I have a overclocked e6850 & the chd's overall run very good but gauntlet legends still needs a computer with about 15% more legs than mine has...maybe one of the newer cpus would work

Got my e8400 on the way, I'll be loading gauntlet first. I'll let you know in a week when its all up and running.

I've been looking at the Quad core for experimental purposes, see what's possible there, even if it's not in the same league it'd be interesting to see how the architecture works at least.

I had quick go with a stock quad core a few months back, but the result didn't impress me and I haven't had another go since, I may try again with the new Q9000 series once they're readly available, there is a Q9300 engineer sample kicking around work but I've done my impulse buying for the month.
I'd really love to see some MAME benchmark results for Q9000 series quad core at 4ghz (yes people have them running that high).

Get to it man, It took me like 10 mins to get 4.0ghz on my E8500, as long as your system is up to it and you've got a good cooler go for, just turn off anything that may get in the way of overclocking, bump the chipset voltages to allow for higher FSB and hit the CPU with 1.4v and crank up the FSB to 445mhz, make any memory setting changes needed to keep your memory speed in check, and you should have yourself a 4ghz Core 2 Duo, that's about all I did. There's a little more to it than that, just ask if you want more details.

I'm not going to tell you to dump your E6850 and get a E8400, I think that Z-cooler is still holding your E6850 back some. But the E8400 does look to be an easy 4.0ghz and you can probably keep your current setup including your heatsink, I my new CPU up to 43-46 deg C at 100% load at 4ghz. Every thing after 4.2ghz was hard work, but I think that more down to cooling and luck.

Good luck with it, they are a great CPUs, just watch out for those crazy core tempature values, stick to the lastest version of CoreTemp and don't be suprised if one of the Core temps is stuck in the 40s.

Thanks for the awesome thread and all the hard work. I expect to push it to around 3.6 from what I read, and because of the fact I ordered ddr2 800 it may be a bit difficult to overclock to around 4ghz on fsb and voltage/timing ocing alone, I will probably be back for more advice (in another thread) on the ocing of the board and any advice you may have. Thanks again and I'll be lurking this for a while ;D

Thanks,

The fact that your getting DDR2-800 doesn't mean you can't overclock to 4ghz, It just mean it's more complex and thus more differcult to do. To get a E8400 with it's 9x multiply to 4ghz you need to be running a 445mhz FSB (445*9=4005mhz), since the mininum memory ratio you can run on a P35 chipset board is 1:1 (2.0 in bios) your memory will end up running a DDR2-890 mininum, so you'll need to overclock your ram too, bumping your Memory voltage up a bit say to 2.0v will probably be all you need, but if voltage alone doesn't work for your ram then you can loosen the memory timing some, say it stock 4-4-4-12 then you might try 5-5-5-15 instead, A little bit of testing and tweaking should get you there.

Don't try and overclock everything at once, it's too hard to workout what's causing a problem.

Start with the ram just increase the Memory Multiplier from the stock 2.4 to say 2.66 with everything else stock and test the PC, with the stock 333mhz FSB this will give you a RAM speed of DDR2-886 (333*2.6=886), this is close enough to your required RAM speed of DDR2-890 to test the system for stability with the only the RAM overclocked.

Once you happy you got the Memory timing and voltage right you can move onto the FSB, drop the CPU multiplier to 6x, and the Memory Multiply to 2.0, then pump up the FSB to 445mhz and increase the chipset & FSB voltages as need to stablize the system, The CPU will be underclocked at this point at only 2.67ghz (445*6=2670mhz) and you've already set the memory timings to work at this speed, so your only dealing with the chipset stability.

Once you happy with the system with the FSB and RAM overclocked, increase the CPU Multiplier one step at a time from 6x until you get to 9x, test the system for stability at each Multiplier step, and increase the CPU voltage as need to get the system stable before moving on to the next Mutliplier, Until you get the CPU Multiplier to 9x, you should now be running a 445mhz FSB with the CPU multiplier at 9x and you Memory Multiplier at 2.0, giving you a 4.0ghz CPU with a 1780fsb and DDR2-890 ram.

If done right and with a little luck it will be nice and stable at these settings, now you need to torture test your CPU with something like Orthos, to take it to 100% load and hold it there for hours, I suggest at least 10 hours for you final test with the PC house as it will be in operation. Keep an eye on the CPU tempature and make sure it stays within safe limits anything up to 65 degs C is ok, over that is getting hot, and if it gets to 80 Deg C it will more than likely lockup before it can do any real harm, you really want it in the 20-30s at idle and in the 40s to low 50s at full noise. If it pass that it should be ready to use, it you want to further test it warm up the room tempature to that of a hot summers day and test it again for 24 hours, if it pass that you good to go.

Then all your've got to do is have fun.

Make sure your BIOS and Drivers are up to date before you start, I suggest using CPUz to get Live actual CPU speed & voltage information, the lastest CoreTemp is you best bet for watching CPU core temps, Orthos does a great job of stress you CPU & RAM to in limits (use blend test) and Windows task manager will confirm your CPU is at 100% load on all cores.

Just take your time, and test each new setup with orthos as you go.
