Default Overclocking F3-14900CL8D-8GBXM

Hello all,

I overclocked my RAM (1866, cl8, 1.5V, with xmp) to 2200mhz, 9-10-11-21, 1T.
Using 1.6V on the dimms and +1.1V on system agent, i/o analog and i/o digital.
Could it be pushed further? (without a too dangerous voltage)
Maybe using the advanced timings? (I don't understand them )
I'm using a Gigabyte Z87X-OC motherboard and a 4690K CPU, by the way.

Thank you for any help you can provide!

Try DDR3-2400 10-12-12-28 1T at around 1.6V. The Z87X-OC should find appropriate secondary timings by itself. You can tweak them and the tertiaries for performance afterwards and might have to adjust SA and I/O(a/d). However in my experience +1.1V are way too high for 2200/2400 with a 4690K.

It also works with 1.550V and system agent etc on auto (0.000V), but haven't tested stability yet.
Also, 2400mhz won't boot, even with 15-15-15-35 2T @1.6V and +1.1V..
Maybe, tuning the bclk helps? Currently it's at 100.0mhz.

No, leave the BLCK at 100. Can you please post a picture of your memory (frontside)?

Then i can probably give you more concrete hints or some UEFI screenshots with settings to test.

System Agent should be +0.1V and more for DDR3-2400.

That is a good overclocking kit so you can achieve very good results or leave it to the current DDR3-2200 settings, which are pretty good.

Thank you

It's a F3-14900CL8D-8GBXM kit.

Currently, I've got 2200mhz 10-11-11-24 1T @ 1.6V and system agent etc @ 1.1V. CPU @ 4.7ghz 1.26 vcore and 4.3ghz uncore, which I know is stable. But I sometimes get BSOD's while gaming, so that must be because of the RAM.
How can I stabilize it even more?

Thank you

2200mhz is stable now .
But if I try 2400mhz @1.7V and system agent etc +0.16V with timings on auto and enhanced stability on, it won't even boot....
Am I missing something?

Thank you

Difficult to say, maybe not enough VCCSA, maybe timings are too tight, check these and try different values to see if it improves.
