Hey I have this memory. G.SKILL [RipjawsZ] Quad Channel Kit 16GB (4x4GB) DDR3-2400 PC3 19200 CL 11-11-11-31-2N 1.65V XMP Ready Non-ECC (F3-19200CL11Q-16GBZHD) The problem is that my motherboard wont detect this memory as PC 1200 DDR3 2400Mhz. When I run CPU-Z the memory speed is 1600Mhz and it displays the memory as PC3-12800. If I set the timings and speed manually in BIOS it gives me a randomly bluescreen and also fails during Windows Memory Test. These are my specs: Intel® Core i7-3770K Processor Sapphire Radeon HD 7970 GHz 3GB GDDR5 ASUS P8Z77-V DELUXE, Socket-1155 Corsair AX 1200W PSU Kingston HyperX 3K SSD 240GB 2.5" G.SKILL [RipjawsZ] Quad Channel Kit 16GB (4x4GB) DDR3-2400 PC3 19200 CL 11-11-11-31-2N 1.65V XMP Ready Non-ECC (F3-19200CL11Q-16GBZHD) I checked many times to see if my motherboard supported this memory and according to ASUS it should. Any idea why I got this problem? Thanks in advance Ole
The amount of RAM will dictate if you can run at those high mem speeds. Do a test with two modules only in the appropriate slots and see how far that takes you. The IMC of each CPU is different. Intel's max supported is 1600. Thereafter is overclocking. The more memory modules you use, the higher the controller load. Some IMCs play along nicely and others don't. A sensible OC for the RAM will be 2133. I have tested the mem performance with my 3770K at 2133, 2200 and 2400, and above 2133 there is hardly any difference, in fact, some benchmarks start to show a deterioration. Thus test the following. With all 4 modules, set it manually to 1866 and see if it works, then 2133 and see if that works. Try 2200. Make sure your mem voltage is set to 1,65 or slightly above as the board's applied mem voltage is usually slightly below what you set it to in the BIOS. If you are able to get all 4 mem modules to run at 2133, say thank you and move on. 2400 is a number that may not be achievable. You could try looser timings at 2400 i.e. 12-12-12-36 and see if it then works, but that would defeat the object of the higher frequency. IAt 2133 you may be able to even run tighter timings, which will offsets the slightly lower frequency. I run mine at 10-10-10-24 and have even achieved 9-9-9-21, but the memory performance shows no improvement, so whats the purpose. You may also try setting the I/O voltage to 1.07v's. SA to 0.965v's to see if that helps.
