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

[silversurfer]

I checked my 24 pin cable though I didnt manage to unplug the dam thing because everything in my case is wedged in. I have all the cables there but no doubt some are not being used.

You can get power calcs to check if 450w will be enough. I use an aerocool 450w and its enough but I have just a 6600gt not a 8800gtx

mr google says

These calcs tend to be conserative imo, not all of your system will require max wattage all at the same time but it does pay to play safe

Fair enough. What about the buzzing noise though? It started when I actually started playing, so I guess when the 3D card was under heavy use.

I got this board last week and had a faulty one at first! anyway get the second one today and get the same problem with my 4300 seated.

It will power on and then off within a second. I spoke to tech support and they believe its because the bios version might not be compatible with the 4300.. any one using one fine out of the box?>

 

[silversurfer]

Are you using sli at all. Have you changed the position of the selector card and where is your graphics card placed on the motherboard.

If in doubt, simplify it all as much as possible.

Double check there isnt any shortcircuit at all, Ive accidently shorted the motherboard out on the case by accident in the past. Or I placed a screw in the wrong place where there was no hole on the motherboard, could be something simple hopefully.
I cant say about the 4300 but I thought it was compatible

 

[mattpj]

Thanks for reply,

Not running SLi, i have had two of the same board, and even if i build out of the case it gives me this grief also.

I haven't touched the selector card either :|

 

[silversurfer]

I guess you cant try different cpu, memory and gfx to see

 

[mattpj]

occasionally it will power up, like the other board deemed faulty, when it does this it will NEVER post. I get nothing on the screen either, whether I have a a x1950pro in there or my spare PCI old riva tnt which i know works.

Its left me stumped, OCuk are saying i need a bios flash!?!?!

 

[mattpj]

I dont have spare CPU or mem to test unfortunately..

 

[silversurfer]

They would know since they have all the parts to test. Ask them to loan you a celeron for the flash

 

[mattpj]

I live near to overclockers so they have offered to do this for me, if only i hadn't sold that rubbish p4ht for next to nothing

 

[tereu5]

I saw here that Tuniq works fine on this mobo(P5N-E Sli)
but does any1 got this cooler
Noctua NH-U12F

It fits without problems??

I have to say I like this board, even with the vDroop.

With an E6400 and Team Xtreem DDR667 3-3-3-8 RAM, I'm just running a quick test @ 325Mhz FSB = 2.6ghz. Running prime95 for 13 hours now. All stock voltages except northbridge @ 1.35v or something (haven't tried lower).

Really quite good at how it recovers from failed clocks too. It didn't like 350mhz FSB at stock giving me 2.8ghz but that is probably the CPU or something saying no.

 

[SpudMaster]

how bad is the vdroop?

 

[smids]

Well at 1.300v (manually set in BIOS, which gives pretty much 1.30/1.28v unloaded. This drops to between 1.28v and 1.26v when dual prime loaded.

 

[tereu5]

Ok so I place an order....
about this vdrop basicly what i will have to do later is add some V in Bios and that will solve the issue? And this Vdrop occures in some stability problems or not?
oh and any1 use this memory with board,
http://www.overclockers.co.uk/showproduct.php?prodid=MY-017-GS
any problems or else related ?
cheers

 

[silversurfer]

It doesnt solve the issue, its to compensate for less v when you most need it. In my case I set the voltage 0.07 higher then I actually require it because thats how much it falls, it means higher idle temps

 

[SpudMaster]

ah right, seems similar to my ds4 then. i got 1.4125 set in the bios. cpuz reads at 1.392 and its drops to 1.376 when running small ffts in orthos

I put together my system on Friday evening with a 4300 and it fired up straight away without any problems, with the old November/December bios. So if you have had 2 boards and not fireing up with a 4300 my guess it must be some other component thats being faulty.

I was thinking of running this board with a mild overclock of either 266 or 333 fsb (most likely 266 at least to start with) it started up fine at 266 without changing any voltages beside changing the RAM to 2.08xx something as it was the closest to the 2.1 specified on the sticker.

I did get an IRQL message after a while in Windows so my guess is that I need to give it some more juice somewhere, any of you gurus have an idea on what? I was thinking CPU but there might be some other ideas.

All in all I'm happy with the system and changing between WoW and desktop hasnt been this smooth before, gotta love dual core

ok but is that a big problem? i mean if cpu's got less V it's crushes(blue screen,reboot) or someting?

its not a big problem and a lot of boards droop. it just means that u might need to use a higher vcore when overclocking to get a cpu stable compared to a board with little or no droop. Ambient temps will be a bit higher to
