RAM Upgrade to be done.

Hi,
We are going to upgrade RAM in our SAP server.
Current RAM size is 16GB and proposed RAM would be 24GB.
We have Oracle 10.2 as our Database and Windows 2003 server as OS.
Please guide the procedure and what are the different parameters to be set/change at SAP level.
Also, what all changed would require at DB level.
Rgds;

> Please explain what bottlenecks are? It's simple, we want to upgrade RAM from 16GB to 24GB.
> Please guide on this and don't ask who has proposed this please )
Well... I'm not asking who did this but why
There must be a reason why you want to add more memory, right? Otherwise you woudln't do it. And exactly that reason would be necessary to know, what need to be reconfigured
If you have swapping on the operating system because of huge amounts of data in the workprocess you would increase PHYS_MEMSIZE. If you database is "slow" because the SGA is too small you reconfigure the database (only). You can also do a combination of both - but to know which one make sense it's necesary to know, where there is a problem or what you want to do with the memory.

HP Envy 13 1030nr. Windows 7 64-bit. RAM upgrade help.

I just purchased a RAM upgrade for my Envy 13 and I was trying to figure out how exactly to access the memory module. I couldn't find a youtube video for the Envy 13 and reading the maintenance manual provides only partial instructions to access the memory module. It tells you what you need to do (Disconnect the TouchPad cable 2 from the low insertion force (LIF) connector on the system board) but not how to do it without damaging the computer. I don't want to permanently sever a cable or anything so I'm looking for help via a link to a video or more detailed instructions on exactly how to safely access the memory module.
I was under the impression that this would be a quick replacement, but the more I read the manual, the more I think that this is going to be a little more complicated than opening up the bottom and removing the current RAM chip and replacing it with the one I have. Any help would be appreciated. Thanks!

Here is the Manual:

Memory is indeed on the motherboard and getting there requires nearly complete disassembly. See Page 4-26. Not sure how this qualifies as "easy" and if you have not done this before you should get some help. And yes, keep careful track of those screws.

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.

Kernel Power error after Win 7 and RAM upgrade

Hello,
I posted earlier on the subject of win7 and ram upgrades. I did both and it seemed to go fine. I did the ram first ... replaced a 667Mhz 1gb with a 800Mhz 2gb. A couple of days later the computer just shut itself down and restarted. Since then it has done it another 5 times, seemingly at random. Yesterday I decided to spend some time looking into it and found the 'event log'. All the shutdowns are recorded as 'critical'. A search on the web/here showed other occurences of the fault associated with drivers as much as anything.
After I did the win update I did update almost every driver with ones from this site.
Other than the shutdowns the only issues I have which are of very mild concern are the length of time the fingerprint reader takes to be present and that occasionally the cursor is unavailable for about a minute after logging on. When you try and control it it jumps about anywhere but where you want it to go. I rolled back the alps driver and that seems to have sorted the cursor issue.
So, details of the shutdown from the event log are as follows.

There's more (I've shown it all below) but it's not that important. When I looked into it I found details of the problem on the microsoft knowledge base. Its described here http://support.microsoft.com/kb/2028504.
I believe I fit into scenario 3 for cause and resolution.
So, it seems that win7 and mixed speed ram may be a problem on some computers ... probably only a tiny number, but it looks like the HP3507 is one of them. I did see somewhere that I could down speed from 667 to 266 which might help with memory compatability but I can't see anywhere on the the insydeH20 bios where to do it. BIOS is version F18 .... upgraded from F15 as part of the Win7/RAM ugrade.
Before I swap back to the 'old' memory I'll see if anybody here can come up with any ideas. It may be that I have to sell off the expensive 2gb memory (ddr2 800mhz 200 pin) for £39.99 from maplin at a bargain price and get 2gb of 667Mhz from somewhere.
The full 'detail' regarding the fault is below.
Bye for now.

Hi DWeiland and Schwede,
Thanks for your replies. Yes I did the runtime engine registry change and also mass compiled the LV7.1 folder and my sourcecode. I still see the problem as I have set the LV adapter as Lv 7.1.1 runtime engine. Now I have changed it to LV7.1 development system. With this setting, it is not giving any error. Thus I don’t see any problem now. The older version of the code had the adapter as the runtime engine for some reason, now I have changed the setting to the development system. I hope that it shouldn’t be a problem.
Thanks again!
Thank you,
Sasi

Mac pro 5,1 RAM Upgrade

I am planning to give my Mac Pro (Mid 2010) another RAM upgrade. As the official Kingston/Crucial DIMMs do not include 16GB DIMMs, I think of choosing Kingston Value RAM: ECC Registered (3x, 16GB, DDR3-1600, DIMM 240). Has anyone here in the forum tried these?
Thanks for your comments.

