i5 3570k overclocking temps..?

[ckay27]

So first off I should explain my setup....

i5 3570k, 8gb cosair vengance 1866mhz ram, asrock z77 extreme6, akasa venom viper cpu air cooler, 650watts ocz 80+ modular power supply...
card is currently under RMA and waiting for a 7950 now xfx dd edition

I was overclocked yesterday at 4.0ghz at .005 voltage increase and played call of duty for 2 hours off the i5 graphics and hit these temps 60 52 55 55 as max after this session. I thought this was fine. I did not however use prime 95 to test.

I am currently trying to show someone why an i5 3570k represents better value than the amd 8core 8350, so I thought I'd show him the i5 running at higher speeds. Anyway back on point...

I am now oc'ed at 4.2ghz and gave a .015 increase to offset, under the presumption that this would be more stable. the vcore is sitting at a very stable 1.232 at full load. after a ten minute small ftts test i read max temps of 81 83 82 and 78. The temperature was not really gaining much at the end of the test. Only real concern is the ocz zt series 650w only giving 4.992 to my 5volt. Does this sound about right for you? Safe for gaming? And when the 7950 comes would I want to clock it back until I upgrade my psu? Before this I had it running at 3.6 with no tweaking for a month and no problems.

Feedback much appreciated

Thanks
chris

A couple of degrees lower on each temp after 20mins with .005 less voltage @ 4.2 and passed, this is perhaps better

From everything I have read, you should be able to hit 4.2 with your voltage set to auto. Your 650W PSU is plenty fine for a 7950 Overclock and a 3570K overclocked. Your temps do seem high for such a low overclock - the TJmax is 105C anything below that is fine. I am going to overclocking mine this week (Just got it yesterday) I am looking for the max overclock I can get while running prime in the 90C range max.

 

[runzwithsizorz]

Currently running my 3570k at 4.43GHz. spent 2 hours lapping, and prep on a
Hyper212 plus p/p, using Arctic Silver. Case is a HAF, with 9 fans. Highest core temp was 68c after Linpack benching. My vcore voltage,at 1.232 Still trying to familiarize myself with this Asus P8z77-Vpro bios. If I could lower the volts, and thus lower the temps I may go for a higher clock. Highest temps at full test load is 68c. Your voltage is fine. Your temps are high. What are you using for cooling? Also using slightly overclocked MSI HD Radeon Hawk 7870.

Just to confirm i am adding 0.010 to cpu voltage...are you saying I should put down and test again Face2Face?
I am using a akasa venom viper cpu air cooler http://www.google.co.uk/imgres?imgurl=http://img.systemaxdev.com/productmedia/htmlimages/cten/AKA/AKA-1/173698-front.jpg&imgrefurl=http://www.misco.co.uk/Product/173698/Akasa-Venom-Voodoo-Multi-Platform-High-Performance-CPU-Cooler&h=490&w=490&sz=50&tbnid=ApQ0Rep4sZFsOM:&tbnh=91&tbnw=91&prev=/search%3Fq%3Dakasa%2Bvenom%2Bviper%26tbm%3Disch%26tbo%3Du&zoom=1&q=akasa+venom+viper&usg=__udhdmA160GfjM91gQAsAd80p358=&docid=I8CqoWyOVeSxCM&hl=en&sa=X&ei=ChcQUZz3IOOd0AXe_oDgDw&ved=0CGkQ9QEwCQ&dur=66

I got the i5 back in october, maybe I need a new coat of paste?

Your CPU cooler looks good, and should be fine for a decent overclock. What is your base CPU voltage that your motherboard is reporting?

 

[ckay27]

I am presuming by base you mean vcore at idle? Otherwise what am I looking for sorry? Something in my actual bios? v core at idle is 1.005-1.011. I'm sure this isn't what you meant though....I am using the asrock extreme tuning utility...

 

[ckay27]

vccsa is 0.925 i think thats what you mean

 

[Face2Face]

I was talking about your VCore at load. Take a look at this blurb from an article at thinkcomputers.org. He is overclocking on a ASRock board.

http://www.thinkcomputers.org/intel-ivy-bridge-overclocking-guide/

First, set your VCC offset to +0.005v if you’re using offset, or set the VCC voltage to 0.005v higher than stock if you’re using fixed.

Now, increase your multiplier. Take it up 1 or 2 steps from stock. So up to 36 on a 3570k, or up to 37 on a 3770k. Reboot. Do you boot? Cool! Run Prime95’s Blend Test for 10 minutes. Do you get a BSOD, or a Fatal Error in Prime95?

Go back to your BIOS.

If you did get a BSOD or error, follow the steps according to the BSOD information below, and then try again.

If you booted and tested with no problems, increase your multiplier by 1.

Save your settings and attempt to boot again.

Remember you can use LLC Level settings to help with stability, too. You’re aiming to have the same voltage under load as the voltage you’ve set in the BIOS. If your VCore is dropped below what you’ve set when under load, increase your LLC compensation level.

Continue these two steps until you are at the clock speed you want, within the required voltage settings, and aren’t going over 90C.

Next is REAL stability testing. Run Prime95’s Blend Test for 8 Hours. If you remain error free, congratulations! If you’re going to be Folding@Home or other high-load applications, run Prime95 for a full 24 hours.. and just so you know, playing video games is not “high load.”

If you’d like to further test your overclock, run IntelBurnTest. WATCH YOUR TEMPS RUNNING THIS PROGRAM.

