How much of an increase in bandwidth/performance are you seeing with 4:5 vs. 1:1 ????
Could you let me know step bt step what you did? I got to 3360Mhz but then it crapped out. All I'm doing is going into the bios. I'm running OCZ 2x1G Gold 5-5-5-12. Still messing with the P5 board did the most current bios. Still staring at the ECS P965T-A Board with E6600 CPU but havn't cracked it open in hopes that the ASUS P5B-Deluxe board and E6400 can get to 3000 without crashing. Is that to much to expect? 8x300=2560 Mhz is the most stable I can do.
guys, i'm also having trouble with my oc..
i've used many boards before this board and i can say other boards work greater to me!
dq6
max 14hrs prime stable @ 1.38vcore 3.15ghz 350x9
biostar 965p
max 14hrs prime stable @ 1.38vcore 3.2ghz 356x9
asus p5b deluxe
max 14hrs prime stable @ 1.425vcore (bios) 3.1ghz only! 345x9
then i read some guys said this board having trouble from 340-400.. so i flashed to 0507 and tried 400x8 also failed prime.
and ok done with cpu clockspeed.. now for the ram dividers.
i've used my ram on ds4, dq6, and biostar 965p deluxe.. all are tested stable using divider up until 1088mhz 5-6-5-15 @ 2.2vdimm..
but with this asus, even 1000mhz also failed after 20secs in prime!
summore i cant use 4:5 divider..
i tested 400x7 (2.8ghz to avoid cpu limitation) ram @ 1000 and failed memtest..
can u guys help me out? i used all the bios from 0502 (originally came with this board) and 0507, 0609..
i cant seem to OC my board with the e6400.
as the previous owner could do 500+ FSB with my board then i suspect 2 possible sources of the problem:
* the PSU fortron BS 500W that has only the 4pin plug (though the motherboard has a slot for 8pin)
* the ram with inifeon chips.
i get to try ram with elpidas today. if those dont fix the issue, then its possibly the PSU?
You need to go past 400.Quote:

BIOS 0614 is now officially on Asus' ftp, though it has the same checksum as the 0614 version that has been circulating.
i tried 401,402,403, 404 and 405 also same thing happened. it seems like this board doesnt like my ram which is absolutely a great performer on gigabyte boards & biostar.. :(
i cant have stability with 4:5 divider! but 2:3 can run prime eventhough it will fail everytime my ram reach 1000fsb.
Same board and RAM here and can't really get much past 330 FSB before things crap out - starting to think that the OCZ RAM doesn't like the P5B even after the BIOS fix for it - plus mine were RMAed and replaced/reprogrammed to work with the older BIOS that were originally incompatible with the OCZ2G8002GKQuote:

Description P5B Deluxe Release BIOS version 0614
1. Support DDR2 double side x16 module
2. Enable support for CPU ratio adjustment on Kentsfield B0 stepping CPU
3. Enable conroe/kentsfield ratio overclocking higher above default value
4. Fix CPU Fan profile mode not correct after system shotdown
5. Enhance memory compatibility for DDR533 and DDR667 modules.
6. Revise S3 fuction not stable when CPU FSB over 300MHz.
7. Enable support for OCZ2G8002GK-6400
8. Fix PCIEX1 will disappear after update beta bios from 0405 to 0507
9. Fix some lock cpu will show "modify ratio "item in bios(ex:660-SL7Z3 3.6GHT PSC800 2M/EM64T 002)
10. Fix some lock cpu frequency not correct when lock free fuction enable(ex:660-SL7Z3 3.6GHT PSC800 2M/EM64T 002)
11. Fix kentsfield L2 cache not correct issue (in bios setup)
12. Fix SATA configuration select disable and compatible mode, and BIOS still show SATA5 and SATA6
13. Update ICH8 Raid option ROM from V6.0.0.1022 to V6.1.0.1002
14. Update Marvell 8001 and 8056 Lan option rom from 5.16.3.3 to 5.17.1.3
i tried the elpidas and now i could run 300MHz FSB smooth, but 401FSB doesnt even post. could it be the 4pin PSU, should i get the 8pin?Quote:

as I have written above, I updated to bios 0614, changed NBv from auto to 1.45, and wooha changed my fsb to 420! and it worked great, no problems... I have now dropped down the vcore to 1.35 from 1.41, and it works great with lower temp, but I don't know if I will have to change back to 1.4....Quote:

everybody who has the problem with e6400 and p5b and wants to get a proper help from this thread, should write down exactly what settings he/she has in the bios...vcore, vdimm, NBv, timing, divided or not, what is enabled and what disabled
but here I have one issue too.... I am not able to change the multi to 9, the bios doesn't accept it! the same was in bios 0507... why is that?

Check the AI Suite vcore and go by that.

does anybody run their P5B only with the 4pin (2X2) additional P4 power? i am running and i wonder if my OC-ing is hindered by not using the 8pin additional power.
it isn't an issueQuote:

My board came with a black cover over the additional 4 pins so I just plugged the 4-pin in.Quote:

should we take it off though? i also connected just 4 pins and left the black cover on the other 4..
is it better to remove this cover and connect another 4 from the psu?
EDITED---
Woah I thought I didn't have 320-399 anymore with bios 614 but now when I set to anything above 321 in BIOS by the time it gets to Windwos CPUZID is showing 321. SPeedstep and C1E are disabled. Vcore 1.35, vram 1.9. BIOS boot-up screen also shows 2.66ghz (321x8).
E6400, Corsair DDR 6400 (C5)...
This is well and truly not good.
I tried adjusting in Windows with ClockGen and the system reboots.
Well now I managed to use ClockGen to get to 400x8 in Windows. Passed 2m SuperPi. Running a little Orthos now...
But if the BIOS settings don't stick, yeeesh!
-edit
After three good passes in Orthos the computer just rebooted without giving an error. So much for 614!
If your psu has an 8pin connector then u can remove it and place the other 4pin.Quote:

BTW why this thread isn't a sticky? :confused:
Is this normal,my friend have Ga 965Q6,and with same settings (CPU 2433Mhz,memori 900Mhz(4-4-4-12)he have 6000m/s in Sandra 2007(memory read),and i with my P5B DL- 5600m/s.
Intel C2D 6600
P5BDL,Ga 965 Q6
Kingston 900Mhz 4-4-4-12
bios 0614
:confused: :confused: :confused:
Well, not a mhz increase more for me. Damn RAM is crapping out at 450mhz, yet I can't do 500 @ 5-5-5-15 on a 2.3v but they're great at 4-4-4-10 450mhz, what the crap? aaaaaaaaahhhhhhhhhhh, this RAM is killing me.
Anyhow, there was a trick on some feature in the timings section which is the "Static Control Read" and previously I had to set it to diasble to boot at 300fsb on a 2:3 ratio, so now I don't have to set it to disable but meanwhile the 450x7 just works as it did with the previous BIOS.
Kickass BIOS nevertheless.
Although, I updated the BIOS through the ASUS Update software, when the BIOS were flashed, I got the message saying my PC will need to restart, well it did but......it never came to, just off. So I turned it on again and it reset the BIOS, of course and then came the part of settings things back, what a pain that is.
Screw it, I'm selling my XMS2 800EPPs and getting the Corsair Dominator Series TWIN2X2048-8500C5D 2GB Kit DDR2-1066 PC2-8500. What do you guys think?
That has happened to me with every flash I've done. Very scary the first time it happened.Quote:
