Hello,

Just out of curiosity, I was wondering if the EX470 would be able to support a single 8GB DDR2 DIMM.

Does anyone know?

The EX470 will not support 8GB and if you install 4GB the most you would get to use is something like 3.2GB. If your running a 64 Bit OS in your EX470 I am not sure just how much memory the Motherboard can address.

Lets just say if could support 8GB the cost of the RAM would be so expensive its cost prohibitive. The other thing is while not impossible to find its close to it but seeking 1 stick of 8GB DDR2 shows up as ECC and I am not sure the EX470 will support ECC RAM.

The OS has to be 64 bit in order to address anything above 3.2 GB. WHS 2011 can do that because it is a 64 bit OS. The original WHS was 32 bit. As Comp1962 pointed out the MoBo also has to support addressing that much memory.

Interesting. I was wondering the same thing for my EX495 the other day. Even with 4GB installed, WHS2011 eats up 55% of it, sometimes more. I guess if it could be done, you would see systems like that here on the forums.
As Comp1962 mentioned, the only ones I have found are ECC.

You know I installed 8 GB when I built Highlander and ran WHS2011 and the most I recall seeing it utilize was like 2.2 GB or somewhere around that so going from 4 to 8 really would not get utilized unless you were to load stuff into RAM like creating a RAM Drive and I am not sure how you go about doing that but I believe its possible.

Even if you find an 8GB DDR2 stick its probably going to be wicked expensive. Now that I am running WS2012E I am not quite sure I need more RAM but should that need arise my motherboard can support up to 32 GB but this is not to brag its just to point out its not necessary. The other thing worth mentioning is that if your running WHSv1 the server will only utilize something like 3.2GB of the RAM and more if you run a 64bit OS on it.

Hmmm. Well, I found some used on Ebay for $120 - 160, but it's ECC. If I knew it would work, I would give it a shot!

Since I couldn't return it, wouldn't want to gamble. But it sure stokes my curiousity. It's been hard to find anything definitive about this, but as I said, I am sure there would be alot of EX4xx boxes running 8GB if it could be done.

Highest percentage of RAM in use I have seen is around 75%. I have a lot of other things like Remote Potato, Orb, SabNzbd, PerfectDisk, etc, so that takes some too. Sometimes it seems that WHS V1 was faster. Nothing seems very snappy on WHS 2011 on the EX495, even running a quad. Wouldn't go back now though. Benefits outweigh the negatives.

Thanks guys,

I am actually running Windows 2012 Server on my EX740 (2GB ram) and I was wondering to extend its life by adding extra ram (already got a dual core CPU upgrade.

ECC RAM is not compatible with the MSS so please put that thought out of you mind. I have only owned 2 units which could accept ECC RAM. As for giving WHS2011 some juice to speed things up an SSD would help. I did run a 180GB Intel 330 in Highlander and it helped. The one thing I did notice was the amount of time Meta Browser took to load was significantly improved. However is will not speed up everything because the delays will arise when data is being read from your storage drives. I can't comment on the impact of the boot time because Highlander with its Drive Controllers initializing all the drives and the Intel NICs popping up at boot slows the things down making for a rather long boot process which the SSD has no real control over. For OS applications its quick but for OS applications that read from the storage drives the your not going to see any significant speed increase because of the storage drives unless of course your rich and convert them over to SSD's then you would have something very snappy.

ok, ok. But you can't fault us for drooling!

Well, I am running a "green" 2TB system drive. I just want the max storage I can get with the limited drive bays I have. So I guess I will just have to put up the delays. Hopefully I will not have to boot my server that much, so will just have to put up with it.

Thanks for the info.

Hey I know what its like to want to maximize your options and if you are outgrowing you current solution then its time to consider a new solution including building or purchasing a new unit to keep up with your needs. Still the Small Form Factor the MSS offers is very cool and if my needs could work with that form factor I would still be running one of my MSS units as my primary server.

One of the things about the RAM in an MSS is it actually runs at half speed because there is only 1 stick of RAM so that creates a bottleneck in terms of processing things. Sooo if your drawling a lot then it maybe time to go with a new build or purchase a new system to provide you with the growth you may need, want or desire but I tell you honestly if you can stay with what you have and be quite fine with it then I envy you very much.

Well, if you don't drool a little, this isn't the hobby for you!

Seriously, I've always enjoyed trying to get the most out of what I have. (I still run older overclocked desktops) I love the HP MSS boxes. However, I see a lot of users going to the N40L and N54L servers from the MSS. And I have been looking at those but I still think there's a lot of life left in this one. It really serves my needs quite well. But getting parts down the line will be a big factor. Have managed to acquire some spares, but eventually I know they will dry up.

4GB will do the job. I realize it's single channel vs dual channel. Thanks for all the info on the ECC ram.

I can tell you've drooled a lot in your day! Just look at what you're running!

I kinda envy you!!

Guilty as charged and I have closets full of dysfunction toys which help keep the running toys going. I am still playing with MSS units and today is server recovery hell with an EX470 that appears to be drive related even tho the drives I am using have a clean bill of health from HSS. I would buy a new drive but damn I don't want to muck around with AF Drives so I am in my hard drive recycle bin. Have to tell you honestly WHS2011 and WS2012E are much easier to work with these days.

I think you need more closets!

I agree with you that WHS2011 (and prob. 2012E) are easier to work with than WHS V1. I don't think I will miss server restores, or data migrations. Still have a soft spot for V1. It worked well for a long time. I just never felt fully protected from a disaster with it. I mean, when you only got 1 server.....!!

Anyhow, to stay on topic, I will NOT try to get my MSS to use 8GB of ram and will put that thought out of my head!

You know you can always build a new server and put that 8GB in it. I have one server with 16GB of ECC RAM which is in it because I could put it but not that its actually utilized. The only benefit I can see to installing large amounts of RAM in a system is to use the extra RAM as a RAM Drive. I use to use a RAM Drive back in the 80's and 90's to store the BBS Software to speed up the BBS I was running which increased performance significantly.

How one could configure and use a RAM Drive to run the Servers is something maybe worth looking into but its been along time since I have ever played with a RAM Drive.

Folks,

So I finally for 4GB today and installed it. The only problem is that my OS (64bit Windows Server 2012) reports 4GB but says that only 3.34GB is usable (yes, it is 64bit).

I tried playing with the boot settings on msconfig but that didn't do the trick.

I was wondering if anyone here is aware of any memory hole/remapping/etc setting in the BIOS (I have a VGA cable) that could sort things out?
