Watch out. I tried that and the NB heat sink was not seated properly and I was over heating the NB when I tried to OC. I am taking mine off tomorrow and reapplying some MX-1. I was trying some OC 900/1800 and it heated up and froze after 20 min. Also I was trying to find the mem strap for this board which is around 423FSB and then mem performance drops off. When I tried 422FSB the computer locked up would not post. I had to wait till it cooled off before I could enter the bios to reset it. So there is a hole at 422 stay away. 425 works fine and I ran 3Dmark and other test with no problems

A few thoughts;
Make sure you're not trying to run your CPU to a speed that's unreasonable for whatever model you have.
make sure you're running CPU to Memory clocks unlinked.
Set the memory clock, and timings, by hand, to what it's rated for. You may have to run CPUZ to verify what to set and that it's taken. Set memory voltage by hand as well. Worry about OCing memory later.
Make sure you have good seating of the NB heatsink, put some cooling on it to help out.
Set NB voltage to 1.4
Put your RAM in the black slots
Note the amount the voltage drops from the setting in BIOS to measured; think about 1.4-1.425 setpoint
Finally, I found that I couldn't boot for some period of time above a certain speed (one I'd successfully run at before) after a CMOS reset but then kept adjusting some of the CPU Settings (odd things on the Speedstep page of the BIOS) and it booted again. Not sure if there's a correlation there or not.
Just a few things I've played with so far.

Thank you so much ! I got it stable to 1500 FSB and 800 Memory, I did everything you told me above. I set the my memory at 1.920 ( Corsair XMS DDR2-800 5-5-5-12 ) and the NB at 1.4. Now the problem is, I can't go over the 1500 barrier ( 2.62 Ghz ) What should I do next ? Thanks.

Now just raise your mem voltage 2.01 should be good 1600 - 1650FSB 2.08 1700 FSB
Watch the heat on the NB put a fan on it if you can.

Thanks for trying to help ! I really appreciate it. But its a no go with upping the voltage on the memory, won't even boot. I just can't get past this. ANYONE know what the problem is ? Thanks.

What are you setting in the bios for the FSB & Mem configuration Linked, Unlinked, FSB Ram and voltage vcore all the details would help.

Unlinked, as you can see some people arehaving the same problem as me. Goto the CPU Part of anandtech forums, and one of the threads has teh information in it. Somebody told me that raising the North Bridge to 1.5 Volts would fix the problem ? Is this dangerous ? How do I check the temperature of my North Bridge and what would be a good temperature to run it at. THANKS.

1.39 is fine what is your vcore settings I put my settings in my sig at the bottom of my posts Vcore 1.325 Ram voltage 2.08 NB 1.39 and that is for Unlinked 1650 FSB 825 mem and ram timing 5-5-5-12 2T

1.368 is the vcore of my cpu right now, but it doesnt matter if i put it to 1.45, the fsb won't go past 1500. There was another person who had the same prblem as me and said that rasing the NB to 1.5 V helped him. I was just wondering if this is safe, and what temperatures should I be running under, and how can I monitor the temperature of my NB. Thanks.,

NB runs hot when OC if you don't have a fan on it wait and get one before you start raising the nb volts . What slots are you ram in The black slots are making OC easier Put your computer settings in like I have in your profile it helps alot

Thats not bad! What are your cpu and mb temps with that new HSF. Do you use speedfan? It will adjust your fan speed automatically. Your temps should drop in the next few days. and it's John

well john, i use asus probe 2 for temp monitoring, and i have q-fan enabled which should throttle my fans accordingly. i'm topping out around 42deg cpu at default clock settings. am i to assume the mb temp is the nb temp? so far it's been same as the cpu speed.

k, back to 2.8ghz 400mem/1600fsb 1:1 ratio atm. have my mem set to 4-4-4-12-2t, gonna defrag overnight and run a 3dmark06 tomorrow morning.
vore and vdimm are currently on auto and i've set nb to 1.39 and mem volt to 2.178.

also, i see what u meant by it being necessary to modify the cooler, i used a wire cutter and cut out some of the plastic and bend the bottom fin a bit, both now sit properly.
cpu at 39deg and mobo at 37deg.

stupid cpu-z is giving me 2799mhz/399.9mhz/1599.7mhz for my speeds, rather upsetting with all the 9's instead of 0's.

it is amazing how easy it is to install arctic cooling fans, just amazing, when most other vendors give u about the same performance, at twice the price, and require u to remove motherboard for installation.

this is one is quieter and doesnt have a damn blue led on the fan, much more to my liking. i think from now on all my cpu coolers will be arctic cooling.

back to 2.1ghz 400mem/1200fsb (3:4) for the time being, 1600fsb was not stable, looks like the nb is runnin too hot.

might also need to check if it's seating okay, last resort would be to take it off and reapply thermal compound (dont wanna remove mobo). how much diff do u think stock paste and arctic silver would make?

