Jester13 Posted January 14, 2009 Share Posted January 14, 2009 I have tested all the ram and all the ports on the motherboard and they all seem to be in perfect working order. The problem comes in when I try to put in more then 4gb of ram.. The weird thing is, when I put in more then 4gb my VIDEO CARDS stop working.... Please help, I want to get more ram for some of the larger CAD drawings I do for work. Thanks for any help in advance. Link to comment Share on other sites More sharing options...
Wired Posted January 14, 2009 Share Posted January 14, 2009 What is the part # / version # of your memory? How To Read the Memory Label Please do NOT copy your specs from your profile into your posts, as it's already in the dropdown above all of your posts.

Jester13 Posted January 14, 2009 Author Share Posted January 14, 2009 Part number is CM2X2048-6400C5 Version number is ver3.1 Link to comment Share on other sites More sharing options...
Wired Posted January 14, 2009 Share Posted January 14, 2009 Just to be sure, all 4 sticks have the same version #? Was this bought as ONE QUAD kit, or TWO TWIN2X packs? Link to comment Share on other sites More sharing options...
Jester13 Posted January 14, 2009 Author Share Posted January 14, 2009 they were bought as 2 twin packs, but they have the same part/version numbers. I did jsut notice 2 sticks say 1.80v and 2 say 1.90v Link to comment Share on other sites More sharing options...

I would suggest that you contact the motherboard manufacturer and see if this is a known issue with them. Link to comment Share on other sites More sharing options...
Legend Posted January 14, 2009 Share Posted January 14, 2009 What driver version are you using for your 3870s? I'm aware that some users have experienced issues with this specific combination: 1. Catalyst 8.12 2. Vista 64 3. Crossfire 4. 4GB or more of RAM installed I would recommend trying Catalyst 8.11. Make sure you remove all the previous drivers and software for Catalyst.

I tried 2 earlier version of video drivers, and I also tried only having 1 video card in... same thing happens Link to comment Share on other sites More sharing options...
Jester13 Posted January 15, 2009 Author Share Posted January 15, 2009 Sorry to sound dumb, but would 2 sticks being 1.80v and 2 being 1.90v be the cause? If so, is there a way to change it? Link to comment Share on other sites More sharing options...
DerekT Posted January 15, 2009 Share Posted January 15, 2009 When you populate all four DRAM slots it is advised to drop the bandwidth and raise the NB/SPP voltage. So set the DRAM to 667Mhz and the NB/SPP Core +.2v. Download memtest from--->Here and extract the ISO image. Burn the ISO image to an CD-ROM disk. Download CPU-z from--> Here Enter your BIOS, load setup defaults and save setup defaults. Then set to these values: Advanced JumperFree Configuration AI Overclocking = Manual FSB Frequency = 200 PCI-e Frequency = 100MHz Processor Frequency Multiplier = Auto Processor Voltage = Auto Processor-NB Voltage = Auto CPU VDDA Voltage = Auto CPU-NB HT Link Speed = Auto DDR Voltage = 1.9v Northbridge Voltage = 1.45v Soutbridge Voltage = Auto Auto XPress = AutoCPU Tweak = Enabled Memory Configuration Bank Interleaving = Auto Channel Interleaving = Auto MemClk Tristate C3/ATLVID = Disabled Memory Hole Remapping = Enabled Unganged Mode Support = Disabled Power Down Enable = Disabled Read Delay = Auto DCQ Bypass Maximum = Auto DRAM Timing Mode Memclock Value = 667Mhz 2T Mode = Enabled DRAM Timing Mode = DCT 0 CAS Latency = 5 tRCD = 5 tRP = 5 tRAS = 15 All other settings are Auto SetRun Memtest for two full passes, then (If Stable), enter Windows and post screenshots of CPU-z's CPU, Memory and SPD tabs.

If so, is there a way to change it? The different voltage ratings mean that you are mixing 2 different revisions of memory which is not recommended. However, this cannot cause the video related problems you are seeing. Please let us know the results of your testing. Most likely this is going to be a BIOS related issue. Have you contacted the MOBO maker? Link to comment Share on other sites More sharing options...
Jester13 Posted July 3, 2009 Author Share Posted July 3, 2009 sorry for the extremely late reply, I was sent out of town for work for 6 months. When I go into the bios and go into JumperFree Configuration all I ge for options is this: AI Overclocking: Auto CPU-NB HT Link Speed: Auto **** Please key in voltage number directly! **** Processor Voltage: Auto Processor-NB Voltage: Auto ********************************************************** CPU VDDA Voltage: Auto CPU Tweak: Enable PLL1 Spread Spectrum: Disabled PLL2 Spread Spectrum: Disabled Link to comment Share on other sites More sharing options...
Jester13 Posted July 4, 2009 Author Share Posted July 4, 2009 And I also can't get into the bios with more then 4gb installed. When I boot with 8, I get no display on my monitors. Link to comment Share on other sites More sharing options...
Synthohol Posted July 5, 2009 Share Posted July 5, 2009 install vistas service pack http://www.microsoft.com/downloads/details.aspx?familyid=B0C7136D-5EBB-413B-89C9-CB3D06D12674&displaylang=en use 2 gig of ram and then after install try 4 then 8. the SP addresses some ram issues.

Corsair Employees RAM GUY Posted July 6, 2009 Corsair Employees Share Posted July 6, 2009 What are you setting the memory frequency and Voltage to? Should be DDR667 at 2.1 Volts for memory and +.2 Volts for NB/MCH/SPP Voltage. Link to comment Share on other sites More sharing options...
Jester13 Posted July 6, 2009 Author Share Posted July 6, 2009 What are you setting the memory frequency and Voltage to? Should be DDR667 at 2.1 Volts for memory and +.2 Volts for NB/MCH/SPP Voltage. I'm leaving everything at default. I don't even know where to go to change that information. My bios for some reason extremely lacks options... as per my post on the first page. And I can't see anything when I try all 4 sticks. My monitors just stay black. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted July 8, 2009 Corsair Employees Share Posted July 8, 2009 If you test the modules one at a time can you isolate a single module that may be causing the issues? If they all give you the same results, can you test a single module in each DIMM slot to make sure its not a slot on the board causing the problem? If you are having problems locating the settings in your BIOS you may want to consult the motherboards user manual or the motherboards support team. Some boards will make you set a setting like AI Overclocking to manual before they will give you the options to make the necessary adjustments.

Jester13 Posted July 10, 2009 Author Share Posted July 10, 2009 I have tested each module in each slot, and everything works. A-1 A-2 A-3 A-4 B-1 B-2 B-3 B-4 C-1 C-2 C-3 C-4 D-1 D-2 D-3 D-4 I will try the thing with my mother board's bios. Once again the only problem is I can't even get to the bios screen with all 4 modules in... Should I set it up with 2, then put the other 2 in and make sure they have the same settings?
