Hi.

I've tried my hand at overclocking my new system:
Intel Q9300
Asus P5N-D
4Gb PC-6400
2x 8800GTS 512

I've had moderate success. Starting to accept that it's unlikely I'll ever see it tick over 3.4GHz.
It seems pretty stable at CPU 3.25GHz, FSB 1733 (433x4), and Memory unlinked at 866MHz.

I really need to shave off some heat as I think you'll agree that the following temps are a bit excessive:

CPU idle: 41.C load: 60.C
Motherboard (I assume this refers to the NB) idle: 48.C load: 57+.C

Core voltage: 1.216 (cpuz) actually set to 1.26 in the bios.
Memory voltage: 1.85 (bios auto)
HT: 1.40
NB: 1.36
SB: auto (unknown)


In which order do I need to start reducing the voltages in order to get rid of excess heat? reducing the vCore voltage seems to give me mixed results, sometimes it'll POST, sometimes it will hang.

Has anyone out there got a similar setup to me, and perhaps had better luck? care to share? :p


Thanks,
Jordan

what program are you using to monitor your temps? Try realtemp if you aren't using that already, I've heard it more accurately reports temps of chips with 45nm tech. I was having similar temp reporting problems when overclocking my Q9300, and after doing a little research switched to realtemp. My idle temps are between 40-45 and my load temps are between 50-55. This is down from ~50 idle and ~60 load in HWMonitor and speedfan.

I was using Speedfan and Asus AIGear. I'll try realtemp tonight after work. My main concern was the northbridge chip. I've installed the optional NB fan that comes with these motherboards, and it hasnt made a huge amount of difference. NB Idle at just below 50.C is excessive isnt it? or Am I making a fuss about nothing?

Anyone care to critique my voltages?

I don't think changing programs is going to help you any on your 'motherboard' temp. I don't know if that's NB or not (I'm pretty new to this as well ;) ). But it will give more accurate reading of your Core temps. As far as NB I've got one of my temp gauges on my case taped to the NB heatsink, and I've never seen my NB go over 35C.
