Windows 7: Mixing RAM

I have 4GB of DDR3 Ram right now, and I'm thinking of adding another 4GB. I have this ram right now, but it is deactivated on the Newegg site.

Because I can't buy that ram anymore, can I mix it with this? Because, as far as I can tell, they are basically identical.



Thanks

My advice is dont; nothing but problems. I have seen many cases where it looked ok on paper but it was still a problem

Hmm, unless you set the timings manually on both set of RAMs, it should be OK. they're the same Manufacturer, and the same model, only different Cas Latencies

I'd recommend to set them at 9-9-9-24 on both sets.

Although it looks like the set you already have works at 1.65V, and the new will be working at 1.35V, somebody please correct me if i'm wrong, BUT! if you undervolt your current RAM to 1.35V and set the timings to 9-9-9-24 in the BIOS of course, would be totally compatible with the new set the OP wants to buy?

Punkster may very well be right but I never recommend mixing and matching RAM. Your system will automatically (if they'll run together) default to the lower set.

It's my opinion in order to get the full benefit of more ram to always use the exact model and manufacture numbered Ram.
Fabe

No no, i totally understand, i wouln't mix RAMs either, but since they are the same manufacturer, the same model (just different latencies) i thought it might be a viable solution for the OP given the fact that the RAMs he already have are Out of Stock and probably won't be in stock again

But totally agree with you, mixing RAMs, not my thing..

I guess the OP will have to find another retailer selling the RAMs or buy another set of RAMs:

You could buy 2 of these: Newegg.com - G.SKILL Ripjaws X Series 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model F3-12800CL9D-4GBXL

Or one of these: Newegg.com - G.SKILL Ripjaws X Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model F3-12800CL9D-8GBXL

Same thing but one's a 4GB kit (2 x 2GB) and the other one is an 8GB kit (2 x 4GB)

Another thing OP, OCZ stopped manufacturing RAM memory...

Here: OCZ Stops Making DRAM, Focuses on SSDs

Can you find the same RAM you've got anywhere else?

Found them, Beau. But at 111.04$.. i don't think that's a deal

Amazon.com: OCZ Technology 2x2 GB DDR3 PC3-12800 Platinum Series CL6 Edition Low Voltage 4 GB Memory OCZ3P1600C6LV4GK: Electronics

With that money i'd buy a 2 x 4GB RAM from another manufacturer: IE, the one i suggested above and that's it, the OP would still have 2 slots extras, if he buys these ones, he'll use all the slots

Of course if the latencies are important for the OP, then i could find the CL7 from the same manufacturer, but they're a little more expensive that the ones i posted (CL9).

And that would still be a better deal than buying that set from Amazon

Sounds like it would be a good plan Punkster.

This. Just because Newegg is out, doesn't mean no one else has them. Check plenty of other places, and be safe by matching the memory.

This. i found them (check above posts) but at 112$ i don't think that's a deal. the OP is better off buying another set of RAMs which is cheaper and he could even buy an 8GB Kit (2 x 4GB) and he'll still have 2 available slots for another 8GB Kit making it 16GB RAM (totally overkill for an average-user, but you get my point )
