Issues with 250/250 1:1 PC4000 on P4 @3.25

Well I went out on a limb and purchased some Geil PC4000 memory since I read some reviews showing some good memory bandwith boost on P4 Canterwood and Springdale boards. I popped in the board and set the settings of 1:1, 2.5,4,4,7 - 2.8volts at 250fsb. The system runs great but running benchmarks I got marginal increases if not none on some. Why is this? I also get artifacts in Aquamark 3.0 with my memory at 250fsb. Is there some thing wrong? I am really not that impressed with what my results are. Has anyone else experienced bettter than me? I need some insite.

^ Wow, that was informative 😉.

I think the fact that PC4000, etc runs at such sh!tty timings (ie. 2.5,4,4,7 ) is responsible for the mediocre performance. Sure you get a lot of bandwidth at that speed, but in terms of raw performance, in non-bandwidth starved applications, slower memory at lower latency can be equal or better performing (ie PC3200 @ 2-2-3-2).

heh
those timings are evil
geil mem is designed to run on high voltages
I wouldn't be afraid to shoot it up to as high as 3v or more
but you should add extra cooling around your memory (like an 80mm fan pointed at it)

Yah I wish had I had stuck with my PC3200 Corsiar LLC and not read the Anandtech review!!! I got nowhere near the performance they got doing 1:1 with the same memory. I was gettting 380fps in quake3 demo now im down to 320fps. My advice to all that want to do 1:1 with the P4's its not worth it. Stick with the 5/4 with some good Low Latency Memory.


The biggest thing is that I get artifacts in games now with the memory this high. WTF? Terrible. I would send this back and get some Corsair but Im not sure yet.
