If you're only using that stick it'll be:
Frequency: 200MHz
CAS latency: 3
The rest should be fine on defaults.
Edit: If it still doesn't work bump up the tRAS

DRAM Freq: 200MHz set by me
DRAM Timing Control: Manual
DRAM CAS Latency: 3T Set by me
RAS Active Time tRAS: 6T
RAS Precharge Time trp: 3T
RAS to CAS Delay tRCD 3T
MA 1T/2T Select: Auto
All those things are the defaults except for the two values set by me. Seem correct?
EDIT: Nah, won't post with those settings.
I think I had the same, but on an intel board, I'll check tomorrow after work if you haven't come right.
First step: Load Fail-Safe Defaults, then reboot, and enter setup and Load Optimized Defaults. It will let recover from eventual BIOS upgrade if this step hasn't been done before. Reboot and now you can continue.
Use auto/SPD settings. You might be tempted to use performance mode, but this chipset is sensitive. Gigabyte board is known, it might never recover from this mode. One died in my hands.
If memory sticks frequency differ, they might have the same SPD defined for lower (common) frequency, then no problem. In not,
- insert slower SIM to the first slot, or
- manually tune RAM timing for slower stick (not recommended)
To determine SPD timings, boot from Hiren's CD and use CPU-Z by example. Compare current timing with SPD data.

You can try holding the insert key while you power it on, should safe boot then
Not in this case, it is documented by number of users. No recovery. Something was damaged permanently, Bus timing blowing data buffers by example.
No go on this.
Thanks kilo
There might be some hope. Lady works half day for a doctor and apparently the office PC bombed and they got a new one, the old one is still lying there. Knowing how these scheisters operate there might be very little wrong with the old one (hoping it's a dead PSU, or maybe the new pc came with a software 'upgrade') and she's gonna ask if she can have it. Maybe I can cobble something together. She'll let me know later, crosses fingers. If this pans out then I can give the old one to my domestic worker as she's been asking, I've got a spare 17" crt to boot.
Yeah she's still broke
I'm hoping to see if we can't get another PC for her, will know later.
This MB is very finicky with ram, would hate to buy that and then it does not work. I have a working 512MB stick here that will not work in this machine for example.
Hey Ponder... mobo's tend tie RAM to CPU FSB. 266/333/400 DDR determined by CPU.
What CPU in there ... ?
3GHz but it worked fine before with a mix of 333 & 400 ram, now only the the 333 is left.
Not this one. In auto mode it selects optimum (the fastest) RAM speed based on SPD. Not sure if found two different modules; it picks up the slower one or just looks for one slot. Even if picks up the slower one, what happen if DDR400 has incompatible timing in DDR333 mode?
Lastly, old mobos don't like high density chips. Typical example is i440BX chipset which detects such modules as having half capacity. And if you mix it with other modules it appears to work, but memory test fails or simply hangs due to the conflict on the memory bus. Only very early 256MB modules work on these boards, it was pain in ass sometime ago to find a right memory for my Asus P2B.
