DFI Lanparty SLI-DR and 2x1Gb Hynix Ram


Recommended Posts

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.

No idea if this will help, Hynix memory doesn't work that well on the 939 memory controller.

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?

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

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

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
