Hi. i own a HP HDX18eo, at the time one could choose up till 8GB of RAM memory but instead i bought the 6gb version. Now i wanted to upgrade the laptop till 16GB ram with 2x8 GB, i have 2 slots for RAM on my laptop. i was wondering if it would work with 16GB of ram with CORSAIR 16GB DDR3 1333MHZ (2X8GB) SO-DIMM memory.

According to HP technical specifications, your mainboard can read 1Gb, 2Gb, and 4Gb memory modules, DDR2 SO-DIMM type. The 6Gb version is a 4Gb and 2Gb module combination.

DO NOT INSTALL DDR3 in your notebook. It is not compatible and will not work (DDR2 SO-DIMM is 200 pin, DDR3 SO-DIMM is 204-pin, furthermore DDR2 and DDR3 use very different sync methods and are not compatible to the same memory controller type).

Your only memory upgrade option is to remove the 2Gb module and add a 4Gb in it's place, giving 8Gb total. DDR2 is not made larger than 4Gb per SO-DIMM.

I've found that many motherboard manufacturers will not list certain sizes and brands of memory combinations as being compatible because they have not fully tested those sizes and brands. It doesn't always mean that they don't work. My experience is mainly with ASUS and MSI boards, and most of the time, I've been able to drop larger RAM sticks in, test the RAM, and fire it up and have the computer run fine.

I HAVE had a few systems that I tried it with that would not work.

What this means to me in practical terms is that if I have the memory to try it, I will give it a shot and try it out. Most of the time the gamble pays off.

My experience with NOT laptop motherboards - which are different beasts.. but I still wonder if things would work the same...

Okay, let's dial it back in.

This system is limited to DDR2. DDR2 only comes as big as 4Gb per SO-DIMM. 2 sockets, means 8Gb MAX. You CANNOT load DDR3 into a system designed for DDR2.

I get the impression that we didn't read through the responses first...

I was specifically addressing the memory size limitations of the memory that the manufacturers may show initially.

DDR2 does not come in larger varieties. There is no other option to consider.

Well now. eire. i just downloaded CPU-Z and to look at the memory type and it say's DDR3. so back to the question will it work with 16GB of ram if i get that? Look at the picture below

Okay, totally confused. Even Kingston.com and MemoryStock.com show the HDX18 as a DDR2 board, but CPU-Z tends to be fairly sharp by ID of the modules. My advice: pull out a module and count the pins. 200 is DDR2, 204 is DDR3. If you have DDR3, 16Gb should be at least a possibility.

Ill try later. And i don't think i will count the pins, because it says everything on the memory sticker.

Well its a DDR3 alright but will it somehow increase my system for Games, i mean will it increase the graphics FPS? Because im going to buy a Intel SSD for my laptop to. (550MB Read 550MB Write)

Sounds like HP must have revised the system during production and forgot to tell the rest of the world... LOL!

Well, for games, 4Gb is typically more than enough. Given that you are not using shared memory for graphics (assuming you have the specified GeForce 9600M with the dedicated 512Mb) adding memory will not necessarily give you any improvement in games, aside from giving more room for other apps and utilities that remain memory resident in the background and reducing disk swapping. I wouldn't expect miracles, though.

The SSD will improve load times, for sure, and if it is hosting the virtual memory you may be seeing a push in performance, but again it isn't directly affecting the GPU and won't make it faster.

1333 Mhz is fine but i don't think that PC supports 16gb.

It is difficult to know, given that according to every info I can find that PC never came in a DDR3 flavor, and yet we have one here! It would be nice to find some 8Gb SO-DIMMs that poviking could try without having to buy.

Would be nice Eire :D The thing is the Company i bought it from they costomized it a bit. I really did not know at the time. So i send a message to the company and they told me the limit is 8Gb but i don't belive they know that it supports DDR3 themselfs. Even the stickers that i have on the laptop side, the processor sticke ris wrong. i do have a Quad Core Processor and its says Centrino 2 inside when. I really dont know.

Well im not 100% sure if the company i bought it from did costumize it. So i did run a Geekbench and looked my motherboard ''Quanta 3610'' searched in google for that and no one i saw did have the same Laptop with the same motherboard if so they did have DDR2.

here is the file saved from GeekBench all info about my laptop is there open it with geekbench.

Got it figured out. You are based on the HDX 18T, not the HDX 18. COMPLETELY DIFFERENT MOTHERBOARD, and very few were made, towards the end of the product cycle. And, yes, the 18T used DDR3 memory. According to HP, 8Gb is still the limit, but the chipset supports 8Gb memory modules, so 16Gb is possible, assuming HP hasn't limited it in the BIOS.

Sorry about the confusion. Your mobo name research gave me a lot more info to pursue.

That's it. I just identified the motherboard as coming from an obscure lineup called "18T". But HDX 18 1390eo is the actual model name.

Problem is, the 18T specification was so short lived that everyone supplying components seems to have totally overlooked it, and route searches to series 18.

It is SATA3 compatible, but I think your bus is maxed out at SATA2. If I have right info, here.

SATA is easy, lots of backwards compatibility. A SATA2 port pushed to it's max will be wicked fast, so don't go slow on the SSD.

Hi eire1274 :D need help with somthing again. I was wondering if my graphics card Gefroce GT 130M was replaceble with a GT 650M, if so and it is possible. WHere do i buy a GT 650M for my laptop, ive been searching on many sites but with no result. Or is it only sold in quantities for companies?

Sorry to break it to you, but the mobile parts are typically embedded on the motherboard and aren't replaceable. That's the major downside of portables (notebooks / laptops): not a lot can be upgraded.

Haven't updated the status of the 16gb ram :P . Just wanted to tell you guys that 16GB 1333Mhz Ram won't work on hp hdx18 1390eo. Even tried one 8Gb stick. It is limited to 2x4GB SO DIMM DDR3 memory.

Sad! This looks like it was a generational upgrade inside HP. It got DDR3, but not the memory limits that went with it. Unfortunate, and HP tends to treat model numbers as a group, so the HDX18T didn't get an 8Gb per socket BIOS revision because the HDX18s didn't have the ability.
