now is long gone.
