DDR3-12800 8 GB RAM modules for X201-X220-X230 notebooks?

Crucial's info recommends the 1600 mhz memory for all 3 models. Technically, speed gets reduced to 8500 for the X201. Is that ccorrect? Hope they will keep the Thinkpad series alive. A rugged, fast small and lightweight business notebook is a wonderful tool. I wouldn't trade my old X201 for any I-Pad (need a keyboard and the Thinkpads' are great). To upgrade my notebooks, there would be considerable cost savings by just buying the 8 GB modules @ 12,800 instead of @ 8500 for the X201. Hope that will work? Cheers,Chris

The X201 supports only 2x 4GB, so no 8GB Modules for her... My X201's are very picky with 12800 RAM, I normally use 10600 RAM for this generation, altough some forum members reported sucesfull experiences with this type of RAM.
The X220/X230 have no problem with 8GB modules or 12800 RAM but avoid the cheaper RAM lines like the "Value RAM" from Kingston or the "Value Select" from Corsair, and no-name brands as well.

RAM Upgrade for HP 15-D103TX Notebook Laptop

Hi All,
I will really appriciate if you could help me out in this.
I am looking to upgrade the RAM of my laptop, ie. the HP 15-D103TX. I currently have the stock RAM.
What I want to know is -
1. Will this RAM work on my laptop - http://www.flipkart.com/corsair-vengeance-ddr3-4-gb-1-x-gb-pc-ram-cmz4gx3m1a1600c9/p/itmd2rypbx4eeha...
2. Will my HP Warrenty cover the replacement of the RAM?
Looking forward to the reply on this at the earliest as I need to take an urgent decision.
Thanks!

Hi,
Not much information about your machine, don't know why:
http://h10025.www1.hp.com/ewfrf/wc/manualCategory?cc=us&lc=en&product=6875924
But on many HP 15" laptops now, you can't upgrade RAM yourself. New design won't allow you to do that. You have to talk with "Authorized Service Provider parts".

How can I upgrade RAM memory for Pavilion dv6-3267cl notebook PC?

My laptop is HP Pavilion dv6-3267cl Entertainment Notebook PC
and OS is Windows 7 Home Premium 64-bit Service Pack 1.
It has intel core i5 cpu m480 2.67ghz 2667mhz 2 core 4 logical processor and two of 2GB SODIMM Samsung 1067MHz are used right now. (total 4GB memory) I'd like to upgrade the memory and
What is the maximum GB of RAM this laptop can have?
Which type of RAM cards should I install? (brand/MHz/GB...)
I tried a 8GB PC3 10600 1333MHz CL9 SoDimm and it caused an error and won't start Windows so I went back to original 2GB.

Hi:
The maximum memory you can run in a pc with the i5 first generation core processor is 2 x 4 GB.

Ram Modules

An excellent ram module for the 865PE motherboards is the PC3500 level 1 modules. They allow for more headroom concerning overclocking and are designed to run at 2-3-3-6 which is the suggestion for this chipset anyway. Why pay more money for the very low latency when it seems to cause many problems with the 865PE and 875 Intel chipsets. Even the Corsair senior moderators recommend the PC3500 over the PC3200LL. I am presently using Mushkin PC3500 level 1 and it seems to work very well and is quite stable. I am very impressed with the MSI motherboards it seems to be the Intel chipsets that are wound a little to tight.

I think that Rastakirk's point is that the 875 chipset works better with more relaxed timings. Corsair even had to reprogram their low latency modules(ras to cas at 3 instead of 2)to function with this chipset. PeteJ61 methodology is correct for his system set-up-but I still wonder. Obviously until the 875 low latency at the fsb level for a non overclocker is the way to go. Congrats to Pet3J61 for being able to achieve this. Yet there are way too many inconsistencies with users concerning the low latency modules. It unfortunately seems more hit or miss as to what will work with what. Bios versions, matched sets of ram modules, maunufactures of the autual chips on the ram, perhaps even the specific board you actually receive are all "X" factors. Never have I seen this type of problem before and it certainly has both the motherboard(in the form of bios updates)and ram makers scrambling. The 875/865 has brought a new level to tweaking and finding compatible peripherals.

1GB RAM stick for Power Mac G4 MDD Okay?

