Dual channel help. one stick is 8gb 1.35v cl8 1600 and one stick is 8gb 1.5v cl9 1600 (almost same timings)

Ok so I have here a stick of ddr3 1.35v 8gb 1600mhz ram @ Timing 8-8-8-24, cas latency of 8 (N82E16820148655) THEN I have an ALMOST similar stick which is ddr3 1.5v 8gb 1600mhz @ 9-9-9-24, cas latency of 9 (N82E16820148540).

I had ordered the 1st stick you see there just recently on an impulse buy during a sale. The question/problem: is if I can run these in dual channel mode? They are both "Crucial" branded but they have different names, the first one is "crucial tactical" while the 2nd one is "crucial ballistix". I read everywhere that they need to be matching but to what extent?

Can I just simply overclock the first one to 1.5v and keep the mhz, timings, and latency the same while over clocking the 2nd one to the timings of 8-8-8-24 (instead of 9-9-9-24 CL9) and put the cas latency to 8 (i wont have to up the voltage though to get down to 8-8-8-24 right? ultimately... resulting in me having to increase the 1st sticks 1.35v past 1.5v and even further to match the 2nd stick? like say set them both to 1.7v?), then will it run in dual channel mode?

Can I just put the 1.35v and increase it to 1.5v and keep timings, then on 2nd stick just keep same stock 1.5v and put the 9-9-9-24 CL9 down to 8-8-8-24 CL8? then since everything is the same it should run in dual channel right? I just have 2 slots on my motherboard. I am sort of learning as I go so bear with me if it sounds noobish :(

also I want to note that I havnt received the stick that I just bought on sale yet which is the 1st stick. So I havnt tried it out yet. I just want to be sure though before going through the trouble of shipping one back to return it to get a matching stick.

  1. I'm not sure how to overclock them separately. But my guess is that they are incompatible. I'd suggest trying to sell the 1.35V for half the original price you paid and get a second 1.5v as you already have.

    Well I think I've seen an option in my bios on an matching pair of old ram that has an option to change the timings of each one differently? Though I may be wrong on that notion, and cant clock these separately? My bad human memory, i cant remember if it actually let me clock them separately. hmmmm.. and then if so would it even run dual channel? :( Though If this is not possible I think I will end up returning the 1.5v stick since I still have a week to return it. Since I think the 1.35v one is a little better. I still want to know if this is possible because I would have to pay return shipping :( and would loose a few dollars :( :(
  3. I think the 1.5V one is better. Yes the 1.35v is CAS 8 but voltage matters. I'd rather have 1.5V CAS 9. However, since you already bought a 1.35V one then I guess return the 1.5V one for a 1.35V one.

    Try then with the 8GB 1.35 in slot 1, manually set the freq to 1600, the timings to 9-9-9-27, DRAM voltage to 1.5 and give them a try
  5. thanks i will try when i get home. I will keep you all updated.

    update: looks like that ram still hasn't arrived yet from when i ordered it last week. Probably will get it tomorrow in the mail. I did read up a little bit more about it though. it looks like it is dual voltage of either 1.34 or 1.5v So it looks like i will just need to put timings to match at 9-9-9-24 CL9 and hopefully it will work in dual channel mode. *crosses fingers*

    So after finally getting the ram in the mail sure enough I ran into problems initially, So I set all of the timings the same on both sticks of ram to 9 9 9 24, voltage to 1.5 and set it to 1600 mhz and it ended up working out just great. That kicked it into dual channel and it runs beautifully. Though luckily it turns out that this stick had dual voltages and ran at 1.5v instead of 1.34. Anyhow, it worked! Thanks all.
  8. Great, Have fun!
  9. wow. great to hear. Very interesting that it worked out ok.
