So I'm thinking of overclocking my i5 2500k. This will be the first time I've attempted overclocking, so I'm going to try and understand what's being said in the OP. But first, what is the max tempurature I should be getting on my i5 using a stock fan running at max load? I always seem to get around 80 degrees C. But the OP mentions that 72 is the recommended safe tempurature when overclocking, so I might be quite a ways away from even attempting this.

Just buy a cheap cooler like the 212 EVO, it's not worth the trouble of working with the stock one unless you're completely broke.

I did exactly the same thing with the same processor and stock cooler a while ago and I was also getting around 80 degrees while on high loads. I got myself a Cooler Master Hyper 212 EVO and now I've overclocked it to 4.400 MHz and I'm running 60 degrees while on 100% load. tl;dr: get an aftermarket cooler, the stock for the 2500k sucks arse. /edit: ^^^^ what he said. If you want go to my post history on this thread and you'll see a few posts with people recommending coolers and talking about overclocking the 2500k.

Well drat I think I'll do just that. Thanks! Now I'm just annoyed that I've worn my CPU down at this tempurature for like 3 years.

Zero VGS posted:Does it stutter for you when it hits 100%? Not really? I did have minor occasional stutter that could've been attributed to the CPU but I just played the game a lot and didn't worry too much about performance. Definitely a CPU bottleneck often though, could do with a higher CPU clock than my stock clocks undervolted 3570K.

Seems like 4.6 Ghz is my max, how come I can't go higher ? At 4.8Ghz the computer reboots if I put any load on the fpu http://valid.canardpc.com/raeeu6 Temp is 83c after 30 minutes of stress test, I feel I should be able to go 5 Ghz but it just reboots for no reason, I'm confused

Try to keep it at 1.35V or less. My Sandy Bridge i7-2600k runs at 4.3Ghz on stock voltage (1.25V), but 4.4Ghz immediately requires 1.36+. Most of the time that extra 200MHz isn't worth it. Try running the chip at 4.4-4.5Ghz and 1.35V.

I finally got my hands on a new cooler (coolermaster hyper 212x) and the Z77 board I ordered. Now I'm wondering, what temps and voltages should I be aiming for with an i5 3570k? I want a comfortable overclock rather than a total bleeding edge one, I'll be happy with anything over 4ghz though I'm aiming for 4.4.

Does the clock speed of RAM even matter? I've always heard it was timings or whatever. You'll notice a small difference with the speed adjustments. Timing adjustments are tied with speed for the most part, each timing number is a clock number of how frequently can the system send that kind of order to the RAM. The idea is to get those as tight as possible to the actual time it takes to complete a job on the stick of RAM, so that way we can send another order sooner than later. Turning on XMP will get the timings close, but not bleeding edge wasting few cycles, and for somebody new to overclocking, I would recommend just turning on XMP and leaving it as is. It's somewhat common to see sticks that are listed as 1600 automatically clock to 1333, this is a safe operating speed that requires no real concern for operating conditions as the speed is slower than what it can accomplish and the timings are extremely loose where we're wasting cycles, again, enabling XMP will correct. To analogize, the timing on the RAM is like the timing on your car's cylinders, spark plugs, and fuel injection, tinkering with it can yield some positive results, massive tinkering will break things. Once you're tuned in to multipliers, bus, and Vcore as the basics and have them down pat, then move on to the memory, in the meantime, set the speed up, and leave the timings alone, ESPECIALLY if you have mixed brand/model. cat doter posted:I finally got my hands on a new cooler (coolermaster hyper 212x) and the Z77 board I ordered.

I want a comfortable overclock rather than a total bleeding edge one, I'll be happy with anything over 4ghz though I'm aiming for 4.4. I'm sitting on a Haswell i5-4670k with a Z87 board and Corsair H80 watercooling. I can push this chip from 3.4 to 4.4 with a small bump to the Vcore (I think I had to push .6v extra) and only multipliers, and it's pretty stable, though it heats up REAL fast when I hit it with Prime95 x64. The 3570k is roughly the same, just Ivy Bridge which if I remember was one of the hotter models. Looks like operating voltage is about the same, I wouldn't push more than .5v extra, and you'll want to keep the chip temperature under 65c during load. Push up to your target speed step by step, there are reports of the 3570k operating at 4.2Ghz @ 1v but you'd likely need better cooling. I suspect you'll be fine somewhere around 4Ghz @ .75-.85v, the only concern would be the cooler keeping up and room/case temps. Cynagen fucked around with this message at 08:35 on May 19, 2015 |

So I think the motherboard I bought may be faulty, I press the power button and the fans spin up briefly, then stop, then they spin up briefly again, etc just looping over and over. No overclocking for me. Though I did have the power cable half plugged into the power supply by accident when I plugged it into the power point, that's not an issue right?

