9262 8gb RAM

Does anyone have 8gb of ram in their machine? If so what brand and where did you get it from?

thanks!
Og

 

only ppl i know that have that options is PCMW... 4gb is fine anyway unless your actually using the machine as a server

 

I really think it's unnecessary to have 8GB as of now..

 

I don`t think anyone has 8 GB of ram in any D901C , but (I`m not sure on this one) as far as I know, it can only use up to 4 Gb...

 

ok people.. i didnt ask your opinion on if you think i need 8 gig... i asked to hear from those that arent 12 years old and only play video games with their machines...

i thought i saw a post somewhere that said someone ordered their machine with 8 gigs... im looking for who made the chip so i can look it up and get some for myself....

btw...

i run Zbrush and Maya.... they BOTH can use MUCH more then the 4 gig i currently have....

 

What you probably saw was for the Edge laptops.
The D901C uses a stripped down version of a desktop mobo and uses max 4 GB.

 

so you are saying that you need a specific MB revision in order to use more then 8gb?

 

www.pcmicroworks.com the blackhawk you can get up to 8gigs... and plz dont be mean... nobody hear is under 12 and we all do more than just play video games...

 

Ogg, I would recommend that you Google for 4GB pieces of DDR2 800MHz SODIMMS.

I would also recommend you keep your personal insults to yourself...they have no place here.

 

Ogg, also, to answer your yet to be asked question as to why no one but PCMW offers 8GB memory, it is because the Intel P965 chipset only has a maximum of 8GB addressable space, a good portion of which is necessary for hardware, so only about 6GB +/- will be usable for applications.

 

We too have offered 8GB RAM for a while (it's actually not been around for that long, 4GB SODIMMs that is) - there is a market for more than 4GB RAM in many applications as Ogg as pointed out. If you have trouble finding it on the internet it would be worth contacting your "local" Clevo reseller - we sell spare parts etc over here and PCMW might sell you 8GB if you want it (if you're in N America!).

I'm going to word this carefully as I don't want it to be taken the wrong way . Ogg didn't ask why no one but PCMW sells 8GB in the 9262/D901C - he asked where he could get it from. There are several companies including PCMW and us that offer 8GB - it works and there is a market for it or we wouldn't offer it.

EDIT: 8GB is 667MHz not 800MHz

 

My, my; if you're only getting replies from 12 y.o's perhaps there's a reason for it.

Yes, as a little bit of diligence - like a forum search on the phrase 8GB RAM - in reviewing the forum posts would have demonstrated, the D901C can support up to 8GB of physical RAM; however, as justin@xoticpc explained (with supporting documentation from Intel ) in this post, you won't get to see all 8GB because the P965 chipset has a limitation in its address space that only allows it to have up to 8GB of addressable memory - since some of that is set aside for addressing peripherals and whatnot, total available RAM will always be less than 8GB.

Now, neither Sager nor, more importantly, Clevo, appear to have publicly stated as much about the D901C, which is not necessarily either here or there, since both tend to have a very virtuous streak of conservativism in their marketing claims, and, as far as I know, no complaints or issues regarding using 8GB in a D901C have shown up on the forum. That means that, if there are any issues, they most likely occur significantly less than 50% of the time.

Finally, why doesn't Sager offer 8GB? Firstly, probably because Clevo hasn't said anything public about supporting 8GB and Sager seems to have a lot of respect for Clevo's public positions, or lack thereof. And, as goes Sager, so go it's resellers, including xoticpc and powernotebooks.

Secondly, probably because there's not much of a market for it at present. As you no doubt know all too well, notebooks are both more expensive and less powerful than desktops, so it's quite likely that, as a general matter, if someone really needs 8GB of RAM, they're going to be putting their investment into a desktop, not a notebook, so the pressure to offer such an option is particularly tepid right now.

At the end of the day, it's not an item that's particularly in demand right now. As an alternative to checking with a reseller, why not check with the memory manufacturers - at least with PNY, you can buy direct - the resellers, and, if all else fails, google it to find someone you can order from.

 

As I said in my post #10 above "...the Intel P965 chipset only has a maximum of 8GB addressable space, a good portion of which is necessary for hardware, so only about 6GB +/- will be usable for applications."

Neil, I stand corrected ...at this time it appears that only 667MHz 4GB pieces are available in the marketplace...but that doesn't mean that "8GB is 667MHz not 800MHz", it only means that there doesn't seem to be any 800MHz 4GB pieces available yet. That is bound to change at any time.

Now, while I appreciate Shyster1's excellent speculation about why Sager does not offer 8GB, let me clarify their position.

Since we know that even if you install 8GB DDR2/667MHz memory (2x4GB) you will not get more than 6GB +/- that will be usable for applications due to the chipset's 8GB total addressable limitation. The graphics card(s) alone will be using from 512MB to 1GB of the 8GB addressable capability of the chipset, and other hardware components will also be using smaller amounts of the addressable total.

The price of an 8GB kit is around $900-$1,000. See for example Kingston's site ...others may be higher or lower ( ah, finally a real answer to Ogg's original question ).

So it is no wonder that the upgrade price from 4GB to 8GB at Kobalt is about $835 (426 GBP) and at PCMW the upgrade is $1,185 for DDR2/1333MHz (which we have already established does not exist...and even if it did the 9262 will only support up to DDR2/800MHz. See Intel® P965 Express Chipset specifications..."...Intel Fast Memory Access also includes wider internal data buses that support dual-channel DDR2 memory technology at 800 MHz...".

It would seem that paying that much to upgrade from 4GB of physical and totally addressable memory to 8GB of physical but only 6-7GB +/- of addressable memory for applications (particularly without a proper explanation that you will not be getting your full 8GB of addressable memory available for applications) is excessive. This of course excepts those like Ogg who can afford to pay $835-$1,185 for an additional 4GB of memory of which they can only use +/- 2 to 3GB.

I realize there are those like Ogg and some of Neil's customers that can both use and afford (or just want and can afford) as much memory as they can possibly get. However as Shyster1 suggests they are a distinct minority, and Sager simply does not offer it for all of the reasons stated herein.

 

Everything paladin44 said! Look at the 4GB 32bit OS issues? Talk about an Excedrin headache! Microsoft got so sick of explaining until they were blue in the face. They said fine Vista SP1 let us show them what is installed not what the OS sees/can use! But oh boy! Now everybody is oh so friggin happy? Nothing changed. Ignorance is bliss for some but a headache for others. And to make clear those who paladin44 pointed out I do understand they are not who I am talking about. I am talking about the masses.

 

Paladin44 is too gracious by far - he always does a much, much better job of explaining the point than I do. Thanks for the info Paladin44!

 

We treat it in the same way as Windows 32 and 4GB RAM - 99.9% of the time our customers ring up before ordering the more expensive D901C notebooks and we always point out the 8GB "issue", Windows 32bit/4GB RAM, suggesting backup solutions for RAID 0 whether internal or external etc etc. I don't know how other companies look at it but we could have offered 6GB (1 x 2GB DIMM and 1 x 4GB DIMM) but that wouldn't be running in Dual Channel mode so we go straight from 4GB-8GB. The 4GB DIMMs are expensive but we're not taking money off people "blind"!

When I said "8GB is 667MHz not 800MHz" I was of course talking about the RAM available at the moment as the post said "I would recommend that you Google for 4GB pieces of DDR2 800MHz SODIMMS"

 

Quick question Neil: In the 6GB configuration, wouldn't the RAM run in dual channel mode as to 4GB (the full 2GB stick being matched up with half of the 4GB stick) and only run single channel as to the remaining unmatched 2GB in the 4GB stick?

