Just got this board as a replacement for a dead M4N72-E which i had been succesfully overclocking prior to me damaging the Chipset.
I have seen the posts on here of Phenoms running on this board at over 4Ghz, like 4636Mhz?? I was wonderig if CPU overvoltage had to be enabled with the jumper in order to get those values, also is the jumper safe to use, I have heard some scare stories where moving the jumper has put like 1.69V through the cpu even if the voltage is set manually in BIOS.
The reason I ask is I can't get my 1090T stable at a frequency any higher than 3.96Ghz, even if I bump up to exactly 4Ghz, it is not Intel Burn Test stable.
The Vdroop is weird to me as the M4N72-E even with 4+1 phase power and only 4 pin CPU power socket didn't display these charachteristics as bad, for example 1.5375V on the old board would give me 1.488V on the vcore with some fluctuation down to 1.472V, Setting 1.55V on this board drops to as low as 1.408V with a more steady 1.42V, still the CPU is stable at these voltages at the sme speed, so maybe the board is actually doing a better job by needing less voltage than the other board to stay stable??
If i manually set the voltage for the CPU/NB, AIDA 64 reports it as unchanged, If I leave it on AUTO and overclock the CPU/NB. AIDA 64 reports that for speeds up to 2600MHz the voltage is 1.35V and for speeds up beyond that it reports 1.45V, these seem a little high to me, given that the M4N72-E was stable at 2600Mhz at only 1.1875V on the CPU/NB. I have contacted ASUS about the issue. If using Turbo V, the the CPU/NB voltage can be set, but even setting it to 1.45V in Turbo V causes the system to lock up,
All spread spectrums disabled
Nvidia NCC disabled
AMD Cool and quiet ENABLED ( at multipliers above 18.5, AMD cool and quiet stops working any way, 18.5 and below and it functions just fine)
Here is what I have so far: (stable with Intel Burn Test @ 6144Mb settings or Maximum)
CPU: AMD X6 1090T @ 3.96Ghz (all six cores) (turbo disabled) @ 1.55V (BIOS) (droops as low as 1.408V!!)
HT: 220 Mhz
CPU/NB: 3080Mhz @ 1.45V!! (AUTO)
RAM: 2x4GB DDR3 Crucial Tactical Tracers 1600Mhz @ 1760Mhz 8-8-8-24 1T
HT link: 2200Mhz
VDDA Voltage: AUTO
NB Voltage: 1.24V
HT Voltage: 1.24V
Nforce Voltage: 1.24V
Peak Temperatures on cores while under load (Intel Burn Test) are 54C with the socket Temp matching this at 54C.
On the old board, the socket temp would get up to 62C with the cores reporting 57C, I really think this particular CPU is capped at 3.96GHZ but I want more, My temps aren't that bad.
The Second picture shows my Idle Temps, I am using a CM690II Advanced case, fully configured fan wise, Aero Cool touch screen 5.25 Fan controller. 1050W PSU, Tuniq Tower 120 Extreme Cooler which has been lapped, as has the CPU, using 1000 and 2500 grit sand paper.Edited by Nomad8459 - 4/4/12 at 3:20pm
