Memory Timing Question

post #1 of 5
Thread Starter 
Hello,

I'll start off by saying I don't really have a firm grasp on memory timings. I've read a few guides on these forums, but I'm still pretty unknown to the concept.

When I first built my computer, which was about six months ago. I misplaced the packaging my ram came in. When it came time to adjust the timings in my bios, I wasn't sure what to put. I looked my ram up on newegg, and the first thing I saw was the timings should be 8-8-8-21. So I set my timings to that.

Today I found my ram packaging, and after looking at it. It says the timings should actually be 8-8-8-24. My question is, since I have been running my ram at 8-8-8-21 without any apparent problems for about 6 months now, should I leave it at that? Or should I go into the bios and set it to 8-8-8-24. The reason I ask is because I've never really overclocked / tinkered with my ram before. From what I understand lower "tighter" timings are better than higher "looser".

For Reference my components are :
Mobo : Asus Crosshair IV
CPU : Amd 1100T
Ram : G.Skill 4gb (2gb x2) DDR3 1333

Thanks in advance for any input.

leave them like that, or try 7-7-7-21(you may need a RAM voltage bump)

For amd systems yes tighter timings are better
meaning lower latency...
you could probably get down to an even 7-7-7-21 as IOSFiNI Stated..

But you might need that extra juice...

Another recommendation...
On your board
Set your NB to 3000 even..
and your HT link to 2000
That should be your base to start from...will help out a lil bit
but yes Tigheter timings are better on amd systems..less work

Thanks guys.

I have my ram running at 7-7-21 right now. Everything seems stable, but I'm going to let a Prime 95 test run for a while just to make sure.

Ya deffinitly do that for a good while..
could just do memtest for it but it seems like that ram can do cl7 easy

Oh another suggestion for ya pillar
you should deffinitly fill out your system specs

Go to UserCP-- and on the left hand side youll see that it says add new system or edit system..click that and fill in the blanks...will help greatly for future helping with any problems you may come across
