TyR Posted October 9, 2007 Share Posted October 9, 2007 I just received all my parts to build my new system yesterday. I have not yet had a chance to try and get the 1066 MHz going with this memory, but I have encountered something that seems odd. When I load windows I see that I have 2048MB of memory, as expected. However during my multiple reboots, I noticed the post memory results being about 1k less as good than total. I just downloaded and setup my memory test (which is running at home right now) and it tells me I have a total of 2047 mb. I have not seen the results yet, but am wondering if this is enough to say there is definitely a problem or not. I will update this post as soon as I can get the results. What I am really wondering are a few questions. If there is a problem with the memory, is the 1kb shortage something I can live with or will it lead to bigger problems down the road? Could I have something mis configured in the bios that would make not all of the memory visible? Should I be running these as dual channel instead of single channel and could having them in single channel now cause a problem? If I do have to send back the memory and it is only one stick that is faulty, can I send only it so I can still at least be frustrated at the undoubtedly slowness that will be Vista under 1GB of memory? Thanks for any help on this issue. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted October 9, 2007 Corsair Employees Share Posted October 9, 2007 What I am really wondering are a few questions. If there is a problem with the memory, is the 1kb shortage something I can live with or will it lead to bigger problems down the road? A: That is normal for that MB, its the way the BIOS shows and reports the memory. Should I be running these as dual channel instead of single channel and could having them in single channel now cause a problem? A: Dual Channel of course, if you have Two modules and a 1066 FSB CPU or faster just load setup defaults and set the Dim Voltage to 2.2 volts and then set SLI Ready Memory to CPU 0% and set the CPC/CR to 2T, then test with http://www.memtest.org! In addition, with some MB's (Mostly ASUS) you have to disable legacy USB in the bios when running any memory test. Are you getting errors with the tested settings set and Legacy USB disabled?

TyR Posted October 9, 2007 Author Share Posted October 9, 2007 Ok, so the report of showing 1kb or so less than the total reported is not a problem. I just don't recall seeing that like that before, but I think my last bios only measured in megabytes where this one is done in bytes I think. As far as the usb legacy, I think it is still set as enabled. However I have this running from a cd, so would that still cause an issue? Last I heard (I decided to phone home and get a report) the test I am currently running is at 18% pass with no errors. I will definitely get those switched to dual channels. It has been so long since I have had less than 4 that I have not had to even think about dual channel in a long time. I am guessing that is why I crashed when I had the sli ready memory enabled before. I do not actually have to be running with two video cards in sli yet to have that option enabled though right? It is more of an option to get my memory above the default speed? Link to comment Share on other sites More sharing options...
TyR Posted October 9, 2007 Author Share Posted October 9, 2007 Update time. When I got home my memory test had completed its pass and there were no errors found. I then moved the memory into dual channel positions and used tried out the suggested settings. Unfortunately, I could not even get post to complete. Information on my screen would be displayed and then just stop halfway through a line. One time it even changed color. I had to do a bios reset on the board and then deal with vista not loading right (thinking this is either a power config issue or something with the video drivers getting messed up when windows does not load). Could there be some other setting in my bios that is not configured correctly also? Unfortunately this is first system I have put together with a pci-e card so there are quite a few new settings as well as I have never dealt much with memory settings. I have tried to find a site that actually has good detailed information on what each bios setting is for, but I have not had a whole lot of luck with that yet.

Corsair Employees RAM GUY Posted October 10, 2007 Corsair Employees Share Posted October 10, 2007 What is the complete system configuration? And if the modules will run and pass http://www.memtest.org one at a time but the system will not post with 2 modules in dual channel that would suggest a BIOS or MB problem and I would contact the MB Maker.

TyR Posted October 10, 2007 Author Share Posted October 10, 2007 It does actually boot up with dual channel, but not with the bios settings suggested earlier. If I go back to the default ones it loads fine (except that annoying issue with vista, but that is taken care of after some fun in safe mode). As far as settings I can give you what cpu-z tells me. If you need something not mentioned here let me know and I will dig it up. Thanks again for the help.

