Hey guys,I've recently learned that my RAM/Memory may be unstable, might have the wrong voltage setting, or might not be compatible with my MOBO. I've had a lot of FSX CTD's from dll's that crash usually when memory is faulty. In my attempt to make sure my 3 sticks of ram were were okay, I went around google and saw a lot of stuff that made no sense to me. I was wondering if anyone could help me through this. What I'm trying to do is get my 3x Channel DDR3 1600 Ram to work with my Gigabyte GA-X58A-UD3R mobo as stable as possible, which it should do by default because it is compatible. That said, I've been having a difficult time figuring out exactly WHAT I should be doing to make it stable, if it isn't already. I did note that XMP was off in my BIOS.I was able to learn that my RAM currently runs at:Slot # | JADEC#1 | JADEC#2 | XMP-1600Slot 1 | 592Mhz | 666Mhz | 800MhzSlot 3 | 592Mhz | 666Mhz | 800MhzSlot 5 | 592Mhz | 666Mhz | 800MhzVoltage | 1.5v | 1.5v | 1.65vI learned that I *should* be at a factory default of SPD Speed 1333Mhz, I guess, with something at 9-9-9-24, but I have no idea what those are. Also, in my BIOS it does say my current memory frequency is 1066Mhz, which doesn't sound right... As far as my system goes, I'm running:OS: Windows 7 64 bit Home PremiumMemory: Corsair XMS3 6GB (3x2GB) DDR3 SDRAM 1600 (PC3 12800)Mobo: Gigabyte GA-X58A-UD3R LGA 1366 Intel X58 SATA 6GB/s USB 3.0 ATX Intel MotherboardCPU: Intel Core i7-950 Bloomfield 3.06Ghz LGA 1366 Quad-Core ProcessorGPU: Nvidia 9800 GT Graphics CardThank's for reading. If anyone could point me in the right direction here on how to make sure my RAM is stable and at its right settings I'd much appreciate it!

Your ram runs at 1600HMz, 1.65v at 9-9-9-24 timings.Your ram speed is tied to your BCLK setting in BIOS.In BIOS you can change your ram speed, voltage and timings.For starters look in your BIOS and see what your ram is set to, if you need to look at your motherboard manual to see where in BIOS you need to go look. I have never OC'ed a Gigabyte MB so I am not familar with their terms. The first thing you can do is set the ram voltage to 1.65 or 1.66, the setting will probably be called DRAM Voltage. Next set your timings to 9-9-9-24.If you are lost post a link to your motherboard manual so we can tell you where to go in your BIOS to make the changes.

http://download.giga...x58a-ud3r_e.pdf <- Manual for my Motherboard.Now I've heard that my RAM voltage depends on my CPU speed and my FSB speed, so setting it to 1.65v would depend on those speeds. Currently, I haven't OC'd my i7-950 so it should still be at 3.06Ghz. If that's the case, should I still boost my RAM speed or would I run the risk of making things more unstable?Honestly, I'm a pretty bad novice at this, and I have no idea what I'm doing.

Ken,NickN is an acknowledged expert in this area. He helped me get my system running top notch. Take a look here: http://www.simforums.com/forums/bios-setup_topic38913_post228574.html?KW=i7+950+overclock#228574

Before you overclock you should get everything running stable at default. If you start overclocking with an unstable system you will just add more problems to your current problems.Ram voltage has nothing to do with CPU/FSB speed on a i7 9XX setup when set manually. I have no clue what the auto setting may do.This link will show you the relationship of BCLK, CPU multi, QPI multi, Uncore multi and Mem multi and the affect this has on the various frequency settings.http://icrontic.com/...s/nehalem-calc/Here are a couple of really good i7 9XX overclock guides you can read that will explain all of this even more.http://www.clunk.org...-beginners.htmlhttp://vip.asus.com/...SLanguage=en-usGo look on page 39 of your MB manual. If your system clock is at default then CPU Frequency should show as 3.06GHz (133*23). If it does not then you are not at default and you should reset your BIOS to default until you get your stability problems fixed. Note that after you reset you will need to redo your boot priority, if any of your sata ports were set to AHCI or RAID you will need to set them back to what they were. Before you reset it would really be a good idea to take pictures of all your BIOS screens so you have something to reference after you reset. You will need a laptop or something to look at the pictues if you took digital pictures.After you confirm you are at default and the PC is booting into Windows then go back into BIOS and go back to page 39 of the manual.Change DRAM Timing Selectable to ExpertUnder >>>> Channel AChange CAS Latency Time from Auto to 9Change tRCE from Auto to 9Change tRP from Auto to 9Change tRAS from Auto to 24Change Command Rate to 1T or 1N or just plain 1, whatever option is there.Do the same thing under >>>Channel B and >>>>Channel CJump to page 47 and change DRAM Voltage to 1.65. If it will not let you use 1.65 then use the the voltage as close to 1.65 as you can get. If you use 1.66 and you get somekind of warning about Intel says this may damage your blah, blah, blah ignore it and set it to 1.66 anyway.Save and exit from BIOSNote that with all of the above your ram freq is still only 1067MHz or something close to that. Once you determine the above is stable then we can make some more changes.To test for stability download OCCT, RealTemp and SpeedFan.http://www.ocbase.co...ex.php?Downloadhttp://www.techpowerup.com/realtemp/http://www.almico.com/sfdownload.phpRun OCCT on the one hour CPU auto test only. Monitor your core temps with RealTemp and your core temps should not go over 80C. If they do shut OCCT down immediately.If you pass the OCCT test download SuperPI and run that a couple of times at the 32M setting.http://www.techpower...I_Mod_v1.5.htmlLet me know how it goes.If you want to read up on i7 9XX overclocking for FSX, like Superglide17 said NickN is a great source. You can go to the simforums and just do a seach by NickN, 920 overclock, 950 overclock, etc. and a whole bunch of threads should popup.

Also you need to download BlueScreenView so you can have a record of any BSOD codes you get while stress testing.http://www.nirsoft.n...creen_view.htmlYou could also run OCCT and SuperPI before you change anything in BIOS just to see if they pass or not.
