Reg:- RAM Upgrade for Solaris v480

Hi All,
Thanks in Advance for sorting this out.
We have 5 Solaris servers on Solaris 9 & 4 CPU's in a cluster. We currently have 48 GB RAM in all the servers. We are planning to upgrade the servers to108 GB RAM.
The below mentioned is the configuration of the servers. Please update on the upcoming RAM.
CPU Current RAM Upcoming RAM
480 8
480 8
490 16
440 8
440 8
Is there any maximum RAM limit set for the Solaris servers.
Please Advice. Quick Response is Appreciated.

I think you're a little confused as to what you already have - but here's what you can actually have in each system...
V480 - max 4 CPU (dual core = 8 cores, not 8 CPUs)
Memory
8 memory slots (DIMMs) per processor, 16 total slots per CPU/Memory Board
256-MB, 512-MB, or 1-GB expansion (16GB maximum per CPU/Memory board, 32GB maximum when configured with 4 processors)
Note: Install DIMMs in groups of four. 1050MHz & faster CPU/Memory boards require that all memory DIMM slots be fully populated.
V490 - Max 4 CPU (dual core = 8 cores, not 8 CPUs)
8 memory slots (DIMMs) per processor, 16 total slots per CPU/Memory Board
512MB, 1GB, or 2GB expansion (32GB maximum per CPU/Memory board, 64GB maximum when configured with 4 processors)
All memory DIMM slots must be fully populated.
Hope that all helps - you can find the hardware specificatoins for each server at http://sunsolve.sun.com/ under the http://sunsolve.sun.com/handbook_pub/validateUser.do?target=Systems/SunFireV480/spec and http://sunsolve.sun.com/handbook_pub/validateUser.do?target=Systems/SunFireV490/spec

Ram upgrade for mac Book Pro mid 2009

Hi, I just bought 2x Kingston 4GB ram upgrades for mid-2009 MacBook Pro. First I don't notice any difference in speed. Second, the computer (in about this mac, activity monitor) doesn't seem to acknowledge it now has 8gb of ram not 4gb. Why would these be so?

You should be able to install 8GB I would check to make sure it has a secure connection. Maybe one of the RAM sticks is bad, or the port itself is bad.

They both state that they can support up to 8GB of RAM.

Where is the cheapest place to buy 8gb ram upgrade for my early 2009 iMac?

Where is the cheapest place to buy 8gb ram upgrade for my early 2009 iMac, I have bought before but current upgrade is causing mac to crash randomly!? Need to know a place I can buy Ram which is confirmed to work my my mac model, the current upgrade is working but Mac is very unstable.

I meant more reasonable priced than apple
That'll be almost anywhere else then!
Yes, if it is made by Crucial and confirmed as suitable for your model of mac you will be fine. You can also buy direct from Crucial:

which is what I would do (did).

Hard Drive and RAM upgrades for latest 15" MBP

I'm minutes from ordering a new MBP. Only concerns are whether I get hte Apple upgrades or shop around.
I like this Hard Drive...
http://www.compu2000.com/index.php?l=product_detail&p=6433
And this RAM upgrade...
http://www.a-power.com/product-10937-311-4
If these are equivalent to the apple options I can save hundreds and get a 320 GB drive, which will make a great portable.
So, does my plan hold water?

You're on your own for support when you do your own upgrades like this, but generally speaking, it works fine.
Note that HDD is less risky than RAM. With RAM you run the risk of unstable behavior that is tougher to diagnose. That said, a quality RAM upgrade and some initial testing with any of many available tools is as good as a factory build.
HDD upgrades are less risky, and I've upgraded (well, replaced after HDD death) ones in my MBPs many many times. I crunch my hard drives more than normal and have to generally replace them about every year. Some of the MBPs don't make this easy, and prepare to get all sorts of cozy with little 0 and 1 sized Phillips screwdrivers and some T6 as well, but it is doable (just not quite for the truly faint of heart).
Again, you're on your own for support once you do this, so weigh that in your decision.

