I am running this memory on my xfx 680i mobo with a q6700. My cpu (Q6700) is oc'd to 3.33ghz - i have kept the modules clocked at 800 - but i noticed in the bios that the timings (which were set to auto) were 5-5-5-12. the timings are supposed to be 4-4-4-12. I have the timings set manually, and voltage set to 2.2 and havent had any problems thus far - but was just curious if anyone else has had this problem
Also, my memory bandwidth is usually around 5000 mb/s - is this the most i should expect from this ram on this mobo using the q6700?
Thanks in advance
Edit: Does anyone have any experience overclocking these modules? what were your results

The 5-5-5-xx timing is a default timing setting. 4-4-4-12 is technically factory overclocked memory according to the agreed upon memory standard.
As for the memory bandwidth, which program did you use? Some test burst read/write rates while others test sustained read/write rates. Either way 5000 is a bit low. NVidia motherboards are meant to offer superior memory performance (if they are to be believed) and my 800mhz 5-5-5-15 are doing 6400mb/s sustained
Er... T1 CL4 at 800mhz?! No freaking wonder the ram is unstable...
T1 isn't meant for as high speeds as T2. That performance loss is minor. PC6400 is only meant to do 6400MB/s. Try pushing up your mhz instead and possibly loosening your timing to 5-5-5-15 to avoid pushing your memory volts up to high.
