Spandex Posted January 9, 2009 Share Posted January 9, 2009 Hi, If anyone could help I would appreciate it...hands up to being a total n00b overclocker so usually I leave well alone, however my usual 'stick it all on auto dude' isn't going to cut it here. :) My problem is that I have almost no clue what my settings should be for my processor and RAM and everything I have tried results in fairly infrequent errors to frequent errors to nasty hard restarts. I just can't seem to make it happy. The processor is running default, I haven't changed any values there...yet :) I am on the latest BIOS and rather than continue to stab around in the dark, here I am. see I was told that I could run the RAM independantly at 1066Mhz and to buy 8500 to do so...I'm fully open to the fact that this motherboard doesn't do exactly what it says on the tin, and that my problems may not be the RAM but I have it on better authority than my own that it's 'just' a RAM timings issue. So if someone could advise the best settings or if it's patently obvious what is wrong, please show me the way as it would be much appreciated. Here are the pics of what I have currently. I have searched on this forum quite a bit but the advised settings don't seem to match what is available on my board or are perhaps labelled differently so I'm stuck... BIOS Pics (Activate to Precharge is actually set to 18 as per label on RAM) Thanks Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted January 9, 2009 Corsair Employees Share Posted January 9, 2009 Your memory voltage needs to be set to either 2.1v or 2.2v, look on the sticker on the heat spreader as it varies between revisions. Use the data sheet here to find your testing timings. Also, on this MOBO, if you are not stable at 1066, you will need to adjust the voltage on the memory controller.

Spandex Posted January 9, 2009 Author Share Posted January 9, 2009 ok thanks, I've tried those so I'll try the memory controller voltage then. Would that be the "DDR2 Controller REF Voltage" setting so then presumably I don't need to do anything to the Channel A and B settings are they only if you want to do them independently right? I also assume you mean up the voltage rather than back it off? Also in the last picture, how do I actually set the RAM to 1066, in the list of options I only have 1000,1111,1333.:confused: with it set to 5-5-5-15 and DRAM Frequency 1000 I get this on CPU-Z also should TRFC be set to 42??.... no idea where it got that from. Thanks for bearing with me.... Link to comment Share on other sites More sharing options...
DerekT Posted January 9, 2009 Share Posted January 9, 2009 I would flash to the latest BIOS. You have an error with your CPU FSB to DRAM Ratio if you are running with a FSB of 333. With a FSB of 333 you should be able to set to 1066. ie: Configure System Performance Settings Extreme Tweaker AI Tuning = Manual CPU Frequency = 333 DRAM Frequency = 1066Mhz PCI Express Frequency = 100Mhz PCI CLock Synchronization = 33Mhz Spread Spectrum = Disabled Over Voltage CPU Core Voltage = Auto FSB Termination Voltage = Auto NB VCore = 1.35v Memory Voltage = 2.1v DDR2 Channel A Ref Voltage = Auto DDR2 Channel B Ref Voltage = Auto SB Vcore (SATA, PCI-e) = Auto SB Chipset Voltage = Auto ASUS C.G.I. = Auto Static Read Control = Auto Configure DRAM by SPD = Disabled CAS# Latency = 5 RAS# to CAS# Delay = 5 RAS# Precharge = 5 RAS# Active to Precharge = 15 Write Recovery Time = Auto tRFC = 55 tRRD = Auto Rank Write to Read Delay = Auto Write to Precharge Delay = Auto Link to comment Share on other sites More sharing options...
Spandex Posted January 9, 2009 Author Share Posted January 9, 2009 Thanks Derek, BIOS error, hmm didn't even think of that. It was like that with the original BIOS too. I have the latest BIOS but just noticed there is a beta one which is considerably but I held off because it was a beta. So maybe I'll try that.

I have the latest BIOS but just noticed there is a beta one which is considerably but I held off because it was a beta. So maybe I'll try that. If it doesn't fix the issue, I would contact the motherboard manufacturer and see why the ratio of 333:533 (1333 [QDR]:1066 [DDR]) does not work.

Spandex Posted January 17, 2009 Author Share Posted January 17, 2009 still no joy, well it hasn't done a nasty hard reset yet but somethings still not right. @Derek, In your recommended setup you have "tRFC = 55" the maximum I can set is 42. I'll try what you suggest an ask ASUS, might be a painful wait for that one though. :(: Link to comment Share on other sites More sharing options...
DerekT Posted January 17, 2009 Share Posted January 17, 2009 Set your Northbridge to 1.4v and your trfc to "Auto" Download Memtest86+ V2.11 from--->Hereand extract the ISO image. Burn the ISO image to an CD-ROM disk. Download CPU-z from Here .Insert one stick of the 2GB module in the second slot closest to the CPU. Run Memtest for two full passes. Shut down and remove the stick. Place it in the fourth slot and test it again. Then insert the second stick in slot two and test it alone. Finally, insert one in slot two and one in slot four and retest. When assured of stable DRAM, then enter Windows and Run CPU-z and post screenshots of CPU-z's CPU, Memory and SPD tabs. Please post both modules SPD from the SPD drop down menu. Results? Link to comment Share on other sites More sharing options...
Spandex Posted February 22, 2009 Author Share Posted February 22, 2009 Ok, been a while but I got it stable or so I thought. I ran Memtest as you suggested Derek. with 1 stick in the single channel slot (slot 2) 1 stick fails immediately regardless of BIOS settings whereas the other stick handles pretty much everything you throw at it. When I ran them both in single channel it errors almost immediately. Anyway on default everything the same error apears on the 1 stick every time. In Dual Channel I get TEST1 PASS 0 FAIL ADD 000110a0b468 266.6MB GOOD 10A0B468 BAD 10A0F468 ERR BITS 00004000 Running them individually I get 1 stick always TEST2 PASS 0 FAIL ADD 00008505a28 133.3MB FAIL ADD 00008505a28 133.3MB GOOD 00000000 BAD 00004000 ERR BITS 00004000 So 1 stick is borked right? What do I need to do now? Thanks Link to comment Share on other sites More sharing options...
DerekT Posted February 22, 2009 Share Posted February 22, 2009 Did you test the stick in the same slot you tested the one that tested good? You need to isolate the slot from being a variable to the possible instability. If you have, then RAM GUY will deal with this. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted February 22, 2009 Corsair Employees Share Posted February 22, 2009 Last I remember, and it has been a while, users needed 1.45v+ to get DDR1000 or better on this chipset. However, if you have module that you cannot Memtest at all, please use the link in my signature below for TSX Express and begin your RMA. Link to comment Share on other sites More sharing options...
