I have actually clocked it down a few notches from what I originally found stable (in my sig), but it hasn't really helped any. I have memtested my RAM to hell and back, so I doubt it's something wrong with them. The system also passes endless hours of prime without a hassle. The thing is, it's completely stable when it has booted into Windows, it's only that first cold boot that makes it BSOD. Also a thing I noticed, after I flashed I lost half the pull-ins of both channel A and B. Now I only have pull-ins for phase 1 and 2 for each channel.

I had a similar issue with the phases on my board - sometimes i'd only have 2 phases, sometimes 4, sometimes 5 - sounds like your bios chip may be going bad or maybe just a bad flash. Try re-flashing it again.

Well lo and behold, all phases are present today. They were not there yesterday after I flashed! Ah well, I'm gonna keep my eyes on it and see if it's consistent.

I'm trying to re-create my cold boots, but I'm not having any luck. Looks like the system needs to be powered off for some time to actually make it BSOD on boot, making the wording "cold boot" quite literal :P

Mine is doing the same thing here. I have my Q6600 in right now. We might need to pull the battery for like ten minutes while clearing the BIOS. It kinda of seems like phantom issues.

if you guys will stop tweaking out all the mem setting you might regain stability.

DRAM Static Read: DISABLED
DRAM Read Training: DISABLED
AI Clock Twister: AUTO
Pull Ins: DISBALED

tweaking out those options can kill cold boot stability, dispite 24 hour stress test stability

and chill out on the PL

Thanks, I will definitely try these things. But why is this cold boot thing an issue? I mean, why does it work after it isn't... "cold" anymore? These things just don't make any sense to me. If anyone could explain, I would greatly appreciate it.

[truehighroller]

I thnk it has to do with Caps..

[truehighroller]

Luci5r or the other guy with the issue now. Have you guys tried this setting it to performance thing yet to see if it works like he says it does?

Bah, updated to 1403, and my system still BSOD's on every cold boot. It's the same every time. It posts as normal and starts loading Windows, where it will BSOD after some time, then reboot and boot as usual. I'm just waiting for my Windows install to go bad on me. Extremely annoying!

1403 sucked here. As to the pullins being missing, I had to boot to bios after a cmos clear, load defaults, then shut down/clear cmos/pull battery...yada yada, took me 3 times doing that with 1403. I think that bios should be scraped.

I found 1402 from pmp the most stable for my setup.

@ True; Mine will boot higher and run higher but i can't get it stable with good temps/ low volts. I think maybe a better bios or time to move to another board but I like the layout for my hardware. Heck, with my voltage I only get 43c tops in IBT, but as I have a 32bit OS its only sorta half strained. Prime 10k only gives 39c load. This chip should do lots better.

someone have a download link to 1402?

cold boot problems have been with us for a very long time, im pretty sure Abit introduced it as a problem tho

i think cold boot is very different from a reboot, perhaps something to do with default cold boot settings. might be the reason why P45 forces a shutdown/cold boot restart when changing certain bios options. chances are those same certain options are the cause of the P45 dead cold boot syndrome.

[jagt]

Yes you're right there, I've heard about cold boot issues for many years, but I've never experienced it myself. And I've had various boards from Asus, Abit and DFI over the last few years. I've disabled DRAM Static Read Control now, so we'll see if that makes any difference tomorrow morning when I boot the system.

I'm using 1403 with no issues whatsoever. Having moved from a DFI. Shutting down immediately after fllashing, unplugging and clearing cmos and then loading default values before tweaking have become habit, although now that I think of it, I didn't remove the battery this time as I had to do with my Lanparty SLI-DR. I guess I got lucky or something.

Okie, I have this rig:
P5Q Deluxe, 1403 M BIOS, Q9550, 2 Gb PQI 800Mhz RAM.
Zalman CNPS9700 cooler.
So far reached stable 440*8,5 3740
Tj max 80°C on small fft prime.
Proc @ 1.35 V (any less results in Prime error)
NB @ 1.2V
Dram 1.9 V (def 1.8) (timing instead 5 5 5 15 - 6 5 5 15)
What steps can you suggest to take to get stable 4K?

