Got it, thanks franz.

you need to have active cooling on your NB and your answer is yes,this NB temp can limit your overclocking abilities.

pciex16_1 is for overclocking your PCI Express bus speed and I don't know how is can increase your overclock stabilities .

As I post many time before EVEREST Ultimate Edition 4.20.1261 Beta and newer beta version show true value about this board and also show MCP temp which is south bridge temp.please post screenshot from those version on Everest.

This mainboard is not so good for overclocking quad core cpu because it has voltage problem with quad core cpu .
About e8400 cpu which is 45 nm cpu just the new 1403 bios can support it but I suggest that you use e8400 with newer boards or wait for newer bios because it's first bios that support 45nm cpus and I still need to be test.

The best way to read NB temp is to use external sensor or termo meter .at the moment everest show mainboard temp which user said it's NB temp but it's not.It's the temp of the chip on the mainboard .

Hi guys

Although this is my first post here, I have been following this thread for a VERY long time and I'd like to thank you all for helping get the most out of my P5N32-E SLI.

I'll be honest, I hate this board with a passion because it's been a right PITA from day one. First of all the onboard sound stopped working, and then both network ports died too. Turns out the thermal pad on the southbridge hadn't been installed properly and was only covering about three quarters of the chip. This really isn’t acceptable on a £125 motherboard from a supposedly premium manufacturer.

Anyway, after discovering that and applying ceramique to both bridges and some 40mm fans, it managed to hit 490MHz FSB. 490MHz FSB with the stock heatpipe setup isn't too bad!! I've attached a couple of pictures just to show the setup I had.

Just to reiterate what others have said: 1203 BIOS with additional cooling is the way to go. Or get a better board

I was unable to achieve 3.2 (400x8) until I upped the pciex16_1 to 110 and lowered the LDT to 3x. I remembered that on some older motherboards you unlocked the bus by raising the speed from default so I gave it a shot. As strange as that sounds, that helped me out and now I am completely stable at 3.2 with the following voltages:

Vcore 1.35
NB 1.40
SB 1.50
Vht 1.25
Vtt 1.25

As far as the MCP, why does Nvidia consider that the SB? Luckily my case has some temperature sensors in it so I can measure the NB, but why would anyone want a SB monitor instead of a NB? I'm going to have to take the heatsinks off and put some AS5 on both of them I guess. Does anyone recommend doing this? I have active cooling on both of them and my SB still reads in the 60s.

Edit: congrats dervman. I think we all agree with you about this board. Could you post your actual speed and voltages for us as reference? Thanks man and good job.

I'm sorry I was wrong, the system did not become more stable or stable at all.




Ok new screenshot for you.

LDT Frequency is for connection between NB and SB and I don't know why you need to change it to be able to have stable overclock.

"As far as the MCP, why does Nvidia consider that the SB?"
what do you mean ?
MCP = Multimedia Communications Platform = South Bridge
SPP = System Platform Processor = North Bridge

we want to know temperature of both NB and SB because they both are part of our mainboard and they both temps are important for our overclock stabilities.

My bad, I confused the two, like I always do. Anyway, Im in the process of finding my NB temp right now. I cant wait to see what it reads.

AS5 really did nothing for my NB temp and actually made my SB temp increase. I put another fan blowing on the NB and now my temp is around 50C idle. I think I might invest in an Antec SpotCool and put that directly over the NB. This is very frustrating. As soon as I put the side of my case back on the NB temp shoots up and my computer freezes. I guess that was the cause of all my problems.

i should really be staying more on top of this thread, but am i ok with BIOS 1205 as well, or should i really be running 1203?

bios flashing is about the ONLY thing this board can seem to do well

first of all let me tell you bios 1203 is the best bios for those who want to overclock their system otherwise you can always use the most releast bios for your board.

I have this board,I overclock my cpu very well and I don't have problem with it BUT I treat my mainboard and my computer like it's my baby or my girlfriend.

I check temps and other things and whenever I think it need any thing ,I support it.when you want to have good computer with good overclocking abilities you don't just need good mainboard.You also need good power source with clear voltage.you need good ram which was approved for your mainboard and other user who have your mainboard confirmed that they don't have problem with that ram.you need good cpu with approved and confirmed overclocking abilities.you need good cpu cooler which is designed for user who want to overclock their system.like many user said before for this board you need active cooling for your NB and SB (not just a fan on top of stock headsink ,you need pro SB and NB which was specially designed for NB and SN ).you also need some headsink for MOSFETS.you need good case with good air flow and cooling system.you need ....

THEN YOU CAN SAY OK i HAVE GOOD SYSTEM FOR OVERCLOCKING AND START.
