OC which first?

post #1 of 19
Thread Starter 
so i want to try and overclock my ram tonight. i have been doing plenty of research and found a few guides that explain how. so when i try and OC my ram, should i have my CPU at stock settings, or my current OC settings? will it make any difference?

Your computer's already OC'ed?

The point of overclocking each component individually (by leaving the others at stock or underclocking them) is to find the limit of each component.

The point of doing that is when you change your OC settings later (because you dare more, or changed a component, or added cooling), when you hit a wall you'll know which component is responsible.

It also shows you whether your power supply is powerful enough. My old generic PSU couldn't handle having every component OC'd, even though everything was tested individually.

yes, i have already OCed my processor, so i'm wondering if i should set it back to stock settings before i overclock my ram. if i understand what you are saying right, then i'm thinking i should.

Leave your CPU at stock and OC your RAM until it becomes unstable (go to the required voltage you are willing to give it)

After this OC your CPU and your RAM together so that they run together

Note: Always OC the CPU first to find its limits (put a big divider on the RAM so it runs at a low frequency) and then do the RAM. Then do both together and find the max stable OC when they are combined

TBH though, you don't even need to OC the RAM while your CPU is at stock. You can just keep your CPU at max OC and see which divider the RAM can handle at that FSB and then tweak the timings afterwards.

Yes, but if you "simply" do that you won't know which settings are better : a higher clocked CPU with a low RAM divider, or a lower clocked CPU with a higher RAM divider.

Not to mention that if you try each RAM divider with higher voltages on the memory (cuz you're looking for the best OC) you might fry your stuff...

once i get into this, what software can i use to benchmark so i know what settings are better? i use orthos for stress test, but that doesn't tell me anything about speeds.

Well you should never push your voltages to the danger of frying.

But that's why i mentioned the other one first. I don't like doing it that way either. But it is a quick way for someone to do it if they are impatient.

I don't really know many benchmarks. Except for Super PI.

Do a 1mb test on clock settings. Then at every stable OC you get, run it again and the time for completion should decrease

to oc ram, just up it til it wont bootup. start at 1000 with vdimm maybe 2.1 if not, then 2.2 and work your way up.

Even though its a 939 based methosd, the concept is the same for AM2, just take into consideration the DDR2..
