purity Posted October 20, 2008 Share Posted October 20, 2008 Dear RamGuy, I never have stability problem or BSOD, but when I check my system with CPU-Z yesterday, I was surprise to see that my system DRAM speed is so low. The Timings on CPU-Z show : DRAM Freq: 592.1Mhz FSB:DRAM 1:2 CL : 7.0 Clocks tRCD: 7 Clocks tRP : 7 Clocks tRAS: 20 Clocks Command Rate : 2T on the other page called SPD, it show information per slot. at SLOT1 (all other slot look exactly the same), it said Module Size 1024MB Max Bandwidth PC3-8500F (533Mhz) ??? I tought mine will be at least 1066Mhz since that is the FSB speed of Q6600??? manufacturer: Corsair (of course :) ) Part number CM3X1024-1333C9DHX then the timings table... and I notice at the bottom the Voltage is 1.5Volts. for the CPU, the clocks on Core#0: Core Speed (keep changing) from 1776.3Mhz to 2664.7Mhz Multiplier x6.0 Bus Speed 296.0 Mhz ??? Rated FSB 1184.2 Mhz ??? My questions are: a. I think my system is not optimize to the full capability available... since I leave all the BIOS setting on Auto except some setting where I put "stronger" I forget which one is that, and another setting I put "High performace" or something like that... b. I do not mind reasonable Overclocking if needed to bring the system to it's best/optimal performance/stability c. I have the latest 1406 bios from ASUS and all latest update from Microsoft.Well I never experience any issue with older bios ... but I suspect that because my system is so UNDERTUNE. d. Would you mind giving me spec I need to change on the BIOS to bring my system to it's proper speed? I think my Memory would not be able to run at 1333 Mhz since my Q6600 still at 1066FSB right ? but at least my Memory should run at 1066MHZ and not at lousy 592.1Mhz??? again I am newbie, please tell me which option on the bios to choose. I am not really familiar which menu correspond to latency etc etc... When I got early lesson from you, I am sure I can learn more optimizing by my self later on.But I need to get the most basic lesson on this one... oh yeah, one last thing, I change the jumper on the Motherboard, so it allow for higher voltage(following the owner manual book)... but I did not know how to actually set up the voltage in the bios in the first place.... Thank you for your kind help in this matter Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted October 20, 2008 Corsair Employees Share Posted October 20, 2008 With 4 modules I would suggest setting the memory frequency at DDR1066 and set the memory Voltage to 1.7-1.90 Volts and set the NB/MCH/SPP Voltage to +.2 Volts as well and test the system with http://www.memtest.org. In addition, with some MB's (Mostly ASUS) you have to disable legacy USB in the bios when running any memory test. Link to comment Share on other sites More sharing options...
DerekT Posted October 21, 2008 Share Posted October 21, 2008 You are missing the DDR aspect. 533Mhz X 2 = 1066Mhz. The below graphic shows the DRAM running at 533 X 2 = 1066Mhz, just as yours. http://www.bcchardware.com/gallery/albums/ST1866DDR3/1066mem.jpg For the CPU speed, you are running with Intel SpeedStep which lowers the multiplier when the power is not needed and raises it when necessary.

