Hi,

Got the bundle and its working in windows fine, having maxed out the system etc for hours on end. The only problem is that when I shut down the system at the end of the day the overclock fails on boot up the next day. Rebooting is fine. I'm running a decent Seasonic 750W PSU which should be able to handle this things. According to the power monitor on the socket, the computer is barely nearing 500W at max load. What could be causing the overclock to fail at cold boot?
 
I have the same problem no fix as yet, waiting for the v8 bios release to see if that helps
 
I had the same problem with my P5Q-Pro/Q9550.

I had to enabled load line calibration. Once i did this, it was sorted. Not sure if i7 mobos still have this feature, but its worth a try.
 
Correct, seems to be connected to a voltage problem, people report upping the vcore to way above whats needed and the problem go's however you then have the temp problem is you voltages are to high. I have load line enabled on the UD5 and do NOT have the problem :p
 
I had this Problem aswell as others and couldn't figure out what the problem was so i bought a new case and psu now I'm upto 4.2ghz stable with no issues whatsoever.

Old psu = enermax galaxy 1000w
new psu = corsair 750w modular
 
Yeah I tried upping the vcore 5-6 steps and it helped only half the time, but defeats the object :P Maybe its a bios bug, ill check if there is load line calibration option in there.
 
Will be interested to hear how you get on, i've tried 2 different PSU's/GFX cards already, and tried upping the vcore as you have, disabled turbo, plugged PSU direct into the wall rather than an extension but it doesn't seem to make any difference.

If i however after leaving it overnight i unplug the power completely so the LED's on the mobo die out and then plug it in again it will boot fine.

If i leave the PC a few hours plugged in it boots no bother, leave it over night and overclock fails.
 
Well I turned it off completly last night at the back of the PSU and it booted fine at 4GHZ this morning. It just seem to have an issue if shutdown normally without turning the PSU all the way off. So this is a bios issue I think, the board isnt talking to the psu correctly, or some PSU's correctly.
 
Hmm seems there is a new F8d bios on Tweaktown I'm too chicken to try it though :P

Info: AHCI ROM 1.20E
Fix: AHCI "VERIFY RAM ERROR"
Fix: XMP with fan control
Fix: D0 Stepping in OC
Feature: Channel Interleaving
Feature: Rank Interleaving

Also after updating the bios can we load back in the old 4ghz bundle OC settings off a USB pen profile ?

i'll give this a go tomorrow when i'm more awake but i guess it will be sunday before i find out if it worked or not :)
 
Just updated the bios and reconfigured overclock settings, all working as before and looks to be stable for the short time i've tested it, guess we wait till tomorrow morning now :D
 
I just read this thread after not visiting here for a while and also found that enabling load line calibration solved the problem of failed overclock on cold boot.

Also see later post below.

come on guys come on, its not a massive problem
you just start the system up and if your clocks are back to normal you just press del then f10 then reboot ;)

2 presses of the keyboard to fix and your back up and running, also how meny times do people shut there systems down cause its not good for them being powered on and off all the time..

in fact you do more harm to a pc the first time you power it on compaired to leaving it on for days / hours / weeks.

Agreed, the only time I have had a hardware failure was when I decided to turn the PC off as I was going on holiday for 2 weeks and thought it better for the environment to turn it off. When I came back and tried to turn it on the PSU failed. 2 weeks of electricity cost me £50 for a new PSU...

It is not just the PSU that can be a problem. The last time I switched mine back on after 2 weeks away, it was the motherboard that failed!
 
the newer bios still has issues

and i am not clocking on that one yet

the f7 has been the best so far in my opinion
far more stable

if you are experiencing issues with your bundle - please post in the customer service forum under the RMA and tech support section

i will help you out in the private forums [its much easier for me to keep track of who i am speaking to]

What are the issues?

I agree. With the previous BIOS, after weeks of having no "Cold Boot" failures, as soon as I disconnected a drive and reconnected another one, I found that I had a "Cold Boot" over clock boot problem. It is almost as though the slight change in the BIOS configuration triggered the BIOS into an over clock failure, when it wasn't. I am not the only one to find this as I have a friend in the US who I speak to regularly on TeamSpeak who has exactly the same problem.

So far I am back up to 3.9 ghz (older CPU) and with this f7 and Load Line enabled I have not had an overclock failure with switching drives around. This is with Windows XP Pro (x32) and Windows7 Ultimate (x64) RC.
 
Most likely power supply, I use a BFG 800W quad rail but I also have an OCZ 1000W single rail that I received from an RMA and the OCZ has this very issue.

The strange thing is that spec-wise (overall wattage and amps) the OCZ is superior, yet in practice is inferior.
