My Specs:
i5 4670k
PowerColor Radeon R9 280X (3072 MB) (AXR9 280X 3GBD5-DHE) Graphics Card
corsair RM1000 1000w gold fully modular Power supply unit
evo 212 cooler master CPU cooler
Asrock z87 Extreme 3
Western digital caviar blue 7200rpm 1tb
Galaxy 3 Gaming Computer Atx case
Corsair 8GB (2x4GB) DDR3 1600MHz Vengeance Memory Kit CL9

im basically looking into overclocking my CPU before possibly upgrading my GPU in a month or two, firstly i wanted to know if this looks about right for my overclocking as i am pretty new to it but been reading up for a few months and just finally decided to give it a go, but i noticed it said ram was 1500 and wondered if maybe i should be changing something for it to run at 1600 and wondered if thise made much difference also.

lastly i wanted to ask if anyone had any simple advice on upgrading the PC, im mostly thinking graphics at the moment, i also wondered if doubling my ram was a reasonable idea as originally the PC was built for gaming only but ive started using it for video editing now also, so yeah general advice on the upgrading front would be lovely, thanks :)
 
Solution
1.240V then :).

You may be able to run the chip up over 1.280V. Well just have to see how well it runs.


Once you get it stable, thar are other tweaks to reduce the voltage and/or to get the idle voltage down toward stock.
If you are using Prime96 for stress testing, make sure it is version 26.6. Anything more modern can be dangerous for Haswells.
That looks good. What is your idle temperature? The Vcore is modest and your temps look good. You can safely go for more if you want to.

RAM 1500?? could you show us where it says that? Video editing will benefit form more RAM, and I would consider faster RAM too. RAM can be overclocked and you should be able to run at 2400Mhz. This will have a measurable improvement on your editing and a little improvement in gaming.

You have good, balanced parts, and an excellent PSU. I might want a better cooler if I were trying to overclock above 4.5Ghz. There is no part that screams 'REPLACE ME!'

The cheapest significant improvement apart from memory, would be to Crossfire another 280X bought second-hand or refurbished.

I would wait 18 months or so before doing much else, unless there are some games that are REALLY frustrating you, and even then I'd consider turning the wick down a little to get playable frame-rates.

Thanks for the reply, i wasnt sure that info would give enough to make a judgement on but glad it was, idle temps are around 38 to 42 but im also using an external cooler setup with decent airflow in mind (had a friend set it up for me) how far would you push it yourself with an i5-4670k if it where you? obviously id do it in increments but ive only stopped due to it doing what i needed for now.

sorry it was the Dram 1.500 i should have looked closer, its because in the bios my ram has an option for 1500 default or 1600 with xmp profile set, i thought so but due to never really doing much editing on my home PC i really wasnt sure, would there be MUCH difference between 16gb and 32gb in terms of editing and in terms of gaming? ive always been under the impression that for gaming go with what games are requiring and for editing go as high as needed really, is overclocking the ram pretty easy? i was reading up on the difference between mhz in ram and i couldnt really understand what areas of PC usage it effected hence asking haha

yeah im already planning on it but thanks, i just got done comparing alot of newer 4GB R9 290x cars but crossfire seemed to outperform them all on 90% of games especially the ones i play myself, but glad to have someone backup my first thoughts on that one

yeah ive just hit the point where im thinking "some games seem to really be pushing the limits right now wonder whats in store over the next year or two" to be honest with my setup right now and overclocking the card a little im getting around 80fps on battlefield 4 on ultra so im pretty happy, and with GTA5 im getting a pretty decent 60fps on pretty most settings on full (obviously stuck at 1080p due to the card but im happy with it as my projector is also only 1080p anyway) but id love to get a bit more push for GTA5 to keep the FPS a bit more constant

thanks for the help, hopefully i can maybe push the CPU a little more then, ive tried before but i kept getting alot of crashes after half hour or so of gaming so dropped it to 4.0 just because it was stable until i understood enough to really give it a go (i only understood the basics of overclocking and just had to go step by step when i started, so thought id stay safe till i really understood the voltages etc)
 
38 to 42 is a high idle temp. I'd like it close to 33 average.

I'd do a bit of experimenting.

Take off each one of your removable case panels, one at a time and see if it has any effect.
Get another case fan (or borrow one) and zip tie it to different places in the case and see of that helps as you move it from place to place..
Rotate your CPU cooler 90 degrees.

This should help you identify where cooling can be improved.


16 or 32 GB will have almost no effect on gaming and in my tests over the summer, I found that more memory slightly slowed many synthetic benchmarks.

More memory will help with editing because more of your work will be in RAM.

Getting a good 240Gb or greater SSD makes the system feel a lot better.

i just rechecked the temps and they seem to be sitting around 35 now but ill keep an eye on it to make sure it stays there

will do, any advice on voltage settings you can give me? ill end up doing alot more re-reading before i give it a go anyway but thought it was worth asking

i already have the left side panel off anyway, its actually off most the time but i tend to clean it once a week because of this, i couldnt use the side case fan though as its built into the removable panel, i also have a fan almost half the size of the PC providing more airflow, if it easy to turn the CPU cooler? my problem is i think the ram is in the way of the cooler as the cooler is pretty big in my case.

thanks again, ill play around with and keep an eye on the temps and see if it changes, hadnt through of trying that such a simple idea too, dunce moment haha

so maybe just go with 16gb for now then to speed up editing and not effect gaming too much?

already on it haha again glad to know im heading in the right direction, what do you think of this SSD?

