The FSB you set in the BIOS is labeled as "QDR" meaning Quad Data Rate, i.e. 4x the actual frequency (since the Intel architecture makes 4 transfers per clock cycle).

2) Zalman 9500 clears the NB heatsink just fine, even with a 40mm fan sitting on top of NB heatsink.

As an aside, the Zalman 9700 also clears (I have one on mine), and that thing is just a beast. And, unlike most of the 680i boards, it does not require any sort of modification of the backplate.

It looks like it would IF you changed out the stock NB. I'd be real weary about the circumference of the shroud and whether it would cause a problem.

here's a quickie:

When I get my replacement P5N-e next week, I'm going to flash it to 0401 (since I have 4x1GB). I've read that you need to clear the CMOS after flashing it.

Do you really need to remove the battery to clear the CMOS these days, or is changing the jumper enough? I haven't taken out a CMOS battery in like ten years and the little buggers can be obnoxious.

Thanks for the response, thats actually the fan I was looking at. But whats the most efficient way to attach it to the Asus NB heatsink?

See here: http://i4.photobucket.com/albums/y119/slessard/DSCN0277.jpg

I mounted the fan on the CPU side of the HR-05 SLI and it blows toward the VGA card.

Thats a nice setup and an excellent OC, but the HR-05's cost much more than the mini kaze and the tiny cooler master combined.

Thanks for the pic! I see now that the HR-05 SLI or the original HR-05 will work wonders for my setup. Now I've just gotta find one online. :D

Welcome Aboard KalieMa

Thanks for the nice detailed report.
I have seen a big difference in the FSB holes. With the 0401 I haven't yet to find a FSB that I couldn't hit below 460. The 0202 419-422, 445 - 465 were all dead zones for me. A lot of people were having problems just hitting 8x400. That is what I'm waiting to hear about and memory issues that were on the 0202

As far as heatsinks this Cooler Master heatsink is by far the best bang for the buck that I can see. Put the heatsink on the SB Fan on the NB stock heatsink (no need to change it)

Stability testing without Windows. I agree. There should be programs that don't run in a windows environment. I just don't know what they are.

Thanks for the welcome. As you can see by my join date, I'm a little oldschool. Learning about "FSB holes" has proven more difficult than I had imagined, but not much else has changed since the old days. True jumperless overclocking is awesome and the ability to flash the BIOS from within the BIOS from a USB device is ... well ... OMGWTFBBQAWESOME. :D

On RAM/Timings:

I'm doing some more testing at the moment to learn about the RAM config. MemTest86+ is my first line of stability testing. If there's any problem with the timings being too tight for dual channel operation or anything it'll find it first. With my RAM running in the black slots at the defaults for 0401, it is decidely unstable. I think it's putting the RAM at 1T. When I go into the BIOS and switch ONLY the CMD rate to 2T, it's all good. EPP Mode (which sets it to 1T) is even less stable. I'm really curious about the timing issues since, well, I paid extra for RAM that'd run more effectively at tighter timings. Considering that the RAM is "SLI Certified", I'm guessing it's a mobo issue that nVidia/Asus are going to have to continue to work on.

On CPU Overclocking:

Knowing now about the holes that exist, I'm going to go back and do a full stability test with various settings. I have a strong hunch that I can get beyond 3.2 GHz once I figure out the RAM stability issues and the CPU stability issues. I know it's not a cooling issue, so it's got to be something with timings, NB cooling, or something else.

On cooling issues:

I too have a ThermoHawk 200. My Southbridge, unheatsink'd, is getting up to 190 degrees farenheit. Ouch. I just don't have any heatsinks small enough for it but I'm still digging around my old pile-o-heatsinks.

I checked the MOSFETs on the back of the board and they don't seem to be getting hotter than 90-95 degrees, which is more than cool enough for me. I'll have to check em when the system's under heaver load but that's not too worrisome.

The top of the NB cooler is approaching temps of 100-110 degrees with a 80mm fan blowing on it from about 5" away (resting between my video card and my Scythe Ninja). It's alot better than the 120+ I was reading earlier though.

On LiveCD-style stability testing:

I'm plainning on moving to a WinPE environment like BartPE once I find the most stable settings in MemTest86+. This may not test the SATA controller but it'll be a good "Level 2" diagnostic. I can run Prime and Orthos from BartPE as long as it's got the XP Pro kernel running, since it supports 2 CPU cores properly. Once that's OK, I'll move on to stability testing in my Vista Build 5840 install that's running on my Raptor and I'll be able to do more in-depth testing with 3DMark and/or other 3D apps. That "Level 3" testing should be the be-all, end-all test.

