Is there an good socket 370 mother board for Pentium III tualatin processors with Rambus RAM and AGP 4x?

BAM:

http://www.acme.com/build_a_pc/boardfinder/se … gi?chipset=i840

Its missing a few boards, like the Aus p3c-d, and the intel i840 board, but that site is will always get you started.
take your pick.

I'd start here

Thats fine too, i suppose. I've done my homework and already determined if you want a rdram system, you have 2 choices. The i840 & pentium 3 or the i860 P4-xeon. THERE ARE NO OTHER CHOICES.

Care to elaborate a bit? What about the Intel i820 or i850? I'm actually curious - I've never personally owned an RDRAM machine. 😊

Don't forget the i820 - there are few boards based on this chipset. However I'm not sure if they support Tualatin.

I'm under the impression they were designed for Tualatin, what other late PIII could they be made for?

I would not waste time or money on an 820 system. Not when you can get an 840. the major difference is the memory. the 820 is single channel with a LOW maximum memory capability. The 840 has no such limitation (well the 32bit 4gb barrier)

RDRAM works better with Pentium 4 than with Pentium III.

There is no performance difference between i820 and i840 (I have both). The PIII FSB is way too slow even for single-channel RDRAM.
PIII @ 133MHz FSB has bandwith 1066 MB/s, single channel PC800 RDRAM has 1600 MB/s.

Sure, the RAM capacity is limited, but in my opinion 1GB is good enough for a Pentium III system.

As for the Tualatin issue - i820 was released in late 1999 and was originally meant for the PIIIB (133MHz FSB) - both Katmai and Coppermine. It was a replacement for i440BX.

well, keep in mind that I also deal with dual-cpu systems. While that's probably not the case here, the dual channel makes an INCREDIBLE difference in 2-cpu setups.

So if you are going to use windows NT, 2000 or XP for this build... ^.^ The games themselves might not use 2 cpus, but the 2nd one will be put to work doing network, sound, and other background tasks.

Have seen reports here on Vogons regarding a certain socket 478 board that are really unstable.
As for P3 with RD-Ram, I only have experience with my Intel VC-820 board.
This board is not Socket-370, it's a Slot-1 and it run's rock solid and stable with a P3-500.
I have 2 x samsung PC-800 memory modules installed in my system, with a TNT2-Ultra (Compaq).

I think that you should look out for reports regarding stabillity instead of setteling on a specific
socket, as I see too many claim's of eighter stable or unstable systems running RD-Ram.
It's like a black or white situation, regarding these systems.

Yet, they recalled 820-board's, running SD-Ram, as they were simply not cabable.
820 systems ran horrible unstable using SD-Ram. Well... Most of them anyway.
The 820-chipset was developed for RD-Ram.

I'd also like to point out that "Server class" hardware, like the i840, were designed to a higher standard than the average swill.

Case in point, capacitors. I've recapped MANY MANY boards, but only ONE server board. And it was only a precaution, it had one bulging cap and I replaced them all out of caution.

in fact, i'm trying REAL HARD to NOT buy this board: http://www.ebay.com/itm/301379717531

Found some interesting boards, thanks for replies guys 😀
Luckybob knows his server boards 🤣

I want to have an ultimate Pentim III, but i have decided TUV4X is enough.

A nice looking motherboard, however I see no mention of native Tualatin support in the manual, which means you'd need the Tualatin adapters or buy the pre-modded PIII-S chips. Adding up the costs of buying the modded CPUs, the RAM, the shipping, the motherboard, it would probably cost me around $350 CAD. I'm out.

How does the RAMBUS memory performance on this board compare to dual channel SDRAM, single channel SDRAM, and single channel DDR?

well... shit.

totally blew my mind there. they are coppermine boards! I was so distracted by the sexyness of the board it didn't even register that it might not be tualatin native. Further investigation has revealed it is NOT, so if you want tualatin chips, your going to need adapters.

moving along...

performance is kinda a grey area, it depends greatly on what you are actually using the board for. rdram has higher latency, but has more throughput. All are "close" but 2ch sdram tends to be the most responsive. let this website do all the talking: http://www.anandtech.com/show/715

For Win98se. My system with RD-Ram is stable. Performance wise, well.
I do not really see anything that makes me go for SD or RD.
They just plain works fast enough. Both technology.
Old tests like the ones on toms hardware and stuff, are all saying the same.
That back in 99/00, RD's were not worth the price you payed for RD systems.
I would say that you get 5%... 10% top. Increase in performance with RD-Ram.

Couple of Aida64 memory benchmarks on SDRAM and RDRAM platforms:

PIII 500 + i440BX (PC100 SDRAM).................................................................PIII 600EB + i820 (single PC800 RDRAM)

2x PIII Xeon 1GHz + i840 (dual PC800 RDRAM)................................................Athlon 600 + KX133 (PC133 SDRAM)

P4 1.5GHz + i850 (dual PC800 RDRAM)...........................................................Athlon 1400 + KT133A (PC133 SDRAM)

Maybe it would be good idea to compare Slot 1/Socket 370 chipsets in AIDA64, that are capable to handle 133 MHz FSB and Tualatin CPU's? 😀
