Samsung RDRAM - SS or DS?

[RhoXS]

I am placing an order with GoogleGear for an Abit TH7-II, 1.8G Northwood and 512 MB of RDRAM. GoogleGear has two choices listed, as follows, for Samsung 256MB RDRAM sticks.

256K x16*32s Double sided at $80.00 per stick
GoogleGear 80445-1 / Samsung MR16R082GBN1


128Mx16*32s single sided at $76.00 per stick
GoogleGear 80445 / Samsung MR16R1628AF0

Since the $4.00 difference per stick is negligible, how does one decide which is the better choice? It is every bit my intention to overclock the 1.8G P4 to 2.4 G.

They also have a Kingston 256MB stick for $89.00. Is there any reason to consider the Kingston stick over the Samsung? The price differentials are sufficiently small that my overriding concern is good quality memory that will reliably support overclocking the 1.8G P4.

i just came here to ask that EXACT same question! (same vendor, same mb, cpu and mem!) Someone help up out? Also, does it seem crazy to anyone else that RDRAM is actually cheaper than quality DDR right now? (Or at least that it doesn't make sense to spend $100 on pc2700 to approximate the performance of RDRAM?)

256k (I do belive they meant 256mb) double sided.

I can't help, but was thinking along the same lines.
Have been away from the OC scene since I built my 266/450 celeron and are ready to go again. Would like to find out how both of you make out with your rigs, and googlegear. Just registered and read something about posting in the correct location, but it seems like more people are looking at the Intel CPU's forum.
I still have not decided if RDRAM is the way to go. Lots of articles on OC indicate it is sensitive to clock increases. The posts on this forum and the CPU Database indicate otherwise! Because of the bandwidth advantages and price parity would definitely be the way to go if it does indeed clock reliably.

Abit TH7-II, 1.8G Northwood and Sumsang 512 MB of RDRAM
i have the exact same specs
Sumsang overclock well, i never liked kingston that much

Welcome to the forums, and the addiction, DK! Now that price parity has been acheived, even sometimes giving the price advantage to Rambus, I'd say they're the way to go on a PIV system... The only price factor is the motherboard, which are very close if you go with a high quality board, and the fact that you have to do Rambus in pairs...

ur all off topic!
i think the SS and DS difference might be heatsinks, if its SS then its easier to put bigger heatsinks on each ram chip rather than smaller ones on both sides. thats what im thinking

Not at all, I've seen SS with heatsinks :) .. Anyways, I'm using DS samsungs on my prev board, I've heard that SS is actually faster for OCz, but to be honest, RDRAM is picky with O/Cing, this is what I've experienced in the past 2 weeks, and that's why I jumped to PC2700 DDRs! Back to your topic, I think SS will do you better O/Cing.. This is just MO :)

in my experiences RDRAM overclocks better

[trey_w]

single sided means that the memory chips are on only one side and there is only a single heatsink on it

[dgunthert]

Being new to the overclocking game, I'm struggling with the same question about DDR vs RDRAM. My question is, what's the 2700, 2400, etc, refer to on DDR?

[RhoXS]

Thanks, but are there any advantages/disadvantages between single sided and double sided designs?

I already ordered the memory, mobo, and CPU. I decided on the single sided but basically flipped a coin to make this decision in the absence of anything else to go on. However, I guess that all newer designs will be single sided and performance wise there is no difference.

[RhoXS]

dgunthert, DDR and RDRAM(aka RAMBUS) are different types of memory. The issue here concerns RDRAM only and addresses how it is physically configured (single sided or double sided). The choice between DDR and RDRAM is made for you by the mobo/chipset you are using as each chipset is only compatible with a single type (e.g. SDRAM, DDR. RAMBUS, etc.) of RAM.

Hope this clarifies it for you.

I would say that getting all your sticks double, or all single, may be better.

You can do a search yourself on samsungs site for the data sheets of both models.....
.....you'll find that the SS Rimms have higher density modules. I'd stay away from them purely from a clk rate standpoint.

DS modules have a small BGA package and I believe will better allow higher clk rate as a result.
