[Anubi]

Ghost,
Here's the OC steps I'd recommend to anyone trying to overclock their system. First lets find the FSB limitation.

Go to memory page, on Performance Memory Profiles select automatic. Hit enter, then select Manual. This will get you back to a know default state.

Set Reference Frequency to Default
Memory Frequency to 800

On CPU Page
CPu Voltage Override Default
CPu Voltage Offset Disable
Enhanced Power Slope Enable
FSB Voltage 1.2
MCH Voltage 1.25

Processor Multiplier set to 6
Host Clock Frequency set to 266, this is default for your CPU.

Next try out these settings and make sure it boots. It should, cause it's all really conservative. Then start raising your Host Clock Frequency until you find the point it doesn't boot anymore. You should run some stress tests for a few minutes to ensure it's stable.

Now you know your maximum stable FSB speed at default voltage. You can try increasing the FSB Voltage, the MCH Voltage. And pushing the Host Clock Frequency higher. You probably won't see much for gains above FSB voltage ~1.4 and MCH voltage ~1.5. And you want to run the voltage as low as you can to hit the speed you want to hit.

Next find the max CPU Core speed you can run. Keep the Host Clock Frequency you just found and increase the Processor multiplier until the system won't boot anymore. If it boots at 7 for example and not at 8. Set 8, then drop the Host Clock Frequency down say, 50 MHz. Try booting again. Now you can move the Host Clock Frequency up and down until you find the point the max CPU Core speed it will boot at. The Processor page in BIOS will show you can actual Processor Speed. Next try raising the CPU Voltage Override. Before you change it from default note what the Current Processor Voltage is as shown on the bottom of the screen. Raise the Voltage a bit and see if you can raise the Host Clock Frequency.

As you can see, it will take a while to really tune your system and find all the limits. Once you've finished all the steps above you should know your max CPU Speed and max FSB Speed.

Next will be memory, but I'm getting tired of writing at the moment

what is orthos and how do i obtain and use it?.

is it a windows or bios program

how does it differ from memtest86??????

Orthos is a windows program that runs two instances of Prime95. It stresses your CPU and memory and will report if it has errors. It's a good stability test. You should be able to find it with google.

Ok, I found something weird, I think it might be a bug in 1521 BIOS.

I'm using an E8400, it has a 1333 FSB by default. Whenever I select Referency Frequency of 400, it hangs and I can't boot. Even if I load all defaults and just change that one thing. It should work...

Anyone know a BIOS version that this works? Changing the reference frequency to be higher than the default? This might also be causing some of Ghost's headaches.

Ghost,
Then start raising your Host Clock Frequency until you find the point it doesn't boot anymore.

IM TRYING 300MHZ AT THE MOMENT

300 Mhz Booted

Onto 333mhz !

333 BOOTED

ONTO 400

AFTER SEVERAL ATTEMPS 400 FINALLY BOOTED

ONTO 433

i have an E8400 and i've been using 400/1333 reference frequencies since i got the board. it works fine for me. i use those settings because i can't run a 1:2 ratio with my FSB this high and 400/1333 gives me an extra 60 MHz on my memory than 333/1066 would.

433 Mhz Failed

Even if the resulting frequency is acceptable, not all combinations of reference and memory frequency will work. Same with XBX, XBX2, and X48 boards.

In this case it may be that the 400 strap sets too loose internal timings in the X38.

[RRGHOST2006]

400 Mhz Is My Limit
After 5 Tries I Finally Got Back Into Bios From Maintenance
Mode After Setting My 433 Back To 400

Wow Now Instead Of Going To Windows Using Orthos I Accidently
Went Back Into Bios Now I Cant Post So I Can Get To Windows

I Really Dispise This Board Im Starting To Think It Hates Me

I Now Realize The Only Way To Get Back To My 400mhz

Is By Hitting The Power Swich On The Psu And Waiting About 1 Min

Than Booting Again

MEMTEST RUNNING ABOUT 4 MIN USING TEST 7
ALL TESTS PASS

NOW IM GOING TO TRY ORTHOS TORTURE TEST
I WILL REPORT ALL INFO AS I GO

I REALLY REALLY APPRECIATE OF OF YOUR HELP

THANK YOU SO MUCH

How do i know if orthos has failed as of right now

it is running

TEST 3, 4000 lucas-lehmer iterations of M19374367 Using 1024K FFT length

[Sean-E-Boy]

Sean,
Ya, the mutliplier will still drop when idle even with EIST disabled because of C1E. There isn't a BIOS setup option to disasble C1E. GTJ has posted about this before and I think he has mentioned a driver you can load if you really want to disable it.

ok, got that, but does EIST being disabled prevent me from setting my multi lower than 10? like i said, with it at 9 CPUz still shows it at 10 under load and then down to 6 at idle.