Cost/benefit of RAM upgrade for iMac G5 2 GHz from 1.5 to 2.0 GB

Equipment: iMac 20" 2.0 GHz, 250 GB HD, originally 500 MB RAM upgraded to 1.5 GB: (1) 500 MB and (1) 1 GB DDR SDRAM, PC3200U-30330.
Not understanding the subtleties of memory upgrades, I bought this off the shelf with 500 MB RAM. When the processor board was replaced, I added a 1 GB RAM and can't say I noticed any change in performance. It does reduce the need for page outs.
After this, I read something about needing to have the DIMMs matched for there to be a performance gain. Or maybe this related to 64 bit operation? I read elsewhere in the Discussions that 64 bit operation would actually consume more memory and reduce performance.
If I upgraded to 2.0 GB, would there be any improvement in performance? In general or only in certain situations?
If I upgrade RAM, I'll have (2) useless 500 MB DIMMs. Is there any value in these? Where is the best place to sell them or do they have value as trade-ins?
Or is the best use of the money to put towards an Intel Mac that can support 10.6+ ?(...or a share or two of Apple stock.)
Please convey your wisdom. Thanks.
P.S. I know the stock is the best use of my money, so just consider the hardware options.

I happened to find this answer while looking for something else.
iMac G5 and iMac G5 (Ambient Light Sensor): Benefit of using matching memory modules (RAM) http://support.apple.com/kb/HT2708
Condensed version:
Applies only to original iMac G5 and iMac G5 (Ambient Light Sensor).
*If it has matching DIMMS it operates with a 128-bit data path, otherwise it uses a 64-bit data path.* A 128-bit data path allows greater throughput than a 64-bit data path. This allows faster manipulation of large files. With a 128-bit bus, you would see better performance when you have multiple applications open at the same time. Also, some enhanced gaming performance.
According to this, I was getting better performance before I added the 1 GB of RAM, except that degraded performance due to stuffing RAM to the gills has to be weighed against that. Seems like trading up to a full 2 GB would have some unquantified benefits. The only ways to find out are to find another iMac to compare with or to put in the RAM and see what happens.

Happy to report (Ram upgrade for Mac mini))

Hello All,
I would like to share this info with you, just in case someone wanted to add more Ram to their Mac mini.
I purchased 2X4GB Kingston DDR3 Ram and followed instructions that I found on YouTube and other sources to replac my 2GB Mac mini.
The Kingston ram is very cheap KVR1066D3S7/4G but you should evaluate how much Ram you will need.
If I knew that I will only need 4GB then I would have saved my money in a warmer place (my pocket).
Anyway here is the info of my Mac mini after the RAM upgrade:
Hardware Overview:
Model Name:          Mac mini
Model Identifier:          Macmini3,1
Processor Name:          Intel Core 2 Duo
Processor Speed:          2 GHz
Number Of Processors:          1
Total Number Of Cores:          2
L2 Cache:          3 MB
Memory:          8 GB
Bus Speed:          1.07 GHz
Boot ROM Version:          MM31.0081.B06
SMC Version (system):          1.35f0

I'm not sure what your point is here. How does one actually "evaluate" how much RAM you think you need?         I think most would agree that a RAM upgrade is one of the best performance boosters for the money and the simple rule is the more RAM the better. I have a new Mac Mini with 2.3 GHz i5 processors and upgraded to 8GB of RAM from Crucial.com (complete with instructions so you don't have to search YouTube) and noticed an immediate performance increase when working with multiple applications and while playing iTunes, etc. The Crucial upgrade was only $59.99 for 8GB kit and I think the 4GB kit was only $20 cheaper so it doesn't make sense to not get thte 8GB kit.

Maximum RAM upgrade for Mac Mini mid-2010?

