My first new OC in years...i2500K / AsRock Extreme3 Gen 3 / HC100

I had to mess with some settings and learn all over....ONce I realize my ram was set too high and I need to take it out of the equation by setting it to 1333 right now my OC has gone from 4.2-4.7ghz....I also used the vcore the PC set 4.4ghz.

It may be more then I need since i have gone 300mhz past it and still climbing, but when my load temps are only in the mid 50'sC I aint to worried yet....

Current:

47x multi for 4.7ghz...1.325v set...boots around 1.36v and loads at 1.33-1.34v
Temps.

idle was like 29-31C
load (OCCT & prime95) 54-56c
HC100 set to high but the system is more silent then my TRUE120 was with a Antec Tricool on high


OCCT (Large Data sets)/Prime95 running (I think I set large FFT) = 6hr 20 min now...


HOW DO I POST A PIC HERE?

Also noticed huge load swings from vcore until I set to load calibration 1. It seems to hold the line on the juice without having the excessive vdroop. I only see about .03v now when it was like 0.08v plus with load calibration 5 or auto.

Has anyone else noticed this?

Other notable settings:

PLL overvoltage = enabled
INtel Speedstep = disabled
INtel Turbo Boost = disabled
core current limit = 200
spread spectrum = disabled

Actually have vcore set to 1.325v and it overvolts initailly at bootup.
Load Line Calibration = 1
DRAM = 1.5v

All advanced CPU settings turned off except "thermal throttling"
 
Alright my testing is at 8+ hours no errors....so I think I am going to stop it....get some work done and then tonight try 4.8ghz...
 
If you are testing CPU for stability then don't use large FFT with prime95, use small FFT.

However, really you should use LinX and set the memory usage to "All". This will tell you real quick whether you are stable or just borderline.

Also, to post a pic, click the button that looks like this

and paste in your link to the pic.

For reference, here's the GHz versus Vcc I needed for my 2600K.

I did run the small FFT for 2 hours at 4.6ghz. I ran the large FFT for heavy power draw and max heat....

I downloaded linX and it seems funky or I dont have it set up right. I start running it let it run for like 30 minutes and I noticed it didnt increase the temps one bit. Does that sound right?

I will post some picks.


I am hoping I have some room left at 1.35v and i haven't really found its wall yet to go up a bit. 5ghz would be a nice milestone.
 
OK,

thanks for the tip IDC....I had to change my user settings to see these options

I got a few random BSOD's at 4.7ghz....

That was despite the fact I ran 9 hours of OCCT, 9 hours of prime Large FFT., and overnight Prime95 blend....

reading up I think it may have been related to an issue with a bios setting and sleep mode my for the monitor. I set bios settings back to default

I am working my way back up but I kind of got lost in all of the settings I was modifying...I went real simple this time.

I booted up at 1.3v 4.4ghz and ran overnight Linpack....no BSOD in the last 24 hours of similar activity as at 4.7ghz...


I tried to boot at 5ghz no go....even with 1.4v set it wouldn't post. I am working my way back up to try again but will take it a bit slower to make sure I have no instability....

Are you refering to internal PLL overvoltage and windows sleep/hibernation mode? They don't like playing together apparently. If you need PLL overvoltage for the higher clocks just disable slee mode in windows.

Duvie! Long time no see!

That's (above) been my experience, though my voltages are a tad higher. Anything above 4.7 and my thermals are far too high. 4.6 has been my sweet spot. Hate the UEFI interface, though. Hate it. Dumbs things down and makes it hard to find settings. I don't see any significant performance benefit either. The SSD has a much bigger impact.

Yep that is the one.....

I am trying a few different things this time....

I am about 3-4 hours into testing and stressing with no issues at 4.5ghz and still 1.3v. So far so good "knock on wood"

I will try that if I hit the wall and need the PLL overvoltage back on.


To be honest I got lost in how many things I modified. I should have known better to track it and only change one thing at a time...Godd a little to overzealous...been out of the game a bit....

I will be around a bit more.....

I have the HC100 and my thermals were quite low still even at the 4.7ghz. I ran several benches at 4.8ghz but with a random BSOD I have to find the culprit an drule stuff out. I cannot have random BSOD....

I may have resigned to the fact that 5ghz is either unattainable or just more then I am willing to go for the added vcore.

From where I am coming this is a heck of an upgrade.

I think I am going to invest in an SSD drive next...
 
Here is my overnight stress testing at 4.5ghz....

The prime95 was small FFT and all 4 cores for around 4 hours...then I sent LinPack and gave it full memory range and went to bed....

Now off to work...testing for 4.6ghz to come tonight...

Temps and volts look good.

But I'm sorry to say it doesn't look like a golden chip in the sense that mine wasn't a golden chip, you seem to be roughly tracking the Vcc and GHz that mine required.

In my case, to see what it took to be 5GHz stable you can check out this thread. I had to lap both my 2600K and H100, use 1.5Vcc, and my LinX temps came it around 93-94C. 🙁

I hope I'm wrong and yours gets there with less Vcc and lower temps.

Oh, I definitely agree with you....This is not going to hit 5ghz without more vcore then I would be willing to giveit for the long run....I will go up as high as 1.33-1.35v will take me and live with that.....

It will be nice to post 5ghz and take some benches and whatnot, but I doubt it will ever be set there for day to day operations...

Recommended. But get as big a one as you can afford. (I don't think 128GB is enough now. Plus prices are dropping.) And install as much RAM as you can use and run the swap file on it. DDR3-1600 is plenty good enough.

I wouldn't worry. Real life difference beetween 4,7 and 5,0 Ghz SB i5 is probably impossible to notice anyway.
 
Here is some testing at 4.6ghz....After a few hours of prime95 small FFT I needed to boost the vcore a notch with 4.6ghz....Afterwards I ran some Folding at Home and here is my run at approx 12 hours.

This is for Mark_F_Williams...PPD is near 17k now. I dont think I woudl hit 20k unless I had the i7 variant with the hyperthreading like your oc'd 920's and 930's....

I may in a few weeks pop out this 2500k and try a 2600k if the price comes down for some testing...
