ok great!

also, i would like to review my bios settings once defrags are done. I will let you know when all the tuning and what not is done.

we should chat about the bufferpools too!

I know you have DX10.. but you will not be using DX10 enabled in FSX

Wanny know why?

1. Nhancer does not work with DX10
2. DX10 Vsync is broken
3. DX10 AA is enabled through FSX graphic settings only and is not the full AA the video card can do
4. DX10 is a preview only and there are bugs such as disappearing taxi guides, flickering taxiways, other annoying problems not to mention even more problems with some addons than SP2

You will leave the DX10 preview box in FSX unchecked and will be setting up FSX in DX9 mode only. If after all is said and done you wish to run DX10 mode then you will enable AA in FSX, set filtering to Anisotropic and there will be no Nhancer control

Bufferpoools is something we work with last during tuning. Typically for a 1GB card on a system that shows no issues with sound crackle under hiigh autogen slider use the value will be somewhere between 100000000 and 200000000 but that is not always the case. That is tested flying over large amounts of autogen trees and is something we tune after everything else has been tuned

In some cases its not used at all

Are you telling me you are ready to clock now?

If so I can post the BIOS values and the process to verify


If you think GEX USCAN is good.. wait till you see Europe. We have raised the bar on texture design with it 10 fold

FPS locked or unlimited can end up changed mid-flight. For you I would say lock it at 28 but be aware there can be places like a busy hub setting it to UNLIMITED may be better and you may need to drop Scenery Complexity a notch if its a really busy hub in a large city.. that is a call you need to make as you test


Alright.. Clocking i7 is the easiest processor to deal with. Unlike clocking in the past where there were about 10 variables that had to be addressed with i7 there is essentially 1 base set of values with (usually) 2 of them being variables in a stable clock. Those are CPU Voltage and QPI/DRAM Voltage. The user must find the highest stable speed with the lowest CPU Voltage which remains under 80c in temp in the 1hr OCCT stress test. That is problematical to

1. the heat sink and its installation
2. the towers ability to allow the right airflow
3. the ambient temp environment where the tower is located

Even with a perfect install and airflow design, all three present variables over time with the buildup of dust and changes in the environment.

So.. to clock i7 we start with a list of BIOS settings that should be the same for any clocking situation and then you must find the lowest stable CPU Voltage at the highest CPU speed.. 4GHz being the top end.

With a i7 920/940 CPU speed is increased by using the setting BCLOCK because the CPU multiplier is locked (with the exception of 2 options).

BCLOCK base is 133

The multiplier or CPU RATIO for 940 will be set to 20x

BCLOCK 133 x CPU RATIO 20 = 2660

When we clock, we raise BCLOCK so in example, for a 3.8GHz clock we run:

BCLOCK 190 x CPU RATIO 20 = 3800

for 4GHz it would be

BCLOCK 200 x CPU RATIO 20 = 4000

Simple?  OK, thats just getting the ball rolling. Assuming you are into a stable boot with your tested clock setting then we check our system to verify our BIOS is correct using CPUz. The CPU and MEMORY tabs will display the information we wish to verify..

It should look like this with a 4GHz clock:

But DO keep in mind the memory SPEED and timing will be based on your installed memory.. in your case that is 8-8-8-24 1T and not what is shown in the link above.


Here is your BIOS.. I am going to start you off at 3.8Ghz and not 4Ghz so you can confirm stability and temp before going for the highest clock   OK?

now.. Assuming you have booted into Windows and have verified in CPUz the CPU speed, Bus Speed (BCLOCK), Memory Speed and Timing and the NB Frequency (UCLK Frequency) then its time to test for stability and temps

Start REALTEMP and leave it on the desktop (you should have already set REALTEMP and OCCT up as listed in the above post)

Start OCCT.. the first test is the 1hr CPU automatic test.. its as simple as starting and letting it run for 1hr. You can observe the temp on the RealTemp interface which will also show you the MIN and MAX for the session and if you set OCCT to fail at 80c that test will stop automatically if you exceed that.

IF you pass OCCT and you are well under 80c then you can try for 4GHz by raising BCLOCK however that MAY or MAY NOT require you raise the CPU VOLTAGE too. this is where YOU must make the call. I would start at the same voltage 3.8GHz passed and if a retest with OCCT FAILS and the proc remained below 80c then its unstable and needs more CPU VOLTAGE. The MAX CPU Voltage I consider safe for a inexperienced user is 1.42v

Now.. this is the part you must do on your own.. Find the highest CPU SPEED running the LOWEST CPU VOLTAGE, stable, and remain under 80c. Just because you PASS the test does not mean you are finished! At that point you need to try a slightly LOWER CPU VOLTAGE till you find the LOWEST STABLE value. In example, you may find your highest stable speed under 80c is 3.8Ghz @ 1.32v instead of 1.35 or you may find you can hit 4GHz ,80c and run 1.34v stable.. you must find those values.

That can take some time to do and be patient. Let those 1hr tests run all the way to the end. You can also access GRAPHS of the temp and speed as shown in this post with OCCT after the tests complete

http://www.simforums.com/forums/forum_posts.asp?TID=30486&PID=174471#174471

that graph shows a perfect run @ 4Ghz with temps remaining just under 80c in a successful test on a 920


So that is your mission now

If you destroy your processor and system the secretary will disembow any knowledge of your actions...

Once you find that highest stable/safe speed you can then start flying again and at that point we may need to look at a few other items in FSX config/settings



This thread will self destruct in 10 seconds.. good luck

haha copy that!

So when you say i adjust the voltage/cpu speed that is after it passes the 1hour test right? Then I just creep the voltage down? This should be really easy on the Asus board since I do not have to reboot into bios!

This will be tonight's project  

Either way I will post all progress for review.

Nick,

It will not let me boot. My UCLK and DRAM are set values that do not match exactly what you told me to put in. It is 1534 and 3247 i believe. I just get a blank black screen, restart it says OC failure and tells me to go back and change settings.

correct, the only thing was the UCLK/DRAM where the default values that I could select were not the exact numbers.

Looking back on the CPU mult of "20X" I put in 20 and left out the X. Other than that I went through it three times. I can try again tonight! I am sure it is something on my end that I am not putting in right.
