Gigabyte B85M-DS3H-A 8GB RAM!?!?

[agriffin15]

Good evening,

I have 2x 8GB Sticks of PNY DDR3 1600Mhz Ram in which I installed onto the board (They didn't come in same set) installed onto my Gigabyte B85M-DS3H-A Board. I have currently installed on it an i5-4590 3.3ghz and an EVGA GTX 750Ti 2GB Video Card. Is there a setting in the Motherboard BIOS that I missed that allows for more then just 1 stick up to 8GB or is this a known issue and can be fixed?

It is assumed that the memory modules are compatible with the motherboard(?) If not, then that is the problem, and known compatible memory will have to be found instead.

No two memory modules are exactly alike due to variations in characteristics. Because of this, two modules may not work together (properly), even if they are the same part number.

When pairing two modules, it is usually advised to get a dual channel kit where the modules are guaranteed to be compatible. But when trying to match two individual modules (not from the same kit), then there may be compatibility issues, as is suspected here.

First clear CMOS and try ONE of the new modules. If the system works OK with that module, then install the second module also. If the system doesn't work properly with ONE module installed, then try the other module.

Could also try raising DRAM Voltage a bit in BIOS by 0.05 V, and see if that helps; don't exceed 1.65 V for DRAM Voltage, as this might damage the memory.

If still have issues, then could try another module and so on until a compatible combination is found. But this may take awhile and might cost a bit more also (shipping, restocking fee etc).

Perhaps the better option would be to get a dual channel kit to replace the two individual modules. The individual modules could be returned for refund, or sold, or kept as back up (if they work ONE at a time).

I have booted the system up with both sticks. Both are running correctly and areally not ca using issues. As stated in the manual (surprisingly had to consult it for once) it shows that the slots alternate from each other and goes 1,3,2,4 and are light and dark colored so it's pretty straight going on this board. It's clearly not showing 2 sticks installed on the board at all via bios.

What are the part/model numbers of the DIMM's please?

BIOS up to date?

I believe the BIOS is updated to the current. The DIMM Numbers are as followed:

8GBH2X04E99927-15-H
1351 P040588

8GBH2X04E99924-15-H
1327 P24744

Thanks for the DIMM details. Unfortunately the labelling on these PNY DIMM's does not seem to correspond to PNY (internal) DIMM part numbers. And there doesn't appear to be a part number decoder available for decoding PNY DIMM label codes, so it can't be confirmed what the module specifications are.

First clear CMOS. Do BOTH DIMM's appear in BIOS now? If not then -

try ONE DIMM at a time, and if necessary try different memory slots as well. Do both DIMM's (installed one at a time) show up in BIOS?

Do the DIMM's show up in Windows Explorer, and/or in CPU-Z, and/or in HWiNFO?

I have tried both and this time I came up with the answer. This time, the Memory Module failed completely and now isn't allowing a post screen or video and shuts down the PC within 5 Seconds. So, I guess repeatedly testing allowed the module to fail completely. I setup an RMA thru the company that I ordered the stick from and is being returned for an exchange.

Thanks for the help
