How to find Ram module model to buy with complete details like pin count and clock speeed and freque

[HanuK]

Not able to find the RAM Module spec that fits my computer.  Looking at HP spare parts, does not list RAM modules.

any suggestions on how to find this info to purchase the RAM module?

HP Envy 15 t [Mode  WOO62AV]

Thank you.

Hi:

I would see if running the free Crucial memory scan tool will give you that information.

[HanuK]

that didn't help, it did came back with message

"Crucial currently does not have any compatible upgrades available for your particular system."

I can't find the model number based on the product info you posted.

The closest I could come up with is WOQ62AV, which is a 15-as000 model.

Here is the link to the service manual for that model series.

The memory upgrade info can be found in chapter 1 on page 2.

Also, I have zipped up and attached below, a free utility you can run, that will tell you everything you ever wanted to know about the memory specs.

though I haven't found this number on my computer, I could get the following info from my purchase order, it shows label mentioned below. can I get the Ram model spec / user guide for this specific item.

HP ENVY - 15t-as100 CTO

[Paul_Tikkanen]

Yes, I have posted the link to the service manual for that model series above.

it covers the model series 15-as000-099 and 15-as100-199.

Hi

The reason can be that, like mine, there is no current manufacturer of my memory module.

You are therefore dependant on there being stock on someone's shelves.

[HanuK]

yes, running thorugh the same issue in finding memory module part. when I look at user guide shared, it shows DDR4-2133. But the part is not available in HP. looking at Crucial ram upgrades for same model, it lists 2666 or 2400 SODIMMS.  if I add one of these, will it work with other HP RAM module [probably 2133], that came with original laptop without any issues??  or Am I supposed to replace both modules for the compatibility reasons. 

Crucial 8GB DDR4-2666 SODIMM

Crucial 8GB DDR4-2400 SODIMM

Hi:

Run that utility I attached earlier.

I bet the memory module in your notebook is either 2666 or 2400.

In any event, the 2400 module should downclock to 2133 if there is a PC4-2133 memory module in there now.
