P5N32-E, Asus's Letdown

post #1 of 30
Thread Starter 
Today, I RMA my third Asus P5N32-E board and bought myself an EVGA n680i. Each P5N32-E was bought new and returned to Asus with different reason. None of the board last more than 3 months. To isolate the problem, I even RMA one CPU and one set of RAM. Honestly, I WOULDN’T recommend this board to anyone who is thinking of OC… Yes this board is great when it is new as I have no problem getting 400FSB on my e6600. However, it is the reliability / durability of this board that concerned me.
Here is what I am running 24/7. 3.2GHz (355FSBx9). Water cooled by dual black ice radiator with Asetek extreme pump. Idle temp 29c and load temp 37c.

CPU voltage 1.35v
VTT 1.55v
MEM 2.30V (factory spec)
1.2VHT 1.20v  it would jump around once a while
NB 1.40v
SB 1.50v

1st board. RMA due to failed CMOS chip. It is one of the first batches with 0302 bios (bought on 12/24/06). I performed 8+ bios flash (via EZ flash in bios setting) since the board’s bios around Jan & Feb fixed some defect but also produced other problem. Finally the CMOS failed and I can’t post pass memory check. BTW, this board can never get the voltage right~
2nd board. RMA due to fried NB chip (<- I think). On this board, everything else except CPU was stock cooled (passive). But I do have four 12cm and one 25cm fan installed in my CM stacker case. While Asus advertise this board “designed for overclocking”, but the stock cooling capacity is nowhere near sufficient. There is no fans on NB or SB chips, they are merely rely on two small passive heatsinks. The load temp of the NB chip under OC is around 87C (without a fan). I highly doubt it is within the safe temp range. This board last three weeks.

3rd board. Bought in April and it is 2nd revision!!! For a second, I thought they finally fixed all the problem this one is going to stay in my case for at least a year… I learned my lesson and installed a water block on the NB this time. Also set a 80mm fan blowing directly to the SB chip heatsink. Several passive heatsinks were added to the voltage regular chip. Everything was running perfect for two months until I increased my VTT voltage to 1.55v. Before this, I was having problem with some programs crashes once a while. But I was afraid to increase VTT or also know as FSB voltage since the capacitors on this board looks cheap. I also worried the voltage regulator not been able to handle the job (when they are on passive cooling). After all the cooling components been introduced, I adjusted the VTT to 1.55v. As expected, the system is completely stable. Well, or shall I say for about two months… Last week the board’s voltage become unstable and would jump around in the PC Prob II. It would not boot 2 out of 3 times and the system would shut down during post.

I have been purchasing only Asus board for about 10 years and always had great experience with their product. All of their MB last more than the ownership. But I have to say this board “Asus P5N32-E” is their most severe letdown and can’t be saved! The passive cooling heatsinks are NOT sufficient for this ultra HOT 680i MCP chip. The capacitors are not 100% solid type, which is fine as long as they are all made in Japan (but I highly doubt). Asus finally realized their problems and come up with P5N32-E plus version. It has 100% solid capacitors but down grade the chip to 650i.

Mine is still going strong, although I have rigged an 120mm fan to cool the Northbridge and the RAM

It's a good board, but indeed has temperature issues. Not sure if it's Asus' application of thermal past between the chips and cooler or something else...

Check out Robilar's Asus P5N32-E Overclocking Guide. I would highly recommend purchasing two northbridge coolers. (Thermaltake Spirit II, Thermalright HR-05/SLi, Antazone AS-N1000.) Or, at the very least reseating the coolers with Arctic Silver 5. Asus does a terrible job with thermal paste, they put way too much and dont spread it out.

I know

Have read the thread... and been lazy. Maybe I am just lucky, since with the fan aimed at the NB and the RAM, every temp is quite allright

Bought mine ~1 month after release, hasn't missed a beat. Feeds 2x8800gtx's nicely. 6th asus board for me, I'm happy.

Will continue with Asus into the 45's later this year...

Don't know how they were mounted in your case, maybe a grounding problem????

Active chipset cooler does help lower NB's temp. However, by installing a aftermarket chipset cooler, VRM are exposed. Robilar did recommend installing MC-21 heatsinks on VRM. But IMO they are not enough for job. Also, half of the VRM are in a position where it can't be covered by the heatsinks.

If you are water cooling ur CPU, there are more to concern. Why? Because waterblock eliminated all air flow on components around CPU socket while aftermarket CPU cooler such Zalman 9700 doubles air flow when compare with stock cooler.

Yes, many of you had good experience with board so far. But do keep in mind that Asus has replaced this board with a “plus†version. Asus P5N32-E can no longer be found in any of my local stores. The new “plus†version has 100% solid capacitors (same as Asus extreme striker). But they replaced 680i chipset with a 650 hybrid. I am assuming that there is something they can’t get it to work right with the 680i or Asus did this simply to compensate the increasing cost of 100% solid capacitor? Even Asus said their 650 hybrid has the same OC capability as nVidia 680i, but I doubt this is true.

Honestly, if are thinking of purchase an Asus P5N32-E. Please think again~ here are some of the problem which you “might†encounter~
•Bios flash problem (keep it at minimum)
•Insufficient stock cooling on chipset
•Inferior quality capacitors
•Inaccurate voltage senor or regulator
•nVidia raid chipset sometime doesn’t post during boot.

Actually, I overlooked the title...my bad. I fixed it (and an edit in the post).

And again, regarding the board, I have no problems with it at all, and there are many others with different kinds of cooling (including water) for whom this board runs really well.

I feel for your bad experience, but it still seems an exception.

I'm on my third P5N32-E SLi as both of my previous boards had faulty bottom PCI-Express 16x slots. Regardless of this I'm still happy with the board and haven't had any issues with my third board. Every retailer gets the odd faulty batch now and then and I believe this has happened in my case. I will add that I wasn't happy at all with OcUK's RMA service, that's one company who will never see currency from me again.

I'm getting this mobo and hopefully mine would be ok! Will just get a better cooler for the NB
