need help in oc the cpu

[elemental_pk]

(sorry about the english)
Hi
I wanna oc'ing my cpu and i need a help in set the bios options.
q6600 G0 + tuniq tower
P35 DS3L
2GB 800MHZ 4-4-4-12 (CORSAIR)

1. What is the System Memory Multiplier and to how much i need to set this ?
2. Where in my bios i set the memory ratio (the 1:1, 2:3...) ?
3. Where is the part of the memory timing ?
4. What i need to set in the all voltage ? in the CPU Voltage control set the preliminary voltage ? I not understand the +0.2, where it needed - in need to set this to 0.2, 0.4, 0.6 or do plus 0.2 to the existent voltage ?

I hope you understand me...

It's Gigabyte mobo, right ?

Go to MIT by pressing ctrl+F1 in BIOS.

come on!you still dont recognise that model number?of course its a Gigabyte board!

press CTRL+F1 before you go into M.I.T.not after.and you will see the memory timing menu.

leave system multiplier on stock and select 1:1 for FSB:memory.

how high you want to overclock.that will help me give you some estimate setting.list you VID as well by using Coretemp.

im abit frustrated by my E2160+650i thats why i type in such way.slicesoul odnt be offended!

but its true though!hehe

i didnt have the 1:1 option... i think that the "system memory multiplier" is instead this - 2.00, 2.50, and some like this.
about the "how high you want to overclock" - highest than i can.
what its a VID ?

1:1 is equivalent to system memory multiplier of 2. Gigabyte motherboards like to do this I suppose. You can either do the math seriously, or just play around with the settings a bit.

VID is voltage identification. Pretty much it's what your cpu's voltage is identified with.

 

[iluvgillgill]

VID you can look at it as the stated default votlage for specific CPU.its different for every CPU even if they are the same model.

[elemental_pk]

my vid its 1.325v

My mistake.

 

[Lupiron]

EleMental! ::chuckles.:: Hopefully your VID isnt 1.3250! Thats the worse possible one! Anyways, do me a favor and DL then run core temp, the newest one should work! When you see your VID with this program, run any powerful program, and make sure the VID doesnt change at all.

You may wanna turn off speed step as well.

If your VID changes! Yippie! If it stays at 1.3250, well... thats the worse VID, but you can still reach 3.6!

Dude my english not soo good soo pless talk clearly and not in slang.
I not understand - 1.325 it is my VID or it is not ?
what is the good thing and what is the bad - if the VID chagned or if its not changed ?
Is it another way to check my VID ?
Is it the VID is not the same for all the Q6600 processors ?
Give me pless a link to the newest core temt, cuz i dont know what is the version of the new one !!!

Apparently, VID for every cpu is likely to be different. Download Coretemp and check.

According to Lupi's research, the lower the VID, the better the overclock, so it's best if you have a low VID Q6600.

 

[elemental_pk]

The CoreTemp is suck...
I check in CPU-Z and there in the core temp written 1.136v and its move up to 1.168.
When i run a prime95 test its go up to 1.264 at max'...
Soo.. its is good ? i think its is good...
What i need to do now ? i think i need the MEMORY voltage too.. how i check ?
aaaa... thx to all for the help

 

[Lupiron]

Uhhh... You HAVE to use core temp to list the processors VID. CPUz will change, just like you saw!

Prime 95 jumps it up to 1.264, hmm? ::Sniffsniff.:: I smell a 1.3000 or higher! Waaahhhh! Dont tell me, you bought a retail box recently to get it?

You may wanna disable speed step in the bios or you will get random readings like that, hehe! It sets the multiplier down to x 6, which makes it look like its runnin' on less power.

BTW, Core Temp, CPUz and HWMonitor are the three you wanna watch, as well as the windows performance monitor. Those three programs and WPM tell you just about everything you need to know!!

--Lupi!

 

[elemental_pk]

🙁 didnt understand, my situation is good or not - to how much i can go with the oc ?
soo.... what we do now ?
to how much set the cpu voltage - to the lowest: 1.136 or to highest: 1.264 when its on X9 ?
and to how much set the ddr2 overvoltage ?

 

[Lupiron]

Wait.. it doesnt work like that! The BIOS VCore will change when ya hit windows, and then that will change when the processor is under use, and requiring some serious power.

