RAM upgrade problem for HP DV5 1102TU Laptop

June 6, 2020 at 01:29:13
Specs: Windows 7, RAM upgrade
Why symmtronics RAM does not work on HP laptop?
I have HP DV5 1102TU Laptop purchased in 2009. Presently it has 3GB RAM. Since, system is very slow for Windows 7, I want to upgrade it to 6GB by replacing 1GB with symmetronics DDR2 800MHz. But after installation system doesn't boot. I replaced, symmtronics 4GB RAM with new symmetronics 4GB assuming that, 1st time procured RAM might have problem. After installing 2nd time also, system is not booting. I don't know, what to do. Kindly help.
Thanks in advance.

According to these, 4GB is the system's limit:(apparently only 2GB max per slot according to the manual)

Sir,
Thanks for the quick reply.
But, specification says 4gb per slot....
Kindly clarify.

"But, specification says 4gb per slot...."

Based the info on the assumption in the 2nd link:

"Memory replacement/upgrade is on page 60. 4 gigs is th emax. It will use DDR2-667 or DDR2-800 memory. The latter is a bit more widely available."

According to page 60 of the manual (also in 2nd link):

Memory module
Description Spare part number
For use only with computer models equipped with AMD processors (667-MHz, PC2-5300, 1-DIMM):
2048-MB 484268-002
1024-MB 484267-002

For use only with computer models equipped with Intel processors (667-MHz, PC2-5300, 1-DIMM):
2048-MB 484268-001
1024-MB 484267-001
512-MB 484266-001

If you have a different model, then see what the manual for it states. Could have been upgraded to a different BIOS version or something that allows a greater capacity per slot (personally do not own that laptop)...

The HP manual may say 2x2GB, but various memory sites say 2x4GB.

I never heard of "symmetronics" before. I googled it & it was corrected to "Simmtronics", apparently from India? I have no idea if it's any good or not.

Did you confirm the RAM specs, speed, voltage, CAS, non-ECC? Did you try one 4GB stick by itself to see if it would work? Why after 10+ years is the laptop too slow? If it was OK before, the problem is probably too much crapware installed, not too little RAM. Are you running Win7 32-bit or 64-bit? If it's 32-bit version, there's no point installing more than 4GB total because the 32-bit OS can't use any more than that.

My suggestion would be to make copies of all your important data, then wipe the HDD & install Win10. It's still free & you can use your HP Win7 product key to activate it.

Or install Linux instead.

The manual refers to a single memory module. The only time
it refers to plural moduleS is when it describes memory
modules in general, as having a notch. It never says or implies
that more than one module can be installed. So if you installed
two modules, either the manual is wrong, or you have a different
computer model.

This is about the tenth time I've edited this post...

The text always refers to a single module, and the diagram
shows only a single module in the compartment, but there
appears to be room for a second module in the compartment.
I don't see any sign of connectors for a second module.

"The manual refers to a single memory module"

Did you look at the manual? from page 11 of 173:

Supports up to 4096 MB system memory
●4096-MB total system memory (2048 MB × 2, dual-channel)
●3072-MB total system memory (2048 MB × 1 + 1024 × 1)
●2048-MB total system memory (1024 MB × 2, dual-channel)
●2048-MB total system memory (2048 MB × 1)
●1024-MB total system memory (512 MB × 2, dual-channel)
●1024-MB total system memory (1024 MB × 1)

Regardless, the manual was printed in August 2008, it's possible 4GB sticks weren't mainstream at the time it was published. This model laptop is based on the Intel PM45 chipset which supports 8GB RAM so my guess is the wrong type RAM was purchased. Possibly the wrong density or ranking.

I looked at the manual that was linked from the page that T-R-A
linked in the first reply (2nd link). It is titled "HP Pavilion dv5
Entertainment PC Maintenance and Service Guide". It shows
that the computer is a notebook/laptop. It has only 164 pages,
so we are looking at different manuals. Page 11 of this one is
about the keys on the keyboard.

Page 3 says the same as what you quoted. Notice that what you
quoted doesn't say anything about "modules". But I don't know
what the definition of a module is. I presume it is a single pluggable
board. On pages 60-61 the manual refers to "the memory module"
and "a memory module". The only place it mentions "modules" is
when it says "Note: Memory modules are designed with a notch (3)
to prevent incorrect insertion into the memory module slot." The (3)
refers to a notation on the diagram pointing out the notch.

That diagram shows that the space into which the memory module
fits is twice the size of the module, so I won't be surprised if a second
module will fit in it, but the text dosn't say so.

The diagrams appear to be computer graphics, not photos, so I'm a
bit unsure how accurate the scale and perspective are when the
memory module is shown lifted up slightly out of the compartment.
What could be a second memory module is shown below, behind
and beyond the first one, in the installed position. It looks too far
down in the compartment compared to the first one. It is sort of like
the Escher drawing of staircases going in impossible directions.
I can't tell if that is supposed to be a memory module or an empty
space where a second module could go.

I looked here: http://h10032.www1.hp.com/ctg/Manua...
Opened with Firefox, upper left says "i (1 of 173)". Change the "i" to a "3" & press enter, it will say "3 (11 of 173)"

A memory module is commonly referred to as a "memory stick" or "stick of memory". Have you ever added or upgraded memory sticks in a laptop before? Sometimes they're side by side in the same compartment; sometimes they're stacked in the same compartment; & other times they're in two completely different places such as one in a compartment & a second beneath the keyboard.