My Power Mac 1.25 GHz dual-boot G4 currently has 768 MB of DDR SDRAM. One slot has a 256 MB DDR SDRAM PC2600U-25330, a second slot has a 512 MB DDR SDRAM PC2600U-25330 stick, and two slots are empty. The MDD will recognize up to 2GB of RAM.
I have a really good deal on a Apple G5 Power Mac G4 MDD 1GB DDR PC3200 RAM Memory stick. The seller says it will work in a G5 and also my G4. Is a 1GB stick safe to buy or should I try to find two 512s instead? I don't have "matching pairs" now and wonder how critical that is?

Other World Computing only has 256MB & 512MB RAM modules for the G4 MDD. http://eshop.macsales.com/MyOWC/Upgrades.cfm?model=175 I would think that if 1GB modules would work, they would sell them. Give OWC a call & ask.
The G5 RAM is PC3200 & may or may not be compatible with your G4. Even if it is, it will only operate at your Mac's processor speed & not 3200. The G5 Macs require matched pairs, but the G4 does not.
 Cheers, Tom

DDR3 RAM specification for MSI Z77A-GD65

Hello MSIers ,
I am about to buy the MSI Z77A-GD65 or GD55 not sure yet ... I used Gigabyte boards for 10 years and they always state to use 1.5 volt RAM sticks ...
Now for MSI and the mention board , what voltage should I pick ? I want 2 sticks of 4GB DDR3 1600MHz and might look to faster frequencies like 2333 MHz ??? will it work with an I7 3770 right out the box (if I load XMP in BIOS) ? can lower latencies or CAS as well ?
Thanks

http://www.mushkin.com/Memory/Redline.aspx
Allot of the mushkin comes pre-under-timed (the xmp profile does anway) As that computer is an AMD platform, I need to match the xmp profile and adjust the fsb/ dram ratio to get the correct speed & timings. Both of those listed computers are quite stable.
The corsair memory I have listed has an xmp profile of 11-11-11-30, I manually under-timed that when I was tweaking. That is the lowest I could go and maintain stability.
One thing to keep in mind when you look at memory, is that almost all that you see out there is 1333 memory which has been tested and tuned (Overclocked) to w/er limit. Even ddr3-1600 you buy will by default run at 1333 as the 1600 is an XMP profile extension to the SPD. So no matter what you buy over 1333, you are most likely going to need to at minimum enable the xmp profile or at worst tinker with the speed & timings manually.
Nice .. Thank you ..
So what DDR3 freq. / timings you suggest for the best performance and stil very stable (as long as I (most likely) need to tinker a bit around the BIOS and XMP) ? I am gonna use the I7 3770 locked version CPU
You advice or against , maybe 2000 freq or more DDR3 with the Z77AGD65 ? or you advice with choosing a lower latency modules but at 1600 MHz freq like this http://www.mushkin.com/Memory/Redline/997056.aspx ?

Satellite Pro C50-A-1E4 runs unstable using new RAM modules

I have the above machine and have upgraded the RAM (to 8GB) a long while ago. I normally upgrade BIOS if there is a new release.
However, for some while my machine has been unstable and this is due to machine running RAM at XMP1866 (933MHz) instead of CPU rated 1600 (800MHz). I have attached screengrab from Piriform Speccy to report this.
There is no setting within UEFI BIOS 1.40 to adjust RAM timing and therefore BIOS takes SPD data incorrectly for CPU ID.
I am unable to locate earlier BIOS to check if this pattern was repeated but it took over a year to display fault hence the machine is out of warranty. If I put smaller sticks of 1600 RAM the system seems stable.
However, I purchased the RAM to make use of it. I am now unable to test if the RAM is faulty as it will not pass Memtest (either lockup or crash out) but I am unsure as to whether system instability is cause of system being OC due to BIOS or faulty RAM.
The question being it ran perfectly for about a year before displaying errors. BIOS should correctly detect speed setting from JEDEC standard data in EEPROM. It does not do this. I have often ran 'overspec' memory in other PCs without encountering this behaviour. It is only troubleshooting that has made me aware of this discrepancy.
RAM is Crucial Ballistix 8GB-1866 BLS8G3N18AES4CEU.16FE

As far as I know in case of RAM upgrade Toshiba recommends the usage of these modules.
4GB DDR3-1600 PA5037U-1M4G
8GB DDR3-1600 PA5037U-1M8G
The specifications are:
Memory Speed: 1600Mhz PC3-12800
Capacity: 8GB
Pins: 204 SODIMM
RAM Type: DDR3 SODIMM
Rank: Dual Rank
CAS Latency (CL): CL11
Voltage: 1.5v
I would recommend you to use modules which meet exactly the same specifications.
That's sidestepping the point nicely. I still believe the BIOS to not be reading the EEPROMs correctly, but hey if you can swerve that one then I'll swerve Toshiba in future.
Thanks for editing the post title.

