Need help with 945 overclocking

post #1 of 12
Thread Starter 
I have this CPU. My motherboard is good with overclocking and had a few questions relating to bus/ram/nb all that.

My cpu is locked so the multi can't go above 15. This RAM I have is rated for 1600, but shows up as 1333 in the bios, so I change the multi from auto to 8x and its 1600. Okay done. Then I want to overclock my CPU by changing the bus to 234 which = 3.510 ghz which is just great for me.

The problem is that the ram speed and nb and all that other stuff gets raised too, and I don't want to run my ram faster than what its rated for. I have to clock the ram mutli at x6.66 so it doesnt go over 800 for each stick. it sits at 780, but the bios sees it as 1333. Is this ok and almost the same thing as 1600? Also in my cpuz it shows 3 to 10 for my fbs:dram ratio. What does this mean, really, and is there a slow/faster way to set the cpu clock and ram clock up?

Everything is fine. When you are overclocking using the base clock you have to pretty much always lower the ram multi (unless you have higher spec'd ram) to get it stable. Same goes with the HT link and CPU/NB multi.

HT link is best kept around that 2000 mark but the CPU/NB with that chip around 2600 should be fine.

The ram timings look to be ok


does this mean that the ram is running in jedec 3 all the time since thats what my settings are most close to?

Drop the HT link down to 9x multi and your cpu/nb where it is. That is pretty much all I would do. Your ram is running pretty much at it's stock settings already.

Just did this. Ht is 2106 and nb is same at 2340. This is okay?

Also, what are fsb:dram ratios mean and what does it have to do with anything?

Yep that is fine Don't worry about the ratio it means nothing. It's not like the core2 days when 1:1 was what you wanted.

That's the same CPU I got at the beginning of the month. I have it going at 3705mhz using 247 fsb with HT at 1976mhz and ram at 1646mhz (823mhz x 2) and the NB at 2470mhz. For optimal performance you want to get your NB at 3x your RAM so in your case it would be 2340mhz which is what you have it at so that's good.

For HT you want to be as close to 2000mhz as possible. Some say overclocking it a bit is fine, but I prefer to stay at 1976mhz which is under 2k but rather this than going to 2100ish for marginal gains.

Everything looks good as long as you are stable.

Thanks for all the help guys. I changed to what you all suggested, seems to be working fine. Also changed the bank cycle time (tRC) to 41 instead of 32 since that is what my ram is rated for. Bios still says its 1333 probably becase its not at or above 800mhz and because its not set to x8, its set to x6.66

RAM speed = bus clock x multiplier
200 x 8, 240 x 6.66, 300 x 5.33..... all DDR3 at 1600Mhz

Note that CPU-Z displays RAM speed before dual data rate
