ASUS P5N-E SLI 650i Thread

I love the profiles.
I save each OC on profile 2, then every time I get a stable one I save it to profile 1.

But I do know that there is a way to overclock JUST your CPU and not your ram....which is what I want to do since I have DDR2800mhz ram.

As far as that goes, to keep stable you should generally run a 1:1 divider.
So if your FSB is 200, your RAM should be @ 200 (BIOS will read 800 for FSB and 400 for RAM, your RAM will be 1/2 underclocked.)

Digikid, I don't know much about the E4300. What is the stock FSB, and is your multi locked or unlocked?

Your maximum OC to keep your RAM at it's fastest rated speed, at a 1:1 divider, without OCing your RAM, your FSB will be at 400. At that speed with the 9x multi, you will reach 3.6Ghz. (400FSB times 9 = 3600Mhz) And your RAM will be running @ 400Mhz as well (there's your 1:1 divider, 400:400, your bios will read FSB 1600 and your RAM will read 800, your max non-overclocked RAM speed)

To attain higher than 3.6Ghz (if your chip is not already too hot) You will either need a different multi, if it is unlocked, or overclock your RAM (which most people end up doing!) Your RAM is basically the same as mine.
In fact, I can't believe how many people have the OCZ Gold/Plat. DDR2-800 chips! So many. I suggest you get the 4xxx series BIOS so you can OC your RAM properly.

DDR2800mhz ram.

Sorry, meant to touch base on this.
It is not 800Mhz, CPUZ will show you 400Mhz for the RAM when it is at it's max stock speed, DDR2-800. DDR is dual data rate, so when you set it to 800 in the bios remember it is doubled already, meaning it is actually at 400Mhz times two.

Intel chips are quad pumped, so a stock FSB on my chip is 800, which has been quad pumped from the 200FSB really.

Okay, for my OC here's what I changed in the bios settings. Nothing else was touched. I'm using the latest update.

ADVANCED menu

Chipset
-Spread Spectrum Control
-CPU Spectrum: disabled
-PCIE Spectrum: disabled

JumperFree Configuration
-AI Tuning: Manual
-Voltage Control
-Vcore: 1.56250v
-Memory: 1.920v
FSB + Memory Configuration
-FSB Memory Clock Mode: unlinked
-FSB (QDR) MHz: 1400

That's pretty much all I changed on my computer. As with anything, your mileage may vary.

I think I understand.

So all I have to do is put the muilti ( unlocked 9 ) to 9 and thats it? Nothing else?

You need to change the FSB also. It was confusing to me at first.
The multiplier should already be set to 9 in the bios.

I changed the FSB to 1400. The processor whatever is quad pumped. So 1400/4 is 350. Since the multiplier is 9, 9x350= 3150. That's the MHz and that's what my computer is on.

Since you are shooting for 3500 MHz, you'll need to change your FSB to at least 1560. 1560/4 = 390, 9x390 = 3510 MHz.

It's not going to work that easy. You'll have to adjust the Vcore and quite possibly the memory voltage and maybe making memory timing adjustments (I left that on Auto).

I am confused. LOL!!!

LOL Welcome to my world. I had to figure stuff out. When you get to the bios screen go the Advanced tab on top. When you select that you should see some items. Select JumperFree Configuration. You should see more options. Change AI Tuning to manual and it should unlock the rest.
You should see Voltage Control and FSB+Memory Config. Each one has it's own adjustments.
I started first by changing the FSB (QDR) MHz. That's where you need to input 1560. More than likely it won't boot up. You'll now have to tweak your settings. That's the fun part. Lots and lots of resets. My earlier post showed what I changed before making all these adjustments.

Can you do me a HUGE favor? The BIOS chip on this board....is it in a Socket or is it onboard....I think that i may go the safe route and get a Bios Saviour for it. LOL.

What are your ram timings at right now? Since my ram is slightly more powerful than yours will I need to adjust that any?

I have the slightest idea about the bios chip.

I left my timing on Auto since I still don't know how to mess with it. Loose settings, tighter settings..
From CPU-Z it's showing 5-5-5-31 2T. Whatever the hell that means.

Anyone running SpeedFan with your board? I'm trying to figure out what temp reading is what..

Temp1 = CPU
Temp2 = MB
Temp3 = Northbridge ??? <--unsure
HD0 = hard drive

Am I correct?
