ASUS P5Q-E (P45) pre-view

[ssabripo]

btw, how do I tell if the replacement board is A2 or A3?

[samsonJS]

you might be able to determine based on the manufacturing date. normally i'd just fire up cpu-z, but in your case that's not going to work. there's certainly evidence on the board itself if you know where to look. i'd check near the model #.

Hey guys. So it's been a while since I've been back on here... My Q6600 on a P5Q-E (m1402 bios) was running quite well for a while, but since getting back from vacation in October I've started to notice some random crashing and BSOD (Vista Ultimate x64). So I re-ran Prime95 and was shocked to see core 4 fail after 27 mins. A couple months ago I ran it for 18 hours and there were no probs... Real Temp reports the vcore reaches 66°C under P95. However I've also been running IntelBurn Test and I can do 25 passes under max mem no prob (temps reach 78°C). I'm wondering which of my bios settings I should try changing:

Just up Vcore a bit Wongnong 1.325 to try or a bit higher, your CPU is burned in and many needed a slight bump in Vcore to regain stability

[ThugsRook]

after 8 months of OCing on my chip (and many bios revs) it still hasnt needed more vcore, but it did need a GTL adjustment. i think that might have more todo with my PSU tho and not the CPU itself.

[carepolice]

I had to increase my vcore just one notch to gain stability, after 2 month (or its just VISTA that needed increase, i was using Windows XP before)

[wongnog]

hmmm, I upped my VCore a couple notches (last one was 1.33750) but I still get P95 failure within 25 mins. Wonder if it's my DDR2-1066 that can't take the mild overclock of DDR2-1080. I'll either try upping VDimm a bit, or clock down to 8x400 so I'm running at DDR2-1066.

[ssabripo]

so strange.
so I just received my replacement board, and it is an A3 rev. Same exact settings as before, at 1.283 and it is stable!!!

I'm currently running 456x9 (4.1ghz) at 1.293v, and all is perfect. I guess I'll stick with this.

[Leeghoofd]

Great Ssabripo, can you post a picture of the box like in post 528... so to determine in the shops which one has got a new NB rev

I tried replacing the mobo with a p5q deluxe and everything is working fine again. I have no idea what the heck happened to the board, it was just like instant death.
crap...looks like the same thing is happening to me!!

I thought it was a CPU wolfdale Vcore issue, but this morning it rebooted again!! and now it wont POST, although it powers up. Fans are running full speed too. crud, this sounds like a mobo going bad, right?

I got my board back from RMA, the problem is still there. I don't see anything on my monitor, but everything powers up. I bought a p5q-deluxe to hold me over during the RMA, everything works fine. What the heck!

hmm...i dont know man. Mine is now a A3 rev, and it is running really nice...i'm super stable at 4.11ghz (1.29v), will try to go to 4.2ghz on same vcore tonite hopefully:

[ssabripo]

here it is...currently running 10min and counting of Orthos...so far so good. If it stays stable I'm keeping this!!!

Hello Everyone,

I have been reading the forum and would like to get some detail instruction on how to flash the bios.
Here is my spec for the computer parts I have order and its just arrive this morning.

This is going to be the first OC for me and I dont understand all the bios setting. Hoping someone could give me a bit of advise. I am not into maxing out all the hardware, but just want to OC to 3.8 - 4.0Mhz stable.

P5Q-E
Q4550
OCZ GameXstream 700W
Xigmatek HDTS1283
4GB OCZ Reaper 2x2GB DDR2-PC6400 800Mhz
4GB Crucial Ballistix 2x2GB DDR2-PC6400 800Mhz

[Leeghoofd]

Well if you think that 4Ghz is normal I would suggest you to rethink ya strategy... as 470FSB is not a just put in the bios settings of the template and let her rip... Plz read up on some Oc'ing techniques and run the rig first at stock... see how ya cooler performs, what max FSB you can get, determine the max speed of ya ram...

I just want to avoid you comig gback in here and start to flame that the mobo or other parts are/is crap, as it could also be you being the weakest link...

