I have just installed the Corsair H70 this morning and am amazed at my load temps. Installation was a breeze and it has dropped 10c from my load temps (went from an Akasa Freedom) :eek:

The only slight problem I have is that now I am getting good temps I have decided to ramp up my overclock. Now standing at 4.01ghz with the following

Intel i7 870
Gigabyte UD2 P55
4GB Corsair DDR3 2000Mhz

Multi - 21
Bclk - 191
CPU and VTT Volts are 1.4v
PCI Locked at 100Mhz

Turbo and Volt C-State Managements are all disabled

The system boots fine but when I start encoding using x264 it crashed out after about 3 minutes. No blue screens or lockups though.

My temps were all looking great so it's not a heat issue.

any tips?

Thanks!

hmmm i use xilisoft to encode my stuff, and the core stuff goes up and down, generally when there is too much heat it uses less cpu power and the temp goes down, then it ramps up the cpu power and flux all the time when i convert.

maybe you have a problem in that area, i.e. you oc is causing the failsafe to stop working. i.e. causes the flux on my pc.


edit your problem might be software related, but not sure as you obviously used this program before with the other cooler.

could be related to the power still... as the h7o might use a lot more power than the normal fan, hence killing the system.

If it's crashing while transcoding it probably is not stable. Maybe wise to run prime or ibt to check the stability of your overclock.
 
Multi - 20
Bclk - 200

This seems to have done the trick. Encoded for 10 minutes without crashing, I shall try overnight to see how it gets on.

Settings above set the RAM to 2000Mhz which is what it's rated for. Temps never went over 60c using coretemp so fingers crossed for tonight.

If it's stable I shall be one happy chappy
 
Some boards don't like running the 21 multi on i7 chips, hopefully changing to 20 will give you better stability. 1.4v seems pretty high though.

Click to expand...

fingers crossed, its definately better than it was

Intel say the maximum without any long term damage is 1.4v so I'll see how I get on tonight and then maybe start dropping tomorrow
 
No offence to you but if your overclocking properly arent you ment to up the FSB or multi and if it fails you bump up the voltage? Not whack it on max voltage so it should be stable :S
 
The reason I am doing it this way is because I am sat at 4ghz. I'm assuming that this overclock puts me on the wrong side of 1.3v anyway so going with intels safe max and working backwards seemed like a good idea to me.
 
im only going to say this once

we tried overclocking an i5 to 3.4ghz on this board and out of the 10 we batch tested, 7/10 of them blew a mosfet when overclocked.
out of the other three two set on fire and one actually passed. this was with a vcore of 1.3v

the board is not designed for overclcocking. it doesnt have the correct cooling to cope with an overclocked i5 let alone i7

pumping 1.4vcore through that i7 is all well and good because it will accept it.

but you will also be RMAing the motherboard very quickly.
 
while I decide on a new motherboard (or maybe wait till the mainstream six cores hit the market) I am going to run the highest OC I can using stock volts. Do i assume that this will be safe and not burst into flames?

Just reset all BIOS settings, put the CPU to 3.6ghz on stock volts and everything seems to be running fine.
 
As long as your passing prime and the like and its stable then go for it.

As rjkoneill said, that boards not realy designed for overclocking and will (in his words) crash & burn :D
If you want to push some serious clocks I'd suggests looking at the UD3R / UD4 or some of the higher end ASUS'.
