edit: i just tried Prime95 test because x264 seem a little easy to pass and I wanted to see some fails XD. edit2: started to run 30+mins x264 on 47x@1.3Vcore 1.96VRIN. Already hitting 72*C so I guess if it pass the test I will kinda stay here. Don't want to push temperature any further | ||

I just completed some 40mins x264 on 46x@1.25Vcore 1.85 VRIN actually. Now will go on to test 1.95VRIN If it worked on 1.85 you don't have to test again. 72c peak during x264 is pretty cold still. No reason not to pass it and tweak to add a comfortable amount of voltage. 1.3 bios = 1.32 at some loads. If you have to set 0.03v higher (bit extra to pass an overnight and then safety margin) for 1.35v at some loads then that's fine, and you probably wouldn't want to go the next 100mhz up (for 4.8ghz@~1.42v) anyway. Depends what 4.7 takes but looks like you have stuff good and comfortable to me. Intel doesn't mind giving 3 year replacement warranties on 4790k's which can run around 1.3v and sit at >90c on the stock cooler in x264. There's also an OC warranty that you can purchase within 1 year of the CPU that costs $20 for i5, $25 for i7 where you can admit to doing literally anything to do with CPU OC, set 1.7vcore etc and they'll replace it anyway. Really the only thing to worry about with temperatures on such an OC is slow degradation coming because of temperatures and voltage. At 1.35v and 80c it wouldn't worry me unless i was running something like folding@home 24/7 on the CPU (in which case i'd use a different OC profile). Running Folding@home at 100% CPU load for 24 hours a day is very different from running something like WoW (at ~30% CPU load average across 4 cores) for 6 hours a day - that's over 13x as many "load hours" placed on the CPU, likely at a significantly higher temperature because of the simultaneous load. Degradation is down to voltage (most important) and temperature (bad to have high voltage and high temperature combination, particularly around ~90-100c - but not as important) multiplied by load hours. @1.34vcore, 75c peak in encoder for a gaming/streaming system, i don't think it's scary at all. If you want a system for those 24/7 loads like folding@home or mass mass video encoding and you want to run it for 5 years without worry, going back 200mhz would be fine :D | ||

Anyway just passed 1hr x264 test 4.7x@1.3Vcore 1.95VRIN with peak 72c. About uncore/ring/cache ratio, I guess I will try to push it up a little bit from current 33x, although from what I read from the guide it doesnt make much difference. Also, for RAM, current setting is 1333@1.5V. Do I just enable XMP to get it to 2133@1.65V and then stress test again with x264? A reason I tried Prime95 because it's said to test RAM stability as well. Still quite unclear about this. Again, thank you so much for helping Edit: usage-wise, this PC is just for playing SC2 and HOMM. My friend is not a hardcore gamer, so I dont have to worry about 24/7 loads, unless he torrent stuff which I doubt will have any significant load anyway | ||

now that you mentioned the load voltage, I just realized that Vcore reading is about 1.308V during x264 test. A lot of software reads VID and not vcore, labeling it as something like "core voltage". As far as i'm aware, CPU-Z was never updated to work properly with many Haswell boards for that voltage display, mine included. For mine (gigabyte z87x-ud3h) the correct voltage display is listed as "vcore" in hwinfo (www.hwinfo.com) if you open the sensors tab and scroll down. The sensor display isn't particularly accurate (it rounds a bit) so you can assume it to be 20mv (0.02v) above bios value at peak, because that's the voltage regulator behavior. You should be able to just enable XMP, but it's best to give CPU OC a bit of tweaking, safety margins and time to be sure that you're not introducing instability. Same for the uncore - RAM is more important than uncore for performance though, so go core, RAM, uncore. np, throw me a pm if you wanna add me on skype~ (good to write this stuff on a public forum anyway so i can be lazy in the future and say refer to post X-Y on page 484-485  )I do use prime95 at low CPU core clocks (like 3ghz) with a custom blend (using 7000MB of my 8GB of RAM) for RAM testing during RAM OC, but you shouldn't need it for enabling XMP. It will either generally work perfectly or it won't and you'll have to tweak something | ||

Trying to add some margin for Vcore now, may be 1.33 or 1.35V, another 1hr x264 test and then enable XMP i guess. What other tweaks for CPU OC can be done? edit: also pm'ed | ||

I'd try to pass ~20-50 loops then increase by 0.02 after that there's not much else for CPU OC, most of the minor settings are only important when doing very aggressive overclocks | ||

Salvageable parts (?) 2x2 Gb DDR3 G.Skill PC12800 1600MHz (Probably better to just buy 2x4 Gb with higher Hz i guess ? DDR4 worth it atm ?) WD Caviar Blue 640 Gb 7200t/min Corsair HX520W Xigmatek Midgard Samsung P2350 What is your monitor's native resolution? 1080p Can probably add a new one tho. Why do you want to upgrade? What do you want to achieve with the upgrade? Proc outdated (Athlon II x4 620), dead-end motherboard, GPU dead. I want to play HoN, Sc2, some shooters with good quality and framerate. Need an OS since i don't have access to MSDNAA anymore. An SSD would be a huge upgrade too. Don't know if i will bother about OC. Not Interested in SLI / CrossFire. What is your budget? Around 1000E but it is more expensive in my country. I just want the best bang for bucks. Don't want to pay premium price for a slight % of extra performance. What country will you be buying your parts in? France. | ||

