*** MSI P6N SLI Platinum OVERCLOCK 650i ***

[Assimilator1]

Maybe its just the limit of your CPU?
Whats the vcore at?
Also what do you call prime stable?

Is the 12v line reading ok under load?

 

[imported_Planatoid]

It'd do 12+ hours of Prime just fine. THE vcore's at +.0375. The voltages read just fine, even with a multimeter.

Nevermind, it's not that stable, it only lasts for about three hours. But still, I'd like some more voltage on the NB and it's extremely annoying.

 

[imported_reboot]

Excellent thread. I have my E6750 @ 3.0GHz with the settings described. Seems stable, but of course, I need to run Orthos for an extended period of time.

 

[Assimilator1]

Sounds good ,& welcome to AT forums

Planatoid
You need to run Orthos for at least 24hrs to be as certain as possible ,I've had it fail at about 18hrs before ,twice on 2 different rigs.

Like yourself I'm somewhat confused as to why your mbrd won't take higher NBv ,maybe it's got something to do with your quad core CPU putting a heavier load on the NB?? ,also quad cores generally don't overclock as high as dual cores.
Sorry I can't be of more help.

Btw did you test the voltages whilst it was running Orthos?

[Assimilator1]

Linked means synched to the FSB (or close to anyway).
Manual is as it says ,you can type in the speed so it could be asynch or syched depending what you've put in.
Auto just sets the RAM speed to its default via SPD.

So if the RAM is set to auto you can raise the FSB & not worry about the RAM being overclocked.Then your o/c ceiling will not be limited by the RAM.

 

[imported_Planatoid]

Yeah, I'm not too concerned with how stable it is right now, I'd just like it to boot. I'm pretty certain the NB voltage is holding me back, so I need to solve that first. And it doesn't make sense that it wouldn't use more voltage, more voltage should only make it more stable, not less likely to boot, but more likely.

Also, I think I may have solved some people's problems. From what I was reading, people were having trouble, for sure, flashing their BIOSs in 64bit Windows (happened to me) and perhaps Vista as well. So, I wanted to downgrade my BIOS to 1.3 to see if it'd help, and saw that running LiveUpdate with v1.4 put some temp files in a folder. So, I found the folder, deleted the 1.4 BIOS, put the 1.3 BIOS in there, and ran the executable and it worked like a charm.

[Assimilator1]

You used live update??:Q *shudders*
That reminds me ,I still haven't updated mine to the latest bios.

I don't get your problem either ,usually if a component becomes less stable with more voltage it's because its either getting too hot (not enough cooling ,but IIRC you have a fan on your NB & plenty of case cooling fans too so it can't be that).Or its because the PSU is at its limit & raising voltages is taking it beyond its limit ,however (IIRC) you've tested the 12v lines (& others?) with a multimeter & they checkout ok, so it's not that.
1 other thing that can happen on the rare occasion is a component just doesn't like higher voltages ,period.I once had an XPM 2400 that was a very poor overclocker & didn't like any increase of vcore over std desktop voltages.I know we're not talking about a CPU for you ,but it maybe the same affect your NB is suffering from?
Unless someone else has other ideas?

Btw has anyone managed to run 1T command at high FSBs?

I had a quick stab at running that yesterday & even increasing vRAM from 1.95v to 2.05v didn't get it stable ,crashed Orthos in less than a minute ,the increased voltage made no difference.Maybe the NB needs more volts? if so then that's a no go-er as its as high as I want it to be already.
My RAM is OCZ 6400 Plat rev 2.

 

[imported_Planatoid]

My RAM doesn't do well at 1T at all. It might boot into Windows, but it'll BSOD pretty quickly.

 

[iluv2fly]

I have not had any luck with 1T. I have tried it up to 2.1v.

It lasted for about 5 minutes then the computer locked up.

I use OCZ 6400 Plat rev 2.

 

[ELicious]

Is this a decent board for a q6600? I'm getting a B3 chip and it will be watercooled. I'm hoping to hit 3.3Ghz.

Did I mention that + 1 notch of NB voltage=stable/unstable computer for me. I have it on 1.325v and anything lower than that, I see instant freeze. Now I've passed 12hr orthos, 12 hr memtest. Used the computer for over 1 month with the new setting and 0 crashes, so it's up to u.

