Would my motherboard support a 8GB memory 1866Mhz? Like the CORSAIR VENGEANCE 8GB DDR3 1866MHZ.

It would work with it, but the memory would be downclocked. You wouldn't get better performance using ultra-fast memory.

You may be able to do a bios update if there is one available for your laptop and get more out of that ram but its a long shot! i know my laptop only officially supported the crappy Celeron 2.2 Single core that it came with but i decided to try it with a T8500 2.0 Dual core and it works! both cores run perfect!

My point is that a lot of motherboards have specs that are tested but that may not be their limit. Am i saying that its a great idea to push these limits necessarily, no, and on my case, i must be very careful that the heat from the 65nm C2D does not push past what the heatsink for the 45nm S-core celeron can dissipate.

Oh and like eire said, a sata 2 port maxed out is still an insanely fast thing! my lappy boots crazy fast

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.

So it will be clocked down to about 1033Mhz?

So how much will it clock down to?

Just bought 2x4GB memory to my laptop and it seems like it doesnt work either. So i did some research and it seems like my laptops limit is pc3 8500 memory. Would 16GB pc3 8500 memory work then?

PM45 Chipset and Penryn Socket 478 Q9000/9100/9200 CPU limits you to 8 gigs. Let me find some memory options for you.

Just to be thorough, what is the make and model of the memory you purchased? It should be something like...
G.Skill F3-10600CL9D-8GBSQ
Crucial CT2KIT51264BC1067
Kingston KVR1333D3SOK2/8GR

If you cannot make out a model number of any kind, just type everything you see on it.

The BIOS of the X18-1390eo will not allow you to adjust the CPU settings. This tells us that you will be sticking with PC3 8500 memory SO-DIMMS.

You can purchase any sets of 8GB (2 x 4GB) 204-Pin DDR3 1066 (PC3 8500) SO-DIMMs.
Crucial and Kingston SO-DIMMs should be the most compatible.

X-Mas 2012 (most of it):
Coolermaster CM Storm || SeaSonic SS-660XP || ASUS P8Z77-V PREMIUM || Intel Core i7-3770K || 16 Gigabytes Corsair-Veng. || eVGA GTX 560ti || Audigy 2 ZS Platinum || 240GB Intel 520/ 2TB Samsung HDD || Liteon Blu-ray || Logitech G700 || Microsoft SIDEWINDER X4 || 20.1" NEC WMGX^2 || Onkyo TX-SR702 Receiver (with Bowers & Wilkins Speakers) || Sennheiser HD600 Headphones

I tought my cpu limit is a Intel 2 Quad Extreme Qx9300, because somone mentioned in a forum that they had hp hdx18 laptop with that cpu. And here is my ram memory info , link below

That is the memory that came with the system. What is the information on the memory you purchased?
The X18-1930 can accommodate most Socket P(478)Penryn processors, but that doesn't change your memory limit. The maximum is 8gigs.

Windows Vista 64-bit?

START button
right click COMPUTER
select PROPERTIES

This should show you how much ram the system is utilizing, what OS you are using and your Windows score.

You can also get there by:
Control Panel>System and Security>System

If you have it in Classic View:
Control Panel>System

Alternatively:
WINDOWS key + R (or just type in your START menu search box):

msinfo32

System Information should pop up... "System Type" will either be x86(32 bit) or x64(64 bit)

I don't think HP would sell you a system with more than 4gigs without offering a 64bit solution, but I thought I'd check. A 32 bit system can only utilize up to 3.2gigs of memory, so putting more in a 32-bit system would be silly.

I also have to agree with a former post that increasing your memory won't really offer any noticeable increases in performance. The best upgrade you could make for your computer is to slap an SSD inside of it.

I have twin 1366 gaming rigs each with(3x4GB) of Corsair Dominator memory. The motherboards can use 6 dimms. In the name of fun, I put all the memory in one system to test how things ran(Basically I opened up everything in my start menu, no crash). More memory allows you to load up more items on your computer. In gaming terms, it doesn't necessarily make a game run faster or load faster when there is a sufficient amount present.

BTW: If you still want to purchase some more memory, you may want to purchase PC3 10666 as it appears to be cheaper than the PC3 8500, but I cannot confirm that the modules will work in your system.

Educational Videos to clarify:


Increasing memory CAN increase performance, but not if you already have enough. If you have enough memory to hold your entire program for immediate access, you will get no benefits from a further increase in memory.




In Conclusion:

You have plenty of memory. You will not notice anything from increasing your memory. Getting an SSD will significantly shorten load times, but it will not improve your FPS in games.

Let me see ill try answering all of your questions :D

1: I use Windows 7 64bit version.
2: my system is utillizing all of the 6gb that i have in the laptop.
3: Score:

Processor: 7.0
Memory : 7.0
Graphics : 5.5
Gaming : 6.5
Hardisk : 7.6

4: Yes i tried the 2x4 GB sticks with PC3 10666 (CORSAIR 8GB DDR3 1333MHZ (2X4GB) SO-DIMM) and even 16GB kit of the same brand. so i did a little research and found out my pc ony can handle PC3 8500. and the price isnt that diffrent.

5: Thank you for the videos but i do know about memory, i do multitask alot that why i need more memory.

Another question before i order 8500 memory sticks. Do PC3 8500 come in two diffrent speeds or does my pc not utillize all of the speed? like the pc3 8500 533mhz and the 1066mhz.

And thank you for taking the time.

No. 533Mhz is the actual operating frequency of your DDR3 1066 (PC3 8500) memory.
533x2=1066 which is your Speed.

Is it necessary to get 2x 4GB? or can i just buy a random 1x 4GB 8500 stick? because i already have a 1 4GB stick in the system.

it's best to get a matching pair of ram modules. if they are not matched, it can be the difference between the "single channel" and "dual channel"

You can get one. Make sure it is 1.5v with timing of 7-7-7-20.
http://www.newegg.com/Product/Product.aspx?Item=N82E16820148289

Edit: Almost all the PC3 8500s are 7-7-7-20, so you shouldn't have any issues with timing. The only thing that might happen is you end up with a bad stick that needs RMA'd. This seems to happen to me a lot, but I've never had a problem sending off for a new set.

So the memory won't be effected by how the other memory works?

No. They won't be affected.

Like Mordeux said, almost ALL PC3 8500 memory has the same timings, so they all pretty much work the same way, meaning that 2 sticks that are different brands will mostly be the same so it is fine to buy 1 stick and put it with some other random 1 stick of memory. As long as they are the same memory size, like 4 GB with another 4 GB.

I bought this ram memory here: http://www.ebay.com/itm/Corsair-Value-Select-4GB-SO-DIMM-DDR3-PC3-8500-CL7-CM3X4GSD1066-/290905444675?pt=DE_Technik_Computerzubeh%C3%B6r_Arbeitsspeicher&hash=item43bb50d143

still did not work and it was a pc 8500 memory and a 4gb. I Put it alone in my laptop and it did not start, the screen was black but then i put it on the other slot of my laptop it did start but when im am at the windows logo it blue screens and restarts. i tried with my old 4gb memory and the new one still nothing just black screen and i tried to switch their places and still nothing ?
