Problem with Asus P5Q3 - DDR3 1600 Ram

[Tyuss]

Hello,
I was looking for answer at the internet for my problem but after hours and days of searching got frustrated. I would love get some help from you.

So I have Asus P5Q3 with Intel Core 2 Quad Q9400 and decided to upgrade to 2x4gb with 1600mhz of ram. The web states that 1600 frequency is available but just at orange slots. (*DDR3 1600MHz or above DIMMs work only on the Orange slots for one DIMM per channel.) So Ive done that but I get BSOD`ed while playing games.




So, could someone look at my pc specs and say, what is wrong and what should I do?
Edit: I have updated to latest BIOS version. Im using Windows 7 Professional 64bit

Just going by the model number of the modules shown in the SPD tab--> Part Number field of CPU-Z that you posted, I'm assuming rated timings at DDR3-1600 are 10-10-10-27 at 1.5V. The modules are currently running at DDR3-1333 (666.6MHz x 2) and 7-9-9-24, which should probably be 9-9-9-24 at that frequency. So increase the CAS Latency from 7 to 9 w/ the DRAM voltage at 1.5V. And the only way you can run the RAM at their rated frequency of DDR3-1600 is by increasing the FSB to 400MHz, since the 4.00 DRAM multiplier (1:2 FSB : DRAM ratio) is the highest available on any strap (400MHz x 4.00 = DDR3-1600).

+1 above. Those memory speed are acheived by overclocking the FSB. As he told, try CAS9 and 1333mhz, CAS9 1333 and CAS10 1600 will give similar performance results. 775 was running much higher memory volts so you could try to raise a little bit from the 1.5v spec on the ram, lets say maybe 1.51 or 1.52. I had trouble running a 1333mhz 1.35v kit on a 775 platform, it wouldnt run anything lower than 1.41v but the ram was OK on a 1155 platform.


Your mixing quite old and somewhat new stuff together, sometimes you need to tweak a little bit