 

[h4x0r]

I'll be getting the last of my rig this week and will post some results when I can. Been a while since I OC'd much...is there a good place for a guide on OCing the P6N? Mainly since I've been out of the loop a bit, I'm not up to speed on some terms (1T/2T?) and what they mean...thanks!

I have a Q6600 with this board.
The best I can do is overclock till 3Ghz.
It runs pretty stable.

But when I do that, my systems reboots it's self after "post" several times before it gets into Windows!
When finally Windows loaded, everything works fine!
Ran Prime95 stable for 3 hours.
When I turn off my PC and wait a few hours to turn it on again. It has to reboot several times again :S
Sometimes it hangs right before the Windows Logon and I have to reset the PC.
As I said before, once in Windows, everything works fine!

Does somebody know what is causing this problem?
Or has the right settings for a Q6600?

I'm using these settings in BIOS:
FBS: 1333
MEM: 800 (stock)
MP: 9
CPU Voltage: 0.1375
MEM Voltage: Auto
NB Voltage: 1.35
SB Voltage: stock
FSB VTT Voltage: 6%
Spread etc.: disabled

Thank you in advance!

[iluv2fly]

Try this!

Shut down your computer. Unplug all Usb/firewire/external devices. After restart reconnect everything again. You could have an issue with your irq's.

I know it sounds to simple but it worked for me, I had a similar problem.

 

[Akuma2000]

That didn't work.

But I guess I found the solution.

I had my NB set to 1.45 en VTT% on 4%

I've changed it to:
NB: 1.3
VTT%: 6%

And it seems to boot fin now.

Don't know why this works, but it works so far

But I do get Blue Screens once in three hours or so...

 

[imported_Cynosure]

I've been having a lot of the same problems

I have an MSI P6N SLI-FI mobo (not the platinum) but there is no real support thread for that, so I've found my way here.

I occasionally get random restarts even with the restart on error option disabled.

I get BSOD's (BAD_POOL_CALLER and 0x0000007E) within 15 min of playing games, which have become worse by updating chipset drivers, etc.

Memtest86 run - PASSED
Chkdsk - OK
Defragmented - DONE
Windows repair - DONE
Clean install - DONE
Different hard drive - no effect
BIOS settings - Still crashes even on default speed and power
PSU - will be replaced soon
USB issues - trying this later today
BIOS update - next on list

I'm still trying to figure out why the system restarts, but I should have it extremely narrowed down after the BIOS changes in store for today and then a new PSU. Let me know if any of you have suggestions.

CPU - Core 2 Duo E4300 Allendale @ 3.04
HSK - Stock cooling
MBD - MSI P6N SLI-FI
MEM - G.SKILL 1GB (2 x 512MB) PC2 6400
HD -- 80GB IDE salvage
VID - XFX 7900GS 256MB
PSU - 350W salvage

EDIT: It is important to note that I've never had trouble booting/posting, just staying stable.

 

[Akuma2000]

If somebody has his Q6600 running stable on this motherboard at 3.0Ghz or more, please post your BIOS settings.

Thnak you very much!

 

[imported_Planatoid]

I finally found something that kind of works.

I'm using these settings in BIOS:
FBS: 1600
MEM: 800 (stock)
MP: 8
CPU Voltage: 0.750
MEM Voltage: 2.1
NB Voltage: 1.45
SB Voltage: stock
FSB VTT Voltage: 8%
Spread etc.: disabled

For 3.2GHz.

C1E disabled (although it may work with it on, haven't tested it fully yet), HPET off, and all of that kind of stuff. Like I've been saying in previous posts, my mobo will not boot if overclocked and the NB is above 1.325v. I played around with the FSB an booting, and once I get to a QFSB of 1200 or so, it won't boot normally.

Anyway, with the above mentioned settings, if I apply those settings and let it reboot, it won't post normally. But if I wait about 45 seconds and reset it, it usually posts, which is good enough for me. Usually as long as I don't power off completely, it will reboot as often as I need it to, I just have to let it restart, not post, wait, and then reset it again and it's all golden. I might care more, but I don't usually reboot a whole lot. And honestly, this thing's pissed me off so much by now, I could care less if it dies on me or something, but it should have no problem running these settings.

