Why is it when I set the NB Vcore lower than 1.45V, my PCI-E link width is x1. When I set it to 1.45V, it stays at 16x.
I would like to use 1.25V on the NB to keep it cooler but it keeps the PCI-E width at x1. Is there a way around this?
Thanks

That has to be a bug with your board. Do you have the latest bios?

With his boardOriginally Posted by dnottis
, I've yet to see a P5B-DLX not have this issue. I have to set mine @ 1.45 / 1.55 to maintain 16x speeds. 1.6, auto, 1.2 all have 1x speed bug. Pisses me off
Nothing anymore
The p5b is athat way.
Damn it, I just wish I could use lower voltages on the NB.
the new Gigabyte DS3 3.3 does that too *shakes fist*
I just got my p5b-deluxe from newegg as refurb. Mine does the same thing. My p5b-e never had this problem. At 1.45NB it workd fine though. Ran Aquamark3 to confirm it's actually 1x. 67 fps vs 178 fps - so ya I guess it is really screwed up.

Mine don't do x1 issue never, I tested with all NB voltages, 99-110Mhz PCI-E, other voltages and FSB, but aways x16.

I also have a new P5b-dlx C2 and i had the same problem with x1. I set in Bios PCI-E Speed to 110 Mhz and the Problem was solved !

^Thanks, that worked!
Is anyone else's northbridge hot? I can't touch my northbridge for more than 4 seconds.
step one: get a fan blowing over NB heatsink
step two: don't try to hold your finger against something hot. you might get burned
My DS3 rev 3.3 NB gets hot, so I used masking tape to put a fan blowing through it. Cool to the touch. I didn't bother replacing thermal grease on SB or NB heatsink as neither get very hot.

I have this issue as well. But if I set my NB vcore > 1.45 it does it, which limits my O/C, and pisses me off.
PCIE freq adjustment didn't help me. Interestingly enough it only started doing it after I flashed to 1004.

My P5B-Dlx C1 rev. 1.03G does not have this problem ever.....bios 1004, PCI set to 101, All voltages to auto except DDR and Vcore.
normally raising voltage will have that 1x problem
they all have that issue some way or another....people that say they haven't had it haven't pushed the hardware
havent got rid of this as well, every now and then she just drops to 1x and i gotta fiddle in with the bios to get her full speed back. otherwise such a nice board though...

So using an older BIOS won't even remedy this? Im on the latest one 1004.

no!
Exactly!
O, this issue has been around since the first P5B-DLX, apparently a BIOS update wont fix this.
Nothing anymore
Please tell me how to test, because never mine switch to x1

Just check CPU-Z.
Far right shot at the bottom shows the PCI-e link. The link width drops to x1and I confirmed with Aquamark3 I dropped from 178 FPS to 67 FPS - so it does in fact change.

I know how to check this, the "problem" is that the motherboard don't switch x1 never, any voltage, FSB, PCI-E Frequency

Anyone still get the double restarts on a cold boot? I do and I'm using 1004, I thought this was resolved?

I only get double boot restarts when the power is physically cut off. Doesn't happen when I leave the power plugged though if you know what I mean.
Last night I cleared the CMOS, reflashed 1004 again, cleared CMOS - then setup my BIOS. So far I haven't had a double restart since. Checking forums, someone mentioned this might fix it - I had already done it so we'll see.

This pci-e 1x prob is what i dislike most about this board. After so many months i can't stand it any more.
A P5N32-E SLI will take it's place when i have the time.