Download speedfan and install it then go back and download speedfan beta 4.32 I'll help you with the rest. Q-fan and Asus probe are a joke. and don't use asus update for windows. Give all those push pins around the HSF another push to make sure your seated now that you finally trimmed that fan cover. Don't use a metal thermal compound for the chipset. Don't you sell MX-1 at your place. I am waiting for those temp sensors to come. They shipped from Cal yesterday so I probably wont have them till Mon, then I can compare the difference
I sent you a PM

don't have the mx-1 at this time, but i did inform our ppl to get the stuff in stock.

how would i remove the chipset hs w/o removing the mobo if i were to install either another asus chipset fan (maybe yank it from my brother's a8n-sli) on the NB. come to think of it i may have some other mobos laying around that might have chipset fans i can gank.

also what do u mean download speedfan and then download speedfan beta?

The only way I would remove it without taking the MB out is if we could get extra push pins(your job) other wise leave it a lone and smack a fan on it Ty wraps, screws, tape. Be creative. Sorry I didn't sleep last night to good thinking about this issue so I'm foggy today. You have to install speedfan 4.31 the setup program before you can swap out the beta exe with the orginal exe.

heh, sorry i'm causing to lose sleep. the HS seems it is sitting properly, i dont know if it'd feel as hot as it does if it didnt have proper contact with the chipset. will try to look for a fan to help the cooling. my case does come with a shroud that can install what looksl like a 80mm fan taht will help blow out hot air through the back of the case, the shroud is a bit low to be sucking air from the chipset, it's more for the video cards it looks like.

No worries, I took a cat nap now one eye at least stays open. Yea your MB temps seem high gets some good airflow going I have three 120mm fans going when I OC two when I'm not. My temps are cpu 30c core 1 and core 2 27c MB 30c HD 30c

u have those temperatures with cpu at 3.2ghz? what case do you have? my case has a 120mm fan on top and one on back both blowing air out (and another blowing cool air in at the front), dont think ventilation is an issue

coming from a x2 3800+ oc'ed from 2.0 to 2.6, i thought 38deg on my e6300 was pretty damn good. i'll take the plunge and remove the heatsink and reapply a new compound tonight, hopefully it'll boot up when i'm done. got my hands on a shin-etsu silicone compound which is said to be non-conductive.

so when u touch the heatsink on ur p5n-e sli, are u able to hold ur finger there indefinitely or does it get hot enough that u can't.

No when I OC to 3300 cpu 36c mb 30c core 1 and core 2 29c HD 29c @ iidle don't think they allow screen shot or I'd put one up. Your in Texas right? what are your air temps I live in CT air temp have been mild so far I leave window cracked and the air finds its way to my computer

The thermal compound usually take 200 hrs to perform best so leave that heat sink alone and let the board break in slowly. I don't keep my machine OC 24/7 more of a hobby for me and I mostly go for high clocks not stability. Yes i can kept my finger on there as long as I want. Did you ask about those temps that we talk about and how about those pins.

the response i got was he'll look into it. i guess i should let the board stay at 2.1 ghz for now and maybe start upping the fsb next week. even if he could find some push pins to send me it'd take a while to get here as they'd come from california.

temps here in tx these days are 50s during the day and low 40s at night. it's usually around 70ish inside the house since the heater would be on. my mom gets cold easily so 50s temperature means the heater goes on.

eventually i'd like to have the system set at 3.0ghz, about 1714fsb, tho i'd be happy to have 800mem at 1:1 ratio for a full 1ghz oc at 2.8ghz. will see after a few more days of running the system i suppose.

should i let the stock heatsink/paste settle in a bit or put in the new compound now and then let that new stuff settle. if the stock paste can suffice i wont have to remove mobo.

I put my system together Dec 22 so thats almost two weeks 120 hrs and the NB seems cooler than when I started I still have 80 hrs still, before it should cure maybe 1- 4 degrees more.
When I get those sensor I'll have better knowledge of what temperatures I actually have. Did they tell you what normal and max temps are(we need to find that out first). MB temps from Asus probe are not NB temps.
Funny thing this last E6400 I bought run so cool. I thought it was a mistake when I seen the temps on the first day I installed it. I reached in and first felt for warm air blowing out, cold. I stuck my hands on the fins of the cooler, not even warm I reached down to the base of the cooler, temps where about body temperature.
Core temps run about 5 - 7 below CPU temps. The other two, one on my P5B deluxe runs cool too 32 -34 Core temps are above CPU temps 36 37 The one I built for my son an E6300 is at 30 32 with core temps @ 30 32, but when I had the stock cooler on with AS 5 temps were about 38 39 with core temps in the forties.
The First chip is a freak or I did an excellent job of putting it on I still contribute the lower temps to Freezer7 Pro and the MX-1.
I did put AS 5 on the first Freezer pro and temps were higher. Its when I did the second one that I ran out of AS 5 and figure I give the MX-1 a try, seeing I had read good reviews about it and boy what a difference about 4 - 5 degrees so I took off the first one and reapplied the MX-1 and sure enough the same results.
Whats cool is the first day your temps are nice, but they get cooler ever day till it cures about 3 weeks and you don't have to reapply it.
They claim it last for 8 yrs. We'll see about that. So let it cure take your time maybe we can get by without doing any thing.
I just started leaving mine OC'd for 4-5 hrs a day, and like 412 FSB and 425 FSB plenty for me when I need it (makes me type faster).
Boy that was long.
I was hoping we could use ntunes and ClockGen as of yet no go.
Did you install speedfan?

Tell them you have three boards and you would like some spares, because your thinking of reapplying some good thermal paste on them, because the NB kepts melting your fan wires