Wired Posted October 21, 2008 Share Posted October 21, 2008 Curious: Why Server 2008? Running it as an actual server, or your personal system? Link to comment Share on other sites More sharing options...
purity Posted October 21, 2008 Author Share Posted October 21, 2008 Hello, I am using Server 2008, as I feel it is a more stable OS compare to Vista SP1. I use this as personal system.(no server service activated). Oh, yes, I also want to Thanks DerekT and The RAM Guy, for the replies.Help me understand more about OC. I never do this kind of OC before, my last PC is a 478socket P4P8X, and the OC setting on that board is a fix 5% or 10% OverClock... so this ASUS board with all the options really confuse me... I also find interesting (and Helpful) post from DerekT http://www.asktheramguy.com/forums/showthread.php?t=72375&highlight=P5Q3 and I use this setting as first try. It ran great. then I try to modify a little with AI clock Twister = stronger (instead of auto) DRAM Voltage = 1.74volts (instead of 1.7volts) NB Voltage = 1.32volts (instead of 1.28volts) Load Line Calibration = Enabled (instead of disabled) CPU Margin Enhancement = Performance (instead of Optimized) So far so good, although I have not done any memory test run... Right now my Core Temp reading from Real Temp 2.7 is around 45Celcius at idle, and only hit 60Celcius when I try to open 10windows of FireFox at once I still use stock CPU cooler, but my case is CoolerMaster Centurion 590, and I put 7 unit of 12cm case fan on it, so it helped. do you think at 45Celcius Idle, I need to change the CPU Cooler? at CPU-Z, my Core speed varied from 2003.6Mhz to 3005.5Mhz (I think it is the speedstep function, but I am very sure, I already turn SpeedStep function off on the BIOS, how come this function is still on ?)The multiplier also varied from x6 to x9 The CPU Core Voltage is at 1.424Volts (is this TOO HIGH? please help me) the Bus Speed is 333.9Mhz Rated FSB 1335.9Mhz for the Memory, DRAM Freq now at 667.9Mhz FSB:DRAM = 1:2 at 9;9;9;24 clocks On the SPD menu, I notice the voltage are all the same only 1.5volts. why it is only 1.5volts, I tought I set it at 1.74volts ? I also saw, on some other people configuration that their FSB:DRAM = 2:3 or other combination. How can you set this FSB:DRAM value ? Oh yeah, One more strange thing that I notice. Before I do this Overclocking, and the setting is all STANDARD/AUTO with FSB at only 1066Mhz following Q6600 standard spec, My PC run instantly when I push power button. But right now after this Overclock, everytime I turn off the PC, and disconnect the electric plug from the wall socket, and then plug it back and turn on the PC, The PC would start right away, and then 2 or 3 seconds later turn off by it self... then 3 seconds later turn back on by itself, then it boot everything normally. but if turn off the PC and NOT disconnect the electric plug from the wall socket (inside the led on the board is still on meaning electric current is still running even though the PC is off), and then I turn on the PC, this PC will start right away and no turn off turn on cycle... why is it like that ? because of that, now I never unplug the electric plug from the wall socket anymore.But then I can see the LED inside the casing is still on.Will this shortened the live of my Power Supply and Motherboard, since it still have electricity all the time 24/7 even though I did not use it ? Pardon my English, I am from Indonesia :) Thank you. Link to comment Share on other sites More sharing options...

I use this as personal system.(no server service activated).So you paid for a Server OS for stability? Why not just pick up Vista for less and downgrade it (I think you still can), or one of the few remaining copies of XP that are floating in some stores still?

DerekT Posted October 21, 2008 Share Posted October 21, 2008 do you think at 45Celcius Idle, I need to change the CPU Cooler? You are at the cusp. It is, in my estimation, dependent on how you use the system. If you run it 24/7, then I would purchase something like an Arctic Cooler Freezer 7. Low priced and works quite well, and you do not have to remove the board. I already turn SpeedStep function off on the BIOS, how come this function is still on ?)The multiplier also varied from x6 to x9 Enter the Advanced Section in your BIOS. Disable both C1E Support and Intel SpeedStep Technology. The CPU Core Voltage is at 1.424Volts (is this TOO HIGH? please help me) Not for a Q6600. However, you may wish to test for stability and lower it to see if it will run stable at a lower voltage. On the SPD menu, I notice the voltage are all the same only 1.5volts. why it is only 1.5volts, I tought I set it at 1.74volts ? SPD = Serial Presence Detect and is information coded at the Module Level. It does not show what your system is currently set to, rather it shows the default settings for that DRAM in JEDEC. I also saw, on some other people configuration that their FSB:DRAM = 2:3 or other combination. How can you set this FSB:DRAM value ? This is a function of the CPU : DRAM ratio and can be set through the Strapping (ASUS). However, your DRAM is running at twice the speed of the CPU FSB which is quite good. You will drop it when you overclock the CPU. I would NOT unplug the computer from the wall after you turn it off. This is not a good thing to do to the system. I advise you to use standby mode and allow for the system to run in standby mode. The amount of power used in Standby Mode is very minimal and plugging the power plug in and out can lead to long term issues. The turning off and on of the system after you press the power is a safety setup of the Core 2 processor. Anytime the power to the system is completely removed or an overclock instability is found, blue screen, etc. the system will start up, shut down, test itself, and restart if no issue is found.