Here is how VCore works. You set a Bios Value! Say, 1.000
When you set that in the bios, Vdrop will apply, to protect the processor for over voltage swings, it lowers the VCore from 1.000 to, say... 0.9750

So you have a VDrop of .0250

Then in windows its gonna idle around that voltage. But when you put strain on the processor and make it have to work, it'll lower even more. Different parts, boards and such will effect the values.

So it goes from around 0.9750 to .93500 when under full load. Again, each mother boards VDroop and drop can be different!

If that chips speed is high, and it's required voltage is low, Boom! BSOD or other error. Thats because the voltage level tells the processor what to spit out. A 1 or a 0.

If the VCore is just the smallest amount to low for a given speed, it may spit out the wrong value, and as we all know, a single computational error could corrupt the whole amount of data! Be it a program running that bombs out, or just trashes a system file...

Sure, it'd prolly have to be running at a high speed due to other activities before that would occur. You can run a chip at a higher speed all day long, and not get any errors, but prime is a different story!

So First you need to look at what you set your Bios VCore too. Then go into windows, then use CPUz to see what the idle value is in windows, so you know your VDrop. Then run primes small ffts on all cores for 1 min, and see what it is at then.

After you get used to what it does, you can now target a given LOADED VCore voltage.

The higher the VDroop, the worse off yer board is for over clocking!

Why? Because that poor chip will idle higher than it needs for most of the time!!! And you'll never get the power out of your chip that Primes small ffts does. Sooo...

I hope that helps!

soo its the vcore + the vdroop to know what the loaded cvore...
soo know in need to chech what my drop, rigth ?
ok i do it but when a set the vcore, do not chage any another voltage ? only the cvore, rigth ?

 

[Lupiron]

Its the Bios VCore. Then VDrop applies, so windows idle voltage is after Vdrop.

Vdroop comes into play when you draw power from your processor.

So its Bios VCore - VDrop, then - VDroop = LOADED VCore.

Thats the critical part.

So if you had zero VDrop and VDroop you'd be in heaven! To bad, huh?

But you use that formula, then after you know what your drop and droop is, you'll be able to estimate what you need loaded, and can go straight to that amount of Bios VCore that lets you get a value loaded.

[elemental_pk]

ok what exactly to do ???
to take the lowest vcore thet i get in cpuz and to insert this in the CPU Voltage ? (take the voltage when the mult is x6 or x9)
after this go into wondows, run cpuz, put prime95 test and lock how much the Vdroop ?
for example: The lowest vcore its 1.1326/1.264 (x6/x9) and let's say the drop is 0.02 - soo what i do now ? go into bios and adding the vdroop (0.02) to the seted Vcore (1.1326) ? soo its 1.1326 + 0.02 = 1.1526 . its that is what i need to do ? rigth ?
soo now its safe to start the OC ?
(before i start i need the ddr2 voltage also, but lest talk about this latter)

Sorry, I have to sleep sometime!

I meant that when you select a VCore setting in the Bios, its not the voltage you will get in windows. The one set in your Bios is the BIOS VCore.

Once you make a selection in the Bios VCore, VDrop will apply. It makes the over all vcore voltage go down a bit.

Lets say you choose 1.1500 in the Bios.

When you do nothing more than boot into windows and look at the actual VCore going to the chip while Idle in windows, you'll see that its lower than what you selected in the Bios.

Thats VDrop. It will go from 1.1500 to 1.1200 or so, for no other reason than you entered windows.

Then that 1.1200 with again go Lower, depending on mother board type. That is called VDroop. When you are in windows and actually run a program that requires alot of processor power, it will again go lower than the 1.1200. And that can range from .02 to .08!

Ideal for overclocking is no VDrop or droop. Because what you set in the Bios is what you'd get.

But since it doesnt work that way, you need to see what your VDroop and drop is.

Next time you are in the Bios, select an even type VCore. Like 1.1250.

Then boot into windows, and look and see what that vcore voltage is. It will be lower than what you selected. Thats VDrop.

Then after noting this field, run prime 95 small ffts on all four cores, let it go for 30 seconds, and look at CPUz voltage for the processor, and take note of that field as well.

Now you can see what your VDrop and VDroop is.

After you learn what your board does, you can easily target a Loaded VCore with no hassle!

Disable speed step! Take the Multiplier Ratio off of auto, then go into CPU options and speed step should be visible. Disable it, and any other spread spectrum stuff you can find!

Speed step is what is stepping that Multi down to x 6, and lowering your CPU speed accordingly.
