So i'll switch to the i5 4670. Get rid of the cooler. and swap my graphics card for the R9 280. Are you sure though that 450w will be sufficient? Several stores are warning me that the R9 280 requires at least 700w. I’ve read the part about manufactures over estimating power supply in the OP, but still from 700 to 450 seems like a big step down. | ||

Maxing all cores of an i5 with a game and live video encoding only uses ~60w at stock, too. The "tdp" (long duration package power limit for turbo speeds) is at 84w to account for some chips needing more voltage than others, using integrated graphics instead of a dedicated GPU to render games etc and i7 using ~15% more power than i5, yet having the same power number written on it - it's not a great indication of actual power usage at load. If there was a good selection of high quality PSU's below 450w, you would be buying one of those for that kind of system, unless you had plans to keep the PSU and use higher power consumption parts than a stock CPU and overclocked midrange GPU in the future | ||

so a week ago i asked in another thread wheather or not my cpu would be bottlenecking a new grafic card. The answer was that it was dependend on the desired resolution and games i wanted to play. Also i got the info that for sc2 my old grafic card should be sufficient and my processer seemed to be the limiting factor. my gear is this: processor: intel core i7 860 @ 2,8 Ghz mainboard: asus P7P55D LE grafic card: HIS Radeon HD 6950 ram: 4gb ram - i think its running on 1333mhz I then decided to buy a nice noctua cpu cooler and try to overclock the processor. Now i have no experience in overclocking so this is all pretty exciting to me. Before the new cpu cooler my cores were usually at 90°C, now they are at 30-40°C. In my BIOS i found no option to simply increase the clock speed. However i found some overclocking presets. I figured it wouldn't hurt to try one and booted, checked the temperature and as the system was stable for some minutes i repeated the process and switched to the next higher preset. For a few days my cpu ran successfully at the highest preset called "Crazy ~3,37Ghz" or something without any issues. This evening i discovered that it is possible to change the cpu ratio setting. Initially it was set to 21 and i changed it to 22. Here's what im at now: ![[image loading]](http://s14.directupload.net/images/141021/njt4bak8.jpg) ![[image loading]](http://s14.directupload.net/images/141021/kt5cqiv6.jpg) I read this guide http://www.overclock.net/t/1567/intel-overclocking-guide but frankly i don't understand it all. Imo its save to continue experimenting as long as cpu cores stay cool and the system remains stable. But what did those presets actually do and are the current overclocking settings at a decent spot now? Which direction would you go next, if i were to slowly go towards the maximum of my possibilities. Any help would be appreciated! Link to my mainboard manual: http://dlcdnet.asus.com/pub/ASUS/mb/LGA1156/P7P55D_LE/E4882_P7P55D_LE_manual.zip Pages 47-53 "explain" some Bios options for overclocking. | ||

The other setting you would probably change would be the base clock. 21x 133 = 2793mhz, but 20x200 = 4000mhz - i'm not certain for those particular CPU's though. My first gen i7 was a bloomfield/x58 system and they had some different stuff. Also i don't know how much your motherboard would limit such things | ||

