Hey guys. I just got a new motherboard that finally has options for >2.8v RAM voltage (3.0 and 3.2) -- i am curious; is there a real benefit to be gained by upping the voltage to 3v or so? I have a pair of XMS 3200LL modules, rated at 2-2-2-5-1T @ 3200 -- they have been run @ 2-2-2-5-1t up to about 225mhz no problem. I did a search and found nothing about max voltages for these chips, or what (if any) improvements to speed can be made by upping the voltage, but i'm in a position now where i'm stuck @ 1T and i want to get as much out of these sticks as i can (@ 1t ;))

Any input would be much appreciated
 
that stuff is typically tccd.. it typically doesn't need a lot of voltage, and in some cases, will actually start slowing down if you give it too much
 
Roger that; i think the stickers say rated @ 2.6v. Would you, then, consider 2.8v a realistic maximum? I did a search but can't find anything concrete on what exactly these chips are and what the ideal voltage is...
 
i wouldn't go over 2.9v unless you're gutsy and have lots of airflow over em
 
I ran my TCCDs at 2.75v.. I tried 2.8v and 2.85v and it made no diff in OCing ability.
 
i set my tcc5 xms plat to 2.7 and my mb overvolts it to 2.78 which is perfect for it.
anything over 2.9 and it seems to get flaky on me
:)

same here, although since my chips were rated at 2.75v, i decided to up it to 2.85 just to make sure it was stable and it is now
 
Well, let me re-phrase what I said, acutally. I think if had run my TCCDs at 265+mhz then the 2.85 might have helped... but it didn't help be at 250 get the timings any tighter...

word.

and reverant.. tccd isn't like that. instead of being dependant on voltage for more mhz like a lot of ram, it's almost entirely timing based.
 
ok - well - my logic was based on this chart I got from PDP Systems about the XBL (which are TCCD) modules I had

PC3200 (400MHz) 2-2-2-5-1T 2.6-2.7v
PC3500 (436MHz) 2-3-3-6-1T 2.6-2.7v
PC3700 (466MHz) 2-3-3-6-1T 2.7-2.8v
PC4000 (500MHz) 2.5-3-3-7-1T 2.75-2.85v
PC4200 (533MHz) 3-4-4-8-1T 2.85-2.95v

anyways...
 
well.. sorta. it often needs more voltage as mhz goes up, but more voltage won't let you tighten up timings like micron ram :p :D

but.. anyway, you get the point
