What PCI-Express frequency are you using? And how much did it help?

215x21 is 10-run LinX-stable with PCIe=100MHZ .

I haven't done much testing of PCIe-effect with x21 multi, but have done some with x19 multi and:
PCIe=100MHZ .. BCLK221 boots and 221x19 is 24/7 stable too, but BCLK222 won't boot here.
PCIe=104MHZ .. BCLK222 boots and 222x19 is priemstable too,
PCIe=104MHZ .. BCLK227 boots fine and 227x19 runs some light load too, but won't get primestable, and increasing the PCIe up to 115MHZ won't help either. (This may work on other systems. I suspect this limitation is related to my double GPU (GTX 295), because i get some display-artifacts while priming with BCLK>226). I haven't tried BCLK>227 yet.

All these test are done with LLC= "Level 2", just started testing with "standard" and now the 224x19 is showing good promises for primestability with PCIe=103MHZ. This is 2 BCLK higher than before, but I'm not so very sure if this is stable, or the LLC is the reason, yet.

Woah so increasing the PCi-E clock helps the overclock? If so I think I might have 4.5 GHz in this chip.

Only to break the 222bclk barrier. Below that nope.

I think that increasing the pcie will help max bclk with any 1366 cpu regardless if your max is less or more than 222.

[Intratech]

Cheers, I'll give it a go and see what I end up with.

[Intratech]

Oh yeah, I noticed with the F3K BIOS my memory won't overclock as high as it used to do with the F2 BIOS.

[Sam_oslo]

Some quick tests to see how it works with LLC= "Standard" and looks good.

It is a huge Vdroop(compared to Level 2), Vcore= 1.30625 (BIOS set) ends up as 1.24v/1.21v (Idle/Load). But I'm keeping it, not only because stopped wining, but seams to be running stable with 2 higher BCLK

PCIe = 103MHZ, not only boots with BCLK224, but also seams to be stable roo

w3520 @4.25GHZ (224x19) 1.21v 30 min OCCT stable

Some update on this ...
This is not stable .. Tried with Vcore up to 1.232v and VVT up to 1,34v, it runs some OCCT and Primes too, but Linx freezes after about 2 minutes at almost same spot every time.
Tried my good old profile @4.22(222x19) 1.2v and it is passing the spot just fine.I can conclude that: The LLC= "standard" is not resulting in higher BCLK on my setup.

Weird. About 6 minutes into Prime Blend my screen flashed to black then came back pretty quickly. Anyone know what this means?

edit: Still going strong for 20 minutes... gonna stop it now so I can game

206x21 = 4326... max temp is 84C. Running very stable for all my usage... this is longest Prime session I've done though. I'm still wondering about the screen flash, I don't have my PCI-E overclocked at all either.

---------
edit 2: whoa I am running Linx now. I have 12GB of RAM now and am running full problem size at 37162... first run took 10 minutes!!! Wtf, is something wrong? My Gflops is 55.4136, is this low for 4.3ghz? Hm, 2nd run was 55.6235 Gflops.

Also max temp during Linx is now 88C. Anyone think I'm doing serious damage to my chip?

lol, I just realized how many questions I'm asking here. Any answers are very much appreciated guys! <3

Is there a way to check temps on the NB/SB? Someone mentioned Everest, but I couldn't find temps on the Ultimate Edition. Thanks.

try Hw monitor, but you have to guess the cpu,NB, and system temp

great result angkies :up

[Pickles24]

Thanks nyeah for the info, I take it TMPIN2 would be the NB.. After doing a little testing the Hybrid Silent pipe(with a 120mm blowing across the fins) takes off about 6-8c. I am going to see what the stock block can do under water this evening.

now2 highest bclk i've seen here

These are really good results with high BCLKs.

Can anyone point me to where there are release notes for these things?

[OC Nub]

I am trying this new bios.

The 2:10 memory multiplier requires a lot of vtt, more than I am comfortable using. I have been messing around the different memory multpliers on this board and my UD6 P55, the 2:8 is faster in spi1m. The vcore is high but I turned it up to prevent it from crashing while saving this image. This is as high as I can bench at cas6 on the x58.

[jacek]

f3m - have not noticed any changes. I'm still having a problem with bclk above 215. I do not know what's going on

This is very strange. I have not problem with bclk 230:

I'm getting almost the same, but mine is with unoptimized RAM and loose timing.

[OC Nub]

^ Doesn't look like there is any real benefit to try for low latency. Our scores are almost the same.

Damn your vcore is good, makes me want to get another chip. I keep looking at that 960 chip at newegg but cant make myself press the button.

[Sam_oslo]

I'm afraid you are right. It seams to give "almost" same Everest-bench-numbers with x8 RAM, no matter what latency, too.

Yeah, I love the low Vcore too, but this is far from stable, and my air-cooling can't handle the necessary Vcore to stabilize this for 24/7 use, either.

Waite for i7 930 before pressing any button, it will be here next month. It will probably be a new stepping with better OC headroom. Just some guess and speculations from my side for now, but we will find out soon.

This result makes no problem with BIOS F3k:

But with f3m situation is not good

[Sam_oslo]

I noticed my 8-hoers prime stable @4.22(222x19) 1.2v couldn't Prime for even 1 minute with the new BIOS (f3m).
I haven't tried my other 24/7 profile @4.51(215x21) 1.34v, or that 220x21 with f3m, because I've already flashed back to F3k.
