Ok, I want to overclock my FX57, I have never overclocked an AMD before as I've alway been with Intel until the 57 launched.

I could take my P4 3.2 (Prescott 478) to 4Ghz and have safely oc'ed all my previous machines (intel) safely and I new the in's and out's of my previous mobo's like the back of my hand.

O/cing Intels was easy but there seem to be a bit more to it with AMD, plus my mobo (see sig) has loads of features that probably need adjusting. Once I have my head around everything I know I'll be fine with it

Any members out there with this board care to offer some advice or settings to alter.

Thanks!!
 
Is overclocking that way better than reducing the multiplier and increasing your FSB/HTT?

Or is a case of 6 of 1 and.............

Maybe I'm reading it wrong but I thought doing it the latter way would get more out of the memory (DDR550)?

Anyone

Thanks
 
Thanks for that Dirk, really helpful

Is there a setting in the A8N-SLI Deluxe Bios that I need to lock in order to overclock or it automatic?

There is a setting relating to this (I think it's the one) in the bios that gives me options of - Auto, To CPU and 33.33, it's currently set to auto.

I have tried a couple of the settings you suggested and it falls over when benchmarking.

I remember on my old Abit IC7 Max 3 there was a PCI setting similar to this that I had to lock before I could get anywhere.

All of the current settings in the bios are standard apart from the PCI-e bandwidth which I have increased from 100 to 110Mhz to give my gfx cards a bit more.

At stock under load CPU is low-mid thirties. Cooling is all as sig suggests with 1 Dual Black Ice Radiator and 1 Single Black Ice Radiator, the CPU, Chipset and both GTX's are watercooled. Ram is Corsair Twin X 4400C25 (DDR550) x 2GB

Thanks in advance

Thanks again,

I give it a try tomorrow night when I've got a bit more time.

I put the PCI-E setting back to default until I get the CPU happy and stable at 3Ghz, I'll raise it again and see how it affects things once I've done this.

Excuse my ignorance of not understanding acromnyms but what's the LDT Voltage?

Re setting the multiplier/memory I am right in thinking I was to up to FSB from 200 to 273 but drop the multiplier from 14 to 11 to get 3003?

The next bit confuses me again (sorry - but until I crack this Intel's are easier to clock!!!!) - I set the v Core to 1.55 (or slightly higher maybe as you suggest in your last post) which is easy but the "1:1 divider=273Mhz RAM HT Multi x3" baffles me - is this set as soon as I set 273/11 or is it something else I need to adjust?

Thanks again and thanks for replying!!

Right, I think (or hope) I am getting somewhere at last.

I have my machine running stable with the multiplier set to 15 and the HTT to 201 and the PCI Clock Sync set to 33.33, seems ok at 3.02Ghz. Everything else is unadjusted, left to auto.

I have not yet tried any of the settings that Dirk suggested above yet.

I tried it with the HTT at 205 but it locked up. I shall have a play later on today.

Any other Asus A8N-SLI Deluxe users care to offer some pointers as to any other settings in the bios I need to adjust?

Cheers

Thanks for this Dirk, you've been really helpful.

I'll post my findings when I get chance to have a play.

It's amazing how one Bios varies from another. The Asus seems a bit long winded and complex to me. The IC7 Max3 board was considered the best o/c board you could buy 2 years ago and that was a doddle, the bios was really well laid out and easy to use, the 1:1 ratios were clearly labelled in there as well!
 
I've not really had time unfortunately to fiddle with the bios over the past few days so I'm currently no further forward than the other day.

However, I do have a question -

Is it going to be beneficial for overclocking to change my 4x512 sticks for 2x1gb sticks?

If so, what is currently the cream of the crop ram wise, since I bought mine (see sig) it appears that a couple of other brands have appeared on OCuk (Mushkin and D.Skill) - What are they like?

Thanks
