ram and cpu

hello all!!
im fairly newish to overclocking but ive learnt quite a lot so far and wanna learn more!!!!, i was hoping to get some advice from people who know what their doing

. I really only use my pc for games, but wasnt sure if its better to sync my fsb and ram and get a 1:1 or the tighest i can get, or just go for a high ram overclock? or change my cpu multiplier to get higher fsb? so if any one could help i would really appreciate it!!! thanks!!

atm my set up is:
e8400 @ 3.6gz (400x9) 1600mhz
gskill pc2 8500 @ 1280mhz
fsb 5:8 dram 5,7,7,20
mobo p35 ds3r

Thats a good standard overclock which is perfect for stability and performance. What are your temps like, particularly on load?

In terms of getting everything in sync, you ideally want to try and match the ram as close to what its rated too, ensure your voltage is correct for your memory and set the timings to "by spd" and double check them once in windows using cpu-z.
PC2-8500 = DDR2-1066mhz so based on your overclock you want the memory set to ddr1000 in the bios with a ratio of 2:5.

thanks for the reply, idleing about 44c, load 50c, from what ive read e4800 have doggey sensers so dont know how trust worthy they are lol! over the weekend ive been mucking about with my memory so been changing the timmings etc and found out what my ram was supposed to run at 5.5.5.15 @ 2.1v to give me 1066, but was just seeing how high i could get in hense the 1280 atm lol! but then that got me on to is it worth going that high and does it aid performance? but im guessing for gaming i want to have tight timings! but ill try what you said! thanks!

yeh, optimum is at it's rated speed and timings. But if you're overclocking the ram you'll need to either loosen the timings, up the voltage, or both. Temps seem good but you'd normally expect a bigger difference going from idle to load. What cooler you using? Use prime95 and run for 5 minutes and check the temps to check load temps.

Also, you mucked about with the cpu voltage at all or anything else?

You can use the cache and memory test in everest to check your memory performance, then try drop the speeds down and tighten the timings to see if there is much difference.

Real world difference will be tiny and only tests like this or super pi/wprime will highlight the difference. You will never hear that overclocking RAM added on 10fps but might shave a few seconds off a benching run

that seems a fairly solid OC... i would suggest leaving it where it is and have a play with the "Search" button found ^ up there.
