It looks like either the motherboard is messed up, or the processor isn't actually a fully unlocked i2500k. I've even tried running the AI Suite and it overclocked the bus speed and wouldn't even touch the multiplier at all. Regardless, the place I got it from will accept an exchange on both the motherboard and processor, with zero restocking fee, so no worries. Thanks everyone who helped with suggestions, looks like I'll be rebuilding tomorrow.

Normally I would be very confused as to why you are having problems, but it seems like since my last restart, I'm suddenly getting the same thing and the multiplier adjustment in AI Suite has disappeared.  E: Rebooting fixed me up... hunh. Well, here's looking forward to the next BIOS update. Factory Factory fucked around with this message at 04:04 on Jan 22, 2011 |

Good luck, hopefully it's just a glitch! I feel like I'm the only person who has actually had a problem with Sandy Bridge, everywhere else I look everyone's gushing about the easy overclock. I'll probably pay the difference and upgrade to a 2600k anyway, so no biggie.

Is it normal for my 2500k to idle at 45C in the BIOS? Is the temperature reading inaccurate? I have my thermostat set to 32C (although I don't know the actual room temperature). It's just that I got a Noctua NH-U12P and according to some web sites, the 2500k runs at much lower temperatures even with the stock cooler. Is it just my hot room, or should I re-seat the heat sink? It would be really helpful if anyone could tell me what temperature their P8P67 bios reports for the CPU.

Yes, it's normal. As covered in the last few pages, a modern operating system will halt the processor, then tell it to wake up when it has work. When halted, that's the idle state. A BIOS, even UEFI, is not that sophisticated, so the processor is constantly polling the mouse to be able to respond to clicks and update where the pointer is. Your processor is actually busy most of the time in UEFI, just not with really taxing work, so you will see a "light load"-type temperature.

I've been running my 2500k at 4.0ghz from the first power on with my new system with absolutely no problems at all. I decided to run download Real Temp and Prime 95 last night to see what my temps are. Got as high as 74°C before I shut down Prime95 (less than 10 minutes of running). Dropped the multiplier back to 33x and have been running Prime95 in the background, temps are about 66°C. I'm pretty sure I installed the stock cooler correctly (it doesn't move at all, clips are all correct), although I didn't take the time to dig out my Arctic Silver and just used the thermal paste that Intel ships on their stock cooler. Anandtech had a system running at 4.4ghz on the stock cooler - although I don't recall seeing their temperatures anywhere. I'm seriously considering a Cooler Master Hyper212 cooler just to get my temps down. I smoked an Athlon many years ago trying to overclock it on inadequate cooling and don't want to do the same thing with my new CPU. Am I over thinking this? Should I even worry about temps that high?

I'm assuming you have it set to auto since you haven't said otherwise. Following the guide posted earlier, I started at 1.12v and after a couple of spectacular failures at loading Win 7, went to 1.2 at the stock multiplier. Temps aren't really any lower while running Prime95. One thing that is interesting is that while Real Temp is giving me temps of around 30° at idle, SpeedFan and the Gigabyte software are showing them around 16-17°C. I'm not sure why the values are different when they're supposed to be reading the same sensors.

I think EasyTune reads the Core 0 temperature only. My theory? Core 0 is next to the unused (for us) graphics core, so it has a lot of excess silicon to spread the heat around, whereas Core 1 and 2 are surrounded by other heat-generating components.

Finally assembled and running! Windows didn't complain at all, stable (so far) at 4.8GHz, load temps w/ OCCT at 65C. (i7-2600K, P8P67, 16GB RAM). No errors in RAM either! Pretty pumped, can't wait to throw some games and VMs at this sucka. I didn't clean off the heatsink as well as I could have (no rubbing alcohol, and was lazy so I used vodka instead), but the temps are pretty much the same I was getting with a C2D, so I'm OK with not messing with it any more.

Anandtech posted:However, the second question is: ‘what about the comparison to the ASRock P67 Extreme4’? The ASRock board has power/reset buttons on the board, a Debug LED, that USB 3.0 bracket which will hold an SSD (worth in my option about $15), and is almost $40 cheaper. The ASUS board is the slightly better performing, overclocking is easier on the ASUS, the ASUS has a longer warranty, the UEFI is slightly better on the ASUS, the ASUS uses Intel Ethernet rather than Realtek, but the ASRock will take socket 775 coolers. It is up to you to judge, but in my opinion, I would take the Extreme4, pocket the $40 difference, and invest it in something else for a PC build. e: oh, the regular P8P67? Don't think so.

I'm totally satisfied with my UD4. No UEFI, but who cares about that. AFAIK it'll still boot off a 3TB drive, if I had one to throw in there. I don't care about boot speeds, sleep has totally replaced shutdown for me.

