P4T-E w/ 1.6a at 2.24 GHZ (jumper settings)

[lataf2]

Had some problems with this.. The jumper settings are not documented for the asus P4T-E motherboard above 133mhz. Here is what I used:

140mhz (6/7/8/9/10) off/on/off/on/off
136mhz (6/7/8/9/10) off/off/on/on/off

System Specs:

Asus P4T-E, malay 1.6a @ 2.24ghz (140fsb), kingston RDRAM PC800 (3x), default voltage, stock intel fan w/ artic silver 3, lian li pc-7 case and cooling.
With MBM: CPU IDLE: 31C MB IDLE: 29C CPU MAX: 40C

Yuck.

You should have bought some Samsung so you could use the standard 4x memory multiplier...At 3X, your RDRAM system performs no better than an overclocked DDR system. Actually, it offers even less performance at 3x...since you are only doing 2.24GHz.

You might want to try the pin trick to increase the voltage to your processor...so you can hit 2.4GHz.

even with 1.65 it crashes at 4x.. that's with 120fsb

also, sis sandra gives the memory a rating of 2867mb/s which is far above the PC2100 2070mb/s

ken,

do you know where the voltage setting is on this mb ? I can't find it in either the old or new docs.

RDRAM is supposed to get like 4gb/sec, not 2.8

The main disadvantage of the P4T-E is that you don't get access to the AGP/2 and PCI/4 dividers through the bios. As a result, you can't hit much more than 4x133=533FSB through the bios. By using the mainboard DIP switches, with the reference information from the P4T (not P4T-E) manual, you can easily do up to 4x150=600FSB. Unfortunately, when using the mainboard DIP switches on the P4T-E, you lose access to the voltage options. And thus the only way to change voltage on the P4T-E, as necessary to overclock, is to perform a mainboard modification, or use the PIN TRICK (as discussed in other threads).

The Abit TH7-II is much easier to use, as far as overclocking, because both the voltage options and an option to lock AGP and PCI within spec are available with the latest bios.

The DDR boards do as high as 2900-3100mb/s when overclocked. With RDRAM at 533MHz, you do 3300-3500mbps in Sanda. With further overclocking of RDRAM to near PC1200 speeds (as people have hit on the P4T-E, and on modified TH7-II boards), you can do close to 4000mbps in Sandra.

I can't find the thread which talk about the "pin trick". Can someone please post a direct URL or the title of such an article ?

thanks!
