JackRabbitEwing Posted February 28, 2007 Share Posted February 28, 2007 Hello, I built a system about 3 weeks ago, strictly for playing BattleField 2. I got the usual ASUS P5L-MX, Intel E6600, great memory from Corsair!, three Western Digital Raptor drives (RAID 0 boot and a spare for the temp drives), eVGA NVIDIA 8800 GTS. Everything was put together on a static mat on a bench and I was wearing a static strap. Flashed the BIOS, everything ran great. Ocassionally upon exiting from BF2, I would get sound 'glitches', and even less often a lockup. Well tonight, 3 weeks after my initial build, when I exited BF2, the screen went blank. I pushed the reset button, no response. Turned off the power supply, waited a couple of minutes, turned it on.... no response. Opened the case and substituted another video card. No response. Took out both sticks of the Corsair memory, put one stick in of OCZ PC5400. It started booting. Turned it off, put in ONE stick of the Corsair. Nothing. I tried each stick of Corsair in each slot, no response. I can't believe it! I have NEVER had memory go bad or not work. Right now my computer is running fine (but slower) on the PC 5400 ram. I tried resetting CMOS and still the Corsair memory gave me no response. I do NOT overclock, change any voltage or anything on my PC's. (I have 10 in the house) and I can't believe that both have went dead at once. Maybe one was marginal and then the other one gave out, who knows. Any suggestions? To verify my system, I MIGHT be willing to purchase 2 more GIG of PC8500 if I can find it locally, just to verify everything works the way it did before. Obviously I would rather NOT do this, as it will be around $400 out of my pocket. I love Corsair memory, and I love the heat fins and looks of these modules. HELP!

Corsair Employee RAM GUY Posted February 28, 2007 Corsair Employee Share Posted February 28, 2007 Can you flash back to the previous Bios on the MB and see if it will post with our modules? If you can get it to post please run CPU-Z and tell me what is says about the modules. Link to comment Share on other sites More sharing options...
JackRabbitEwing Posted March 1, 2007 Author Share Posted March 1, 2007 Unfortunately, no. When I upgraded it warned me that it could not 'go back' to the previous version. I reported the motherboard wrong in my original post... it is really an ASUS P5B-Deluxe. But the ram worked fine for 3 weeks. Nothing changed since day 1 and I have not even had the cover off the computer till last night. Here is a dump of CPU-Z before the bios update. The modules reported as PC 6400 (I know this is it because I do not own a pair of Corsair PC-6400, and the PC-8500 is the only memory I had in this motherboard from the start) I may be able to put it in another motherboard and see if it will post, but I don't have another 1066 FSB motherboard, nor CPU to go in it if I did..

Corsair Employee RAM GUY Posted March 1, 2007 Corsair Employee Share Posted March 1, 2007 I would try and reset the bios with the CLRTC jumper with the power and battery removed and then test the modules one at a time and Please Change ‘Write to Precharge delay’ in the BIOS (same page as for latencies) from default 10 to 15 and then test the modules again with the Voltage set to 2.o Volts and the tested settings set manually! Then test with http://www.memtest.org to be sure! In addition, with this MB you have to disable legacy USB in the bios when running any memory test.

JackRabbitEwing Posted March 3, 2007 Author Share Posted March 3, 2007 OK. I tried resetting CMOS again, no go. I put my slow ram in, and in the bios changed the setting you suggested from 10 to 15 and the voltage to 2.0. Saved settings. Put 1 stick of of the Corsair in.... it posted, but showed a value of 774 Meg, which is wrong. Changed the overall speed of the CPU from a multiplier of 266 to 265, so the ram is running at 1030 or so. Put in both sticks, it posted and booted into windows, showing 2048 MEG, which is correct. I would guess that the stick that only shows 774 MEG at the actual 1066 settings is suspect. What I would like to do is RMA both sticks and get a pair of fresh ones. Can I get an RMA number. I never got memtest to work on my machine. Either floppy or CD booted into a black screen with hex scrolling by, but no usable information.....

