Hey,
As the title suggests i have a Biostar TP45 MB and im trying to overclock my G6600 CPU. But for some reason it fails every time. Im trying to get it up to 3.2Ghz. I have tried changing just the FSB to 300/333 and disabling the speedstep but no luck. Does anyone have any experience overclocking with the TP45? What settings do I need to change for it to work?

Next of all, if you have just bought you motherboard, I would recommend exchanging it for something a little more overclockable.

Also, it helps if you post your entire system. CPU/Ram/Motherboard/Cooling as these things will affect your overclock. Include which Stepping your CPU is as well, as this limits how fast your overclock COULD be.

Just to note, i cannot get my memory to produce at 1066 as you can see. I've tried many things but with no luck(Settings in BIOS and volatages). It keeps coming out as PC2-6400.

It shows as PC6400 because that's how the SPD is programed...many manufacturers do this to insure it will boot at 1.8 volts since that is the deafult for many boards.

you can change it in the BIOS to run at PC8500 like its rated for by changing the voltage to 2.1 and memory speed to 533 but CPUz will always identify it as PC6400

Did I explain that right....?:-/


Im using the same memory and it shows at PC6400 also..but mine is happily running at 540Mhz...
 
• The number after it is the data transfer rate. Simply divide it by 2 to get the maximum FSB speed for which the module is rated. Example: 800/2 = 400 MHz. Therefore, DDR2-800 can work on systems with a FSB of up to 400 MHz (anything more and you’re lucky).

^^^ This is in the sticky I posted. Your Memory is running at a stock 1.8V it will run as PC6400 until you up the voltage. Probably ~2.1V Then it will run at 1066 speed, but still identify as PC6400 as crosshairs stated.

Keep in mind that according to the above statement, the Ram FSB (you set in bios) is half of the rated FSB.

So currently you are running at 333 FSB. 333X2 is 666 (667).

This means that at stock Voltage you are underclocking your ram.

You can turn it up to 400 and it would run at 800.

If you turned up your voltages to 2.1 You could run your ram at 533, which would give you 1066.

However there are a few things to keep in mind.

As you raise your CPU fsb, you will marginally raise your ram FSB unless they are not locked together, which they usually are especially on budget boards.

So underclocking your ram is actually beneficial while your overclocking your CPU.

If you start your ram out at 667, and put your CPU at 333X9 it will give you 2997Ghz.

If you raise it to 340X9 it will be 3060 Ghz and your ram will go up to 340 = 680, and so on.

Once you see where your final CPU FSB is at you can adjust your ram accordingly.

Example: My CPU I can set it at 450X8 or 400X9 to achieve 3600 Ghz.

This means my ram can either bet set at 801/2 = 400 FSB (For X9 multi) or 901/2 = 450 for (X8 multi).

@400 FSB I can run my ram at about 1.9V and at 450 around 2.0V.

If I wanted to I could also run my CPU @ 514X7 = 3598 Ghz which would be 1028/2=514 but I have a dilema.

4GB of my ram is rated @PC8500 (1066) and 4GB of my ram is rated @PC5300 (667) "my old ram".

Now I could just run the new ram with only 4GB and be happy. My CPU can actually go up to 3.7 with only the 4GB, but....

I don't like the waste of ram. So I have to find a balance. In dual Channel my PC5300 can run 800 FSB and I can push it to 900 FSB.

Soooo, I can either run my CPU @400X8 or 450X9 for 3600. Keep in mind, running your FSB higher will affect everything in your system.

Running a higher FSB will run a scoch faster, but only something you might see on a benchmark, for real world applications, I would go

to the lower to save heat and wear and tear.

Capice? I hope I explained it well and don't get flamed from the real overclockers.

Yea ive uped the voltage on my ram and overclocked the cpu to 3.2. It didnt work because i had the fsb set to auto not 1333.
 
You mean 333?

It looks like your CPUZ post showed your ram Freq. @400. If your CPU was locked to your Ram FSB, then that means as you increased it by 1 your ram would go up 1X(2). So As you went up your CPU FSB would be at 270 an increase of 4 FSB, your Ram would be at (400+4)X2 = 808. When your CPU FSB is at 280 you had another increase of 10 FSB. (404+10)X2= 828 FSB. And so on.... By the time your CPU would make it to your target of 3.2, your FSB would have to be 355. Sooo... from 266 to 355 would be 89 FSB difference. (400+89)X2= 979 FSB for your ram. That clock would be too fast and you would BSOD. Lets say you had really good ram, you could run 900 FSB. That would be an increase by 50 FSB instead of 89. So your ram would get you to 316 FSB. 316X9 would be 2844Ghz. Does that sound like where you were crapping out? It would have been higher if you set your voltages @ 2.1, that would give you a cap of 1066 instead of 800.
