Help lower timing.

post #1 of 13
Thread Starter 
trying to reach 3.0ghz, Net step is to lower timing on ram. Havent ever done that before.
If its 4-4-4-12, what should I set it at next?

Hmmm, did your RAM overclock as you upped your FSB, or did you set it to a lower speed? Like, is your Ram a 1:1 ratio or something else?

If your ram is over 800MHz, don't expect to get too high a timings...on Intel systems, memory bandwidth is usually more important than timings, so i would try getting the memory to the highest speed...then adjust the timings...don't go over about 5-5-5-15 or so....You'll probably have to up the memory voltage by one or two steps, but don't go anything over that...

Personally I like to use memset to change timings. You can change a single timing and then run memtest inwindows to see ifyou get any errors. It is quick but you potentially run the risk of corrupting your install (potentially).

The other safer method is to get memset installed on a floppy/cd/usb drive and go into bios and start lowering yourtimings then run a little memtest to see if its stable then go back and keep doing it till you get thetightest timings that dont give you any errors.

Ive been having trouble with the comp and couldnt go over 380mhz fsb. I just recently found out different options to try and Ive tried all of them so Im going with the last.
I want 400fsb/800mhz ram. (1:1)

Well if you are satisfied with your overclock, then yup, it's time to tighten those timings. You can do what is suggested above, or go into your system's BIOS at startup, and find the RAM settings...don't go way down, cause it's not going to work ... find some of the RAM FAQ's on here and read up on what the timings actually mean, and change the timings that really matter.

If you are still trying to overclock, loosen the RAM timings, set a divider on the RAM to make it go a bit slower if it is way over it's rated 800MHz, and you should probably get a bit higher...not sure what the stock FSB is for the new intel's as i am still on a pentium 4 processor, lol.

Im not satisfied with the OC.. i want 400mhz fsb and its not letting me achieve that so Im asking about ram timing. 5-5-5-15 is looser then 4-4-4-12??? Just making sure thats how this thing works....

it shouldnt be the ram voltage because it is 800mhz ram. doesnt that mean that voltage shouldnt be an issue and it should run at that speed if set?

The Ram's voltage is what it needs to run at stock speed and timings...you will probably have to up the stock voltage to a jump or two higher to get tighter settings....and yes, 5-5-5-15 is a looser timing than 4-4-4-12...i was just suggesting loosening the timings until you overclocked your processor to its potential, then going back and finding the perfect RAM timing.

Hi.

Here is a link that describes Timings and Latencies.

...no offense, but knowing what the numbers refer to will assist in your success...

Typically overclocking RAM will require additional voltage and sometimes looser timings.
