OCUK Sandy Bridge, SB-E and Ivy Bridge 5GHZ Club

I cannot seem to push past 4.5ghz without a blue screen in prime testing.

All voltages on auto at the minute and its more stable

CPU PLL AUTO (1.80)
Memory is corsair 2000mhz stuff @ 1866, i dont even know if i can set it to 2000 seems like 2133 is only option. thats at deafault which is 1.65v

any ideas on how i can push past 4.5ghz maybe to 4.7 on the UD4?

I'd drop the memory down first to 1333, manually set the timings and voltage and see if that helps.

Ive got a 2600k under water now and will start clocking soon. 5Ghz is my first real target. What sort of voltage do you think i will need (if i have a good chip) to get there?

It all depends on your motherboard. Each board vendor has different voltages that are needed.

But rule of thumb the following voltages are needed just to boot into OS at 5GHz.

vCore 1.440
Vtt 1.07
PLL 1.76

They are not writ in stone and are guide voltages only. Some CPU's will need more and others less.

So contagious it is.

When i run prime i almost 90% of the time end up getting this error. Be it after a second or after 20mins.

A clock interrupt was not received on a secondary processor within

Slight improvement on my score.

Not really sure if I needed that much vcore. Just whacked it up in a very unscientific way

All, for those of you that can run at +5Ghz, why not come over to the Custom PC thread and run a real benchmark

That's a burn in utility

I have made it

(about time).

Not really a good score but hay hoe im in now

Congrats.

Thank you clare

.

In case any is thinking why my Vcore is showing 1.04v @ 5.1ghz don't worry it's wrong for some reason it should be 1.5v

For some reason I am having problems with Super PI in that I cant get it to work at any clock speed. Do

I get membership anyway with this?

Ferax · 26 May 2011 at 22:56

Am willing to do more if required

Edit: I mean in terms of proof...

The results are based on Super-Pi order, so you have to get a super-pi run done. sorry

Ferax · 26 May 2011 at 23:55

ok, does this do it

That will do... but there is something seriously not working right there, your score is way slower than it should be.

EniGmA1981 · 27 May 2011 at 00:16

plus that's 4.98... not 5.0

Ferax · 27 May 2011 at 00:19

Any idea what that might be? I am a newcomer to all this, so would appreciate any advice.

I have taken the clock speed up to 5GHz, but not at a day to day voltage. Also, the RAM timings are a nanosecond out. Is this enough to explain the discrepancy?

If not, I would love to know where I'm going wrong!

oh my god, a pedant!

Will go for 5.1 if you need it
