EvilDead Posted August 12, 2005 Posted August 12, 2005 Hello all, My machine was running rock solid for 6 months. 2 weeks ago some of my applications started crashing so I ran Memtest 86+ v 1.60. I found that one of my sticks was getting errors while the other one would run 10+ hours no problem. I sent both the sticks in and received a replacement set only to have the same problem occur. I tested each stick individually in slots 1 & 2. The RAM settings are set to the defaults in the BIOS. Should I try adjusting these? Is it likely that they sent me back another bad stick?

Sharp Posted August 12, 2005 Posted August 12, 2005 Hello, Are all 4 power connectors plugged into the board? Place the memory in the orange slots. Set the memory voltage to 2.8v. (model/part number for the memory?) Share this post Link to post Share on other sites More sharing options...
EvilDead Posted August 12, 2005 Posted August 12, 2005 Hello, Are all 4 power connectors plugged into the board? Place the memory in the orange slots. Set the memory voltage to 2.8v. (model/part number for the memory?) At work right now but I will try upping the voltage to 2.8 when I get home. All the power connectors are plugged in. I have tried the RAM individually in each slot. Memory: mushkin SP3200 512MB 184-Pin DDR SDRAM Unbuffered DDR 400 (PC 3200) System Memory (Cheap stuff) * Model #: 991093 http://www.newegg.com/Product/Product.asp?...N82E16820146219 Thanks for your suggestions. I will reply with my results on the voltage this evening. Share this post Link to post Share on other sites More sharing options...
EvilDead Posted August 15, 2005 Posted August 15, 2005 I didnt have much time to work on the computer over the weekend but I upped the voltage to 2.7 and it lowered the number of errors on Memtest. I am currently trying with 2.8. Share this post Link to post Share on other sites More sharing options...
EvilDead Posted August 15, 2005 Posted August 15, 2005 Are there any other suggestions in case the 2.8v does not solve the problem? My memory timings are 3-3-3-8 1T. Should I play around with any of these? If I have to loosen these timings to solve the problem does that mean that my RAM is defective?

Sharp Posted August 16, 2005 Posted August 16, 2005 Hello, No, If the Default BIOS settings are to low (tight) it means you need to adjust the settings as tight timings can cauase errors in memtest. All slow memory modules require loose timings. Try these settings. GENIE BIOS Setting >DRAM Configuration..................Press Enter = New Menu FSB BUS Frequency....................200 DRAM Voltage Control.................2.8v GENIE BIOS Setting >DRAM Configuration DRAM Frequency Set (MHZ).............200 (DRAM/FSB:1/01) Command per clock (CPC)..............Disabled Cas latency (tCL)....................3 RAS to CAS delay (tRCD)..............3 Min RAS active time (tRAS)...........8 Row precharge time (tRP).............3 Row cycle time (tRC).................11 Row refresh cycle time(tRFC).........14 Row to Row delay (tRRD)..............3 Write recovery time (tWR)............3 Write to read delay (tWTR)...........2 Read to write delay (tRWT)...........2 Refresh period (tREF)................AUTO Write CAS latency (tWCL).............1 DRAM Bank Interleave.................Enabled DQS Skew Control.....................Decrease Skew DQS Skew Value.......................0 DRAM Drive Strength..................AUTO DRAM Data Drive Strength.............AUTO Max Async Latency....................6ns Dram Response........................Normal Read Preamble Time...................5ns Idle Cycle Limit.....................AUTO Dynamic Counter......................Disabled R/W Queue Bypass.....................AUTO Bypass Max...........................AUTO 32 Byte Granularity..................Disable (8 Bursts) Share this post Link to post Share on other sites More sharing options...
DeathTouchWIlly Posted August 16, 2005 Posted August 16, 2005 Ditto on the 2T change for the CPC. I had oodles of crashing/freezing with my OCZ memory but then I relaxed my CPC to disabled and I could pwn on BF2 for hours. Ok maybe I got bombed to pieces by 12 year olds in jets but at least I didn't BSOD while it happened. Share this post Link to post Share on other sites More sharing options...
EvilDead Posted August 16, 2005 Posted August 16, 2005 Your input is very much appreciated. Can't wait to try these settings after work. Thanks again. Share this post Link to post Share on other sites More sharing options...
Guest nova Posted August 16, 2005 Posted August 16, 2005 Some more input for you,.... I have two of these Mushkin sticks in the kids' game machine. I tried them in my DFI rig with the 623-3 bios and everything in Auto,... to my suprize they outperformed (with no tweaking) all my other mem except my Mushkin Black. I also have some HyperX, OCZ Platinum, and Samsung that I have put in my DFI and played with. Might be worth a minute of your time to throw everything (memory wise) in auto and see what happens.

EvilDead Posted August 17, 2005 Posted August 17, 2005 an update: Tested "good" stick alone again and it went 13 hours optimized defaults no problems. (yesterday while I was at work) Nova I put the second stick back in. All settings on Auto caused Memtest to freeze after six minutes. Sharp I am running your settings today and will see what happens. It had passed 2x OK when I left the house this morning. How much of a performance hit does the ram take by setting them to 2T?

Sharp Posted August 17, 2005 Posted August 17, 2005 Hello, With 2T, my memory performance in Everest READ = decreased by ~200MB/s (5621MBs) WRITE = decreased by ~200MB/s (2235MBs) LATENCY = increased by 5ns (49.3ns) With 1T, my memory performance in Everest READ = 5869MB/s WRITE = 2467MB/s LATENCY = 44ns And in Sisoft sandra unbuffered scores, 2T ALU = Decreased by ~300MB/s FPU = Decrease by ~200MB/s So it does make a difference. With a higher frequency CPU the impact would be bigger. But with slow memory such as 3-3-3-8, the performance loss may be very small.

Guest Tyler Posted August 17, 2005 Posted August 17, 2005 It doesnt make a difference in games though, just synthetic benches. At least for me. Share this post Link to post Share on other sites More sharing options...
