post #8841 of 19539
Is there a software monitor for pcie bus speeds? I have z87g45, i dont see any pcie bus speeds..

Nvm, i just saw a reply

Good luck.
If you're going to do Prime-or-Die and you want to push for next multiplier, yea, you're going to have to delid. Keep in mind though, I'm at 1.42v on air nondelidded. BTW, just in case, what is your eventual input voltage? It probably isn't going to be a significant factor for that low of a Vcore, but doesn't hurt to make sure it's not some off the wall value, just in case.

so i should set the cache at auto?
ill check it when i get back to home at work atm xD
forgot to ask i set core voltage at manual 1.280v why does it read at 1.296v at cpu-z?

Set the cache to Manual: 34x with 1.2v.....thumb.gif

I'm not sure what the reason is for the discrepancy in vcore, but it seems to be a pretty normal thing for Haswell....

vcore target will be 0.02 more than you set in bios

and i like 1.15 for 33x, since 1.15 is already excessive, 1.2 is pretty crazy. I'm also paranoid of setting ring above vcore since there's a few warnings for it in different places, but not sure if they hold any weight

and 33x, because 34x = turbo on 4670k, 35x = turbo on 4770k

Does bclk strap adjustments mess with pcie slots frequencies?

I am aware that RAM,CPU,and Cache multipliers are affected by these, so i am making sure about pcie slots before i start tinkering. Any advice would be appreciated!

Adjusting the bclk does change the pci-e frequency, although I've never met a piece of hardware that wasn't OK with at least 109 bclk (HDDs, SSDs, GPUs), all my gpus & HDDs were OK with more, 1 SSD flaked out at 110 bclk before.
Using the strap doesn't change change the pci-e frequency, although how well it works depends on the boards bios', I've had bad instability an a board at 125 strap with one bios, different bios 125 strap worked great on the same board.

I come from fx-8120. Haswell requires very fine tune compares to fx. In amd i put vcore until not crash. In haswell you must play around vcore and vrin. For haswell, Adding vcore alone doesn't help stable the oc without right amounts vrin. I am catching a behavior on my chip right now.

Very correct on this, I should've checked which CPU was being used before I mentioned that....

Did you establish a base line? I Like a stable value?

4.7Ghz stable @ 1.375v - i need 1.53v to get 4.8Ghz

What are some of your other settings for your 4.7GHz? I want to get to 4.7, but i'm stuck at 4.6.