Can I install an 8Gb Ram Module on a 2010 Imac?

Acording to apple support iMac (Mid 2010): Memory specifications - Apple Support, "You can use RAM module sizes of 2 GB or 4 GB in each slot", but clearly is more cost efficient to be able to install an 8Gb and a 4Gb, as the iMac already comes with two 2Gb modules, the iMac only takes 4 cards and it has a max RAM memory capacity of 16Gb.
Can I install a 8Gb?
Thank you!

Why doesn't the new ram memory for iMac (mid 2011) work (different brand)?

Hello,
I have an Macbook pro at home (early 2011) and an iMac (mid 2011).
My macbook pro had 2 x 2GB ram and I wanted it to be higher, zo I bought 2 x 4GB ram from Kingston. I installed it succesfully in the macbook pro.
I saw that the ram in my macbook and iMac where the same type (1333MHz DDR3), so I figured the Ram-modules were interchangable. The iMac has 2 x 4GB ram put in by Apple itself. It's a weird brand name, something Asian that I hadn't heard off.
I thought I could put the original ones from my macbook pro (brand Samsung) in with the original ones that where already in the iMac.
So the slots would look like:
4GB 4GB -> already in iMac, original modules with brand name I can't remember ;-).
2GB 2GB -> original modules from macbook pro Samsung
I also put in in like shown: the same types next to eachother.
Then I turned my iMac on and it only "beeped".
So I tried to put it in different combinations (4GB next to 2GB etc etc). But it still "beeped".
Very frustrating... because I thought I was doing a good thing by buying Kingston (quite expensive also...).
Now I think I had better purchased new 2 x 4GB Samsung and combined that with the 2 x 2GB Samsung from the macbook and put it all in the iMac. And take those of the iMac (2 x 4GB Asian brand) and put those in the macbook... This way it were all the same brands combined...
But I did by Kingston... so... why can't I combine the original iMac ram modules with the Samung modules from the macbook????? I've read that in older iMac models, the slots are sensitive for different brands, but couldn't find out for sure for my iMac (mid 2011). It's a bit stupid, no... Both mac's are from 2011 and have the same specifications...
Could anyone give me an answer?
A little bit mad at Mac right now ;-).
Thanks in advance!
Wallking.
PS: if it is about the OSX I'm using... can't update to Maverick for software licence reasons... I need the iMac for work a lot...

Hello,
I'm sorry if it wasn't clear... but I don't have ram issues with the Kingston type...
I used the new Kinsgtons in my macbook and wanted to take the originals from the macbook (Samsung) and them put in my iMac next to the other modules that were already in the iMac.
I know it's a bit confusing... ;-)
So... I have 2 x 4gb in my iMac from a brand I can't remember the name off... And I also wanted to put in 2 x 2 GB Samsung modules. So that would count up to 12 GB ram. Why? Because I took the Samsung modules out of my macbook and I thought I could reuse them in my iMac since they have the same specifications (1333MHz DDR3). But My iMac won't start up as soon as I insert those 2 Samsung modules.

Is there a maximum RAM capacity for a Macbook Pro 13 inch Mid 2009?

My questions is essentially, is there a maximum RAM capacity for a Macbook Pro 13 inch Mid 2009? I'm aware there are two RAM slots in my machine, but in past experiences with other laptops/desktop computers (not Apple) there was a default maximum which couldn't be overidden despite how much RAM was inserted.

You can upgrade up to 8GB using 2 x 4GB 204-pin PC3-8500 (1066 MHz) DDR3 modules. That's the maximum (unlike 2011 and later models which Apple tells you can only hold 8GB but can actually run 16GB).
If you do order RAM, order from a Mac memory specialist - Crucial, OWC, Corsair, etc.
Good luck,
Clinton

8540p dual core i7 620m 8gb ram module?

Can my Elitebook 8540p with i7 620m processor handle 2x8gb ram modules? Yes there are only the 2 slots as this is the dual core not the quad core. All literature I have read suggests it is only compatible with 4GB modules. But others have found the 8540w model spec sheet says the same thing but the specs we're written before 8gb modules we're available. And the 8gb modules worked in their systems. Is this the case with the 8540p as well? Also I have found that others have used 8gb modules in the dual core i5 models. I do realize I will need to upgrade from 32 bit Win7 to 64bit if the ram is compatible. Any insight is appreciated.

