ei.. sry.. see wrong.. duhduh..     VTT not sure.. 

i think NB chip nowadays just same as graphic card chip, can tahan quite high temp.... heard tht if below 60c is ok refering other forum cause max temp for nb is around 80c...

i think will be unstable a bit gua.. coz i OC my proc ar 445X9 also not stable.. NB temp at 45/46C.. increase voltage still same.. hmm..

@tkh_1001.. u using wut FSB X Multiplier.. wuts ur vcore for proc..?

yaka..i think not really same..as the hsf can mount fan on it..so will cool down the NB oso..

haha the dk been reserved..waiting got payment then ship to new owner new baby didnt ripe out yet y selling ur xeon?got quad?

owh..haha still stay calm coz didnt oc yet in new mobo..nope..as i tols stratos oso i dunno much bot ram setting n tweak myb u can ask others bout it

Haha.. same here.. i search but cant find related to this board.. so anyone..?

Additional Setting Ranges:

MCH ODT Latency: ODT (On Die Termination) is used to match the MCH output impedance to the termination resistance of the RAM. Use of 1-2 is fine in most cases. Even for 4GB overclocking we did not find that more than a setting of 1 was required.

Write to PRE Delay (tWR): Range is from 10-13. For high RAM speed, use 12 and above for stability; for benchmarking 10-12 will be faster. Lower is faster.

Rank Write to Read (tWTR): Range is 9-11. Use 11 for stability and 10 or 9 for benchmarking. Lower is faster.

ACT to ACT Delay (tRRD): Range is 2-5. 3 is a good setting that allows high enough FSBs for most users. Higher numbers result in less memory read performance.

Read to Write Delay (tRDWR): Range is 8-9. 8 is ideal for most users; higher values are slower.

Ranks Write to Write (tWRWR): AUTO
Ranks Read to Read (tRDRD): AUTO
Ranks Write to Read (tWRRD): AUTO

The ranges for all these settings are quite well manipulated by SPD and BIOS. For those wishing to experiment, 4 is the lowest and most aggressive setting. 5-4-5 may work for SuperPi type benching. There is a slight write/copy speed increase with tighter settings, but this is only useful for the extracting the last ounce of performance. For stability these are best left on AUTO

Read CAS# Precharge (tRTP): 2-3 works well on this board for most users. 2 is used for benchmarking while 3 and upwards are best for stability.

ALL PRE to Refresh: Range is 4-5. 4 works fine with quad-core CPUs all the way to 475 FSB. A setting of 4 is fine for most benchmarking, unless shooting high over 500FSB.

GTL REF Voltage control: Enable / Disabled
"CPU VTT reference voltage for determining host bus high / low level." - This setting can be useful or detrimental and is highly dependant on your individual CPU. You may find that you can acheive a higher and more stable overclock by tweaking these values. The values are strongly tied in with the CPU VTT voltage, so it can take a bit of experimenting to find the correct settings. See the VTT/GTL REF guide here.

Update: After further testing with another 45nm dual core cpu (E8400 & E8500), I have found that on my systems, there was absolutely no need to have the GTL REF Voltage Control set to Enabled. I was able to hit 500FSBx9.5 with relative ease, and 540FSBx9.5 later on - Of course, as VTT & GTL REF settings can be different for each setup, you may find that a small amount of tweaking will work for you. The trick is, for 24/7 overclocks of relatively sane proportions, less is more for the VTT (i.e. Leave it alone unless you are unstable), and the same goes for GTL REF.

One of the reasons that the board can retain stablity when the GTL REF is set to Disabled is that rather than it actually being disabled, it is simply fixed at 67% and 67% is what DFI have found to be the optimum value for GTL REF at any given VTT.

Enabling the GTL REF setting will allow you to fine tune the percentage figure should your setup require it, however, it is very easy to tweak these settings too much +/- and miss that sweet spot, and often, you will find that the sweet spot was at 67% to begin with.

I have tested with a Q6600 G0 and this responded well to the 67% (Disabled) setting. Again, this doesn't automatically mean that yours will. My last Q6600 G0 responded better to fine tuned GTL REF and a slight bump in VTT, so it really is a case of experimenting and seeing what works best for you.

There is another factor that can have adverse effects on your VTT/GTL tweaking results and that is temperature. From my own tests, I have found that GTL REF tweaking is less effective when using air cooling and a higher Vcore, and similarly, when using sub zero cooling, I found the GTL REF to be incredibly sensitive and the slightest changes caused adverse affects - This is something that I would like other people to comment on because I would like to explore it further

I will add more as I get to it...

yes u need reinstall OS 1st after change mobo..coz all driver already different with previous mobo...

what are the coolers that can fit properly on this mobo, with the stock northbridge heatsink? can put a list?
(cos some people say certain thermalright can only be installed horizontally, and xigmatek need to bend the fins)

how many fins need to be bent on the xigmatek s1283? need to remove the spoiler? currently targeting this cos i love the S&S kit.

How to OC Q6600? I tried 9 x 400 can't even boot to Bios... is tht normal?

i tried 9 x 333 its ok... noob OCker here... can anyone teach me?
for 333 fsb how can i set ram : cpu 1:1? there is option 333/800... is that what i choose?

u might need to tweak the vtt voltage, NB voltage and GTL settings for quad core in order to get higher FSB to achieve higher clock...

eh, got new BIOS lah, dated May 2nd, 2008, major change...

fixes the unbootable Vista Ultimate 64bit (IIANM) on Q9450 ...

Newbie OC result reporting in
Hope to get some advice from the pros here.

Thanks sub_noob.
I having weird problem here.

Stress using prime95 for 5 hours no problem.
But folding takes 1 hours + to lead to BSOD.

Any idea guys?? Really out of idea already.

-pWs-

hey guys, just a simple question. are you satisfied with your board?

cause i'm about to jump to the P35 T2RS from a GA-P35C DS3R.

yeah. the NB cooler is seriously too tall. it's conflicting with my 3rd party cooler.

can't seem to get the internet working properly though.

Same bro. 

Current setting:
FSB: 415

VTT: 1.30v
Vcore: +85.0mV
SB Core/PLL: 1.75v

-pWs-

1.55v default.
But now return to stock setting to try whether is it hardware problem again.  

-pWs-

Update: Default speed also BSOD.   

-pWs-

i think i should. but the problem is that if i were to send the MB for RMA, there's a stupid sticker on the NB heatsink and the motherboard which reads, "RMA will be void if sticker is removed". so i have to live with this.