Hi,
I have a Mac Mini mid-2010 (Model 4.1). I purchased it with 4 Gb RAM, and I am now considering a RAM upgrade.
I currently am running OS 10.95 - and not particularly happy with the sluggish performance that has been the hallmark of my 'upgrade' to Mavericks on this machine. I figure that increasing RAM can only help what has become a sometimes teeth-gnashingly slow computer.
In any case, the Apple tech specs document says that the maximum RAM for this machine is 8 Gb. However, the macmemory.com web page for this model Mac Mini says it can handle 16 Gb so long as the OS is 10.7 or greater.
Is this true? Anyone tried this?
Thanks,
HJ

RAM upgrade for MBP 2.2 GHz Intel Core 2 Duo

I have a MBP 2.2 GHz Intel Core 2 Duo currently with 2 GB of RAM and with all the work I do on it I would like to upgrade to 4 GB. Purchasing the RAM through Apple is out of the question because it so expensive.
I would like to know what is the best brand to buy and on what website.. Is an upgrade to 4 GB possible for my MBP? It looks like I have my "Bank 0/DIMM0" filled with 1 GB DDR2 SDRAM 667 MHz and my "Bank 1/DIMM1" filled with the same thing. Does this mean that both of my RAM slots are full AND if I want to upgrade my RAM I'll have to purchase 2 sets of 2 GB RAM? Please help as I am new to all of the tech stuff...
Another side note... I've noticed that some discussions have stated that some MBP are only upgradable to 3 GB of RAM, but I'm pretty sure that I can upgrade mine to 4 GB of RAM. Can anyone shed any light on this?
Your help is much appreciated...

yes, both of your RAM slots are full, so to get 4GB you will have to get 2 2GB sticks. Having the same model I can safely assure you that it will recognize all 4GB of the new Ram.
as for brands, there have been many I have seen recommended on this board, but one name seems to pop up consistently is Kensington, I picked up my ram from the store I bought my laptop at, so I couldn't recommend a site, sorry

Ram upgrade for 2010 15" MBP

What options do have to upgrade the RAM in a 2010 15" MBP?

Check this link at Crucial.com. They have reliable/compatible RAM upgrades. It appears you can go as high as 8GB.

RAM requirement for solaris 10

I just had an Ultra 5 given to me, and I wanted to install Solaris 10 on it. But now it seems 128 MB of ram isn't enough for the install?? With the cost of sun ram, its hardly even worth trying to upgrade it. Does anyone know if there is a way to get it installed? Is there any kind of off the shelf ram compatible with it?

I have it on a few servers with less than 200 MB RAM,
and it works really well.
One thing to keep in mind though is that its a quite
bad idea to try and run Java Desktop or Gnome when
you only have 128 MB of RAM, you should try and
download a small/flexible window manager such as
fvwm2 instead. Thats what i do on my laptop (which
has 192 MB RAM).
.7/M.What about CDE with 256 MB RAM?
OpenSUSE 10.2 runs GNOME responsively with 256 MB RAM?
I have another issue with the install - it doesn't even start up on my 256 MB system.
I'll try the nowin option and see what it does.
I let it run all night and it didn't start up.
Bad karma when you're replacing a working Linux installation.

RAM upgrade for a Satellite A100-847

I would like to upgrade the RAM for my A100-847 from my current 512 MB by adding another module for 512 MB but i face a compatibility problem because looking at the manual the only compatible modules are the following:
256 MB: PA3389U-1M25
512 MB: PA3412U-1M51
1 GB: PA3411U-1M1G
I tried looking for a module with these codes but I didn't find any in Romania. I could find a module from another manufacturer with the same specification but I don't know if these would function properly .
So I need some advice .
Thanks,
Bobby

Hi,
which manufacturer you have seen? If they have the same specs, then they should fit. The best decision would be to take some kingston or crucial modules. They were tested to work well with toshibas, so just consider buying some kingstons with the specs of the original toshiba modules and have fun with them.
In case of some further question just ask.
Greetings

RAM Upgrade for Late 2009 Mac Mini -- anyone tried 16gb?

