maybe someone has an idea to solve this problem. or I just keep trying with different settings.
btw my P5W has the newest bios 1101

hmm ..seems that people with high fsb get much pain to keep their rig stable under dual prime :(

It is likely a heat problem. If I leave my vMCH at Auto, it'll crash if I don't point a fan at the nb/mosfet sinks. If I bump it up to 1.55 V, no crashes :)

Is speedfan accurate with Vcore readings ???

Running orthos for 7h39 min asus probe reading 1.44/1.45

If yes that infamous Vdroop not only temps ( 54° actually , not so bad IMO !).... damn asus boards :mad:

Buy a digital multimeter and find out yourself :fact:

So would the posted memset tricks work if I can boot up at say, 400 (for a 3.6 ghz OC) WITH SPD on but cannot get it stable at a lower voltage?

well my P5W DH is up and running from bios so far 22.5C cpu temp and 30C mb temp water cooled cpu heh

Still 1.02g rev it seems but confirmed that the 1.85v MCH option is available - funny it was set to default 1.85v MCH when i loaded the bios for 1st time :eek:

This board came from Asus direct and is using default 0801 bios that came with board :)

is that 1.85Vmch gives you an extra Mhz of OC?

so this 1.85vmch option is a hardware revision and not bios enable? I have the 1.02g too but it doesnt have that option.

Anyone have a weird issue when you set your PCI-E freq to 101 in the BIOS but it shows up as 80 in ClockGen?

BIOS 0801

BIOS 0801

yes i thought i was the only one

I actually try to adjust it to 100 thinking that's maybe the reason why I was unstable; well it crashed on me..:(

P5W DH only been running for less than 3hrs havent even installed windows yet.. just doing my usual memtest tests first to figure stuff out :)

mines 1.02g so i don't think the change is major enough to warrant a revision change i think .. not sure

one question i have regarding this so called 360-370fsb wall.. what is the wall related to ? as in is this wall in booting P5W DH, stability, or benchmarking etc ?

I'm currently memtest at stock AUTO = 1.242v vcore with 9x380fsb 1:1 4-4-4-12 at 2.1v for 3424mhz with my E6600 (yes probably won't be windows stable but this cpu managed 3496mhz at 1.242v on my bad axe windows benchable).

So question is where's this fsb wall meant to be at in what apps or scenarios ?

My southbridge temp is jumping by 15c when I start up 3d apps. looks like my Crossfire setup is dumping a load of heat on top of it. Do you think its worth sticking a fan over the area?

I guess in my experience the "wall" refers to stability. Probably dual prime or orthos would be the obstacle. While the actual freeze or instant reboot wall is around 415-420 running benchmarks.

Have noticed the same...I have changed the FSB with Clockgen and it reboots on 415FSB or more...even with ram timings @ SPD...:slapass: Any tips for boot in 430FSB or more :rolleyes:

I can get a boot at 440FSB, not tried for stability but when my E6300 gets here I'll be happy with 428 * 7 :)

I dont get it.... I see people posting about 400FSB+ Can you guys be more precise and tell us how u achieved this? Only way i get 400FSB+ is by settings auto SPD timings.

I can boot in and be fully stable @ 414mhz but as soon as I set the fsb to 415 through bios it wont even post. If I set my memory to spd I can boot in up to 425 but and bench but as soon as I try 426 It wont post.... tried upping all the voltages and its same thing. The only real thing I did to get over 400fsb was to disable hyperpath3 its getting over 414 thats been the challenge for me. this is on a o.e.m 6700 havent played with any of the multis under 10x though think I just need more than 1.65mch to go higher from this point.

Allright m8 thanks for the info....That being the case its most likely the crap mem-dividers on the board.

should have mentioned this is @ 1:1 when I try other ratios over 410 I dont post either. Havent tried them all as I keep getting pulled away from playing with my rig the past couple weeks :(

Hehe look at my beauties!!!

First my Ninja ;) Really hard to lap something so BIG o.O

http://img132.imageshack.us/img132/4651/dscf0012hf8.jpg

Have you ever seen a lap job better than this? I haven't, very pleased!!! :D

http://img148.imageshack.us/img148/3...dconroegh6.jpg

Funny thing is.. before I started lapping my ninja I dropped my Celeron D backup cpu onto my hard wooden floor. It landed bang on the corner of the substrate and I got some big dogeared corner on the substrate. I was like Oh oh.. BAD START.. should I really lap my Conroe now :eek:

I thought no way is this cpu still alive... Plugged it into my P5WDH and it's running windows perfectly right now rofl :D STOKED!!

where can i get the newest bios from (v1011)?

It's 1101, not 1011. ASUS.com

Hey, I did a little more testing. My CPU is stable at 3.2 GHz (357 x 9) 1.40 vCore in Orthos - Blend mode. If I switch to 400 x 8, the system is no longer stable. I've tested up to ~375 FSB without it failing.

I'm quite sure the CPU can do 3.2 no problem as I've done Small FFTs overnight.

I've tried 1.65 vMCH with loooooose RAM timings, as well as 1.20 on the SB (I forget the voltage name haha!) as using my thermal probe (index finger :)) the SB was burning hot to touch under my two 7900 GTX's... both with no luck in increasing 400 FSB stability.

wow lawrywild, nice lapping wish i had the patience to lap for that long to get it shiny like that heh

Seems to be about the same as on my Intel D975XBX when @3600mhz at 1.376-1.384v vcore load (Badaxe needed 1.371v vcore) but with P5W DH needed to raise MCH volts from 1.55v to 1.65v :)

vCore = 1.425v
fsb = 1.3
vdimm = 2.1v
MCH = 1.65
ICH = AUTO
