Reading more on Corsair website it seems there are JETEC settings of 5-5-5-18 (not sure about voltage, maybe 1.8V) and EPP settings of 4-4-4-12 at 2.1V. However, even with the latest BIOS (F6) my board seems problematic with EPP mode enabled or maybe the combination board + ram, so that setting is disabled. Maybe that is the reason the timings are 5-5-5-18.
Last night I tried briefly to enable EPP and I also set EPP Voltage to be By EPP mode, but there were few weird things. Settings were accepted and first boot after exiting BIOS looked normal. Then I opened Everest and noticed in the Sensor section ram voltage 2.16V which got me worried coz earlier I read in general to keep it under 2.1V (although it depends on manufacturer and model). So I restarted Win to go to BIOS and the PC just shut down. I am pretty sure I selected the Restart option not Shut Down. I pushed the power button to power up, and it seems to get stuck even before POST, my DVD-RW led was flashing, like initialization, but it never gets over that step. No beep, no POST, blank screen. You have to hold the power button to shut down again, and try few times until it finally gets to POST and BIOS. Then I returned setting to previous, EPP disabled and now it is OK.
It was doing exactly the same when I first assembled it, until I read one post recommending to disable EPP, after that working fine 7 months now. In the initial F3 BIOS that setting was enabled and in the latest F6 disabled by default. Guess GB received lot complaints about this issue.
Since I can not count on the EPP setting, is it better to keep it disabled, go in BIOS MIT Dram Configuration, set to Manual and set to 4-4-4-12? Would I need to adjust any of the more advanced timings too, except these 'standard' timings mentioned? Then also should I set System Voltage option to Manual, not touch any voltages except DDR2 Voltage which should be set to +0.3V because Corsair specifies this ram as 4-4-4-12 at 2.1V? Would that work? In MIT do I have to also set ram frequency from Auto to Manual and choose 800MHz myself (since timings will be manually adjusted)?
Sorry, too many questions, just trying to figure this out. I am very pi**ed at Corsair. When I buy C4 I expect to work as C4 out of the box so to speak, without this much fiddling.
I wanted the HyperX from the start but where I live I couldn't get them on short notice and needed the PC urgently. Had to go with Corsair. :( With your recommendation not to mix brands now I'm stuck. Seems I'll have to ditch these 2x1GB modules if I want to change to HyperX. :(