[NODO-GT]

hi,
Here are some results on my P5Q-E
Crucial BallistiX Tracer Micron D9GMH 2x1GB
Intel C2D E8500 (C0)
Everything Air Cooled.
NB Stock Cooling + 80nm Fan

618.07MHz FSB
http://valid.canardpc.com/show_oc.php?id=447144
749.6 MHz DDR2
http://valid.canardpc.com/show_oc.php?id=447150

I'm interested in the limits of this motherboard. what is the highest FSB reached?

[bot@xs]

i second that.
i am at 450 now, tryin to get it stable and so far it holds up.
i thought i saw someone at 500mhz fsb. how did you do that?

also, did anybody have problems with NB cooling. mine seems to run hot.
it's at 45 degrees and seems to be the limit. i cool the cpu with a swiftech h20-200 compact. keeps it nice and cool but leaves the NB with little airflow.
i thought about watercooling the NB too but then the SB and the PWN would be left high and dry.

specs:
Intel Q9450 @ 3.6GHz - Swiftech H20-200 Compact
ASUS P5Q-E Rev 1.xx/ Chipset Rev A3
OCZ Platinum 4x2G @ 1:1 450MHz/ 900MHz Cas 5-5-5-15 - i wanna try to run them at Cas 4
EVGA 9800 GT
Raptors
oh, and it's a rev 1 board but with a rev A3 chipset

it's running at 450x8 for 3.6ghz now, loading all cores with boinc 24/7

The guy I bought my E8400 from reached this on his P5Q-E

http://valid.x86-secret.com/show_oc.php?id=380746

645,92 MHz...

[carepolice]

on quad 500FSB +/- 10 is wall, atleast on my situation

[Leeghoofd]

The guy I bought my E8400 from reached this on his P5Q-E...

I would contact Chrisch, just to ask which settings he was running for that 1.2 Vcore 4ghz shot (namely FSB term, CPU PLL, GTL's) I hope for you he recalls them... Chrisch is a madman and a master tweaker, he get's a kick out of high FSB and was a pleasure to work with when we started to test alpha biosses for these boards... I'm pretty sure he will reply you asap...

[Ket]

Why is it whenever I release a new MBIOS for the P5Q Series a bunch of P5Q threads are revived?

Haha, so you didn't know it was him when we were talking in my other thread about my CPU?
But I have it stable at 8x500, 1.200V on CPU read out by CPU-Z...the key was to set FSB Termination Voltage to 1.28Volt, I had it at 1.24, 1.26 and 1.30, all crashed after 3h, but 1.28V is fine...but I read that >1.22V might kill my WD Raptor??

@Ket: it hasn't anything to do with your BIOSes, even though the 0704-version you modded works very good on my P5Q-E, but I allready had these problems for a few weeks now, but I had no real time to check what's wrong there...

[Leeghoofd]

Because it coincides with the release of a beta or final from Asus ? and people want to see what has changed for better or worse ?

Good one Grossmeister keep it up now !

I'm testing 1.22V FSB Termination Voltage now, reduced DRAM Voltage to 2.00V, too, saw some charts where 2.00V in BIOS with Ket's BIOS results in 2.09V measured with DMM, seems like it works so far, 40 minutes of orthos without crash...we'll see if it works or not...

[CryptiK]

Here is a picture of A3 rev. board it came with 1201 bios.

Thanks cchilb.

I think the first 2 digits indeed represent the manufacture date. first 8 for 2008 and second for August. So A3 boards would have serial greater or equal to 88.

It would be good if boards with serial codes starting with 88 and on were A3 revision, I just got my replacement P5Q-Deluxe which was a new board from the supplier, and it has the code starting with 89, but I have not yet pulled apart my system to see if its A3. I was just going to sell it but now I'm inquisitive as to whether its an A2 or A3 after reading this.

They can find all that out in the mBIOS thread, so my question still stands, why do so many P5Q threads get revived whenever a new mBIOS pops up lol.
