** Official ** Gigabyte UD3 P45 Series -- EP45-UD3 / EP45-UD3R / EP45-UD3P

[Leeghoofd]

I own the EP45T-UT3P (DDR3 version) and i have a problem with stability at 500 FSB.
What i did was to first set al values manually on BIOS (left side) the adjust MCH ref(0.7v), CPU ref(0.76v) and voltages(CPU=1.2v-LLC Enabled,MCH=1.3).CPU is @3G (6x500)
The problem is that is stable with 2 gigs of ram but not stable with 4 ( i own a corsair kit 2x2 GB DDR3 1600 9-9-9-24 1.8v).
I will come back with a template later after i get home maybe u can get a better look and give me a tip...
Where should i look??
Thanx

I need to give more than 0.08 over the required voltage, my board's DDR3 Vdimm fluctates like hell... strange while the DR2 version is rock stable...

Eg with 1.65 Corsair 1600C8 I7 dimms I need to set 1.72 to get 1.65 in reality, with the OCZ 1.9 Dimms I need to set 2.04 to be stable at 1600mhz C7.

For 4gb I need 1.32-1.34Mch NB voltage at 500FSB-1600Mhz...I'm totally blocked at 580FSB Hyperpi Stable, I can boot higher (600FSB) but the rig is far from stable... same counts for my DDR2 board...

I keep MCH reference just a tad below 0.75, 0.7 is too low here

hi
what do you mean when you said do you set up the pl manually,i will post all my settings a little bit later.many thanks for your help.

Static tRead Value [10] do you set that setting manually or is it still on AUTO ?

How about the MCH/DDR ref? u keep it on auto or set it manually like 50% of
DDR voltage?
