Need some advice on my current i5 setup. Basically, I put everything together and left the bios well alone as I just wanted a working PC. Everything is on auto, and the current ram is running well below the advertised spec (1066mhz instead of 1600mhz)

Here's a cpu-z snip;

The temperatures on idle (speedstep on, so 1.2ghz at 0.8 volts) is on low 30's where it used to be low 20s. Obviously, it's now summer, and dust has collected, so I'm hardly surprised. But the voltage on load (as shown) is 1.2 volts for stock (well, turboboost is on, but pretty much stock as no settings have been altered). On stock under stress it reaches 60c pretty quick, and touches 70 after a while. I'd expect that from a 4GHz overclock, not really for stock. :P It's the Intel heatsink, cable management is poor and it's probably quite dusty. But these temps still seem a bit high so would reducing voltage bring them down?

Should I lower this? What's the risk behind lower core voltage? And if it bluescreens during testing, could this mean damaged hardware?

I have overclocking experience on my old E5200, but I've not touched it since. So I'm a bit out of touch. :P

Thanks.

Just lower the vcore 1 notch at a time and test it in Prime to make sure its stable, when it no longer is, put it back up a notch :). I run my 750 at 3.6ghz using the stock volts (1.265 or something like that).

As for your memory check your BIOS for something called XMP - extreme memory profile ( i think is its full name!) and enable that. That should run your RAM at its rated speed. Or alternatly change the memory multipler yourself.
 
yea just go into bios and enable xmp to get your ram up to full speed. tbh i dont see much wrong with your temps, i'm currently sitting at 33/29/33/27 all @ stock. on stress it does go up to about 60 but not really any higher, tho i'm using a cheapish after market cooler (dont trust push pin stock heatsink)
 
Cheers guys. I'll take a look for XMP tomorrow.

I'm looking at getting a new heatsink, have been for a while, is the push pin that bad? I'm not keen on taking the motherboard out, as the last time I did and put it all back it refused to start up, lol (this was with an older build).

I'll try lowering by a notch. I see people running around 3GHz on lower volts than me and feel like somethings wrong, I'm under the impression auto isn't exactly efficient?

Thanks for the help. :)
 
don't know how bad push pins are in reality, but read a few horror stories about them popping out and heatsinks hanging by only one or 2 pins, didnt like the sound of that at all, so bought the coolermaster hyper 212. can't complain about it at all, picked it up for about 20 notes and i've had my i5 @ 3.4ghz and under stress still sits at about 60c (on stock volts btw)
 
About to try it, this is a really random stupid question, but does the CM-690 have any way of accessing the back of the mobo without removing the actual mobo? It doesn't look like it at first but is there something I've missed? :P Cheers.
