P4 3.0C

[rhawk79]

I was wondering if someone could offer a little advice. I the ASUS P4P800 Deluxe with 2 sticks of 256 XMS PC3500 and a P4 3.0. I'm new to overclocking but here is my configuration:

P4 3.0 @ 3.5 (fsb = 230)...Stock cooling
Memory Timings: 2-3-3-7
fsb/memory ratio: 5/4
Case: coolermaster atc-201 aluminum - 4 fans @ 1900RPM
Power supply: 400W PSU I'm reusing from a SuperMicro server case
All voltages set to auto
Turbo mode, Memory Acceleration: Enabled

Normal system/cpu temps: 32-36C
After playing a game: 40-42C

My system is stable at 3.5 but Warcraft 3 will crash at 3.6 or 3.7. However temperatures are ok even when running that high. Any idea on what I can do to make it stable at higher speeds? I was considering getting an Antec True430 PSU, will this help? Faster fans maybe (although I'm not willing to make my system louder)...Will the Antec PSU allow me to reach these speeds without raising voltages?

Thanks!!

prolly not a PSU issue. upping the vcore my help

Also upping the memory voltage. Also may want to look at using the 5:4 divider to see if that helps increase the FSB.

You shouldn't run PAT at a 4:5. Turn your performance mode from Turbo to standard, you'll see a boost in memory performance. My understanding is that, short of significant cooling, you're not going to get any of the Northwood chips to o/c beyond 3.6. 0.19-micron architectural limitation?Which is why my 2.4C > your 3.0C. Wanna trade? LOL (j/k, unless you really do then we'll talk )

all of the online benchmarks have shown 10-15% improvement with PAT enabled. why would i want to disable it?

Its a trade-off.

Either you stick with your OC, and keep PAT on.

Or, you disable PAT, and see if you can OC farther.

If you can OC farther without PAT to the point that your new OC is better then when you had PAT on, you keep it.

OCing, especially with all the bells and whistles of P4s (ratios, PAT, MAM, Performance mode, yadda yadda whatever the mobo companies wanna call it) makes it all a matter of experimentaion. And no, not that kind of experimenting

I don't think PAT works unless you run at 1:1 anyways. No need to enable it.
Have you tried to see how fast your memory will run? You might be able to
run 1:1. Then you will be able to get the advantage of PAT.

i can run 1:1 with the memory running at 400 but then I can only get the fsb up to 210.

My benchmarks have shown that 5:4 with a higher fsb but slower memory is faster.

Hmm, but now that I think of it, I'm going to try less agressive timings and see if that will allow me to go past 210 with 1:1

 

[rhawk79]

double post whoops

 

[rhawk79]

well i wasn't able to take the fsb any further than 233. even after lowering the memory timings 240 still wasn't stable. also, even with lower timings i could not go higher than 210 with a 1:1 ratio. corsair will be releasing pc3500LL soon, at lower latencies, and I'll sell and switch to that, so maybe I'll be able to go higher at 1:1 with those modules.

But I will say this, since I'm staying at 230 I decided to lower the memory timings as low as possible. Went from 2-3-3-7 to 2-2-2-5 and man when I booted up the system was as SNAPPY as it's EVER been!!!!

hmmm PC3500 should run at about 219MHz FSB if you do the math. You should be able to hit
that with relaxed timings running 1:1. Right? What are your bios settings when you are only
hitting 210 1:1?
