Need help with overclocking a Q6600 on a
Striker ll formula mobo.
Rev B
Stepping GO.

Well, welcome to our forum! First of all we need to know your BIOS revision: I owned your board for a very short period and bios wasn't able to overclock my Q6600 G0 above 3,60 GHz. Now I think the last bios should do the job, just flash it. You can download it from Asus support site, support.asus.com -> Download Section -> Formula II -> Bios

When you flash the last bios, we'll need to know your temp about CPU cores with CoreTemp or SpeedFan.

Thanks for the welcome. Bios is REV: 2201. Had no success with latest Bios rev.
Would not run my 1066 ram on anything other then 800. As for temps (coretemp) Average of 21C, idle and 39C under 100 percent load (prime95 small).

Well, temps are good. Let's begin with a small OC: can you reach 1333 on FSB with stock vCore and NB Voltage?

No will not post at 1333

Ok, let' increase NB voltage. I remember I had to drop it to 1,45 V in order to post at 1333 MHz. Leave CPU vCore at stock and downgrade CPU multipler in order to be at the same frequence as stock but with higher FSB (1333).

P.S. Which ram are you using?

The Ram I am using is corsair dominator PC2-6400. (CM2X2048-8500C5D)
8gig 4x2gig

ah yeah, 8 gb of ram will make that mobo mad to post. I suggest you to drop out 4 GB and try to overclock with only 4 gb, then you'll put in the other 4 gb. When I used that board, I increased the NB vCore to an high voltage in order to post, increasing VTT and FSB voltage to 1.4.

Could you explain the voltage voices in your BIOS dealing about CPU/FSB/NB/SB/SCHIPSEt and whatever?

Your idea worked. Removing 4gb of ram and dropping the multiplier.Ive then put the ram back in.
This is what I came up, what do you think.
PCIEx16_3: 100
PCIE-1: 100
SSP<->MCP Ref Clock: 200
FSB:1800
Mem: 900
CPU Multiplier: 8
CPU: 1.4v
CPU PLL: 1.56
CPU VTT: Auto
NB:1.44
SB: 1.55
1.2v HT 1.45
Bridge core: Auto
This has seemed to achieve a stable clock at 3.6Ghz.
Temps under idle 35 and under 100 percent load 49c.(Prime95 blend test, 12 Hours)

Ok, you are on the good way. You have to know that NB sucks: to reach a stable FSB of 400 x 4 = 1600 MHz and 8 Gb of ram you'll get into hell!

But let me know that 1800 MHz FSB with 8 gb dual channel is very very good for that mobo, congratulation! Now your only problem could be the CPU: in order to grow the multipler, you should increase VTT voltage, this will cause an overheat. I suppose you have now 8 x multipler (800/4 * 8 = 3600 MHz). Lets try x9, you should reach 4050 MHz on CPU, but this will need hughe overvolt on CPU vCore and VTT.

Just try and let me know, your result is good!

No could not get past post with multipler raised to x9.
Even with huge increases in vcore and vtt voltages.

Ah... what a waste... I think it is mobo fault...
