ASUS P5N-E SLI 650i Thread

[r0b126]

is there a way to get windows to report the actual cpu speed at any given time? the sys info is always going to say 2666mhz I think


my machine has failed post twice now.

is setting the fsb memory clock mode to linked the right thing to do?



went back and changed it from 1600 to 1333..normal
if I do a 1333 to 1353 (20mhz adjustment to fsb), it fails post again

[r0b126]

here's a SS of what it looks like after I made the first 20Mhz adjustment in the FSB and then rebooted.

[r0b126]

here's another one...and these ram timings are completely off... i set them to 4-4-4-12 in the bios and before I tried OCing, when the machine would boot, during mem test it would even say 4-4-4-12, 2T. Why does CPU-Z report something differently?

Definitely set your fsb to unlinked. Then you can adjust you memory and cpu fsb separately. As you're oc'ing you will notice your ram will not be at the correct speed sometimes, but at 400 fsb it will be.

Let me know how it goes unlinked.

[r0b126]

changed it to unlinked...on save and exit it didn't fail post as it has been

also, there is an option to enable or disable sli ready memory
I am using 2x 1gb corsair pc6400 ddr2 800mhz memory at 4-4-4-12 timings.

What does this feature do and what is the benefit, if any, to enabling it?


ok, now its showing adjustments to cpu speed when I change the fsb while its unlinked...guess that was my problem... I also manually set mem timing to 400mhz. gonna see what happens when I jump the fsb to 1600 again

[Gauvenator]

Only use it if you have SLI ready memory. I'm not sure what it does. Something to do with ocing I believe.

What fsb are you at now?

[r0b126]

jumped it to 1600 and the computer froze when I entered the bios...gonna see if it loads windows, then reboot, enter bios and see if I can get it set back down to 1353 again and start upping it in 20mhz intervals like you suggested.

[r0b126]

ok, this is bad...its freezing every time I enter the bios. How am I supposed to lower the fsb if the bios (the very place I correct these errors) is causing me to freeze?

[Gauvenator]

every 80 mhz or so you should stress test a little. If it fails, up the vcore 1 notch and try again.

[Gauvenator]

if that continues, you will have to reset the bios with the jumper on the mobo
