any one know what the correct multiplier/FSB speeds are? ive just noticed that mine is running at `1.8ghz, which isnt right i know that much, but according to bios it should be running sweet :S any way can some one plz help
Huh? Your running a 2500+ Barton Athlon XP, what's this got to do with a 3200+ AMD64?
A 2500+ runs on a 166 FSB with a multi of 11 for 1.83Ghz.. at 1.65v - that's how it's always been..
or are you trying to overclock it?
If your trying to overclock it to 3200+ speeds (2Ghz).. then try increase your FSB to ~180Mhz, OR if you can unlock the CPU can just increase your multi to 12.
I think the BIOS has told the CPUID program that its a 2500+ rather than, in reality, it being a 3200+. Either that, or he got ripped off.
This happened with a few BIOS revisions on a variety of Socket A boards when the XP's were available, where you'd set it to 3200+ and it would set the clock rate and multiplier to a 2500+ CPU - whether it was or not.
I'm hoping he has something easy, like an Abit board or any equally easy nForce2 board... so he can set it all in the BIOS without fiddling with jumpers and dipswitches :|
How do you know for certain it's not a 2500+? I'm not doubting you, but yeah..
Got a model of the DFI board? Some of the Nforce 2 boards did come in jumperless and jumpered versions, and I believe some in both. Given the jumpers are physically on the board, they take priority over the BIOS, so even if you set it in BIOS but have jumpers set differently, thatd stop it.
Other then that, I cant really see why it wouldn't let you, bad BIOS version? Tried putting the CPU back in? Reset CMOS?
Edit: hmm maybe Nforce 2 was jumperless.. mm I swear some weren't.. anyway just looked at all the DFI socket A nforce 2 boards and they are all set from BIOS, so that's that idea out the window.
thanks for replies guy, but its all fixed now, for some reason the bios was setting the "default" multi too low :S but i changed it so its all good now :D
The AXP used DDR so the effective theoretical bandwidth is doubled. The frequency of the FSB remains the same, but, it acts like its running at 400Mhz - it is not truly running at that speed.
Intel uses this as a marketing technique and label their devices accordingly: 400Mhz FSB, 533Mhz FSB & 800Mhz FSB. These are actually quad-pumped at the Bus Interface Unit.. the actual FSB's are: 100Mhz, 133Mhz and 200Mhz, respectively.
Easiest way is to pull the heatsink off (with the computer off) and check the number on the chip (including the actual model number thats around 10 digits long) enter that into the AMD website and it will tell u exactly what you have and what it should be set to and what Mobos will give the best performance with that chip.
