2T -> 1T - Causing crashes in games...

[Stangs55]

Okay...so sadly it appears that my 1T timings are unstable in anything besides windows and 3DMark05. When I run Doom3, HL2, etc, the computer locks up in the first frame. Any suggestions?

Here are the shots of my BIOS...right now I'm set to Auto oc the cpu and memory (excpet that I've now enabled 2T timings).

BIOS 1
BIOS 2
BIOS 3
BIOS 4
BIOS 5

Thanks for any advice/suggestions!

Would it help to change my memory voltage settings? to what?

 

[imported_TimJ]

They are rated for 2.75V, so try 2.8V.

Okay so here's a shot of my bios after I've turned off auto oc to change the voltage:

BIOS 6

What else should I change? (I'll try 2.8)

Only change one thing at a time so if your system becomes really unstable or something you know what it is. Do you plan on overclocking?

 

[Stangs55]

not really....but I've changed it from 2.7 and then to 2.8 and the games worked at both settings .

But now...what do I keep it at? 2.8?

Also, since I've disabled Auto OC, the rest of my settings in this page of the BIOS won't be OC'ed at all. Now, I don't want to do any heavy oc'ing by any means....but a slight oc would be nice. Suggestions of what to change?

Keep it at 2.8V. Keep the VCore at the default voltage. For a mild overclock, try bumping the FSB up to 210. You might need to raise your memory voltage to 2.9 to keep it stable at low latencies (2-2-2-5 1T) but there is always the chance it won't be stable at all.

I take it that lowering the multiplier and drastically raising the FSB while using a memory divider is outside of the realm of a "slight OC."

Additionally, slightly bumping the VCore could help stability somewhat. What kind of cooling do you have?

I just turned on the Auto 3% OC and I'm getting:
2678.3 MHz core spped
13x multiplier
206 mhz HTT
206 mhz memory

I'm going to run 3dmark05 cpu tests to see how it handles it.

Should I just disable this though and go another route?

You could turn off auto OC and manually set those settings (make sure the memory is still at 1T). See if that's stable, and if it's not bump the VCore up slightly and try again. It should be fine, as a 3% OC is hardly that much.

If it's stable, bump the FSB up to 208, test again, then 210. I wouldn't push it past 210 if you just want a slight OC. (210 = 5% OC).

 

[Stangs55]

At the current settings, I get up to 54 C max under loads. Can I go much higher?

 

[imported_TimJ]

Maybe. Your system will probably experience instability before it really overheats.

 

[Stangs55]

What about changing the agp voltage from 1.5 to 1.6.....good/bad/retarded?

 

[imported_TimJ]

I've never had that help me with an overclock.

 

[Stangs55]

Woot! Thanks Tim!

I'm now running my DDR @2.8 and have oc'ed to 206.

It's taken my 3DMark05 score from 5377 to 5397
and my CPUMark score from 5468 to 6036

And I am running drivers that are worse for 3Dmark05! (67.20 compared to 66.93)

Thanks for the help!

Please excuse my ignorance, as I have never used an Athlon 64/FX chip, but, what do these "1T, 2T" terms refer to?
