kickin myself a tad bit

post #1 of 15
Thread Starter 
I had a 2600k which a tech thought was defective, was batch 208 (it was my mobo which was the problem). Anyways I would've had to pay a 15% restocking fee if I didn't try the processor first, as that's what he insisted was the issue. So I returned one, then the other same day lol, and got new of both CPU and mobo (this was a few days back).

Got a batch 243 as a replacement, and I just realized now that my batch 208 chip I had before seems to be getting better OC's with a lot of people. :O Kicking myself a bit.

I get 4.7GHz @ 1.42v stable, and 4.4GHz @ 1.315v stable... so not bad... just not impressive. I'm seeing 208 batches getting 4.5GHz @ 1.29 and things like that... :O

I'll check my batch. I'm at 4.5Ghz @ 1.275v with PLL @ 1.70 and QPI/VTT @ 1.080

LOL. well, hate to do it, but...5ghz @ 1.4v load is what seems to be average of the 208 batches.

I can't quite seem to figure out how the VTT effects the overclock. On a comprehensive level.

Also, do you know how the PLL reduction effects the processor? I hear it allows higher current to pass through or something? Idk.

i just know that lowering it to 1.72 ( intel's min amount ) would help.

The VTT voltage helps if you overclock the memory and BCLK. I've found it more stable bumping it up 0.020v with my memory overclock.

I dropped the PLL as it didn't need to be at 1.80v. and it was super stable at 1.70v.

Do you know if bumping the PLL down actually can have adverse effects on the chip?

Like... lower core voltage means lower temps, and overall less wear and tear on a chip. But with the PLL voltage being lowered, is that the same idea? Or does it adversely effect things in some way?

Most of the "in-depth guides" only touch on what each thing does.

afaik, lowering pll has been helpful not only on SB, but the 1366 i7's, and 1156 cpus

people report being able to lower vcore once they lowered pll.

also, having a high pll can cause instability.

Some people claim lower QPI/VTT voltage allows lower Vcore, but i can't confirm that. As for adverse affects, i doubt it. If it did lower stability then i would have crashed by now.

I run Prime 95 Small FFTs and LinX with 70% of my ram at the same time and i'm running strong.

same here. i've only tried 1.72v for pll and can run small ftts @ 5ghz no problem.

temps are lower...but by a few