That's fine, although I'd get this http://www.amazon.co.uk/dp/B00P736UEU/?tag=pcp0f-21 better and a couple of quid more.

I'd run the Vcore up to 1.24V, keep the clock, and see what the temperatures are like. They should be fine. Then step up the multiplier until it fails 10 minutes of OCCT. Drop back one step and do a full stress test and tweak the Vcore up or down as you can or need. Depending on there you get to and the temperatures you may be able to go further.

cool thanks dont mind spending a little more to get a little more, and id been reading the first SSD i chose was slower than most around the same price so i knew id need to ask to really get a decent one

i know this will sound like a silly question but when you say 1.24V which ive been reading alot when reading up, how is that actually typed into the bios in terms of numbers seeing as its 4 digits like 1.025 where does the zero fit in if that makes sense, ive read so much and its the only thing that throws me off, probably mostly because i dont want to be doing it wrong with the voltage and messing things up for myself haha, better safe than sorry so to speak

ok cool thanks, i had it running at 4.2 quite well at one point using default overclock settings in the bios but it wasnt always stable, hence deciding to read up and do it all manually as i knew it would be the best route, thanks again, ill select your next reply as solution as i think ive gotten everything i was hoping for, thanks again your a legend.

cool thanks, i knew it would be 1.240 or 1.024 but as much as i guessed right i dont like working on guesses haha

ill give it a go then an message back once im getting somewhere see what you think.

ah ok ill remember that, originally i used a few programs suggest on a few threads but ill stick with that as it comes up most

one thing i did forget to ask was any chance you could suggest a decent 2500hz ram to consider?

heres a list (dont worry i do shop around for best prices though haha) http://www.ebuyer.com/store/Components/cat/Memory---PC/16GB?a00486=2400MHz&sort=price+ascending

Hi again, hope its ok to reply in this thread, i wasnt sure if youd be alerted about replies or if i should start a new thread but thought id try here first, but i went ahead with trying 4.2 just wanted to see if this is right and if it looks good

i set the multiplyer to 42
left the cache at 38

i set the vcore to 1.240 and changed it from adaptive to override as ive read alot of people saying not to use adaptive

i left the memory option on auto because id tried performance mode but it wont boot, also says it can be unstable
i tried setting it to the XMP profile which is meant for 1600 rather than 1333 but it didnt work so set it to auto again and left it

i used the version of prime you said to and so far temps are sticking around 63 highest its hit is 69 thats using blend mode

wondering if this looks good and is right, also wondering about testing 4.4 (which is the highest i really wanted to go for now anyway) and wondered how do i go about lowering the voltage from that point on, either after testing 4.4 or from 4.2

The best RAM is Mushkin Reline ( the Ridgeback heat spreader) which uses Hynix chips. I can be overclocked beyond 2400K. A parent donated my memory or I would have bought it.

I use G.Skill Trident X and have overclocked it to 2600Mhz, but the performance gains were marginal, so I dropped back to stock.
 
If 4.2 is stable, try 4.3. Or set the multiplier to 44 and see what happens. If it does not boot, increases Vcore by 0.005V and try again. Rinse and repeat until.

a. Stable - good
b. Voltage exceeds 1.350V - nearing 'voltage wall'
c. Stress temperatures exceed 85C. - nearing 'thermal wall'

We are doing a SIMPLE overclock, using only Voltage and Multiplier. When we know what we have there are numerous other BIOS settings we can tweak to tune voltage and temperature. Overclocking up and changing ten or twenty parameters is mind-bogglingly complex for a first overclock, so we start simple. This is how I do things with my Middle School students. Once stable, they can change the other parameters and see the effect that they have on the overclock.


To get to 4.8Ghz, I had to run my memory at 2400Mhz.

so this memory? or can i probably find one with even better timings? as ive seen alot of various types after just a few minutes looking

http://

and thanks for the info i will give it a go then tomorrow and get intouch if im getting somewhere with it, should i probably wait till i get my new memory before going for anything above 4.4 do you reckon? or is it worth just giving a go anyway?

well i have to admit im not surprised you teach, uve made everything amazingly clear so far, im usually having to ask alot more questions when it comes to overclocking haha

http://www.tomshardware.com/forum/id-2626627/build-log-middle-school-science-fair-project-system.html

Here's some of our school systems.

That Mushkin Redline is about the best overclocking memory available as long as they use the Hynix chips. I used G.Skill Trident X because a parent gave me a set of 2 x 4 and a set of 2 x8.

I did not need to go to 2400Mhz until I got to 4.7Ghx, and it booted at 4.8Ghz, it was just not completely stable. In addition, some of the parameters you change after you know where you are at can improve memory stability.

I would not upgrade my memory until I knew I needed it. You should be able to get to at least 4.6Ghz on what you have.

ok thanks, would it be worth me upgrading the memory still due to me now using the PC for editing aswell as gaming or worth just seeing what happens if i make it to 4.6 first?

im running at 4.4 at the moment, only problem i had was when i was gaming playing new call of duty crashed after about an hour but i believe that may be due to the slight overclock i did on the graphics card, so ill try again but without the GPU overclock

i tested it with prime ofcourse and this is what im getting

4.4
1.240v

small FFT 78*c
blend 68*c

the small FFT wasnt at 78 for the whole test ofcourse but i posted the highest temps rather than the temps they mainy stuck around just to get the best idea of where to go from here, i also tried lowering the voltage by 0.005 but it crashed during windows load screen
