Hi everyone,
I have a p4 3Gb HT cpu running on asus p4p800 deluxe mobo.In the bios manual settings of the cpu there is a setting called "external frequency. the range of the seting is 0-400 . By default the setting is 200. I raised the setting to 240 and now my cpu runs at 3.6Gb with no problems and is very stable. after booting up and getting on the desktop ,i loaded cpuz and the hyperX ddr-400 2x512 mg ram is only running at 160mhz! not 200 mhz as it should. The default ram timings from this ram is 2-3-2-6 2.6 .I really would like to get the ram to run at 200mhz or near about so i can get the most out of the ram.

Does anyone know what timings i should be running with the cpu set at 3.6Gb.

the cpu specs are:

p4 HT 3.0Gb OC to 3.6Gb
FSB: default 200 OC to 240

Splendid
Unless you've set your memory bus speed manually, perhaps your RAM is just running at a DDR-333 profile from the RAM's SPD? Could you post captures of CPU-Z's memory and SPD tabs?

Thanks mondoman for replying. I have managed to get the speed of the hyperx ram to run at just under the 400mhz that its rated at to run (400mhz).

Its the best i could get out of the ram ,after alot of trial and error with configuations with the cpu. I did get the ram to rum alittle faster past the 400 but it was unstable ,so i stepped the ram back to under the 400 and its stable ,so i guess thats the best settings.

so my final settings and speed for a p4 with dual channel 2x 512 hyperx ram is :

p4 3Gb HT 800 fsb with asus p4p800 deluxe mobo

overclocked to 3.7Gb (stable)

hyperx 2x 512 dual channel running at 193mhz (stable)
