Can't overclock my E6400 past 2.52 GHz? D:

[UG0TB4NN3D]

Okay, I'll start with the setup.

 

CPU: E6400 (315*8) Vcore: 1.23 (AiBooster is on auto right now, I change the Vcore to 1.35v when OCing)

Argh...Kinda busy at the moment. Anything else that you need to help me OC, post it and I'll post what it is.

 

 

Thanks in advance.

 

Oh, idle temp is 28C - 30C.

 

A target OC would be around 2.8 GHz.

well first, it would help if you added the specs of your entire system to your sig.

This will help us point out any weak links if they exist

[UG0TB4NN3D]

Alright. Done.

 

Sorry about that. :3

Just wondering, did you disable "Spread Spectrum" in the bios? ( I am assuming your bios has it, if not, ignore me)

Also disable EIST(Enhanced Intel Speedstep Technology), you can always reenable it after you find the clocks you want.

The Nforce4 chipset in not known for its overclockability. YMMV

Another tip: you could try loosening the timings of your ram, or even using another multiplier to underclock it for the sake of a test. This way you only have to worry about one variable to work on. Once the cpu is to your satisfaction, tweak the ram back up. You may also need more vcore to get more out of it.

For 2.8 GHz you need a fsb of 350 for your chip, do you have an aftermarket cooler on it? You will need additional cooling for the cpu if you are going to push more vcore to it. And monitor your temps if you do. I use Coretemp, great program for the C2D.

Well, I'm using the stock cooler, but it's running pretty cool at 2.5 GHz. The highest I've seen it get was like 40c and that's because AiBooster was running it at like 1.45 vcore.

 

Thanks for the advice. I'll try it and post back.

[UG0TB4NN3D]

Well...I got it to 2.56 in BIOS, but I can't find anything other than AI preset things. I can't find out where to change the FSB myself.

[Comp Dude2]

I think the volts might be the problem here, my 4300 runs at 1.325 stock, but then again 1.45 is quite a boost. And that Asus board should definatly have a way of changing the fsb, keep looking

[Tallman]

I found this while searching the web a bit. It was someone elses setup and I took out their actual values as he was running it on phase cooling and you would never be able to use his voltage settings:

 

Advanced menu -> Jumperfree configuration

AI overclocking [manual]

 

CPU core voltage [V] <-voltage of your choice

FSB termination voltage [V] <- may have to increase, try without first

Memory voltage [V] <- check your vendors spec

NB chipset voltage [V] <- usually have to raise this to make memory stabe, but makes more heat.

SB chipset voltage [V] <- modest increase here

CPU lockfree [disabled]

FSB optimize mode [enabled]

Memory optimize mode [enabled]

System clock mode [manual]

fsb [1066 Mhz]

PCIE Frequency [100.00]

Mmory clock [?]

Memory timings [manual]

then set to <-----insert your memory specs below

Cas latency [?]

tRCD [?]

tRP [?]

tRAS [?]

tRC [?]

Address Mode [?]

 

Spread Spectrum:

all values set to [disabled]

 

CPU configuration

 

All values default exept:

CPU Internal Thermal Control [disabled]

Intel Speed Step Technology [disabled]

 

Chipset.

 

All values default exept:

Memory Remap Feature [enabled]

 

Power Menu:

All values default exept:

ACPI 2.0 support [YES]

 

I can only guess that your bios has the same options in it as his board was not the deluxe model. I hope this works for you.

[UG0TB4NN3D]

Thanks, Tallman. I'll go try that and post back what happens.

[UG0TB4NN3D]

Well, I could change all of the other things except for the FSB. I can select it, but when I press enter on it to change it, it does nothing.

 

EDIT:

 

Haha...After a little reading the manual, I found out that the + and - keys on the numpad are used to change the FSB, not the enter key.

 

I've got it at 2.6 GHz, now. Gonna try for 2.8 here in a few minutes.

 

Okay...So...I can't get it past 2.6. Any advice? x-o

 

I tried Vcore @ stock and 1.35v, but that didn't seem to help.

1. What are the rated timings of your ram?

2. What do you have the ram timings set at?

3. Did you up the voltage to the northbranch at all?

4. Did you check the temp of the cpu at idle and full load?

Note: I am going to add a little disclaimer here.

I am not to be held responsible at all for any damage that may occur to your's or anyone else's system be trying these things I am suggesting. Even though I have not had any problem, well, you never know.

 

With that out of the way, I would feel comfortable with vcore set as high as 1.5 for 24 hours a day use, provided the full load temp did not exceed 60 celcius. I feel that you may have to bump your vcore up a bit. BUT, watch those temps You can check for system stability by loading up Coretemp and then run Orthos A good 8 hour fun of Orthos should indicate a fairly stable system.

The rated timings of my RAM are 4-4-4-12. I've got them set at 4-4-4-12 right now. I tried 5-5-5-15, aswell. No, I didn't up the voltage of the northbridge any. And the temp of my processor right now, idle, is 30-34C, Vcore 1.26 @ 2.6 GHz. I haven't checked full load yet, but I'll do that really quick and post back.

 

Core Temp reported full load temps of 59C and PC Probe II reported 49C.
