Core 2 Quad Q6600 G0 Stepping

post #1 of 11
Thread Starter 
So I migrated to the dark side some time ago, and really haven't been overclocking, I've managed to be content with having roughly six times the processing power I once did. That said, 2.4GHz is not enough. When I bought the chip, it was my understanding 3.0GHz out of a G0 revision core was a pretty good bet. Looking around here it seems such implications are true, and promises of clocks greater than 3GHz seem achievable. I do have some basic questions as I've been out of the scene for some time, so I need some re-educating... First off, the bugger runs hot! According to Hardware Monitor at least, I'm seeing idle temperatures of 40C for the CPU (I'm assuming this is the socket-mounted thermal diode), and about 50C on each of the four cores, and it rises up to 50C/60C under load for both respectively, running a Thermalright MST-9775LE cooler at the moment. It's not much better than stock... but... well, I have no idea why I bought it to be frank. Looking at upgrading to he HR-120 Ultra soon though. Also what's a good voltage ceiling on this thing? And then you guys are going to have to enlighten me on the premises of this whole external memory controller thing again. Is it or is it not better to keep the 1:1 ratios? I don't see my FSB doing 2000MHz, alas, right now I've it running a 4:5 divider with a 400MHz FSB and the RAM at 500MHz. Looking to get the most out of this thing I can within reason (reason being the upper limit of air cooled) as I don't intend to buy another processor until octo-core or 16-core chips become available.

What is your VID?

I've actually dropped it down to 1.10v (though it's showing up as around 1.15v in all the monitoring apps), but it didn't really seem to cool it off any.

You can't control your VID, use cpuz to check it. It's basically the amount of voltage it needs to run its original speed(2.4GHz). The lower the VID the better, since it means you can overclock without raising voltages as much as others who have a higher VID.

I use CoreTemp to check the VID. If you have 1.3 or higher, you don't have a great chip.

If it's 1.25 or lower... You're lucky. With a TRUE a 1.2VID would hit 4Ghz under benches.

Oh, default core voltage? Hell if I remember... Too lazy to jump back into BIOS to set everything back to default too... the box lists a maximum voltage of 1.375v though.
Checking that CoreTemp software, seems I got a dud, VID of 1.325v. Oh well...

Pop the FSB to 333 with a voltage of about 1.35. If that doesn't work slowly up the voltage.

Even though your VID is utter crap (sorry, 1.3 sucks lol) you should be able to attain 3ghz on stock voltage.

I have a 1.325 VID and my chip is not a dud. I'm at 3.6 ghz with 1.440-1.456 vcore. I don't consider that a very bad chip bro.

If all you are trying to acheive is 3.0 ghz then you dont need to mess with the stock voltage. I would return it to stock (1.31 for me i think) and go from there. For me 3.0 is VERY stable. I run my RAM at 1:1 but thats at 667mhz and i know it could go faster but it just seems more stable for me at least. Q6600 can easily get to 2.4/2.6 and still keep a decent temperature. Its a beast of a chip. Its super easy to surpass the core2 extreme quads and stock performance for a fraction of the cost.

Yep, thats your VID. They can still overclock well enough, though lower VIDs Typically can go farther.

As to the FSB: DRAM (1:1) question, the info from the FSB will get to the ram when it will. Higher FSB is good obviously. Having higher ram speed though means the ram runs faster. Run the ram as fast as you can, with stability. The same rule applies to the older OCing rules. Make everything run as fast as possible. Ratios dont matter as much anymore.

For a voltage ceiling, people say 1.55v should be the maximum for this chip. Im sure you'll hit the temperature barrier long before your voltage gets that high though, unless you decide to use quite a robust watercooling system. My Q6600 runs 60C at 1.3875vcore, at 3.7ghz. Ive got a decent watercooling system in place, so an air setup probably wont go so far. A good air cooler might hit 3.6ghz and be under 72C. 72C is the absolute highest you should get a G0 chip to, as intel specifies that thermal limit.
