Following on from SimonMaltby's OCUK Sandy Bridge 5GHz Club - lets kick off with a Sandy Bridge 5Ghz+ Prime Stable Club.

I expect to see the 2700k's flooded at the top of the ranks with their claimed 5Ghz overclocking ability but we will see what's what as this test matures.


Rules

  1. Overclock must be 5.0Ghz or above.
  2. Overclock must be Prime95 stable for 8 Hours or more; Using BLEND torture test.1
  3. Core Temp 1.0 must be used.2
  4. CPU-Z 1.58 must be used to show core speed and core voltage.3
  5. Notepad must show username when taking screenshot.4
  6. Posted screenshot must taken during testing to show loaded speed/core/temps, image must be readable and include all visible information from 1,2,3,4.


Now I know this is going to cause some people to rant about what the best method is to stability test. This way is the OCUK way when selling overclocked bundles so lets stick with this to be in-line with OCUK.

Even after 8 hours of prime I've seen systems throw up an error on Prime, so lets use the word 'stable' loosely here - Is any computer really 100% stable without testing it for 365.242199 days a year.

Myself/Overclockers UK are not responsible for any damage caused to any components during this test. If you chose to test for stability at 5.0Ghz or above then you do at your own risk.

Please read ~~~~~IMPORTANT SANDYBRIDGE OC INFO: Voltages & OC Guide!!~~~~~ for Sandy Bridge guidelines.
 
Hall of fame.

1. Caksey - 2600k - 5009.5Mhz
2. ChrisGTL - 2500k - 5000.0Mhz

Nobody else yet?

Managed to get my vcore down even further, to 1.360v @ 5.0Ghz.

Shall repost screenshots when I get chance to Prime it again.
 
If you had made this thread 6 months ago you would probably had loads on the list. Think people are board now as its not a massive achievement for a sandybridge
 
5ghz 8 hours prime stable is not hard.

Just depends on how many volts you need to put through your chip.

You got lucky.

I didn't so i don't clock to that.

I've had it at 5.2 and ran prime for 2 hours but wasn't happy with the volts so i don't run it that high.

With the introduction of the 2700k recently I thought quite a few would be running 5.0Ghz 24/7, and as I want a second system I was interested to see how many 2700k owners are running high frequencies and are prime stable.

I wasn't lucky with my chip, I knew which batch I wanted and I got one.
 
True stability is prime 95 blend for 8hrs+ AND IBT maximum x50 on 4/8threads accordingly.

I'd managed 2700k@5ghz prime stable on 1.41v for a 10 hour run, but it wasn't IBT (standard let alone maximum!) stable so scrapped the screenie lol :P
 
50 IBT runs is overkill, there is no real point in punishing your cpu for so long.

Yes I know you will say the point is to proove stability, but save that for the long prime 95 run at cooler temps.
