Memory Timings X48 DS4

[prichina]

Hi,guys how are you doing.






so ,guys ,i was thinkig maybe it is better to set my memory to work on 333mhz ,as my cpu bus is 333 ...what do u think? And if u think its better that way ,tell my how to proper manualy set in the bios.

Re: Memory Timings X48 DS4

Looks to me like Auto is setting them up properly. I mean they are running at 555-18 and 800Mhz.

Do you want to run them at 667 (333)? If that is what you mean then you can, but it would not be worth it really.

Post your full specs and a link to your ram or the model #, and if you do want to underclock your ram someone can help you with timings for sure. I can myself, but just wanted to be sure what ram you have before advising. If you do post your info and no one helps let me know via PM and I will stop back in and give you some settings.

If not worth it to underclock,then i'll leave it. Thank you.

Hi, again.
So ,I bought corsair twin2x4096-8500C5 G


This is what bugs me,the setting: Refresh to ACT delay in the bios ,what to set? Now its 52.

Re: Memory Timings X48 DS4

Is it set manually or auto for the 52?
I would worrie much less about tRFC and more about Static tRead Value. Use MemSet to see what is it set for(Performance Level) if set auto in BIOS.

No such thing as identical - each pc will be slightly different - but I have Corsair 8500 in an X48-DQ6 with E8500 cpu. Not sure why tRFC would be bugging you tho'.

Mine is probably low, and 52 reasonable. Depends whether you want to push your ram performance. My bios template:



CPU = Model Intel E8500 45nm Dual core
Motherboard = Model, GA-X48-DQ6 Revision 01
BIOS Version = F8E
Ram = 2x2Gig DDR2 TwinX Corsair Dominator 8500C5DF-G

Auto,but that's the only thing i coulnd set on auto if i go setting by setting :)

What do you mean? You cannot set Static tRead VAlue manually?

[prichina]

Re: Memory Timings X48 DS4

the thing is ,everything goes auto when i use auto ,when i use menual i must set setting by setting ,i can not change only the standard timing control manualy,understand? ...i must do everything manual...so ,then,for every setting i can manualy put on auto ,but only for Static tRead Value i must set a value from 0 to 255 ...understand? so here is the new think i desided to set fsb dram ratio 1:1 ,800 mhz ...so to go only 4-4-4-12 with 2.1 ,something to do more or just go with that...i usualy go with the details. anyone?

bye

Re: Memory Timings X48 DS4

Yes I understand.

Re: Memory Timings X48 DS4

You can set manual for the timings to be enabled, then leave any setting you like on auto and set only the ones you want. You do not have to set them all if you don't want to
