Hi, i have the following set up:

E6600
2GB Geil Ultra PC2-6400
P5W-DH Deluxe

I have the E6600 running at 3GHz and a FSB:RAM ratio of 1:1. My bus speed is rated at 333.5 (cpu_z reading) and my multiplier is x9; CPU is running at an effective FSB of 1334. I have the CPU_voltage set to 1.375 in BIOS, though this is actually running at 1.336 according to cpu_z. Memory voltage is 2.3V with timings of 5.6.6.18

I have this set up as i was informed the 1:1 ratio means there is no delay caused by one component waiting for the other. The problem i am having is even with the Artic Cooler Freezer Pro 7, my CPU idles at 50 degrees (TAT readings). I am also concerned at the poor timings for my RAM, which is only being rated as 5300 due to the low FSB.

Anyone got any ideas as to whether i should up the RAM FSB, and lower CPU voltage? Or anything that may lower the temp of my CPU without affecting performance? Or do you think the heat sink is just not seated happily, as everyone else i have seen with a freezer pro 7 is posting temps a lot cooler than this.

(Other info: Case is an Antec Titan, 2x92mm intakes at front and a 120mm exhaust at back)

Thanks in advance :)
 
Comparing temps is difficult in that everyone has different factors in play. Airflow & ambient temps are just two things to consider aswell as you might be unlucky and have a concave IHS which only a good lap job will solve. The arctic cooler 7 is pretty much n00bproof not to get a good mount aslong as all the tabs are 'clicked' into position so I doubt its the mount. Your only option to get better temps really is to try lowering vcore but this could make your overclock unstable. Other than that to see if its airflow thats the problem take of the side of your pc case and see if that makes a difference to your cpu temp, if it does this means that your AC7 isn't getting fed enough cool air.

To get your memory running at spec and to run 1:1 would be to lower your cpu multi to 8 and up your FSB to 400 which would give you an overclock of 3.2ghz (which would likely increase your cpu temps further) but would get your memory running at 400(800)mhz - 6400. Your memory timings are also slack as they should be 4-4-4-12.
 
Thanks for the suggestions. I'm happy with the performance, even though my memory is a little lapse, getting a comfortable 58.5fps on a UT2k4 benchmark @ 1600x1200, its just the temps.

I think i'll be trying a lap on the next rainy weekend to see how it goes after.

I've seen about 10 different guides for lapping and all suggest different things. As i dont have any of the equipment at the moment, would you suggest one of the chemical based complete solutions or the sandpaper route? Also, pointing me in the direction of a "good" guide would be apprecaited.

Cheers.