The biggest official Kingston part is KTA-MP1333/8g which is a single 8GB module.
For 16GB modules the main criteria are that
It must be registered memory - not buffered, this is more because there aren't any 16GB buffered DIMMS
You cannot mix registered and buffered so any other existing memory left fitted must also be registered, as it happens you are supposed to not mix 16GB with smaller sizes anyway
It should be 1333Mhz DDR3 although in theory 1066Mhz DDR3 would work, again I don't believe there are any 16GB 1066Mhz DIMMS
It should be ECC (error correcting)
CL9
The presence of a Thermal Sensor is apparently not compulsory, i.e. memory without it will work in a Mac Pro.
I have not used any 16GB DIMMS myself but other than OWC as per the link provided by Illaass, the following might be suitable
KVR13R9D4K4/64i - this is a kit of 4 x 16GB and this article has a post from someone who says they worked for them http://forums.macrumors.com/showthread.php?t=1493588
If you can find a kit of 2 x 16GB of the same type then logically they should also work, they would probably be KVR13R9D4K2/32i. As a reminder to do 64GB or more you need dual processors. The single processor model Mac Pro 2010 is limited to 48GB.
See http://www.kingston.com/datasheets/KVR13R9D4K2_32I.pdf

HP Mini 110-3150CA - RAM Upgrade?

I just picked up a HP Mini 110-3150CA - I have 1gb Ram - But I would like to upgrade to 2GB ram -- can this be done? And what type of Ram do I buy?

Here is the Manual.
Manual
Instructions for upgrading memory are on page 51.
It uses DDR2 laptop memory 667 mhz which is commonly available even at a store like Best Buy. It only has one module so you have to replace the 1 gig module in it with a 2 gig module. You will be glad you did. It will run much better on 2 gigs.

Do I need a RAM upgrade

Hi- I've got a PB 1.67GHZ (aluminum) with 1GB RAM (2 512MB chips).
I tend to leave lots of apps open (around 10) for my workflow. I'm always having to jump between apps. None of them are particularly taxing though I do play one game that takes over the system (so I shut down other apps for that). My system definitely gets slower with lots of apps open.
Currently, my Activity Monitor shows page in/out as 307943/213848. I'm thinking that second number is not good and I ought to get some more RAM.
In addition to recommending a RAM upgrade, should I go for just an upgrade to 1.5GB or go for 2GB?

Currently, my Activity Monitor shows page in/out as
307943/213848. I'm thinking that second number is
not good and I ought to get some more RAM.
Your system is memory deprived. The general guideline is that page outs should be 10% or less of page ins. Yours are currently about 69%, meaning for every 10 page ins, your system is paging out roughly 7 pages. A page out is where the system has to move something out of memory to disk to make room for something else, and that impacts performance.
You can upgrade to 1.5gb by installing a 1gb RAM strip, and monitor your page ins/outs and performance/feel. For what you run, that may do it for you. However, if you don't see much improvement, then going to 2gb is available to you.
Recommend Crucial, Kingston (not their valueram line), or Samsung memory, which has proven reliable in our PB's. Crucial can be found at their website http://www.crucial.com , Kingston at http://www.kingston.com , and Samsung is available from a number of companies, of which OWC at http://www.macsales.com is one source.

Intel Rapid Start stops working when RAM upgraded

I have a brand new ENVY dv7-7212nr notebook running Windows 8 64-bit.
This machine has Intel Rapid Storage Technology which caches hard disk data (I think on the 32GB SSD) and Intel Rapid Start Technology which stores active memory in the SSD cache (I think) when the computer enters a hibernation state.
The first thing I did was upgrade the RAM from 8GB to 16GB. It works fine, but then I get an error message "your system does not appear to have intel rapid start technology enabled."
HP provides very little information on this, basically none. I assume the memory is being cached on the SSD, but I don't know how to verify this. Also I notice that acceleration is not enabled under the Rapid Storage Tecnology applet for either drive.
I called tech support twice but the techs knew nothing about upgrading RAM beyond the usual and couldn't get it to work either.
Does anybody even know exactly how the SSD is being used in my system? That would be valuable information to me.
Thanks in advance!
This question was solved.
View Solution.