The motherboard chipset used on the first generation Intel Core processors such as the i7-620m (P55m) maxxes at 4 per slot, I thought. We started seeing 16 gig compatibility in 2 slots (8 per slot) with the 2d gen processors. However, the Manual is cryptic: Four customer-accessible/upgradeable memory module slots supporting up to 16 GB of RAM in models that use quad-core processors Two customer-accessible/upgradeable memory module slots supporting up to 8 GB of RAM in models that use dual-core processors Supports dual-channel memory PC3-10600, 1333-MHz, DDR3 Supports the following configurations: ● 32768 (8192 × 4) ● 16684 (8192 × 2) manual Seems to be talking out of both sides of its mouth but I am pretty sure you cannot install 2 x 8 in there and have it work. If you prove me wrong (I hope you do) please report back for the good of the Forum.

Mixing RAM Modules (1gig + 2gig = 3gig)

Hello,
I am about to buy a Mac Mini and I am on a tight budget. The one thing I want to do for sure is upgrade the memory, but I'm in a quandary of sorts given my budget. The retailer where I want to buy the Mini from only sells the appropriate RAM for the Mini in 2gig modules. So here's my question: I know it is possible to mix the stock 1gig stick with a 2gig stick to get 3 gig of RAM total, but will it be worth it to me? I realize that the best configuration would be to slap in 2 2gig modules in and just be done with it, but with 3gig, would I be appreciatively shooting myself in the foot and killing the machine's performance, or wouldn't I notice? I need to have the memory installed at purchase because I am physically handicapped and adding the memory myself is out of the question. And after researching how to replace memory on the Mini, I wouldn't have the courage to ask anybody I know to attempt to do it after buying it. Is mixing RAM modules a good idea?
Thanks in advance.
Malcolm

Nope, I am not confused, There does have generation between Mac mini model. Maybe not official, but we all know. Check About This Mac ---> More Info ---> Model Identifier : Macmini2,1 (That means, 2nd generation)
Macmini 3,x (means 3rd generation I supposed)
And the 3rd generation doesn't support Dual Channel, referred to Crucial.com

Memory modules for Msi Big Bang trinergy

Hey forum,
i want to buy some memory modules for my trinergy mobo because the ones i had earlier also proved to be incompatible. I would like to ask you if there are any memory modules besides the ones recommended from the MSI site concerning my mobo. I am looking for a 2x2 gb ram kit with a heat dispenser so it can work around 1600mHz. Thank you in advance
P.S Is the list on the site the only one? i mean are there any updated versions of it with more high end memory modules tested?

Ideally you would provide us with your fullsystem specs first >>Posting Guide<<
From a memory perspective, the reason these modules have heatspreaders is mostly due to marketing and to impress the potential buyers. The secondary reason is that most manufacturers sell you overvolted and overclocked 1066 or 1333 chips on a 1600 marketed module that needs 1,65V instead of the standard 1,5V. Your memory controller is part of the CPU and natively only supports 1333 at 1,5V.
If you really insist, then at least get yourself a 1600 kit that does this speed at 1,5V. One of the modules that seem to work well are the CMZ4GX3M2A1600C9 from Corsair. From a user perspective, the mem modules from Crucial that you see in my signature come highly recommended as they have been proven to work on the P55 platform whenever used.

Mixing RAM modules on a 800Mhz machine

I have a new Mac Pro. 800Mhz. I want to install more memory but n find any 800Mhz 2Gb modules for sale as yet.
I have the option of installing 667mhz modules.
Will this cause a problem mixing 800Mhz and 667Mhz modules?

You posted your question in the wrong forum. This forum is for pre-G3 Macs. You should repost in the Power Mac G5 forums @ http://discussions.apple.com/category.jspa?categoryID=108
That said, this will probably answr your question.
You can't use a processor speed lower (667Mhz) than that specified (800Mhz). Plus there are other restrictions. See *How do you upgrade the RAM in the Mac Pro? How much RAM of what type does it support?*
@ http://www.everymac.com/systems/apple/mac_pro/faq/mac-pro-how-to-upgrade-memory- what-type-ram.html
You can buy the 800Mhz RAM at Other World Computing @ http://eshop.macsales.com/Search/Search.cfm?Ne=5000&Ntt=MacPro+800MHz+MatchedPair&Ntk=Primary&Ns=P_Popularity%7C1&N=7318
