Why would you want to?

In any case, I think the lowest value you'll be able to set with that CPU is 6 (as was the case with many Core 2 CPUs and CPUs based on it). It depends on the BIOS on where that would be, but generally there's a CPU ratio control somewhere. ECS is usually a budget brand so it may lack it, but I'm unsure of that exact board.

becus somone else told me to lower the multiplier then put more bus speed in my cpu im trying to overclock my e2140 1.6ghz im at 1.7ghz right now

It's going to depend alot on the board (and BIOS settings) and exact RAM you have on how far it'll go. If you're running the stock Intel CPU cooler, watch temperatures, but I had a Pentium Dual-core E2160 @2.7GHz on the stock Intel cooler so even that should suffice at these speeds so long as you're not expecting beyond 3GHz.

That CPU shouldn't need it's multiplier lowered. In fact, if you do that, you'd need to raise the FSB even more to compensate and break even. Don't lower it.

How is your 1.5GB of RAM situated? How many modules, and what is the exact RAM (speeds, ratings, timings, voltage, etc.)?

Other than that, you pretty much slowly raise the FSB until the RAM and/or board meet their limit, as I'm sure one or the other will before the CPU since it seems like a budget board and RAM.

Edit: Your board does 533MHz FSB, and that CPU is 400MHz FSB. So, assuming the RAM is at least faster than slowest of slowest DDR2 available (400Mhz), you're looking at at least an overclock of 266MHz FSB (533MHz RAM/1066MHz rated FSB), which is a 2.128GHz speed. Post a screenshot from CPU showing your memory tabs. If it's 533Mhz or greater, I'd say go straight for 266MHz FSB and keep the RAM at 533MHz. The board does it, and the CPU has a 99% chance of doing it on stock voltage.

Sorry for the late reply.

Okay, you have mismatched RAM, but you should be able to do it.

1. Set your RAM timings to 4-4-4-12. It is currently doing 4-3-3-9. I do not have experience/knowledge with your board/BIOS, but look for RAM timings/adjustments.

2. Set the RAM voltage to 1.8V. If you only get choices of "normal" and "+0.1V, +0.2V", etc., set it to normal.

3. Set the FSB to 266MHz.

4. Check your RAM speed after putting the FSB to 266MHz. If your RAM speed is HIGHER than 266MHz, see if you can adjust it. If not, and it's higher (like at 333MHz), adjust your timings again (as you did in the first step) to 5-5-5-15.

4. I'm not sure what you voltage is set at now (I can see what CPU-Z shows, but not what it's set at). I'm going to guess ~1.35V-ish. Try setting the CPU voltage to ~1.3625V. That is a 65nm CPU so they can take a bit more voltage.

5. Report back about it went?

This will net you a 2.13GHz clock speed if successful. I see you're at 1.8GHz so you're just under halfway there already. Your board is only rated for 533MHz FSB speed, so going higher that it's rated, especially on a budget board, is a gamble and will involve more work, like more RAM tweaking, Northbridge voltage, etc. The next step would be to try a 300MHz FSB (2.4GHz result) and then a 333MHz FSB (2.66GHz result, which is a healthy ~1GHz+ overclock over stock). Again, the boar, and how it sets your RAM (ratio and timings) is what you're mostly at the mercy of. That's the trade-off with budget boards. The CPU, almost for sure, can do it.

Just monitor temperatures (try to stay below ~65C maximum), and make sure the CPU stays under ~1.45V, and the RAM under ~1.9V (not sure what that stuff can take as it seems generic), and you shouldn't damage anything.
