Dell RDRAM Question

By replytohere2004 ·
Hi,
I have a Dell Precision 340 Small Desktop with 256mb of RAM.

It has 4 slots for the RAM, all of which are filled. The first 2 are filled with 2 sticks of 128mb RAM, which duly brings the total to 256mb.

My question is this, what are the other 2 slots filled with? Is this something to do with RDRAM?

The following markings are on the RAM:

Samgsung, Korea 0218h 128mb/4,
MR16R1624AFO-CM8,800-40 011 ,
is written of the first 2 sticks, which are larger then the second two, and which have a kind of steel casing around.

And on the other 2 sticks:
Dell GX B-VOA
94V-0
PWB 958780 REV A02
0212-01

Many thanks in advance
JimBob

Also, while I'm here sometimes when I press buttons on the internet for sending info, like the "submit my comments" just below me nothing happens, I usually have to click a number of times. Now, I'm a young man and I'm well able to click a mouse a few times but I'd don't want to send multiple posts ect.

thanks!

it fake

by steven_baumbarger In reply to Dell RDRAM Question

basically rdram has to have all four slots filled with something two are actually your ram the other two are just there to make a complete circuit that is needed to transverse the signal
so in essance fake ram

Possible answer.

When dealing with this type of RAM or another type of RAM, check out the type of motherboard on the internet by checking out the markings on the board. Usually it is in large white lettering or another color.

Some types of RAM have to have empty slots filled with a dud type RAM (like filling up space in a computer bay without actually hooking it up) to allow the computer to utilize the other RAM.

The steel casing around the RAM is the heat sink. Newer RAM generate alot of heat and this is the way to keep it cool.

So my advice is to check to see the type of motherboard you have, print out the manual (if you don't have one) off the internet.

Do some tweaking by using the motherboard manual to see if you can up the bus speed. Thereby taking advantage of the speed of the newer RAM with the heat sink attached to it.

You may have to go into the system bios (it's different to get into each one, so you'll have to check the startup screen or the motherboard manual) and enable the different features of the RAM (if it doesn't automatically recognize the changes).

After that, you should have no problem with the RAM.

CRIMM

by VirtualGardener In reply to Dell RDRAM Question

The "fake RAM" as the previous poster so eloquently called it is refered to as a CRIMM module or RIMM Continuity module. RIMM is the name for the RDRAM (metal casing) memory chips you are decribing. It allows current to flow through the entire bus circuit, which must have continuity from end to end. This is the reason the slots must all be filled at all times. Your computer will not work without them. You should have slots numbered 1-4. It may be very small, but there should be some labels on the motherboard itself. If not, slot number 1 is usually the one closest to the processor. You can have one of the RIMM memory modules in slot 1, and one of the CRIMMs in slot 2. Always put the RIMM in the first slot of a pair. Repeat the process for slots 3 and 4. Or you can have both RIMMs in slots 1 & 2, and both CRIMMs in slots 3 & 4. Makes no difference either way, but if you wish to add more memory later on, keep the chips in pairs. Leave the 2 original ones together in slots 1 & 2 and add the new pair to slots 3 & 4. Don't mix them together.
As to your Internet Explorer problems. Try downloading and running SpyBot. You should find it no problem with a quick Google search. You may be suprised to find out what programs are running on your PC without your knowledge. I always start there when diagnosing IE problems.

The two other slots contain dummy RAM, which does nothing but fill the slots. All RAM slots have to be filled on an RDRAM system. You can replace the dummies with extra RDRAM if the need arises - but you will have to replace both dummies, not just one, and the new pair of RDRAM modules will need to be of the same capacity. Also, they will have to be the same speed as your existing ones, i.e. PC800. My computer came with two modules of 64MB + two dummies. I replaced the dummies with an extra two modules of 128MB each, bringing the total to 640MB.
