Need help reaching 3.0ghz from 2.84 (Opteron 148)

Youneex · 19-January-06, 01:30 PM

I've got an Opteron 148 CAB2E, I've been fairly happy with it. Load temps are at 37c, Idles around 27
DFI Expert
I've got 2 x 1GB OCZ Gold GX XTC PC4000

Currently I'm running at 2.84ghz at 1.42v, but I'd love to reach that 3.0ghz while not burning out the processor

Here are my bios settings:

Genie BIOS Settings:

FSB Bus Frequency - 258
LDT/FSB Frequency Ratio - Auto
CPU/FSB Frequency Ratio - 11
PCI eXpress Frequency - 100Mhz

CPU VID StartUp Value - Start Up

CPU VID Control - 1.425
CPU VID Special Control - Auto
LDT Voltage Control - 1.30v
Chip Set Voltage Control - 1.62v
DRAM Voltage Control - 2.87v

DRAM Configuration Settings:

DRAM Frequency Set - 200=RAM/FSB: 01/01
Command Per Clock (CPC) - Enable
CAS Latency Control (Tcl) - 3
RAS# to CAS# delay (Trcd) - 4 Bus Clocks
Min RAS# active time (Tras) - 6 Bus Clocks
Row precharge time (Trp) - 03 Bus Clocks
Row Cycle time (Trc) - 07 Bus Clocks
Row refresh cyc time (Trfc) - Auto
Row to Row delay (Trrd) - 02 Bus Clocks
Write recovery time (Twr) - 02 Bus Clocks
Write to Read delay (Twtr) - 02 Bus Clocks
Read to Write delay (Trwt) - 03 Bus Clocks
Refresh Period (Tref) - 3120
Write CAS Latency (Twcl) - Auto
DRAM Bank Interleave - Enabled

DQS Skew Control - Auto
DQS Skew Value - 0
DRAM Drive Strength - Auto
DRAM Data Drive Strength - Auto
Max Async Latency - Auto
DRAM Response Time - Fast
Read Preamble Time - Auto
IdleCycle Limit - 256 Cycles
Dynamic Counter - Disable
R/W Queue Bypass - 16 x
Bypass Max - 07 x
32 Byte Granularity - Disable(4 Bursts)

I've played with ram dividers and such, and that didn't really yield results. Usually I'd just blue screen during Windows boot, or receive some other debugging output, or automatic reboot.

LDT/FSB Frequency Ratio - Auto

Change that from Auto to 3

Also bumping the cpu voltage, ldt voltage, chipset voltage, and ram voltage a bit should help. Remember to use a ram divider as well.

I have a 146 CABYE Running at between 3.00 and 3.150Ghz

My core voltage is 1.55 with a memory divider of cpu/14.

The temps will get higher with more voltage but good cooling should take care of that

Good luck!

About the cpu voltage, which is correct, the one in BIOS or the one displayed by cpu-z or cbid?

I go with the one in the BIOS, however there should not be too much of a diff...(mine is the same newayz)

Did those things, and used a ram divider.

273 x 11, 9/10 ram divider, increased voltage. Bluescreens through windows boot, and I'm running it at 1.55v.

Is she getting too hot? what kind of cooling are you using?

I've got a Thermaltake Big Typhoon mounted on it. Temperatures stay below 40c. Usually 37 - 38c on load.

cpu-z and cbid are usually lower for me. Like now, 1.4 bios, 1.392 software. ????

that weird,

I would trust the BIOS more as far as Voltages.

have you tryed lowering the HTT speed

Sounds like you are changing settings in the Bios and hoping it will boot...this is not the best way to OC.

You have to take it up slowly, test for stability and then go up another notch (5MHZ at first, then 2MHZ as you aproach the limits of the CPU)

Use a bigger memory divider (2/3=166) and start from say around 2.8GHZ and 1.45v, adding voltages as needed.

I did this and it seems like I max out around 2.956ghz at 1.56v. Prime95 fails almost immediately if I push it any further. I tried various amounts of dividers, and I even loosened timings, but I don't think the memory is the problem, as I can run it stable at 278mhz on 3-4-3-6 timings.

$SOLID$ Necro · 21-January-06, 12:07 AM

To elinate the question of the Memory, drop the Multiplier to 9x and bump up the FSB until it reaches over 300FSB..if it's stable then you can count that out.

It could just be you have maxed out your chip jusding by how much voltage you've tried, not all of them will do 3GHZ.

If you can open the windows and get you ambient temps down, it will probably do 3GHZ, but that is not very practical...
