i need a little guidance with overclocking

[Smirabi]

i hope this is in the right section...

ok, well when i first understood the basics of overclocking (i knew very little, but enough to squeeze out some extra mhz) i went ahead and did what you see in my sig. but it was achieved by 180*12.5, which isnt as good as a higher fsb and lower muliti.

so last night after reading guides on overclocking (found in the cpu, mobo, and general hardware sections), i decided to lower the multi and slowly raise the fsb until i reached the highest stable fsb.

so my question is, how low should i put my multi for this process? i ask because i put my multi at 7.5 and my fsb at stock166, then as soon as i raised the fsb to over 170 i got the post "system failed memory test" or something like that. these asus boards are notorious for saying "system failed memory test" and still booting up fine. so what should i do?

1. should i have it "halt on no errors" instead of "halt on all errors"
2. should i try a multi of 8 or 9 instead of as low as possible (6)?
3. at what steps should i test for stability, only fsbs past 170, 175, 180, etc? (and using which programs? prime95 is good, right?)
4. "by SPD" means 1:1 fsb to mem, right?
5. how should this (fsb:mem ratio) setting be adjusted during this initial process of determining the highest stable fsb? one of the guides addressed this, but i kinda want other opinions.


i understand that the answers might be out there already, but i did put quite some effort into finding a real comprehensive guide that addresses the questions, and i did find a great guide in the mobo section, but i still have these questions.

thanks in advance

1. Its up to you. I have halt on no errors.
2. What ever you can run to make the FSB as high as possible and the overall speed as high as possible. You need to test and try both to determine the best for your configuration.
3. Prime95, MemTest86, Toast, F@H/S@H start high and work your way up 5mhz at a time until there are issues, then back down 1mhz at a time.
4. SPD refers to the SPD module on the memory chip to set the DRAM timmings according to memory speeds. The MB divider should be set to 1:1 on all AMD MBs.
5. On all AMD MBs you should always run 1:1 CPU:MEM

people run 5:4 when they have slower ram

[skitlets]

5:4 isnt very beneficial when it comes to amd boards, maybe intel, but im not sure. try to keep a 1:1 ratio, and if u get those system failed memory tests errors, just run prime95 or memtest to determine if your memory can actually handle those speeds or not.

AMD and especially nForce platform performance will suffer with anything other than one-to-one memory:FSB ratios.

thanks a lot guys, i appreciate your time/effort

true captain, which is why im upset i bought pc3200 =/
