Asus M3A78-T + 9950BE overclocking... wow its all new again

[gOtVoltage]

Ive got C1E disabled. Im going to look into the ACPI states right now, thanks.


Now that I read that its best to keep NB below or at 2600 I think I found whats causing it. 246x11 would have put me over 2700 on the northbridge. Lowering the NB multi caused the problem to go away. Ive got a chart that I wrote out on paper which pretty much has what multi to use for the NB at 2600, 2400, 2200 and 2000 speeds for any given HTT so that I can remain no higher than the targeted NB speeds. Ive also got a chart for which HTT speeds I need to attain 3.2ghz from each multi going from 10x to 16x just so I know which HTT to test to find my max. I plan on doing the same thing for 3.3ghz and possibly 3.4 so that I can find my max. Makes things a bit easier to have something to refrence without going to a calculator.

Once I get office installed Ill make a few excell sheets people can use for their own refrence.

2700nb seems to be the Max for 9x50's.. Ive tested several CPU's( 2500 to 2680 is optimal) Depending on cooling and Volts run on Mobo . This ive found with most of the CPU freqencies ive used while running Ganged and Unganged (Both6400/8500 ram)..

Sometimes the Bios is the biggest factor with this.. a good Bios = great Oc period.


Note:
Ive found that the HTT likes 230/250 max Most Ram freqencies ive tested . Even though I can push the HT to 5200 it is Usually = to the Max NB you run for your given Oc with out exceeding 5200 .


My conclusion,,
Stable HT above 5200 and NB above 2700 might not be possialbe until 45nm and DDR3 Mobos which is desinged for HT5200+. Then we can push that limit further i believe.
More so i believe the Mobos and Bioses ATm are responsible for the limits of 9x50's. I can push my CPU to 3.55 with 2000HT 2000NB but Mobo holds it back( ,,Particulerly the PWMS cook with the Voltage it needs to Do it.

Your chart would be very valuble and save lots of time tweaking . Especially fo those people that have no unlocked multi going UP

P.S. i think CPU-Z need more updates for GX/750
