Upgrading Memory

[Woodwood]

Is your Mother's PC this one ? What HP call "Specifications" are here and related pages:

http://h10010.www1.hp.com/wwpc/us/en/sm/WF06a/12454-64287-89301-321881-f9-321883.html?dnr=1

Look in BIOS or download and use CPUID or Sandra or similar to find out what type of memory is already there.

Go to Crucial, Kingston or Corsair sites and use their "configurator" programs  to establish what kind of memory you need, then shop around.  I think that the maximum memory you can have is 2 x 1GB for the above PC (d325 microtower) (matched pair for dual channel).

Even with 2GB installed you may not notice any speed improvement, it depends on what you are trying to do and where the speed restriction in your system is.

Hi, I just today received a pavilion P6-2220t

It comes with 4gb RAM, and I want to upgrade it to 8.

I don't want to discard the 4gb that came in it, but I can't find the exact memory. I do have some memory that might work but it's a different brand and somewhat different speed.

I popped it open and checked, and the single DIMM in it says:

Hynix Korea 05

4gb 2Rx8 PC3 - 12800U - 11 - 11 - B1

HMT 351U6CFR8C - PB N0 AA   1222

The extra 4gb memory chip I have is:

Kingston ValueRAM 4GB 1333MHz DDR3 Non-ECC CL9 DIMM 

Would it screw things up to stick it into the second socket, or just slow down the one that's in there a bit?  I've read the specs on HP's site, as well as a lot of other stuff, but I can't tell.  I'd appreciate someone letting me know.

thanks.

You do have a 64 bit O/S ? If you have only a 32 bit O/S you will not use moe more then 4Gbyte of RAM anyway.

Kingston value RAM may not work in your PC even if it is nominally the same spec.  It is designed to be used in build-your-own PCs (I think) and as such Kingston have not designed it specifically for your PC nor have they tested it.  Having said that it might work, even though your two DIMMs are not the same speed.  The RAM will usually only function at the speed of the slowest..

Your PC probably has dual channel architecture (I have not looked up the specs) and unless you use specially paired DIMMs, which you are not,  you will lose that advantage even if your KVR works in your PC with the Hynix RAM

Another thing to watch out for is the operating voltages of the RAM; ensure they both operate at the same voltage.

The only way to confirm whether your KVR will work in your PC is to try it, I believe. I would try the KVR own irts own first, if it doesn't work by itself, then it's not going to work with the Hynix.  Only after that try them both together.  Do you have a program to test that everything's working if you don't obviousy fail ?  Memtest, speccy, HWMonitor, CPUID, etc ?

The worst that can happen is that you destroy your PC

I have now looked at the specs.  You should have a 64 bit O/S.  The memory that was supplied, Hynix PC-12800 is overspecified for your system it seems - you must have a core i3 processor I think - but that's the memory HP give you.  It says 'runs at PC3-1066 with SandyBridge processors, PC3-8500 with Pentium processors (which are are also made with SandtyBridge process ???).  It seems that your memory is running at 1333 MHz (data rate) anyway..  You must check the operating voltages of your memory.

Data for the Kingston KVR should be able to be found at http://www.kingston.com/us/memory/search/MemoryType/Default.aspx?MemoryType=ValueRam It works at 1.5V.  I don't know about the Hynix.  If can find motherboard specs it might give you more information.  I found some Hynix memory - http://www.superbiiz.com/detail.php?p=D3-4G1600H&c=nextag&hash=3047ZOGEYUeserLgz7DtN2f0Ot%2BwU%2FzRl...

It is 1.5V

I was directed from http://www.nextag.com/hynix-hmt-4gb-ddr3-pc3-12800/products-html

Let us know what you decide and the outcome.

Good luck !

Hi kealolo,

Download and use CPU-Z to determine the exact specifications for the existing dimms.  Match up the type, voltage, speed and CAS timings and you should be good to go.  If you buy directly from Kingston, then Kingston will stand behind the memory.  Check with sales and/or technical support to be sure that you are buying the correct dimms.

recently i bought HP Omni 220 1010D and i want to upgrade the RAM.

but when i see in here, HP Omni 220-1010d Desktop PC Product Specifications.

says that the memory is a 200pin DDR3, the problem is i cannot find that kind type of memory.

so which is right?! 200pin DDR3?! or 204pin DDR3?!

can i use this type of memory from Kingston DDR3?!

any help would be appreciate.

[Woodwood]

I quote from the Wikipedia article on "DDR3"

"DDR3 DIMMs have 240 pins and are electrically incompatible with DDR2. The two are prevented from being accidentally interchanged by different key notch positions on the DIMMs.[6] DDR3 SO-DIMMs have 204 pins"

You could use the memory configurator on the Kingston, Corsair or Crucial websites to find out what you need.  The Crucial website link to memory from you PC here link

The Kingston memeory finder should give equally good results for your model. (In fact I have tried the Kingston website and the Corsair website and I was unable to fnd your exact model in the list of specific PC's that that they make memory for..  You could try getting in touch with those manufacturers if you wanted to be certain).

I have looked at the page on the HP website you linked to, and indeed it does say "200-pin SO-DIMMs"  I m confused by this because 200-pin SO-DIMMs are for DDR2 memory in laptops /notebooks.  I can only think that you have made some error in the model number of the PC, or that in Indonesia (which is where HP website tells me this model is sold), everything is different !  However in the section on motherboard specs on that page it does say that there 2 DDR2 slots, which would probably be 200-pin.  The Crucial website will tell you that compatibe memory for this model is 204-pin DDR3 SO-DIMM type. - The Crucial customer support webchat advisor said (a fe minutes age) " It appears that HP possibly has a typo issue. We have your system tested to work with the DDR3 204-pin SODIMM " 

If you still aren't sure, contact HP - your system is still in guarantee I think.

The most likely culprit for this loss of speed is the memory . The good news is upgrading to more memory is a simple enough fix, and we're just the ones to walk you through the steps.Crucial memory comes with a lifetime guarantee and ships free. And they take the uncertainty out of knowing which RAM is right for your computer with their handy RAM advisor.

I have an HP S5710f desktop pc. I want to upgrade my RAm

from 3gb to 8 gb and have the appropriate new chips for it.
I removed the metal sleeve to see the motherboard and can

see where the RAM chips are located, but I can't remove the

chips because another device is above them. I think this

device is The CD drive and i can't figure out how to remove

it to get to the RAM chips.

[bob111146]

I upgraded the memory on my HP Pavilion s5710f desktop. It originally

came with a total of 3 GB, consisting of one Elpida chip with specs 1GB

1Rx8 PC3 10600U-9-10-AO and one Hynix chip with specs 2GB 2Rx8 PC3

10600U-9-10-BO. I was surprised that the chips were not of the same

brand and equal GB. I also can't tell the MHZ from the spec codes.

I replaced the original chips with two 8GB Crucial chips which have a

1333 MHZ. I chose the specific chips recommended by Crucial for my pc by

allowing Crucial to do a remote scan of my computer. Can you tell me if

my original chips were 1333 MHZ and why they were of different brands

and capacities?

[bob111146]

Sorry Woodwood, I thinki you already answered the question about having two different capacity chips being that the motherboard supports dual channel drives. The brand difference is still a question. Also I want to correct myself that i replaced the original chips with two 4GB for a total of 8GB, not two 8GB. My question about the MHZ of my original chips is basically to correctly describe them if I sell them.