Thanks for reading my reply.
The "little SSD" is still a drive and not a chip, although you are right that it is little and it is attached to the motherboard. It is little because its form factor is not the typical 2.5 inch size but what's call "mSATA". In fact, the service manual for this dv7-7212nr laptop shows you how you can remove and replace or upgrade this mSATA SSD:
Below is a comparison of how small the mSATA form factor is to other drive sizes (from Left to Right: mSATA, 1.8", 2.5", 3.5"):
So if I want to replace the mSATA 32 GB SSD with a 64 GB SSD, I would have to get a mSATA SSD, not the typical 2.5" ones. So for this dv7-7212nr laptop, there can be 3 total drives installed: one in the mSATA slot and two in the 2.5'' drive bays. However, the default configuration as sold by HP only has one mSATA 32 GB SSD and one 750 GB SATA hard drive, with the remaining drive bay empty.
This dv7-7212nr laptop does contain all the latest (and perhaps more complex) technologies and HP probably does not expect the typical user/consumer to go and muck around all the default settings. However, if one is curious and willing to make the effort to learn, the material is just a google search away.
Here are the instructions for setting up Intel Rapid STORAGE Technology (aka Intel Smart Response Technology): http://download.intel.com/support/chipsets/sb/intel_smart_response_technology_user_guide.pdf
For this dv7-7212nr laptop, you can ignore steps 1-4 because the BIOS is already configured properly from the factory (unless some changes were made by the end user).
Here are the instructions for setting up Intel Rapid Start Technology:
http://download.intel.com/support/motherboards/desktop/sb/rapid_start_technology_user_guide_v11.pdf
For this particular laptop, ignore steps 1-7 but it is important to do this first: set up Intel Smart Response Technology as above, making sure to allow enough space on the SSD for a hibernation partition that is equal to or greater than the total size of RAM installed. Then follow steps 8 to the end of the guide. It is important to set up Intel Smart Response before Intel Rapid Start because Intel Smart Response will destroy all partitions and data on the disk (if you set up a hibernation partition for Intel Rapid Start first, it will be removed when you set up Intel Smart Response).
I have successfully ENable and DISable these technologies on my laptop using the above guides (with my modifications). WARNING: back up all data before trying any of this.
In your case, I agree that you can also disable Rapid START and just use the whole SSD for acceleration along with the 16 GB RAM upgrade.

Battery drains while sleeping after RAM upgrade

Installed 16 GB of RAM and a Hybrid/SSD 1 TB internal HD on MacBook Pro 15" mid 2012 and now the battery drains while the computer is in sleep mode, about 1-3 % per hour. Before the RAM upgrade (stock 4 GB of RAM) there was no noticeable battery drain, so I assume it has to do with the upgrade. I read that it takes more power to maintain 16 GB of RAM during sleep, so my questions are as follows:
Is 1-3% per hour normal?
Will resetting the SMC help the issue?
Does the Hybrid HD have anything to do with this?
I am not too happy about the battery drain as it happens that I don't use my laptop for some time and prior to the upgrade the loss of battery charge was not an issue at all. Is this the price I have to pay for maxing out my RAM or is there a way (resets, settings, etc) to reduce the amount of battery loss
Thanks for your input.

Hi everybody. I have the same question. I have a macbook unibody late 2008. I have recently upgraded the OS to Yosemite. In order to have a smoother functioning of the system I have immediately replaced my original 2Gb (1+1) RAM with 8 Gb (4+4). Since then, I have noticed a dramatic reduction of my battery charge during sleep mode. Now after 8 hours of sleep it goes from 100% to around 65% (before it was 95%). Is it a natural consequence of having installed a larger RAM or there could be anything wrong with my settings?
I have read a couple of articles about standby mode and standbydelay setting but this does not apply to my model of macbook.
Here is my pmset -g result:

Mac Pro (Late 2013) - 64GB RAM Upgrade

Anyone have any recomendations on third party brand for a 64GB RAM upgrade.
Apple RAM costs approx £1000 GBP whereas Crucial is approx £645 GBP, OWC is similar to crucial if I import from the US but I'm not sure if their ram are Registered or unbuffered.
The above is all cost based - should i be considering other factors such as performance and reliability?
Also when moving to Registered DIMMs i understand that the presence of the Registered DIMM controller on the DIMMs consumes one clock cycle is this a significant hit in performace over Unbuffered DIMMs?

