F2-8500CL5D-4GBPK+GA-EP45-UD3P Rev 1.6

[Railroader]

My Computer will not boot with memory installed in slots 1 and 3, will boot with memory installed in 2 and 4, but even after configuring bios as stated in the settings posted here, my computer will not boot into windows, I just get a BSOD, and then a reboots. I returned a set of memory modules thinking one may have been defective, this appears not to have been the case, as the replacement modules are doing the same thing. Do you have any updated info from GigaByte on how to proceed with this issue. I believe I have download the latest bios for this board. Thanks

Note: the F26400CL5D-4GBPQ Modules Work fine.

Did you enter your base timings manually, along with the DRAM Voltage and Command Rate to 2T. With the 8500s if you are using auto, it may be kicking the command rate to 1T. Another thing to check would be to raise your NB Voltage .06 to .1

Set Perormance Enhance to Standard
Set system Memory Multiplier to 3.20b
Set DRAM timing slectable to Manual
Set Memory timing to tCL 5 tRCD 5 tRP 5 tRAS 15
Advanced Timing Contol -Changed Command Rate CMD to 2
Changed DRAM voltgage to 2.2 (Sticky Stated 2.1, this option is not available on my bios setup.)

Anything Else need changed? Thanks

Think you should be in business, if any problems if you could post your BIOS settings

Note: As I posted, after I did all that, still does not work, get BSOD, and lots of reboots.

How does one copy or print the bios settings, or do screen shots. Thanks

[genetix]

you write them down or take a camera/phone and take a picture.

I have the same board and memory and got 1 stick 2 work at 1066 ,but 2 sticks never have .Ive tried 3 boards and 2 sets ram . try 1.98volts its the only volt i changed. adv clocks should be 700mv and 900 mv pci and the pci express MHZ 96 ..the rest of your settings look fine. However dual channels dont work i'm waiting on a new board my 4th 1 . wish i could exchange this ram for its big brother the PQ is much better ram .
