PC1066 RDRAM?!?!?!

[Vince604]

Just wondering if anyone knows when PC1066 RDRAM will be coming out and can give some details about the modules like what companys will make them and how much 1 module can hold....

Thanks

Samsung has some floating around, but it's not publicly released yet. It'll release around the same time as the 133(533) P4.

Alright thx.
Would you know how much one module could hold?

 

[FatBurger]

You mean the maximum size in MB?
Most likely that would stay the same (512MB), since it's only the clock speed changing.

[Vince604]

Yup exactly. Thanks. So you think that will be bundled with the Asus P4T533?...

Even if you have a dual channel motherboard would it still be possible to just use one slot and not go dual?

 

[ath0mps0]

No, i850/860 MUST be run as dual-channel.

I thought a thought, but the thought I thought wasn't the thought I thought I had thought.

 

[Vince604]

Ok then thanks. So if I just use one slot instead of two my computer won't start up then?

 

[FatBurger]

Basically, yes.

Wait...you're not confusing PC1066 with 32-bit RAM, are you?

[Vince604]

What you mean?
When I get the Asus P4T533 I'm going to want at least 512MB PC1066 RDRAM to start off with.. But the mobo uses a dual channel for RAM so I was wondering if I can just use one slot and leave the other 3 empty and not going to have the dual bandwidth...

 

[Harisahmed]

RDRAM only runs in dual channel, therefore if you want to have 512MB you will have to use 2x256MB sticks. This was the main reason why some people don't like RDRAM.

 

[Vince604]

I see. Well what is the most ram that someone can ever use? I'm not sure if 512mb is enough or just to get 1gig and not have any future problems with ram upgrades...

 

[FatBurger]

There are however 4 slots, two per channel.

[Vince604]

Yes I know.. But not sure how much ram I would really need... I mean the Asus P4T533 supports up to 2GB of ram and not sure if I should get that much or it would be a waste of money if I could never use that much ram anyways... So just wondering if you can ever use up to 2GB or even 1GB of RAM........

Actually, the new P4T533 board has 2 PC1066 RDRAM slots. You can have JUST ONE of the PC1066 slots with memory in, and the other one empty and the board will boot fine. One PC1066 pcb is actually the same as a dual-rdram, just that they are stuck together more/less.

So the answer to your question is that you do not need 2 peices of PC1066, they are actually already paired up on one memory pcb.

 

[bum_jcrules]

This is correct...

<A HREF="http://www.rambus.com/company/press/pressreleases/2002/020225a.html" target="_new">"The RIMM 4200 uses the 1066 MHz speed bin of current production RDRAM to deliver the highest performance available to date from a single PC memory module," said Tom Quinn, vice president of Marketing, Samsung Semiconductor, Inc. "A single module that supports two channels of RDRAM with 4.2GB/sec of bandwidth makes RDRAM even more attractive from a price-performance standpoint."</A>

[Vince604]

Whoa that's awesome!
Thanks you guys.

So by just putting in one stick of PC1066 RDRAM it will still run on at 4.2GB/sec without any problems?
Seems kinda awkward but at the same time perfect..

 

[Harisahmed]

Thanks for the update. What kind of price difference is there between PC1066 and PC800, for say 1x512MB?

 

[FatBurger]

PC1066 isn't out yet, nobody knows.

[Vince604]

Well I think it comes out in May since the Asus P4T533 will have bundled PC1066 RDRAM but I'm not sure if they will be selling them in seperate pieces at the same time?...
Can anyone clarify if they will be selling just PC1066 RDRAM at the same time or are they going to be only bundled with the new mobo?

 

[Kennyshin]

It's 4200, not 1066. They call it "RIMM4200."
As to the bundling, it's the same situation with the first generation of RIMMs with i820 and later i850. After a few weeks to a few months, the 232-pin RIMM4200 modules will be on the mass market, too.

[Vince604]

Isn't it also PC1066 RD-RAM?? as it stands for the speed at 1.066GHz?

[ath0mps0]

RDRAM vendors are simply doing the same thing as DDR vendors - PC1066 is the bandwidth per pin in megabits per second for the RDRAM devices. RIMM4200 represents the bandwidth (4267MBps) of the entire module in megabytes per second. The same is true for DDR-SDRAM: DDR333 represents 333Mbps/pin on the chips while PC2700 represents 2667MBps for the DIMM module.

I thought a thought, but the thought I thought wasn't the thought I thought I had thought.

 

[Vince604]

Alright then.. Nothing special but names then eh?

 

[Kennyshin]

Not truly.

PC1066 RDRAM is 184-pin 16-bit as far as I know.

RIMM4200 is 232-pin 32-bit modules. Asus 850E-based P4T533 has only 232-pin slots. I think that is why the motherboard will be supplied bundled with a RIMM4200 module. 32-bit RIMM4200 can be used in single configuration. There will also be RIMM4800 (equivalent to PC1200 dual channel memory bandwidth) and then 64-bit RIMM9600 (with 9.6GB/s memory bandwidth.)

I'm not sure if everything I said above is true. Correct me if anything's wrong.

[Kennyshin]

Nobody has yet experimented with 2GB 4.2GB/s memory in a PC system. If the price is low enough, I will have 2GB RIMM4200 in every system I use. RAM drives are especially good with higher bandwidth and faster access time.
