What are the chances of getting a better 2500K than this?

I'm guessing this is fairly average? the Vid is around 1.411v at 4.6GHz and 4.9GHz, should I be greedy and buy another 2500K?
2500K: Batch No: 3138A838
4.9GHz = 1.408 load (prime95), 1.408v load (IBT 2.56) 1.424v idle. (Manual CPU Voltage = 1.43v BIOS)
4.9GHz = 1.400v load (prime95), 1.42v load (IBT 2.56), 1.01v to 1.06v idle. (Auto CPU Voltage)
4.8GHz = 1.336v load (prime95), 1.344v load (IBT 2.56) 1.352v idle. (Manual CPU Voltage = 1.36v BIOS)
4.7GHz = 1.296v load (prime95), 1.296v load (IBT 2.56) 1.312v idle. (Manual CPU Voltage = 1.32v BIOS)
4.6GHz = 1.384v load (prime95), 1.408v load (IBT 2.56) 1.01v to 1.06v idle. (Auto CPU Voltage)
4.6GHz = 1.280v load (prime95), 1.280v load (IBT 2.56) 1.296v idle. (Manual CPU Voltage = 1.30v BIOS)

I just got L131B325...how that you guys get so different batch number?

mine is made in malay.
Was yours from OcUK too? I got mine yesterday. This one is made in Costa Rica.
 
Have you tried lowering the vcore using a negative offset?

My auto vcore is always a lot higher than what I actually need to make it stable.

You tease! my inferior MSI board doesn't have such features lol. :( lol

What you got yours clocked at and settings for offset? I'm tempted to get an Asus / Gigabyte motherboard so I can have a go.

I'm guessing for for my 4.8GHz offset I would need around 0.06v negative offset, do you reckon it would let me do that, im more worried about my idle voltage.

I went through an expensive experience when I got my SB rig. I've owned all the P67 top boards from Gigabyte, MSI and now Asus.

Asus has been the best board for me by far - the Gigabyte didn't give me stable overclocks (but that was around January and I think the BIOS upgrades have been good since then)

Next was the MSI GD65, for me was ok at overclocking but slow a POST and I didn't like the UEFI BIOS layout.

Went to the ASUS last and love it best by far, its quick, my mouse works perfectly on the UEFI and it overclocks like a beast.

I'm going to do some proper overnight testing soon, I didnt have the time to test 5.0Ghz stable back then but I know one thing for sure......both the Gigabyte and MSI boards wouldnt even boot at 4.9Ghz nevermind run SuperPI at 5.0Ghz like on the Asus.

I like the sound of the Asrock hardware too.


Just for laughs!!

I might get the Asus P8Z68-V GEN3, looks a good board, I usually go for Gigabyte - this was my first MSI motherboard.

Mine is a:

L104A368

HTH
See this is the thing, my week 4 was ok for 4.6GHz using Auto CPU Core Voltage at 1.328v, anything above that it woudn't even boot regardless of voltage, still good for everyday use don't get me wrong.

2500K: Batch No: L104A429
4.6GHz = 1.336v load (prime95), 1.36v load (IBT 2.56), 1.00v to 1.05v idle. (Auto or Manual CPU Voltage) (Maximum Clock stable)
4.5GHz = 1.328v load (prime95, 1.352v load (IBT 2.56), 1.00v to 1.04v idle. (Auto or Manual CPU Voltage)

I have an Asus Z68 pro board and can clock my 2500K to 4.6 GHz with an offset of -0.035V and a vcore under prime 95 of 1.235v
What was your VID at 4.6GHz? mine is 1.4011v

@ Nelly, do you change other settings @4.9GHz on auto voltage?

I have the GD55 and got 4.7GHz playing about with settings, but I didn't know it could possibly hit 4.9GHz on auto v.

Above 4.5GHz I have:

Internal PLL Overvoltage = [Enabled]
CPU PLL Voltage = [1.800000 V]
 
Thanks, I have just came from a Q6600 and don't really know the ins and outs of SB oc'ing, any other settings or is everything else left alone?

That makes two of us, been with AMD for over 2 years, learning myself.

I think it's really more down to the CPU, I would use Manual CPU Voltage and go up with increments of 0.01v and keep testing with IBT, keep an eye on your temps as well I've got a good Air Cooler.

My CPU is okay but need a different motherboard to lower my voltages using offset, like I mentioned earlier using Core Temp my VID even at 4.6GHz on Auto Voltage is around 1.4011v, check your VID see what it is at whatever clock you have.
 
Have you tried pushing it higher? whats the batch of that CPU?

Mine was bought from OcUK and the batch number on the box is L127B277 and was made in Malaysia, I can't try to push it higher due to the temps my case only has 1 rear 120mm fan and no other ventilation holes :mad:
