I'm getting close to ordering the components for a new machine based on the AMD Deneb quad core and had one last question. I'd like to try a little careful overclocking, not only for the performance increase but also to learn how. Nothing extreme, no gaming, just whatever I can get with good stability with the stock heatsink and fan.

I was going to get 8GB on 2x4GB strips but they are all CAS latency 9. The MB has 4 slots for a total of 16GB capacity. Would I be better off going with 4x2GB strips and try to get a lower latency strip like maybe 7?

Thanks for any help you can provide.

P.S. The OS with be Ubuntu 10.04.

Hi,

If there's not much difference in price, it's a good idea to go for RAM that has lower CAS latency; however, the allowable voltage range of the RAM will also be important too.

Here's a good article (even though it's from 2005) that discusses all the components and how you will adjust them to reach higher speed and higher FSB.

Probably the most important thing of all is the motherboard.
Depending on the options and controls in the BIOS, it can help clarify the process, or be a major hindrance.

If the memory is double-sided memory, you will not be able to fill all four slots with out having problems. You either want to use two single-sided memory and two double-sided memory. You could also use four single-sided memory. The single-sided and double-sided memory relates to what you see on the module. If there is a set of chips on one side, then it is single-sided. If there is a set of chips on both sides of the module, then it is double-sided memory.

Just a note, if you set the memory at DDR3-1333, then you are already over clocking one part of your setup. Keep in mind DDR3 voltage is 1.5 volts.

You will need a 3rd-party processor heat sink unless you do not mind the noise.

AMD K10 processors does not have main memory bottlenecks. They just have processor efficiency problems.

anandtech.com and xbitlabs.com are good sites to get information how to over clock processors. They update information how to do over clock systems.

Over clocking a computer and using Linux is not necessary. Add more processors and Linux will take it from there.

Great sites; full of sagely tech. goodness.

Sum1/Electro,

Thanks for the suggestions. I'll definitely verify the RAM voltages and check those web sites. Since the RAM prices are about the same or less than for the 4GB strips, I'll go with the 2GB ones. The pointer about single-sided vs. double-sided was one I hadn't known about.

Thanks again for the help.

Is that 32-bit Ubuntu ? If so, that overclocking won't add up to much, especially with 8 GB or RAM.

If you plan on overclocking the RAM, make sure to get good RAM, something like OCZ or Corsair, otherwise it won't work, maybe get ones with cooling fins, because they can get hot. Almost always you also have to overclock the processor as well, have a good heat sink ...
