Do both of your new modules work together with one of the new ones or when installed alone? It looks from your post as if one of them does and the other does not. Would you mind clarifying that, please?

If one of them works and the other doesn't, we will replace them for you. Please contact our Customer Support department or use the links on our RMA page to request an exchange. Be sure to use the proper link for your location, and reference this thread so they can see the troubleshooting you have done.

No, either one of the new chips will work alone!

Both the new chips will work if fitted alone.

Did you try one stick at a time in both slots? You may have a failing or failed memory slot.

to be exact bot chips will work in either slot.
