Ill let someone more knowledgeable answer your question, but if I may make a suggestion... set your multiplier to 9 and your FSB to 1333, I think that will yield you better results

I will try and help though. The timings will be looser to get a more stable overclock, try manually setting then to 4-4-4-12 and see if it's stable. Again take that with a grain of salt, but thats what I had to do with my q6600 after I got it to 3.6.

You cant get into the bios? Also set your ram timings, but dont mess with the speed.

The 8800 was a massive difference in games like crysis and did help some in FSX. But Id get a new mobo to overclock that cpu right, then a graphics card. FSX is more CPU dependent anyway, I have mine at 3.6ghz and it maxes all 4 cores.

Overclocking using software will probably hurt you more than it will help you.

There is nothing wrong... look at the 3rd image which displays the memory SPD or on chip memory programming.

The sticks are not designed to function at DDR2 800 (400MHz) at 4-4-4 10, at 400MHz (DDR2 800) they run 5-5-5 15 and therefore the motherboard has selected the correct speed of the modules when the FSB was raised, which raised the memory speed.


If a motherboard has memory voltage settings, and, the memory will handle a bump up in Vdd, then you may be able to lower the timing to 4-4-4, or 4-5-5, etc but without the voltage setting available in the BIOS and without knowing if the sticks can take a voltage boost and not burn up, you are stuck with the SPD rating of the memory.

Also, 1T memory timing is much faster than 2T. If the BIOS will allow it, look for COMMAND RATE or another setting if it is available in the BIOS under the memory settings, (sometimes its a PERFORMANCE / NORMAL  setting) setting COMMAND RATE to 1T, instead of 2T as it is shown in the 2nd image, will boost performance but again, the memory may not be able to run that speed without a voltage boost.


As for 1:1 operation, that usually requires the motherboard allow settings in the BIOS which will keep the memory and CPU in a 1:1 ratio, or, you must understand the math of the motherboard BIOS and calculate what memory frequency matches what FSB to = 1:1


You are running a Q6700 which should have a native 1066 FSB. To run 1:1 you must have the FSB and memory running under this calculation:

FSB/4 x 2 = memory speed (1:1 ratio) so in the case of a 1066 FSB CPU you get the most out of it by purchasing the memory that runs 2/CPU native FSB and manually setting the BIOS so the CPU is LOCKED at 1066 (STRAPED) and the memory will deliver a true 533Mhz (DDR2 1066)

you can also clock a Q6700 to 1333 by setting FSB to 333MHz, it really 333.25, (333.25 x4 = 1333 / 2 = memory for 1:1 or 666.5Mhz memory speed DDR2 1333) otherwise you must downclock the processor and start with a lower number which will work with your memory and maitain the formula FSB/4 x 2 = memory speed (1:1 ratio)


your memory is only rated for DDR2 800 Max and the motherboard may not be able to run a memory upgrade purchase of 533MHz (DDR2 1066). I would have to look at the specs to see if it would.

In order to run 1:1 you must be able to set 2 items in the BIOS at minimum, 3 preferably and a 4th is very usefull for full control which is where the QX or X series processor comes in...

1. CPU FSB (this is the motherboard setting, not the processor ability in FSB)
2. Memory SPEED (settings which allow different memory speeds be locked)
3. Memory RATIO and/or CPU STRAP (setting which allow a ratio divider between memory and CPU and allow locking the internal CPU FSB)
4. CPU Multiplier

All 4 are the best to have but you can do it with 1 and 2... and you can also do it with just one but its a real PITA to do it that way.

If your BIOS does not have a MEMORY SPEED or MEMORY RATIO setting, then you are at the mercy of figuring out what the motherboard does with different FSB settings. As you change FSB the motherboard BIOS has been auto-programmed to change the memory to a certain ratio. You have to use trial and error with different FSB settings, booting Windows and looking at CPUz to find the right FSB which will auto-set the CPU and memory to 1:1

If you have the BIOS setting available which allows you to lock the ratio, its easy to find 1:1 because you do the math yourself

Here is how the formula breaks down:

FSB/4 x 2

FSB = the processors FSB rating or the target FSB
/4 = the setting in the BIOS to get that target FSB ... for a 1066 procesor, you set the BIOS to 1066/4 or 266.5MHz FSB in the BIOS
x 2 = the speed you want the memory to run in order to hit a 1:1 ratio

Lets assume you can lock the memory at a desired speed of DDR2 800 (400MHz) in the BIOS

For DDR2 800 (400MHz memory speed) you need to calculate the FSB/4 x 2 = 400 (the memory speed you can run)

So, reverse the formula. The FSB on the processor for DDR2 800 (400MHz real memory speed) would need to be 800 (800/4 x 2 = 400) so you set the FSB to 200

hmmmm  that means you have to underclock the processor unless you can RAISE THE MULTIPLER to compensate. @ 200x15 that would be 3GHz and you would be running 1:1 with the memory which is set to 400Mhz. You could also set the multipler to 14 and that would give you a proc speed of 200x14 or 2.8Gig, a mild CPU overclock. Since the processor is rated for 2.66GHz, you dont want to run it under that. Slightly higher wont hurt anything.

Now, in the case where you do not have a multiplier to work with, it get tougher. In that case you must be able to install memory than can run the needed speed in he formula and the motherboard must be able to recognize it. So to run the native 1066 FSB of your Q6700 processor at 1:1 (no overclocking) you must do the math...   1066 / 4 x 2 = 533MHz memory product or DDR2 1066 memory sticks, and the BIOS must allow you to be able to lock at those numbers because no motherboard does that for you automatically.

As for recommendations... I am strongly against buying anything that is outdated or will not allow you to run what is coming in processors, memory and video cards. To do so means you are stuck with older technology and must replace everything again to upgrade later.

My recommendation for a better quality upgrade would be an x38 chipset motherboard, or wait a month or so for the x45. You can go with a P35 chipset and still have some room for upgrading but it will be limited compared to the x45 or even the x38. In any case you must make sure the motherboard provides a 8 pin power plug for the CPU, and, your PSU @ 500watts is really not enough. that needs to come up at least 150watts+, possibly more depending on the video card.

They make DDR2 and DDR3 versions of the newer motherboards. DDR3 memory is still expensive however DDR2 is restricted to DDR2 1200, where DDR3 starts at 1333 and goes up. Buying a DDR2 motherboard will mean some restriction in the future but they are less expensive to put memory in than DDR3 right now, much less. DDR2 will still hold its own for another year or so but will quickly become obsolete after next year, possibly around the end.


So for you Q6700 which will do 1333FSB (333MHz FSB) and will work on a DDR3 motherboard running the memory at 666.5MHz (or DDR3 1333) and that is (1:1) you can either go that route, or stay with a DDR2 solution and use DDR2 1066 (533HMz) memory product. In either case, you must set the BIOS up manually to run those numbers.

Happy holidays to you as well.

When you are ready let me know and I will see whats cooking on the market

200 for a motherboard is not outrageous or unusual. As a matter of fact, thats cheap for a decent design. Expect to spend at least 250 on a motherboard. You do get what you pay for in the higher priced boards because they come with better cooling solutions for the chipsets and also include upgraded circuits and BIOS abilities.

Hello,

Newbie here. I found this thread via google. Was wondering if you can help. I too have a DG33TL but with a E6320 running Vista Home Premium. I can't get SetFSB to set the new FSB. It can Get it ok just cant set.

Any Idea's?

Thanks
