SS is screenshot. which BIOS version you're using?
i'll say 1.50V is still safe for Venice + stock cooler.
remember disable cool and quiet, loose up RAM timing.
disable SATA3&4 (just try it)
this mobo can take up to 355HTT on stock voltage, tested by myself.

wah, really? can give me the settings detail, like RAM timing?
im using the kingston value series.
the bios version im not sure.
i thinks it's phoenix award 6.00pg.

so i need to:
loose RAM timing, disable cool & quiet, disable SATA 3&4.

tried increase v-core to 1.5 and can get 260 Mhz & do SP2004 for 30 mins.
havent get chance to set it higher. probably tonight.

@xixo_12
probably tonight will get the SS. Temp is around 45-48 C, 260Mhz x 9 @ 1.5v Vcore when doing
SP2004 for like 30 mins. Temp checked by CoreTemp.

try 3-3-3-8 with 2T or 3-4-4-8 with 1T because you're using 2x1GB sticks
(CAS-TRCD-TRP-TRAS, suggestion only & depends on RAM speed)
phoenix award 6.0 is mobo firmware version
not bios version la, see CPU-Z 3nd page-BIOS-Date smile.gif

nVidia mobo need to set HTT multiplier lower (4x, 3x, 2x) keep it close to 1000MHz wink.gif
lower it won't affect performance but better stability. play safe with temperature & voltage.

also your RAM divider/ratio thing, lower it to 533 or 400 when you overclock it will raise back follow ratio.
DDR800 = 2/1 x2
DDR667 = 5/6 x2
(DDR600 = 3/2 x2) this is special memory divider rclxub.gif
DDR533 = 2/3 x2
DDR400 = 1/1 x2

243 *12 CPU multi = 2916MHz
243 *5 HTT multi = 1215MHz (too high, not stable, lower it to 4x /3x)
243 *(3/2 x2) mem div = DDR729 rclxms.gif

lower down the htt multiplier..
use divider that ram is lower than cpu..
then up the fsb back..

find out the max of your processor first then only find out your ram..
after that find the best tune..

maintain it first...
just find what is the max ur procs can go with the stock vcore..



anyway if u use stock heatsink and planning to use your OC setting as daily use keep the vcore to stock..

need some explanation and help here.

I'm using am2 6000+(3.25Ghz), fsb 250, ht multiplier 4, cpu multiplier 13, dram freq=406mhz.
Core Volt = 1.416V, Memory Volt = 2.1V, HT Volt = 1.3V, NB Volt = 1.2
Recently change the stock cooler to hyper 212 coz stock cooler fail prime95 at this speed and temperature drop to:

QUOTE
------------------------------------------------------------------------
                                 stock            |      hyper 212
------------------------------------------------------------------------
                            idle   |    load     |     idle      |    load
------------------------------------------------------------------------
core               =     35    |      -        |      27      |      -
core 0            =     43    |     62       |      35      |    55
core 1            =     45    |     60       |      38      |    53
------------------------------------------------------------------------
pcmark05       =         73++            |            70++
------------------------------------------------------------------------


why does the performance drop when proc getting cooler? (i'm using exactly the same bios setting)
is there any effect on performance if HT bus speed < 1000?

Added on August 30, 2008, 7:21 amnvm. problem solved.

i hv a question about temperature.. my concern is temp on core#0 is way higher than core#1 (about 8-10 degree different).. i took the reading from cpuid hardware monitor.. is there something wrong with my proc? rite now i oc to 3ghz (273x11) @1.4V.. another prob is the core voltage in cpuz only show 1.376V.. i read around n it says something like vdroop ( idunno wat that really is) .. how to fix this? anyone help me pls..

core0 /core1 have 8-10°C different? can you adjust the "temperature reading interval"(for CoreTemp) to higher value?
vdr0p is voltage lower than setting anytime no matter idle /load.
vdr00p is voltage lower than setting when 100% load.
is your 3GHz stable when 100% load? if not you need a little higher vcore to compensate the drop.

hmm.. so thats wat vdroop is.. tq.. in my case the voltage is always the same when idle or under load.. when i set 1.4v it shows 1.376v.. for the temperature.. the different is not much when idle (2-3 degrees) but when i ran stress test the different become bigger.. im worried coz temp on core#0 might reach 60C while core#1 only 48-50C which i think is safe.. i look at bios and the temperature never exceed 47C.. so now im confuse which one to look at cry.gif yes at 3ghz its stable as i already run orthos for 12hrs with no error.. i dont hv core temp.. sweat.gif i'll download later..
