i am wondering how can i over clock the cpu in my Packard Bell Pulsar 21/H before someone says upgrade the ram 64 is the max it will take. There is nothing in the bios to overclock if it needs to be done by jumpers can i have the arangement of the jumpers as i am a newbie to overclocking! Thanks Martyn.S Merry Christmas And Happy New Year 2005

You shouldn't run more than 64mb in that rig anyway. You have to look at the board to see if the jumper settings are printed on it somewhere. If you're able to increase the FSB from 66mhz to 75mhz, that'll put your CPU speed at 262.5mhz (probably recognized as 266mhz)...if it won't run at that speed, you can try increasing the CPU voltage from 2.8v to 2.9v, possibly 3.0v...if that doesn't do it, keep the FSB at 75mhz & lower the multiplier to 3.0x. That will put the CPU at 225mhz. Although that's 8mhz, the higher FSB will more than make up for the difference. http://www.hwupgrade.com/overclock/cpu/index8.html Asus A7N8X-X 1800+ @8x210mhz 512mb PC3200 Ti4200/8X 128mb WDC 60GB

I meant to say, Although that's 8mhz less than 233 Asus A7N8X-X 1800+ @8x210mhz 512mb PC3200 Ti4200/8X 128mb WDC 60GB

I used to run a 200 mmx that I successfully O/C-ed to 233mhz. My guess is that there should be some jumpers on the left edge of the board thatyou can play with. However if your board is the same as mine ( a media runner I think ...) the that is as far as you can go :-(. There should be some info on your motherboard in the accompanying user guides. Raise the speed in SMALL increments are stress test using prime95 to check that it is totally stable. as for your RAM (again on the presumption that your board is similar to mine) 64Mb is the max for EACH slot, so I was able to have 128Mb as mine had 2 RAM slots. The RAM should be around £20 from crucial, if you cannot find it i will be happy to sell you mine for £10 + p&p. Happy O/C-ing! oh and try to ditch ME it is very buggy!

The problem with installing more than 64mb RAM is that you've probably exceeded the cache limit, therefore you'd be running off physical RAM rather than cache. Doing this will actually slow your system's performance. Staying within the cache limit is always preferrable, but running off physical RAM is faster than having too little RAM & using the hard drive (virtual memory). It depends on what you use your system for. Asus A7N8X-X 1800+ @8x210mhz 512mb PC3200 Ti4200/8X 128mb WDC 60GB

I have set the jumpers to set my cpu to 9V but its still at boot up is reconised as a 233??? Martyn.S

True. As I was running windows 2000 and star office 7, (both of which are quite RAM - hungry) I felt it made a noticable differance to the speed at which I could do things, it certainatly helped with web browsing, especially on pages with lots of images. :-p Merry Christmas!
