I'm all too aware of how important loose tRFC is; that's one of the biggest reasons i bought this board.Originally Posted by Tony
Leave tRD on auto, Oskar knows how to auto a board up
Chipset voltage around 1.4V, 5-5-5-18 trFC 52 or higher and rest at auto, 1.8Vish for 1000MHZ and off you go, 24GB of 2GB modules here and they all do the same in any combination.
(My previous mobo could only do 42 or 51 on auto, which was craptacular.)
I had tRFC at 55 at least.
I actually had it at 70 for a while as well, but it was reading as 63...apparently 70 doesn't work i guess.
Didn't matter though; didn't help.
I'd say the best way to describe running 8 GB on this mobo is nonsensical.
I've managed to get it stable by running auto.
Not a single timing on the RAM touched, because it seems if i do, it suddenly becomes unstable.
The irony of this BS is that the subtimings are actually much tighter than when running set manually
I'm convinced that there are some other hidden subtimings at play that are being changed when timings are set manually, otherwise it makes absolutely no sense.
I'll post a bunch of pics explaining the mess later (gotta get to work), but overall, i'm extremely unsatisfied with this mobo.
I bought it to be able to tweak 8 GB; instead it is unstable for any 8 GB configuration, overclocked or underclocked RAM, unless i leave it all auto.
I could do that just fine on my P5B Deluxe...coulda saved myself this waste of money.
BTW how important is Clock Fine Delay for stability?
I thought it might be what was causing my issues, since it's one of the subtimings that always changes depending on ratios, timings, etc.
But then what i ended up getting seemingly stable uses very tight Clock Fine Delay, so that theory got debunked.
What hidden subtimings could cause massive issues Tony?
Edit: here's one of the biggest jokes of a screenie.
I'll post more later, gonna be late for work.
Failing @ underclocked DDR2-720 5-5-5-18 no less.
