Recommendation for an experiment.

post #1 of 3
Thread Starter 
A friend and I were testing out overclocking on a custom built rig that I purchased a couple months back. Since he is an experienced overclocker I figured he would be able to help me do it properly but I'd like to get a couple other opinions.

These are the specs on the machine:

Quote:
Intel Core 2 Quad Q6600 Kentsfield 2.4GHz (Stock cooled)
4x Kingston 1GB 240-Pin DDR2 SDRAM DDR2 667
Windows Vista Ultimate x64
ASUS P5N32-E SLI LGA 775 NVIDIA nForce 680i SLI ATX Intel Motherboard
Antec True Power Trio TP3-650 ATX12V 650W Power Supply with Three 12V Rails
The first thing he groaned at was my memory. Said it was garbage. Apparently according to him, my first mistake was getting garbage memory and stock cooling. Oh well....

We continued experiementing and barely made 3.0GHZ (1325 x 9), Prime95 ran for 2 hours fine without errors, however AssCreed (1440x900 max details) froze after an hour or so of playing. So we bumped it down to 2.8.

Whenever we pushed past 1400 FSB (9x), the computer wouldnt boot to POST at all. We figured it was probably voltage and upped it up to 1.45, still no boot. We realized the ASUS mb was doing a decent job of linking the voltages so we left it all on auto. At 1400>1500, we couldn't get to post. At 1500+ we stuck on the Vista loading bar. When we did 8x clock and 10x clocks for experiment, vista would BSOD after password screen so we abandoned it. After 5 hours of playing around we left it at 2.9 (1325 x 9, auto voltage and 667 unlinked memory speed. )

So finally here are my questions

1. I ordered the Corsair Nautilus500 water cooling kit and it came in today. I installed it and it dropped my full load temps from 47C to 32C (WoW).

2. I ordered G.SKILL 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 1000 (PC2 8000) Dual Channel Kit Desktop Memory. (yet to come)

Making the final specs:

Intel Core 2 Quad Q6600 Kentsfield 2.4GHz (Corsair Nautilus500 Cooled)
2x G.SKILL 4GB (2 x 2GB) DDR2 1000 Dual Channel Kit
Windows Vista Ultimate x64
ASUS P5N32-E SLI LGA 775 NVIDIA nForce 680i SLI ATX Intel Motherboard
Antec True Power Trio TP3-650 ATX12V 650W Power Supply with Three 12V Rails
What kind of stable overclocks can I expect to get. I'm not greedy, so I don't want to push past 3.7. But I was thinking 3.6 might be a sweet spot. Can I pull that off? What recommendation or opinions might you have on how to go about achieving 3.6? manipulating the FSB more or move over to the clock?

Appreciate and welcome all comments and suggestions.

Which Q6600 stepping do you have B3 or G0?

I doubt you will be able to hit 3.6GHz since the chip is having issues at 3GHz already. I think you might be able to hit 3.2GHz but not much futher.

According to CPU-Z, it says Stepping: B (no 3) but my Revision says G0. From my research already, I see that G0's "overclock better and runs cooler". So I'm gonna guess that thats why I'm having issues if its B3 I'm on.

Would the memory and water cooling allow me to go higher at 3.2 [emphasis]at all??[/emphasis]

Here are some other notes we made:

1. We did technically hit 3.2 and it ran stable for an hour. But that was having the motherboard's AI autoclock the memory to about 832GHZ (keep in mind, they are 667 sticks) When it did hang after the hour, we figured it was the memory.

1066 + Auto [667] = Default
1350x9 + Auto [832] = 1 Hr* Stab
1350x9 + Unlinked [667] = 4+* Hr Stab (Crash in AssCreed)
1350x9 + Sync Mode [772] = No Boot
1350x9 + 3:2 [712] = No Boot
1375x9 + Unlinked [667] = 4+* Hr Stab (Crash in AssCreed)
*Per Prime95 Tests

When we upped it to 1375x9 Unlinked [667], it rebooted fine, OS loaded fine, and AssCreed went on for 2+ hours before the crash. So the chip is allowing us to push for higher, but since the memory has no heat spreaders and are relatively old, we figure that was the core issue behind us not getting the stability we want.

You can tell from the tests we did that we kept the FSB the same, but when tinkering with memory speed, its whats giving us the different results. What do you think?
