Some RDRAM background questions

[OfficeLinebacker]

Exactly what my options are.

Right now it has 512MB--2x256 PC600 plus 2xCRIMMs.

Is it possible to buy one 256MB stick, replace one of the CRIMMS, and run like that at 768 for a while, then maybe get another 256MB RIMM later?

Also is it OK if said new stick is PC800? (I presume the MoBo will automatically de-clocl it to PC600?)

Also, I presume PC1066 is out of the question? (Not that I would normally buy it, but say I found some great deal on it, would it work (declocked of course)?

So the 4 slots can be thought of as 2 pairs....each pair must be matched in terms of size, no? But is is it possible to do 2x256 in one pair and 2x512 in another for a total of 1.5GB?

I got this MoBo/CPU combo kind of by mistake, but am trying to make the best of it. Freaking RDRAM and the constraints for use!

Rambus has to be installed in identical pairs. Also the speed is automatically "DDR." This is why you have to install in pairs. Also, IIRC (its been a while since i messed around with rambus) all modules need to be identical--ie, 4x256, 4x512, etc. Thats how i did it anyway.

Also, rambus is often faster than ddr, but its more expensive. So, dont be hatin on rambus.

When faced with the cost of upgrading their RAMBUS motherboards (most of which are several years old now), many people decide to hand the computer off to a relative and buy a new computer (or motherboard) that doesn't use RAM that costs the same as gold.

Dont think so, but ill try it out for you

PC800 are 16bit, PC1066 are 32 bit. I heard they dont work but some website seems to think so.. someone should know here..

yes, you can do that.. I actually have a rambus slot expander, that use 2 slots and expands it to 8 rimm slots.. yes rambus sucks

exactly.. i sold 1gb of rdram for around 200 on ebay... i had 6 gbs, sold 2 gigs a few months ago, selling more now.. ebay 6835651175 just went for 242.. the rest of the junk are going asap

sold my old rdram and bought x2 3800 mobo + cpu

I agree that it's kind of a PITA, but the system is set up and running fine with OS installed.

still exploring my options. Little Veg, if you could try that out I would appreciate it.

Well, 512 should be enough for wahtever you are using that system for.

Otherwise, sell and rebuild.

Must be installed in pairs. eBay is your friend for these kinds of items.

i have a RDRAM rig with 768

it uses PC800 Samsung RIMMs and i think it set like this...........

2x256 and 2x128

 

[OfficeLinebacker]

Well I see 256 RIMMS for $40 a pop on FS/FT, I may just get two of those and get 1GB total. that's not bad.

too bad u did post earlier.. would have given u 2 free 256s.. i listed them on ebay few days ago
