** The Official ASUS P5N-E SLI & Ultra 650i Thread **

oh pants,

I ment......

tCL (Cas Latency) - 5
tRCD - 5
tRP - 5
tRAS - 18
Command Per Clock (CMD) - 2t

Sorry, got carried away with the 5's :D haven't had my coffee yet.....

ok cool

RE - Command Per Clock (CMD) - 2t

it actually states auto 1clock or 2clock

ill select 2clock as i believe this is what its suppose to be

also i think i have the settings set as u put them in ur first post so tRAS @ 5 is what i have when it should be 18 lol ill reset this to 18 and not touch voltages and see how we do :)

Thanks m8

EDIT - hmmm after going in bios tRAS was indeed set to 18 so i have upped the voltage as you have said and everything boots still as im typing on the pc atm, seems like its got a little bit more life if u get what i mean :)

Will do some memtests asap, how long should i mem test for?

Also if ur ever about on msn after ive made sure my problems have gone away fancy helping with an overclock :)

Sorry about that, it probably wouldnt boot with tRAS latency being set that tight anyway. Yup, should be 18 according to corsair, it may have even defaulted back to 18 if you did indeed set it to 5.

as you asked in you previous post 2t, 2clock its the same thing.

The old rule was "1T for 2 sticks, 2T for 4 sticks " but ddr2 ram generally doesnt like the command rate being set to 1t regardless of how many dimms you run.

Regardless there is very little performance difference between 1t and 2t on these Intel platforms, and 1T might cause instability, even with 2 sticks.

If I remember correctly the 650i chipset would default to 1T (this is what AUTO sets) so yeah, make sure it is definitely running 2t by manually setting it.

Gotta be honest, I dont think I've been on messenger for years!!! spend to much time on facespace and mybook :o

Im sure I posted on this thread the settings I used for my e6600 running 3.6GHz when I used this board a while back, I will try and find them.

A 100% pass of memtest with no errors is good ram :)
 
Quad Q9550 Working ok

Hi all, not sure of its still relevant, but i just dropped a Quad Q9550 into a P5N-E sli using bios 1301 without issue.
 
Just been having a quick look through this thread and
Quads - yes standard clock basically, you can't get a quad over 3GHz on this board unless you're extremely lucky

now I realise why my system keeps crashing if I try to go above 3GHz, does anyone have recommendations for a replacement board that will be running a Q6700?
Gonna use this one in a build for my parents now
 
I used my board in a build for my brother, now running a Q6600 at stock. Always has been and still is a rock-solid board, has run 24/7 since it was new, and under constant 3-4 CPU load as well. It's weakness is for overclocking quads.

I replaced it with an ASUS P5Q Deluxe, but not because of the overclocking limitation, it was because I wanted 8GB of RAM and I couldn't get the P5N-E to run 8GB no matter what I tried.
 
My q6600 ran rock solid stable at 3GHz with 4GB of ram but that was its limits on the P5N. If you want to stick with Asus boards the P5Q Deluxe is a brilliant board :nod:
 
Nothing to do with the multiplier, this board only has a 3-phase cpu voltage regulator circuit, so your overall clock is limited regardless of what multiplier your quad has. Basically the board simply isn't up to the job of overclocking quads past 3ghz~.

Case in point, I could exceed an FSB greater than 333mhz when running an 8 multi, so it was safe to say the stock multi was not limiting the clock, the board was simply running out of juice.
 
Do yo have an R0 or M0 stepping E5200? an R0 may require the latest BIOS for the board.
Overclocking in unlinked mode may help also.

Tried unlinked - BIOS is 1403; don't know what the stepping is; will try latest BIOS...
EDIT: stepping R0

EDIT2: all sort of weird No Swearing! going on here...summary:-
1. at 1st I just swapped the CPU; listed as 2.5GHz, 12.5 multiplier fine; couldn't change FSB (BIOS wouldn't keep the changes)
2. reset CMOS (presumably always a good idea!)
CPU came back as 1.44GHz, multipler 6 ?!
Reboot#1 gives a constant m/board tone
Reboot#2 gives CPU 3GHz ?!
Reboot#3 try manual FSB increase to 960 (20%). Works! 3GHz.
Very strange. And all with BIOS 1403 (6/4/2009)

Nice job! that set-up should see you through for a bit longer until you decide its time to upgrade your entire rig.



you mean one of these...

serillelpataend.jpg


I have used one on my old p5n-e and quite a few other boards to pull off data from my old ide drives, pretty handy device actually.



Ok wasnt sure which chipsets a Serillel would work with. Not sure why its not showing the drive up for me then
 
Justa quick necro on this thread now, trying to check what bios to go for, think I'm still currently running the original from 2006 that came with the board :eek:

Just purchased an E8400 CPU so not sure what upgrade I need toget to support it? Been running with a stock E6300 for nearly 3 years now :)

I'm assuming flashing is as simple as flash .bin image onto USB, into bios > tools > asus ezflash > choose image > go

Thankies :)
 
Does 1404 have (m)any known issues, or would I be safe enough loading defaults, updating to that, clearing cmos, loading best settings and then continuing on my merry way and swapping to my E8400 when it gets here?