 

To run in dual channel both DIMMs need to be the same size e.g. both 1GB, both 2GB or both 4GB - in the same way that in a desktop with 4 DIMM slots and a total of 4GB RAM, 2 x 2GB DIMMs would be dual channel but 1 x 2GB with 2 x 1GB would not. It's a case of yes or no, not half and half

 

I believe that the P965 chipset used in the D901C is capable of supporting Intel's so-called "Flex Mode" memory management system, which allows dual-channel to be used up to the size of the smaller memory stick, with the unbalanced remainder being operated in single-channel mode. See, e.g., this Intel discussion (at least with respect to the Intel desktop mobos described in that article).

Also, the subject is discussed in the context of notebooks in this NBR post.

A detailed discussion of this topic can be found at http://www.intel.com/support/motherboards/desktop/sb/CS-011965.htm

Take a look at the Flex mode section. You will see that the P965 chipset does support Flex mode that allows Dual Channel operation with different size pieces of memory. Just as Shyster1 described:
"The figure below shows a flex mode configuration using two DIMMs. The operation is as follows:

* The 512 MB DIMM in the Channel A, DIMM 0 socket and the lower 512 MB of the DIMM in the Channel B, DIMM 0 socket operate together in dual channel mode.
* The remaining (upper) 512 MB of the DIMM in Channel B operates in single channel mode."

We are checking with Clevo tonight to confirm whether Flex mode is enabled, or can be enabled, in the D901C (Sager NP9262) and will report back the answer tomorrow.

However, with all that being said, I would certainly forego the minimal benefit of dual channel operation if it would save around $500 by only installing 1x2GB and 1x4GB...instead of 2x4GB

 

I have now confirmed that the D901C does support Flex mode.

First picture = 1x2GB + 1x1GB in Dual Channel
2nd picture = 1x2GB in Single Channel
3rd picture = 2x2GB in Dual Channel

 

Not to toot my own horn but here is a sticky that has some basic explanations for the kids who want to know a little more, link.

Also from my reading but cannot find right now. Just like what is determined to be less likely to be used gets bumped from RAM to disk. Hopefully minimizing HDD hits. Well it is my understanding in the Asymmetric Dual Channel what is decided is more likely to be used migrates to the front thereby in many situations RAM being used is all coming from the Interleaved part minimizing the performance hit. With 6GB you would for the most part need to be using more than 4GB to face the penalty. In mobile chipsets Intel. Dual Channel is a 10% increase in bandwidth, the 6GB (or even 3GB) gives a 7%. That is in proportion to the matched amount vs unmatched. More in link.

Yes, Shyster1 linked to your guide in his post #20 on the previous page.

That is a fantastic guide...now if only more people would read it

 

Regrettably, that can probably be said about most of the forum!

 

Allow me to correct it:

Googled 4GB pieces of DDR2 800MHz SODIMMS as you said, and thats what I found .. does that mean that it might be true that PCMW does have the D901C with 8GB/800 GHZ? -confused-

or is that for desktops? ><

 

D901C only supports up to 8 Gb ddr2 677 and not 800 I think. Also, there are lower end upcoming models that support up to 8GB DDR3-1333 !!! but not the flagship D901C???

thanks

 

Those are for desktops. Laptops use SODIMMs.

 

At this point in time the fastest Centino laptop memory support available is 667MHz (See http://www.intel.com/products/chipsets/pm965/index.htm). Once Montevina is released next month and then Centrino 2 in August that will go up to 1066MHz. Anyone claiming otherwise is simply not telling the truth.

The D901C uses the desktop P965 chipset that supports up to DDR2/800MHz. Go back and carefully read my post #14 above. Anyone offering anything higher is also not telling the truth.

Please do your homework by researching what chipset any laptop has, and then go to the chipset manufacturer's website to verify what it will support instead of just assuming that because some online company, that refuses to allow anyone from the public to visit them, says that they offer it that the laptop can really support it. There have been many companies like that come and go...and the one thing they all seem to have in common is that they end up disappearing...some sooner than later.
