Overclocking 2400Mhz Samsung Green's Problem

Hi folks

Firstly thanks to Asus for making such a great Motherboard - Maximus V Gene.

Here's my problem, Im trying overclock a pair of 4GB Samsung Green 30nm sticks of DDR3 up to 2400Mhz but cant seem to get a stable POST/Boot.

I have OC'd my i5 3570K to 4.4Ghz and the RAM is currently sitting at 2200Mhz with timings of 9-11-11-21-1T 1.55V

Has anyone else with an i5 3570K @ 4.4Ghz managed to clock this RAM up 2400Mhz?? I know it can be done on the i7, just wondering if it can be done on the i5

Im fairly new to RAM overclocking so that's why I could use the help.

Appreciate any feedback you may have.

Load the loose Samsung memory preset and see if you get POST.

I tried that, 11-11-11-28 2T @ 2400Mhz with 1.5V and 1.6V, no joy!

Sounds like your CPU has a weak memory controller. TBH if it is not POSTing with that preset your best bet is to tighten up as much as you can around DDR3-2200. It will actaully be faster than running at faster frequency with very poor timings...

Thanks for the reply, is there anyway to improve the CPU Mem Controller on the i5 Ivy?

When you say tighten up (something I have heard a lot of when RAM OC'ing) is that basically trying to get the numbers as low and stable as possible? Is there a particular way / method of doing this that will make my life easier?

Whats a good starting point etc?

Thanks again

Just spent about 1hr 30mins testing new timings and tightening things up.

2200Mhz @1.5v 9-10-10-19 1T

Best I could get and im happy with that 🙂

Is that good folks??

maybe the cpu has a weak imc 🙂

this is my run, samsung ram!

Perhaps, but im running an i5 3570K. Im pretty sure the i7's can run with higher clocked RAM than the i5's plus you have yours running at 5Ghz so the CPU can handle the higher speed of the RAM.

I was just wondering if the i5's could take 2400Mhz frequency.

I have a maximus v gene, i5-3570k @ 5ghz with samsung green ddr3 1600 running at 2400mhz. I suggest starting at 1.70-1.75v for 2400mhz and change the ram voltage frequency (under drm settings in bios) from auto to manual (default is 300) 320-400.

With 1.85v I was able to boot into windows @ 2666 mhz but couldn't get it stable enough to complete any benchmarks. With an i7 and proper cooling I'm sure it could be done. Here is a good read:
