What would happen when you compare strap 400 2:3 vs 5:8 vs 3:5?
If it's not bugged then 2:3 < 5:8 < 3:5 in terms of speed, but if it's bugged then 2:3 ~ 3:5 < 5:8, isn't it?
Well，if FSB and Mem freq is almost the same, then I think mem performance should be strap 400 ＜ 333 ＜266 ＜ 200. But if FSB and Mem freq scares too much, things will become complicate.

Well the EP45T-Extreme definitely has this bug.
THX for the info.

I did some memory bandwith test by AIDA64, I don't think it has 3:5 bug for my EP45T-UD3R
1. E8400 (500x6), 400 strap, div 3:4, DDR3 1333 6-6-6, PL9
2. E8400 (500x6), 400 strap, div 3:5, DDR3 1666 6-6-6, PL9
3. E8400 (500x6), 333 strap, div 5:8, DDR3 1600 6-6-6, PL9

We all know that P45 has memory div 3:5 bug, but I still wonder:1. Does this bug exist in all P45 boards? For exmaple, is in all DDR2 and DDR3 board? is in all chipset rev. A2 and A3?
2. If not all P45 board have this bug, how can we confirm that when we use 3:5 ?

not until 320+ BCLK by wytiwx
Hahaha......no thx man, it's quite enough to keep crazy by LGA775

that board for sure is getting a workout
Great job!
Well, CPU is the key you know

The highest percent overclock that I'm aware of is this one: wytiwx's 4657.99 mhz with Intel Mobile Celeron 1.2Ghz
My percent overclock score is for Intel or for BCLK, the really highest percent is donw by AMD up to 300%+

again confirming my suspicion that either me or my mem is the limit, I’m willing to blame the mem, for now at least. Tested 4 boards (3xud3p, 1x ud3) now, 3 confirmed 725, last I only tested with a random chip which walled at 710, though I still had >0.1V range on vmch so doubt the board was at its limit
If you don't have good D9GMH, maybe you can try those crazy nanya d-die
just kidding

Crazy mem. Are you really sure the IC is nanya? Have you removed the heatsink?

Go go Wytiwx. Go for the first place on all CPU Freq.
hahaha, that would be a very big project which need all the OCer s.

You did 730MHz on a Wolfdale 3M?! ?
Yep, actually two E7200 hit 700 FSB by now, both are Wolfdale-3M, not from Wolfdale-6M

What voltage is the northbridge at? Also, nice job! makes my 5.2ghz OC look pitiful lol.
Vnb 1.50V

updated 266 bus speed CPUs which did 700+

Coming back for more soon? Or do I and others have to try harder first?
You 750+ FSB first

Thanks for this! Did you find any difference single vs. dual channel and between the different slots?

Useless to bench that nb on cold. My P5E3 Pattaya board would do 7g with just NB on air easy. An insane validation score anyways.
yeah, your P5E3-P board is more crazy

Nice! Time to break 7G...
I believe other people will make it from TaPaKaH's treasure mountain

I had E3200 with 6M core, but was dead
I got only one E3200 from Wolfdale-6M, but no OC surprise. And I have several E3300 from Wolfdale-6M, no OC surprise too.

For E5x00/E7x00 you need PLL under the default 1.5V, which only Gigabyte P45 and PLL-modded boards can set.
Without PLL mod, the current #1 E5200 stops at 390 air, 480 LN2.Also, you can immediately discard Wolfdale-3M derived ones (96-98%) and focus on Wolfdale-6M ones. You can distinguish these physically.
I've tried around 50 of the latter, which would yield same results as 1000++ random ones.For me, PLL<1.5V made worse CBB first, and worse CB sometimes.
Generally speaking, E5200 from Wolfdale-6M work better than Wolfdale-3M indeed.

This is still very lucky
I tried 1500-2000 pcs E2140, E2160, E2180 and my best chip did 565 LN2.
We all know that FSB wall is really a bi*ch, I tesed ~1000 pcs E5200 and still no go for 500 FSB
about P45 chipset memory div 3:5 bug
in General overclocking

Is mem bandwidth of 750MHz/DDR3-1500 the experimental results?
But in other words, if we have to use 3:5 for efficiency rather than raw mem freq in particular conditions, it doesn't matter whether there is a bug or not.
