slow memory and OC

At the moment I am running a XP2400 but I have PC2100 memory. I have had trouble getting this sys to run past a 140 FSB, and I assume the memory is at fault.
I know it is better to OC with as high a FSB as possible, but would it be worth running a lower FSB and higher multiplier to get a faster clock? It seems that this would help avoid the slow memory issue for the moment, until I can afford to upgrade the memory.
At the moment I am running 140x15 for 2100mhz @1.7v
Thanks for the input.

yes while your waiting to get faster ram u can always up the mutliplier it wont hurt

I think increase in cpu speed affects overall system speed a lot more than increased ram speed.

Well I upped it to 140x16 for 2240 and it is running P95 as we speak. so far so good

cool. what voltage is that at?
my 2400+ is Prime95 stable with 1.65v at 2200Mhz, but at 2300, I need 1.75v.

currently 1.70v (per Winbond Hardware Doctor) although my BIOS setting is 1.75v (board undervolts)

that's pretty good.

Don't go too high with Vcore but don't be too shy either:

If your memory can handle the heat turn up your VDIMM, you should be able to get your ram to higher FSBs with tighter timings.
Or just crank it to the max and kill your DIMMs so you have an excuse to buy faster ones .

-Overcrocked

So, to follow up with a sucess story- I finally had a good BFO (blinding flash of the obvious) about the whole overclocking picture. By adjusting the FSB/RAM ratio (currently @ 5/3) I was able to push my FSB to 220! Currently P95 stable @ 220x10.5 for 2310mhz (although running a bit hot)

Pretty happy!

Yeah, yup, I was pretty happy with my 208 FSB an' my PC2100 RAM until I discovered that in real life 100% in sync is what it's all about, not benchmark scores. Again, towards the end of this thread, I saw the light and went back to 152 FSB:
