New to overclocking with questions.

Recommended Posts

I am running a crosshair z with an 8350fx processor. I have 12gb of vengance 1866 ram. I was using 16 but one stick is dead.

Would that ram work to do a mild OC? Also if a board lists ram as compatible with the speed and OC in parenthesis does that mean you have to overclock to get that speed out of it?

If that ram isn't favorable for an overclock what would you reccomend? I remeber reading that more bandwidth is better for AMD systems.

Not sure about the FX chips doing well with more bandwidth but i know the APUs absolutely LOVE high RAM clocks.

 

One thing I've always experienced with RAM is that the majority of the time, RAM is usually good for one clock higher - i.e. 1333 => 1600, or 1600 => 1866, etc. May need some voltage boost though. 

 

Usually bracketed clocks is an OC clock.

 

I've not much experience with RAM overclocking to be honest, usually I do CPU clocks and that's about it, RAM clocks are generally pretty minimal in 'seat of the pants' performance. Important for benchmarking but that's a different world.

Thanks for the info. I thought that to OC the processor you had to tweak the RAM a little bit. Too bad I can't find a cheap system to play with to learn.

I have an FM1 rig setting around but its an A55 chipset.

I've never had to touch the RAM clocks to OC an AMD CPU :) AMD doesn't link all the clocks onto one bus like some of the Intel systems. In fact right now I'm running a 3.2 => 4ghz overclock on a K10 Phenom and i haven't touched voltage, RAM clocks, or PCIe bus clocks. Nice and stable.. Need to get it under water so I can crank the clocks up to the max :D May try bumping the RAM up a clock bracket when I do that just for s**ts and giggles.. 1600 => 1866 :)

Cool to know. I'm crossing my fingers to be done working on my computer from an assembly perspective. Then I can toy around with overclocking and hopefully find the "for dummies" version of it all.

as long as you wont go nuts in voltage section of bios, and keep it cool ;) playing with oc is quite safe. Couple of bios clear procedures later you will know way more ;)

About RAM. In day by day usage you don't need to touch it. Not only leaving ram in default settings won't add to your list of possible stability problems but also you won't see any noticeable impact on performance. 

 

Also, some memory sticks won't work at their listed speeds. Some sticks with some mobos need to be set to what your box says. Good example are hyperX khx1600 @ some z77 boards. When installed they will word @ 1333Mhz and you have to put them at 1600... does not mean you OC them. So just check if cpu-z show the same numbers as your ram box ;)

    There's a thing here. Somehow it moved to the top of the page, but I didn't do it. No, really! But still, Cheaps is likely to blame...