http://anandtech.com/show/2832/18 http://www.overclockers.com/3-step-guide-overclock-core-i3-i5-i7/ Step 1) Maximize Bclock Frequency Isolate the bclock from the CPU First you need to isolate the bclock and find its stable limit with your chosen cooling. In order to isolate the bclock from the other components, the first thing you need to do is manually force a low multiplier for the CPU. For example; at stock speed, an i5 750 runs on a 133MHz bclock and a x20 multiplier which results in its stock speed of 2660MHz (133×20). Raising the bclock to 200 with the stock x20 multi would result in 4000MHz for the CPU, which you’re not quite ready for yet. If you are shooting for a 200MHz bclock, then a safe choice for now might be a x12 multi, which would result in a CPU speed of 2400MHz if you were successful in reaching your 200MHz target bclock. Doing this isolates the CPU from the bclock so you can focus on only bclock overclocking in this step. In some situations, x12 may not work, this is just an example though, so don’t be afraid to try other low multipliers if x12 doesn’t work. Isolate the bclock from the memory The fastest rated speed for memory on P55 with an i5 750 (for example) is DDR3-1333, which is a clock speed of 667MHz (dual data rate “DDR” doubles the bandwidth to 1333-like speed). Just like the CPU, the memory receives its clock from the bclock via a multiplier, in this case x5 (133×5=667). This is most often expressed in the BIOS as “2:10″. If you were to overclock the bclock to 200MHz as described before, your memory would be running at 1000MHz (DDR3-2000), and beyond the specs of all but the most extreme memory. To isolate the memory from the bclock, lower the memory multiplier to the lowest setting available, most likely 2:6. If you were to reach your goal of 200MHz bclcok frequency, your memory would only be at 600MHz (DDR3-1200) and well within the capability of all but the worst DDR3 on the market. | ||

Many of those CPU's couldn't do those kinds of clock speeds with 1.35v either. It only became common with later steppings - with bloomfield, d0 clocked as much as maybe even 400mhz higher than c0 on similar voltages, i heard | ||

Apparently my board supports cpu ratio settings from 9 to 22. Core Voltage Settings range from 0,85V to 1,7V (it's set to 1,25V) Also i found the BCLK setting which is adjustable from 80-500 (133 standard) I can't find where to manually set the memory multiplier. 12x200 -> 2400Mhz works while the auto DRAM setting adjusted its frequency to 600Mhz (which is 1200Mhz on dual channel?) FSP:DRAM ratio seems to be at 2:6 would you increase the multiplier now and slowly work your way up to 4ghz? also thank you for the link (http://www.overclockers.com/3-step-guide-overclock-core-i3-i5-i7/) seems very helpful - i will read it soon. update: im at 3,85Ghz now (20x192) 1,35V core voltage 578 Mhz DRAM core-temps during stress-tests at 70-80° 20x195 turned up errors during the test, also 21x192 resulted in a bluescreen. I will do some more testing for now. | ||

Then 20x200 and start testing for stability. If it passes something like IBT then 21x200 and if that 22x200. If it boots but fails IBT up vCore slightly (~+.0125v) and try again. Call it a day when it's stable and your happy with the results. EDIT: Set LLC to Enabled, Spread Spectrum to Disabled. EDIT2: And turn Xtreme Phase Full Power Mode to Enabled. | ||

There is one major short coming to it though: it can only do microATX. If they released an ATX version of this case it would be really nice. I like the dual exhaust on the back panel and the interesting mounting location for the PSU. This case has some interesting ideas. Also mounting two fans on front intake and two fans on back as exhaust seems really interesting to me, it gives a linear airflow. I wonder how good this case is / performs. It probably won't be cheap though, heh. I really, really like Phanteks cases. | ||

at 12x200 change RAM Frequency from auto to 1600Mhz and up the voltage from auto to 1.65v. It will only fail to boot if your RAM is bottom of the barrel. If it doesn't boot change back to auto. Then 20x200 and start testing for stability. If it passes something like IBT then 21x200 and if that 22x200. If it boots but fails IBT up vCore slightly (~+.0125v) and try again. Call it a day when it's stable and your happy with the results. EDIT: Set LLC to Enabled, Spread Spectrum to Disabled. EDIT2: And turn Xtreme Phase Full Power Mode to Enabled. I tried what you told me, but 20x200 with the 1600Mhz Ram (i set it to 1.6V since i could only increment it by 0.1) was not stable in the stress test. I slightly increased the vcore but to no use. I couldnt figure out wheather the dram voltage or the vcore or something else was the reason for the failing stress tests, so i decided to go with (22x174) -> 3828Mhz at 1,35vcore for the cpu and 700Mhz/1,5V on my ram. it was stable at ~ 10Minutes of stress test. Seeing as this is my first try on OC, i'm happy how it turned out. I will test it for a longer period of time soon. Thanks for the help guys. | ||

