Lord Chaos Posted November 22, 2006 Share Posted November 22, 2006 I am looking for a way to up the performance of my memory on my system, I believe my system stats are listed in profile (but I've added them below for convenience), if anyone could help me figure out better manual settings for my memory (cooling shouldn't be a problem, the case is well ventilated and cool), but since memory settings have become so much more complicated over the years I have no idea what they all means and whats optimal settings for my Corsair XMS 2x2048TWX400C2 memory (4 Gb total) This is an Asus motherboard, using nvidia nForce4: Memclock 200 Mhz CAS Latency 3.0 TRAS - 8 TRP - 3 TRCD - 3 TRRD - 2 TRC - 11 TRFC - 13 TRWT - 4 all set on auto Then there's TREF 7,8 us TWCL 1 R/W Queue Bypass Control 8 Bypass Limit 4 Idle Cycle Limit 16 Dynamic Idle Cycle Center - Enabled DDR Driving Strength - Weak Enable 32 Byte Granularity - Disabled TWR 3 DDR InputStrobe Skew Disabled DDR Data Driving Strength - Disabled Read Preample 5,5 ns Asyc Latency 7 ns Bank Interleaving Auto K8 to NB Auto (can be set to <number>X) Link With Auto (same as above) SB to NB 5x These are the settings, how do I optimize these, any recomended settings for optimal performace using this ram?

Wired Posted November 22, 2006 Share Posted November 22, 2006 2x2 Gb TwinX XMS (2048TWX400C2) does not exist. Do you mean you have 2 packs of TwinX2048-3200C2? Link to comment Share on other sites More sharing options...
Lord Chaos Posted November 22, 2006 Author Share Posted November 22, 2006 Yes, sorry, was looking at the wrong label. 2 packs of TWINX2048-3200C2 4x1 Gb modules. After trying the CAS 2.0, the system became very unstable and blue screened. Don't know if it just doesn't support CAS 2.0 or other settings needs to be set properly too at the same time.

Wired Posted November 22, 2006 Share Posted November 22, 2006 ONE pair supports 2-3-3-6, but they're not tested in TWO pairs. If they run 3-3-3-8 fine, then I doubt they'd get much tighter. Link to comment Share on other sites More sharing options...
Lord Chaos Posted November 23, 2006 Author Share Posted November 23, 2006 Not sure which settings those refer to. So having 4 Gb instead of 2 Gb degrades their performance? What about all the remaining settings? Link to comment Share on other sites More sharing options...
BMGundam Posted November 23, 2006 Share Posted November 23, 2006 You didn't list the most important setting, Command Rate. If it's not at 2T, you probably aren't going to be very stable. K8 to NB, set to 3x if overclocking and 5x for stock. Leaving it at 5x doesn't really help, it just increases the NB temp. Link width, set to 16/16 Link to comment Share on other sites More sharing options...
Lord Chaos Posted November 23, 2006 Author Share Posted November 23, 2006 Thats all the settings there are, I can't find anything called "Command Rate" :( Thanks for the other tweak suggestions though, I'll try them out. :) Link to comment Share on other sites More sharing options...
Lord Chaos Posted November 28, 2006 Author Share Posted November 28, 2006 I found the command rate, its set at 2T (found it in the memtestx86 program), tried changing it to 1T. But that caused the machine to freeze. Maybe its already at its max performance...too bad I can't upgrade motherboard and processor without needing new RAM it seems. Did try and go from 200 Mhz to 210 Mhz, that seems to be stable so far. Link to comment Share on other sites More sharing options...
DerekT Posted November 30, 2006 Share Posted November 30, 2006 Your specs do not show what X2 you have. What is your multiplier or your model of X2? Link to comment Share on other sites More sharing options...
StoneRhino Posted December 2, 2006 Share Posted December 2, 2006 I would like a tweak version of the list that lord posted before. I have the same MB and memory as him (1 pair only thou 2GB total). This is the original list: Memclock 200 Mhz CAS Latency 3.0 TRAS - 8 TRP - 3 TRCD - 3 TRRD - 2 TRC - 11 TRFC - 13 TRWT - 4 all set on auto Then there's TREF 7,8 us TWCL 1 R/W Queue Bypass Control 8 Bypass Limit 4 Idle Cycle Limit 16 Dynamic Idle Cycle Center - Enabled DDR Driving Strength - Weak Enable 32 Byte Granularity - Disabled TWR 3 DDR InputStrobe Skew Disabled DDR Data Driving Strength - Disabled Read Preample 5,5 ns Asyc Latency 7 ns Bank Interleaving Auto K8 to NB Auto (can be set to <number>X) Link With Auto (same as above) SB to NB 5x Any help would be appreciated.

DerekT Posted December 18, 2006 Share Posted December 18, 2006 I would like a tweak version of the list that lord posted before. I have the same MB and memory as him (1 pair only thou 2GB total). Memclock 200 Mhz CAS Latency 2.5 TRAS - 7 TRP - 3 TRCD - 3 TRRD - 2 TRC - 11 TRFC - 13 TRWT - 4 You can leave your other settings as is. Link to comment Share on other sites More sharing options...