You should plan airflow a little bit in your case, which fan slots you want to fill and which fans you will use there. You have an mATX case selected (small size) but full size motherboard, it won't fit. 980 is bad price/performance, 970 is much better there. If you're getting 980, it's probably something like a 1.6x price premium for 1.2x more FPS (with ~14% more VRAM) - you can check the price difference yourself~ they're the same thing, but the 970's are partially disabled to have a bit less performance and higher yields. While "bad price/performance" is an argument that you can make against a lot of high end hardware, i feel that it's particularly deserved against the 980 (given that 970 is so close with a vast price difference). It doesn't really apply nearly as much to the CPU, because that CPU is similar price/performance to the 4790k - and ~80% faster for multithreaded work than the 4690k, the next option down - it's a completely different tier product. | ||

I've gone back and forth about whether to get 970s in SLI or a 980. The reason I'm leaning towards 980 is that I'm worried two 907s won't be enough for 4k HMDs when VR gets going. Would two 980s be enough to power a 4k HMD? Should I go with 970s for now and then upgrade to totally different cards in December? | ||

IMO you should get one 970, run at a decent OC and allow for a second one. You can either grab a second one when you want/need it or get a much better GPU soon. If you spent the ~60% more on a 980, it's much less expendable. AMD is supposed to be releasing a card around august-ish-maybe targetting Titan X performance levels. At that point, Nvidia will very likely sell the Titan X GPU (gm200) as a "980ti" or something similar at a far lower price point, much closer to where the 980 is now. That GPU is ~50-80% faster than a 970 (depending on the OC you achieve and how extreme of an overclocker you are) instead of ~20% faster. Next year we should have 14-16nm HBM2 cards from both nvidia and AMD that should outclass 970/980 by a mile, in case you havn't bought anything else past single 970 by then | ||

http://www.banggood.com/EXP-GDC-Laptop-External-PCI-E-Graphics-Card-p-934367.html I got one of these. It's an external gpu thingy through expresscard slot. I hooked it up to my PSU as shown in the video. My problem is, it does not seem to fire up the PSU. http://img.banggood.com/thumb/large/2014/tanghong/07/SKU149984/SKU149984-62.jpg This cable connects the egpu dock with the 20 pin atx connector and 4 pin CPU power connector. But isn't something odd? How can it send the fire up signal through a single cable to 20 pin connector? Did they forget one line or may there be another issue?  | ||

It was fluctuating pretty consistently between ~$3.40 and ~$4.15 between quarterly report cycles before it tanked last fall a month before the quarterly and has stayed down in the mid to low $2's for all but a few weeks during that time. At least during the cycling it had positives coming out like the big console score. Right now it doesn't have much going for it in the way of future prospects, especially in the CPU arena. That said, I'm sitting on a bunch of AMD so anytime it wants to go up is fine by me... (btw newbie investors, once you have a stock for >1 year it becomes a long term investment and your tax rate drops from your income tax to capital gains which is generally lower - for most working stiffs here it'll go from 25-30% down to 20%). | ||

Right now it doesn't have much going for it in the way of future prospects, especially in the CPU arena. Zen, but they could target the midrange only (or worse, be unprofitable). Been coming up @2016 for aaaaages. Gotta compete with Skylake though, which, if having 15% higher IPC than Haswell, will be ~80-85%ish faster for singlethreaded performance on the same clock speed as Piledriver. they have like 0 RND budget for chips though, nvidia/intel are making a bunch and meanwhile AMD has a crazy amount of 2012 tech that's gonna be staying their best option on the market until 2016 - not because they didn't develop Steamroller, Excavator and GCN 1.1 - 1.2+ - but because they didn't have the money/profitability to actually put out chips with their new/better stuff (or worse; if steamroller/excavator performed WORSE on desktop than piledriver because of low power design considerations/process) | ||

Uni work which uses nothing Do you intend to overclock? no Do you intend to do SLI / Crossfire? not sure what that is Do you need an operating system? i have a win7 key Do you need a monitor or any other peripherals and is this part of your budget? no have mouse/keyboard/headset and 2 monitors If you have any requirements or brand preferences, please specify. thinking 970 and i5 4690? prefer nvidia/intel What country will you be buying your parts in? new zealand If you have any retailer preferences, please specify. not really, as long as it is reliable/good reviews. Pretty set on CPU/GPu unless someone thinks otherwise. need help for ram/mobo/PSU/case | ||

how light gaming? Maybe even broadwell i5 w/ iris pro is appropriate, if you were thinking of using a low end GPU | ||
