hi, im new here and have a few questions regarding these infamous generic sticks

i have these sticks model on ic Samsung D-rev: (K4B2G0846D) hck0 year/week 1324 .

i cant get these to post at 2400hz. they will do 2133 10/10/10/28 @1.55v just fine though.

i have tried a few different combinations.
i tried 2400hz 10/10/10/30 @1.65v error 23 on mobo
-- -- -- 2400hz 12/12/12/30 @1.67 error 23 on mobo.

vccsa is manualy set to 1.0v also tried 1.11v
cpu i/o is set to 1.15v i lso tried 1.18v

i always get error 23 on mobo.
must i try increase cpu core voltage ?
more vccsa ?
more vcio ?
more ddr ram voltage maybe 1.7v ?
edit ram timings eg. trfp etc etc etc. ?

im sure these ram can do 2400hz. but im not sure what im doing wrong.
maybe its because i have locked cpu ? (non k)

my pc specs :
i7 3770 non k
msi z77 mpower
seasonic 750w
onboard igp.

23 error ( or any near 23 ) = IMC so raise VCCSA and/or VCCIO ( try up to ~1.35V ) When I had Z77 MPower then I had to set slightly higher voltages than on ASUS MVG or Gigabyte Z77X-UD5H boards to keep stability.

I have 4x4GB RipjawsZ 2133 9-11-10 based on HCK0 and they are clocking as good as most HYK0 or HCH9. Some results and settings here:

My kit needs quite low voltage and is running stable @2400 10-12-12 ~1.5V ( I was testing on MSI X79 board where was only 1.45, auto or 1.52V , auto was always ~1.65V ).

One more thing that I noticed right now ... memory is overclocking worse if you are using IGP.

thank u woomack. currently my cpu core is under 1v.
to what voltage can i safely increase vcore to help with the memory oc ?

Vcore has nothing to do with memory voltages.
