LOL

Well Vic.. your learning how to deal with a tough clock.. we have not worked with Skew yet, only GTL so its not over

But I do want you to remember, you purchased good DDR3 1600 memory and not DDR3 1800 so that is a definite factor in this

I wil fire off some emails this week and see if i can get info about the changes in the BIOS since i last worked with it some months back however it is very possible the 1600 memory you selected is simply not suited for a CPU/memory intensive application like FSX on the x48 platform at 1800

I would let it go because I know he is going to tell you those sticks are 1600 and the tests he runs are for benchmarking

Yep.. we are looking for the 14.7 to 1 ratio of air to fuel with an increase on the MP and adjust the waste gate on the back side.. its a process and one that is actually very simple with the right parts out of the box.


Right now we know

450x9

333 STRAP

8-8-8-24 @ 1.9v DDR3 1800

PL 08

1.28 vcore  1.52 NB

1.25VTT

2T (and 1T

GTL -40

gets us a stable OCCT, at least that is what I read. The only problem here is FSX

I dont know if you tried PL 7 in OCCT at 1/2T and it passed


So the next step will be to set that back up and start wroking with CPU/NB SKEW and possibly a bit of DDR Skew

I cant do it right now but will post back here with values to start

This part of fine tuning is really a PITA and it all goes back to the memory chips being used.

Interesting - thought I'd play a bit while waiting for your numbers so I researched the CPU and NB skew a bit on the Asus website. Basically got a range of 300 - 500 CPU and 100-200 NB. Given that the settings are in 100ps increments.

With the settings as the original mushkin 450x9 I tried various combinations of those settings.

well, the last one - 500 & 100 reset the cmos by itself.

The others were strange - it was like my graphics card went berserk! In FSX I got flashing polygons, jumbled mishmash of colors in the sky and then it settled down.

Decided since I really had no clue, it might be best to stop.

Would those ranges apply if I used the settings we came up with at 450x9? oh, the ranges in the BIOS go from Auto up to 1500ps delay in 100 ps increments for both CPU & NB

The education continues..................

however - ran memtest86 over 2 hours with no errors but tried to run prime95 blend test - system reboot in a little over 2 hours. Tried raising vcore from 1.28750 through 1.3800 in several steps -  end result was system reboots - some almost instant.

Puzzled!

back to 400x9 & 1600 

Hi Nick - noticed your diminished presence - figured you had your head stuck in Gex Europe.

I'm through playing but I did find out something interesting, I think -

memtest8 for over 2 hours with no errors on the memory at 1800 8-8-8-24-1N should indicate that the memory can handle the load, correct?

And running the 450x9 Prime95 with small FFT's for over 9 hours should indicate that the CPU can handle it.

BUT, put them together and - zap! reboot time. That should indicate something.

Altho a little frustrating, I'm actually having fun - I like challenges and puzzled and I am very patient. LOL, the very first time I tried to clock the Q6600 I increased the FSB by 1 each time and tested. Took a LONG time.

Anyhow, I know you're busy and I'm not jumping up and down in a frenzy so in your own time - all is appreciated.

From the number of reads of this thread, I hope a lot of folks are getting as much out of my issues as I am.

Later....

WHAT????? You have a life outside of here???

Unheard of - stop it at once!  

not much of a seaman but I understand yachts can eat up a lot of time. Now the Dino - for me that would be a labor of love. Had a couple of Jag XKE's that I was always tinkering with. Lot of folks in my neighborhood thought a Jag came with legs sticking out from under the bonnet. 

Now it's just computers and woodworking that take up my time.

Those of us who have owned off-shore yacht racers wouldn't call that thing of Nicks a yacht.  Gin palace would  be a better description.  But let me tell you, motor or sail, that any boat is a hole in the water into which you throw money.

Nick I'll know tomorrow I hope how an i7 940 pairs up with an 8800GTX.  If it doesn't it means scratching the bottom of the savings tin to see if I can find enough for a GTX 980 - a minimun of $750 in Australia!

Maybe boats are cheaper after all, certainly the depreciation rate is about the same!
