AndyC, or whoever else has run Ep-8kta3 @ 166mhz fsb

[JML]

I've never run it that high before, and any I would appreciate some experiences from those who have already done this.

BTW- This is my setup - Ep-8kta3 (of course); Tbird 700mhz; 50x CD-ROM; Western Digital 20.5GB HDD; Geforce2mx; Netgear NIC; Aureal Vortex2; Generic 300w PSU

Get yourself some real deal memory first that is gonna cut it. Make sure you ain't got no dodgy old 4.3Gb Seagate drives that are gonna pop or AMR modems or you rely on the AC'97 codec.

Remove the Northbridge cooler, apply thermal grease (Dow Corning 340 or AS2), replace with a lapped Blorb or equivalent. This Northbridge is gonna get hot !!

Set your voltages as follows as a rough guide when using an AGP 4x card :-

[order=1]
[#]I/O = 3.65v
[#]AGP = 1.85v
[#]CPU = 1.85v (or greater if you can by a modification)
[/order]

Those are the settings I used to acheive the 166Mhz on that board

I have Micron pc133 256mb RAM. Would it help if I had a newer Bios? I was going to update mine but I don't know what one I have! On the Epox site it appears they go by date, but I don't know where to find the date of mine. Also, what will the AGP and PCI slots be running at @ 166 FSB?

Thanks for your help so far Andy =D, I appreciate it.

BTW- my cpu vcore goes higher than that and I've done no mods to it, I'm guessing my bios isn't too old

 

[wild_andy_c]

Flash to the latest BIOS regardless.

You are getting perhaps 1.92v or something I would imagine, that is normal from trying to obtain 1.85v on a lot of boards - it helps systems run more stably at default voltages.

When you go that high how low do you have to set your memory timings? Do the systems benchmark faster with cas 3 at higher FSB or with cas 2 and a lower FSB?

This multiplier for a 133mhz FSB is 1/4, so that your stock system clock would be 33mhz. At 166mhz it would be 41.5mhz because you go 166 * 1/4 = 41.5. With the 8k7a, like they were talking about on the main page today, you can change the PCI clock multiplier to 1/5, allowing you to put your FSB to 165-200mhz without going way out of spec.

Hey wild_andy_c are you saying the Ep-8kta3 bios allows for overclocking past 166 fsb? How did you ste your divisor to 1/5. I am hoping Asus sees the light and allows for at least a 200 fsb in future bioses.

 

[Morphoius]

There was a bios update that allows for overclocking past a FSB of 166 mhz. i think that the 1/5 pci thing is in that bios as well.

This is for the 8k7a not the 8kta3
