Arkengel78 Posted January 7, 2009 Share Posted January 7, 2009 I'm bringing this thread to light again as i am going back to square one again and has so far been a week with 2 correspondence to tech support and no reply as yet....tech support express??....little dissappointing about the express part. But basically i have 2 X 2GB 1600C7DHXIN ram in my system, an Asus P5E3 Premium Wi/Fi motherboard with an Intel Q9650 3.0Ghz CPU. To date i have been unsuccessful in getting this ram operating at it's stock 1600 speed and timings of 7-7-7-20 and maintain system stability. Currently i have it downgraded to 1333 speed with timings of 9-9-9-24 and whilst all good and system stability is achieved that isnt exactely why i purchased 1600mhz ram. Utilising other forums as well as this one and trying to emulate identical/similar system bios settings still hasnt netted me much success. I have run memtest software on the ram and it appears fine with no physical faults with it other than it not running as it should. I have more or less gathered that NB and ram voltage are the key to the stability? ram voltage i had always set, written on the ram, to 1.9v in the bios with NB voltage i have been attempting numerous other values in the 1.40-1.55v range. I have been using linpack testing as the guage for system stability. in most instances i would make a setting and run linpack and it would pass without fail however overnight or after a non set amount of time i would run the same test and failures would occur under the exact same settings. 99% of the time linpack failures occur when system is under 100% memory load. under medium or low stresses would past stability tests. Is that a clue somehow, would tweaking something in particular assist the stability under max stress. at the moment, going into the weekend, going to try again from square one with bios settings but really need a hand with this and some direction as to what to play with more to get this ram running the way it should in this system. thanks a bunch Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted January 7, 2009 Corsair Employees Share Posted January 7, 2009 We are sorry if you had slow results from TSX as it was likely due to the holidays. Have you tried using the XMP profile for the memory? Also, please try the most recent version of Memtest as I am not familiar with the Linpack testing. http://www.memtest.org You can Memtest either with the XMP profile or by setting the timings and voltage manually.

Arkengel78 Posted January 8, 2009 Author Share Posted January 8, 2009 thanks for the reply to answer your questions. yes i have used both XMP profiles and manually entered the speeds into the bios. have utilised memtest for both with no hardware issues being detected. however when attempting to load windows vista 64 bit with the xmp it would load but BSOD, dump and reboot the system. manual input faired a little better and windows would load however using linpack (IntelBurn Test v1.9) on full stress it would report an unstable system and whilst playing games for example would be unpredictable, freeze up etc motherboard bios is current, revision 0605 as well as all other drivers in the system. I'm currently attempting to tweak the bios again to try to achieve stable settings. any thoughts or ideas that might assist me further? Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted January 8, 2009 Corsair Employees Share Posted January 8, 2009 Install Vista with only 1 module install. Do ALL updates including SP-1 and then install the 2nd module. Link to comment Share on other sites More sharing options...
Wired Posted January 8, 2009 Share Posted January 8, 2009 Agreed. Did the same thing 2 weeks ago and it worked flawlessly. There's multiple stories out there of people installing Vista with more than one stick and having issues. Not sure if it's a memory size issue or multiple stick issue.

Vista pre SP-1 needs a patch to operate with 4GB+ of memory. In most cases, installing with 1 module is a workaround and gets the user to a point where they can install the patch or SP-1 which has the patch embedded.

Arkengel78 Posted January 9, 2009 Author Share Posted January 9, 2009 i already have service pack one installed for this system and its never been an issue from what i recall, even without it in recognising that i have 4GB ram in the system. are you asking me to do a fresh install of vista 64 again with the one stick with all the latest updates and then putting in the other stick? how would you like me to proceed Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted January 9, 2009 Corsair Employees Share Posted January 9, 2009 Try manually applying this patch: Vista Patch 929777. If that fails, you may want to try a clean install with 1 module, do all the manual updates, and then reinstall the second module. Link to comment Share on other sites More sharing options...
Arkengel78 Posted January 9, 2009 Author Share Posted January 9, 2009 ok, ill try anything at this stage, see how i go Link to comment Share on other sites More sharing options...
Arkengel78 Posted January 11, 2009 Author Share Posted January 11, 2009 ok, the results are in and...no change. apart from a nice clean install with vista 64, nice and clean an tidy tho i mite add before i did the reinstall i tried both modules individually with XMP profile and manually entering settings to bios with no stability success. did the fresh install of the operating system and made all the updates to date still with the single ram stick in. did all of that and tested each module by itself with the two different settings and again the same problems. adding the other module with it running in dual channel did not work. As before the operating system has no problem in id'ing that i have 4gb ram in the system but having it running at the correct speed and having the system run stable is the problem. tech support has responded to me and what it apparently boils down to is that my CPU is the problem. it runs stock at 1333 speed, whilst the ram is 1600 and the board itself can support 1600. they told me i have to overclock the cpu in order to match the board/ram speed. at the moment though as a 3.0ghz cpu it runs at 3.60. so the system is already automatically overclocking it as far as i can gather. and if my math is right then it is matching the board's fsb speed, 1600, so in theory it should not be having any issues...though it is. feel i need to go and do 4 years years of university again just to get this to work :P Link to comment Share on other sites More sharing options...

Insert a single DRAM module in the Slot 2 (From the CPU) and boot to the memtest CD allowing for two full passes. Shut the system down and remove the first stick. Insert the second stick in slot four (Closest to the end of the motherboard). Boot to the Memtest CD and allow for two full passes. Finally, shut the system down and insert the first stick back into slot 2 and boot to the Memtest CD. Then, if stable, enter Windows and post your CPU-z CPU/Memory and SPD tabs in screenshots. Post all two SPD modules from the drop down menu in the SPD tab. Link to comment Share on other sites More sharing options...
