Q6600 overclock settings correct?

[TTTT_99]

sup dudes i just wanna know what settings i shoulld have on my ram when my q6600 is overclocked to 3,4 Ghz (377 * 9) i have a really good and expensive cooler , temps are now on idle at 30 degrees. My specs:

CPU typ QuadCore Intel Core 2 Quad Q6600, 3400 MHz (9 x 378)
Motherboard: Asus P5W64 WS Pro (2 PCI, 4 PCI-E x16, 4 DDR2 DIMM, Audio, Dual Gigabit LAN, IEEE-1394)
motherboardchipset: Intel Glenwood-DG i975X
systemmemory: 4096 MB (DDR2 SDRAM)

My ram:
DIMM1: Corsair XMS2 CM2X1024-6400 1 GB DDR2-800 DDR2 SDRAM (5-5-5-18 @ 400 MHz) (4-4-4-13 @ 270 MHz)
DIMM2: Corsair Value Select VS1GB667D2 1 GB DDR2-667 DDR2 SDRAM (5-5-5-15 @ 333 MHz) (4-4-4-12 @ 266 MHz) (3-3-3-9 @ 200 MHz)
DIMM3: Corsair XMS2 CM2X1024-6400 1 GB DDR2-800 DDR2 SDRAM (5-5-5-18 @ 400 MHz) (4-4-4-13 @ 270 MHz)
DIMM4: Corsair Value Select VS1GB667D2 1 GB DDR2-667 DDR2 SDRAM (5-5-5-15 @ 333 MHz) (4-4-4-12 @ 266 MHz) (3-3-3-9 @ 200 MHz)

gfx:
NVIDIA GeForce GTX 260 (896 MB)

Right now the only thing i have done in bios is to overclock the CPU to 3,4 Ghz and its running stable with crysis on highest settings. my DRAM frequency is at 283.8 Mhz and FSB/DRAM is at 4:3. is these setting good or is there anything i need to change? my system is stable for now but just in case i ask you guys

try ti get all ur ram at the same timeing and as far as i know 4-4-4-12 is the best

You have 2 pairs of mismatched RAM. Unless you get really lucky, the best you can do is get the RAM running at the slower speed.

Also consider using a real stress testing tool like Prime95. I'm not sure if Crysis puts a full 100% constant strain on the CPU.

shoulld i switch places of my rams? i mean put the 2 XMS rams intill eachothers and the 2 value select intill eachothers?

It will not make any difference which slots you put them in. (Where they are is good.) They are still going to be mismatched. You will still be able to overclock - maybe not as well - and you will need to spend extra time working with your memory.

If you have your FSB:RAM ratio running at 1:1, at a 378 MHz FSB, your RAM is running at DDR2-756. So you are doing pretty good with one set of DDR2-667 RAM.

I would try to set your FSB:RAM ratio to 1:1 if it isn't. Manually set your RAM timing to 5-5-5-15 and increase your RAM voltage to no more than 2.2 volts and see what happen.

3.4 GHz is a respectable overclock for a Q6600.
