i set fsb to 1600 and memory at 800 unlinked for a 1:1 ratio, but after boot up (still doesnt not always boot straight up), and bus speed is at 350 with rated speed at 1400 and memory running at 400mhz with a 7:8 ratio.

not sure why the bios can't simply set the stuff to where we told it to set it to.

i will prob have to just left everything on default and wait for a new bios.

funny thing is, when i go to asus website, they have the phoenix bios from september listed on the site for p5n-e sli, wonder if i should try that one.

I had kind of the same problem. Dropped my multi to 7, raised fsb to 500, increased NB voltage to 1.5 (with cooling fan right on it) increased vcore to 1.5(reads as 1.4 under load)
Memory tweaking is rough. Waiting til the new bios to OC that

Weird thing about it was how it seemed to do all kinds of funky stuff at the lower fsb's with the higher multi. Thing is rock solid now. Eagerly waiting to OC my mem with a new bios version though.

If you go to that link in my previous post. He has a Xeon too and I think he Maxed out at 503

I'm not sure what my max is. I am pretty happy with 3.5 It's stable now so maybe it is time to see what my max fsb is. I was just surprised by how easily it got there.

Now that I know what voltage it takes to get there I think I will also try raising my multi back and seeing where the CPU tops out. It's certainly an easy board to work with. Anytime it wouldn't save my settings I knew it was something it just didn't like.

Do you have fans on both chipsets. They get awful hot. I put a heatsink on the SB cooled it right down. I can run smoothly at 3400 8x425 and I am also very happy with that.

 

[adder1971]

I didn't put one on the southbridge. (tried putting an old southbridge sink from another MB but it didn't fit) I have an 80mm on the northbridge.

I have this massive fan mounted to the side of my case. (120mm) but its hooked through directly to 120vac through a fuse so my case never gets above ambient temps. lol

I have to figure out what kind of CFM's that baby puts out.

(it used to go in a case the size of a large refrigerator to cool of gas analyzer equipment)

One thing that surprised me too was how much higher my memory bandwidth is now.

Stock was 5,700mb's and now it is 7,700 ish.

Memory bandwidth drops off after 424 at 400 mine was 7537. At 422 I crash ever time (strap hole) 424 is solid. Try 424 and see what you come up with for bandwidth. Also 5-4-4-15 2T gives me better Super PI score than 4-4-4-12 2T ??????

sorry if this has been answered before, what kind of heatsink should i put on the sb, and how do i mount it?

This iis the one I put on ZALMAN ZM-NB47J Aluminum Heatsinks

This one also will work ZALMAN ZM ? 32K Heatsinks only
Instruction are simple to follow no need to take MB out. Lining it up is tedious. Make sure you are not resting on any small components or damage any on them
Remember these will not work if you are in SLI mode or have plans in the future of adding it. Go a few pages back for the heatsink for SLI mode

I'll give that a shot. I did notice that my timings did not seem to give me any noticeable difference in bandwidth or super-pi times. Not sure yet if the change comes from FSB increase directly or as a result of the increased core frequency.

And I can definitely confirm this board does not like 1T regardless of memory voltage.

Yes, I used MX-1 instead of the paste they give you and they have push pins so it locks it down. If you go back and look through the previous post in the thread I think I gave a full install method before. Zalmans web site also explains how to install it.

 

[Xdreamer]

sorry...

 

[jkcheng122]

changing the nb chipset heatsink will likely require a mb removal tho, primary reason i havent done it yet, another reason being last time i did it the mobo i couldnt get my rig to post anymore and had the board replaced.

 

[jkcheng122]

one other thing i should note for people who are thinking about doing SLI mode on this board. if you use 2-slot video cards for SLI, you will have absolutely no space for a pci card.

i'm using 7900GT with zalman vf900cu on them, and the bottom card is very close to almost sitting on top of my x-fi card. future pci add-on considerations such as Killer NIC (i play wow, and this thing has been proven to make significant improvements in mmorpg so i am considering getting it) or if you're interested in a physics card are pretty much out of the question. i will likely try to sell the 2x 7900gt's and upgrade to a 8800gts, still waiting to see how they perform in dx10 apps.