I'm trying to build a stand alone streaming pc (it will do only one thing, get video signal from main PC, encode it and send it to twitch in 720/1080p 60fps.) I'm trying to keep it cheap, where could i save up money in this build? So farm im looking at the following parts: RAM: HyperX Fury Series black, DDR3-1600, CL10 - 8 GB Kit PSU: be quiet! Pure Rock CPU-cooler - 120mm Case: BitFenix Prodigy Mini-ITX case HDD: Western Digital Black, SATA 6G, Intellipower, 2,5 inch - 500 GB MOBA: ASRock B85 Pro4, Intel B85 Mainboard - Sockel 1150 PSU: be quiet! Straight Power 10 PSU, 80Plus Gold - 500 Watt CPU: Intel Core i7-4770K 3,5 GHz (Haswell) Sockel 1150 - boxed GPU: My old radeon 7850 Capture Card: Live gamer HD lite I'm at around 800€ which seems much for a PC that will only stream doesn't it? | ||

If the system is high performance the PSU bakes to the point of overheating and more importantly if the system has a GPU with on open air cooler it will bake as well as there is no where for the trapped heat to escape. CPU thermal's are relatively good however. A minor redesign is needed. Something like a front lower exhaust slot (I believe there is space for a 120mm fan, otherwise 92mm) if your not using a cd burner and having a slim (15mm thick, 92mm) fan mount where the PSU exhausts. | ||

Up to you~ Mobo - maybe there's a cheaper one, looked at h81? PSU - no need for 500w or amazing quality, there's a lot of cheaper passable stuff probably CPU - i7 is ~20% faster than i5 for encoding clock for clock, but it's way more than 20% more expensive. i5 will do 720p60/1080p30 @ stock, neither will do 1080p60 at stock. You have 4770k selected which is weird, because if you were overclocking you would get a better 4790k (or i5 4690k) and if you wasn't overclocking you wouldn't get an unlocked CPU capture card: can't speak there, really | ||

i7 costs a lot more than i5 for that ~20% extra encoding performance at same clock speed. Also, 4770k is last-gen. You don't need to buy an unlocked CPU or a CPU cooler if you can't overclock anyway because of the mobo no need for 500 watt PSU, or super high quality for just a streaming rig. No need for good/expensive case for streaming rig 4gb of RAM would probably work fine Bah!:..so that moba i linked is not even good for overclocking 4770k? And I was about to ask if MSI AM1I (30€ lol) can work with i7 4790k and 8gb 1600mhz ram.... Could u please advice me a good board that can handle an overclocked i7 4790k maybe at 4.6Ghz and doesn't break the bank? Also how many watt should the PSU have would 400w silver be enough? | ||

Also how many watt should the PSU have would 400w silver be enough? b85 does not even have any OC support. For overclocking Haswell now, z97 is the only chipset that makes sense to buy new from a shop (because z87 requires a bios update to run 4690k/4790k, which are better than 4670k/4770k by non-negligible amounts) Most atx z97's will be fine, it's probably not worth to pay extra for quality if it doesn't make much difference and especially if it's not your main system. For cooler, something like a thermalright true spirit 140 power (or hr-02 macho, if that's unavailable) for ~35 euro is good, but take note that i7 runs ~7-13c hotter than i5 depending on the temperatures with similar cooling, so if you're buying cost effective cooling you would probably loose 100-200mhz of OC headroom and that 20% advantage would probably turn into ~15%, at a cost of like 100 euros. It's a pretty hard sell to get a 4790k over a 4690k, even for a dedicated encoding rig. If you care that much about 15-20% more performance than i5, then even an x99 system could be a better investment potentially, with the 5820k being not 15-20% faster, but ~70% faster, if a 4690k can't do what you want it to do a good 400-450w unit is fine | ||
