View Full Version : Mainboard Advice

I'm looking to get a mainboard for a P4 1.8GHz Socket 478 - 512Kb - Northwood that is based on the Intel 845. (I 'm using the 845 because I'm using SD RAM) One thing I would like is that the mainboard have 4 RAM slots

Thanks Khaine

Just one thing, you'd be cripplin' the CPU usin' SDRAM though and the end result will be very disappointing performance.
My suggestion would be to seriously look at a i845D board, 1.6A P4 CPU and 256MB of DDR SDRAM as the 1.6A will o/c just as well as a 1.8 and be cheaper, plus the price between a i845 and i845D board would be very little so the DDR SDRAM wouldn't be that much more to fork out over your original intentions and you would gain a great deal performance wise. :smokin:

What Wiggo said... my Pentium 4 runs about 10-15% faster in most applications with DDR instead of SDR SDRAM. Don't cripple a fast chip with SDR SDRAM - if you can afford a Pentium 4 you can afford DDR SDRAM :thumb:

Agreed. But if you opt toward DDR, you also have other chipsets from different companies to choose from. Read: VIA and SiS.

Well the thing is that I only just upgraded my RAM and I don't mind if it 10-15% slower than using DDR as It'll do me fine

For a high end system I wouldn’t touch a SIS chipset with a 10 foot pole.

And for reliabilty I wouldn't go past the Intel chipset,
VIA make good chipsets but they are still not a stable as an Intel or AMD chipset :p

Pretty much spot on there Moose.

At the moment (which is all we really know for sure isn't it?) that is absolutely correct.

It would appear that when it becomes mature the SiS 645DX might be a real performer. Have to wait and see on that one though.

SiS645DX looks awesome according to TomsHardware's recent review.

I'm currently running an Abit BD7-RAID board based on the i845D chipset and i'm very happy with it. Decent performance, very stable.

And what would you know, SiS are kindly sending us one for review - Keep your eyes open people! :)

So does anyone know of an Intel based 845 mainboard that has 4 RAM slots ???

03-15-2002, 12:05 PM
You won't find one as Intel only designed the chipset to support 3 DIMM's. :smokin:

Thats strange cos if you check out the table on http://www6.tomshardware.com/mainboard/01q4/011217/i845d-01.html this page you can see that it states that the max it has is 4

03-15-2002, 03:42 PM
Well I just went thru the major board makers sites before making that post and I only found 3 DIMM's as what was being offered. :smokin:

03-15-2002, 05:32 PM
ok, then looks like I'll be getting an Asus P4B266-E or a Gigabyte 8IRXP. I normally trust tomshardware with these things but it seems lately that they are getting really anti intel

03-15-2002, 08:15 PM
Something else to consider when looking at that linked page from Tom's site is that it covers what the chipset will support... not what the manufacturer will put on the board.

As an example, look at the VIA KT266A chipset. It supports a full six PCI slots but there are a lot of manufacturers who only put five on their boards.

Usually why the manufacturers won't support all the DIMM's is usually timing problems associated with the trace lengths to the furthest DIMM corrupting the performance of the setup.
They will usually drop it in favour of a stable and reliable setup. :smokin:
