Need help with OC

[Malk]

I just got myself a Q6600 stepping G0 and 2x1 Gb Cellshock PC6400 CL4.

When trying to overclock them i was only able to reach 360x9 FSB with the memory at 450 MHZ 5-5-5-12.
Then i tried to lower the FSB so i could test the RAM at 400 Mhz at 4-4-4-10, no problems there.

I then raised the FSB to 400x9 and RAM at 1:1 4-4-4-12 at 2.10 Vdimm, now it wouldnt Post.
I tried to boot with the same settings except i let the BIOS set the timings pr SPD, it booted but the timings was set to something like 6-8-8-16, at 400 MHz??

Do i need to raise the SB/NB above the minimum non-auto settings?
And lastly how much current can i give the RAM and the SB/NB when i dont have any aftermarket cooling?

I have a Antec 900 with 2x120 mm in the front, 1 120 mm in the side window, a 200 mm on the top and a 120 mm in the back sucking air out, so the air is being replaced pretty quickly.

I hope theres someone that can help me with this, its pretty frustrating to have spent a fortune on the best parts and then only getting a mediocre result.
Especially because the individual parts work fine when testedindividually, but not together

If you need more info or if you need me to explain it better ill try, thank you all in advance.

I don't think your holdup is ram, your probably hitting the wall on the chip. 3.6ghz is a huge O/C for a quad

Your asking for too much of an OC with your components.

1. Your PSU is very lacking for a steady power stream to a quadcore.
2. You NEED and i cant emphasize this any harder, a TUNIQ, Ultra120Extreme, Or Good Water to maintain a stable 3.6ghz+ overclock for long periods of time.

yes you are going to need a quality power supply to get to 3.6GHz and i suggest a TRU120x for your heatsink. I just completed my first build and ive got my q6600 g0 at 3.6Ghz rock solid stable 1.42v. I would suggest at least a 650W power supply. It would probably be better to go a little higher just to give yourself some room to expand. I would also suggest you lap your IHS and heatsink.

Im so sorry, i havent updated my signature in ages, heres my current setup:

Asus P5B Deluxe - Antec Nine Hundred
Q6600 KentsField - 360x9 1.325Vcore
ASUS 8800 GTX - NorthQ Giant Reactor 1000W
2x1024 Cellshock PC6400 CL4 - X-Fi Xtreme Gamer
300 Gb Seagate 7200.7 IDE
2x250 GB Samsung SP2504C RAID 0


And like i wrote im only trying to get the CPU and RAM to work together at 400x8 without the timings being 6-8-8-18.
And since its a G0 revision 400 FSB shouldnt be unobtainable.

Can noone tell me if more voltage to the SB/NB will help with my problem?

And how much can i give it without frying the chipset?