Just for info, I used to run these settings:

FBS: 1333
MEM: 800 (stock)
MP: 9
CPU Voltage: 0.375
MEM Voltage: 2.1
NB Voltage: 1.325
SB Voltage: stock
FSB VTT Voltage: 6%
Spread etc.: disabled

And I used to get BSODs randomly, and the CPU was not Prime stable. I'm almost certain it was because of the low NB voltage.

 

[Akuma2000]

Thnx Platanoid,

I'll try your settings when I get home after my work.

About the Post thing, I got exactly the same problem when I go for 3.2Ghz!!
(with the reboot and won't go further than post with the first boot).

Pretty weird.

I hope they'll fix this with a new BIOS update or something.

 

[Akuma2000]

WHAT THE HELL!!!

I'm beginning to get crazy with this board!!

3.2Ghz just don't work.
I think I've tried every possible setting!

It just won't boot! (black screen, no post, also not if I wait a few minutes and reset)

3.0Ghz (1333 x 9) works.
But like I said before, it will give BSOD's radomly.

But I never tried 3.0Ghz on NB:1.5v (my PC boots with 1.5).

So now I'm testing these BIOS settings out:

FBS: 1333
MEM: 800 (stock)
MP: 9
CPU Voltage: 1.375 (in CPU-Z on load: +/- 1.352 and idle: 1.376
MEM Voltage: stock (1.8 I think)
NB Voltage: 1.5
SB Voltage: stock (1.5)
FSB VTT Voltage: 6%
Spread etc.: disabled
C1,HPET etc.: disabled

 

[imported_Cynosure]

@ Akuma2000 & Planetoid:

These boards seem to have some FSB 'holes' in them, as for example I cannot boot with any FSB/Mem combo under 1330Mhz.

While each problem may be unique, I would suggest playing around with different combinations such as:
FSB 1333 & MEM 667 @ 9x Multi or
FSB 1350 & MEM 675 @ 8x Multi
From there, start bumping the speeds up with
CPU Volt: starting @ +.250 V
NB Volt: stock
SB Volt: stock
Mem Volt: 2.2 V
FSB VTT Voltage: 4%

Both of these points have been stable for me.
Update on my progress: i've acquired another hard drive, reinstalled new windows, and a new PSU is on the way. Results tonight.

Btw- are you using Manual or Linked speed settings?
Do you leave memory timing options on auto or have you given definitions?

 

[Akuma2000]

[fortress001]

Hello everyone! Reading the posts on this thread has been fun! I hope to achieve a good overlock. Here is what I am starting with:

Stock System:

Q6600 G0 2.4Ghz CPU
MSI P6N SLI Platinum BIOS V1.4
2GB (2x1GB) Patriot Extreme Low Latency 800Mhz 4-4-4-12 SDRAM
XFX Geforce 7950GT 512MB Extreme Edition Passive Cooling
Ultra-90 Heatsink w/Artic Silver
Raidmax KATANA Full Tower w/225m Side Fan
3x120mm Rosewill Fans w/Vantech Fan Controller

Windows Vista 64 Ultimate Edition

CPU 35 Degrees Celsius / 95 F
System 35 Degrees Celsius / 95 F

So this is what I have to work with before an overclock. It's very quiet with the
fan controller and the starting temperature is good. ... Before I lapped the Ultra
heatsink with an electric mini-sander, the temperature was at 56 instead of 36. It
was shipped out uneven, as seems to be standard.

So I'm just beginning to experiment with some overclocks on this board. I'm trying
to be conservative, I want to find a fast stable setting and put it a little lower
to be sure. While I experiment and run tests, can anyone recommend some decent BIOS
settings?

I'll post the results when I have something working well after testing with the
Ultimate Boot CDs tests (don't want to ruin an OS booting it unstable).

 

[Akuma2000]

See my previous post.

The settings I mentioned was the most stable one for me.
It boots fine and Windows Vista 32bit runs fine.

But I still get randomly BSOD's
(sometimes after 5 minutes, sometimes after 5 hours, and etc.)

I really tried almost every possible setting in my BIOS, but I just can't find a stable solution.

I'm running my Q6600 on stock speed again, because I'm tired of trial and error these past 2 weeks...

On stock my PC runs without errors.

I'm thinking about selling my mobo, and buy a Gigabyte P35, which is wel known for it's overclock performance.
Or to sell my Q6600 and buy a QX6850
Orrrr (I hope) MSI brings out a new BIOS version, which allows better overclock performance!
