Live MB OC Report :: ASUS Rampage Extreme

having a hard time to get IBT PASS @ 485 FSB.
necessary CPU VTT rise significantly from 1.2v (471FSB) to 1.32v.
Hard locks (mostly) / BSODs / reboots occured when attempting to run IBT when I leave all CPU GTLs in auto.
With a slight tuning of CPU GTLs IBT does run but only 80% hit rate (8 out of 10)
So that means still has a way to go...I guess to run 500 FSB a minimum of 1.4v VTT will be a must...

can you post your new settings with q9550 step e0 please? thanks

OK Back to track.

I've made a fresh start from where I begin.

CPU GTLs all on AUTO
NB GTL +40mv
vNB 1.577v
VTT 1.4v
CPU Freq. 477x8
vCore 1.2v

Skews:
CPU Skew: 400ps
NB Skew: 200ps

New discovery: Too much CPU to NB Skew delay (300ps or above for my case) will cause lockups.

EDIT: NB STRAPS WILL AFFECT NB GTL TUNING AS WELL...GUYS PLEASE HELP TO TEST WITH DIFFERENT STRAPS / GTLS
For my example, using 468FSB for testing
200 STRAP need +40~50mv to pass IBT, while 333 STRAP need +70mv using the same VTT, vNB, CPU GTL

Interesting with different GTL at different straps.

I´m working with a E8400 C0 at 475, Corsair 2x1 at 1900 777 21 1N Strong tRD6 strap 333 and I found out that strap 200 and 400 give me slightly less performance then strap 266 and 333 and of 266 and 333, 333 give me slightly better performance.

Setting right now

CPU GTL0 +40
CPU GTL0 auto
NB GTL +40
CPU Freq. 475x8,5
vCore 1.43125
LLC disabled
PLL 1,50
VTT 1.20
vNB 1.59
DRAM 2,16

CPU Skew: 300ps
NB Skew: 200ps

Working to get down DRAM, NB and VTT volt.

Prime95 blend freeze or reboot with vtt 1,10, nb 1,59, ok with vtt 1,20, nb 1,59.
LinX 50 loop ok with vtt 1,10, nb 1,61, error somewhere between loop 35-45 with vtt 1,10, nb 1,59.
HCI design Memtest ok with vtt 1,10, nb 1,57.

So with vtt 1,12-1,20, nb 1,57-1,59, should be stable, then I have to bring down the DRAM volt.

NB GTL +40 seems best for me.

can you screen your accurate settings in to bios and post it pleaseee? excuse me for my english i'm italian
