ThreeFlow Posted August 23, 2006 Posted August 23, 2006 Hi folks, I would really appreciate a bit of help with this issue I am having. Just bought some new ram, OCZ5002048EBPE-K 2x1GB which uses Infineon CE-6 chips rated at DDR500. I've searched the forums and found one thread where someone was having problems getting this ram stable, people suggested running the memory on a divider instead of 1:1 so I am now doing that, and it doesn't affect the situation I'm experiencing. Since this RAM has been installed into my system, at any period of time (seems to be purely random..... at first I thought it was only when the CPU or memory was loaded with work but now I've had it happen right in front of me when the computer was idle...) it will freeze up and 5 seconds later the monitor turns black (with the power button led switching from green to flashing orange indicating it is in standby mode.... same mode as when the PC itself is shut off but the monitor is not). When this happens, the computer itself is still on, but its just a black screen so am forced to reboot. I have even tried underclocking this memory from its stock speed and it doesn't seem to help. THe thread where the other guy had a problem with stability is here: http://www.dfi-street.com/forum/showthread...t=infineon+ce-6 I've read his settings on when he managed to get it stable, tried copying them, then tweaking them a bit (he's using a different motherboard than I am though so....) but I still can't figure out this problem. Can anyone offer any guidance? Thanks in advance, -Threeflow Quote Share this post Link to post Share on other sites More sharing options...
cuoficr Posted August 23, 2006 Posted August 23, 2006 Try these settings from the OCZ support forums? Also try running 1 stick at a time. It's possible one could be bad. http://www.bleedinedge.com/forum/showpost....971&postcount=3 Quote Share this post Link to post Share on other sites More sharing options...
Praz Posted August 23, 2006 Posted August 23, 2006 Post a screenshot of A64Info showing your timings. Also your voltage. Normally OCZ EB sticks are as solid as a rock. Quote Share this post Link to post Share on other sites More sharing options...
Sharp Posted August 23, 2006 Posted August 23, 2006 Hello, Memory in the orange slots, Have you ran metest yet? Quote Share this post Link to post Share on other sites More sharing options...
Kingfisher Posted August 23, 2006 Posted August 23, 2006 Hello, These are my current RAM timings. DRAM Frequency Set............................ - 180=RAM/FSB:09/10 Command Per Clock (CPC)....................... - Enable CAS Latency Control (Tcl)..................... - 03 RAS# to CAS# delay (Trcd)..................... - 03 Bus Clocks Min RAS# active time (Tras)................... - 08 Bus Clocks Row precharge time (Trp)...................... - 02 Bus Clocks Row Cycle time (Trc).......................... - 08 Bus Clocks Row refresh cyc time (Trfc)................... - 16 Bus Clocks Row to Row delay (Trrd)....................... - 03 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 DRAM Bank Interleave.......................... - Enabled DQS Skew Control.............................. - Auto DQS Skew Value................................ - 0 DRAM Drive Strength........................... - level 08 DRAM Data Drive Strength...................... - level 2(reduce 30%) Max Async Latency............................. - 8ns DRAM Response Time............................ - Fast Read Preamble Time............................ - 6ns IdleCycle Limit............................... - 256 Cycles Dynamic Counter............................... - Disable R/W Queue Bypass.............................. - 16 x Bypass Max.................................... - 04 x 32 Byte Granularity........................... - Disable(4 Bursts) I tried other timings for this memory and found I could not, at least for now, get them to run over 250 HTT 3D stable. I could get them to boot into windows at 270HTT and pass over 4 hours of memtest but when I would test DirectDraw or something it would do as you explained. Good Luck to you.

Praz Posted August 23, 2006 Posted August 23, 2006 Any of these settings that you have already tried please ignore. Set Trc to 7 and Trfc to 13. At 250 this memory ought to be happy with this running on an Expert board. Try DRAM Drive Strength at 4. Set memory divider to 1/1 and processor at 250x10. Run 8 - 10 passes of Memtest #5 and #8 then try 3d Mark. Quote Share this post Link to post Share on other sites More sharing options...
Kingfisher Posted August 23, 2006 Posted August 23, 2006 That's great praz, but he is not using an Expert. Quote Share this post Link to post Share on other sites More sharing options...
Praz Posted August 23, 2006 Posted August 23, 2006 I apologize. That must be why you posted your timings. Quote Share this post Link to post Share on other sites More sharing options...
Mindflux Posted August 23, 2006 Posted August 23, 2006 have you tried reseating and dusting out the ram slots and video card? Quote Share this post Link to post Share on other sites More sharing options...
Kingfisher Posted August 23, 2006 Posted August 23, 2006 I only posted my timings because the OP referred to my thread on this ram. Just trying to help. Quote Share this post Link to post Share on other sites More sharing options...
ThreeFlow Posted August 24, 2006 Posted August 24, 2006 Try these settings from the OCZ support forums? Also try running 1 stick at a time. It's possible one could be bad. http://www.bleedinedge.com/forum/showpost....971&postcount=3 I will follow your advice and try this, thank you! Post a screenshot of A64Info showing your timings. Also your voltage. Normally OCZ EB sticks are as solid as a rock. Click image for a larger version! I use the same settings above trying to run at 250MHz and also 260MHz. I've also had the voltage at up to 2.74v (I haven't pushed it up to 2.8, though I may try this). 260MHz would be optimal for me as 2600MHz is the sweet spot for my processor, just makes it much easier that way. Hello, Memory in the orange slots, Have you ran metest yet? Yes I have both sticks in the orange slots, though I have yet to run memtest on them. I will do this very soon! Hello, These are my current RAM timings. (.....) I tried other timings for this memory and found I could not, at least for now, get them to run over 250 HTT 3D stable. I could get them to boot into windows at 270HTT and pass over 4 hours of memtest but when I would test DirectDraw or something it would do as you explained. Good Luck to you. I haven't even run any 3D tests since installing this ram, only video/audio ripping and encoding. Thank you for posting your timings, I will give them a try! To all those who took their time to read my problem and post feedback and advice, you have my gratitude! Thank you all so very much, I will take all this information into consideration and with luck will have the situation sorted soon. Thanks!!

ThreeFlow Posted August 25, 2006 Posted August 25, 2006 I ran memtest with same settings above but at 260MHz and it passed 17 FULL LOOPS with no errors. The memory is still causing the system to freeze and force a manual reboot within windows at those settings when the memory is being utilized during video encoding. I even upped the voltage to 2.8v and it did not improve stability. I dropped the memory speed to 245MHz and the problem was still apparent. Backed it off again to 241MHz and it appears to be OK... I have still yet to run the sticks one at a time, I will do this soon. Quote Share this post Link to post Share on other sites More sharing options...
