no 1T command rate @285 HT ref. clock, but works @ 300
Hi!
I got a rather confusing problem, maybe someone can give me a hint or explain how the following is possible...
Got 2 sticks of gskill ripjaw ddr800-cl8 that flawlessly run timings of 8-8-8-24-1T @ 1666mhz (ref. clock 250, x6 1055 @ 3.5, turbo off).
ddr760@ ht ref. clock ~ 280-299 and Command rate 1T is causing errors in memtest86 within seconds - even with the slowest possible ram timings. only changing 1t to 2t results in no errors again. :confused:
(cpu @ default, ht link and nb around 2000mhz).
well, so far you might say that my memory and/or cpu/mobo aren't capable of running 1t @ that ref. clock but now imagine the following:
ht ref. clock @ 300 and higher ram, cpu and northbridge/ht link speeds and memtest can run with CR 1T for hours without errors.
anybody got any idea how that's possible?
In intel 965p times one might answer it's got to do with nb strap changing but that obviously shouldn't be the case here as the NB ratio can be controlled.
Thanx for reading the above story, I'm thankful for any answer or even question if further details maybe needed.
Best regards,
Albertini
binge ain't ignoring anything imho
I gotta say thank you to bingo and the asus team, i practically expected asus to forget the m4/m3/m2 series with the release of the 890 goodies, but i do have a new bios that fixes the pstate and allows me to do some bios oc'ing for once. Only one issue though binge...
The bios is actually not allowing the same oc that i was getting with 3107 using kstat, i've tried all the normal things upping the voltage, turning off turbo core, underclocking and loosening latencies.. still it crashes within seconds.
my findings based on the limited time i had on the 3205 bios is that the northbridge clocks went up about 200Mhz easy, and i haven't tested further, the voltage seems to be taking when i set it.
i can also oc via the fsb with little stability and my memory seems to oc much further than 3107, by about also 200mhz.. timings may have not been taking or what not, but it's working fine now
only thing i'm seeing is the oc not being stable where t was previously stable.. i have the mem in the far outside slots atm and i haven't tried the other slots to try and remove that possibility however i'm gonna give it a try in a sec.
