KX333r versus PC2700 memory

As I understand it, the CPU interacts with the nothbridge on 133Mhz but Memory with the northbridge with 166. Thus achieving a bottleneck. Is it not improving performance putting in PC2100 mem on 133Mhz?

Mind you, I saw some articles on putting the CPU fsb to 166 and lowering the multiplier so the original speed is reached but no longer having this bottleneck. The only problem however is that if I do so, the system wouldn't even startup.

You'd have to have your Athlon unlocked so you can change the multiplier value and still have it POST.

Txs.

I thought as much. Thats why I thought of putting in PC2100 mem. At 1st glance it looks like downgrading but cause of the traffic between CPU to Northbridge at 133Mhz  then from Northbridge to MEM at 166. I thought keeping everything at 133 could improve performance.

Anyone ideas/suggestions?

I'm basically doing exactly that, except i'm overclocking very slightly. I have a XP1800+, which is 1533MHz at default, and i'm running it at 169x9.5=1695, and it's much faster than if I were running it at 133x12. Only thing is that some boards don't support a 1/5 divider, which puts your pci devices far over their default speeds. My system runs fine at this fsb, but nobody has been able to ascertain whether or not the GA-7VRXP has a 1/5 divider or not, which is the board i'm running. I have a feeling over 153fsb the 1/5 kicks in, but there is much debate about that on this  board. Ah, i'm going off topic.

[EDIT]I'm sorry, I misread your post. I thought your were talking about increasing your fsb, not lowering your memory. SORRY!!!

I still dont get it, heres my setup:

Abit KX7333r
2100+
128Mb Ti4200
512Mb PC2700 Samsung
Array1: 2 x Maxtor 40Gb 7200/133
Array2: 2 x IBM 40Gb 7200/100

On PCMark2002 Benchmark I get:

CPU: 4924
MEM: 2976
HDD: 454

When I do a compare with other systems they all run approx 10% faster.

To my knowledge I installed all the lattest drivers for MB (4in1), Ti4200 and still ??

Any ideas whats wrong?
