Original RAMs in HP notebooks

What DDR2 RAM manufacturer is HP using in their notebooks? Is it some big company like Kingston or similar or do they have their own brand?

 

No its not gonna be a major brand. Only hardcore customizers and high end machines will have the option for a name brand at an extra cost. HPs and most other low end machines will have simpletech or random ram, as there is no HP/Dell/Acer ram.

 

And, to tell you the truth...it doesn't really matter 8)

 

is there a tool where you can identify which brand of RAM is installed on your machine?

thnx

 

Yes, CPU-Z will tell you what brand of memory you're using as well as clock speed and timings.

I'm asking because I want to upgrade RAM in my just ordered nc8430. I would like to buy the same brand as is originally installed by HP to avoid any compatibility problems (I have problems with returning the RAM in my country).

 

A simple way to check would be to take it out and look. My dv8000t came with a stick of Samsung and I think the other stick was Micron. My configuration ordered was 2 x 256MB for a total of 512 MB. I upgraded to a 1GB stick of OCZ and it works perfectly fine without a problem.

 

I was thinking the same, but I was worried that HP could somehow mask the original producer, i.e. put some additional label with the HP logo or anything similar. So the RAM modules are not modified, labeled or anything else by HP? They just buy the modules and plug there?

 

U dont have to buy the same ram as it originally came with. As long as the specs are the same (pins, speed, voltage etc...) there is no difference in what brand u get in terms of compatability, they all work.

 

HP use several brands. I have seen them use Micron(Crucial), Samsung, Hynix, Nanya & Infineon. There might be few other brands but I believe these are the most popular ones they use.

The best way to know what RAM you will have is to just wait for the computer to arrive and then buy the RAM.

 

Well, this means that really most RAM modules should work with HP and I don't need to worry. I have read several threads about HP's being sensitive on RAM and that they don't work with every module.

 

Yeah, I have paired memories from brands from different manufacturers before(my old R3000 had Crucial + stock Infineon memory), never has there been any issues. Issues mgiht arise only if the memory is bad or if uses low quality components. There are some no name sticks which are available for cheap, but it is better to avoid these and as long as you buy good quality RAM, using it with another brand should not create any problems.

 

Samsung, Nanya have been the 2 brands found in the dv8000t series. I upgrade mine to OCZ without any issues.

 

My dv2000t came with Samsung memory.

 

Heres a question...

PC Wizard (made by the same people as cpu-z) has the following entry for my ram in my 6000z

Manufacturer : Nanya Technology
Part Number : NT512T64UH8A1FN-3C
Serial Number : 179C1474
Type : DDR2-SDRAM PC2-5300 (333 MHz)
Format : SO-DIMM (67.6 x 3)
Size : 512 MB (0 rows, 2 banks)


My question is why is it showing up as 333 MHz instead of 667? Is it just a detection error in pc wizard or maybe something else? I want to keep an eye on memory prices so i can eventually go up to 2gig and I just want to make sure im looking at the correct ram

 

667MHz memory runs at 333MHz, since it is capable of double data rate transfer. 333MHz is your real clock speed and the 667MHz is your effective speed.

 

wow, now i just feel really dumb... thats something i should have remembered...

 

The nc8430 is quite picky with memory. If you are going for dual channel get EXACTLY the same memory to avoid conflicts. Tested 6 different combinations of same speed memory until I found one that worked flawlessly. ALWAYS test your system with utilities made for that purpose. Just booting and running casual everyday applications is not enough. So try for example super pi 32M (takes about 20 minutes to complete) before labeling your system stable with your new memory.

 

There is a memory test in BIOS, isn't it enough?

 

Mine came with sticks of Hyundai Electronics and I know for a fact that they don't play nice with RAM made by PNY.

 

Be careful when you choose 667 RAM with Z. One of review shows the actual speed will be vary from 600 to 637. This is not AMD problem but BIOS from different manufactors.

533 seems OK for TL-50 to TL-60, but works at 513 on TL-56 if I remember it correct. TL-60 runs 667 at 600. DDR2 400 perfectly matches every X2. I wander if 65nm X2 will perfectly match 800 since that's the only integer multiplex for FID with higher clock.
