Your RAM combination may be your issue.

IMHO, I only OC (what little I do) on systems with fully matching RAM. Esp when they have different performance metrics like yours.

Try pulling out the 1GB and see if you do OK on just the 2x 512 (or the other way around - pull out the 512s.)

Agreed on the RAM

Personally, I would pull the 512 sticks, and add another 1GB stick (maybe even play it save and buy a 2GB set). That way you run Dual Channel with 2GB. Right now, you'll be running Single Channel.

You can run dual channel with 1 X 1GB and 2 X 512MB sticks. Dimm 1 and 3 take the 512's and dimm 4 takes the 1GB which will yield dual channel. For informative purposes, if you have 2 sticks that are SPD identical and 1 stick that is SPD identical to the 2 sticks and is the same capacity of the 2 sticks then you can run dual channel mode. Thus 2 X 256 in Dimm 1 & 3 and 1 X 512 in Dimm 4 will allow for dual channel mode.

You might find that you must run a 2T command rate though and 2 X 1GB would give you 1T.

For the A8N32-SLi

HTT and LDT

In the A8N32 there are 2 hypertransports on which to focus. The main conventional HTT is calculated with the HT X K8>NB multiplier X2. The default is HT=200 and K8>NB=5X = 1000. The second one is SB>NB Frequency (you get at this one by turning "auto" off in the SB>NB Overclock item in the Jumperfree page) X SB>NB Multiplier X2 = 1000.

When overclocking by increasing the HT the multiplier should be lowered to maintain the HTT at, or below, 1000 (X2). So for HTs in the range of 201-250 the multiplier should be set to 4X and for 251-333, at 3X.

This applies to the normal HTT. When it comes to the secondary SB>NB HTT it is less stipulated. Some claim that it is best left at 200 X5 and some others believe it should match whatever the primary is set to: i.e. match the SB>NB frequency to the FSB and keep the multipliers the same. Try either way though I find the the secondary way is the most appreciable.

The "Linkwidth" setting for K8>NB and SB>NB are left at 16X.


Memory timings

The Memory Clock Frequency is derived by the FSB and Memory divider/multiplier settings. A bit of an issue is that the memory divider is expressed as frequencies and not divisors.

ie: If the FSB is set at 250 and the memory divider is set at the default 200 then the resulting frequency is 250. This is because the "200" really means 250 X 200/200 or 1:1. A setting of 166 there with the same 250 FSB would give you 250 X 166/200 or 207.5. Now the BIOS boot screen will report it at 166 but any utility (like CPUZ, CBID, etc. will report the correct frequency.)

One thing worth noting is that this MB also provides memory multipliers above 200. If you're overclocking the FSB, you might as well just forget about them. They would be of use only if you want to keep the FSB at 200 but want to run the memory faster than the FSB. Now this can be done with the right, premium (DDR450, DDR500, etc.) memory modules but the FSB on this MB can easily do anything this memory can do so I question, "Why Would You?"


Additionally

The Peg Link

This is the ASUS BIOS utility for overclocking the video card by up to approximately 12%.

The Auto Overclocking Options

Don't use this

The "Cool & Quiet"


This is the setting that will allow you to govern your system. You can think of this as the "Underclocking" setting.

You got a good setup josh, you should be able to get some extra speed out of that CPU. Once you get the RAM issue resolved, let us know.
