my current PSU is


1000watt PSU: Newton power supply ltd
model: N1000p-00
ref: NPS-1000AB B

when i try and overclock i get freezes and lockups and the odd BSOD

when i put it back to stock it runs ok

the psu im using is the one i got with the old alienware computer and is like 3 coming on 4 years old. not sure if its the psu that is the problem ?

current parts are

MSI ATI Radeon HD 6950 OC Twin FrozR III Power Edition 2048MB GDDR5 PCI-Express Graphics Card with Dirt3 & Deus Ex PC Games
Intel Core i5-2500K 3.30GHz (Sandybridge) Socket LGA1155 Processor - Retail
Gigabyte Z68XP-UD3 Intel Z68 (Socket 1155) DDR3 Motherboard
Seagate Barracuda 7200.12 1TB SATA 6Gb/s 32MB Cache - OEM (ST31000524AS)
Corsair Vengeance 8GB (2x4GB) DDR3 PC3-12800C9 1600MHz Dual Channel Kit (CMZ8GX3M2A1600C9)
Corsair A70 High-Performance Dual Fan CPU Cooler (Socket AM2/AM3/LGA775/LGA1155/LGA1156/LGA1366)


also i will be looking for a new case as the one i have Atm the CPU heat sink don't fit and i have to have the door off for the cpu heat sink to fit :D

so if there is a decent case and PSU bundle that would be better.
 
How big is the overclock you are applying? it could be unstable and thats what you are experiencing.

Start of small and work up, testing with Prime95/intel burntest as you go.
 
i put it on 4.2 and it didnt work i even tryed the motherboard auto boost which is called smart 6 which put it on 4.47, the cpu is very cold because of the cpu cooler.. so i dont understand.. even my GFX card when i look at it the voltage is on 0.900 is that normal ?
 
Smart6 doesn't work well, plus it alters the bclk from 100Hz which isnt good.

Do it manually in the BIOS, use a 40X multiplier and then test, manually set the RAM to the correct speed/timings and voltage also.
 
im not using Smart 6 atm didnt like it :D

what are the correct speed timinga and volts ?
what about the CPU volt as it says its on 0.900
 
The timings and voltages of the RAM are written on the side of them on a label.

Disable turboboost/speedstep and it will always be at the value you have manually set it too.

Can you do this,

Make a note of the reported Vcore in the BIOS at stock/default settings.

Change the multiplier to 40X and then save and exit, then go back into the BIOS as it restarts.

Has the Vcore automatically changed to this sort of value? - 1.300v-1.325v
 
Seems a tiny, tiny bit high, but at least its working automatically.

Now test the stability of this 4GHz overclock by using Prime95 for a few hours and maybe running intel burntest for multiple runs, you can also have open CPU-Z to check the clock speeds.
 
Set it to 20 runs.

You can monitor core temps of the four cores using Realtemp (there will be a 4-5c variation between them, thats normal)

Then when you think you are bored testing it for stability, set the multiplier to 42X.

im using coretemp atm and its saying that the temp went to 74 the highest core.

Hmmm,

That seems a bit high (isnt there a variable resistor or something that comes with your heatsink to alter fan RPM speeds? sure there was?)

But it could be that you are using a case that just sucks (not in a good way:D) so the ambient air temperature inside is higher than a "performance" case.

Try re-fitting the heatsink?


For reference I get 60C at 4.5Ghz using either a Titan Fenrir or a Antec 920.

tryed refitting it..one of the thumb screws was broke..i did email OC and they said it would be fine with 3..

the heatsink is always cold like no heat at all :( ill try itagain i check the heat with my finger :D
 
You did apply thermal paste (if it didn't come pre-applied?) did you use a pea sized blob and let the clamping pressure of the mounting mechanism squeeze it around.
 
can you spec me a case please m8 as the one i have the A70 dont fit and i need the side door off.. cheapest possable please.. as long as everything fits :D

thank you.
