Wrong timings and FSB:DRAM ratios

[SubZer0]

Hello folks. I just got a Q6700 with the DG33TL motherboard.

I raised the FSB timings from 266 to 300 in order to get 3.0GHz out of the processor.

I checked on it with CPUZ and these are the results:

BY RAISING THE FSB ALONE, I WAS ABLE TO GET IT STABLE AT 3.0GHz AS SHOWN HERE






HERE IS THE PROBLEM (I THINK).
1) MY RAM'S CAS LAT IS SUPPOSED TO BE 4 WITH A TIMING OF 4-4-4-12
2) ISN'T THE RATIO SUPPOSED TO BE 1:1?
3) EVEN WITH THE FSB SPEEDS AT STOCK, THE MEMORY SHOWS THE SAME RESULTS.
ISN'T THIS STRANGE? HOW CAN I FIX THIS AND WHAT IS GOING ON HERE?
I'M NOT A PRO AT OVERCLOCKING, SO I REALLY NEED YOUR HELP.





I HAVE THESE TWO OTHER PICS TO SHOW MORE INFORMATION IF NEEDED.







PLEASE HELP IF YOU KNOW WHAT IS GOING ON HERE AND TRY TO EXPLAIN TO ME WHAT IT IS THAT'S GOING ON WITH THE HARDWARE SO I CAN LEARN MORE AND GET SOME MUCH NEEDED EXPERIENCE. THANK YOU ALL IN ADVANCE FOR ANY HELP RECEIVED.

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.

Before you suggested it, I manually set my timings to 4-4-4-12 and the speed to 800MHz, but the computer wouldn't even boot up, so I had to reset CMOS or w/e it is and keep it at auto or 5-5-5-12 in order for it to work.

About setting the mutiplier.... I can't. I used the program called SetFSB to set the FSB only, and it automatically made my multiplier go to 10. All that program lets me do is the FSB, nothing else. Do you know of any program that will allow me to set the multiplier? The thing is that I have an INTEL motherboard (Intel DG33TL) and it doesn't let me change anything for the processor.

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

[SubZer0]

I can get into the BIOS, it just doesn't allow me to change any CPU speeds, so I have to overclock using software, which I don't like.

I need a new motherboard, but I really can't afford one. Do you think I should upgrade from a 7950GT to an 8800GT superclocked? Is it worth the money? How much of a difference will it make?

[ThatOnePerson]

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.

[SubZer0]

I"ve just decided to go with the 8800GT superclocked by BFG Tech. That's US$320.

Which mobo should I get? I don't want to spend more than US$150-200 on it.

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

Wow, that sounds complicated. But I do very much appreciate your time explaining.

I understand a little, you lost me at the FSB calculation part for a sec.

Nick, I'm obviously going to have to upgrade the motherboard (I hate this one anyways - DG33TL) and get some better RAM in order to run well with the Q6700. What do you recommend? I have a 500W PSU as of now, will I have to get a better one when I buy a new graphics card, RAM and Mobo? Also, which Motherboard and RAM do you recommend me to run with the Q6700 to get the best cooperation possible with no overclocking?

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

Nick, I understand what you just explained. Once again, thank you.

I was just looking at the x38 motherboards and they're over $200, money which I don't have as of now, and will not for the next few months - I have to upgrade the video card, motherboard, RAM, and PSU. Which will be approximately US$800. So that will definately take a few months of saving. I wouldn't like to upgrade now as you said, newer things are coming out very soon and my upgrading capabilities will be limited if I upgrade now, so I'll just go ahead and wait for a few months, till march perhaps, and see what I can do at that time.

I've saved that post just to review it in case I forget. Thanks again and happy holidays.

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.

[SubZer0]

Thank you.

According to my calculations, I will be ready at the very end of March with about US$1000, maybe sooner (let's hope tax returns are good lol)

I'll let you know when the time comes.

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
