Good instructions to follow regardless of the brand of compound you use... http://www.arcticsilver.com/pdf/app... I'd be looking for idle temps in the 30's and full load temps in the 60's for a Northwood B; higher if it's a Prescott core. Let us know what the sSpec number is on the processor; 5 digits starting with "S". Skip

im sure it was sl6pf but i may be wrong.....

got it its sl6hl

To put it in perspective, you can buy a reasonable spec P4 478 3000mhz (Hyper Threading) Tower for £60-70, I sell them with 15" TFT monitors £90-100 (also sell Skt754 3000+ for similar dosh). http://www.friday-ad.co.uk/AdRef/YI... Anything older than 1996 has had it day when it comes to upgrading economically.............. ie thats Socket A / 478 / 754 / 939

2e0saf, You need to understand a few things about your system. The P4 is a highly inefficient CPU. One way to partially make up for that inefficiency is to run the RAM at a higher frequency than the CPU. For CPU's other than the P4, the optimal CPU:DRAM frequency ratio is 1:1, but for the P4 it should be either 3:4 or 4:5, depending on the base frequency of the CPU you're working with. In the case of a 533MHz FSB P4 (133MHz freq), you should be using the 4:5 ratio. That would put the RAM freq at 166MHz (DDR333, aka PC2700). If you were to get an 800MHz FSB CPU (200MHz freq) to pair up with your PC3200 RAM (200MHz freq), the ratio would be 1:1. Your system would perform better due to the FSB increase from 533 to 800MHz, but it wouldn't perform optimally because the ratio wouldn't be optimal. You have to look at the BIG picture. You have a board that's based on a VIA chipset, a 533MHz FSB CPU & PC3200. So not only is your system obsolete, it's poorly configured. The saving grace is that both the 2.8GHz Northwood & your board are highly overclockable. So rather than wasting your money on a new CPU, why not just overclock what you have & optimize the settings at the same time? But before you proceed, you need to get the temperatures under control. The board of 41C is high...what is your average room temp? And 85C for the CPU is extremely high...you're at the point where the CPU will begin throttling. Where are you getting these readings from...software? Check the BIOS. I suspect those readings are incorrect. http://processorfinder.intel.com/de... http://www.asrock.com/mb/overview.a...

jam i forgot to mention the temp readings are the same in the bios as well...!!! cheers

I didn't need to know any of the above....I already know your system configuration. What are you temperature readings from the BIOS?? Apparently you're not into gaming? If you are, you made a poor video card choice. EDIT: I see you posted about the BIOS readings while I was responding. But I did spot something wrong in your settings. You're running the CPU at 133MHz & the RAM at 100MHz? And the ratio is reported as 3:4. The ratio would be 4:3. In actuality, the CPU should be at 133MHz & RAM at 200MHz with the ratio reported as 2:3. I don't know if you're copy/pasting that info or you're keying it in, but something's definitely wrong. And if that info is correct, your BIOS settings are a mess.

so how do i get the cpu and memory to read correctly.... yes just copied an dpasted from everest program..!!

i made a few changes in bios and now getting this reading...!!!

and this is the readings i get with the memory set at 200mhz ddr400 and auto cpu setting 133mhz Field Value CPU Properties CPU Type Intel Pentium 4 CPU Alias Northwood CPU Stepping C1 Engineering Sample No CPUID CPU Name Intel(R) Pentium(R) 4 CPU 2.80GHz CPUID Revision 00000F27h CPU Speed CPU Clock 2800.1 MHz (original: 2800 MHz) CPU Multiplier 21x CPU FSB 133.3 MHz (original: 133 MHz) Memory Bus 200.0 MHz DRAM:FSB Ratio 6:4 im now not sure what else to set up...!!! cheers for your help jam.... p.s. where are you located

Normally the ratio is given as FSB:DRAM in which case the proper ratio for your setup would be 2:3. Your ratio is being reported in reverse - DRAM:FSB - so it should be 3:2. Regardless, you now have it right at 6:4 which reduces to 3:2. I'm in western NY.

great so how do i over clock the cpu... or would still benefit from buying a better cpu i can get a 3.2 800mhz fsb northwood reasonable price... SL6WG or would a prescott cpu be ok i believe they are power hungry tho and someone did mention to steer away from those cpu's cheers again... im in uk jam i was actually going to give you my phone number to call if you were in uk however any help would be great... regards sean...!!! also if you have a better solution like replace the complete main board i would consider this if you cold give me some idea's i use ebay.co.uk and they do quite a few bundles on there fairly well priced maybe the same form factor tho would be a bonus..!!! cheers

I'll download the user manual for your board & get back to you with some overclock suggestions a little later. Hang in there....

ok jam thank's regards sean

Doesn't this board have Untied OC Technology where the pci-e and pci busses are locked? Turn off any Spread Spectrum settings in BIOS and just start bumping up the fsb from 133Mhz. 3-5Mhz at a time would probably be safe. Keep a close watch on cpu temperatures. You can test for stability with a program like SuperPi. CPU temps for a P4 will have a large variation from idle to full load. Don't be alarmed if you see 70°C when running SuperPI. http://files.extremeoverclocking.co... You will run into a wall somewhere...we just don't know when. 142 or 143Mhz will give you a 3Ghz machine; 152Mhz would be needed for 3.2Ghz, and so forth. Don't get in a big hurry and a notebook of your changes and the results will come in handy. Skip