purity Posted November 2, 2008 Author Share Posted November 2, 2008 Hello, Basically, I want to know about whether CORSAIR Dominator FAN, BLOWING air or SUCKING air ? Last week I change my Intel standard CPU Heat Sink Fan with Scythe Zipang, and I notice my CPU run much cooler now. I also take out the standard Intel CPU Fan from the HeatSink and put it on top of the Corsair Memory Heatsink, in fact the plactic clip on the Fan, fit perfectly into the groove in the Corsair Memory Heatsink.Then I tied the housing of the fan to the housing of the Scythe Fan and to the ASUS standard SouthBridge Cooling Pipe. Later I also add an 8cm fan to cool part of the Corsair Heatsink that is not covered by the Intel CPU Fan... One question... is the Optional Corsair Dominator Fan BLOWING the air TOWARD the Corsair Memory Heatsink or SUCKING the air FROM the Corsair Memory Heatsink ? the reason I ask, because with the Intel CPU fan and the other 8cm fan that I use now to cool the memory, they are both BLOWING air TOWARD the Corsair... is it ok to blow air toward the memory heatsink or is it better to SUCK the air FROM the memory heatsink? Thank you... Link to comment Share on other sites More sharing options...
purity Posted November 3, 2008 Author Share Posted November 3, 2008 I also increased the Level of Overclocking since I have Scythe Zipang Heat Sink Cooler now :) My Intel Q6600 now run at 3.21Ghz speed and the FSB is now at 1600Mhz Using Real Temp, the Core Temperature range from 28 Celcius to 32Celcius at Idle in fact right now the Idle Core Temp is: Core 1: 32Celcius Core 2: 31Celcius Core 3: 28Celcius Cord 4: 30Celcius I have two 12cm front Intake fans, two 12cm side intake fans, one 12cm rear exhaust fans, two 12cm top exhaust fans one 6cm behind motherboard right below CPU mounting intake fans and of course the Scythe Zipang 14cm fan, the original Intel CPU heat sink fan now cooling the Memory together with extra 8cm fan, and the ASUS small North Bridge fan but now used to exhaust air through rear of casing. and the last fan is at the Leadtek WinFast 8800GTS 512Mb fan... The Enlight BlackSilver PowerSupply Fan doesn't count since it is intake from the bottom of the casing and exhaust right away to rear of Casing,so it never interfere with inside casing airflow. Yes my PC is a bit noisy :) So far the computer run very very STABLE,... I never run any memory test... because I never experience any crash or any error... Is this OK ? I hope it would not break my PC Motherboard/CPU/Memory with this kind of Overclocking... anyway, Below is my BIOS Setting: AI Overclock Tweaker Configure Advanced CPU Settings CPU Ratio Setting = 8 C1E Support = Disabled Configure System Performance Settings Ai OVerclocking Tuner = Manual CPU Ratio Setting = 8 FSB Frequency = 400 PCIE Frequency = 101 (I use 101 instead of 100) FSB Strap to North Bridge = 400 DRAM Frequency = DDR3 - 1600Mhz Dram CLK Skew on Channel A1 = Auto Dram CLK Skew on Channel A2 = Auto Dram CLK Skew on Channel B1 = Auto Dram CLK Skew on Channel B2 = Auto Dram TIming COntrol = Manual Primary Information CAS# Latency = 9 DRAM RAS# to CAS #Delay = 9 DRAM RAS# Precharge = 9 DRAM RAS# Activate to Precharge = 24 RAS# to RAS# Delay = Auto Row Refresh Cycle Time = Auto Write Recovery Time = Auto Read to Precharge Time = Auto Secondary Information Read to Write Delay (S/D) = Auto Write to Read Delay (S) = Auto Write to Read Delay (D) = Auto Read to Read Delay (S) = Auto Read to Read Delay (D) = Auto Write to Write Delay (S) = Auto Write to Write Delay (D) = Auto Third Information WRITE to PRE delay = Auto READ to PRE delay = Auto PRE to PRE delay = Auto ALL PRE to ACT delay = Auto ALL PRE to RED Delay = Auto DRAM Static Read Control = Enabled DRAM Dynamic Write Control = Disabled DRAM Read Training = Disabled DRAM Write Training = Disabled MEM.