How do i know if orthos has failed as of right now

you'll know, it is very obvious.

[RRGHOST2006]

now its at test 4 ??

now test 5

by the way sean i tried your method and as you can read from my previous posts
i failed horribly

failing result = no post

anytime i tried to up the memory frequency i would not be able to post
but i did pass all tests using just the other stick of ram that into which i never tested by itself
with memtest86


onto test 6 of orthos

self test 1024k at 400mhz passed

[Sean-E-Boy]

do you have 2 windows of orthos open or just 1?

[RRGHOST2006]

Just 1 Sean

Should I Open Another?

[Sean-E-Boy]

yes, but you are going to want to stop the first 1.

after that, open another window and then go into the task manager, processes tab and find the 2 instances of orthos. right click on the first and choose set afinity and select cpus 0 and 1, and on the other orthos.exe, do the same thing but this time select cpus 2 and 3.

now click start on both windows.

[RRGHOST2006]

SEAN!!

Im Only Finding 1 Prime95 In Task Manager

[Sean-E-Boy]

oh, i thought you were using orthos

[RRGHOST2006]

Ok I Figured It Out

I Messed That Up

I Tried To Do That Open It In 2 Windows And It Crashed Or Something?

Unable To Open Log File????

Execution Halted

Are You Saying Run 1 At A Time

1 For Cpu 0 & 1

Then Run 1 For Cpu 2& 3
Not Both At Once Right????

[Sean-E-Boy]

i dont think that it works right with Prime, but with Orthos

Are You Saying Run 1 At A Time

1 For Cpu 0 & 1

Then Run 1 For Cpu 2& 3
Not Both At Once Right????

yes

[Anubi]

If you get the later versions of Prime95 it can run multiple threads. I think 25.6 is the latest version.

[RRGHOST2006]

Sean You Are The Man Thanks Dude

Im New To All This I Thought I Was Running Orthos
But Infact I Was Running Prime95

I Am Now Doing What You Said

Thanks Man,

ANUBI YOUR BACK HUH???
IM STILL WORKING ON WHAT YOU SAID
I THINK IT IS SAFE TO SAY

400 MHZ is my sweet spot for now running all on default
which is what i do recall a ways back
GTJ stated back before i was even a member .

anubi will you please type the ram side of getting a system stable
i will get to it as soon as i get home from work tomorrow
or tonight which ever comes first!!!!

thanks for all your help man

[Anubi]

ok, got that, but does EIST being disabled prevent me from setting my multi lower than 10? like i said, with it at 9 CPUz still shows it at 10 under load and then down to 6 at idle.

I didn't do a lot of checking, but I've been working through a setup. When I had the multi set for 8 and EIST enabled. In Windows CPUz showed 6 at idle, then 8 under load. When I disabled EIST, in windows CPUz showed 6 at idle and 9 underload which is the max for my E8400.

[RRGHOST2006]

what does WARNING : Affinity Mask: Process : 0xC Sys : 0xF

WHAT DOES THAT MEAN?????

ANYBODY?????

Well Both Self-tests Passed At 400mhz

Using Core 0-1
And Core 2-3

But Its Still Being A Real Pain To Boot Again
At 400 Mhz It Acts Like It Does Not Want To Boot

I Have To Mess With It For A While To Get It To Boot

[Sean-E-Boy]

all the warning for affinity mask means is that you are contrrolling which cpu cores are being used for the process.

[RRGHOST2006]

Ok Well ..

Please Read Above Message

I Think Im Where I Need To Be Anubi

Can You Post The Process For Ram As Soon As You Can ????

Please ???

[Anubi]

Ok, if you know the max speed your CPU and FSB can run next you'll want to find the max memory speed. I don't have a system handy to look at the BIOS page right now so I'm going from memory on the names. This is where it starts getting more complicated but I'll give it a try writting up some steps.

I'd start by dropping your CPU multiplier down to 6 (maybe not necessary, but it helps to eliminate variables) and your host clock frequency down to 333.

I think you mentioned there was a Profile 1 listed for your memory that ran at 1333. I'd start by selecting that, then selecting manual so your starting out with the profile settings.