[Leeghoofd]

First thing I would advise you is to get a decent cooler ,the Zalman doesn't cut it with a quad@4ghz... and/or you check if the IHS of the CPU is flat and check the zalman too... Can your ram handle 940mhz ? Are you also aware when running a 1:1 divider you get a pretty high PL....I think on ya current hardware 450FSB is already nice (3.8Ghz) with the ram at 900Mhz...

Can you fill these in plz :

CPU Voltage: 1.35
CPU GTL Voltage Reference (0/2):
CPU GTL Voltage Reference (1/3):
CPU PLL Voltage:
FSB Termination Voltage:
DRAM Voltage: 1.9
NB Voltage: 1.2

[a31666]

Damn, i thought this cooler will do while looking what to buy.
About flatness, i think flat. Now it is colder in room, 4870x2 is idling, and temps get only as high as 73 (same Prime still running from last post, stable). But i will check that later just to be sure.
About RAM, it was cheapest one (they had not what i wanted, so i took this to have something while waiting for better) Any recommendations on which RAM to aim? Sitting on XP, so 2Gb enough atm.

Are you also aware when running a 1:1 divider you get a pretty high PL...

Sorry for noob question, but what that means? Some sort of latency?

CPU Voltage: 1.35
CPU GTL Voltage Reference (0/2): Auto
CPU GTL Voltage Reference (1/3): Auto
CPU PLL Voltage: Auto
FSB Termination Voltage: Auto
DRAM Voltage: 1.9
NB Voltage: 1.2

I love my Gskill and mushkin rams but they are all 4gb kits... snoop around here for brands, think most use PC8000 ram

Sorry for noob question, but what that means? Some sort of latency?.

Indeed in brief it enhances bandwith and drops latency... the lower the PL value the better ram performance you can get... so with ya FSB in sight a ram kit that does 1080mhz or more is advised...

CPU Voltage: 1.35
CPU GTL Voltage Reference (0/2): Auto
CPU GTL Voltage Reference (1/3): Auto
CPU PLL Voltage: Auto --> DANGEROUS : try 1.56
FSB Termination Voltage: Auto --> DANGEROUS : Try 1.26
DRAM Voltage: 1.9
NB Voltage: 1.2 --> try 1.24[/QUOTE]

Most board overvolt big time with an OC and auto voltage setting... so plz adjust and try to find the lowest working value, these are a good starting point but could be lowered... if you set these try a slightly lower Vcore then too , eg 1.34... and test again... I'm pretty sure with some good tweaking all the voltage options (including GTL ref's) combined with a beefier cooler you could lower ya Vcore for sure...

Good luck sir

[a31666]

Thanks for reply mate, now checking new voltages - seems stable so far.

[FabricioGS]

Hi folks.

My board just arrived and it came with the 0704 bios but I'd like to know wich one is the best bios so far (specially for overclock)?

[ShooterD]

is 1.36vcore on 45nm quad safe for 24/7 use on air?

[Singh400]

0803 in my opinion.

[douirc]

just updated to 1402 and can now raise fsb to 475 vs previous wall of 450 on q9450. also helped with my e7200 from 500 wall to 540.

[platojones]

is 1.36vcore on 45nm quad safe for 24/7 use on air?

1.36v would be the absolute max vcore (according to the Intel datasheet). If that is your BIOS setting, it will actually be between .2v and .3v lower as measured by CPU-Z. And CPU-Z is what most people rely on. Whether it's safe on air depends on how good your air cooling is...but my guess would be if you keep the max sustained core temp (read by real temp or core temp) below 75 C, it should definitely be fine.

[rsnt]

I just got this board and the installation went fine, im just completing the rest of software installation. Everything is going smooth so far except for one weird thing: Is it normal for this board to drop the multi by itself? LOL I found it to be funny, I have an E6850 and CPUz showed it at 2.0ghz and multi down to 6...

I think theres a setting in Bios i need to change dont I? I have 1306 for BIOS.

EDIT: one more thing, my memory setting in CPUz arent showing either. Nothing but size.
