I posted this in the CPU section because the memory controller is integrated and therefore I think it belongs here...

I can not get my i3 to run my OCZ 1600 memory at 1600mhz! I have tried adjusting every setting and voltage and no matter what it will not boot into Windows with memory anything faster than about ~1528. Has anyone else had a problem with this? Or can someone please recommend me a solution? Any help is greatly appreciated...

I have tried a number of timings. By subtimings, do you mean those other than the typical four numbers? Sorry I have never messed with timings much, but I have tried both 9-9-9-24 and 10-10-10-24 (stock is 8-8-8-24).

I am starting to believe this is a problem with my RAM, not my CPU. I mean I had read that the i3's had rather terrible memory controllers, but surely they should be able to handle DDR3 @ 1496 and 9-9-9-24 2t, shouldn't they? If I am wrong let me know, but I have a feeling this should work, especially when changing the timings really has no effect...

my board wouldnt even boot with the x6.maybe this is the problem?

Yep I have it at 8x187 so it should be good to go. The RAM is spec'd to run at 1600mhz 8-8-8-24 @ 1.65v, so having it run at 1496 10-10-10-24 2t @1.66v really shouldn't make it crap out like it just did (threw a blue screen)

are you sure all your other voltages are stable for your OC?.your Qpi/Vtt,your vcore?
for example my 530 had a great IMC and only needed 1.25v QPI/Vtt for [email protected]
and ram at 1600 8-8-8-24.but my i3-540 needed 1.31v QPI/Vtt for the same OC.
could you post all your bios setting with a template so we can see exactly whats what
this bios template might work for your board.just fill in the exact setting that you have set.

Yes I will try to get that up tonight. To quickly address your other remarks, my OC was stable as long as the RAM divider was kept at 6 (so it never really went over ~1200mhz I think). Spring break has officially started for me so I need to pack up some things and go home, so I will post from there as soon as I can.

Keep in mind that the voltages change from boot to boot with me trying a bunch of different settings, so what you see is simply from the last attempt. I have adjusted the QPI multiplier down with no affect on the BSODs.

Let me know what else you need to see.

One thing I am noticing as I test out different settings is that the system seems to be overriding my selection for CAS latency (at least according to CPU-z). Currently, I have 9 selected in the BIOs, but CPUz is reporting a CAS latency of only 7. This could be affecting my memory if it is selecting the wrong CAS, or my i3 if the wrong CAS is selected as I have heard they get finicky about latencies at higher memory speeds.

Sorry to resurrect an older thread now, but just as a follow up I returned my OCZ memory and got some excellent ADATA memory. A little more expensive (no rebate) but it runs at and beyond its specs!
