RAM upgrade on Pavilion DV7 - 2230ev (product number is VL035EA#B1A) Notebook PC

[AntonisKoum]

Hi everyone, 

I own a Pavilion DV7 - 2230ev (product number is VL035EA#B1A) Notebook PC.  The motherboard is a QUANTA-3624 and the CPU: Intel Mobile Core 2 Duo P8800 @ 2.66GHz Penryn 45nm Technology. My installed RAM is 2 modules of 2 Gb (total 4 Gb RAM), the DRAM frequency is 533 MHz. After reading some topics on the web I have a question. Is it possible to upgrade RAM to 8 Gb or maybe more? And what is the max frequency of the RAM that my motherboard can support?  I forget to mention these

CAS# Latency (CL) 7 clocks
RAS# to CAS# Delay (tRCD) 7 clocks
RAS# Precharge (tRP) 7 clocks
Cycle Time (tRAS) 20 clocks

Thank you very much,

Antonis.

The DV7-2000 series can have either DDR2 or DDR3 memory and the best info I could find says your model has DDR3 which is good for you as it is cheaper. Yes your max is 2 x 4 = 8 gig DDR3-SO-DIMM. You are seeing it as 533 mhz because the memory is DDR = double data rate so it actually cycles at 533 mhz but the system "fetches" data twice on every cycle so it is commonly known as DDR3-1066. 1066 is as fast as you can install. DDR3-1333 will work but it will just run at 1066 speed.

Post back with any more questions and please accept as solution if this is the info you needed.

So, as I can understand, the maximum RAM that I can install is 8Gb right? Or I can install 16Gb (2 modules of 8Gb at the frequency of 1066MHz each)?

Thanks again

8 gigs (2 x 4) is the maximum
