Settings for RAM to run at 1066

Recommended Posts

I'm having trouble getting it running at 1066 rather than the default 800 it's currently running at.

 

Now these are the settings I've tried,

 

AI Overclock Tuner - Manual

CPU Ratio Setting - Auto

FSB Strap to Northbridge - Auto

FSB Frequency - 333

PCIE Frequency - 100

 

DRAM Frequency - DDR2-1066

DRAM Command Rate - Auto

DRAM CMD Skew on Channel A - Auto

DRAM CMD Skew on Channel B - Auto

DRAM CLK Skew on Channel A - Auto

DRAM CLK Skew on Channel B - Auto

DRAM Timing Control - Auto

DRAM Static Read Control - Auto

AI Clock Twister - Auto

AI Transaction Booster - Auto

 

CPU Voltage - Auto

CPU PLL Voltage - Auto

North Bridge Voltage - Auto

DRAM Voltage - 2.10V

FSB Termination Voltage - Auto

South Bridge Voltage - Auto

SB 1.5V Voltage - Auto

Loadline Calibration - Auto

CPU GTL Voltage Reference - Auto

NB GTL Voltage Reference - Auto

DRAM Controller Voltage REF - Auto

DRAM Channel A Voltage REF - Auto

DRAM Channel B Voltage REF - Auto

 

CPU Spread Spectrum - Auto

PCIE Spread Spectrum - Auto

 

 

Now with these settings my machine would POST and boot to windows, however when I ran 3DMark 2006 the machine froze and crashed, then would no longer boot to Windows.

 

I also tried the following settings,

 

 

AI Overclock Tuner - Manual

CPU Ratio Setting - 7.5

FSB Strap to Northbridge - Auto

FSB Frequency - 333

PCIE Frequency - 100

 

DRAM Frequency - DDR2-1066

DRAM Command Rate - 2N

DRAM CMD Skew on Channel A - Auto

DRAM CMD Skew on Channel B - Auto

DRAM CLK Skew on Channel A - Auto

DRAM CLK Skew on Channel B - Auto

DRAM Timing Control - Manual


  • CAS# Latency - 5
    RAS# to CAS# Delay - 5
    RAS# PRE Time - 5
    RAS# ACT Time - 15
    RAS# to RAS# Delay - Auto
    REF Cycle Time - 50
    WRITE recovery Time - Auto
    READ TO PRE Time - Auto

DRAM Static Read Control - Enabled

AI Clock Twister - Auto

AI Transaction Booster - Auto

 

CPU Voltage - Auto

CPU PLL Voltage - Auto

North Bridge Voltage - Auto

DRAM Voltage - 2.10V

FSB Termination Voltage - Auto

South Bridge Voltage - Auto

SB 1.5V Voltage - Auto

Loadline Calibration - Enabled

CPU GTL Voltage Reference - Auto

NB GTL Voltage Reference - Auto

DRAM Controller Voltage REF - DDR2-REFF

DRAM Channel A Voltage REF - DDR2-REFF

DRAM Channel B Voltage REF - DDR2-REFF

 

CPU Spread Spectrum - Auto

PCIE Spread Spectrum - Auto

 

 

However like this, my machine would POST, but not boot.

 

I'm not an experienced Overclocker, and have never overclocked my RAM before, but I'd really like to get it running at 1066 rather than the current 800MHz. Any help would be vastly appreciated!!

Download Memtest86+ Version 2.11 from--->

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

Download CPU-z from-->

Shut your system down. Insert a single stick in slot 2 (Second from the CPU)

 

Enter your BIOS. Load Setup Defaults. Save Setup Defaults. Set to these values:

Shut the system down. Insert the second stick in slot 4, save settings and boot to the Memtest CD for two full passes, then (If Stable) enter Windows and post screenshots of CPU-z's CPU, Memory and SPD tabs.

I put in the settings you suggested, though with the following exceptions.

 

REF Cycle Time - I had to set this to 65, not the 66 you suggested. The BIOS will only allow values divisible by 5, and it just gives a list to choose from, doesn't allow you to enter a numerical value.

 

North Bridge Voltage - I left this at Auto. I didn't have an option for 1.30V, only 1.29V and 1.31V.

 

I rebooted and ran Memtest, and with the Overclocks I got a few hundred errors from test 5 onwards. I then went back to the BIOS, reset all the settings back to their default Auto, re-ran Memtest and had no errors.

 

I've also attached my current CPU-Z values for the memory and spd tabs.

Also, if it's any help I'm running BIOS version 0701 which is I believe the latest BIOS for this board.

Well I increased the Northbridge Voltage to 1.31V, and whilst I still got errors it was FAR less than at Auto. I took it up to 1.33V, however I got more errors than on 1.31V with that. Memtest is currently running with a NB Voltage of 1.35, and if that doesn't work I'll try 1.37V and 1.39V, though that's as high as it'll go without exceeding 1.4V (Next increment is 1.41V) and see how they go too.

 

 

UPDATE -

 

I've tried 1.29V, 1.31V, 1.33V, 1.35V, 1.37V and 1.39V and all of them are giving me errors during memtest. 1.31V had the fewest errors, but the amount doesn't really matter (especially when it's in triple figures) so the NorthBridge voltage does seem to be having an effect, but it's not the only thing that needs changing.

Oh, and these voltages are all when combined with the settings DerekT suggested.

Now the first stick I tested on its own went through and passed memtest with absolutely no problems at all in slot 1, so all was well.

I then put through the second stick on its own in slot 3, however I didn't get any errors, memtest simply hung. Everything stopped and froze, totally unresponsive, pressing escape didn't reboot and the time no longer progressed. I attempted to run the stick through slot 1, incase the motherboard could somehow be at fault, but got the same result.

 

So I took out the Overclocks, put all the settings back to default/auto and ran that same stick once again on its own, and it then passed memtest no problems.

 

 

Could I have a bad stick of RAM? It runs ok at 800MHz, but seems to have problems running at 1066MHz, which the RAM was advertised as 100% fully tested and compatible with, and the settings for it are even on the side of the stick itself. As I said, one stick passes memtest, the other causes it to freeze.

 

Oh, and just incase it makes any difference, all those tests were run without my Dominator Airflow fan mounted.

It would seem that you have a stick that does not make the 1066. I would look to RMA of the kit.

Hm, guess I'll get that RMA sorted tomorrow then.

 

Good thing I've got a 2GB (2x1GB) DDR2 kit that I can stick into the machine in the meantime....though that's gonna put a crimp on my gaming. Blah.

 

How long do Corsair RMA's normally take? Or does that depend on the vendor? (I bought mine from Overclockers.co.uk )

 

One other problem, I no longer have the original packaging. I had to destroy the blister pack to open it so binned it afterwards.

RMA can depend, both from the vendor or from Corsair as sometimes a backorder is necessary. Not often, but sometimes. Check with Overclockers.co.uk first since you are from the Isles. It will be faster with them. I still game fine with my 2GB machine as I wait for a new set of DRAM. And that's on my Vista64 machine. I'm building a P6T i7 and have moved my 2GB modules of DDR3 to that machine so I am sitting with 2 X 1024 in this box. Surprisingly I have found gaming still fine. :bigeyes:
