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

Thanks, i've been eyeing up a 20" widescreen for a couple of months now, might make the jump, not sure yet.

Still on the good old 17" Iiyama!
 
WJA96

It seems a lot more stable now.

I increased the Vcore and lowered the memory. Cant remeber the exact numbers.

I still get the odd crash but its improved 60%

Cheers mate.
 
Can anyone tell me if they can use a single graphics card on the secondary slot or can that only be used for SLi?

I'm looking at getting the HR-03 cooler for my 2900XT and it would be ideal if i could use the second PCI-E slot so that the cooler wouldnt block the top PCI slot.
 
How strange!!!!

I thought I would update to the 0703 bios to see if there are any fixes to the FSB holes on the cpu.

I still got the system hang even after the update so no fix there then. The weird thing was I kept the stable 450FSB on the chip ( 3.15Ghz ) that I have had a thought I would set the vcore to auto to check what the mobo dishes out and on cpu-z it listed as 1.22v but my temps had increased by 10c :eek:

I flashed back to 0608, reset the FSB to 450 and set the vcore to 1.33v and my temps dropped back down to 32c idle again and cpu-z gives 1.328

Weird!!!!!
 
I need a bit of help here fellas....

yesterday I got my P5N-E, E2180 and 2gb OCZ XTC Rev2.

Got the E2180 up to 3ghz no problem, 300x10 (1200 in the bios), left memory at stock using unlinked. Set the timings to 5-5-5-12 1T - voltage at auto.

Anything above 1200 will not let me POST, except 1325 which will POST then hang in the bios and require a CMOS jumper reset.

I feel there's more than 3ghz from this E2180 - but something somewhere is holding me back. I'm really new to the C2D's and this 650i chipset, even the BIOS is a far cry from the old DFi S754 AMD board i'm used to so I think i'm missing something here.

Any ideas?
 
Andy my first step would be to link the RAM and then start upping the FSB from 300 and see how far you can take the CPU. The RAM won't be overclocked until you start going over 400fsb which I strongly doubt you'll reach as that'd be 4Ghz on your 2180.

Unlinked has given quite a few problems for other people on this board.
 
Tried a multitude of different FSB's above 300 and not one of them will let me POST.

Ram is at 2.1v (Linked Sync, 5-5-5-12 2T) NB 1.5 and Vcore set to Auto but +100mv enabled. USB Legacy, Micron SATA and all that are disabled too.

Given the E2180 is perfectly stable at 300x10 3ghz I'm quite frustrated that the board won't let me see just how much it's got left in it.
 
There is an FSB hole somewhere around 1200-1333 QFSB - drop the multiplier down to 8x and look for a QFSB in the 1510 area as that's well clear of any holes.
 
Will try :)

I started reading through the whole of this thread before tinkering in the bios but then realised reading 2,500+ posts was gonna take me more hours than I have.
 
what's going on here then?

Booted into windows at 1510 qfsb, 377x8, 3010mhz

CPU-Z sees it as this - everything else sees it as 471x8, 3774mhz, which would be 1884 qfsb



voltage is all over the place too - it's set at AUTO with +100mv enabled. 1.52v idle and 1.44v under load. Stress temps under Orthos mid to high 60's.

disabled +100mv and set Vcore to 1.42. Droops to 1.36 under Orthos cpu load.

Booting from the bios at 1500 qfsb, 375x8, 3000mhz still gets into windows and becomes 468x8, 3750mhz and promptly fails Orthos after a few minutes.

I'm not sure what's wrong here - is the E2180 really running at 3750, and if so, why? Or is the board just failing with large FSB and no NB cooling?
 
CPU-Z reads it properly but most other programs assume the CPU is using the default multiplier (10 in your case) so just ignore what they say regarding clock speed.
 
Dam I was just going to say 3.7ghz is really impressive. cpuz will be right I think

Try rmclock and speedfan for its nice voltage chart.


Put NB on the highest voltage and always use lots of fans then reduce it later to see if it makes a difference.

Try 425x6
 
Strange how it passes 12 hours of Orthos cpu test at 300x10 but fails it within minutes at 377x8. Both give very much the same clock speed.

I've ramped down the qfsb to 1425. CPU-Z gives 2850mhz, coretemp and Orthos gives me 445x8, 3562mhz.

Passed 10 minutes of Orthos CPU so far, temps in the low 60's with 1.36v under load.

Even Vista thinks it's running at 3.5, everything does except the BIOS and CPU-Z

Damn it!
