Opteron 180 stuck @ 234

[mrbadnback]

I have a problem with the OC and can't figure out what's wrong. SYSTEM in SIG.

I have gotten my Opteron 180 to 12x 234 with the VCORE at 1.35v and @1.02% with DRAM set @100 1/02 and the LDT/FSB set to 2x. BUT I can't get the FSB past 234 stable even with the increase to 1.04%. Since I have the RAM out of the OC and lowered the HTT to the 2x what can be causing it not going any higher? Is it just the CPU won't go any further or should I just raise the Special VCORE % higher? I figured that if it didn't allow me to go further with the increase to 1.04% that increasing it further wouldn't matter. IS it the CPU or do I have other options.

Try these.

Max async latency = 8ns

Dram response = normal

Read Preamble = 5ns or 6ns

[mrbadnback]

Is that really going to matter that much since I have the RAM set to 100 1/02?

[MACarter02]

lol. try it. Look at the number of posts Sharp has, and at his OCDB entries. And then try it!

[mrbadnback]

I'll have to try it tomorrow when I am able to get back to my system. I sure hope it works! I had a Opteron 148 in the system before and had it OCed to 264 x11@ 2.904Mhz so I was hoping that the 180 would OC better than it has so far.

I tried making those changes and it didn't help out any "Sharp" I am enclosing my RAM settings and what I have it set on now. Maybe you can see a in the settings that I have a way to get my OC higher.

wow... 2.8 GHz on nearly stock voltage.

[WR6X]

Maybe upping your LDT Volt Control.

 

I'm running 3GHz (250x11) @ 1.34V with my LDT Volt @ 1.34V.

[ebdoradz]

try another divider the 100 1/02 opteron usualy dont like divider under 3/4

 

at least mine refuse to post with anything under that

[MACarter02]

my 165 is the same way. dont know about the 185 though

[mrbadnback]

I'll try upping the LDT volts and trying something other than the 100 1/02 setting for the RAM when I get to my system later today. I have been using the 100 1/02 because of the DFI OCing guide to just OC the CPU first and let the RAM out of it but I guess that isn't working. I thought that the OCing guide was the way to go but maybe it isn't that good on some of the DFI MB's. I have tried upping the VCORE to 104% and it seemed to do nothing since the out come was the same. I even tried raising the RAM voltage to 2.72v froom the 1.66v but it didn't seem to do anything either.

It is running now at 234FSB x4HTT VCORE 1.35v@ 102% with the same RAM settings but @ 166 5/6 I tried 180 9/10 but it didn't pass OCCT. It passes memtest with no problems.

[Sharp]

Sorry for not getting back sooner.

 

TRC...........07 change to 11

TRFC..........11 change to 14

 

And try running the memory as close as you can to 200Mhz (400DDR).

Lower your multiplier (CPU ratio) to something such as x8.

 

Dual core means it requires a lot more power and the memory controller/memory settings may be running low but the actual memory controller isn't.

 

Should it fail start increasing the Vcore voltage and monitor the PWM and CPU temps. (What are these temps at the moment?)