BSOD CODES

Some common important ones for reference:
0×124 = add/remove vcore or VTT voltage (usually Vcore, once it was QPI/VTT)
0×101 = add more vcore
0×50 = RAM timings/Frequency add DDR3 voltage or add VTT
0x1E = add more vcore
0x3B = add more vcore
0xD1 = add VTT voltage
0x9C = VTT most likely, but increasing vcore has helped in some instances
0X109 = add DDR3 voltage
0x0A = add VTT voltage
0x1A = Memory management error. It usually means a bad stick of Ram. Test with Memtest or whatever you prefer. Try raising your RAM voltage. Can also mean more juice for the south bridge ICH volts
0×19: memory voltage

 

[ckay27]

Do I really need to put an 8 hour stress on the cpu at full load? I only play games...if after an hour its passed and my temps are below 90 and all the voltages are fine this would be considered safe?
Going to write down those BSOD codes, much appreciate that and your time.

 

[runzwithsizorz]

When I left my voltage on auto I was hitting 1.33v, and high temp was 79c.
When I lowered, and locked the voltage at 1.232 my temp dropped to 68c.
I *may* try to drop the voltage even lower, for I think I have seen some people here on another thread do so and run 4.5GHz.
Your PSU will be just fine, it could probably handle a crossfire. Your HSF certainly *looks* up to the task, what is your ambient? We tend to keep our house rather cool, aprox. 62f . You may try re-seating your HSF, I pretty much had to use a whet stone on mine, and check the level with a razor blade.

I would encourage you to read the full article. I edited the post above with the link.
8HR stress test --- No, not just for gaming. I run it for 2-3 hours tops - I never game longer than that. Prime will put more load on your cpu than any game will. Let us know how everything turns out.

If anyone else can chime in and help it would be appreciated as well.

Thanks runzwithsizorz

Yeah F2F ditto!

 

[Vectronic]

No you don't really need to do an 8, 12, or 18 hour stress test.

But, you should probably play every game you have for 10 minutes a piece. Do a bunch of random sporadic web browsing... open 30 tabs, play 2 videos at once, etc.

Sorta do what you would do in a 2 days, in an hour.

Your temps are a *little* high, but nowhere near concern, you should be able to hit 4.2 easy, beyond that it really depends on how that cooler(?) behaves.

VCore: < 1.500 (you'll probably never get there, 1.3 will likely be your max before TJMax/105C and your CPU starts to throttle)

Don't need to touch these, but:
VTT: 1.000 to 1.100
PCH: 1.000 to 1.100
PLL: 1.600 to 1.900
VCCSA: 0.925

Many many threads about overclocking the 3570K, so look for those before starting a new thread.

 

[ckay27]

Ok I will be aware of that for future Vectronic.

I haven't retried prime yet, but I did play call of duty and as I have no card while its RMA I am using the I5s hd 4000 and max temp @4.2 was 65 62 65 61 with vcore i saw no higher than 2.56 though may have crept higher when I wasn't looking. No artifacts that I noticed on the graphics. Most of the time the temp was lower than 50 when i checked.

I have just opened a range of programs including UDK, office, and then loaded up a load of ie and chrome tabs and it seems more responsive than at stock speed. Somewhere around 40 34 40 34 on the cores with these open currently which is around 25% load according to realtemp. vcore 1.128 now. speedfan for some reason thinks the temp is 28degrees for the cpu, the asrock tuner utility is saying 40 however. I will be going onto rerun prime again next but these seem very reasonable temperatures and voltages and it did pass 16minutes of prime despite the temps. I can't see there being too much problem unless the 7950 might alter the complex slightly? I am not sure of ambient room temp, the motherboard is 27degrees according to two programs.

I think the next two logical steps for heat reduction would be to reseat the heatsink and lock the vcore voltage. Thanks for all of your input much appreciated all

 

[ckay27]

At idle it drops to 0.993 vcore and 32 degrees, but the clock is dropping back down to stock speeds down to 2.6 at 4% load...is this a bad thing?

 

[ShintaiDK]

Remember the tjmax for 3570K is 105C.

Clocking down in idle is fine.

Try use Linx/Linpack for testing too. its one of the most demanding tests. And use large amounts of memory.

 

[Vectronic]

Nope that's normally... when it's completely idle (actually anything under 1% usage), it should drop all the way down to 1.6GHz.

When it gets to about %20 usage, it will go all the way up to what the maximum clock is set to... anywhere in between it jumps around, trying to do two things:

1. Process what is requested as quick as possible.
2. Use as little electricity as possible.

 

[ckay27]

I have fixed my voltage now as this seems to have reduced temps between 15-20 degrees at 1.220 on the 4.2, however when running Prime 95 test, as soon as I hit 4k test after 15 minutes temps raise about 10 degrees, before the 4k i was at 67 66 68 64 and as soon as it went to 4k I am now reading 78 79 78 75. Is this normal and ok temps? This is 4-5 minutes into the 4k test.

 

[ckay27]

And back into the 512k test puts me back into the 60s again =) over half hour in now and the max was 79 81 81 77 if it stays stable then I think this is ok for me.

 

[Vectronic]

It's normal, if you really want to test for temperatures, use IBT/OCCT or LinX (<- gets me the highest temps).

For P95 Small FFT will get the highest temps, but they'll still be below LinPack tests.

 

[Macgruber]

hey with your setup do you _ever_ experience a cold booted when shut down for many hours?

I have the same ram and it seems my motherboard isn't friendly !

 

[ckay27]

What do you mean by cold booted?
