View Full Version : I need more RAM info help!

Ok im not so good at the hardware side of computers so i need some help. I have a gateway with this kind of memory in 2 128MB chips.

General Description

The Rambus® RIMM™ module is a general purpose high-performance memory module suitable for use in a broad range of applications including computer memory, personal computers, workstations, and other applications where high bandwidth and low latency are required.
The Rambus RIMM module consists of 128Mb/144Mb Direct Rambus DRAM devices. These are extremely high-speed CMOS DRAMs organized as 8M words by 16 or 18 bits. The use of Rambus Signaling Level (RSL) technology permits 600 MHz, 711 MHz or 800 MHz transfer rates while using conventional system and board design technologies. RDRAM devices are capable of sustained data transfers at 1.25 ns per two bytes (10ns per 16 bytes).
The RDRAM architecture enables the highest sustained bandwidth for multiple, simultaneous, randomly addressed, memory transactions. The separate control and data buses with independent row and column control yield over 95% bus efficiency. The RDRAM's 32-bank architecture supports up to four simultaneous transactions per device.


High speed 800, 711 and 600MHz RDRAM storage
184 edge connector pads with 1mm pad spacing
Maximum module PCB size : 133.35mm x 31.75mm x 1.27mm(5.25" x 1.25" x 0.05")
Each RDRAM has 32 banks, for a total of 512, 384, 256, 192, or 128 banks on each
256/288MB, 192/216MB, 128/144MB, 96/108MB, or 64/72MB module respectively
Gold plated edge connector pad contacts
Serial Presence Detect(SPD) support
Operates from a 2.5 volt supply (±5%)
Powerdown self refresh modes
Separate Row and Column buses for higher efficiency
µ-BGA package type (62 Balls)

Ok, now i wanna go to either 512 or even up to 1g if i can afford it. what do yal suggest. Im looking for value as well as performance. If i can use my old memory i'd like to.

I need to find out what "style" of memory to buy. SD, DRAM, bla bla bla

Thanks !

sorry bud, you must buy more RDRAM. depending on how many slots you have for memory you might be able to keep some old ram. how many sticks of ram can your motherboard hold?

2003-04-17, 12:07 PM
4 slots

2 of which are occupied by the 128 sticks...

could i put 2 256 sticks in the other two slots or do they have to be 128s as well?

you can put 2 sticks of 256 in there. I think you can keep your old 128 sticks as well giving you a total of 768MB of ram.

Cool ok, one more question. Im noticing quite a bit of price variation with the DDRAM, is there another variable to the chips besides them being DDRAM and 128/256/512 ect.?

Nononono, you've got the good shit for Intel processors: RDRAM. Not DDR. Look for RDRAM clocked at 800mhz. From what I can tell given what you posted, that is what your machine takes.

Jesus. An RDRAM system from Gateway. How much did they charge you for that thing? :p

ok yeah i got it straight now... jesus its hard to find RDRAM in my town i had to order some next day air so i could play planetside tonight :) I got another set of 256 chips so now ill have 768 total. that should do me i think.

Thanks for the help guys :D

For future refference use www.pricewatch.com to find the best price on whatever it is you're looking for. And if you don't want to look around just go to www.newegg.com. Newegg is awsome. All your base are belong to newegg.
