Stuck between a few DDR3 choices, pls help

post #1 of 6
Thread Starter 
I'm ordering my first build within a week, but I'm stuck with a few questions about memory. Please help me out. I'll add links to choices.

I have read good things about the Cosair Vengeance memory. I feel like getting 8GB (2*4GB). They are also 1.5v which the Sandy Bridge prefers I believe. Or at least states as standard.

1. Is there a difference between the coloured versions? or is the regular, the red and the blue version all the same?

Regular: http://www.alternate.nl/html/product...3&l3=DDR3-1600

Blue: http://www.alternate.nl/html/product...3&l3=DDR3-1600

Red: http://www.alternate.nl/html/product...3&l3=DDR3-1600

2. If I'm correct the CL8 timing would be faster than the CL9. Does it really make any difference to pay a bit more for the CL8 version? I mean real world difference. Would someone notice it when doing anything on the PC?

Cosair Vengeance CL8 version at 5 euros more: http://www.alternate.nl/html/product...3&l3=DDR3-1600

3. There is a G.Skill Sniper Low Voltage series that runs at 1.25v. Does this have any positive side to it? Run cooler or something like that. They're about 13 euros more expensive than the regular Cosair Vengeance and 8 more than the CL8 version.

G.Skill 8 GB 1.25v sniper set: http://www.alternate.nl/html/product...3&l3=DDR3-1600

Thanks a lot for your help, much appreciated.

All of them have the same timings & voltages. So the answer to your question is they are ALL the same.

CL stands for CAS latency. It's the delay time(in clock cycles) between when a memory controller tells the RAM to access data in a particular section of the RAM and when the data is actually sent. There is a slight speed increase with lower latency, but lower latency also helps with "smoothness".

If you can grab CL8 for not much more, then it's definitely worth it. However, if you have to spend a lot of money that you really don't want to, then it's not. It's also not greatly noticeable in real-world performance.

There's many upsides to lower voltages on RAM, however, the "big" thing is the headroom for overclocking. For example, getting from 1600Mhz to 2000Mhz on 1.5v RAM would obviously be much more difficult than getting 1600Mhz 2000Mhz on 1.25v RAM.

If you're not looking to overclock your RAM, I'd say it wouldn't be worth spending the extra money.

Thanks a lot! +rep

I guess I'll go with the CL8 Cosair Vengeance for 78 euros then.

Honestly, anything that's 1.5v and 9-9-9-24 for DDR3-1600 will work just fine. Tighter timings is better, higher speed is better....sure. But I can't tell a single bit of difference from 1600 @ 9-9-9-24 and 2133 @ 9-10-9-24. The memory controller on Sandy Bridge is quite good, so you really won't notice a difference between "crap" RAM and high end with it.

I don't know that I'd go that far. But the hours of tweaking on ram don't exist. Buy the fastest you can afford.

Actually, you can still tweak your RAM just fine with Sandy Bridge. I'm at 1933, 9-10-9-24-1T right now, 1.65v. Rock solid stable.

I could have cheaped out and used the XMP profile for 1600. But its always nice to max out your performance, whether its noticeable or not.
