3.20Ghz 1.30v (default vcore) in bios, pass superpi 32M
3.33Ghz 1.375v superpi 32M stable
3.60Ghz 1.50v in bios, pass superpi 32M
400x10, 1.50v in bios, no post. :(

wtf lol you just jumped 400mhz and wondering why it doesn't POST? :slap:

Try first 370x10, 380x10:D
400x10 32M stable it's very very good also for an X6800.

Still, I think my cpu sucks, doesn't look like mine is stable 3ghz stock volts. How fking disappointing tbh

i am wondering if this B2 stepping to correct for Raid 5 utilization has screwed the pooch for overclocking.

What i've read so far is that there's an FSB wall past 360 on retail e6700 with Gigabyte 965 boards and the P5WDH due to 1066 strap

So, this isn't a problem on other 975 boards where 1333 strap is an option?

yeh.. :mad:

I managed 3.4 with 1.55v.. seems stable but not primed it yet, only gamed for a couple of hours

(It's too long to explain and I just learned about it myself). If you want to go past that wall, you HAVE TO give up 4:5, 3:5, etc. 1:1 will take you up around 430 (333 base FSB + 100). After that you have to give up 1:1 to go up higher, but at that point the chipset will physically give up at 1.65V max. Again, it's by design. Asus went on the route to tighten the chipset timings that's why we see the fastest PI scores on this board. On the contrast, Gigabyte went on the opposite way (w/ DS3, I don't know about other models) and that's why we see such sky high FSB but their memory dividers/timings are all messed up.

If your memory is good up to 1066MHz, try running 1:2 @266FSB. It'll run like a charm. :)

The big problem is: if you select anything over ddr900 in bios, it will not even post. My ram is ddr 1000 4 5 4 15.

Try 270FSB and select DDR900. Still doesn't boot?

Tried 370X10 1.525v vCore and 380X10 1.55v vcore, 1.55v vMCH, mobo did post but crashed when loading windows. I guess my E6700 doesn't have 360MHz fsb wall, just need better cooling (currently on thermalright Ultra-120) and more voltage.

Haven't tried it yet but...isn't 365 fsb 1:1 better than 270 fsb and anything?

EDIT: OK, I tried it and I am in windows with 270 fsb and my ram is ddr 1080! Too bad spuer Pi 1m is 5 seconds slower than with 360 fsb

The wall FSBs aren't exactly set on stone. Some will go higher and some will be lower. And in theory, if you don't mind running your memory slower than FSB you can go up to 500FSB (which is 400 Base FSB + 100) And that's why you can select up to 500FSB. I've run Prime95 Small FFT @440FSB with 3:4 (memory:FSB)

Yes of course 365FSB 1:1 is better than 270FSB. (Unless you have an X6800. In that case I'd suggest you actually test each setting) What's important is neither your memory nor your board is defective. After a certain point, in order to achieve higher FSB you need to lower memory ratio. (on P5W-DH, that is)

That's exactly what happened to me. My e6600 would'nt go over 2700Mhz. Disabling Hyperpath3 must have been the last option I tried :p:

ATM, I'm trying to get it prime stable at 3.3Ghz :)

I have the same problem with memory, like every owner of this board. If i will set frequency above 950 = no post ... because i have E6600 (multi 9, FSB 420)with maximum 3.8Ghz i can use mem divider only 840 (it is great at 8-3-3-3) or 1080 (this not working).... we need fix this memory problem, i hope it is not hardware error only software, and Asus correct it in next BIOSes.

In 4 weeks of BIOS releases for this board, Asus hasn't improved the overclocking of this board one bit. I've been through them all from 0401 to current 0903, and they pretty much ALL clock equally.

can u let me know what is ur batch number on the cpu? it should be written on the box. thanks

my is 599 stuck at 3.4ghz. rams can boot at 918 max on cl5 or 4. guess we have abt the same problem

btw how to get pass 420fsb? seems like alot of people get stuck abt there.

Mine's 600 not prime stable at 3.4 1.55v :(

In order to pass 420, i had to run my RAM at the lowest divider.

I can't believe you went from 285 to 420 in one day and not satisfied. :D Also it's NOT a problem as I said, but by design. I personally think ASUS made the right decision since @400+ FSB chipset gets already plenty hot. You wouldn't want to run 24/7 much faster than that. If you want to go for higher FSB, you should find a cooler running P965 board.

And people remember that ASUS is still the highest clocking board among 975X boards. Seriously, many other boards' BIOS programmers still can't go past 370FSB justs like may of you. :D

I am now successfully running 400*9 (ran R@H over night), but needed 1.60V MCH and only the 1:1 mem divider works. Lowest divider gives me random reboots.
Now I will try to run at higher clocks, but too bad I cant set ram timings manually above 400FSB :/
It seems to work for some guys, which is quite annoying.

I am happy with FSB and CPU ocing, BUT i am not happy with my memory speed, i have great 1100+ memories but i can run them only at 800 ... it is my problem ...

can't seems to work for me. seems that 370 is a wall, 420 another wall.
