All of the boards that use thermal management use the in-die thermistor for that function. The only difference between them is whether they use it for MBM/BIOS temp monitoring as well. Some do, and some don't. The ones that use the diode reader for MBM/BIOS monitoring as well as thermal management are going to read the wrong temp because of added resistance in the loop. If you hook up an outside reader onto the board as well, your temp measurements will be even further off. I would highly recommend NOT adding a diode reader to this board, because the results that will be read will not be accurate within 5C. You might as well use a stick-on thermistor.

Well I thought about that too. I know Asus wouldn't back off from using the in-die diode for OCP.
I've got to find a way to read that temp... Heck, I can't even see the socket probe, can you? Last edited by bigben2k; 12-19-2002 at 03:54 PM. |

I don't think the ASUS uses one. I think it reads both temps off of the diode (BAAAAAAD!). My EPoX uses a thermistor for software monitoring and the diode for thermal protection.

Here's an interesting RAM test on an Epox 8RDA+.
In short, the max ram clock achieved is 200 (2-2-2-5) synchronous, but can do 220 (2-2-2-5) asynchronous, with a single Kingston 512 3500 stick. (Note how the reviewer didn't state what the Kingston RAM is spec'ed at, doh! He also maxed the Vdimm, at 2.9) He could have simply linked the reader to the Kingston webpage on HyperX memory, but no... |

There are people running those timings at much faster FSB speeds, using PC3500. The new BIOS editions fixed alot of RAM issues (there were a ton). I'm currently running 2-2-2-4 [edit: wrong number!] on XMS2700 at 190 FSB. I have got it up to 205 FSB at 2-2-2-5, and up to 215 at 2.5-3-3-8 (lower mult, anything under 10X gives a 5-10% processor performance hit, which the memory bus can't make up for--error in the BIOS that still exists). The reviewer was wrong. Plus, he probably was using the stock NB cooler (sux) which greatly limits the FSB speeds on this board (I'm surprised the thing didn't melt). When you put a new chipset fan on, you get a massive gain in OC ability (for me I went from a max in the 180s to 215, and my timings at 180 were higher than the 215 timings).

Need I mention that all those speeds were SYNCH, with AGP locked at 75?

JTrouma: My 1900+ is a AGOGA-9 (I think on the 9, maybe a Y), and runs at 1900 Mhz watercooled 24/7. The chipset fan is a Vantec Copper Iceberg, which tends to cool about 6-7 degs lower than a blorb, 2-3 degs lower than a cryorb.
Before you clock, flash to at least the 8RDA2C10.bin bios and install the new fan (lap the shiz out of it). You'll then have good luck. UNDERCLOCK WHEN FLASHING THE BIOS! Also, don't use a GF4 unless you want to nuke it and bear in mind that some Crucial, Corsair DDR433, and Kingston memory still has a few issues with this board. If none of this applies to you, happy clocking!

I mounted my A7N8X last weekend. Dropped the NB heatsink and put my twinplex waterblock on it, fits nicely. I'm still using my old Maze2 for the CPU, since my TC-4 has not left the shop yet
 Using Corsair XMS3200, my TBird 1GHz AXIA went up all the way to 200MHz FSB (sync mode), with a 7.0 multi = 1400MHz stable under W2K and 3DMark. RAM timings are @ 2-2-2-4. Temps are MB->32°C CPU->36°C (whatever that last one means... i don't know where the temp probe is). All this in a system equipped with 1 PAPST 4412 N/2GL on a D-Tek HC, and a modded PSU (Seasonic 400W with a PAPST 8412 NGML). It means, very quiet. I'll try the 7.5 multi but i doubt my old tbird can handle 1.5GHz... The mobo doesnt run hot, i was even surprised by the memory which was very cool (compared to the mem on my GF2 GTS -> burnin' hot, even with heatsinks). The south bridge is rather cool to the touch, so i don't see the need for a HS there. Overall i'm very pleased with this MB. 200MHz FSB with uber aggressive timings... It's christmas  Airspirit: why not a GF4 ? (i'll get one when the FX is out, so i won't pay too much...) |

Excellent work gmat!
Did you figure out which settings give you the optimal memory bandwidth, or is this not an issue with a TBird? |

Not yet. I spent my sunday on installing w2k pro... Of course it was running at spec (mem @ 100) during the install.
It was about 23:30 when i attempted the overclocking, installing and running 3DMark and some cpu intensive programs led me to 01:00 when i felt a bit tired - and i had to go to work today. I'll install Sandra tonight and watch those mem scores. I suspect that 200 FSB sync is the best though (i cant see how any lower FSB freq - sync or not - would be better)I won't get lower than 2-2-2-4 it would be foolish... And i want a stable setup. |

Hehe i'm now at 200x7.5=1500 ! And still 2-2-2-4 & sync with FSB.
Reported CPU temp is now 39°C (under load). I tried a few other settings for the mem but Sandra showed the best scores for 200 FSB with sync (which the NForce2 is desgined for, anyway). I like those nice, round figures. I'll stay like this Now on to find suitable drivers for my GF2 GTS.. It seems the 40.72 is crap. |

Here's a stupid question:
Are the A7N8X socket holes 0.150 or 0.210 inch in size? The first one limits the choice of screws to 6-32, while the latter would allow me to use a 10-24 or 10-32. |

Doesn't ASUS have dimension layouts somewhere in a PDF? I could swear I saw one once for that board ....

airspirit: maybe.. in the mess that Asus call a "website". I don't know about the other mfgers, but they've got a sh*tty site to say the least.
BB2K: the holes are the same as all other Asus boards. (if that helps you...) besides i don't know WTH do 0.150 inches represent

All right, I'll translate for our non-american members...
0.150 inch: a bit less than 4 mm. .210 inch: a bit more than 5 mm. Asus re-vamped their website, but it still bites. No news there. |

From the looks of it, they are 4mm holes, i don't think 5mm screws would pass. I haven't seen any Asus mobo with 5mm holes BTW.

UPDATE:
Finally got my Epox system up and running and so far I am capped at 1804Mhz @ 157FSB. My 1800+ is still locked so I am figuring that there is my problem. Where is a good place to get some "unlocking" goop? Will be doing more tests once I get home tonight.

JTrouma: This could be two issues. First, if it is a Palamino early revision, that's all you get ... sorry. Second, if it is a TbredA or a later revision, you need to swap your NB cooler to something like a Vantec Copper Iceberg and you'll gain another 80-180 Mhz depending. The stock cooler sux, and when you pull it you'll see why. There is only a tiny bit of tape in the center of the NB to connect it with the HS, leaving the majority of it running without any cooling whatsoever (cooking).

I think the first possible explanation is probably the reason. It is an original Palimino so I sorta expected that it would cap out pretty quickly. Bummer too, I have great hopes for this chip
I have a conductive pen comming in the mail right now to unlock the Multiplier and an 85W pelt + cold plate to use on the Radeon 9700. I must say that I am rather *#&$ that I fried my really good OC Radeon and then got this piece of crap. The first one could do 380 core on just water and this one can only do 355.....I am going to freeze it then volt the hell out of it. If I am lucky, I will be able to get back to where I was with the old one or even better, hit my 400+ mark. I also just updated to the very latest BIOS. No real differences noticed yet.

@bigben2k
i was looking around a bit to see what the max FSB or the a7n8x is....seems that the 1001.C bios do 211, but the beta bios found here for deluxe users and here for non-deluxe users boosts the bios to 250mhz. congrats, you now have your 233mhz that you wanted. thanks should go to the guinea pigs at the nForceHQ forums in this thread for trying this out.
