Double Checking Some Concerns

[brigantis]

Hey guys, recently I saw a deal on some cheap memory and bought them: http://www.newegg.com/Product/Product.aspx?SID=u1613056t3627495f9fp0dd0c0s701&AID=10440897&PID=1225267&Item=N82E16820231428&cm_mmc=AFC-C8Junction-_-cables-_-na-_-na&nm_mc=AFC-C8Junction
My current memory is: http://www.newegg.com/Product/Product.aspx?Item=N82E16820231303
My current Mobo is: http://www.newegg.com/Product/Product.aspx?Item=N82E16813131621
My current processor is: http://www.newegg.com/Product/Product.aspx?Item=N82E16819115215
Running Win 7 64-bit

I have a couple of questions regarding upgrading the memory:

1. If I were to just add them into the remaining 2 channels and keep my current RAM in there, dual channel would still be active right?

2. If I were to add them into the remaining 2 channels, would I have to manually change anything in the BIOS? I noticed everything is the same except for the timing: 7-8-7-24-2N on the old, and 9-9-9-24 on the new.

3. Assuming I would have to underclock the new memory some amount, would I get better performance if I just took the old sticks out and used only the new ones?

Basically I'm curious as to what option would result in the best performance.

Thanks guys!

The link you sent is deactivated. But it's always best to match ALL the sticks of memory (size, speed, latency, etc.) when you populate all slots. Much less chance of issues, that way.

Oops heres a new link: http://www.newegg.com/Product/Product.aspx?SID=u1613056t3627495f9fp0dd0c0s701&AID=10440897&PID=1225267&Item=N82E16820231428&cm_mmc=AFC-C8Junction-_-cables-_-na-_-na&nm_mc=AFC-C8Junction

But is it worth trying to see what happens when I put in the new RAm with the old one? They are very similar.

Well, the timings are different, the voltages are different... I don't see how you feel they are similar. Personally, I wouldn't spend my money on that test.

What's a good program to measure RAM performance to figure out the best setup?
