magg Posted March 25, 2005 Posted March 25, 2005 I'm running right now at 256x9 with 1.456vCore and my RAM is running 1:1 at 2.5-3-3-6. Now, I've heard from some people that running your tRAS at 7 is actually better for AMD64 systems, it supposedly ups your bandwidth. I've also heard the same thing said for changing it up to 8. Anybody have any thoughts on this? If it makes a difference, I plan to take this OC to about 2.4ish [270/275x9] and keep it at 1:1, if possible. Thanks in advance. :nod: Quote Share this post Link to post Share on other sites More sharing options...
THunDA Posted March 25, 2005 Posted March 25, 2005 Very easy to find which is better.. Try each yourself and bench to see the difference.. Everyones config will react different even with the same hardware so the above is the ONLY way to see which timing is more optimal for YOUR rig..

Adjusting the tRAS depends on the stability of your system. If it's stable, you could always lower it to give you better performance but by doing so may make your system unstable. Check this out, it gives a very good explanation to memory OCing and tweaking your RAM settings. Quote Share this post Link to post Share on other sites More sharing options...
RyderOCZ Posted March 25, 2005 Posted March 25, 2005 Magg, You will have to experiment with Sandra/Everest to see if one setting works better on your system. I have found it to vary from CPU to CPU and also with different FSB settings. Once you have achieved your desired FSB, use A64 tweaker to change the tRAS value and look for max bandwidth, then reboot and set it in bios Quote Share this post Link to post Share on other sites More sharing options...
THunDA Posted March 25, 2005 Posted March 25, 2005 Lower is always better. Not always.. Most people found that Tras of 11 for NF2 mobo's give the best BW.. and most people have found 8 or 10 to be most optimal with a64's.. But really it comes down to testing yourself and see which is best for your setup.. Quote Share this post Link to post Share on other sites More sharing options...
ridikolous Posted March 25, 2005 Posted March 25, 2005 0 gives me a much better bandwidth then all the other numbers. so some of urs might vary.. just takes a lil testing and patients. Quote Share this post Link to post Share on other sites More sharing options...
Poisonsnak Posted March 26, 2005 Posted March 26, 2005 zero for tRAS? I think you must be thinking of a different timing. If you set tRAS too low it can cause hard drive corruption, read this document from mushkin: http://www.mushkin.com/mushkin/pop-up/latencies.htm Quote Share this post Link to post Share on other sites More sharing options...

But MANY peeps have been using 00 for tras on a64's.. Including me.. Quote Share this post Link to post Share on other sites More sharing options...
ridikolous Posted March 26, 2005 Posted March 26, 2005 i've been using "0" for quite a while now, everything works fine. if i mess up my hdd. ill just buy a new one. i like zero it performs better den 5-10 for me... Quote Share this post Link to post Share on other sites More sharing options...

If you set tRAS too low it can cause hard drive corruption, read this document from mushkin: http://www.mushkin.com/mushkin/pop-up/latencies.htm This is the first time in a very LONG time that somebody mentions the "tras rule" I used to follow in my Tbird days. I like to play it safe so I tend to follow with the A64 too cause OS corruption is the thing I fear the most. Regards Quote Share this post Link to post Share on other sites More sharing options...
Guest nitro Posted March 26, 2005 Posted March 26, 2005 I have tried every one from 5-10. Not much difference for me. 6 gives me about 5 more in sandra. Quote Share this post Link to post Share on other sites More sharing options...

Huh, well what can I say if some one like you is doing it then I guess I must be wrong. I wonder if this is caused because the memory controller is on-die now? That document from mushkin must be fundamentally wrong somehow because if the RAM is only 'open for read' as long as tRAS then with it set to 0 you can't use the ram, period. Maybe if you set it too low the CPU overrides it somehow? Since the controller is on-die now maybe it gets to ignore you from time to time. Do apps like memtest86 report it as 00 if you set it to that? I'm still afraid to try. Thanks for the info though man. Quote Share this post Link to post Share on other sites More sharing options...
