PDP Systems Patriot XBLK PC3200 Database

Recommended Posts

Hi I would like to collect some overclocking information for PDP Systems Patriot XBLK PC3200. This may be helpful information for people start to tweak their PDP. Please post your informations here:-

 

Speed, Size, Timings Memory Voltage, Prime95 stress (hours), CPU Core + Weeks.

 

Here is mine:-

 

280MHz, 2x512MB, 1:1-e-2.5-4-9-4-13-17-2-2-2-2-4-3120-5-interleave-i-0-Level7-Level4-7ns-5ns-256-e-16x-7x-d, 2.9v, 12 hours, Winchester 3000+ 0508

240Mhz, 2x512Mb, 2.5-3-3-6, 1:1, 2.8V, Winchester 3200+, DRAM Drive strength 8, interleave enabled.

 

I'm not too sure if it was the major cause, but initially with interleave disabled, it would run fine untill i benched with Sandra for a second time - BSOD. is there any performance hit with interleave enabled/disabled? Also where is the option to tweak the command rate? Must have eluded my eyes, thx

512x2 @ 290MHz | 2.7V

2.5-4-3-6 1T, 1:1

AMD64 3000+ Winnie [CBBHD 0449 MPM]

Interleave Enabled

 

One thing that I've noticed is that these chips don't like high voltages. I get less stable when I go up to 2.83-2.9V. I was running 280x9 at only 2.6V with 2.5-4-3-6 1T timings, 1:1.... So I don't know if that's the same thing you guys experienced, but you may want to give it a shot.

i've jus ran Sandra mem bench and a round of 3DMark05 with no BSOD. i'v cut down to 7 for dram drive strebgth and timings are 2.5-4-3-6-7,1:1,2.8V interleave enabled.

when i use 2.5-3-3-6 it will crash. btw chennhui are u on stock cooler ? i dun want to be pushing too hard on stock but its an addiction thats hard to put don :rolleyes:

Thats how mine behaves too. I can hit 300 FSB @ 2.5-4-3-10 using 2.6v but if I use more voltage I get errors.

RiZZo, yes it is on stock heatsink. In additional to that, I also attached high flow fans on top of the mosfet blowing downward, so as the CPU, RAM, mosfet and NB will benefit from fresh air intake. CPU temperature when priming is Max 55c, occasionally, dropping to 40c. Room temperature 30c. Make sure you monitor your CPU temperature using ITE and make it alert you by sound when ever CPU temperature is too high...

 

You knew the discussion of tRAS right? OS corruption can be easily reinstalled, but data corruption is a disaster. Try tRAS of 9, tRC = 12, if you believe in those discusion. :)

ok i've lowered my timings down and managed to hit 280x9 :nod: BUT i have yet to get at prime stable as my last mem timings were 2.5-3-3-9-12, 2.8v. left prime on but when i came home my rig had rebooted itself lol.

 

will try 2.5-4-4 and see how it goes. thx for all the help mein bruthas
