Sacrifice Mhz for tighter timings?

post #1 of 7
Thread Starter 
I am cheap as hell, so I'm trying to get the most out of the very little that I have.


I can do 5-4-3-9 @812 Mhz.

I can also do 4-3-3-9 @ 670Mhz, but I bet I can still get more clock speed.

So... Is it worth sacrificing clock speed for tighter timings?

Note: only have 2gb of RAM, planning to get another 2gb next year maybe

I suggest trying the SiSoft Sandra suite to test your memory subsystem. You can test the bandwidth in the two cases and see in your particular case how it works out.

My opinion is since you run in single channel 812MHz with looser timings may be desirable since the CPU is bandwidth starved. When you a second memory stick there's more bandwidth available so it may matter more to have tight timings (thus low memory access time).

I see, thanks xD

instead of old ram how about some ddr3?

Patriot Viper Xtreme 4GB 2X2GB DDR3 2000MHZ PC3-16000 9-11-9-27 1.65V

or G.SKILL Ripjaws Series 4GB 1600MHZ 9-9-9-24 1.5V

which one is better? one has better timing, other has higher clock

can you overclock the ripjaws to 2000MHZ with 1.65V?

I'd personally go for the higher clock speed in this case since the timings aren't terribly bad for 800mhz. Tbh there's no right or wrong answer since different programs favor different things

Great suggestion but, way off for my sig rig

What I understand about ram is that a tighter timing increases response time. Great for gaming.

More mhz increases overall bandwith, great for other applications.