Grant Bennet-Alder wrote:

I don't think so. Take a look at these DIMMs for reference (this Vendor show the specs of exactly what modules will be shipped to you). Even the 16GB DIMMs, while Registered, are still showing they perform at CL9 level (9 clocks to access) -- the same as unbuffered.
http://www.datamemorysystems.com/apple-mac-pro-6-core-intel-xeon-e5-3-5ghz-me253 ll/a-cto-late-2013-memory-upgrades/
Just thought i would update you. I spoke to DMS Technical Support and apparently that DMS CL9 Rating is a typo. It should be CL13!

Issues with sleep/wake feature after 16GB RAM upgrade in my MacBook Pro. Any thoughts?

Just installed a 16GB RAM upgrade in my MacBook Pro and now it doesn't wake up on it's own when I open the lid. I have to press the power button. It works fine with a smaller RAM upgrade.
I've tried putting in just one of the 8GB modules and the sleep/wake feature works as normal so there isn't a problem with the RAM modules that I've bought (Crucial.com). I've also put in a combination of Apple's original RAM and the new ones to make 10GB (8GB + 2GB), and the sleep/wake feature works on that too. Put both 8GB modules back in and the MacBook doesn't wake up when I open the lid, I have to press the power button to wake it up. The MacBook itself works fine, super fast and the memory is recognised on 'About This Mac', the sleep/wake issue is the only problem I'm having with the 16GB RAM.
Any thoughts on this? Has anybody else had this sleep/wake issue like this when upgrading RAM?

I upgraded my early 2011 MBP to 16 gigs with Crucial. My machine would not sleep properly, because when I tried to wake it, it would wake from its hibernate image file. This is the issue I've seen here in this list.
I tried all the suggestions I saw on these groups. Nothing helped. I contacted Crucial, who suggested that if their RAM was defective, they'd replace it per their warranty process. I needed some proof it was their RAM causing the problem.
I put the original 8 gigs RAM back in the machine (2 4 gig sticks), and it behaved normally. I then put one stick of Crucial RAM in, all by itself. The machine behaved normally. I put the other stick of Crucial RAM back in, and took the first one out. The machine would not properly sleep and wake from sleep. This proved that one stick was causing the problem, and the other was not.
Defective RAM!
I then requested and received an RMA from Crucial to send the defective RAM back. They paid shipping. I got new sticks of RAM about a week later. These new sticks of RAM work properly. No sleep issues.
I'm surprised and disappointed to say that this is not the first time I've received defective RAM from Crucial. I've purchased from them for years, and had GREAT service and received high quality products. The past couple years my experience has been different.
I'm still pretty steamed about this, as I spent a great deal of time trying to diagnose the problem and fix it. I don't really have that kind of time to waste. My expectation was that their RAM was high quality, and unlikely to be at fault.
Perhaps this is just a bad batch of RAM. I get that. I can forgive them once. But this has happened twice in the past three years. I'll look elsewhere for my next memory purchase.
Keep in mind that their customer ratings are generally very high. My experience is probably isolated.

The culture is changing with the ability to upgrade the newer machines. I've noticed a lot of people on this forum more closed to the idea of upgrading, most are unaware it can even be done, which is sad in my opinion. Maybe because this is the official support forum. But the other mac sites are like what I'm used to in the past working with pcs:

etresoft, we know that mac computers are the best...period. Hardware upgrades are also better for some of the same reasons that make apple computers better; not as customizable -- only certain upgrade paths are possible. Upgrade process more difficult because of mac's intricate design. But once you do the upgrade right, it just works beautifully. And you extend the life of you machine another two years at less than half the cost of getting a new mac.
Open you mind brother. Apple has done everything right, this is just another part of their strategy and I think it's great.

MacBook Pro won't boot after ram upgrade...

Hey everybody! Hope everyone is having a great Christmas! I got a 16gb ram upgrade for my 2012 MacBook Pro 15 today and I am having some trouble with the upgrade. Its an odd problem. I installed the two 8gb sticks no problem, but when I try and boot into OS X the machine shows the apple logo with the spinning wheel underneath, and then it just shuts itself off. I don't know what the problem is. The machine boots fine into my Windows 7 partition, and registers both sticks of ram. OS X restore also boots no problem and lets me reinstall OS X, which is what I am doing currently. IDK if this is just because of a hardare change or what. The ram I installed is Adata pc3 12800 1600mhz ram, so it should be supported.

Replace the Ram, buy from OWC or Crucial, buy the Ram Apple recommend, don't rely on "it should work"

RAM Upgrade to be done.