Corsair Employee RAM GUY Posted March 5, 2007 Corsair Employee Share Posted March 5, 2007 The MB you have listed does it have the option to set the memory voltage to 2.2 Volts? And what are the exact settings you have set? Link to comment Share on other sites More sharing options...
JackRabbitEwing Posted March 6, 2007 Author Share Posted March 6, 2007 Yes, my motherboard will support voltage from 1.80 through 2.50 in .05 Volt steps. The exact setting are: Voltage 2.0 (as per your post) CAS Latency 5 RAS to CAS Delay 6 RAS Precharge 6 RAS Activate to Precharge 15 Write Recovery 6 TFRC 42 TRRD 10 Rank Write to Read Delay 10 Read to Precharge Delay 10 Write to Precharge Delay 15 (as per your post) I believe it would be in both our interests if I got an RMA number. I don't feel that I should go through hoops for days trying different things to see if it works or not. Please remember, THESE MODULES WORKED GREAT for about 3 weeks. I did NOT change any parameter in BIOS during that time, nor did I open the case to move/install/remove any cards, disks or anything. I really want this resolved by Friday, so I have time to go out and purchase another set of memory. Because these modules worked great out of the box, and now they work if I slow the system down some, I think the odds are great it is the either the memory or motherboard, and probably not settings, assuming the SPD stuff is corrrect.

Corsair Employee RAM GUY Posted March 6, 2007 Corsair Employee Share Posted March 6, 2007 First thing, I have no problem replacing the modules for you, but what you have posted would suggest some other problem, and I would suggest replacing the MB based on what you have posted especially if this happens a third time. Also the Intel I965 chipset will not run 1066 Memory by default and over clocked with a MB model that does over clock well like the ASUS P5B Deluxe will top out about 920-1030 Mhz. If you want to try replacing them, please use the On Line RMA Request Form and we will be happy to replace them or it. Link to comment Share on other sites More sharing options...
JackRabbitEwing Posted March 6, 2007 Author Share Posted March 6, 2007 I don't mind buying another motherboard. I don't want something on the screaming edge.... Just a fast, stable system. Do you have any motherboards that are compatible? Or a list of 'approved' boards for 1066 FSB? Thanks. Link to comment Share on other sites More sharing options...
Corsair Employee RAM GUY Posted March 6, 2007 Corsair Employee Share Posted March 6, 2007 Please look up the module on Corsair Labs Performance Reports for a list of MB that we used and tested with these modules. But almost any of the AM2 MB will support these modules. Link to comment Share on other sites More sharing options...
JackRabbitEwing Posted March 7, 2007 Author Share Posted March 7, 2007 Nice reference area I have not seen before. However, when I narrow down the search for the memory I have (PC8500-C2D), the exact motherboard I have is listed in Corsair Labs Performance Report #55369 - 1/9/2007, with no notes saying there may be an issue with this motherboard/chipset combination. Now that I know the 965 chip set is not a 'true' 1066, I will look for another motherboard this week. Thanks. I will hold off on the rma till I swap motherboards.

JackRabbitEwing Posted March 16, 2007 Author Share Posted March 16, 2007 Update: Purchased ASUS Stryker Extreme. Same issues. Wont boot/post after setting speed to PC8500. Boots at PC6400, but has memory errors, so I am pretty sure it is a ram module. I borrowed (had to promise my firstborn) a mates PC8500 Dominator modules. Work great, even at PC8500. Man, what a machine! Sent RMA email today! Thanks for your help ramguy! Link to comment Share on other sites More sharing options...
Corsair Employee RAM GUY Posted March 16, 2007 Corsair Employee Share Posted March 16, 2007 Are you setting the memory Voltage to 2.2 Volts and did you update the Bios? Just get the latest bios and then load setup defaults and set the memory voltage and set SLI ready memory to CPU Max then Disable legacy USB and exit saving changes and test with http://www.memtest.org.
