MSI REWARDS - PARTICIPATE ON MSI FORUMS, GET REWARDS
Originally posted by Saint I have a Athlon XP 2000+, MSI K7N2-L, 1x 256Mb crucial Ram, Geforce 4 MX 440, 20 GB Samsung HDD, AOpen CDRW. My question when I tried to up my CPU multiplier from 266x 12.5 to 266x 13 machine would not post. Am I looking in the right place to O/C or should I start some where else?Thanks
Originally posted by Robbeh To alter the multiplier youve gotta unlock the chip first. Do a search on google for the "wire trick". However loopyloops is right upping the fsb to its limit will give better results and needs no modifications.
Originally posted by brummieman OH..was a waste of time me saving that pic of the trick then LOLThis 'painting the bridges' , I assume its conductive material, what do you paint and between where ? ) Also another question :I have overclocked my XP 2000+ using the FSB, I got it up to 144mhz, but then noticed random reboots etc, i have slowly stepped down until now it is stable at 138MhZ.Question...what is the likely cause of the reboots higher up..I gather many get upto 144 stable. Is it the memory, and if so what are the best stable settings for the memory (2700 CLR2.5...currently I have it set to 'set by SLD' whatever that means) :] thanksBrummieman
Originally posted by brummieman Thanks for the help..the video of linking the L1 bridges was instructive..but not sure I fancy that trick..looks a bit messy LOL, especially as the bios only allows a multiplier of 13 max so dosen't seem a great leap from 12.5.I will look for a t-bird at some point I think....but still not sure about the memory settings ?When I raise the FSB, am I forcing the memory to speed up aswell, and should anything above 138 MHz be a problem for 2700 CLR 2.5 memory ?ThanksBrummieman
Originally posted by brummieman Well ..now running at 142 MHz FSB (1.78 MHz Chip) and so far seems to be stable....seems the 1:1 memory timings did help. :D Thanks
Originally posted by Robbeh Running the ram at 333 not sync is slower than 266 sync. For the best performance youll need to lower the multiplier which will let you raise your fsb to 166 and beyond.
Originally posted by lowrider87 loopyloops,Quite a few of the reveiws that came out when the nF2 first came out, said Sync was the fastest. Myself I have crappy PC2100 in my comp and I am taking a hit on performance by running my ram at 75%. I am doing this only to get to 200 fsb with out crashes. To get the best performance it should be run at 1:1 when overclocking.
To get the best performance it should be run at 1:1 when overclockingThat's the ticket!
But I'm correct when I say that at default levels, ram going faster - 2:3 - would give better performance than, say 1:1.

With present bios and setup all NF2 boards run at best performance when run 1.1 FSB/DRAM. It does not have nothing to do with overclocking. QuoteBut I'm correct when I say that at default levels, ram going faster - 2:3 - would give better performance than, say 1:1. This is going to have alot to do with cpu/ram configurations.For example someone running a 200fsb duron and 3200 memory....then yes I would say 2.3 would be better for overall performance......But an XP or Barton should be set 1.1 with the same ram.Hopefully future bios updates will help the issue.
Originally posted by Robbeh loopyloops, running your ram at faster speeds than the fsb adds latency, slowing down memory performance ( I read somewhere it results in data from the ram being cached while the cpu catches up). This is why upping the fsb to run at the ram's rated speed gives such a big performance boost
Originally posted by lowrider87 loopyloops,In my bios I have the ability to set my ram usage. I can run in sync or set it manually to what I want. I was having problems at the 200 fsb with crashing or not posting. I set my ram at 75% which set me at 150 mhz instead of 200 mhz in sync. This helped me out considerable on the crashes. My PC 2100 did not like the higher settings. I could only get as high as 170X12 running 1:1 with the ram.
