Thank you! now I won't have to wait half an hour each time I'll lower the HTT speed by 1MHz.
Here's a question: my max HTT speed seems to be above 266, so I'll have to use a LDTmulti=2 to find it. But then which would be better:
2*300=600 (max HTT speed seems to be under 300)
or 3*266=798
So, does the total effective HTT speed affect system performance?
Are you using a ram divider....

Yes, I'm using a RAM divider of 1:2 to find the max HTT. But I haven't touched any voltages yet.

Well...I seem to have an odd problem:
I set the memory divider to 1:2, the memory timings to 3.0-4-4-8, the CPUmulti to 6.
I set the LDTmulti to 3, and increase the HTT speed, and it hangs between 300 and 310.
Then I try setting the LDTmulti to 2, and increase the HTT speed, and it hangs between 250 and 260! What's with that? Doesn't a lower LDTmulti allow a higher HTT speed if the total effective speed is higher than 800MHz?

Or should I be happy with 300++?

Have you tried upping the LDTs voltage a notch or two?
Also... the nF3 chip might take a liking to a little bump up too.
The HTT of the RAM is not all that picky actually... some have hit well above 800MHz. Somewhere between 600-800ish is the goal.

There's a voltage setting for both LDTmultis and the chipset? I'll have to check that.
RAM at 800MHz? With DDR400? Wow. I don't think my crappy RAM can do that.
If my PC is stable on OCCT with a LDT*HTT=3*300=900MHz, will I one day encounter problems? Or is is okay?

I checked my BIOS and it only has one voltage setting for the mobo: VCC12_12 HT (Chipset) Voltage.
I tried getting a better HTT speed with a LDT=2 by increasing the voltage on the chipset by 0.1/0.2/0.3V, but it still crashed at 260. I guess I'll stick to LDT=3 and HTT speed of 300+.

I've started overclocking my memory: low quality (for OCing) DDR400 with default timings of 3.0-4-4-8 on "auto". I lowered it to 2.5-3-3-5 and overclocked to 243MHz (tested with OCCT). Should I lower the timings? The minimum the BIOS will allow is 2.0-2-2-5.
I've tried Memtest86 but when I booted with the floppy it just said "Loading............" and rebooted. Am I doing something wrong or is it because my floppy is 9 years old?
I've done all this with the 2T setting because I didn't really know what it did. I guess I'll have to do it all over again...

BTW: I just discovered how people get all those rep points... I guess you guys deserve some .

The only way to find out where the better performance lies is with testing. Try all sorts of settings and then give them a test run with a few different programs and note the differences. For me if I can pass OCCT stable then I am happy. It seems for me that if the certain OC can pass OCCT then it can pass anything. I have had prime running for hours on end on a OC and then 5 mins into OCCT it fails. As for your ram timings you can try the lower latencys for sure Do you know what the ram is rated at, speed - timings. The loose timings are not a problem in the real world, you are better off with the ram running at a higher MHZ with loose timings (to a point) then with tight timings and much slower (MHZ).

I was afraid you'd say that .
So OCCT is fine for testing memory too? Nice.
As for figuring out what the best memory clock/timings...Is SuperPI good for finding it out or do I need Sisoftsandra (spelling?)? I have dialup so I can't download most benchmark softwares.

The RAM's HT or LDT is ...
default 4x200=800
They don't take into account for the DDR.
So above an HTT above 200 use 3x up to about 266 or 2x beyond that.

Prime is available there and is good for checking stability of RAM. It is a very small file and will be no worries for your dial up
