Motherboards for Athlon. Which has most memory slots?

**Kzin** · Apr 29th, 2003, 06:13 AM

Which motherboards for Athlon (2100) has most DDR memory slots? If I can find one with 4 or more DDR slots this seems a cheaper than buying 1GB DDRs

What a wacky way to expand your memory

The only MB's you are going to find are dual XP/MP's, which are practically server mobo's.

Try Gigabyte's 7DPXDW(-c or -p)

They are dual processor and i'm pretty sure have 4 DDR slots.

Many have 4... two are black and two are grey. I believe the ones closer to the CPU are the full-speed ones (depending on your chipset, 333mhz or 400 mhz or 466mhz... etc) and the two farthest are the lower-speed (say 266mhz).

There are actually very few domestic platform mobo's with 4 DDR's, as it's usually not required. Search google for an entry of a domestic mobo 4xDDR or "4 x DDR DIM slots", and you won't find any without Grand champion chipset... ie server boards.

Mobo's with the "two black & two grey" feature, usually specify that you only use one or the other, not both.

Everyone recommends you run the same speed memory throughout your system, so having one at PC2700 and the other's at PC2100.. is pointless and probably unstable.

Their are some new P4 Mobo's which have 6 DDR PC3500 compatible slots, but again... pointless if you want to use two different speeds of memory.

Regards,

Paul.

,....who the hell would need 6 DIMM slots????

3 is plenty (KT400), but for nForce2 I'd prefer a 2+2 arrangement instead of 2+1.

**siyan** · Apr 29th, 2003, 04:41 PM

erm...well i see how servers would need 6 DIMM slots....presumed that it was desktop mobos you were takling about

**Edneeis** · Apr 30th, 2003, 12:12 AM

If the chipset can handle 4 then most Abit boards have 4 slots, most except the nForce2 boards. Although you can get ram pretty cheap at newegg.com and probably be better off instead of buying a new board.

Yes I have one of those right here! But of course you canm only use two slots at a time.

Beacuse with 6 DIMM slots I could have 3GB of memory for about 150GBP ($250) whereas with 3 DIMM slots it would cost more like 450GBP ($750) and with 2 DIMM slots I don't think it can be done at all.

but unless its a server or very high end workstation, you don't need any more than 512 really.

"640 KB should be enough for anyone"

I've got 1GB at present and its really restrictive. I really need about 8GB at present.

I agree.

Although I am running 1Gb at the mo... only PC2700 though!

I've given up on PC3200's, they don't last me long enough!

Wisdom was in short supply then, but I think you'll find many who agree with me now. (Thanks VisionIT

) Right now its really only the gaming industry and several more obsure industries that are really driving PC hardware development. For the rest of us, what we have right now is overkill.

(Just imagine the graph of f(x)=ln(x)

I own a P4-m 1.6, 256MB, 30GB, and aside from only having about 11GB free (

) I'm doing just fine.

If you need more than 1GB then I assume you're running a large database server/large web server, or doing a lot of 3D rendering and such. That would qualify as a high-end workstation/server.

Or you just have too much money.

My shuttle ak35gt2 has 4 dimms but why would you ever need more than a gig of ram? If you are actually using 1gb of ram you must be doing something wrong on your computer.

Plus Ça Change, Plus C'est La Même Chose

Case I (real). Consider carrying out Fourier & Laplace transforms on datasets which were in excess of 16GB. Even with careful data reduction and matrix manipulation these can be reduced to ~1GB but even the processing needed to do this manipulation is heavy. Consider how long it thakes to do a write 1GB to RAM vs how long it takes to write 1GB to a swap file. How about 1000 read/writes? How many for an FFT

?

Case II (another real one for me). With VMWare I can run as many virtual machines as I want on my PC and get a fast and dynamically re-configurable network for testing and analysis of multi-client server systems. If you want to model and test a network with guest machines with 256 MB ram (so they can have a realistic App load) then you can only fit 3 in 1 GB or you have to reduce each Virtual machine to about 64MB but they you spend all your time watching them running out of memory. Paging for host or guest is a bad idea with VMs.

I agree 1 GB if fine if you are just writing your CV in word or 'The Sims'. Not everyone runs the same tasks on their PC

I used to make a 10GB Origin 2000 swap like a beast ^_^

**siyan** · May 5th, 2003, 12:27 PM

in such a case you should have a server farm.

besides which, i do believe i said something about the excluded case of servers and workstations in my original message....

**siyan** · May 5th, 2003, 12:28 PM

by server farm i mean a bunch of computers sitting there running a MATLAB kernel and assisting over the network (I assume it can do this)

If you remember the limiting factor was the amount of local memory not the processor speed - so one CPU accessing 2GB of local memory is going to be a lot faster than two processors communicating over ethernet accessing 1GB each.
