Installed New Ram, Wireless Issues Occurring Non Stop

[ipbyrne]

Hello,

I run an iMac mid 2010. Here is the pic of it's info.



I recently installed 2 4g RAM cards into it to boost my ram to 12g.
Here is the product I used:

Since installing these cards, I have had a ton of issues with my wireless. At night, it will just randomly drop-off on my iMac, and the wireless network won't even show up agian unless I restart the computer. The internet speed has also been terribly slow during times and while all this is going on, my MacBook Air has no issues with the internet. below is a speed comparison.

Has anyone experience similar issues or know of any possible solutions/what could be causing this issue?

Thanks in advanced!

Remove the RAM you added and re-test against the same scenario. If nothing changes, the issue is something else. If problem goes away, you got bad RAM and will need to RMA it.

Wrong memory modules according to Mactracker.

Mid 2010 iMac 27" core i5 or core i7

They say your iMac takes:

Maximum Memory 32 GB (Core i5 or Core i7 Actual) 16 GB (Apple)
Memory Slots 4 - 204-pin PC3-10600 (1333 MHz) DDR3 SO-DIMM

I wonder if the original modules are those by Apple or were they also replaced?

Wrong memory is always the biggest danger to upgrading yourself. Do not buy from Amazon as they are not specific enough in their description. If these are OWC modules, contact OWC live chat and explain your problem and how you erred in not buying the modules from them and ask kindly if they would be prepared to replace them with the correct modules as OWC has a lifetime guarantee on their memory modules.

Charlie is correct. That memory is for the iMac before yours, the late 2009. I upgraded a couple of them and that was the RAM for the late 2009 for sure. Yours needs faster 1333Mhz RAM. Always go directly to OWC and not through Amazon as OWC will show you your model and show you the RAM for that model.

To me though even though the RAM is incorrect it would more likely cause the iMac to lock up. Why it's affecting just network speed and Wifi connect has me stumped.

So weird. I tested each card individually and found out it was one of the original 2g RAM cards that was causing the issue. Currently running the other original 2g chip that worked with the 2 4g chip I linked earlier and the issues have gone away.

Thanks for all the suggestions guys.
