I have problems with my 2400 gskills cas 9 even with looser timings than stock.
What speed? Did you overclock the NB?
Also wondering if anyone else overclocked cpu setting fluctuate a lot. In cpuz my multi goes from 42 to 35 every couple of seconds running prime. Also the FSB fluctuates a lot too?
The NB is set to 2000MHz, 1.3V. I haven't been able to get it to 2200MHz with the voltage at 1.3V, and I haven't seen anyone else set the voltage and speed higher. I'm using two sets of Team Xtreem LV 16GB TXD316G2400HC10QDC01, 4x8GB. 2T. Yes, it has an XMP profile, but it is for DDR3-2400, and I haven't even gotten DDR3-2133 to work. Definitely, 1.8V is too high, as my supernova'd supernova can attest; 1.72V is the highest safe voltage I've seen, although I have seen others run higher voltages past 2.1V (how they did this without melting capacitors in their PSU, I might never know). Is it possible that the CPU multi is fluctuating due to Turbo Core (the auto-overclocking based on application demand)?
For a 24/7 build, would it be better to run my little brothers A10-7850K build using 2133mhz 11-11-11-27 @ 1.5v, 10-10-10-27 @ 1.6v, or 9-12-11-27 @ 1.65v?
All above clocks are tested to be completely stable.
Are you using 4GB or 8GB sticks? What motherboard are you using? Could you post your full timings?
Your problem has absolutely nothing to do with 4MB vs 8 GB ram sticks. It has everything to do with using all 4 ram modules. Try two sticks and all should be well. Also no need for 1.3 volts NB at 2000 mhz. Lower it a bit.
That's good news and bad news. Means I'll have to trade off capacity for speed for a performance hit in certain applications. I'd probably notice it in texture-heavy games and games with a bunch of objects. I'd also notice it with large file handling programs, and in 3D modeling and fluids simulation. One of the reasons I got 32GB instead of 16GB was so that I could run RAMDisk; 16GB wouldn't be enough to mount an OS and an application. I guess I'll just have to alternate between the four and two depending on what application I need to do. I'll run measurement tests once I have an OS installed, of course. It'll have to do until the 7850 gets higher bandwidth.
