Seemingly a good overclocker? so I got one..

Here's the specs:

Antec Three Hundred Case,
OCZ ModXStream PRO 400W Power Supply,
BioStar TP45 HP Motherboard,
Intel Core 2 Duo E7300, 2.66GHz Processor,
Arctic Cooling Freezer 7 PRO,
Corsair TWIN2X2048-6400C4 2GB RAM,
Asus HD4770 Graphics Card - 512MB RAM,
Seagate Barracuda 7200.10 250GB SATA Hard Drive,
LG Super DVD-RW SATA DVD Drive.

Currently stable at 3800MHz (400x9.5) however I really want to get to 4GHz but I don't want to go any higher than 1.3625v VCore.

The question is, have I missed any small detail in the BIOS preventing me to get to this speed? (aside from VCore)

Here's the BIOS:

Code:
Advanced CPU Settings            - [url]http://i28.tinypic.com/2n8rbkw.jpg[/url]
Hardware Health Configuration    - [url]http://i28.tinypic.com/smjn.jpg[/url]

Voltage Configuration            - [url]http://i29.tinypic.com/qpj7yv.jpg[/url]

Here's some overclocked benchmarks:

Any suggestions greatly appreciated! Thanks in advance :-D

I'm far from an expert on these things, but the following is from page 73 of issue 67 ( April 2009 ) of Custom PC magazine.

( They were using an E6750 )

'By increasing the Northbridge to 1.4V, the CPU PLL to 1.6V and the FSB to 1.625V, we could benchmark it stably with an FSB of 530MHz'

Thanks for the information Geoffx, as no doubt you noticed the specs listed above were lifted straight from Custom PC Magazine's CPC Elite 'Budget PC'

Although I checked the processor review I didn't think to check the motherboard review, so I will try these voltage ammendments and let you know how I get on.

Cheers!
 
1.4v vcore should be fine as long as your temps are fine. Take a shot and see if it sticks.
 
Voltages ammended, lets try 400x10 @ 4-4-4-12 - BSOD on boot

hmm, RAM adjusted back to auto timings (5-5-5-15) - BSOD on boot

DRAM Frequency back to Auto - Now not even POSTing

DRAM Frequency back to DDR2-800!

Idea: Maybe they were just testing MAX FSB? Lowest multiplier?

2.66GHz Stock Settings loaded + Voltages ammended + multiplier dropped to x6

FSB up to 530 - Wouldn't POST

FSB Dropped to 400 - Wouldn't POST

Latched DRAM Frequency to DDR2-800 - Booted

NB/SB was only showing 1.09v? - Ammended the voltage from within Windows.

Tried lots of other adjustments, nothing really working.

I need to double check the chipset voltage, Biostars Hardware Monitor is still only reporting 1.09v and currently I'm stress testing the 400x9.5@4-4-4-12 with reduced voltages (temps are 58/59 according to Real Temp)

EDIT: 30 min stress test complete, zero errors. I'll do a proper 8 hour test when I have some spare time.

Here's the final voltages screen..

So just to recap, I'm happy enough with a stable 3.8GHz but would like to get to the magic 4GHz.

What needs changing in the BIOS to achieve this?

As you can see I've tried upping the Northbridge to 1.4v (something which I need to verify as it doesn't seem to be happening) and the CPU PLL to 1.6v and the FSB to 1.625v (both which occured)

Thanks again!

This is what you should change...

Run the gtl's and mch
core1 .63
core2 .63
mch .59

Under clock gen run this
101
200
400
1000

Let me know
 
Thanks for the info Chad11779,

Ammendments made, POSTed at 4GHz, then BSoD loading Windows - I think voltages may need upping again!

Upped the CPU Voltage to +0.1625 (from +0.1500) and the CPU PLL to 1.6v (from 1.5v) and yes it booted into Windows, then BSoD with the usual IRQ_NOT_LESS_THAN_EQUAL error.

So, Voltage would probably sort that out. The only problem is I don't want to run that amount of voltage for a 24/7 machine?

Surely there maybe something I've missed?
 
That bsod is because of your memory. Try running rcomp 4 in your bios. What are your timings?

4-4-4-12, will try RCOMP 4 and update this post with the result, thanks in advance!

Increase the Vcore. That's classic core unstableness.

True, I agree... However the whole point is that I dont want to go over 1.3625v VCore!

Maybe I'm expecting too much?
