I am not sure. I think so. They are in slots 1 & 3. And I am only running them at 800mhz, 4-4-4-12, 2.1v.
I have tried upping my FSB to 1575 cuz someone early on in this thread mentioned that their board didn't like certain frequencies.
I have yet to mess with any voltages (other than putting memory to the rated voltage.) Could that be my problem?

At the moment, I am running @ 2.62 375fsb. Completely stable. Ran orthos for over 6 hours with no problems. And my temps never went over 53C.
I just don't know what to do from here.

Thanks

Yes - you've reached the point where you'll have to start bumping the core voltage to get higher. As soon as you do, your temperatures will start rising at an excellerated rate (faster than the rises you've seen by just bumping the FSB so far).

You can try a bump or two, but I don't personally advise it unless/until you replace the stock cooler.

 

[WickedSS]

Thanks spanki.
I think I saw a thread about great coolers for this board. I will look into that.

Thanks

Yea I hit that barrier on the standard voltage for the Nortbridge ,try increasing the NBv 1 step.
I doubt your CPU will need a voltage boost yet ,but try that if the NBv boost makes no difference.

 

[WickedSS]

Thanks Assimilator1. I will try that and let ya know.

 

[Elias824]

my board as well will not do fsb 1500-1600. anything above 1600 is seems to handle well with 1.45v on the northbridge. there is still some fsb holes on this board. I was hoping msi would fix them by now but they seem to be taking their sweet time.

 

[Assimilator1]

I found no FSB holes on my mbrd ,just an upper limit of 1650 MHz (412.5 MHz) which it can do @1.4v (though I've not done a long test to confirm real stability).

I tried 1675MHz but even at 1.45v I still couldn't get into windows (strangley at 1.4v I could get into windows but it would just lock up) ,I suppose it might work at 1.5v but I didn't want to try such a high (+20%!) voltage boost.
I did try higher vcores btw so it's not that ,must admit I didn't try higher VTT FSB voltages though ,what does that do?

 

[WickedSS]

Hi guys,
1st: Thanks for all your help thus far! You guys have been very patient and helpful.
2nd: I hope your patience holds out cuz here come more ?'s
I finally got it to boot over the 1500 fsb with these settings:
FSB: 1525
MEM CLOCK: 800(Just what the ram is rated at. also set voltage and timings to the rated specs)
CPU VOLT: .025(6 MIN) .0125(9 MIN)
NB VOLT: 1.3(6 MIN) 1.275(9 MIN)

The voltages are the different settings I have tried and how long they lasted with orthos before locking up.

My temps never exceeded 53C. (Still on stock cooling but have the arctic cooling freezer 7 pro hsf on the way.)
My psu is a 480 watt antec neo.
Could that be the problem?
Or should I be upping voltage somewhere?
Where do I go from here to keep cranking it up?
Goal is 3ghz like I have seen several e6300s doing.

Thanks again.

Hey guys,

I am new to overclocking and I currently have my E6400 + MSI p6n up to 3.0 GHZ. Not bad for my first overclock. Everything was going great until this morning when I changed my RAM timings (GSKILL to 5-5-5-15, which is the correct timing) and now my computer won't get past the MSI start screen. When I quickly hit delete to get into the BIOS, it will just goto the POST screen which shows the CPU, RAM, etc.

Anyone have any ideas what the hell to do? I have cleared the CMOS, but I still just get stuck.... grrrr Any help, would be great!

Ok guys,

I finally had time to do this and i like to thank you Assimilator1 for helping mr out.


It was easy and painless. I am at 2.4 and my temp are at 28c/32c before and after online playing. I am using speedfan to look at the temps. North brigde is at 38c but i really dont see it to hot.


Once again thank you.

 

[Assimilator1]

No probs
Though to really test stabilty & temps you want to run Orthos for 24hrs.

I've been doing more tweaking & testing on my rig.
At 3.25 GHz @1.3125v ,1625FSB @1.35v,760MHz RAM(4-4-4-15) @1.9v it did a clean run of Orthos for 25hrs

However if I try to run the RAM in sync (813 MHz ,4-4-4-15) it locks up within a few mins ,tried RAM voltage from 1.9-2.1v ,no difference.
Its OCZ PC 6400 rev2 so its rated at 800MHz ,4-4-4-15,1.9-2.3v.
I also tried +2% VTT ,locked up even quicker & then the bios forgot its settings!
With FSB down to 1500 its so far passed Orthos for 28mins ,RAM's @813MHz ,1.9v, 4-4-4-15

Anyone had any luck overclocking RAM on this mbrd?

