Asus P5B (vanilla) Overview

[|SiLA|]

That look stable. Now play a little bit to find the real limit

going to play tonight
it's too damn hot here in rome today lol

anyway that pcie @110mhz helped

[|SiLA|]

anyway guys i need help

what i can use to increase fsb and voltage on windows?that asus ai suite is total crap

[CrappyLuckMan]

If you have enough cooling can't you just max it out in the bios? Or do you want to save a few cents or something by lowering the voltage when you don't need it. Btw, what the hell is PCIe frequency? I can find AGP but can't find pci-e defualt frequency.

[|SiLA|]

well looks like this crappy mobo need a lot of vmod

i've set 1,68 on bios and i get only 1,5 full and 1,52 idle
i need atleast 1,6 for my cpu prime'n atm 470x7@3,2ghz

[|SiLA|]

does clockgen works for this mobo?

[|SiLA|]

i'll wait around 30/40 mins then i'll go higher

[Professor12]

Yeah the vdrop on this mobo is insane. I see at least .1 volts and sometimes more under load. It is also distressingly flaky. I thought all was well and good but today it has been crashing/rebooting randomly again.

[CrappyLuckMan]

Yea I'm getting 1.58v from 1.7v in asus probe. There is something in the bios that says if you boot with lower voltage it will guess that you cpu shouldn't go much higher. I think I tricked it once, I posted about it before.
"When U boot with windows at auto vcore and 266fsb then change it to 1.7v it will show 1.48v on probe. If you boot at 385fsb and 1.7v into windows the first time you can get probe to show 1.6v. I think the bios has some kinda AI (though I did turn it all off in bios or I couldn't even go past 320fsb)."
So if you have a lot of time on your hands, clear the cmos, and set the overclock on first boot, boot into windows and see if anything changed.

[|SiLA|]

here's 470 now i'm running at 500x7

[|SiLA|]

error after 5 minutes at 500x7@3,5ghz
pcie 110 vfsb 1,45(max)

[|SiLA|]

more updates

dual 32mb spi @500x7

[Vric]

woot.. 500Mhz FSB !

[|SiLA|]

woot.. 500Mhz FSB !

yes

finally i'm in the 500fsb dual 32mb spi stable



i've tried 520..no post...510..no post

so the limit i guess is between 501 and 509

using same settings of before..

[Vric]

Will wait next bios. 100Mhz increase in one update isn't bad at all.

[|SiLA|]

Will wait next bios. 100Mhz increase in one update isn't bad at all.

not for me

140/120mhz more

i just hate the vdroop it's too much..and the vdimm

my d9 is wated on this mobo

Congrats on the success and 500 fsb Wish I could say the same but I finally decided I had enough @%!(ing around with that bios and reverted to 0211 which is working splendidly. The bios was flaky at best and would cause random crashes and reboots during video intensive things. I couldn't play WoW for more than five minutes without a windows system lockup or application crash even with orthos running merrily along in the background. High fsb was a crapshoot, most of the time crashing before windows initialization even with loose timings and comparatively low overall cpu speeds. I would venture to guess that Asus tweaked certain elements of the pcie bus with this bios and that is perhaps what caused the instability that I and others have experienced. Hope the next bios fixes some of these issues.

all i can say is..check yer vcore..set vfsb at 1,4..set pcie o 110mhz tnx to this i went over 470fsb and reached that 500

since can't have more than 1,5 real vcore here..running my 6400 @3,6 450x8 with 1,46vcore in full

[CrappyLuckMan]

Hmm I'll try 1.4 and 110 pci-e x16, though you really think theres a difference to 1.45v?

Nope, didn't do squat. I wish there was an auto feature for the extra ram settings I have no clue about, maybe that's why I can't run super pee at 900mhz ram stable.

[Vric]

did you try by SPD ? I also have no cluw what are most of the new options

[sparks]

I have p5b deluxe and have a LOT of problems with it and a 6400 processor.
I can't figure out if its the cpu or the mb.
2 gig of HZ gskill memory and ninja cooler.
Fresh install it ran ok. OC to 333 fsb with only a little bit more cpu voltage.
BUT the temps are high.. 48C idle and 58C with prime running.
Well I am thinking all kind of things but why this how...damn
So I go back to stock settings idle at 45C and max temp is 54C

SO I got crazy and wanted to see how high it would go, oc and temps
so I ended up at 1.435 volts on cpu and 2.1 on memory and 410 fsb.
MAN this thing is great but temps were way high.
53C idle and 62-63C with 2 primes running.

well let me go to stock and check temps and stability and see...everything runs
ok...can even undervolt to 1.15 volts and runs fine boots into windows but a little unstable.
but it was just a test for low temps and I get 34C in coretemp with this voltage and all stock.

NOW is where the weird begins.
I can not go higher than 300 fsb no matter what I select.voltage and memory I believe I could select
the highest on the chart and not get it to boot into windows.

IF I had not gone to 410 with this setup and hardware I would just say
oh well lemon processor and just my luck.

|SiLA| is there any chance you can post screenies of your bios settings or tell me what I have to set to get back up to oc speeds.
Its beyond me how I got there. This makes no since to me at all. anything over 300 and it won't do even get into windows.

thanks for any help pointers or flames this is driving me crazy

[|SiLA|]

here's my new daily..vcore on full around 1,46 and 1,47

[Vric]

woot.. 500Mhz FSB !

Going downward ?

We want 550 !

[|SiLA|]

Going downward ?

We want 550 !

lol u already edited

i was going to ask where is that 550fsb

i'm looking atm for my daily use

[CrappyLuckMan]

wrong thread sparky. Yea, I think when I select by spd it goes to 666 timings which is slow.
