Not sure of clock and timings for best RAM performance

post #1 of 10
Thread Starter 
I'm pretty uneducated on the subject of memory clocks and timings. I was wondering what would be the best settings for my current rig in order to get the best performance out of it. Here's my memory

G.Skill Ripjaws DDR3 1333

Thanks for any help you can offer.

I favour timings over speed. Push the speed up at the same timings. see if you can get to 1600MHz at 1.65 volts.

Adjusting timing's is more for tweaking higher OC's, adjusted timings bearly even score you anymore points in 3dMark. I would leave them.

Well, something just doesn't seem right. I only scored a 5.9 on the Windows index on my memory. On my old DDR2 memory and old mobo I scored higher than this. Here's a shot of my CPU-Z memory screen. Obviously this processor has a locked multiplier, but I've bumped the BLCK up to 105.2 and managed a 3471 Mhz clock speed. Hell, even as merely a dual core, it still managed a SuperPI 32M in 10m20s, which is pretty damn good IMO since it smokes pretty much all of the AMD 4 core runs. I just want to get this memory issue straightened out.

Put your Command Rate (CR) to 1T.
post #6 of 10
why 1t
post #7 of 10
1T has faster response than 2T. Not all DIMM's can do it, but most can today.

@OP


Your RAM is currently running at CL8 - that means waiting 8 full clock cycles before even accessing the RAM functions. with your DDR2 you were probably running CL5 or CL6, big big big improvements over CL8. Most DDR3 @ 1600 is CL8/CL9 - Most DDR3 1333 is CL7 or lower. You should aim for CL6 if possible, even CL5 if the DIMMS can handle it (doubt it).

So set it to 1T and change the CL to 6, and leave everything else? I'll give it a try. Thanks +1

Okay... Well.... I was able to get it to run at 1600 Mhz without any increase in voltage, but when it was at 1333, any time I tried to lower the CL just 1 number, it wouldn't POST. Now, with it running at 1600, timings are 9-11-11-29, and I can't lower CL at all without failure to post. I guess this means I'm stuck with what I've got? If DDR3 and higher speeds mean slower response... What's the point of having it?

It's fine. The bandwidth will make up for at the time being. You're fine.
