How much difference with divider

Gaygle · 16 Jun 2006 at 11:23

Hi i was wondering how much difference is there in performance if i run my memory with a divider. i currently have it at 215mhz 2:1 but when i had it on a divider before, i had the CPU up to 235mhz (from a 3500+ newcastle and still had more) and 186mhz from the memory at 2.5-3-3-7.

any help is welcome

thanks

No performance hit if you use a divider to keep your memory at its rated speed

What have these tests proven? They've proven that overclocking your K8 system while using a memory divider to keep that cheaper DDR RAM within spec is nothing to be ashamed of. We saw quite healthy gains in all departments, including memory bandwidth, merely by raising the CPU clock even though we kept the memory at ~200 MHz at all times. I repeat: You are not a weenie if you use a memory divider.

On A64 CPU speed is everything in terms of performance, using a divider has little or no performace hit, especially if it means getting more CPU speed. I had to battle this out with someone a week or so back and did some quick tests to prove my point:

lol, good one mate.

A lot of people on this forum don't understand this. Every week in the memory section you see someone asking for high speed RAM for overclocking and you just think to yourself, what a waste of money. PC3200 RAM with tight timings + divider is all you need.

3500 with tight timmings is a safe bet if you want to overclock as you dont really want to keep the mem its rated speed if performance matters. with 3200, you might endup forced to lower latencies or drop the divider further taking the rated speed far away from the mems actuall rating. 1:1 at lower lantencies and 2t is an option also but thats worst performance by a measurable ammount.
