Memory on ASUS P5Q Pro timings/channel Question


scp89

Recommended Posts

Hi everyone....

 

Building a new system...here is the core system...

 

- ASUS P5Q Pro

- Intel Core 2 Quad Q9300 Yorkfield 2.5GHz 6MB L2 Cache LGA 775 95W Quad-Core CPU

- CORSAIR DOMINATOR 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 1066 (PC2 8500) Dual Channel Kit Desktop Memory

- ASUS EAH4850 TOP/HTDI/512M Radeon HD 4850 512MB 256-bit GDDR3 PCI Express 2.0 x16 HDCP Ready CrossFire Supported Video Card

 

My question pertains to the Memory...I read the manual and I'm a bit confused. Do I put the 2 sticks of memory in the the 2 'yellow' memory slots? or am I supposed to populate just the 'A' channel.... Channel A DIMM_A1 and DIMM_A2 (A1 is yellow and A2 is black) and similarly Channel B DIMM_B1 and DIMM_B2 (B1 is yellow and B2 is black)

 

this is where I got confused:

• You may install varying memory sizes in Channel A and Channel B. The

system maps the total size of the lower-sized channel for the dual-channel

configuration. Any excess memory from the higher-sized channel is then

mapped for single-channel operation.

• It recommended that to install the memory module from yellow slots for

better overclocking capability.

 

also anyone have any suggestions for my bios settings for the cpu/memory? timings from the memory manufacturer are listed as 5-5-5-15-2T / Cas 5 / 2.1 Volts

 

Much appreciated in advance for the help....

Install the DRAM into the yellow slots.

Download Memtest86+ V2.11 from--->

and extract the ISO image. Burn the ISO image to an CD-ROM disk.

Download CPU-z from-->

Set one stick in slot 1 (Closest to the CPU) and one stick in slot 3 (Yellow Slots) enter BIOS, load setup defaults, save setup defaults and set to these values.

 

Enter your BIOS and set to these values:

 

AI Overclock Tweaker

[b]Configure System Performance Settings

Ai Overclock Tuner = Manual
CPU Ratio Setting = Auto
FSB Frequency = 333
PCI-E Frequency = 100
FSB Strap to Northbridge = 333

DRAM Timing Control = Manual

DRAM Frequency = DDR2-1066
DRAM Command Rate = 2N
DRAM Timing Control = Manual
CAS# Latency =  5
RAS# to CAS# Delay = 5
RAS# PRE Time = 5
RAS# ACT Time = 15
Row Refresh Cycle Time (tRFC) = 60 
All Else to Auto

DRAM Static Read Control = Disabled
DRAM Read Training = Disabled
Mem. OC Charger = Auto
AI Transaction Booster = Disabled
Relax Level = 9
CPU Voltage = Auto
CPU PLL Voltage = Auto
FSB Termination Voltage = Auto
DRAM Voltage = 2.1v
NB Voltage = Auto
SB Voltage = Auto
PCI-E SATA Voltage = Auto

Loadline Calibration = Auto
CPU Spread Spectrum = Disabled
PCIE Spread Spectrum = Disabled
Clock Over-Charging Voltage = Auto
CPU GTL Volage Reference = Auto
NB GTL Voltage Reference = Auto

Legacy USB = Disabled

 

Run Memtest for two full passes. If stable, Enter Windows, run CPU-z and post screenshots of the CPU-z's CPU, Memory and SPD tabs.

 

Results?

Sorry to ressurect an old thread. It's me again!

 

Bought the new Mobo and installed it.

 

Are these the correct settings for my memory and board? I've looked in the BIOS and certain options are not there:

 

DRAM Command Rate

Relax Level

CPU GTL Voltage Reference

NB GTL Voltage Reference

 

Those are the ones I remember. I even tried to configure it in case it opened up new options but those are definitely not there. Do I need to flash the BIOS?

 

System is running stable ATM. However it is a bit sluggish when loading windows and there is a very notable performance decrease in GTA4 graphically compared to the last motherboard.

 

Any ideas?

Run Memtest for two full passes. If stable, Enter Windows, run CPU-z and post screenshots of the CPU-z's CPU, Memory and SPD tabs. This gives you a light overclock to 3.6Ghz and should speed your memory transactions quite a bit. Keep in mind that these optimizations may not work. It's dependent on the CPU and memory controller as well as the memory.

Results are in:

 

Overclock was successful. However I made a couple of notes.

 

1. I had to drop the DRAM frequency to DDR2-961mhz. There was no option to set 1066. It was up or down so I chose to clock it down for safety.

 

2. During Memtest it reported the tested memory as 3327M

 

3. Each test took 5 mins longer than on my old board.

 

Both passes completed with no errors.

Since you are running with a 32bit OS you do not want to set the memory remap to 4GB as you will lose some memory that way. You are at the correct settings. You can, if you wish, set the memory remap in the BIOS and retest with Memtest and then disable it before entering Windows.

 

It looks as though you are fine.

I'm at my wits end with this.

 

I'm getting terrible performance from this system. Games average at 15fps. O/S runs slowly and browsers seem to stutter. 3dmark06 gives my system an awful score and it averages 15fps in the tests.

 

I don't know what's wrong with it anymore.

 

On the last board processing and graphics were lightning quick. On this I get no performance at all. I have no idea what I'm looking at as the cause.

Download Everest Trial Version from here -->

Install Everest and right click on the (i) icon in the system tray. Choose Tools --> Cache and Memory Benchmark. Run the Benchmark and post the finished screenshot.

Download CPU-z from
.

Post screenshots of CPU-z's CPU, Memory and SPD tabs.

 

Keep in mind that you are not running a video card that will accept a 24" monitor maximal settings and game. With that video card I would set to no higher than 1280 X 1024 and mid eye candy.

I've set the cpu back to 3.00ghz and the memory is currently in slots 2+4 as I was trying to eliminate causes. All other settings are as specified above.

 

This card and cpu were running GTA4 and COD4 brilliantly in 1920x1200 with decent settings on the last board. I know it's not top of the range but it's no slouch either.

 

I wish I could demonstrate the performance difference!

A quick question:

 

My graphics card does not have a connector for external power supply and it relies solely on the PCI express slot for power. Could it be that it's not receiving enough power from the board?

 

It's not likely. If the card needed the secondary power connectors then the manufacturer would have added them.
