ASUS P5Q-E (P45) pre-view

[thehinge1]

My revision 1.01g P5Q-E with 'A2' revision chipset sucked big-time!

However, I have a pair of A3's now and they are both working perfectly

My 'rig time' has been a bit limited lately, but thus far have the E7200@3.8GHz/475fsb/ddr2-1140 on 5:6 with CPU PLL at 1.52, 1.22VTT, and NB at 1.22v as well. I can probably run the NB at or below 1.20v with more GTL tweaking (at 0.580 now for NB ref). Currently running 5-5-5-18 at PL-8.

The E8400 is at 4.005GHz/445fsb/ddr2-1068 at 5-5-5-15 PL-9 (I think, might be 8). CPU PLL 1.52, 1.16VTT, NBv 1.18 as I'm still playing with FSB/RAM.

Seems to be XP64 likes more NBv/slightly lower NB GTL ref than XP32 on the dual-boot E7200 rig. That's all for now

thehinge1,

would you let me know the revision of your A3 boards?
All boards in my area are rev. 1.01G.

[Leeghoofd]

Could you take apicture of the sticker on the outside of the box plz liek the one below plz

[supermario]

Thanks Leeghoofd.

The shop won't be happy with me taking pictures in store
Instead, I have copied down the serial number.

Serial Number: 86M0AC692351
Same Model #: 90-MIB4G0-G0EAY00Z

I think 86 means manufactured in 2008 June.
P45 A3 production start in July so it cannot be A3.
Maybe wait longer?

[Leeghoofd]

Model (of piccie) I got was already with 0803 bios and the smaller caps at the first PCI-E slot (will resize picture later this evening still at work) we need to figure out these codes to determine which chipset rev is on it

[cchilb]

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

[supermario]

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.

[thehinge1]

Both boards are ASUS revision '1.01g' just like the 'less-than-consistent' (and despised) first board. The shipping bios on both boards is 1201 dated 08/05/2008 as they POST so they were at least made after that date, so they quite possibly were made in August supported the year/month theory.

cchilb - you get your board from the egg? Looks like we are 2 digits apart.

Note: 9mm 124gr.+P GDHP in photo is in case I ever see my first P5Q-E again, that sucker is toast!

thehinge1,

[cchilb]

Ordered on 10-22-08 from the Egg, it shipped from Memphis.

It has a lot of difference A2 to A3?
mine is A2

[thehinge1]

I have had both A2 P5Q-E and A2 Biostar TPower I45, my A3 P5QE's are much better in terms of running much lower voltages in BIOS setting at the same FSB I ran on the A2's. My A2 'E' was a dud no matter what BIOS I tried, and the I45 was ok but the voltage granularity on Vcore (among other weird BIOS limitations including last mfr update on 7/10/08) did it in for me when I got the E0 8400.

There are some great A2's out there, I just didn't get one.

From what I have read the A3's from various manufacturers are hitting some really high FSB and doing it on reasonable voltages, seeming to be in line with what I have experienced. If you are happy with yer A2 I'd stand pat

If anyone has some great info on the A3 revision please do chime in!

Anyone got a pencil vdroop mod for this board? Had this board for about 2 weeks, it's set at 1.406 in Bios, 1.376 idle, 1.352 under load. This is messy as hell. Running a e7200, which isn't clocking very well (Set at 3.6 (400x9)for those voltages, no post past 420 FSB). SLAPC batch #Q827A702, Ket's 1306m bios. Any help would be appreciated.

[Leeghoofd]

Any particular reason you do not want to use the LLC function Butcher ? Works pretty fine here 1.256 set in bios, idles at 1.248 and is 1.256 under load on my DLx's , the E load is a tiny bit less...

[StalkingButcher]

Hey Leeg, it was causing BSODs for me while running Orthos. When I was overclocking I had LLC on and it would BSOD within minutes, then I turned LLC off ( saw Zeus' post) and without changing any settings, including vcore, suddenly I was OCCT stable one hour. So I've kept it off.

[Leeghoofd]

That LLC issue was resolved with 1406 bios on my E board... beforehand indeed it didn't function at all...

[StalkingButcher]

Okay, thanks. Will update the BIOS again.

I think mine is an a2,86xxxxxx sn.It has been great,i have my 6750 running at 4ghz(500fsb) fine in this board.

How do you find out what rev the chipset is btw?

Wich bios your board came whit?

If i remeber right that newer revisions got 1xxx bios already

[gugle]

how I can to improve these values?

has anyone experienced a need to boost Vcore after a while?

strange, but a couple of days ago my computer became completely unstable after 2 months of running super stable....random restarts often, and a couple of restarts that would end up in non-reboots; had to turn PSU off, and start over.

I bumped Vcore from 1.28750 to 1.29325 and a little better but still rebooted. Then up to 1.3000v, and almost good but had two more reboots. Up to 1.3250 and now it is stable again! I didn't want to run that high of a Vcore, so I went back to FSB = 430 (3.89ghz), and put the Vcore down to 1.2835 and now it is running perfectly fine.

anyone notice this? the e8400/8500 thread reports several episodes of this on several types of boards.

[Leeghoofd]

Sure it's the CPU and not one of ya rams capping out ? Many users required a bit more Vcore after a while but we are not talking going from 1.29 to 1.32, but more from 1.29 to 1.295... Your Vcore requirement seems a bit steep... did you update the bios or changed any other values ?

no..nothing changed. It just one day started rebooting like crazy.

I posted this on the e8400 thread, and it seems like indeed it is a CPU issue as several people have reported having to increase Vcore substantially on the wolfdales after a while. strange!

oh well, I'm running 3.9ghz @1.28 pretty stable, so I'm gonna try that for a while...I don't want to run 1.325 to be able to run 4.01 ghz again; not worth it in my opinion.

[gugle]

PLL is not high?
comment that the few PLL ends with the CPU

I had a second p5q-e crap out on me last week, it was a RMA replacement "newer version" board, 88M0A something.

I was just watching highlights on nfl.com, computer instantly shut down, restarted, but would not post ever again, although it would power up. 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?
