Default Overclocking issues ASUS P5N32-E SLI

I having no luck overclocking with this board.i have read through the guides,disabled spread spectrums,linkboost,gpu ex and i run my ram in unlinked mode. Whatever i do 300fsb plus ends in a BSOD and a reboot when running a game or 3dmark.As i understand no vcore voltage adjustments should be needed until you pass 3ghz but i cannot pass 2.7 without problems.

@1192 fsb ive run orthos and super pi 10 hours plus with acceptable temps(idle cpu 35 c system 28 with the aid of a 3200rpm chipset fan on the nb heatsink,load 47c and 34c) ,my ram passes memt32 allthough i havent run that for more than one hour .Im stuck atm and have no clue what to do or try next,i know my ram isnt highend ,could that be holding me back ? Or perhaps the psu ?

Just guessing here and ive tried raising the vcore voltage slightly with the same results,also 4 different bios-updates.Dont know what to look for,wich part i need to change for upping my chances to reach 3ghz.Hope some of you can assist somewhat,thanks in advance.

The 680i's have a real problem with the memory sync'ng with the FSB. Try a 1/1 FSB/memory divider. If you're running your FSB at 1500, for example, put your RAM at 750mhz.

FSB = 2xRAM. That's the only way I could get mine stable at this overclock, and I tried everything.

Thanks for your reply xion,appriciated

If i understand you correctly i need 800 mhz ram and set that to half my fsb for a linked 1/1 ratio? The ram i have now is 533mhz so no use trying more overclocking until i change it ?

I was gonna go for KHX6400D2LLK2/2GN 2GB 800MHz DDR2 Non-ECC
Low-Latency CL4 NVIDIA SLI-READY (Kit of 2) 4-4-4-12 2.0V
theyre on asus qvl list and i hope they will be a good choice
i've also heard of mixed success with enabling sli ram when overclocking ,any wiews on that ?
Again thanks for your help

Better memory probably wouldn't hurt you if you want a decent overclock on the 680i. You need to keep your RAM at 1/2 your FSB for it to be stable.

The Kingston looks fine to me. I'd say don't worry about ECC/SLI memory; I've yet to hear of any benefits from it. 800mhz ram should be fine. That would get you to 3.6gHz on a 9x multiplier.

My bad. It's a 650i. I remember hearing someone else complain about not being able to go over a 300FSB with those. I think they said a bios flash took care of it.

You guys are wrong, it sure is a 680i,it has the same pcb and sb/nb as the striker extreme and people are hitting 400+ left and right with it reading on ASUS forum.

It is the recenty released ASUS P5N32-E SLI PLUS that uses what ASUS call hybridup technology = 650nb/570sb

I dont blame you for getting confused by the model names though,hell most people that bought the PLUS model initially thought it was a 680i mobo,it shares the same pcb with the striker extreme and the non plus model .Mine and the first released batch of the P5N32-SLI even has the model name on a white sticker and peeling that off revals the striker extreme name.As you can see they look identical ,only dif is the nb/sb and that the PLUS model uses tantalum capacitors only.

They claim they released the P5N32-E SLI PLUS due to vdrop voltage issues and growing pains with the 680i chipset on the P5N32-SLI but now theyve released bios updates that cures that problem,go figure

Yeah, that's what confused me, that "PLUS" on the name, because I always thought it was a 680i. I scrambled over to newegg real quick when Hex posted after me and saw the P5N32-E SLI, didn't see the "plus" after it and it said 650i so I thought "okay, guess I was wrong."

Should've stuck by my original statement. And what the heck? "Plus" usually means better, doesn't it? But in this case it means an inferior chipset? Yah, that makes sense.

So I think a 1/1 ratio would do you good after all. I'd try it if you're having problems out of your OC.

Yea ASUS apparently used the 2 x 8 lanes in both chips and combined them into 2x16 or something.Theyre blowing smoke in people eyes a bit with calling it a 680i mobo,on their own forum owners of that board didnt even know what exactly they bought.A majority thought it was a 680i board and som got quite pissed about it eventhough tests show very few differencies in performance.

Heres a link if you wanna know more ,one statement from it though:

We've found a problem with SLI scaling in Half Life 2: Episode One before on other motherboards, but most of the time reinstalling the drivers or fiddling with some SLI specific BIOS settings fixed this. However, despite numerous efforts to rectify the problem we still could not enable SLI scaling.



Not so good since the striker board they compaired it to scaled sli performance in the same game just great.Might be a fluke but im glad my mobo is th non plus model even if it has a mix of tantalum and electrolytic capacitors.

Thanks again Xion,will be getting the kingston ram asap and give it a try

I have a ASUS P5N32-E and it was a horrible board looked night crap overclocking and could get stable even at defualt clocks. It hated my Corsair PC6400 Dominator memory had to undergrade my BIOS to 0302 to me able to use the PC. Got a ABIT IN9 MAX WiFi last week and it has worked perfectly i can even run my memory @ 2.1v /4/4/4/12/T1 with no problems while on the P5N32-E i system would crash all to hell with more then 1.9v for the memory. I have still yet to send it back.

In ASUS's defence for the P5N32-E PLUS they NEVER said it was a 680i not once they classed it a 16x PCI SLI board and every thought it was the 680i.
