Is my RAM fake?

I bought some off eBay from a seller Hong Kong. they had like 90,000+ transactions and something like 99.7% feedback (checked the negative ones and it was things like "slow delivery, did not turn up, etc.."

Anyway, I received mine a week later. I matched it to the exact same model code using CPU-Z but the one I got has 4 little black things on each side, whereas when opening my laptop it has 8 on one side

I've installed it anyway... working so far and CPU-Z confirms they both have the same model number, manufacturer, bandwidth, timings, etc..

One is from 2011 (the one that came with the laptop) and the one I just got is a couple months old, so is it possible they just changed it?

 

Yes probably higher density chips used. So less of them needed in total.

In other words, not fake.

 

lol... paranoid a little?

Do you have double the RAM? Did you run a RAMTEST overnight (or at least a few hours)?

Do your memory intensive programs work stable with the added RAM capacity?

Those are the important questions to ask, I think?

 

Thanks guys

I only just got it this morning so will run memtest tonight on it

 

RAM is made with tight margins and in such vast quantities, not to mention with state subsidies in many cases, that fake RAM is pretty rare and I'm not sure it would be worth the effort of making it, unless it was generic RAM disguised as brand name high performance RAM.

 

I ran SIW on my laptop, and the model code is showing up as m471b5773d m0-ck0 (which doesn't come up on google) instead of m471b5773d h0-ck0

Also, both show as PC12800 but it's running at 665MHz in CPU-Z

It should be 800 right (PC12800 = 1600)? is it just that the mobo/cpu (i3-2350M) don't support it at the full 1600MHz?

Thanks

 

Yep. Sorry.

 

Ughh, wonder why they put PC12800 RAM in the laptop in the first place

Thanks anyway