TyR Posted October 10, 2007 Author Share Posted October 10, 2007 Yeah I need to try that again. The time I did try to set it to 2.2 manually is when I also set the sli memory enabled option (which I think is what is causing me trouble). To narrow down my problems I reinstalled xp last night. At least with that I know where everything is I need to set and I do not have to worry about conflicts of drivers with old hardware or even new to a certain degree. Should I also explicitly set the settings that I are listed for the memory at 1066MHz on the product spec page or is that something that just changing the voltage will work out on its own? This is what I get for spending all of these years slacking on doing overclocking and messing with all of those settings. Link to comment Share on other sites More sharing options...

This is what I get for spending all of these years slacking on doing overclocking and messing with all of those settings. The latencies look good to me but, you can set them manually if you like. However, I'd suggest that you not use the SLI Ready memory setting and that you set the voltage manually to 2.2v. Link to comment Share on other sites More sharing options...
TyR Posted October 11, 2007 Author Share Posted October 11, 2007 I set the voltage to be 2.2 and the cycle to be 15. I am still at 800 MHz, so do I need to adjust the multiplier to up this? I am going to run the memtest while I sleep tonight and see how that goes with these new settings so far. Link to comment Share on other sites More sharing options...

I am going to run the memtest while I sleep tonight and see how that goes with these new settings so far. Set the speed manually as Derek noted as well as the latencies and the voltage. For Memtest, be sure to disable Legacy USB Support as it has a conflict with the ASUS boards. Link to comment Share on other sites More sharing options...
TyR Posted October 11, 2007 Author Share Posted October 11, 2007 I tested with what I had set up last night (forgot to disable legacy usb), and everything came out ok. One thing I noticed this morning is in the voltage monitor it showed the memory voltage to be 2.25. Is that extra 0.05 something I should worry about and try to correct by adjusting the voltage to be 2.15 to hit exactly 2.2? I will look for the 533MHz setting later today and test again with that. Everything else was correct with the auto setting already, so I did not actually set those. Link to comment Share on other sites More sharing options...
Yellowbeard Posted October 11, 2007 Share Posted October 11, 2007 The .05v is not a problem. However, if you do decide to test it and you are stable at 2.15v, it is fine to run it at the lowest stable voltage you can use. Less V = less heat.

TyR Posted October 11, 2007 Author Share Posted October 11, 2007 I think it was set to run at 1.8v with the auto and everything seemed to run fine. I am guessing that could change when I set the frequency to 533 instead of its default of 400 MHz though. When running a memtest at the new frequency, will one pass through be enough to help me pick up any instability or will that just be something I notice in windows with crashing and locking up?

Personally I use 3-5 passes if I am simply testing for stability. However, if I am troubleshooting an issue where there has been lots of crashes I do between 5-10 just to be more thorough.

TyR Posted October 11, 2007 Author Share Posted October 11, 2007 Sounds like a plan, I just let it go while I am sleeping usually and check the results in the morning. I will try and get this set and tested later tonight when I get a chance. Thanks again for the help and I will post an update when I have something.

TyR Posted October 12, 2007 Author Share Posted October 12, 2007 Unfortunately I did not have much of a chance to test this last night. I did try to set this to 1066MHz by using a 1:1 ratio, but I appeared to have some trouble booting up. I may need to set some other options in the bios still, so I am not sure if that could be causing issues as well. Lots of new settings with little to no information about them in the bios or manual, so I will need to hit google this weekend. When I do switch to manual settings from auto so that I can change the ratio and thus get 1066 MHz, does this behave as I would expect? That is will all of the default settings from auto be kept or will the bios do something odd and make me have to actually modify other things that may be set to an incompatible setting in the process?

TyR Posted October 13, 2007 Author Share Posted October 13, 2007 How long does the RMA process normally take? It could be a pretty big inconvenience at times since I do some of my work on here and I have no other system that is currently functional. I would like to keep trying with what I have now since it is probably my ignorance with these settings causing a problem. That is assuming you are able to put up with my random questions. I did try some more settings a little bit ago and was able to load windows for a brief time before I blue screened. I tried some more settings but nothing was stable. Can I tell if a voltage or any other setting is off by a value being too high or too low by any certain way a system will crash? Link to comment Share on other sites More sharing options...
