Lackadaisical Posted March 9, 2006 Posted March 9, 2006 I'm looking for some advice for my ram. I would really like to overlcock my cpu to its full potential but the ram is holding me back and I dont have enough money to upgrade right now. My cpu is stable at 2.65ghz with 1.56 vcore. I can run LARGE FFTS in prime for 18+ hours like that. But the minute I try to run 3dmark the system will freeze because I cant get the ram stable even using a divider and having it run below ddr400 speeds. The ram does past MemTest just wont be stable in windows. I have tried quite alot of different settings to try and get the ram to work on a divider. The problem is anything below the 166mhz divider is just not stable at all. I can run the ram fine on the 166mhz divider using timings of 2.5,3,7 with the ram @ ddr400. When I try to use a lower divider the memory is not stable. I have even tried it with timings of 3,4,4,8 and thats running below DDR 400 speeds. I have tried with Dram interleave disabled. I tried upping my Vdimm. I have also tried various drive strength options. Basically I'm looking for advice on things I could try.If not I'll just wait until I have better ram. I know this ram isnt very good so I'm not expecting much but it would be nice If you read this, Thank you for your time. Share this post Link to post Share on other sites More sharing options...
THunDA Posted March 9, 2006 Posted March 9, 2006 Some of the lower dividers (under 166) are just buggy with some cpu's but its not a consistent thing.. sometimes messing with Max Async and Preamble get things stable.. What are you using for all the other timings ? Please post all your dram settings.. Share this post Link to post Share on other sites More sharing options...
Lackadaisical Posted March 9, 2006 Posted March 9, 2006 These are the settings I am currently using in windows. It is perfectly stable. DRAM Configuration Settings: DRAM Frequency Set - 166 Command Per Clock (CPC) - Auto CAS Latency Control (Tcl) - 3 RAS# to CAS# delay (Trcd) - 03 Bus Clocks Min RAS# active time (Tras) - 07 Bus Clocks Row precharge time (Trp) - 03 Bus Clocks Row Cycle time (Trc) - 08 Bus Clocks Row refresh cyc time (Trfc) - 14 Bus Clocks Row to Row delay (Trrd) - 02 Bus Clocks Write recovery time (Twr) - 03 Bus Clocks Write to Read delay (Twtr) - 02 Bus Clocks Read to Write delay (Trwt) - 03 Bus Clocks Refresh Period (Tref) - 3120 Cycles Write CAS Latency (Twcl) - Auto DRAM Bank Interleave - Enabled DQS Skew Control - Auto DQS Skew Value - 0 DRAM Drive Strength - Auto DRAM Data Drive Strength - Auto Max Async Latency - 7 ns DRAM Response Time - Normal Read Preamble Time - 6.5 ns IdleCycle Limit - 256 Cycles Dynamic Counter - Disable R/W Queue Bypass - 16 x Bypass Max - 07 x 32 Byte Granularity - Disable(4 Bursts) Share this post Link to post Share on other sites More sharing options...
Lackadaisical Posted March 15, 2006 Posted March 15, 2006 So does any one have an idea of what settings I should try to play with? If you need any other information please let me know. Share this post Link to post Share on other sites More sharing options...
Radical_53 Posted March 15, 2006 Posted March 15, 2006 So far, I was only lucky with 166 and 133 dividers. All others didn't work properly... But: This also might be a matter of your CPUs IMC... you might want to try a burn-in on those components, like giving high CPU and DRAM voltage to them at standard clocks for a couple of hours. Might help. Share this post Link to post Share on other sites More sharing options...
Lackadaisical Posted March 15, 2006 Posted March 15, 2006 how would excessive voltage at stock settings help? I never really understood that concept, but thanks for the input Share this post Link to post Share on other sites More sharing options...
Radical_53 Posted March 15, 2006 Posted March 15, 2006 Well, you "age" your components with this. Some manufacturers do even burn-in their components before delivery to have lower failure rates or better performance. Like for me, a fresh board or CPU normally doesn't work too well. But after some time they behave much better or work at higher clocks. If you don't want to wait, you do a burn-in to speed-up the aging and to have the components work well right away.

Lackadaisical Posted March 16, 2006 Posted March 16, 2006 Update: I spent about 3 hours today trying to mess with those settings still no dice. Later When I was looking around newegg I found a nice price on the G Skill PC4000 kit. Only $162! so I couldnt resist and I have ordered it http://www.newegg.com/Product/Product.asp?...N82E16820231021 Share this post Link to post Share on other sites More sharing options...