Just a stupid question.. I've got a Mac Mini server (late 2009) that came with 4Gb of RAM.. The machine has never been speedy by any means and after finally getting some time to look into why, I think I know mostly why.. I've got the machine setup handling DNS, email (with Amavis, spam handling,etc), both MySQL and Postgres databases, Apache+WebDAV+iCAL and of course handling 2-3 user accounts being logged in at all times (using iTunes, Safari, etc). if I pull up Activity Monitor or use the "MemoryStick" utility, I see that my RAM usage is typically (almost always) at about 96% used with 7 swap files running.. I've never seen it below about 95% used. I know that this machine is capable of being outfitted with 8Gb of RAM (although Apple does not necessarily endorse that config). So, this leads to my next question -- has anyone taken some 8Gb RAM modules such as these : http://eshop.macsales.com/item/Other%20World%20Computing/1333DDR3S32S/ and tried plopping two of them in to see if they're recognized as 8Gb modules and used or not? I also have a brand-new 15" MBP (2011 model) that seems to occasionally suffer from the same fate -- it's also got 4GB of RAM and last night for quite a while it was at the 90% utilization level for RAM as well while importing some videos in iMovie '11..
I'll have to admit that I'm wondering whether 8Gb is going to be enough RAM for my purposes on the mini.. I suspect I'm probably asking it to do too much -- all of this used to be done on an older model HP Proliant server (quad CPU, hot-swap drives, redundant power supplies,etc) -- but it cost about $40+ per month in power alone..
Anyone?

Thx.. I've actually upgraded to a new 2011 Mac Mini which can still take those same 8Gb ram sticks.. Interestingly enough the new Mac Mini server still comes with a measly 4gb of RAM which just doesn't cut it with OSX Lion -- I'm constantly at 1% free RAM when I've got Mail.app running.. Ugg.. Hopefully once I put 12Gb or 16Gb in, it'll hum along..

RAM Upgrade for G$ Powerbook 1.67GHz

I have a 1.67 GHz Powerbook G4 with 512 Mb RAM I want to replace the two 256MB boards with two 1Gb boards. I think the specs for the or=iginal boasrds are PC2700 DDR SDRAM - can I safely replace these with faster boards - i.e. PC 3200 DDR SDRAM ? Any help greatly appreciated

I hate to pose a second question within a topic but it is related to the g4 1.67 powerbook. Mine is a double layer drive version (best way to differentiate, I suppose), using the pc-4200 sticks. I just upgraded and was curious about a notation within System Profiler. It had 512 to start with, in the lower slot (20, I think it's called). I bought a 1 gig stick, which was quite reasonably priced at put it in. I doubted that buying two gig would give appreciably more performance than 1.5. I installed the 1 gig in the top (meaning closest to the hatch) and ran up the machine. Recognized everything fine, says 1.5 gig in the "about...". When I looked at system profiler, it also showed 1.5; clicking on the memory detail showed 20 and 23 filled with 512 in 20 (original) and 1gig in 23. But, it shows "reversed" in the comment field. I wondered if there was any effect for installing them this way or if I should take both out and put the 1 gig in the bottom slot.
Re: the original question. I'm no powerbook expert but any computer design I know of is limited to the clock speed used on the memory board. The board clock usually is just a derivative (divided) from the main system clock and moves memory one word at a time (to a particular chip set) regardless of chip speed as long as it is the equivalent of the clock or higher. Slower chips will be erratic and cause errors as they slip words by not keeping up with the clock but that's not what was asked. Visualize memory as a bunch of firm spaghetti on a board 64 or 128 strands wide; you take a knife and cut across the ends and slide them to the edge of the board (falling is irrelevant). Then get another cut. That's how input to the memory is moved. More sophisticated designs can use more complex schemes but this is the basic.