You need to change 1 voltage at a time so you know which one is having an impact.

[edit] wth is going on with the forums formatting??:roll: ,the above was fine when I left it yesterday!

 

[WickedSS]

Thanks Assimilator1.
I took your advice and left the cpu volt at 0 and upped the nb voltage a step at a time and was able to boot and run at 1525 then 1550 just fine. When I went to 1575 and ran orthos, I got this message:

FATAL ERROR: Rounding was 0.5, expected less than 0.4
Hardware failure detected, consult stress.txt file.

Did I do someting wrong?
How do I know when to up the cpu voltage?

Thanks

 

[Assimilator1]

When upping the NBv makes no difference to obtaining stability.

That 'Fatal error' messege is when you've overclocked the CPU/mbrd too fast for its current voltage ,you usually get that rather than a hard lock up unless you're doing bigger jumps

 

[WickedSS]

so just start upping voltage on cpu a step at a time with current fsb until it is stable, right?

 

[Assimilator1]

Yes & with the NBv still at the higher than default setting you had it for before you upped it further & it made no difference.....if that makes any sense! lol

 

[WickedSS]

lol sad thing is, it does

 

[Assimilator1]

That's alright then

I'm off to see if I can get my RAM to run at the same speed as my FSB (406 real MHz)

 

[Assimilator1]

Damn ,no I can't!:frown: ,even with NBv @1.4v ,wth is going on?
Must admit I didn't try highr RAM voltage along with 1.4 NBv.

Anyone else had trouble overclocking their RAM at high FSBs?

 

[WickedSS]

Damn, I am stuck at 1575 fsb. I can't seem to post at 1600. My failed settings are like this:
fsb: 1600
memory: 800
cpu voltage: .0250, .0375, .05
mem voltage: 2.10
nb voltage: 1.4, 1.45, 1.5
sb voltage: untouched
fsb vtt voltage: untouched

I have tried 2 diff steps up on the cpu volt and then 2 diff steps up on the nb volt and have had no luck. Should I keep going up? If so, on which one?

I don't believe that temps are the problem since I ran orthos all nite at 1575 fsb and the first listed voltages.

Thanks from a newbie

 

[WickedSS]

Oh yeah, I have also noticed through my whole oc experience that I have had my memory settings set to recommended specs and never changed them. However, with each overclock, the post shows a change in my memory clock. Is that supposed to happen? I have System Clock Mode set to Manual and have disabled everything as suggested (d.o.t., eist, spread spectrum, everything in cpu & chipset features)

Thanks

 

[WickedSS]

HA! I have hit 1600 FSB! Finally!
2.8ghz with temps only hitting 53C during the hottest part of the day.:beer:

 

[Assimilator1]

Cool ,what did you change? VTT?
Inccidently ,I can't remember ,have you got a fan on the NB?

Btw its normal for RAM speeds to change slightly ,when you set say '800' MHz for the RAM the mbrd finds the nearest divider to get that speed without o/cing the RAM.

My supposedly stable 3.25GHz o/c crashed in GWs today ,back to the drawing board ,now set to 3.2GHz (1600FSB).........seems like we are heading to the same FSB! lol

 

[WickedSS]

I changed the cpu voltage one step higher than I had tried before. I still don't know when I should change my VTT or SB.

Yes I do have a fan on the NB. It is the one that came with the board.

That sux that your 3.25 crashed. Looks like you are at the same fsb as me now after the crash hehehehe.

I am on my way to 3GHz with the e6300 (fingers crossed). I just put the Arctic Cooling Freezer Pro 7 on and 4 new case fans and noticed almost 10C drop in idle temps and about 8C in load temps.

I'm new to forums - though I read help and read many of these MSI P6N Platinum OC posts I didn't find anyone having the problems I am or using my CPU, an 805d. And, didn't see how to just enter a new 'post' under this topic.

Anyway, I changed from an ASUS P5WD2-E Premium because I wanted to go SLI and got this MSI board. On the ASUS board I OC'd from 2.6 to 3.5 without a hitch. But, can't get any OC to work on this MSI.

Any ideas?

Welcome to AT

How do you mean you can't get overclocking to work? ,if you mean you can't see any FSB options ,you need to change FSB to manual.

WickedSS
Nice drop in temps
I haven't altered my SBv ,think I tried once & it made no difference but YMMV ,I tried altering VTT but same with that.
Btw I'm somewhat dissapointed with this mbrd ,I was hoping it would at least be capable of 430 MHz(1720) as various reviews were at least hitting that & some more ,oh well.

What kind of ram, speed etc are you using?
What are your settings in the bios for ram and processor?
