how do i tighten RAM latencies?

rjpogi · Dec 8, 2004, 08:11 AM

do i lower them or make them higher?
my current latencies are 2.5-3-3-6 in 1T

tightening latency can make the system unstable, especially if you OC. you would have to disable SPD then adjust from there.

think he knows that i believe what hes asking is does he try

higher as in 3.5-4-4-7

or

lower as in 1.5-2-2-5

and TBH i have no idea

"tightening" is lowering the latency. I have never seen ram run at CAS 1.5, so don't even try that. 2.5-3-3-6 isn't that bad to begin with. 2-2-2-5 would be the best, but you would have to have some damn good ram like Crucial Ballistix or Corsair XMS.

the fact that you didn't know whether to increase or decrease latency makes me wonder if you should really be screwing with that. like I said, changing timings can cause your system to crash or not boot at all. you'd have to reset the bios at that point. I'd recommend you let the SPD auto-assign the timings.

I would typically also leave it to SPD and maybe try pushing the FSB a little bit higher instead. A lowered RAM latency would likely limit the FSB overclocking ability.

Conversely, loosening timings may give you more OCing headroom.

try putting the 6 up to 10 and lowering your CAS

so you have: 2-3-3-10

the cas with improve performance and the 10 on TRAS will improve your stability without much of an effect on performance, the CAS change will more than make up for that

if timings are set to 2-3-3-10, and there's minimal impact on performance, then what's the point that? When making timings tighter, you want a performance increase. When i tighten my timings, i have mine set to 2-2-2-6 @ 2.7v. My FPS go up about 10, and my benchmark scores go up significantly.

rjpogi · Dec 10, 2004, 09:04 AM

but my the maximum in my bios is 6, i can't set it to 10, is it bad?

CDsDontBurn · Dec 10, 2004, 10:09 AM

check to see if there is a newer version for your BIOS. if there is, then it may allow you to set your TRAS higher than 6.

rjpogi · Dec 12, 2004, 10:08 AM

ha! i set my latencies to 2-2-2-5 and it's very stable! oh joy!

refraction · Dec 12, 2004, 11:44 AM

it depends what your ram can handle i suppose.

them timings i had on my NF7-S motherboard with 333mhz ram.

i wasnt complaining tho cos i got it up to 410mhz stable :P
