OC time. Computer.. not the show.

Decided its time to work on my Overclock settings on the PC a little more.
I'd upgraded the BIOS about a week ago and hadn't re-set the overclocking settings I'd saved previously.

For those who haven't seen/heard of the black box of doom I run.
DFI Lanparty P35 board.
Intel Q6600 Quad core CPU (defaults to 2.6ghz)
Corsair 2GB DDR2 800 TWIN2X2048-6400C3DF Kit(3-4-3-9)
Graphics card is an ATI Radeon HD 2900 XT (I like ati..what can I say..)
and 3tb of hard drive space (2 x 1tb and 2 x 500gb - no raid at the moment)
OS: Windows XP Pro SP2 + Ultramon (always running)

So, running up Everest (by Lavasoft) to do some benchmarking/inspections for me, I've started speeding up cpu and lowering memory timings.

Note: Results are the CPU benchmarking tests
CPU Queen
CPU PhotoWorxx
CPU Zlib (kb/s)
CPU AES
FPU Julia
FPU Mandel
FPU SinJulia

Tests Round 1:
CPU Overclocked to 3ghz, ram on auto.

22231, 29247, 81491kb/s, 23061, 23346, 11238, 17264

Tests Round 2:
CPU Overclocked to 3.0ghz ram settings 4-5-4-12 (turned voltage up to 1.95v for ram)

22295, 29773, 81567, 23092, 23337, 11256, 17210

Test Round 3:
CPU Overclocked to 3.1ghz ram remains the same.

23002, 29984, 84103, 23879, 24077, 11617, 17812

Test Round 4:
CPU Overclocked to 3.1ghz ram settings 4-5-4-10

Stopped here to boot up my ubuntu live cd and do a memtest as well, ensuring that the memory wasn't error-ing and likely to cause issues later on. (I'd recommend doing this before you start your overclocking also) Memtest reports a transfer rate of 3786MB/s on the RAM and no errors.

Test Round 5:
Made some major changes after reading the following - http://forums.techpowerup.com/showthread.php?p=655674
Settled on DRAM Speed of 333/800 - as it crashed on the suggested speed.
So changed CPU back to 3.2ghz and ram back to 5-5-5-15

24136, 31482, 88292, 25072, 25275, 12196, 18649

Test Round 7:
Another memtest to check how it's holding up. Everest benchmarks are sitting at a couple of top places on the Everest example charts. Memtest reports 4101MB/s RAM Transfer Speed

Everest Test gives results
24758, 32376, 90437kb/s, 25720, 25882, 12496, 19159

More tweaks tomorrow night.
Biggest issue can see at the moment is that the northbridge chip is heating up considerably after increasing the voltage, will try to reduce that without losing stability, or fit it with a full heatsink+fan

And for a quick stability test - OCCT
