my impressions of P5B vanilla so far with E6600:
for starters, i had hard time to boot up and run a 1M at the same speed the same cpu was running on p5wdh 24/7, that is 380x9 (1:1 mem 2.1v)
Actually 380x9 was the max i could make with this mobo.
vcore is usually 0.08-0.09v lower than set from bios in idle and another 0.02v lower with load. 1.7v (1.544v idle) was too much for it.
tried to find fsb wall with 6-8 multipliers, 410 failed orthos and 415 failed 1M.
405 was at least 30mins orthos stable but failed dual 32M :)
atm running 400x8 1.6v (1.504v idle real).
tried different mem timings and speeds with no luck.
another note - PEG force x1 should force pci express to x1 speeds but in reality it makes system unpostable and needs clear cmos :)
also - PCI latency setting doesn't work at all, thus making my soundscape mixtreme soundcard nonfunctional.
What are you using for cooling?
It would have been a killer board with raid. I bet they just disabled it for marketing reasons. Since the delux version has raid.
water for both cpu and NB.Quote:

btw, that "false start", i think, is when the board sets the multiplier.
when i had the "change ratio" enabled, then it always did that..
humm I will see if I left it Enabled (I tried it, it work, but I set it back to 9x)
I'm nearly sure I disabled it.
There is a lot of potential with this board and E6600.. I can post at 8x400 VERY easy, but my memory is totally unstable at this speed. Didn't tried more because of that.
Until I find a way to make the OCZ Platinum memory to run correctly in 1:1, I'm stuck under 3Ghz.
Caater what ram use gots?
g.skill 6400 HZ with micron chips..Quote:

I was really worried I wouldn't get a good OC and end up not breaking ~330 FSB.. I'd be happy with with 360 x 9 or 400 x 8. My ultimate hope and dream is 400 x 9 hehe.
you'd might wanna buy e6400 instead of e6600 with that mobo ;)
clock-for-clock, besides spi times, there's small difference 2M vs 4M.
and allendales are proven to be nice overclockers on P5B.
that was a little suggestion.. because now i'm back on P5Wdh and running my e6600 at 3.5ghz.. the speed i wasn't able to POST on P5B :)
no need of 3rd party chipset cooler. just get yourself a 50mm fan and put it over it. Remove the bubblegum stuff they use as thermal paste and put some AS5 and your ready to go.
Temp dropped A LOT by doing htis (over 40F)
what is the WR fsb on this mainboard ?
517 I think.
Please Help me ! friends.. asus p5b and e-6300.. bios 0309 but not 333 and up fsb.. ram is micron d9 (spectek) ddr2-667.. no overclocking help me.. :(
(import. asus vento + psu 300w , vga x300se)
Your PSU at 300W would definitely be the problem. Did you looked in the manual ? It say 350W minimum (and even there, it's damn short for overclocking)
Having issues to overclock a E6600 + P5B non deluxe...
My setup :
P5B non deluxe
E6600
Aerocool GT-1000
2x 1GB Crucial PC6400 (4-4-4-12)
Zalman 460W PSU
other bits are : 1xRadeon 1900XT 512MB, 2xSATA drives, 1xATA drive, 1xATA DVD writer, 1x Creative Labs Audigy ZS, 1 Belkin Wireless network card
I have the latest 0309 bios on my motherboard and I've got problems to overclock this damn thing past 330.
I have tried :
- upping the Cpu Vcore to 1.5v
- FSB to 400mhz as recommended by some
- Disabled Spread Spectrum
- Disabled legacy USB
- PCI Express @ 100
- PCI clock @ 33.3
..
but it will just lock up, system will do the two phase boot (power up, down and up) but then locks up with numlock key on.
I tried putting Vcore up to 1.6v that didn't help, upping Vdimm to 2.1v didn't help either.
what are your temps ? I didn't had problem to boot at 333x9, but memtest failed (I have memory problem) I even tried 350x9 and 400x8. All of them post with 1.35V, but memtest fail again.
Ok, I used this motherboard for the first computer that I built, and after getting the parts, RMA'ing incompatible RAM (pqi Turbo 1GB 800Mhz), getting my corsair stuff, and getting windows working, PC Probe is giving me a reading of 56 degrees Celsius on idle. It was more but that was before reseating the stock heatsink/fan and changing the CPU fan to performance mode in BIOS. Despite being the noob that I am, I am pretty certain that thats way too hot for an idling CPU without any OC'ing. I am not even trying to OC with this, all I want is to simply cool it down. Any suggestions?
EDIT: Well, I know I could use some arctic silver and a better HSF, but for now I am looking for suggestions that don't resort to new hardware.
As advised from somebody in this board I tried to boot up from 380 by setting multiplier at 8. Tried setting Cpu vcore to 1.4 and other various things upped, machine would boot up but randomly crash during Windows startup.Quote:

Currenly with Core Temp both my cores are showing at roughly 48 degrees C.
Running SuperPI 2M now and temp goes up to about 54C.
I'm going to try booting up at 400x8 setting up Vcore at 1.5v+
it could be a memory problem too. try memtest86+ before booting window (this is the first thing I do when overclocking.
Right..managed to have the machine to work at 400*8 (somehow Windows said it was a 3.6ghz instead of 3.2ghz, I wished!..).Quote:

Problem is Cpu temp is about 55 using an Aerocool GT-1000.
Machine was stable for a while but running intensive applications (Super PI+Prime95+playing HDTV content) would crash the machine in a matter of minutes because cpu was getting too hot at about 60+.
Would anyone know if a Tuniq Tower 120 would cool this cpu to acceptable levels like 50c idle ?
Cheers
Has the issue with FSB533 CPU's been resolved?
Don't run it constantly at that voltage, you'll eventually kill your chip that way.Quote:

No it doesn't, there is quite a mismatch between the P5B bios setting and what I read in CPU-Z. Can't remember for sure now what was the voltage required to push above 3.2ghz on the E6600 but it was I am pretty sure in the highs 1.4vQuote:
