System Specs:
AMD Athlon XP 2100@2400 (2.0GHz, 133MHz FS
2 Corsair Value 512MB 2.5CAS PC3200 RAM
Shuttle AN35N Ultra (nForce 2 400 Ultra)
I did a SiSoftware Sandra test on my RAM and it did as well as PC2100. I had a friend test his P4 2.8GHz 200MHz FSB and it did as well as PC3200.
Is this because my FSB is 133MHz?
Must I enable Dual Channel DDR somehow?
Help please!

The 2100 Is holding that system back, you need a Barton core processor with the 333mhz fsb or a 400mhz fsb.
The 2500+ 333mhz fsb overclocks really well and is only 80 dollars.

<font face="Arial" size="3"> The AN35N Ultra uses NVIDIA's premier, performance-based chipset. That boils down to some 200FSB CPU and dual-channel DDR-400 lovin'. Shuttle make dual-channel operation foolproof with the colour-coded memory slots. The Athlon XP's architecture doesn't make full use of the possible 6.4GB/s that the chipset can provide, so you may not see amazing gains when switching from single to dual-channel memory modes.</font>

If you have a 133 FSB then this *IS* PC2100 speed. (FSB x 2 x 8 = PC rating).

From memory, your core is running at around 1.6GHz, and you're comparing it to a Pentium 4 running at 2.8GHz - and the P4 uses a quad-pumped FSB - which effectively doubles the memory bandwidth.

Not a fair comparison methinks.

If I get a 200MHz FSB Athlon, what should I expect my RAM speed to be?
3200 MB/s?
Right now its 1045 MB/s.

Also, so a P4 200MHz FSB will max the RAM to 6400 MB/s, not Athlon?

never heard of such a FSB for P-4, i thought 400MHz was the first FSB for a P-4?

Remember all things memory wise p4 are quad pumped.

200mhz is the base speed of the memory for p4s that spout an 800mhz FSB

The 2100 isn't a good chip for overclocking.
With your motherboard and ram, you are basicly underclocking your whole system to allow that 2100 to run right.
The Nforce2 Ultra was designed to let the ponys run on the 400mhz FSB CPU and 400mhz+ Ram The 2100 with its 133mhz FSB is holding your whole system down to 133.

And comparing your system to a 2.8 GHZ p4 isn't even a good comparison at all. In fact, you shouldn't compare the athlons to the p4's at all unless their ratings are the same (IE: 2800+ compares to the 2.8ghz P4)

There is no enable/disable for the dual mode on the nforce chipset, you just have to have two chips of the same type of ram in the appropriate ram slots and it enables automaticly. (On all the boards I've worked with, anyway)

You can't really do a reliable benchmark on your system until you get a processor that the board is designed to run. The smallest processor you should have in that board is probably the Barton 2500+ 333mhz FSB.

I changed some of my settings lately on my CPU:
FSB: 200MHz
Multiplier: 10X
Result: 2.00GHz
Everything is running fine now.
Also, I might exchange my 2100 B for a 1800 B we have.
It is said to run at 2.10GHz instead of this one's 2.00GHz.
My next upgrade to my CPU should be far away.
I plan to get the last Socket 462 (I think its the Athlon XP 3400) when its less than $150.

ahhhh, okay thanx for clearing that.
