well hi everyone this is my first post but i already have some time reading the forums , my english is not very good and well... this is my current system
-core 2 duo e6400
-2gb ultra ddr2 533 memory
-xfx 7900gt xtreme edition overclocked to 612/961
-160gb ide seagate barracuda 7200.9
-cooler master aquagate
-agiler 800w psu
the problem is that when i overclock up to 2.8 the computer starts to perform very poorly on some applications and better in others , for example sometimes just opening a file puts a 50 % load on the cpu and opens it very slowly but when i run super pi 1M my times drop to 19 seconds, computer is orthos stable. so i dont know if that is caused because im pushing that crappy ram too far (i had to buy it because that was the only one available ) or is the motherboard that is making the computer perform slow on some apps or is the hard disk i really dont know
so if have to upgrade ive thinking about asus p5n-e sli , or a 74 gb raptor or 2gb of ddr2 800mhz ram (maybe corsair or something similar) i want to overclock higher without those problems mentioned above and i just can afford 1 of those upgrades at a time so wich upgrade should i pick or what other options do i have to consider?
If you want to OC further then its probably the ram thats limiting you though I dont see why you are having problems with that cpu?? It should open up files instantaneously so your problem is not the cpu! Therefor I wouldnt bother throwing away 2gb of ram just to get a slightly better OC. Your cpu is fine and 2gb ram is also fine. I would save your money for the futur when youll need them honestly!
Also if you want a performance boost without wasting money then get another HDD and raid0 them. That should help for basic performance like opening files!
