4 ram stick 2 pairs which are allmost identical, apart from voltage

[leighmorgan395]

When I brought my ram I started with 4gb, I went to buy another 4 of same ram for compatibility but they didn't make that exact one so I brought another 4gb pair and it was xactly the same from timing to part number, I'm pretty sure part number was same apart from maybe 1 number or letter, same make, same speed, only difference is one pairs rated 1.5 and the other 1.6, my question is is it best to run higher or lower, xmp favours a certain socket so it would set it to 1.5 if one pair was in black socket but if I switch other pair to black socket it sets to 1.6. confused. Having a nightmare with my pc ATM. Just want it all running good again.

RAM is sold in matched sets for a reason. There is never a guarantee mixing RAM will work. You can try setting both sticks to the speed, voltage and timings of the slowest stick and hope it works. Better would be to sell both sticks and buy a matched set. Don't use XMP though as it looks like that isn't working.

Well like I said it's not different it's almost like one pair is just a newer version or something and like I said in my post I wanted to get exact same but they wernt manufacturered , I couldn't find so had to match these up and there identical apart from the voltage, again, same timing , same speed , DIFFERNT VOLTAGE, same make. I get the feeling this pair is just the same but newer or something I don't know. It's weird. All identical apart from voltage and look .

I knew full well it's best to get all identical but I couldn't find that exact pair so matched the specs allmost perfect.

God reading my own posts, I'm so tired of trying to fix my pc I'm struggling to put together a sentence

RAM of the same product number from the same manufacturer can be so different it won't work together. Different production runs can use different ICs and the subtimings can be completely different. That's why it's sold in matched kits. Those kits are guaranteed to work together.

It's not weird Leigh, Like anort3 said: RAM is sold in matched sets for a reason.
