What kind of RAM on the IFL90?

I think I will buy 1 stick of RAM from the reseller and buy the other stick from a cheaper store. However, I dont know how common the IFL90 ram is. I have 3 questions:

1. Does the Compal IFL90 use this kind of ram: (and if not, what does it use)
240 PIN DIMM DDR2-800 NON-ECC 1.8V

2. Will I benefit from 3 Gb of RAM over 2 Gb? Will my laptop be more futureproof If I choose for 3Gb? (please don't say things like: "Don't choose for a laptop when you want a futureproof computer")

3. Will there be a performance boost when I use 800 MHz RAM over 677MHz RAM?

 

1. The IFL90 uses 200 pin DDR2 modules at 533/667MHz.

2. I don't think 3GB is all that useful yet, but down the road it will be.

3. There is no need to use 800MHz RAM, and I don't think it can support it anyway.

 

(3. ) You think not? I was thinking that, because the FSB speed of Santa Rosa is 800 MHz, the RAM can be that speed too (the numbers are both 800, that's why =) ). I was also thinking this because the reseller in my country now also sells 800 MHz memory sticks and a few memory sellers also sell them since about 2 weeks now.

 

1) No that ram will not work. You will need something like this. 200 pin DDR2 SO-DIM 667MHz PC2 5300.

2) I would probably get 3 GBs since Vista is a ram hog.

3) Santa Rosa does not support 800MHz ram so you will not see a performance boost. Just get 667MHz ram.

Thank you both very much!

 

The north bridge (Buss between CPU and MB) is 800mhz. That I'm pretty sure on.

Is it south bridge the other buss is called? (to ram and other stuff). Anyway, this buss do I think that is just 667 mhz. But I havent managed to get this confirmed. Is there anyone that now this for sure?

EDIT: Tim did well just there cofirm it

I am not a Laptop expert so please somebody explain this: If the new SantRosa platform is 800 Mhz, why will it Not support 800 Mhz RAM. And if it will not support 800 mhz RAM, so what's the use for Sant Rosa?????

 

Here's a pretty neat explanation I read in another thread:

I also remember reading in some reputable hardware review site (but I don't remember which exactly) that the Santa Rosa chipset is evolutionary but not revolutionary. In other words, yes it is better but not dramatically so.

 

xotic sells the IFL90 with pc6400 (800mhz) ram,
and its 2g of ram and 1 of robson? or 3g of ram,

I would get robson (3g total) well IMHO

 

You shouldn't compare system memory to the robson drive, really. Robson is a lot slower than system memory but a lot faster than a hard disk drive. I think you'd better take the 2G ram and 1G robson.

 

Do you lose dual channel with one 2gb stick and one 1gb stick? And if you do, is there a performace hit or does the extra ram make up for it?

 

Wait,robson would take up one of your ram memory slots?

 

robson does not take up a memory slot, and having robson is not the same as having 3 gb ram. anyway, dual channel is much less important than having more ram.

 

I would go 2gb + 1GB Robson, 3GB of DDR2 Ram i don't find useful currently. You can always upgrade to 3 GB later.

 

By the way, remember that Robson can only work with Vista right now. Neither XP nor Linux support it at this moment.

 

Unless a 3rd party writes the drivers I'm not expecting Robson will come to XP since the functionality is something from MS, and not Intel...

And I don't see MS giving XP one of the only good features from their new money maker..

 

From the link here, xoticpc only offers 667 MHz RAM for the IFL90: http://www.xoticpc.com/product_info.php?wconfigure=yes&products_id=1983

Robson's isn't RAM or a RAM substitute.

 

Currently, the PowerPro J 10:15 (Compal IFL90) is only being offered with DDR2/667 memory.

Taelrak is correct, Robson is not system memory or a system memory substitute, rather it is a memory enhancement. It should not be considered part of the total system memory. Rather it should be stated as, for example, 2GB system memory plus 1GB Intel Turbo Memory (code name Robson).

 

I am sorry to dig up this old thread but I want to be sure what memory fits in the Compal IFL90.

Does this memory work with the IFL90 (2GB MEMORY MODULE STD 200P DDR2 667 SO-DIMM). I am not sure about it because I was advised to buy "PC5300" memory. Although this memory matches the other specifications mentioned, the description doesn't name "PC5300".

What does "PC5300" mean and does this memory work in a Compal IFL90?

I am looking forward to your answers.

 

Will there be a way for XP to support Robson in the future?

 

Not necessarily. Some chipsets can do asynchronous dual-channel, so the first 1GB of each stick is in dual-channel. I don't know of the 945PM or 965 chipsets will do so, though. And the performance hit is ~5% in real-world usage, and that's only RAM bandwidth, so the actual change is negligible unless you're doing large, long scientific calculations that are memory intensive.

No. It will possibly work as a flash drive under XP, but it will never work as the page-file caching speed-up mechanism like it does under Vista. You MAY be able to put your page file on the Robson memory, which would possibly speed things up, but not to the level of tuning that Vista does.

 

You do give a lot of information, Pitabred. But it was an answer to Stocom's question, which was quite off-topic.

Do you, or anyone else, maybe know the answer to post 19?

Thank you for your replies.

 

I should work since it is the correct type, but until you test any memory in the computer for which it is intended you never know for sure.

PC5300 (or sometimes called PC5400) memory is just another name for DDR2/667MHz memory. It comes from 667MHz x 8 = 5,336. Some vendors round down to PC5300, some round up to PC5400.

 

That's exactly what I needed to know. Thank you very much!
