Integrated Ram on a Motherboard?

[magomago]

I was thinking- as we are appraoching DDR2 and whatnot, I remember a topic a while back asking why the ram on Videocards are much faster. One of the ansewrs was that is was soldered and close to the CPU/GPU/VPU of the board so it could reach higher speeds. What about motherboards with ram soldered right on them (512megs-1.5/2gigs). Yeah any upgrade path would be prettymuch nonexistant, but it would definitely allow for faster speeds....

Just an idea I suppose

They already do that with some notebooks "building in" 128,256, or 512 of ram and leaving one slot or two open for more ram.

It would be a niche market for desktops but maybe a nice alternative for some buyers.

I think that has more to do with video cards using 128-bit to 256-bit wide buses vs the 64 bit ones on most CPUs today.

My old Packard Bell 486SX 25Mhz had 4MB of memory "onboard".

I was just coming in to mention my Compaq Presario 133mhz came with 8mb on board.

I remember when an extra 4MB SIMM cost me almost $300 bucks! And that was on sale! It was so worth it though. Sim City 2000 ran great after that!

ECS sold some MB's with 256MB RAM soldered onboard along with the onboard CPU.

HA! A collegue from my University has such a board. The processor is soldered into the socket and the heatsink soldered to the processor, then screwed down! Then they gave this 1100Mhz Duron a PR rating of 1400+
LOL.

Anyway, what was the question?

Oh yeah. No, this would not work.

Umm...yes.
The heatsink doens't have a beveled edge and is actually glued to the substrate and the socket.

Soldered!=glued

WTF are you two talking about? Solder and adhesive are two different things. And as for a bevelled edged, dude there is no ZIF socket, why would the HS need to be stepped?

Okay, well then technically the processor isn't soldered to the socket either. I'm just rolling with that since that's the word the first person mentioning these boards used. The method of permanently attaching the components isn't particularly relevant here except to the very anal. The point is that they're permanently attached.

Obviously it doesn't. I mentioned it because this is how it makes contact with (and is glued) to the socket.
And YOU sir were the first to use the word "solder" when referring to the ram. It most certainly is not soldered in either.

How do you think the RAM or CPU are attached to the MB?

The DIMM has three dots of glue on each side attaching it permanently to its slot.
Likewise, for the processor, there is a ZIFF arm but the processor is glued to the socket, and the unbevelled heatsink glued to both the processor and the socket. Thermal adhesive for the die and actual glue for the socket.
Of course, this is completely irrelevant to the point of this thread.
Back on topic, shall we?

LMAO! Dude look at the back of any MB.

In the case of the MB I was referring to, the 256MB of RAM that comes with it is soldered onboard, however it does come with Dual Inline Memory Module slot (which again is soldered to the MB) for adding more RAM.

Good. So we are talking about completely different boards. Mine is a K7SoM. If you would like to discuss this further without destroying this thread, you know how to PM me.

I was thinking more along the lines of NO expansion slots for ram.... but instead you get 1 gig of videocard-grade ram vs ddr400

b/c by allowing extra slots and whatnot, that would reduce the speed of the ram...So I'm not talking just soldering pc3200 1 gig...I'm talking about soldering some serious fast stuff with no upgrade path...but its seiorus fast stuff

GDDR accomplishes this by sacrificing latency. This works fine for a framebuffer. This does not work well for main system ram.
