F2-8800CL5D-4GBPI on ASRock P45R2000-WiFi: Incompatibility guaranteed

[Caml Light]

Hi! I've problems with these mems (i've tried 2 KITs of them) and my mobo (with the last release of BIOS).
Stability problems are with memory clock at 1066Mhz. Naturally i've tried with many settings, FSB straps, flexibility option and voltages for memory, NB, VTT and SB but nothing.. I've tried with manual timings relaxed at maximum but nothing... OCCT, GoldMemory and Orhos give errors.

It seems that the first mainboard bank is more stable than the second, infact in single channel i've no problems with one memory module only in bank 1, while in bank 2 begin the issues.

At 800Mhz my mems have no problems in dual channel.

Could you help me please?

Thank you in advance!

do you have memory set on 2v?

[Caml Light]

yes... until 2.06V. Could you suggest me any manual settings and the memory SKEW settings to be a stable system? Thank you

Hi! I've solved my issue with this bios setting:

DRAM CH0/1 RCOMP ODT to "63"

Bye!

[GSKILL TECH]

cool, thank for your input

[Caml Light]

it's very important to adjust the "EPP Technology" to "AUTO", because adjusting it to "Profile 0" the system isn't stable, also with DRAM CH0/1 RCOMP ODT to "63".

Now my system seems to be stable, passing IntelBurnTest, OCCT (12h), and GoldMemory.

Thanks to ASRock support! :clap:
