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

I `m getting a new PC shortly with this P5N-E SLI mobo together with a
C2D E7200 (stock speed of 266 x 9.5 = 2527) and some DDR2 800 RAM (2 x 1GB) of unknown brand. I `ll be running with the stock Intel CPU cooler. Do you think running the RAM at stock 800Mhz, with the CPU unlinked at 337 x 9.5 (3200) will be achieveable? What sort of voltages might I need on the NB, the CPU and the RAM? Thanks for any advice - and, yes, I am a noob!!

Get a better coller will help to increase the life of the cpu if u managed to run at that overlock the cpu life would be seriously compramized
 
Im sure that cpu is as tough as any of them. Isnt it voltage that kills not heat

You can put the nb on max voltage and cooling to test. Ive no idea on the other two, but edge it up I guess

Would not be surprised at all if you achieve that overclock on stock CPU voltage, but increasing the CPU speed will increase temperatures a little, so you may struggle with the stock cooler, but then again you may be fine (its not a large overclock). Put your memory at its rated voltage and keep it there - if for example your memory is rated to work at 2.1v then put it at that and it should be fine. If its not then you need to RMA it.

As for NB voltage I find putting it on the max setting (1.7ish) the PC wont boot. I generally stick to the second last and third last settings (1.56ish and 1.39ish respectively, dont know why this motherboard uses weird values like these). I have a Thermalright HR-05 heatsink with a 80mm fan attached to it on the northbridge and a zalman fanless one on the southbridge, and it still gets hot. Ive found that with this motherboard even if the PC is orthos stable for many hours, it still may crash when accessing a few hard drives or multi-tasking, and from what I can tell its due to the northbridge not getting enough juice or it is overheating.
 
Good to see that the yorkies do work on the P5N-E Sli i've only seen the q9450 running on them though, i assume the q9550 and q9650 would run no problem also?

Both. Too many volts and the silicon junctions give up, too much heat and it melts! I think it's usually heat that kills CPUs as the actual voltage limit is higher than stated, but a higher V would mean you'd have to run it really slow due to the switching heat. Or some really really good cooling :)
 
Well Ive had it above 80 on a regular basis and its ok. If you take it too high coretemp stops working, it only does upto 85c. Its still working ok and if a gpu goes this high I cant see it being any different if it has a good ihs
 
Hi All,

I am a newbie on this forum. I really need help from you all.

I build my own pc with the specification below:

Asus P5N-E SLI bios 0901
Intel E6850 3GHz
2 GB Corsair DDR2 XMS2 DHX PC2-6400C4DHX TwinX
Corsair Dominator Air Cooler
250Gb SATAII SAMSUNG
Artic Cooler CPU
IDE Samsung DVDRW
2 x 256Mb Quadro FX 3400 (SLI)
550 Watts PSU not SLI PSU
Windows XP pro SP3.0

I built this pc only for CAD purpose not gaming.

The problem starts when I selected the SLI rendering mode (Nvidia Control Panel), the Computer restart after asking a question to restart or not. The PC went into window XP startup and open a screen looks like a snake skin (I do not know what it is called) and then restart it again.

On the second restart, the windows provided me with 6 options (safe mode, ...., last know configuration and Start windows normally). I chose the start windows normally and the snake skin appears again and PC restart again. I had to choose the last known configuration. The SLI is still disabled.

I tested the graphics card one by one and it appears they are OK.

Or I might not know how to setup the SLI on the bios.

I really appreciate your advice and help

You need the max NB volts if you intend a high FSB but make sure you actively cool it with a fan or water. Mine has been at the max NB voltage for well over a year without an issue.
 
Maybe it depends what bios version you have but I ended up using the northbridge on max volts with no extra cooling


It can be a bit weird on booting sometimes but if you try it from cold and its fine but fails later I guess thats nb cooling

Thanks for the reply. Have got the E7200 running at 3500Mhz (368 x 9.5) with FSB of 1472. RAM (4 x 1GB DDR2 667) is running at stock. System is ORTHOS and Prime stable. Max CPU temp of 62/63 degrees with vcore of 1.34volts reducing to 1.296volts under load. Vista gives a rating of 5.9 to everything except 5.7 for the E7200. I am very happy overall!
 
Anyone know what ill have to do to get 8gb OCZ gold running at 5-5-5-18 to work on this board?
Ive got BIOS 0901
A Q6600 @ stock
Any advice welcomed. :)

I could not get mine to work (the 667 stuff) - but contact Tony on the OCZ forum. He may be able to help, and is helping me at the moment with this RAM, albeit for a different motherboard now.
 
Cheers for the update Hangtime mate.

Board crapped out on me in the last few months, can't run dual channel as the board now doesn't like two sticks in any setting. May buy a 2GB stick till I get back to the UK over Xmas so I can RMA the board for the second time. :D

The board has it's issues, but I think until new tech arrives, i'm staying with it.
 
3.8Ghz is very optimistic, it has been noted that yorkfield quads do seem to clock better than the old kentfields on this board though. you should be able to get a stable 3.2G with the right settings I would have thought.
 
Hey all currently at 3.23Ghz though not tested properly yet, only 20min in Prime small FFTs

My core VID seems to be 1.25v is that rite for an E0 Q9550? found it in CoreTemp, though if i turn speedstep and C4 State i think it is, in the BIOS, CoreTemp displays 1.10v when the multi's dropped to 6 from 8.5 (due to speedstep)

So is 1.25v my true VID? just little higher than i thought it would be.

Im running 1201 BIOS
