nb/cpu volt - Page 2

You probably need to check the RAM settings. When OC'ing via the FSB you need to change your RAM frequency. Since I'm at 250 FSB I can get the same stock settings on my RAM, which are at 1333mhz, by lowering the frequency in BIOS. So normally at 200 FSB I would be at 1040 (idk exact number) now its at 1333mhz with 250 FSB. Hope this helped.

musnt the divider be a whole number? so its 250x3x2=1500mhz? set it in 1333 in the bios now or at stock? the number go up by it self when i up the bus, so at stock i did put it at 1333

Your RAM is running at 1732mhz so you are aware of that. At least I think, I'm new to RAM.

No the Memory Divider is actually a ratio of DRAM to HT REF CLK (FSB as some are calling it)

1600 / 2 = DRAM freq = 800/ 200 HT REF CLK = 4:1
1333 / 2 = 666Mhz = 666/200 = 3.33 = 10:3
1066 / 2 = 533Mhz = 533/200 = 2.66 = 8:3


Now as I have stated with a HT REF CLK of 250Mhz - i can see you gettng 1600 Mhz Maybe 1665Mhz but if you have set 1600 Mhz with the HT REF CLK at 250 the memory divider is set at 4:1 ie 250 x 4 x 2 = 2000Mhz.

That is why I asked you to check if CPU-Z is seeing you RAM as 1333, 1600 or 2000!

Your HT Link needs to be dropped immediately. 1800-2100MHz or so is optimal for HT Link.

You need more CPU-NB voltage for 2600MHz on the NB. You also need a bump in CPU-NB voltage when using 4 DIMMs.

ah okey you see the pic from CPU-Z there, or do you want the pic with the stock ht ref?


and pio, how much volts do you think is good?

OK - you are now running a 260Mhz HT REF CLK!

Yes - you are correct 1733Mhz

260 x 3.33 x 2 = 1733Mhz
if you want to stay at 260 try
260 x 2.66 x 2 = 1383Mhz

Also as Pioneer stated - drop to 2000Mhz for the HT Link
You would be advised to run your NB at 2400Mhz and add some voltage to that to ~1.15V
add some voltage onto your CPU-NB voltage ~1.2V
and at 1733Mhz - you need to run DIMM Voltage 1.65V at a min maybe more!

No reason to drop your NB speed down. NB speed is just as important as CPU speed.

Just give her more CPU-NB voltage until its stable. You're good up to 1.45v CPU-NB voltage.
