I have one more week of study and then end of semester exams are over. After that I am contemplating taking 6-12 months off school so we can hopefully expect more frequent posts for quite a while.
Are any of you building your own PC right now, or have some project constantly going? If you can get some nice snaps up on your tumblr i would love to see!?
You mean 8 cores at 5.0 Ghz is great for you ;) Get that thing OC’d!
If your not using your computer for just gaming then i retract all of my advice haha, you sound like you know exactly what you need!
I am a bit puzzled about your mobo not allowing higher memory speeds unless the CPU is overclocked? Are you sure this is the case? or is it just something to do with AMD chips that i have no idea about?
I see on the ASUS website they state ‘(OC)’ next to every supported memory option above 1600 but in my experience with intel chipsets that means the processor doesn’t support those speeds natively, but you can still run your ram at its spec’d speed to and not have to OC your CPU as well. Nothing slow about 1600mhz though :) will get better timings with slower ram also.
I cant really help with OCing sorry :(, as i only have experience with intel chips, but can say, don’t be scared, if your careful there is really no way you should wreck your processor, as long as you have adequate cooling, and make sure you know and don’t exceed the max safe voltage for your processor.
First we need to figure out how much power that power supply can supply on it’s 12V rail(s)! This is the power that CPUs and GPUs use so it is the most important when choosing a power supply. The Extreme 2 725W supplies 28A each on two 12V rails (x), (amps x volts = watts)
(28A x 12V) x2 = 672W
Your total system TDP (non-overclocked, and not including RAM, HDDs, etc) is going to be around 84 + (140 x 2) = 364W
This gives you about 300W left over for your fans, HDDs, SDDs (which use hardly any power), water pumps etc. TL:DR Plenty of power headroom for overclocking!! :D
The bloke is the shop either 1. is seriously uneducated/misinformed about computers and power supplies (needs a new job) or, more likely, 2. was blatantly lying to you so you would buy a new PSU.
EDIT: I originally called TDP ‘total power draw’ which was a terrible mistake i am surprised no one pulled me up on o.O TDP stands for ‘thermal design power’ which is the maximum amount of power that needs to be dissipated by the chips cooling system.
Hey thanks for the question and compliments on the blog!
You said this is going to be your ‘first custom PC’ so i am assuming you don’t have any of the parts yet? If so this would be my advice for your build:
1. Processor: Is there a particular reason you want to go with AMD? If you don’t have your mind set on AMD for a proc for any reason except for price, I would recommend paying the extra money for an i5 4670K. Just check out some benchmarks and make your own decision on that but :)
2. RAM: 32gb is unnecessary for gaming, so if you don’t need it (you might want it for some other computing) i would get 16gb at a higher speed.
3. GPU: I know 7950s are cheap as chips now, and running 3 cards is going to look awesome, but factor in the extra power usage, the fact you will need to buy an extra waterblock ($100+) and the fact that performance does not scale well with more than 2 cards in crossfire x/SLI before making a decision. 2x 7970/280x cards may save you money for almost as much performance (will only need a 700-850W PSU also). I would also consider going for a single 290x (probably not the best idea if you want to run 3+ screens straight away) and sticking another one in later if you have the money!
Keep in mind, that’s just what i would do if i was building a system, if you want to have 3 cards in x-fire go for it, and if you really want a AMD cpu that’s fine too.
If you are from the US here are some online retailers:
I cant recommend any except side winder computers, who i ordered from early in the year with a great experience.
Also DazMode in Canada is awesome
I have no idea about Europe or the rest of the world sorry!
If you have any other questions feel free to ask, especially if they are about water cooling.
