I've just replaced {Crucial 2 x 512mb PC2|5300|ddr667} with, {OCZ 2 x 1gb
PC2|6400|ddr400} and the OCZ SPD chip reveals to CPU-Z that timings for
running it at 200mhz would be 5.0,5,5,15,23 (CAS#,tRCD,tRP,tRAS,tRC
repectively) ...at 1.8volts
....now the CPU-Z "Memory" tab, (showing current timings), does not show the
current voltage setting !
....and the specs. for the OCZ memory say that it's fine to run it with
timings of 4.0,4,4,4,12,16 (CAS#,tRCD,tRP,tRAS,tRC repectively),
During the past few weeks I've been rummaging, and Googling, and trying to
find more information on this subject, specifically on Voltage.
....the little labels on the two OCZ modules say 4-4-4-12 @ 2.1v , and my
motherboard bios options for setting for RAM voltage are,
(annoyingly/inadequately), Low,Normal,High,Extra High !!!
....having spotted people in various forums that have had memory errors, when
trying to use higher performance latencies, on "higher performance" memory /
using a "normal" voltage setting - I've sort of gleaned that one has to set
in bios a higher voltage for the memory modules ...e.g. the 2.1 volts as on
the OCZ labels !!!
Anyhoooo, I've set RAM voltage in bios to "High" and latencies to
4.0,4,4,4,12,16 (CAS#,tRCD,tRP,tRAS,tRC repectively),
....and run MemTest for quite some time, and all seems well !
....but, does anyone know what the actual voltages are for
Low,Normal,High,Extra High ?
( it's a http://www.asrock.com/mb/overview.asp?Model=ALiveNF6G-VSTA&s=AM2
btw )
any tips, appreciated ....Paul ?
...oh ! ...and before all the clever clogs pile in with comments like,
....( "you won't notice hardly any difference - regarding "higher
performance" memory ....unless you're gaming... etc." ), ...
RUBBISH, my old "main PC" (Conroe865pe/D935-(2x3.2ghz cpu)) had 2x512mb's of
Crucial pc3200 CL6 etc. (so that page interleave was working - dual channel
if you prefer), now it has 4x512mb Corsair 2-3-2-6 184 pin memory modules
in it, and EVERYTHING is much more responsive. ...even hibernate and resume
from hibernation, seems faster with 2gb's of Corsair memory than it was with
1gb of Crucial, despite the machine having to write a 2gb RAM snapshot to
hiberfil.sys, instead of a 1gb sized one !!!
