can't get fsb to 250 with a new 2.6c and PC4000

[marthastewart7]

so i can't seem to get fsb above 233 with my new 2.6c, OCZ PC4000 and ASUS P4C800-E Deluxe. here's the scenario:

(without agressive timings) i've elevated the voltage for both the ram and the cpu, but no matter what i do when i bring the FSB above 233 either it won't boot or i get errors in memtest.

i've burned the system in at 233 without problems... but the whole reason i got the PC4000 ram was to run a 1ghz front side bus.

anyone have something for me to try? -s

You might have gotten one of those unlucky cpus. 🙁
What are your settings for voltages and ram settings.. maybe people can help then.

p4 2.8 533fsb
intel mobo
1gb rdram pc 800
radeon9800 pro
120gb seagate s-ata

Download the latest version of Motherboard Monitor 5. You can find it by putting MBM5 in your search engine. Under the main menu set it to record a log to text (I put the text file on my desktop), taken at 5 second intervals (for better accuracy of the log), with a high number of recordings (I set mine to 60 so I'd get 5 minutes of log).

Now start the program. When your system crashes, restart the computer and look at the log file. Get back to us with your highest and lowest voltage levels for vCore, 3.3v line, 5v line, and 12v line.

Oh, and I recommend you set yout CPU vCore to 1.70v and your vDIMM to 2.75v as a baseline for attempting the "1GHz bus" overclock.

From my previous post, also give us your highest and lowest CPU and chipset temps.

Is he using 5:4 or 1:1?

 

[Crashman]

I'm assuming he's using 1:1 since he has PC4000 memory. That RAM should handle up to 2.85v for extended use.

got a reply back from an OCZ tech with some configuration tips. since the OCZ PC4000 ram is supposed to run at least 250 fsb... if i can't get it up there they'll replace it or something. hopefully it isn't the cpu (though that's still under 15 day warranty) btw here's what he sent:

Could you try the following settings and see if they work for you? If not, please try one module at a time and find out if one module is causing problem. Please update us as soon as you are done with your testing.

AI Settings: Manual
CPU External Frequency: 250
DRAM frequency: DDR400 (1:1 ratio to set actual memory frequency to
DDR500 based on CPU frequency)
AGP/PCI frequency: 66/33
CPU VCore voltage: 1.675
DDR reference Voltage: 2.75
Performance Mode: Auto

Configure DRAM timing by SPD: disable
CAS latency: 3
DRAM RAS precharge: 4
DRAM RAS# to CAS# delay: 4
DRAM precharge delay: 8
DRAM burst length: 8

took the cpu/mb/ram to a friends house who has his p4 2.4c clocked up to 3.2ghz. swapped the ram around and had no problems running a high voltage and overclock. swapped the cpus and *poof* couldn't go above 3.06ghz again. so it's unfortunately obvious now that i got a bad luck cpu that doesn't want to oc. damn. maybe i can ebay it, lose $20, and try again. oh well. anyone wanna trade? 😛
