E8500 E0

Jedifragger, if I was to buy a 'few' of these to raise chance of getting a E0, can I return the rest (unopened ovbiously) under DSA ? i.e can you return part of an order under DSA?

I no longer work at OcUK so cannot say, but they're not being sold as e0 steppings so I would say 'officially' no

Well i wouldnt have to give the reason to return them under DSA other than they were unwanted. Its just whether you can return part of an order.


Ive sent a web note to find out fro sure.
 
Right I finaly got my new rig built.

Currently running 4.0GHZ 500x8 at 54c under full load on occt @ V core of 1.3

The bios on these P5Q's has a lot!! of settings... so far only changed the FSB/multi and vcore... no idea what else to set to what! I can see some fun coming up...

This might help. it's a BIOS explanation for P5Q Pro but many of the same options are available on the E, Deluxe, etc.


P5Q Pro BIOS explanation.

Some of the options in this guide may differ slightly depending on the CPU you are using and BIOS revision. This guide is based on the 1004 beta BIOS for the P5Q Pro and covers the "Ai Tweaker" section of the BIOS.

Ai Overclock Tuner - Options are Auto or Manual. Set to Manual to start Overclocking.

CPU Ratio - Specifies the minimum and maximum CPU multiplier available to your CPU. Adjusting this value changes your CPU clockspeed accordingly.

FSB Frequency - The default value of this will vary, depending on your CPU. Can be raised in 1MHz increments or a value can be keyed in directly.

PCI-E Frequency - This specifies the Peripheral Component Interconnect - Express frequency, default is 100MHz, maximum is 180MHz and can be raised in 1MHz increments.

FSB Strap to North Bridge - Specifies the NB strap to be used. Default value will vary between 200-400MHz. Changing this value also changes the dividers available for memory.

DRAM Frequency - Specifies the operating frequency of your memory. Default value will vary, depending on your memory and CPU. Frequency will vary accordingly based on FSB and NB strap.

DRAM Timing Control - Allows you to manually specify timings for your memory. Setting these values too loose or too tight can cause your system to not POST, thus requiring a CMOS reset.

DRAM Static Read Control - Disabling this will, in most cases, enhance DRAM overclocking. Best set to Disabled.

DRAM Read Training - Enables/disables memory data optimisations. Disabling this might help increase memory OCs.

MEM. OC Charger - This is some kind of Asus thing I believe which they claim can help boost memory performance. Options are Auto, Enabled or Disabled. Probably best left Enabled. Pick your poison for yourself based on your experiences with it enabled and disabled.

Ai Clock Twister - Specifies the DRAM data driving strength. Setting this to moderate is a good starting point. If your having memory related problems, increasing/decreasing this value might help, or indeed solve your problem completely.

Ai Transaction Booster - Another Asus feature. Setting this to Manual brings up the following sub-options for manual system performance configuration.

Common Performance Level - Options are 1-31. The higher the value the better compatibility with your RAM. Setting a lower level will enhance memory performance.

Pull-in of Chan A/B - The number of these options that appear depend on DRAM frequency and NB strap. Enabling these supposedly "Enhances" DRAM on channels A and B. Beyond that I'm unsure as to what exactly these options are supposed to specifically do.

CPU Voltage - Min-Max values are 0.85000v to 2.1000v respectively in increments of 0.00625v. You can key in a value within this voltage range instead of having to hold "+" down until the desired voltage comes up.

CPU PLL Voltage - Values range from 1.5v to 2.78v in 0.02v increments. In a nutshell, before anyone asks, a CPU PLL is a low voltage differential signal. Raising this may help stabilise high FSB's on the CPU.

FSB Termination Voltage - Values are 1.2v to 1.9v in 0.02v increments. Essentially, FSB Termination sets the final line resistance in traces. Without this option there would be a lot of "noise" going on. Increasing FSB termination can reduce this noise, better calibrating things within the traces when overclocking. This is a largely hit and miss approach as there's no way of knowing the specification for the circuit, so, funnily enough, the answer to if you should use this or not is "play around and use whatever works best."

DRAM Voltage - Options are 1.8v to 3.08v. Unless you happen to live in a sub-zero freezer, setting voltages above 2.2v with passive cooling isn't a good idea, and going above 2.4v isn't such a smart move with a fan blowing over your memory, either. Default is 1.8v, like most other DDR2 boards.

NB Voltage - Options are 1.1v to 2.26v in 0.02v increments. No more than 1.4v should be required for FSB's in the range of 425 - 500MHz.

SB Voltage - Options are 1.1v to 1.4v in 0.02v increments.

PCI-E/SATA Voltage - Options are 1.5v to 1.8v. There's no reason to raise this value above default other than if your trying to overclock the PCI-E bus.

Load-Line Calibration - Best set to Enabled, this option directly helps improve Vdroop.

CPU/PCI-E Spread Spectrum - Both options are best left Disabled. Setting them to enabled does nothing but help control EMI (Electro Magnetic Interference).

CPU/NB Clock Skew - A method for generating clock signals, its an effortless way to try and gain more stability without the need to adjust the signal integrity of individual hardware components.

CPU Margin Enhancement - Present as of the 1004 beta BIOS. This option may allow for higher FSB frequencies when set to "Compatibility" on certain CPUs.

Ok well here are a couple of pics of my current O/C attempts.

What do you think?
 
Coincidentally, I've just completed my first run at 4Ghz:



I've taken it to 4.2Ghz, but it craps out in Orthos pretty quickly. Early days yet, but I'm suffering the same low FSB problems that I had with my E2160, can't get it to post past 460.

Also, as expected, temps are at tad high: I set vcore at 1.3v, and it idles at 43/44, which is really where I like to be for day to day use, so not sure how much further I can go. Looking for a stable 4.2

Any suggestions welcome, especially if you know the board.
