Opteron 165 won't overclock... Confused!

[giantpinkbunnyhead]

Tonight I tried to OC my Opteron 165. I took the advice of many and began to isolate things one at a time. First I sought to find the max HTT. I set the Ram divider to 1/2, lowered the LDT multiplier to 3x, and kept the CPU Multiplier at 9x. Under these conditions, my computer won't even post above 230 MHz HTT. Am I doing something wrong?

My mobo is a DFI Lan Party UT Ultra-D, Bios date 6/23/05.
RAM is OCZ Platinum Rev. 2, 2x512, DDR400.
Cool 'n Quiet is Disabled.
All other RAM timings are stock settings.
Voltages are at stock settings too, I think Vcore is 1.35.

Am I not understanding something?

There is something wrong. I was able to get my ultra-d up to 290ish stable though not farther yet. So far my oc is 9x280 = 2520. I would play around with the vcore, though I only had to up mine to 1.4 after 260 htt...

you may have to up voltage to get cpu to post at 230 x 9. lower the cpu multi to 8 or 7 and then try to find the max htt. also try with one stick of ram in.

 

[adiabaticgfx]

Ya your chip voltage is what's probably limiting you, drop the multi to 6X or so when finding the max HTT or increase your voltage and keep going.

 

[keidanny]

you should easily be able to do 230htt on stock voltage. do you have pci lock on?

 

[freddy418]

you need to loosen the timings on that ram.

He doesnt need to loosen timings if he is running a 1/2 divider.

THanks for the suggestions. I'll try some of them when I get home later today.

One interesting note... in a bit of frustration, I just took a stab in the dark and set a bunch of things at once. It booted right up, with no problems, first try.

I got it with 280x9 for 2520 MHz;
3/4 Ram Divider
LDT multi at 3x
Stock RAM timings
Stock voltages

Only problem is, it's unstable. I didn't run Superpi for long; it did 2M digits repeatedly; but the OCCT torture test causes a crash in 44 seconds. Did not run any other tests. My mobo temp peaked at 55*C after all the testing, and the CPU's peaked at 48-49 C. These temps are according to Everest and SpeedFan. I'm on stock cooling, but would like to upgrade to better air cooling.

Since I didn't isolate anything to arrive at these settings, I have no clue where the instability lies.

update, As i'm getting this board soon

Probably voltages. Increase both voltages (vcore and chipset) one or two notches ..

 

[themusgrat]

Yes, voltages are probably the problem. Some DFI boards randomly take added voltage to OC well, but not many. Set vcore to 1.450,and chipset to 1.6. Do try and find the RAM's max, though, as it is nice to know.

can i ask you a question?

do you have pci lock on on your board?

*think think*

oh yeah, just in case you didn't see what board he has, refer to post #1.
