P4 1.6A/Ti4400 @ 2128 gets massive 3Dmark2001 Scores

Here's something for anyone pondering making the leap to
PC1066 RDRAM:

My P4 1.6A/Ti4400 @ 2128Mhz @ PC1066 RDRAM has the highest
3Dmark2001 score (11,769) of any P4/Ti4400 up to CPU clock range of 2200Mhz.

Only (5) P4/Ti4400's up to a clock range of 2400 Mhz have
scored higher and only (15) P4/Ti4400's up to a clock range of 2600Mhz have scored higher and most of them were, you guessed it, running the i850 chipset (RDRAM).

Do another search on P4 and Ti4400 and score range to
11,769 and see how the P4 1.6A/Ti4400 @ 2128 @ PC1066 RDRAM outscores page after page P4/Ti4400 DDR machines running @ 2400 and 2500+ Mhz.

Sound to good to be true? Surely I must be running some sort
of handpicked CPU and RDRAM? Wrong. Bought the CPU, MB,
and RDRAM over the counter at the local PC store. I DID make
sure to get the P4T-E with the ICS RDRAM clock chips that
are stable at PC1066.

Other than that, nothing special. I pin tricked the CPU to
1.7 volts and replaced the thermal tape on the stock HSF with some Radio Shack thermal paste.

Raystonn - If you read this, THANKS for the advice over on HardOCP! You are the man. You developed somewhat of a following of RDRAM "converts" over at HardOCP. We want to know where you are posting now!

Sincerely,

WELCOME TO THE FORUMS
Where did you get a hold of PC1066 Rambus? I would love to buy some. Nice score by the way. Here is mine with a 8500 LE 128ddr. http://service.madonion.com/compare?2k1=3282504

PC1066

You may already have PC1066 RDRAM

Alot of the new Samsung 128MB RDRAM 8 device sticks will run at
PC1066 solid. Mine does with no problem at all.

Have you tried running your RDRAM at PC1066?

If you are running a P4 1.8A and ASUS P4T-E I would try this...

Change the jumper on your MB to disable jumperless mode
(BIOS adjustment of FSB)

Set DIP switches as follows:

6 7 8 9 10
ON OFF ON ON OFF

This will give you a 133Mhz CPU bus speed, 33.4 PCI, and 66.8
AGP.

133MHz CPU bus x 18 = 2394 MHz. This may be less than you are running it at now but the PC1066 RDRAM will more than make up for it. Trust me

Set the RDRAM multipler in your BIOS to X4.

This gives Quad pumped FSB (133 x 4) = 532 Mhz FSB.
532 Mhz FSB x 2 (dual channel RDRAM) = 1064 (PC1066 RDRAM)

Here's the catch... When you disable jumperless mode on your
MB you also turn off the ability to adjust your voltage in your
BIOS and you will be stuck the default lowest voltage setting
(1.6v).

1.6v may not be enough to get you stable at 2394 MHz.
You will probably need 1.7v.

Jump two pins on your CPU (pin trick) and you'll be at 1.7v

If you need a link to a site that shows how to jump the pins
let me know. You only get one chance to get that right

Also, if you are running W2K then make sure you install the
i850 drivers that come with your P4T-E. W2K either did not ship with the i850 drivers or they are not right. Unless you install the
i850 drivers with W2K you will get bad performance.

ok, so you DONT have 1066 rambus, you are just running yours at 1066 right?

1066

That is correct. I'm running PC800 RDRAM overclocked to
PC1066.

Mine wont do 1066. Its either the RAM or the frequency chips. I guess I'll buy PC1066 when it comes out and try it.

Hey bignuttz, what cooler are you using on your CPU? and what voltage are you running/do you have it VID pinned?

Update

Well, I figured since I had the high score for a P4/ti4400 @
2200 Mhz with my P4 1.6A @ 2128 MHz, why not move up
to the next weight class.

I went by the local computer store today and picked up a P4 1.8A
and just posted the new top score for a P4/Ti4400 @ 2500 Mhz
with my P4 1.8A running @ 2448 Mhz.

I actually also posted the top score @ 2600 Mhz too, but
there are a few guys just over 2600 Mhz that have me beat,
so I won't brag about that.
