I think others ran into the same issue with never platforms, might have been @Aleslammer maybe?
-
Got 2.4 MHz over my previous best by messing with the clockskews. There is still more to this chip, even at ambient, but I'm lacking control over some settings to get there. Looking forward to what its capable off under Dice - 1 week to go!

How much would shipping be to Germany for the EX58-UD4?

I mostly binned low end xeons (because thats what I could optain in bulk for cheap), and the C batch seems to be able to reach high bclks (271 at ambient is the highest I‘ve gotten so far, with maybe 30 c batch chips tested), core clocks were, with the couple chips I tested for core clocks, pretty similar to A and B batch (only had a couple of those though). Taggs chip here is a B batch but he has a similarly clocking C batch. If you want my bclk binning data shoot me a PM
If you want to test a couple low multi C batch chips feel free to shoot me a PM about that, I‘m sure I can arrange that...

Are those Xeons 3xxx (single QPI) or 5xxx (dual QPI) series?
I've recently dug through many old Gulftown OC threads but couldn't find any examples of single QPI chips (such as i7-9x0 and W36x0) needing less than 1.36-1.38V for full stability and/or 1.28-1.30V for 32M at 4.5GHz (extrapolating from other clockspeeds at 0.04V per 100MHz). I also wasn't able to find any such chips myself on a few dozen A0 / 3005F chips that I tried over the years. So I guess the dual QPI chips are better on MHz/volt due to having to meet stricter binning requirements induced by the second QPI bus.
I'll note that this is my binning data (binned about 50 32nm Westmere 5xxx xeons or so) and not Taggs, and these are the best of those, though my main goal was binning for max BCLK (that chip is actually not included here as it clocks worse). There might have been some better chips I missed but I wasn't aiming for max clocks at ambient
(last 2 are Uncore/RAM freq for superpi 4m as I was only testing these quickly. If you want I can do some more detailed testing I can do that later this week on the E5649 and 270 E5640)
I'm binning at 1.4V Core/1.4V QPI at ambient with a weighted down aircooler. All three of these should about manage R15 at around 4.5 with 1.3V.
The E5649 is 100% stable at 4490 Core/3814 Uncore/4040 QPI/890 MHz with 6 DIMMs with 1.344V Vcore, 1.3V VTT, 1.65V DRAM
(used as a daily, actually degraded at some point, was better before). I've heard of a couple x5675s being 100% stable at 4.6+ with under 1.4V in daily systems.

Dat CPU... What can it do on air and/or for Spi on LN2?
1.3V for R15 at 4.5 GHz I've heard, not the rarest ambient clock (I actually have at least 3 xeons that can do that, but those will be multiplier limited)

Only single core GPUs are allowed!!
That's all that needs to be said. Else we might as well dig out our 295X along with the 9800 GX2, GTX 690 and HD 7990... If you aren't sure about something being allowed, PM Leeghoofd before the comp starts - he won't leak your idea so nothing to worry about there.

Nice score! How is that CPU at ambient? Also max BCLK?
-
Free push as something arrived:
Thanks! Can’t wait to try it

Board doesn't like 1T RAM?
Not that it would matter much in CB
Shouldn't be an issue on the Rampage II, at least not on mine. Runs 1T on everything I've thrown at it

If you really think that then you are on the wrong forum.
PS: I just flashed a FM1 board 20 times. Seems like I'm crazy in the coconut. ?
Well its not your board right? ?

No, but it is not needed for anything but GPUPI... so waste of time in my book. Also the risk of bricking the MB is always there if something goes wrong.
FM1 isn't needed for anything but GPUpi here either... Its not a particularly valuable platform regarding points.

can you take a pic of the x58 ud4s socket with the broken pin/did it still work with the missing pin?

I'm surprised you even got this far. X58 usually doesn't work on LN2 at all unless you run FSB at near 200. Usual multis for 980X are x31 or x33 in such a case.
32nm isn't that problematic with LN2 as far as I've observed - Jokot was running about the same BCLK at -120°C as on ambient on his x5650 (also managed about the same bclk on ambient, off course nowhere near the same bench able frequency). Gonna put my own stuff under dice soon, my 269.65 BCLK (under air) E5649 is gonna need that...

Why pick this slot? I'm just asking, I have no idea about memory binning lol
I'm only speculating here, but I would guess you only have interference coming from one side (the other slot) unlike the other slots which also have the traces towards the further out slots on both sides.

So how much for the Mobo? Is that price for mobo and 980X?
Its a realistic price for the board alone and there is no 980X listed here.
-
How good is that CPU at ambient? I know it doesn't mean everything under cold, just curious :D
-
Added 9800 GT DDR2
-
Ryba pot still available and shipping to Germany?
-
Is the price per stick or per kit?
-
Any that can do ~740 MHz+ with loose timings? Or am I looking at the wrong IC for that?

Does that say 2012 0_o
Maybe its a tweak? Maybe he accidentally reset the clock on the board?
