First Custom FSX build

[G1000Pilot]

we are so close!!! Let me know if there are any specifics I should quadrupole check again at home later.


I have noticed that trees really take a hit on performance! I am curious to see how the OC helps this if at all.

[NickN]

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.

OK.. lets back up..

[NickN]

DO recheck the BIOS carefully... Load Line Calibration MUST be ENABLED in the BIOS or the Vcore of 1.35v will not be set correctly

Verify the entire BIOS list I posted

[NickN]

oh, and one other thing too..

I have seen some variations in Asus BIOS's for the BCLOCK math. It can be 133.33 as a base which will change the outcome of the memory speed on the 8x multiplier. So the deal is set the DRAM Frequency as close to 1600 as you can get without going over and then simply set UCLK Frequency to 2x that value.. it will follow through in the BIOS correctly at that point.

Use the same method for any BCLOCK test.. if you bump it up to 195 then by the 'formula math' the DRAM Frequency will be 1560 (8x195) and the UCLK Frequency will be 3120 (2x DRAM) however wilth the BIOS programmer they may have offset that a touch so use the highest DRAM F value without going over 1600 and then set UCLK to 2x that

understand?

[G1000Pilot]

ok got it. Hopefully I can get this puppy booting tonight with the OC.

Thanks Nick!

I set the UCLK slightly higher than the DRAM Freq! that was probably it! What do you think?

[G1000Pilot]

I set the UCLK slightly higher than double the DRAM Freq since it was closest to 1600! that was probably it! What do you think?

very possible.. and yes, that will do it

here is a i7 calulator that may help...

it works in MUTILPIERS instead of strait values which can be confusing but it WILL tell you if the DRAM and UCLK is out of sync. It will also give warnings as you input changes and click CALCULATE

to start you off.. input into the calculator

BCLOCK = 190
CPU MULT = 20
QPI MULT = 18 (note what happens if you input 24 instead)
UCLK MULT = 16 (note what happens if you use 12 instead)
MEM MULT = 8 (will always be 8 for you)

you will see the results in the bottom boxes and they will direct your settings in the BIOS

Nick we are in business!

I am running the first test at 3.8Ghz and so far we are staying under 80, we shall see!

p.s. I am writing from a different computer

[NickN]

LOL

we have ignition!

When you finally get the highest CPU speed/lowest CPU voltage locked down use CPUz and post the CPU and Memory tabs for me

and remember.. sometimes OCCT may pass but we may still find a bit of instability in the system with FSX running so even though you may have found, in example, 1.35v passed in OCCT for 4GHz it may still be a touch low for high load 3D

your goal right now is to find @ 3.8Ghz the LOWEST CPU Voltage it will run stable and remain under 80c.. which can be anywhere from 1.25-1.35 @ 3.8

once you find that, note it to come back to if needed, then bump BCLOCK up to 200 and reset the DRAM F to 1600 and UNCK to 3200 with a successfull boot your goal is the same.. find the LOWEST CPU Voltage stable @ 4GHz and remain under 80c... which is usually between 1.32 and 1.42

I am butting up against 80 at 3.8, but i will try for 4 at the end of this test and keep the 1.35V and see what happens! I will post the tabs upon final settings

OK now remember.. 1.35 may not be needed for 3.8. You may be stable at 1.28 @ 3.8!

ok sounds good. How will I know if she is not stable? No boot? Weird Screens?

Oh, dont worry, you will know

Do you have speakers on?

1080 is actually lower resolution than FSX wants to run and I have heard of people doing that and it works however you may need do a bit of settings work for it to run right... the drivers need to be set up for HDTV display

Ive been running my 8800GTX into my Westinghouse TV for a year now.  With Vista x32 I had some issues with it.  It wouldnt take in some resolutions, blurries in Windows and FSX and such.  

Vista x64 seems to fire the TV up with no problems.  FSX runs and looks great as set up by the Nick numbers.  All resolutions in windows work with no problems.  Why might Vista x64 behave better for the TV as a monitor and Vista x32 not?
