Xms2-8500c5d & Ga X38 Ds5


Recommended Posts

HI there, I'm running a GA-X38-DS5 - with a QUAD Core 6700 - an HD3870 - and a Seagate 320g, I built my comp and did a few test runs, came to a few issues regarding bios, tried to update it, but kept bringing up Award Bootblock v1.0 etc... trying to scan for image bios or recover from image bios, very annoying.


I never got that to work properly, but anyway in the end I'm back to the default Bios version from the Dual bios recovery. I have 4 sticks of the CM2X1024 - 8500C5D they picked up fine and didn't seem to have any issues. Until I got blue screens of Memory management and Memory leaks.


Checked the bios and I've done a bit of looking around this forum looking for answers, the bios with load safe settings on, puts the timings @ 5-5-5-18 :bigeyes: obviously I found the timings on this forum and have changed them manually, though the only thing I changed was the Precharge Delay (tRAS): from 18 to 15. Should I have changed other things ?


I'm normally the type of guy that work with computer @ stock settings, don't want to temp the devil by changing too many things. But this is a big issue as my computer right now doesn't seem to be stable. I'm also wondering if the Motherboard is not faulty. I mean it used to loop restart every 5 secs trying to recover the Bios.


I also know that when running XP I won't get the full 4 gig, but just 3.5g will that affect anything? I was able to boot into windows, and it did tell me that I was running 3.5 gig and i'm fine with that, until I move to Vista.


I know this issue can be a bit all over the place, but the one thing I did find wrong was the ram so here I am making a post about it.


I am now formating hopping not to get a BSOD also I only have 3 stick in there at the moment, to test things out, don't know if the changing of the Precharge Delay fixed my issues yet.


I shall wait till it's formated and chuck in the fourth stick and see how it goes.


Any suggestions or different views are welcomed :)

Cheers guys

hear me out, lol - I installed Windows and booted into windows with the settings @ 5-5-5-15 with 3 sticks in Flex mode, I then put the fourth stick in, tried another format for the hell of it, and it won't do it - took the fourth stick out, and its working again. WTH ? I am astonished :P

Here is one test, 3 sticks running in flex mode -



Also here is what I get randomly when i restart the comp lol


- i just got it when I shutdown the comp after the mem test to take one stick out, anyway i'm doing the test for each stick now, 1 at a time, I shall post the results for each.


I'm starting to think that my motherboard is the problem for everything, I mean I heard of others having similar issues on the X38-DQ6 - been looking for other peeps with my MB but didn't find much.

Alright - I tested each stick, in the first slot :) they all seem fine, they ran for 2+ hours each, now I'm testing the other slots - then i'll go and test for dual channels see how that goes... will keep you guys posted, but that what i've seen, the RAM is clear - i think its the bloody board -

Is there any chance that the RAM is not compatible with my MotherBoard ?


Intel CORE2QUAD Q6700/2.66GHz/2x4MB/1066FSB/LGA775/QUAD CORE

Gigabyte GA-X38-DS5 X38, 1600MHz FSB, DDR2-1066MHz, 2xPCIE

Corsair TWIN2X2048-8500C5D

Sapphire HD3870 512M GDDr4 PCIEx16 Dual DVI

Corsair TX-750 750W ATX Power


those are my specs

Your DRAM is compatible with that motherboard according to the Gigabyte QVL.




It shows CM2X1024-8500C5 as compatible and those modules are the same as your modules.


Is the recovery happening when you insert DRAM in another slot? You tested slot one to work so I wonder if you are having issues with a slot?




Keep in mind that with four DRAM slots populated, you will very likely need to drop the bandwidth to 800Mhz to achieve stability. Please read this previous link regarding your situation.

Well I tested all sticks in one slot individually worked fine, then I took 1 of the stick and then did the tests on the other slots - I got to the four slot and then it started restarting itself randomly and funny I didn't change anything for like the past 8 hours of testing for the previous ram, I thought maybe it was a bad slot, but I put the ram stick back to the other slots, computer still restarted itself - I thought it might be a short, unplugged everything, took everything out, put everything on a table and assemble it there and test it further, still restarting randomly - I'm out of luck, I'm taking it to my supplier today for further testing -


Thanks for the heads up guys, so sad I am after spending $3200 on friday to not being able to play with it and spent the entire week-end testing :'( oh well I can BEAT this :D


will keep you guys updated

Shut the system down. Insert two DRAM sticks into the first and third slots. Press the "0/Insert" key on the keyboard number pad and while pressing it down, push the computer start button. Keep the 0/Insert key pressed while the system starts up and when you hear the beep, press the "Delete" key. Let go of the 0/Insert key and allow the system to enter the Setup - BIOS. Load setup defaults. Set your Vdimm (Dimm OverVoltage Control = +.3V) and save settings. Restart and re-enter your BIOS. On the main BIOS screen press Ctrl + F1. You will see the screen flicker. Next select the MB Intelligent Tweaker option.

Test your system with Memtest. If clean, then shut the system down and remove those two sticks. Insert the other two sticks in their place and retest. If they come up clean, then insert the second set in the second and fourth slot. Retest with memtest.