 

[Xdreamer]

sounds very impressive

 

[Core2]

Yes, The only heatsink that is needed is the SB. NB heatsink is fine. Just get a chipset fan or other means of air flow on it. This a must if you are thinking of overclocking this board.

Also I just saw a suggestion in another thread to try lowering the NB voltage once you get a stable CPU speed, and re-check for stability. Since mine is higher than yours, hopefully I will be able to put it back to the default setting of 1.39.

Your right, and I haven't had to go over 1.39 yet.

BTW what is your Vcore in CPU-Z under full load for both cores? I have about a .10 vdroop on mine.

Mine is not that bad about .03 - .05 The highest I had to set my vcore was 1.35 and I don't think I needed that. At stock speed I have my vcore set at 1.25 and can run 3Dmark 06, and get the same scores as if I set it at 1.325. BTW I use speedfan to monitor voltages.

 

[JonDoms]

Hey folks,
I'm cross posting my findings to here from the Asus boards (JonDoms).

So this is what I have gotten to work so far, but it is still not Prime Stable (actually Orthos).
SuperPi I can run 2 SuperPi with Affinity set to each core for the appropriate ap and I get 16 seconds for 1M. When running only 1 instance I get 14 seconds.

My setup:
Core 2 Duo 6600 @ 9x 400fsb (1600Mhz) = 3.6Ghz. 1.39volts read from the bios.
Using CPUZ I get a fluctuating reading from 1.178 default boot up to 1.36 -1.38.
Using SpeedFan Beta version 4.38 I believe, I see Core 1 @ 1.42 and Core 2 @ 3.65!!!! I think this is a bug. What are your experiences?

2GB Crucial Ballistix Tracers Rated for 4-4-4-12-2T @ 2.2v
I can't tell what the mobo is actually setting the vDimm at as I do not know of any programs to monitor this nor do I know if the mobo supports monitoring this. Anyone help here?
Anyways running this at 800mhz so it's 1:1 with the FSB. Unlinked mode.
Timings wise I am not Orthos 4 hour stable @ 800mhz with 5-4-4-12-2T @ ~2.2v. I can run it for 4 min and then I get an error. I will try 5-5-5-12-2T then 14-2T and see if I can get her stable for 4 hours.
Why 4 hours? Well over on HardForums they have a thread for Intel C2D CPU OC database. One of the criteria for this is 4 hour stable. I set my bar at that also.
Link here: http://www.hardforum.com/showthread.php?t=1138241

Northbridge was unstable at 1.3v for 1600mhz. I upped it to 1.5 and it has been stable since. No lock ups or reboots. With the 1.3v it locked up and or rebooted when I ran Orthos.

Other stuff in the system:
EVGA 7950GX2. 8800GTX in the mail for tomorrow. Hope I do not need a clean reformat ugh.
X-Fi Platinum
Zalman 9700
Silverstone TJ07 with some fans throttled back.
Silverstone CFP51 -> http://www.silverstonetek.com/products-cfp51.htm
All in all my temps are pretty cool this morning.
Core 0 reports under load 42C and Core 1 reports 54C. Via Speedfan.
Temp2 (Motherboard I think) is around 38C under load.
Idle the system vaires depending on the time of day. In the morning it could run at 34C and 37C for the CPU and 32 for the Temp2.
At night it runs hotter since it's been on all day 38C & 42C for the CPU and 38C for Temp2.
Bios 0202. Still waiting for the next version.
Am I leaving anything out to help this thread out?

you should be okay on not needing reformat with the 8800gtx (wish i can afford one)unless u're running vista, which nvidia still has no driver for.

i too could not get 1600/800 to run stable until upping the nb voltage to 1.5. now that it is stable, i will try tightening the memory timings to see if i can squeeze more performance out of the memory. might also try to push 3.0ghz my e6300.

First, What kind of cooling do you have for the NB and SB. Your problems could be that the NB and SB are just over heating. The E6600 runs a little hotter than E6300 or E6400 so you can expect a warmer CPU temp. If you browse through the posts in this thread you'll find my settings to setup speedfan for this board and some steps to cool down the NB and SB and lot more of info. I know it's a lot of reading but, it saves us some retyping. Do you have your ram in the black slots only? vcore seems a little high. Your probably going to need more NB voltage than us with that E6600 1.5v should do it.
Try dropping your multiplier down to 8 or 7 see what happens.