Haha I couldn't figure it out either. Is there really much real world difference in terms of games when overclocking higher and higher on the 2500k? I did bump my cores up to 42 for a 4.2 GHz overclock on the Hyper 212. I had no luck at all overclocking my old E8400 so I'm being really conservative with this 2500k. 3.3 > 4.2 was a realistic OC and actually seems like it made a couple FPS difference in Crysis on Enthusiast, but that could be just me wishful thinking. I'm considering bumping it up to 4.5 GHz but I've no idea what to put the voltage at. I've been told 1.300-1.350 are about the max you want to do, but that's on some other message boards where people get a hardon for 5.0 GHz whereas I couldn't care less about having a signature with my e-penis processor. I'm pretty sure I mounted the Hyper 212 right, but there's not much to go on. My idle temps are around 29 degrees on all 4 cores and hit about 54 degrees on Intel Burn Core after 10 regular tests. I didn't use Arctic Silver [just the stuff the 212 came with] and it's only got the push fan. I'm also considering adding a second fan on but not sure whether it's worth it or not, I'm pretty sure there's enough room in the case for the push/pull as people say.

I POST'd once at 5.0GHz but that was at scary scary high VCore. Settled @ 1.3V and 4.8GHz, a happy medium. It would survive OCCT Linpack at 1.2875, but Black Ops and Force Unleashed would BSOD in minutes  Putting my BCLK above 101 causes instability galore, so I've just left it at 100.0.

I like the easy overclocks that don't require a ton of trial and error stability and settings changes. As soon as I got my setup up and running I set all 4 turbo multipliers to 40 and after two 12 hourish prime95 runs without errors I set it to 4.2 and did a couple more overnight torture tests. You have to remember that an i5 2500 has a normal turbo speed of 3.7, so in my case its only a 500mhz overlock. I also left all voltages at auto, the only settings besides the turbo multiplier i changed was phase control or something, which I set to medium. I might try 4.5 one day when I'm bored but I doubt it would be a big difference from 4.2. Going by various forum posts it seems 4.5 and up is where you start having to really tweak things and raise voltages to stay stable.

I just got my system together and bumped all turbo multipliers up to 41, didn't touch any voltages or thermal throttling etc, and it keeps on downclocking back to 3.8 or 3.7 when running prime. Temps are fine, do I maybe have to manually reduce the vcore or increase some of the short term turbo settings? (i5 2500K on a Intel DP67BA)

What motherboard and bios? That sounds weird, are you sure you didn't set the turbo multiplier to 41 for only certain cores? You can set what you want to be on all cores or a per core basis. Also I figured I'd post this here as its kind of neat. Click here for the full 1841x563 image. I used Realtemp to log my cpu speed and temps one night during a WoW raid, the graph begins about 1.5 hours before the raid and ends about 1.5 hours after. It has some nice features like excel output and I like it a lot more in general than hwmonitor and coretemp.

Motherboard is Intel DP67BA, bios is the latest the autoupdater found. I have base multiplier and all 4 turbo multipliers @ 41, yet CPU-Z still shows it only going up to 3.9ghz, and it quickly drops down to 3.3. It seems like some of the options are just being flatout ignored. I'll try RealTemp, but I doubt its the readings

I don't know what to say except that Intel motherboards have never been very good for any kind of tweaking or overclocking. I assume this is the bios you're using, its the newest one I could find on Intel's site. I don't think its worth it to by a new motherboard, but in the future if you plan on overclocking or tweaking at all I'd get a non-Intel board (Asus, MSI, or Gigabyte).

Yup, thats the version I'm using. Overclocking wasn't my main goal with this build, but I just noticed that whenever I change values in the options page of the bios, the overview page has the values in the "default" column changed and not in "active"... so I'll just wait for a new bios version.

Drewjitsu posted:With a p183 and stock fans, how much can I comfortably push the 2600k? Every chip is different; I think I'm lucky to be stable at 4.8GHz at only 1.30Vcore. The ideal goal is to crank up the multiplier while not changing VCore. Realistically, as you crank up the multiplier for maximum turbo frequency, you will have to increase VCore if you want any resemblance of stability. With that said, you also have to keep it within safe thermal margins. You should be able to hit 4.4GHz with some very minor bumps in VCore. It's pretty late for me, and I don't recall the safe voltage limit at the moment, but I honestly wouldn't go above 1.35V for 24/7 operation. My personal goal was to stop at whatever frequency resulted in stability at 1.30V. I have no idea how hot your ambient environment is, or what your case airflow is like, but IMHO, idle temps should stay below 45C or so. My ambient is around 26C I think, and I idle at 37C, load at 65C. One GTX460 and 4 HDDs inside case, 4 undervolted fans. e: My heatsink is the Ultra 120 Extreme with a SFF21F strapped to it.

For some reason I'm hitting a hard barrier at 4.5GHz with my 2500k. It's rather interesting, I can run rock solid at 4.4GHz with 1.30v but 4.5GHz+ with any amount of vcore causes it to hang when trying to boot into Windows. It's just strange because it's not for a lack of voltage or too much heat... I'm almost tempted to try a Linux live cd to see if that will boot.

So what happens with this built in graphics stuff on the 2500k if I have a mother board with no integrated graphics card? (well, at least I can't see any monitor output on it...) Will it work through the GPU card I'm getting, or does it just not matter anymore because it'll be eclipsed by the 460 card?
