hi folks, excellent forum here, taken agaes to register :wink:
well anyways, although im no noob to computers, have just finished building my second system .. first one was an ancient celery 450 then i got a laptop etc ...
i specifically engaged a tiny bit thought on hardware i was going to use with a view to do some simple overclocking (400mhz or so extra would be fine)
2.8Ghz Intel P4 (northwood/Malay)
Zalman CPNS7000 Cpu Fan
1GB 3200/400 DDR Crucial Ram
ASrock P4VM800 Mobo (BIOS 1.30)
X-Qpack Case 450W
250 Samsung Spinrite HDD
ok, well the problem i have is probably extremely simple, but i figured you guys would give me a straight enough answer!!
this mobo is suposed to be a good overclocking (a bit 'safe') but good, as is my ram and cpu. i can get my pc to run stable on all the defaults .. ie FSB 200 and ram set to 400, however upon fiddling with o/c options i can bump up the FSB to 232 easily (max and stressed temp at 45 deg C) .. unfortunate then i have to lower my ram to 166 :? if i want to bump up any FSB speed i need to lower my ram speed. is this normal, would better o/c ram be pointless? are there any other ways i can keep the ram at 3200/400 and able to bump the FSB up?
I am able to keep max temps under the suggested limit (50 degs C) that the mobo will cut off power. also tried upping the ram voltage but i get a black screen at bootup.
i would also like to mention that with 166 ram and 232 i ran burn-ins HotCPU - this worked for 6 hours stable, but Prime95 crashed after 6 minutes! ive ran various apps to test the system and its seems happy .. left on for over 24 hrs running other stress testers and they seem happy to.
hope you understand my nonsense and the answer is simple (ie your setup is rubbish har!) seriously tho, i hope someone has had experience with this kind of setup and can shed some light here. just seems odd the ram wont go any faster when fsb is cranked up.
...oh just forgot to ask .. the P4VM800 manual states 2 DIMM slots .. 1 can handle 3200 and the other only 2700, is this correct or an asrock error .. ive emailed them but with no response.
asrock are correct when a motherboard says it can handle upto 2gb ram but as you know 1gb ram = 1024mbs so two of then takes it over the 2 gb that the board can support on pc3200 400mhz, it will support 2 gbs of the lower memory ie pc2700. or lower. also the motherboard you have runs at 800fsb and with your pentium it should run ok. going back to the unstable part it maybe that the thermal compond between your heatshink and processor may not be good enough, you have to cover the whole top of the processor to keep the temp down as I found out with mine.
