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

Well my mobo has just died during a BIOS update. Tried restarting using the crash free bios disk and all looked ok but although the lights are all on there is no signal going to the screen. Anybody got any idea if i replace the mobo, will microsoft allow me to reregister my OEM Vista 64.

Cheers

This mobo plays dead better then any Ive known, disconnect and remove battery and come back at the end of the day and try again

man you are soooo right, i should have known as ive had this mobo for so long. Updated to the 1301 bios and just got a black screen after the reboot, i threw in the CD and loaded 0202 and all looked well but again a black screen, swapped gfx to make sure it wasnt that. resigned myself to having to buy a new mobo and prey that MS would allow me to re-register my OEM Vista.
Well that was last night and after sitting here with a cuppa this morning thinking, bugger ive got 2 months leave and no gaming PC until at least a week then it hit me, ive got 4 x 1gig Geil sticks in the slots, now for that i need to up the volts which after the bios flash will be at stock. I removed 2 sticks and pressed the power button and YIPPEEEEEEEEEEEE.
now back up to 3,4 with the 1301 bios. Big lesson for me.
Thanks for the reply as well.
Just about to order the rest of my new rig for assembly over Xmas.
:)
 
I was going to say you were running 2V+ to get your 4 sticks stable, reflashing you bios will more than likely knock it back to the spd default of 1.8v.
Its aways a good idea to clear your cmos and see if it boots with the original flash and then upgrade your bios, safer that way to.

The sticks are 1.8v (stock) but i ran the NB at 1.7v so that going back to stock was probably enough to cause the issues.

Hey all currently at 3.23Ghz though not tested properly yet, only 20min in Prime small FFTs

My core VID seems to be 1.25v is that rite for an E0 Q9550? found it in CoreTemp, though if i turn speedstep and C4 State i think it is, in the BIOS, CoreTemp displays 1.10v when the multi's dropped to 6 from 8.5 (due to speedstep)

So is 1.25v my true VID? just little higher than i thought it would be.

Im running 1201 BIOS

Hi Matt,

Can you share exactly what settings you are using the BIOS to obtain a stable overclock with the Q9550? Or perhaps anyone else can share what they use. I've been dying to overclock mine and squeeze more performance out of my processor on the P5N-E. After paying nearly $100 for a MaxOrb CPU fan it would be a shame not to overclock it. :)

The multiplier on the Q9550 is 8.5 which is only .5 more than the Q9450 that I read you guys obtaining good overclocks on. Would the motherboard be able to handle a 1500 FSB OC better with an 8x multiplier for example? I'm still fairly new to in-depth overclocking so any help in general would be appreciated.

Thanks for any tips.

Well I got the system to POST with a 1642 FSB and a 821 Memory clocks (just to hit that 1:1 Ratio). Seems stable until I started gaming, it would restart shortly into it. So I'm assuming it's unstable, the board does indeed have a lot of FSB holes, doesn't do anything past the splash screen at 1500 or 1600 FSB. I've lowered it down to 1620:810 and I still get sudden restarts when gaming about a minute or two into it. It's definitely not a temperature issue since I have a MaxOrb CPU fan, and my room is very cold right now (have the window open).

Any suggestions to make it more stable? I didn't mess with the Vcore at all, it's at 1.392 V (Auto in BIOS) according to CPU-Z which I believe should be fine, but maybe not. I can't get the system to do anything at all on 1600, 1500..1550..etc. It's very picky about what it accepts.

I tried both 1.5V and 1.7V on the NB and it was still unstable. Actually seemed more unstable at 1.7V, got a blue screen shortly in and it would not let me get into the BIOS at all after that. Had to do a CMOS battery reset to get back into it. I think I'll just stick at stock speeds for now until I decide to upgrade the MB. :P
 
Does anyone know if the Zalman CNPS9700 NT will clear the stock NB heatsink fins? If not, are there any alternative NB heatsinks that will allow it to fit in? Currently the Northbridge is operating with the same settings as when the system was first used.
 
im glad i found this topic i put a 9450 in a p5ne sli on my first pc build after not researching properly. i saw 45nm after bios update and supports 1333 and thought it would be ok.

I am having a few problems, before i clocked my ram and front side bus to a 1:1 ratio 667 ram with 1333 fsb rather than 800 mhz ram it was rather unstable and would crash prime 95 within half an hour and gta iv would crash within half an hour and crysis would bsod occasionally. now prime 95 and crysis havent crashed since and gta iv has only crashed once since but hey that is gta on pc were talking about.

Has anyone else experienced any problems wth the p5ne-sli and the q9450 they havent been able to sort. i find my pc freezes up occosionaly for a second before continuing regardless of fps or how resource hungry the game is but that could be anything. there has to be some reason 45nm quads aren't properly supported by this board i'm strongly considering swapping out the board regardless just incase.

Something like voltage phase control, this board has like 3 phase and others have 5 or more. It is a budget board and 2 years old now, theres been lots of bios updates so maybe they help