DerekT Posted November 3, 2008 Share Posted November 3, 2008 the reason I ask, because with the Intel CPU fan and the other 8cm fan that I use now to cool the memory, they are both BLOWING air TOWARD the Corsair... is it ok to blow air toward the memory heatsink or is it better to SUCK the air FROM the memory heatsink? Blowing down on the component is usually the best method. Sucking up will create a vacuum effect and not cool the DRAM as well. If your system is running fine with never a crash or blue-screen, then certainly stability testing is optional. :): Link to comment Share on other sites More sharing options...
purity Posted November 3, 2008 Author Share Posted November 3, 2008 Thanks Derek, but just curious do you know whether the Corsair Dominator FAN is blowing air or sucking air ? just by looking at the picture of it, my guess is that it is also blowing down air... but when I look at Corsair brochure on how the memory heatsink works... it show the heat release going up from the memory heatsink...so that is why I worry that blowing down air on it would make the heat goes back into/inside the heatsink and actually make it hot... ??? oh yes, out of curiosity, I just run the memtest and only after 64% past it show more then 200 errors... but since my computer is stable and never have BSOD, I think I am just going to leave my setting as it is... but please tell me you are SURE that even with more then 200errors after only 64% pass, it will not destroy my Processor/Memory/Motherboard (north and south bridge)... in the long run... if I kept this setting... Thank you again, Best regards, me Link to comment Share on other sites More sharing options...

You are running with 4 sticks of 1333Mhz DRAM at 1600Mhz. I would advise that you drop your DRAM speed to 1066Mhz when you populate all four DRAM slots with 1333Mhz DRAM. It's your DRAM, do what you want, but I would not do this to my machine. With regards to the air fan blowing down. All the Corsair Fans I have seen blow the air down. Check them out. Take it off the DRAM and check. Those are DDR3 modules and running at 1333Mhz and will not be running hot at any rate, so up or down is a moot point really. Now you should be dropping the speed of the DRAM down since you are populating with four DRAM slots. You could very likely damage the motherboard memory controller. Check this site. Do a search for 4 sticks or 4 modules, or 4 X 1GB, or 4 X 2GB. Go to any DRAM site and do the same search. Please research this thread: http://www.houseofhelp.com/v3/showthread.php?t=64360&highlight=Unpredictable+results+QUAD2X4096+Gigabyte+X38-DS5 The issue is the memory controller and a population of all four banks at the full speed of a two bank run. This issue is across the board with both Nvidia and Intel chipset based boards, DDR, DDR2 and DDR3. Keep in mind that often issues arise in the longer term. The issues seldom damage the DRAM. They damage the on motherboard memory controller which has a harder time keeping up with the demands of a four DRAM slot population being run as fast as a two DRAM slot population. Those who want to be secure in their system either purchase a single kit of the DRAM capacity that the four singles have or they move to a higher bandwidth DRAM and drop the bandwidth. I also advise it as I have personally seen the issues that can and often do arise with a four DRAM slot population running at the full speed of a single kit speed. I personally advise for a two stick solution as it is far gentler to the motherboard memory controller. There is no guarantee that you will not experience damaging effects if you continue to run a four DRAM slot population at the full speed of a two DRAM slot population. As well, there is NO guarantee on anything when you overclock. If your system has issues in the future from your heavy overclock of an overloaded Memory Controller, then you will be in the RMA process for quite some time. I wouldn't do it but there are some people who do not listen to reason and do what they want. Good luck with YOUR system and YOUR settings.

purity Posted November 3, 2008 Author Share Posted November 3, 2008 Hi Derek, thank you for your information, actually I had read about this problem a while ago, it is just that when I am buying this memory module, they ran out of 2x2GB kit (remember I am in Indonesia :) ) so I am forced to buy this 4x1GB kit... too bad... perhaps 3 months from today, I would sell this memory and trade up to 2x2GB kit of 1600Mhz memory module... until then, I think I am going to slow down my FSB speed per your suggestion... Thank you again, Best regards, Me Link to comment Share on other sites More sharing options...

I think you are very smart to do this. In time the prices of the 1600Mhz DRAM will drop as well. Don't mind my strong response. :): I wanted you to see how dangerous this could be in the longer term.
