ASUS Intel Beta BIOS Releases and Official Support

[mjgr33n]

I did some testing and I was able to get 1866 7-9-7-24-2T at 1.5V with XMP timings except for tCWL at 8, 1:30h Prime stable (haven't had time to test further).

I'm also not perfectly comfortable with 1.65V, but considering these are PSC chips after all (most of them run like that), and the RAM doesn't stop scaling earlier like some other people experienced, my guess is that it's reasonably safe.

And I don't believe there is much difference between a plain heatsink and one with twists and bends as long as you get just enough airflow to cool it down a little (my kit gets only mildly hot while Priming at 2133 1.65V).

Hmm, your response has made me think about trying 1.65v then )))) Plus I guess having 3 viper fans right above the memory on my TFC 360 would keep it cool.

I am surprised you need to have tWCL at 8 though with CL at 7, they should always be the same or at least the memory should always be able to handle them both being the same, although I suppose there is always slight variations in kits, have you tried posting on the gskill.us forums, I would think they might replace them for you given that as it should be able to run at those parameters, I actually have 3 of these kits and all of them run with tWCL and CL being the same.

They can run at equal CL and tCWL, just not on this board, so it's most likely not the RAM itself. RMAing the would be a pain for me considering I have no other DDR3 kits lying around, and it would take upwards of a month for me to get them back considering I live in Brazil.

BTW, I found out 9-10-9-28 was not stable after all, I got a Prime fail after 8h. I discarded 7-11-7-28 and 8-11-8-28 after Prime fails in minutes, and am now trying 9-11-9-28, hopefully it'll finally be stable, or I'll just go back to 1866.

I just tried 2133 9-10-9-28-2T @ 1.65v and that was not stable for me, but then I am running 4 of these sticks, so back to 1866 for me, at least I know 1866 - 8-9-8-24-2T runs stable for me at 1.5v which is pretty good for 4 sticks ))), will keep it at 1866 unless ASUS provide a new BIOS with some more memory tweaks, but as from next week I will only be able to test at weekends as will be staying in hotels and B&B's for the next 4 months, so not sure how much time I will get to test, need to buy a laptop now :P

Looks like a new BIOS has been released for all the P67 boards on the Asus ftp server.

Not sure if it's beta or not. BIOS 1702

Not for all - just for the Deluxe and Sabertooth so far. They just have added 1702 for the evo too.

Tried 9-11-10-27 ? Only way to get my 4gb dimms running at 2133Mhz... wanna quick test the rams try HCI memtest in windows... unstable ram timings will error out under 10 mins...

Prime95 Blend usually fails for me in under 10min too, it's either that or 8h+, very rarely anything in between. And I'll try 9-11-10 when I get home later, thanks for the tip