Reference Frequency is also sometimes called the bus select strap, BSEL, or just straps. Normally the CPU signals this to the MCH, your Q6600 signals 266 to the MCH so it knows what clock is coming in and what ratio to set to get the right memory speed. The Reference Frequency settings lets you override the BSEL into the MCH to force it to use a different ratio. It also sets up other internal things which can have significant effects on stability. It's best to select a Reference Frequency closest to the actual FSB frequency you will be running. So if your running at 400MHz Host Clock setting, I'd recommend selecting 400 for the Reference Frequency.

DDR Frequency (or is it called Memory Frequency) is the other part of the equation that makes the actual ratio clock ratio. GTJ has a nifty spread sheet that does the memory speed calculations. But if you select BSEL=400 and DDR=1600 it will run the memory at the host clock speed. If the host clock is 333, final memory speed will be 1333. If this works, then you can just start increasing the host clock again until you find where it's no longer stable.

If it doesn't run at Host Clock = 333, BSEL=400, DDR=1600 then you have some choices. You can try increasing the timings (bigger numbers) this will give a little lower performance but can increase stability. Or you can try setting DDR=1333. So at Host Clock = 333, BSEL=400, DDR=1333, the actual memory frequency will be less than 1333 (I don't know off hand what it will be). Now try booting with this setting, if it works, then start raising the Host Clock again until you find the point it's no longer stable.

Once you find the stability point you can again try raising the voltage to go faster. You could try increasing the timings to go faster, but often that results in lower overall performance. Setting the timings is really a lot of trial and error. I don't know a good method to step through them, other than just playing around with them. Maybe someone else does other than just playing

The first timing CAS Latency or perhaps its called tCL, I don't remember exactly, but it has a big effect on performance. A lot of other DDR timings get automatically configured are based off the CAS latency so it effects a lot of things.

Command Rate also has a big affect on performance. When set to Auto it will run 1T with 1 stick per channel and 2T with 2 sticks per channel. 1T is better performance, but it could be less stable.

Once you have settled on what seems to be the maximum memory speed, then you can adjust your CPU multiplier back up to try to get as close to the maximum CPU speed you found earlier.

Getting the best possible memory performance setting is tricky, it could be a trade off between Frequency, timings, and command rate. Everest by Lavalys is a good way to check DDR performance. Though even when measuring performance you can trade off between bandwidth and latency.

If you can raise the host clock more with our having to increase the voltage then I'd go for it. Do you have a fan on the MCH, or water cooling for the MCH? What kind of CPU heatsink are you using? Is it a horizontal radial style that blows air in all directions so it's also blowing on the MCH heatsink?

[RRGHOST2006]

I think you mentioned there was a Profile 1 listed for your memory that ran at 1333. I'd start by selecting that, then selecting manual so your starting out with the profile settings.

WHAT EXACTLY DO YOU WANT ME TO DO HERE???

SORRY I DONT UNDERSTAND WHAT YOU MEAN
SELECT THE PROFILE 1 AND USE THOSE SETTINGS WITH MANUAL OR
USE PROFILE 1

well anubi im using a northbridge small i believe 20mm cooler
that hooks into the small black clip that came with the mobo
im using the CNPS9700 LED zalman CPU COOLER
ARTIC SILVER 5.1 PASTE
AND A http://www.newegg.com/Product/ShowIm...e+Panel+Window
Tagan Aplus CS-EL Diablo Black 0.8mm SECC ATX Full Tower Computer Case - Retail

Extreme sports athletes have nothing on the Tagan’s CS-EL Diablo case when it comes to big air. The bigger the fan the more air it moves at a given speed. The slower a fan spins the quieter it is. When you put those facts together it leads you to one conclusion—big fans are better for keeping your computer cool. Tagan took this to heart and put a 250mm fan in the front of the case and a 360mm fan in the side panel. If you really think you need more air movement you can put a 120mm fan on the back panel.

THIS CASE IS AMAZING
IT BLOWS AIR LIKE NO OTHER I DID A LOT OF RESEARCH TO FIND THIS
AND ITS HUGE!!!!!!!

Hey Where Is The Mch You Are Referring To On The Motherboard

what Exactly Do You Want Me To Do Here???

Sorry I Dont Understand What You Mean
Select The Profile 1 And Use Those Settings With Manual Or
Use Profile 1

Never Mind Man I Got You I Dident Know I Could Do That

Thanks Bro

Well As 333 Fsb And Using Profile 1 then selecting manual
With Reference Frequency At 333

Result = Fail

Wont Post

im going to bed now have to be at work in 5 hours
ill do more testing tomorrow thanks for all your help
everyone who has helped me

see you tomorrow
