snowdrift Posted December 27, 2006 Share Posted December 27, 2006 Hello, all. This is my first posting here. After reading through several posts here and Googling, I have made the plunge and am replacing my Crucial "10th Anniversary" DDR2 DIMMs I got in late November from newegg.com due to ongoing MEM86+ failures. I have decided to go with Corsair based on largely positive reviews and on the support of this board and have selected TWIN2X2048-6400C4. I hope I am not disappointed and am glad I am getting the $40 rebate that's going on right now on the RAM from newegg. I surely hope my memory errors go away with these new sticks.

DerekT Posted December 27, 2006 Share Posted December 27, 2006 Hi Snowdrift, I, like you, came here to deal with system issues. I came away with my problems cleared up. This has happened a few times since and each time Corsair's help has been exemplary so I now come by to help myself. I have installed this ram on that motherboard on more than a few occasions with no problems. You will have to enter the BIOS to set the DRAM correctly but we can easily help you with that. I also totally understand you wanting to have a system working without "issues". :D: Link to comment Share on other sites More sharing options...
snowdrift Posted December 27, 2006 Author Share Posted December 27, 2006 Well, I found the specs somewhere else on these Corsair DIMMs. I just need them to come in from newegg now! ;-) I am so disappointed by the C R U C ! A L "10th Anniversary" sets I got. Everybody praised them, but one of them is bad and newegg.com is requiring both DIMMs back before I can get a refund. They are CAS3 but if you can't get them to pass MEM86+ then that's of little help. In a way, I guess, I hope it is those 6-week-old DIMMs that are screwy; otherwise, I will have to consider the mobo, which I would hate to go without and which is far more troublesome to return. When I did my last machine build 2-1/2 yrs. ago, things were so much simpler. Everything changes so fast, it's hard to keep up unless you're building all the time (which I guess is what the manufacturers must want). Here's hoping I get the new sets Friday! Otherwise, it's after the 1st. ;-) Link to comment Share on other sites More sharing options...

snowdrift Posted December 28, 2006 Author Share Posted December 28, 2006 Ram Guy, I plan on using the stock settings for the RAM I have ordered as outlined above (which should arrive tomorrow). Here is the thread with the specs (CAS4) I am going to use: http://www.houseofhelp.com/forums/showthread.php?p=272861#post272861 I have the exact same mobo and memory as outlined in this previous case from a couple of weeks back.

Corsair Employees RAM GUY Posted December 29, 2006 Corsair Employees Share Posted December 29, 2006 Please just use the settings in found in the link from my signature and you should be fine as long as you have a 1066 FSB CPU and this is for an ASUS P5B correct?

snowdrift Posted December 29, 2006 Author Share Posted December 29, 2006 Yes, Ram Guy. I am only running at stock (for now) at 1066MHz. It is an ASUS P5B Deluxe. I will report back once the RAM has been tested with Mem86+ for at least 12 hours. I should receive the two 1GB DIMMs today via UPS. Thank you.

LongView Posted December 29, 2006 Share Posted December 29, 2006 Well all of my components have now arrived so I'll be building over the weekend using many of the same parts detailed by snowdrift. Summary of main parts: ASUS P5B Deluxe Wi-Fi Intel Core Duo 2 E6600 (2.4ghz) VapoChill Micro Ultra Low Noise Corsair TWIN2X2048-6400C4 If I understand the motherboard manual correct the automatic configuration will set the memory at 667mhz and not the 800mhz that it can support. Should I be manually setting the memory to get it up to speed before I run MemTest (also planning on using Sandra burn-in wizard) or check the stability using all the default settings first? Looks like I have a steep learning curve ahead of me as the memory landscape has really changed since I first started building computers. Any tips and advice gratefully received.

snowdrift Posted December 29, 2006 Author Share Posted December 29, 2006 ... just got the new RAM in. Looks like default from the mobo is to treat it CAS5. I have the CAS4 specs from Ram Guy's footer attachment and am trying that next, followed by MEM86+. Later... Link to comment Share on other sites More sharing options...

LongView Posted December 29, 2006 Share Posted December 29, 2006 snowdrift: Hope you don't mind me joining in on your thread but I thought since we are using similar components it might be useful to use the same topic so that we can compare notes if needed. If you'd rather I posted under my own topic then please tell me. I have the basic components installed inside the Lexa (what a lovely case that is to work with and very quiet) along with a optical drive to boot off and run MemTest. So far I have updated to the latest BIOS and manually set the memory to DDR2-800 with 2.1volts and changed the memory timings. The only other change is to disable legacy USB support as recommended (good job I was able to get hold of an old non-USB keyboard :eek: ) Am onto the 2nd pass of Memtest now with no errors and 1 pass so will leave this running for a few more passes just to be sure. Shame that Memtest can't report on the chipset as it shows useful information when I run it on the P4C800-E Deluxe. Next step, assuming no MemTest errors, is to install XP Pro SP2 and Sandra 2007 to stress test the machine and check out my temps. Will keep you updated on my progress...

LongView Posted December 30, 2006 Share Posted December 30, 2006 A quick question: I'm now on the 6th pass (5 without error) and a single fail has just occurred -- is the odd error to be expected (after all this isn't ECC ram) or is that an indication that something isn't quite right? Test: 6 Pass: 5 Failing Address: 00021b27310 - 539.4MB Good: fffffeff Bad: bffffeff Err-Bits: 40000000 Count: 1 Will leave MemTest running over night to see what happens...

