Hi

I recently purchased the following overclocked bundle :-
1 X Intel Core i7 920 D0 Stepping (SLBEJ) 2.66Ghz overclocked up to 4.00GHz! (Choose overclocking option above.)
1 X Gigabyte EX58-UD5 Intel X58 (Socket 1366) PCI-Express DDR3 Motherboard
1 x Corsair XMS3 6GB (3x2GB) DDR3 PC3-12800C9 (1600MHz) Tri-Channel
1 X Noctua NH-U12P SE1366 CPU Cooler (Socket LGA1366)

I payed for the 3.8ghz overclock and I think the memory was substituted as the normal patriot memory was out of stock.
I have a small issue it seems though, When I load the OCUK overclock and do a cold boot, the overclock fails and then it boots with default values, if I restart and reload the overclock it boots up ok and it seems to run fine with no bsod using prime 95 for a couple of hours.
So you see I am at a bit of a loss at what is causing the overclock to fail at boot level. The pc seems to start after I press the power button and the fans spin up, then they stop, then start again, then stops then it boots.

any ideas of what I should be testing to find the issue? I am a bit of a noob when it comes to overclocking, thats why I ordered the bundle.

p.s. the gear in the sig needs updating was my previous machine, still using the psu and sound card though.

I have noticed now also, that I have a high pitch sound eminating from my case slightly while everything is at stock.
When the overclock is set, the sound is louder and more prominant. It seems to be coming from the psu area, I can also hear the sound through my headphones and sort of changes pitch when I move a web page window etc in windows enviroment.
Could this be a reason why my overclock is failing at boot? Maybe there is not enough juice going to the cpu when I do a cold boot?

it is a antec quatro 850w.
 
I have replaced my psu, and I think it might have solved my boot overclock warning. fingers crossed ;/

I have dropped my BCLK to 181 to give me 3.8ghz overclock for now, as under prime my temps are hovering around 84. I am not sure if its my case though, its an antec p182 with the three fans it originally had.

Maybe this case doesnt have enough air flow with these fans to cool an i7 overclocked?
 
Well the high pitch whine I was getting has gone, which at least is one thing.

I notice my setting that Overclockers set up for me, has the Qpi/uncore voltage set to auto, is this usually done in an overclock, I read somewhere saying it needs to be a set voltage? Maybe this is a contributer to my failed boot overclock then.

Its an odd thing because my chip flys with all the tests in windows and seems stable.

do you have access to a power supply tester?

all bundles go through 8 [minimum] hours prime + 1 hour linX
as well as being tested at 4ghz regardless of them being 4ghz/3.8ghz

the voltages are fine
please do not adjust BIOS settings without consulting me

if you call system support and ask for Rich

i will help you out as much as i can :)

I dont have access to a power supply tester I am afraid, the good news is, that the replacement psu I bought might of done the trick.
I have started my pc from cold this morning and just now after I came back from work, and it started up on both occasions, no fans spinning then stopping then booting, with the boot failure at all. Touch wood!
Its seems stable in windows after running prime and intel burn test for a few hours last night and I have had no need to play with any bios settings.
Only thing I am slightly concerned about is my temps getting to 84c on full load, I read a lot of people saying its not safe :/