Things have changed alot since the old days but one thing remains the same: Overclocking is a blast! I had forgotten how much fun this stuff is. I haven't had this much fun since my first Celeron 300A Slot 1 with some funky sandwich cooling action. This stuff rocks and the Asus board makes it so much easier! :D

I remember having to clear the BIOS after every failed OC attempt. That took so much longer! Overclocking my old K6-2 with jumper settings was a royal pain too, espically after it was put into the old case I had. That old case would slice my hands up and draw blood every time. And I had to walk five miles uphill in the snow just to get a decent aftermarket heatsink...

You can use just about any heatsink that is no taller (higher) than about 3/4 of an inch. Beyond that, you will have problems if you want to run 2 VGA cards in SLI.

The one I have on my SB is from Vantec and iic copper and runs about $9.00 Model CCB-A1C. It comes with a couple of heatsinks for the SB and a active heatsink for the NB. The NB heatsink is too little for this application but the other sinks in the package are great.

sweet, it's nice to have some more old-skoolerz in here :) memory holes seem pretty much no-existent with the 0404 bios. i accidentally set my mem timings at 4-4-3-4 2t and it even worked like that.

Where can I procure this 0404 BIOS you speak of? The 0401 is nice, but I'm sure Asus has more up their sleve.

I wish there was a changelog for these BIOS updates to give us a clue about what's modified. I know Asus must have one internally, it's a shame they don't publish them.

the 300a was an awesome chip. these core2's are downright amazing and this coming from an all AMD background guy my xp2500+ was a decent enough OC but these are near insane.
leaving all the cpu config settings to enable except for speed step and i can get to 3.7 with ease. not stable on both cores mind ya, but dang its something else.

haha, nice catch. 0401 it is. my bad.

Well, I got everything backed up and backup again. I am finally ready to upgrade my system. Wish me luck. I'll be back tomorrow probably, hopefully with only good things to report.

i have only had to do that once. i always try clearing it solely with the jumper first. but i did have one major snaffu where i was required to remove the battery to get it back operational.

NB Heatsink Research:

After reading here ( http://www.hardforum.com/showthread.php?t=1142928 ) and here ( http://www.hardforum.com/showthread.php?t=1139486&page=5 ) about NB cooling, I'm pretty much set on getting an HR-05 for the NB. It's a beastly piece of gear that should tame the beast and allow me to pump up the Vnb quite a bit more.

SB Heatsink Research:

I still haven't found a decent SB heatsink. If the HR-05 SLI will mount on the tiny bracket-mount holes, I'd be down with it. If anyone has an HR-05 or the SLI version, could you please ost some details on the mounting clips? I haven't been able to find much info on that important detail...

RAM Stability Testing:

This is still ongoing. I'm trying it out at 1600 QDR FSB with RAM linked (800 DDR) at 2T, rest auto. Everything seems to be working well after 2 passes in MemTest86+. I'm going to try some 1T action next with the "Linked" mojo.

i've been having so much stability i haven't really messed with the 1t yet. hopefully it works well for ya. core2 tried it and i know he couldn't do it with the older bios.

Yeah. 1T is a no-go so far. MemTest86+ 1.70 doesn't just paint the screen red with errors, it eventually locks up completely. :)

I'm going to keep poking around and see what I can turn up. Been scouring all of my old forum sources, newsgroups, and websites for any info I can find and coming up blank.

Question:

Anyone know if Asus has an FTP server that they use to stash all of the new beta BIOS files? I remember that Abit and A-Open used to have open directories on their FTP servers full of beta files but it seems that the old, reliable Asus beta sources are all gone...

what mem freq and timings were you using besides for 1t?

"Auto". I'm not sure what it's setting it as, probably the SPD default on the DIMMs. I'm trying different settings there now to see if these will make a difference.

So far in my tests, I found that the MemTest errors out much later in the testing with the Vdimm bumped up from default to 2.178. I'm going to keep it there for the duration of my memory testing and, once I've found a stable setting, relax it a bit to see if it'll be necessary.

Just started a test at 5-5-5-15-1T, gonna see how it goes..

do you know if those are micron d9's? i'm pretty sure mine aren't although some older ones were supposed to be. i can still get to 1000mhz with them.

The mounting on the HR-05 and HR-05 SLI uses one of the included bracket (there are three, you need the smallest one). It is then attached to the MOBO using the two included spring push pins that allow mounting directly to the motherboard holes (where the ASUS push pins are located). The heatsink on the SB is the same mouting as the NB. ie, you can use the HR-o5 and HR-05 SLI on EITHER of the NB or SB. However, for the southbridge, just get a heatsink that attaches with some supplied tape and it will do fine. The one in my picture is from VANTEC and the entire kit sells for around $9.00

See here: http://www.vantecusa.com/p_ccb_a1c.html

It does not tell you but it comes with a passive copper heatsink that is about 1.5 inches square that fits perfectly. You can also use the active HS on the south bridge also.