Corsair Employees RAM GUY Posted December 30, 2006 Corsair Employees Share Posted December 30, 2006 What do you have the bios settings set to for CPU and memory and Voltage? Link to comment Share on other sites More sharing options...
LongView Posted December 30, 2006 Share Posted December 30, 2006 I have only changed the frequency (DDR2-800), the voltage (2.1v) and the timings as per the Corsair recommendations: SDRAM CAS Latency: 4T SDRAM RAS to CAS Delay (tRCD): 4T SDRAM Row Precharge (tRP): 4T SDRAM Active to Precharge Delay (tRAS): 12T SDRAM Write Recovery Time: 5 Write to Precharge Delay: 15 FSB is 1064 (4x266) and multiplyer is locked (9x) to give a CPU speed of around 2.4ghz which is spec for an E6600. Another error has just appeared: Test: 2 Pass: 7 Failing Address: 00062f27310 - 1583.4MB Good: ffffffff Bad: bfffffff Err-Bits: 40000000 Count: 1 Personally 2 errors in over 3 hours of MemTest, and 7 passes, doesn't seem a big deal but then I accept that I'm not an expert. I would expect some errors or else there would be no need for ECC memory? Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted December 30, 2006 Corsair Employees Share Posted December 30, 2006 Did you disable Legacy USB in the bios when you ran http://www.memtest.org? If you did then let's try replacing your modules! 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...
LongView Posted December 30, 2006 Share Posted December 30, 2006 Yes I have disabled legacy USB support and I'm using a PS/2 keyboard. I'm in the UK so I can't use your RMA facility and at the moment replacing them seems a little extreme -- obviously I also accept that you know more about all this than I do. I'm going to leave MemTest running overnight as planned and then will continue on with running Sandra 2007 burn-in and also Prime95 too as that is good for showing up memory/CPU issues.

snowdrift Posted December 30, 2006 Author Share Posted December 30, 2006 ... sounds similar to what I was experiencing with the Cruc!al "10th Anniversary" DIMMs I RMA'd. I would get a single error in Test #7 (on each MEM86+ pass). The Corsair DIMMs I got to replace them are not giving me those problems. I let it run for a little over 3 hrs. tonight and no sign of a problem. I would not accept a single error in the test if I were you, or you will always second-guess it when you have later problems.

LongView Posted December 30, 2006 Share Posted December 30, 2006 The problem is that I have no direct access to Corsair here in the UK so my only other option is to return it to my supplier. I'm now on 4 errors and it has taken nearly 11 hours to encounter those so I very much doubt that any returns handler is likely to do anything more than a couple of passes of MemTest. If I leave MemTest running for a few hours on my existing P4C800-E Deluxe system, with TwinX2048-3200PT memory installed, I'll eventually get around the same number of memory errors and that system is rock solid under both XP and Vista. Please don't think that I'm not taking peoples advice seriously, I certainly am, but I think I need to do some Windows testing in order to have some proof. I'll take a picture of the MemTest screen as evidence. Thanks for all the input and I'll update once I have Prime95 installed and running. Link to comment Share on other sites More sharing options...
snowdrift Posted December 30, 2006 Author Share Posted December 30, 2006 I just finished running Memtest86+ for over 6 hours without a single error using the CAS4 spec for this RAM. I have boxed up the old DIMMs I am replacing and will be keeping this Corsair set. I am glad this problem seems resolved. Thank you, Ram Guy. One other thing, I did *not* disable legacy USB support under BIOS and the tests still worked without a hitch for me. I *did* set it to "Auto," which probably means it did in fact default to "off" since I do not use any USB 1.0 devices on this machine. Link to comment Share on other sites More sharing options...
LongView Posted December 30, 2006 Share Posted December 30, 2006 Looks like you have a great stable system there, am very envious! :): I now have XP SP2 installed with the latest Intel drivers for the ICH8R with the two drives installed as RAID0 with a single 150GB partition for now. I then installed the chipset INF file along with the sound, network, and graphics drivers. Prime95 has completed its benchmark and I'm now running the stress test so far without incident (1024K and 8K passed). Will let Prime95 run for a few hours before moving onto Sandra XI to do the burn-in wizard. Link to comment Share on other sites More sharing options...

I *did* set it to "Auto," which probably means it did in fact default to "off" since I do not use any USB 1.0 devices on this machine. The issue is with the BIOS/Legacy USB and Memtest. Not all BIOS's are effected by this bug but some are so it is far easier to just ask people to test with it disabled than try and decide which ones are effected and which ones are not effected.

LongView Posted December 31, 2006 Share Posted December 31, 2006 I left the Windows Memory Diagnostics running last night, something I'd downloaded from Microsoft.com a while back, and it did 128 passes overnight without a single error. I'm now running the program using the more thorough tests so will see how that goes. I let the thorough tests run three times and no errors occurred. I might well leave it running longer overnight tonight. Link to comment Share on other sites More sharing options...
snowdrift Posted December 31, 2006 Author Share Posted December 31, 2006 Although technically that program is still in beta, I know the one from M$ you're talking about, it does the same sorts of tests. It should be sound as a reference. I still think MemTest86+ v.1.65 (10/01/2005) is slightly more comprehensive, but either should work for you. Version 1.66 is imminent and is supposed to address a very few bugs and recognize more recent chipsets. Link to comment Share on other sites More sharing options...
