The 4 pin headers are backwards compatable with 3 pin fans. There's a key on the header that positions the connector correctly.Quote:

just connect the 3pin header to the 4pin header. and there is only one way to connect it right. i dont think it's possible to go wrong there.Quote:

thx, I see that 40mm fan will fit in the middle just fine. But will it be enough?Quote:

Enough for what? :)Quote:

One question, how do I change the fsb:dram ratio? I have it at 2:3, trying to get it to like 5:4 or something.
Im coming from ddr1 so everything is very different.
This isn't directly selectable in BIOS. With most chipsets the setting is done automatically by the BIOS based on the current FSB. I don't know if anyone has started testing this. But the best way to find out how to manipulate it is to run memory bandwidth tests as you run up the FSB. jumping to the 1333 strap from 1066 will result in a hit to bandwidth and latency on the memory. I'm not sure but i also believe that everest will report the current strap.Quote:

cpuz?
everest?
speedfan?
memset?
sandra?
etc.
Yes i saw that post, but i dont really understand it.Quote:

all of them are compatible with 800MHz ram. by changing the reference frequency and memory frequency you are setting the divider. It's not the most user friendly method of setting this because it makes you do some math, but it works. Use the table in the post listed to set your divider, then do the math to figure out your true memory frequency.Quote:

Im not sure Im doing this right, I keep getting decimals.
for instance, say you want to run DDR2-800 with a FSB of 300. That would require a 3:4 divider on your memory. 300/(3/4)=400*2(because its ddr)=800Quote:

to get this divider you can use the setting below:
REF MEM RATIO
200 533 3/4
also any time you start dividing fractions, you will end up with a chance decimal. just round to the nearest whole #
Yeah i just figured that out... im an idiot =)
Box retail.Quote:

Memset. No. Works great.
Sandra: Yes: You can run the benchmarks but if you try to read MB info, instant hang.
To recover from a vcore reset, you MUST remove all power from the MB. I.E. unplug or power off the PSU and wait for the green light on the MB to go out.
i cant figure this out. im using the latest bios and i cant hit 440FSB at maximum MCH/FSB voltages. it just doesnt POST or freezes at POST.
BUT im perfectly stable at 400FSB at minimum MCH/FSB voltages.
it seems like the vcore to the CPU is not changing after adjusting some extra vcore.
Did you just jump to 440 or did you work your way up to it? I did find that with this board more voltage isn't always a good thing. At several 400+ steps, lowering the voltage actually made things more stable.Quote:

yup, jumped from 400 to 440 :P i will try to figure it out and tomorrow im probably gonna test if the vcore is raising or not after adjusting to higher in bios.Quote:

I tried getting it off tigerdirect but their site kept on saying the info for the card was wrong so I couldn't use them, the exact same info worked on newegg though. I think the amazon sales is actually through tigerdirect if you look at the 17 used or new section. Damn extra cash spent better be helpful if anything goes wrong.
I am now or more like in 3 days will be a proud BX2 owner anything I need to know? Haha just kidding I will read through the thread again but actually does anyone if super talent ram works fine with this mobo?
