Kerracher Posted October 19, 2007 Posted October 19, 2007 Hi All I have a DFI Lanparty SLI-DR Nforce 4 motherboard. I have 2x1GB PC3200 DDR 400 Hynix ram sticks. My problem is I really don't know what timings to use to get some more Mhz out of the RAM. Currently I have them at 214mhz with 2 4 8 4 and 0648 refresh cycle. I really just need some advice for timings so I can get them running at 237 to 240mhz as my CPU I have can go to 2640 (240x11). I just don't want to use dividers on the RAM anymore and actually want to push as many Mhz out of it as I can. If someone can suggest a full list of timings that would be great.

CrimsonCleaver Posted October 19, 2007 Posted October 19, 2007 What's the best settings to increase to loosen timings? Share this post Link to post Share on other sites More sharing options...
Kerracher Posted October 20, 2007 Posted October 20, 2007 Well my problem was I couldn't get Vista to boot, but it was due to not enabling Odd Divisor select. I think I need to loosen the timings somewhat as I get bluescreens after a while. What's the best setting to increase to add stability?

dr_bowtie Posted October 20, 2007 Posted October 20, 2007 Just test the ram out with memtest in test #5 and try different settings while upping the bus....thats the best way to do it.. Share this post Link to post Share on other sites More sharing options...
Kerracher Posted October 21, 2007 Posted October 21, 2007 Hi there, Thanks for the replies. What's a good refresh period to use for this RAM? Is there anywhere where I can find a list of fully stable setting and start from there? It seems too trial and error at the moment (with more error than anything). Thanks again Share this post Link to post Share on other sites More sharing options...
Sharp Posted October 21, 2007 Posted October 21, 2007 Leave Tref to around 1560-2064. Overclocking is never simple and with Hynix chips on a 939 CPU is is going to be hard. Share this post Link to post Share on other sites More sharing options...
Kerracher Posted October 21, 2007 Posted October 21, 2007 Thanks for the reply, I'll give those Tref values a go. Really frustrating to find settings that work. I'm trying to contact people on loads of different forums who reported getting this RAM up to 270mhz. Just in their posts the full timings weren't stated Share this post Link to post Share on other sites More sharing options...
Kerracher Posted November 1, 2007 Posted November 1, 2007 Hi All, I'm having a bit of sucess with the following settings. Not getting BSODs anymore but instead AppCrashes (in XP) of Crysis SP demo. The demo is fine when at stock so obviously the timings are an issue. Can anyone offer any advice on how to tweak these settings a bit more, something to increase stability to avoid the AppCrashes? 200 1:1 FSB 240 CPC Enable CAS 3 or 2.5 - getting crashes less often with 2.5 tRCD 4 tRAS 10 - have also tried 12 tRP 4 tRC 16 tRFC 18 tRRD Auto - It's setting to 2, which seems to be far more stable than 3 for some reason tWR 3 tWTR 2 tRWT Auto Refresh Period 3120 Write Cas 1 Bank Interleave Enabled DQS skew decrease DQS 0 DRAM drive Auto DRAM data drive Level 1 Max Async 13 Dram Response normal Read Preamble 9 Idle Cycle 256 Dynamic Counter Disable R/W 16x Bypass 7x 32 byte Disable Share this post Link to post Share on other sites More sharing options...
