Hey

I have a setup with an intel Q9550 and a Asus P5N-D motherboard (using the on-board RAID5 from the P5N-D over 3 1TB disks). Currently I am limited to 8GB RAM. I'd like to upgrade to 16GB if possible.

I assume the chip can handle it, and that the mobo is the part that is limiting the amount of RAM I can use. Is this a correct assumption? If so, is there an available motherboard that supports the Q9550 and 16GB RAM (and preferably RAID 5 as well).

I don't want to buy a new machine unless I absolutely have to. The CPU is more than fast enough and i'll get solid state drives to push up the I/O in a new machine later on. My bottleneck is the RAM right now.

Any pointers?
 
There are but it's hard to find them on web sites because none of the MB manufacturers seem to allow you to list MBs by MAX RAM, sigh.

EDIT: Newegg to the rescue http://www.newegg.com/Product/Produ...ption=&Ntk=&CFG=&SpeTabStoreType=&srchInDesc=

List of boards supporting 16GB ;)

Between the Asus, Intel, Gigabyte & Zotac boards it looks like only the Zotac does RAID but rather check the manufacturers site for confirmation. You can always get a RAID card...

Out of that lot I would get the Gigabyte with the best specs seeing they have the most expansion slots out of all the boards.

I also tried searching around, but not being familiar with which CPU's and mobo's are compatible, I thought it best to ask. I assume my best bet is to phone around then. Thanks ponder.
 
Hope you can find those locally.

Both support 16GB.
 
Don't think so. I saw the link for the "P45SG" which says 8GB max.

Looks like he's going to need LGA1156/ll55? Unless he can find a second-hand LGA775 board that supports 16GB.
 
I'm a bit puzzled as to why you would need 16gig. Maybe check if it really is the memory that will solve your problem.
Which OS are you using?
 
+1 to what Lounger said.

I'm really surprised if you need more than 8GB of RAM, because very few people do. Like I bought my 6GB RAM from someone who had to upgrade to 12GB...
 
To answer the above 2 posts...

Yes, in an ideal world i'd need about 100MB for the app i'm running (probably less). I'm sitting with an application developed by someone else that is chewing up memory (really bad design from a memory perspective). I have 3 choices at the moment (getting the developer that built it to fix the problem is not an option in our case, and we would not want to go that route in any case):

1. Rebuild the system from scratch. I estimate 3 weeks for a complete rebuild if I rebuild it. We're launching a product in less than a month and we need this app running now to assist us with the development of another product, so a rebuild is not an option in our time constraints.

2. Scale up the hardware to accommodate the design flaws temporarily just until we get the time to rebuild.

3. Dig in and optimise the code in the hope that we can find a few bottle necks so that we can keep this thing running until we have time to do a rebuild.

I am currently pursuing option 3 as I have the source code. CLRProfiler is finding a lot of references keeping objects alive, preventing proper disposing etc. I do want to keep my options open though, just in case we can't solve the problem without major changes which would require time that we do not have. Hence my asking for details on hardware - the app currently uses 10GB, and after it hits page file the thing grinds to a halt.

So ya, it's a case of potentially having to deal with that decision that no developer ever wants to make (i.e. use hardware to solve a software problem).

Thanks for all the suggestions in this thread.
 
Who would have guessed that a programmer would write an app that uses 10gig of RAM. Now I've heard anything. It isn't for NASA is it? ;)
 
Good luck finding a new Socket 775 motherboard. All the online retails that I use are out of stock on the Socket 775 motherboards.

The expensive alternative would be to go for the Socket 1366 motherboards that allow up to 24GB, but at least you won't be able to have difficulty finding a motherboard/CPU quickly.

The Sandy Bridge motherboards support up to 32GB of RAM, but once again stock availability of the motherboards & CPU's are an issue.

I really feel your pain w.r.t. the memory issue. Its definitely the cheaper option to buy bigger/better hardware than to wait for the developer to fix the issue, since you can't tell for sure when the developer will be able to fix it.
It took me a couple of weeks to fix some of my memory leaks in C, and it was a relatively small code base :(

Well Matrix have one with a supplier that I can order that will work with my Q9550 and supports 16GB (intel skyberg). I'm hoping I won't need it though.
