I am getting the blue screen of death from this newly acquired bundle.

I can get it to BSOD every time by kicking off a video render. It normaly fails after about 5 minutes. I have checked the temps and they are fine (42C when idle up to about 60-65C under load. I reduced the clock speed of the processor to 3.8Ghz and I can't get it to fail at these settings.

I know that it is only 200mHz, but i have paid for the full 4.0Ghz overclock and three of my friends that have these are all running at full speed.

Any suggestions?
 
If it's stable at 3.8, not stable at 4.0, and you paid for the 4.0 overclock, I suggest you re-post this in the RMA and technical queries section. It sounds like an RMA.

Well, I did post this in the RMA and tech queries last week but no-one has got back to me...

I have a Nvidia GTX 285 and an OCZ 600W PSU. I am pretty sure it is not the PSU though as I originally had a 420W PSU which was working OK (apart from my OC problems) and upgraded because I though that this may be the weakest component.
 
i have reccomended on here many times that people use a 650w or greater psu

i have had successful runs with it on a 400w corsair but that was with an ati 3450
 
Well, this PSU is advertised as an SLI PSU so I would have thought it would have plenty of power. The fact that I ran the same system on a 430W PSU strikes me as an overclock problem and not a PSU problem.

If Overclockers ever get back to my RMA query I may consider upgrading the PSU but four of my friends now have this exact config and none of them are having the problems I am.
 
OK, well I still haven't heard anything from the OC staff regarding my query in the RMA section that I posted on th 17th. If I was feeling cynical I would say they are waiting for the 28 days distance selling minimum to be reached. Not too impressed with this although they did handle a noisy PSU problem I had very efficiently. I am going to be seriously un-impressed if OC do not get back to me by the end of today.

It seems if I turn off hyperthreading then it makes it a little bit more stable athough I managed to still get it to fail about a quarter of the time. The problem is that this slows down the video render speed about 20% which is quite a lot when the whole reason I bought this rig was to speed that up!

:mad:
 
........ I'd pick up the phone & call them or send a webnote - these guys don't want to sell you something that doesn't work.

ocz power supplies are having problems , how many customers with problems using a ocz

problems

I've just bought one of these bundles, and i've had loads of problems with it, it just keeps crashing and freezing. I've tried running it on windows vista 64bit and windows 7 64bit with the same problems. I have the 4ghz bundle and my setup is:

OCZ ModStream pro 600w PSU
Gainward NVidia GTX 295 Graphics Card
2x OCZ 60GB SSD Drives in RAID 0

I was thinking it may be my PSU not powerful enough, but i have taken the graphics card out an used an older Gefore 6200 which uses hardly any power, and i am still having the same problems. Any help and suggestions would be greatly appreciated.
 
Someone earlier mentioned a lot of these problems seem to be with people using the OCZ power supplies. It wouldn't be something inherently flawed in that 600w power supply would it? (possibly to do with the bit of it powering the mboard/chip, which would explain why changing the graphics doesn't help, as thats handled by seperate power connectors or they are on different rails or however it works - im no expert on power supplies incase you didnt notice).

Anyways, my point! -> It could be that the i7 overclocked that high isnt getting a stable enough current with that PSU, which causes the stability issues.

I saw on here earlier today a post from a Don saying to not use a 4-way extension lead and that the state of the wiring in your house causes these crashes. Can't seem to find it now though, and I can't remember the exact wording so my searches aren't finding anything either.

I'm sure you won't have any problems, as they're tested before they're sent out, but just in case, it might be something to bear in mind if you do experience problems.
 
does anyone know how to get my overclocked settings back? I have cleared the CMOS settings to test the stability on the standard settings, but unfortunatly it hasn't made any difference :( I was told there was a profile saved on my mobo but i can't find this.
Also is there any way to test the voltage that is being fed to the CPU to see whether this is constant and it is infact that the powersupply that is my problem.
 
press f12 to bring up the overclock profile


all bundles go through 8 hours minimum of prime 95 then a 500 line LinX test
i suggested not to use multiplugs as it seems to be a cause of issue with the problems i have heard

going through trouble shooting on the phone, i suggested to a customer to try with no multiplug - it made his system stable

the wiring in the house comment is because i live in a very old house and my personal system suffers because of it

a good psu is essential to run an overclocked i7

in my opinion the psu is the most important component in any system
 
I've tried it with no multiplug but with no joy. I'm going to borrow a power supply from a friend and give that a try. If a different power supply doesn't work then i am completely out of ideas. Also, when i go to MIT in BIOS, it says that the CPU frequency is only 3.8GHz, however i padi for 4GHz, does this mean it is only overclocked to 3.8? or will this increase under load?
 
It could be that the 3.8 is without the turbo option on the i7, as that would add a single multiplier (if your running 19x200) to make up the 4Ghz. Should be a toggle option in the bios to enable or disable it.

try stress teesting it , i think it activiates turbo when needed and clocks at 4ghz
