Wayne Harney Posted October 4, 2006 Share Posted October 4, 2006 I put together a new E6600 system with a MSI P965 NEO-F board and (2) CORSAIR VALUE SELECT VS1GB533D2 modules, new HD with fresh install of everyting. Nothing but crashes for a week now. I get a "memory heap error" in the vray feedback window. I ran memtest and indeed got errors on one of the modules. I exchanged the module for a new one and am getting errors again both in memtest and the vray feedback window. Even if I take the bad module out basically every time I load a max file I have to close viz, restart it and then load the file or it crashes. Sometimes I have to reboot to get a max file to open. Does anyone have any ideas before I pitch this thing and go back to my X2? Are the value select modules crap? Please help! Link to comment Share on other sites More sharing options...
Greg Hess Posted October 4, 2006 Share Posted October 4, 2006 What is your bios ram divider set to? 667? 533? 400? If its set at 667, change it to 533. Also set the timings and voltage to the spec's of the ram you purchased. The site you purchased from should have specific information on the timing and voltage. If not, you can find it via the model # at corsairs site. Link to comment Share on other sites More sharing options...
Wayne Harney Posted October 4, 2006 Author Share Posted October 4, 2006 Thanks for listening to my rant Greg. I manually set the voltage and timing to the ram's spec. Turns out the problem is limited to viz2007. I reverted back to viz4 and it runs flawlessly. I'm going to try and recreate the scene from scratch in 2007 and see if it runs stable.

Fran Posted October 4, 2006 Share Posted October 4, 2006 Hi Wayne, How can VIZ 2007 possibly cause your modules to fail a memtest? Did they pass after you adjusted the voltage and timing? Link to comment Share on other sites More sharing options...
AJLynn Posted October 4, 2006 Share Posted October 4, 2006 On my MSI board I needed to adjust the RAM voltage - MB defaulted to 1.8V, but RAM was spec'ed at 2.1V. Also, you may need to manually input the timings, especially if you've changed from the default RAM/FSB speed, and you might not be able to use a ratio (FSB:RAM) over 1:1. Mine works fine at 1:1 with the FSB set to 355MHz (this is an overclock), which sets the RAM to 355. I tried 1:1.25, which put the RAM at 444MHz, and it was unstable. Did you set up correctly for dual-channel use? The RAM slots are paired and each pair of slots needs to be the same - e.g., one 1GB DIMM in slots 1 and 3, not slots 1 and 2. The pairs are probably color coded (on mine I'm using one green slot and one orange slot). Link to comment Share on other sites More sharing options...
Greg Hess Posted October 4, 2006 Share Posted October 4, 2006 No problem wayne, sometimes all you need is a good vent! I'd agree with Fran though...you should be getting ZERO ram errors. If they pass with the proper timings and voltage as AJ suggested, then all is good. Make sure to set the ram speed properly as well, as sometimes the auto dividers set by the ram detection throw things horribly off. A good way to check your current ram settings quickly is with cpu-z. http://www.cpuid.com/cpuz.php The main thing you are concerned about is the ram megahertz. If you bought 667 ram at 4-4-4-12, and your ram megahertz is at 350, then that could be part of your problem (350x2 = 700 > 667). I ran into the exact same problem with my conroe build, as the ram divider for 667 actually changed the FSB/DDR2 settings to heavily overclock the ram...it wasn't until I set the divider back to 533 that things worked properly. Usually ram will allow you to run a bit out of spec, but usually not WAY out of spec. (my default divider had my 667 3-3-3-10 mushkin DDR2 at 804 megahertz!)

Wayne Harney Posted October 5, 2006 Author Share Posted October 5, 2006 Thanks for the cpu-z link Greg. Looks like it is running properly at 266mhz 1.8v 4-4-4-12 dual channel etc. as speced by corsair. Fran, viz2007 isn't causing the memtest fail. It's just not crashing with viz4 (still failing memtest) After further looking into it, it seems that viz2007 has a problem with vray proxies displayed in bounding box mode. I changed them to preview mode and it's running stable in viz2007... so far. Tried this on another machine with the same results. Still don't know what to do with the memory that is failing memtest and giving me an error in the vray feedback window but the system is running ok now.

Greg Hess Posted October 5, 2006 Share Posted October 5, 2006 Hey Wayne, It does look like its running at spec. What voltage are you supplying the ram with? It's usually 1.9 or 2.1v that's required. (Using the default vdimm might not be sufficent). Something you could try (to see if the memtest passes) is setting the latencies to 5-5-5-15 and the vdimm to 1.9. Memtest failing means you'll get erratic errors anytime the system is suitably stressed. Usually results in odd pauses, or things jerking a bit, and sometimes a full system crash.

Wayne Harney Posted October 5, 2006 Author Share Posted October 5, 2006 Thanks again Greg. The voltage is speced at 1.8 but I tried 1.9, 2.0 ,& 2.1. Also 5-5-5-15. Still failing memtest. I'll have to see if mwave will let me exchange for some twinx modules. Link to comment Share on other sites More sharing options...
Greg Hess Posted October 6, 2006 Share Posted October 6, 2006 Ug...sorry wayne...that really sucks. Not really much else you can do at this point. Link to comment Share on other sites More sharing options...
Wayne Harney Posted October 9, 2006 Author Share Posted October 9, 2006 FYI mwave is going to let me exchange for some twinx modules. Thumbs up for them! Link to comment Share on other sites More sharing options...