If you didn't plug it in all the way, you may have left crucial supplies disconnected. Reseat everything firmly and try again, provided that fails, then replace the board. 1155 is getting a little harder to find good replacements for.

I've seen that exact issue turn out to be a PSU before, and seen that issue to be a motherboard before. If you've got a spare PSU lying around or one you can borrow to test, thats probably a good start. Unless you didn't get a new PSU at the same time and youre still using the same PSU on that new board, its probably the board

My PSU seemed to be on its last legs and whatever I did killed it. Bye bye 850w 80 plus silver rated PSU. Ive got a zalman 600w in there now. Bye bye Z77 chip set, gonna have to put in the old board for now.

Just overclocked my Asus ROG G73SW by following the information provided here. Was Intel I7-2630QM @ 2.00GHZ {8}cpu Now Intel I7-2630QM @ 2.12GHZ {8}cpu Only noticing about a 6 Celsius temperature increase, so I may attempt to up it a little further.

Rexxed posted:Just be really careful with overclocking laptops, they're not generally built to remove more heat than they can produce at stock speeds. Desktop-replacement and gaming laptops probably do a bit better than average, but yeah, you're not going to push a laptop too far. NVIDIA actually disabled overclocking on mobile chips in their newer driver releases citing heat dissipation problems. Another problem I've run into is that once you overheat a laptop, you can "cook" the thermal paste. The paste will stop transmitting heat to the cooling system and you'll end up with more and more overheating until you open it up and re-do it. HP laptops, in particular, have the shittiest paste I've ever seen. It's just a time bomb waiting to go off. The good news is that problem is totally fixable, unless you actually burned up a component. Grab a tube of Noctua NT-H1 off Amazon and go to town, it'll be way better. Also consider buying a replacement cooling assembly and a keyboard off ebay since you'll be taking it all apart anyway. Paul MaudDib fucked around with this message at 00:41 on May 22, 2015 |

Bear with me here because I'm a big dumb-dumb when it comes to overclocking. I decided yesterday to OC my 4 year old 2500k to get some extra juice and get some overclocking experience for my future builds. I've only really touched the multiplier and vcore voltage (my Gigabyte P67A-UD3-B3 motherboard only has that old-timey BIOS and they've always freaked me out) but so far I got it from 3.3 GHz to 4.2 GHz at 1.280V and it seems to be stable so far. Running Prime95's torture tests for a couple of hours puts max temps at around 74-75 degrees C with my Hyper 212. Granted, I haven't done much fine tuning and my case is probably a dust bunny collectathon but does this sound okay overall for a quick n' dirty OC hackjob?

Most 2500Ks hit diminishing returns somwehere around 4.2-4.5 ghz range.

I finally got around to overclocking my 4690K in the hopes it would make Witcher 3 run better (it didn't, really, sadly), but I had a few questions. Currently it's set at 4.7ghz and 1.225 volts. It's an Asrock motherboard and I've got it set to adaptive, so HWiNFO is reporting 1.237 volts as the max it's hit, which still isn't terrible. My real question is if I should back it off a step, because while it makes it through short tests in OCCT at temps in the low to mid 70's, when I went to run prime95, it gradually climbed up to 99 before I chickened out and stopped it. I'm assuming that's too high even for prime95, but it only took 5 or 10 minutes to get to that point and people always talk about running prime95 for 12 hours to make sure everything is stable. In comparison, I played Witcher 3 for 2 hours or so and it barely broke 60. So am I safe or should I dial it back a little?

Are you using adaptive voltage? Dont do prime95 or occt with adaptive voltage

So if I do fixed voltage prime95/OCCT won't melt my processor and I can change it to adaptive once I'm done stress testing?

The problem with adaptive on prime95 is it will raise voltage above whats needed. so find your stable voltage at your stable speed. Then use adaptive to in real world.

I read that that could be a problem, so I kept a watch on it and it never raised nearly as far from where it was set as people complained, but I'll take your word for it rather than fry my chip  .Two more questions. First, there's a setting called Vcore Voltage Additional Offset, which I've just left on Auto because I couldn't find a consistent answer as to what it does. Do I need to worry about it at all or just continue leaving it on Auto? Second, I saw someone mention that the CPU Cache Ratio shouldn't be too far from the Core Ratio. I set it at 35, which should be the default, because I also read that overclocking the cache doesn't get you very much and I wanted to keep this simple. I'm not endangering anything or leaving big gains behind leaving it alone, am I?
