P2501 i'll continue to test. If you have some news please contact me via PM, we're on the same boat ;)

Since i also use the same Dominators 1600C8, is it possible to write down the sub timmings that you run stable?

Kinda worried about this board now, read all the pages. I also have OCZ 1600 6GB ram.

Thanks for all the links Eva on the first page, will have to read all those first :up:

cheapseats, what ram and Dram voltage are you running there ?

Eva, killer timings, what Dram voltage are you giving those Elpidia ?

Ok as you guys can see in the SPD window of CPU-Tweaker 1.1, the XMP#1 profile for the Corsair Dominator 1600C8 3x2GB kit has the profile for 800mhz (DDR3 1600).

The subtimings you will be interested in are

TRC-
TRFC-
TRRD-
tWR-
tWTR-
tRTP-

For this particular set of ram it looks like this....

TRC- 41 (Cannot set this in BIOS, max TRC = 31 in BIOS, is this an issue?)
TRFC- 88 (in BIOS this auto's to like 72)
TRRD- 6 (this was covered in a couple of the begin topics listed in eva's post, setting TRRD to 14 in BIOS results in actual TRRD of 6. This Thread for more info)
tWR- 12 (set AUTO in BIOS to 10, not sure how much of an effect this has)
tWTR-6 (again not sure on its effect on stability)
tRTP-6 (again not sure on its effect on stability)

I have also messed around quite a bit with RTL (round trip latency) settings, however its quite a daunting task considering every time I change a setting on VTT, it seems like RTL is changing? I read in the same thread discussing the TRRD that this was occuring.

I am finding more stability with 20x200 HT on and running RAM @ 1600mhz when I bump the IOH/ICH 1.1v voltage to 1.21, and have found IOH Analog Voltage to be of little to no use past 1.15v. (I am not sure how safe it is to run IOH/ICH @ 1.21v, but it certainly has gotten me a little longer before BSODs, so I will chalk it up to progress! Can anyone shed some light on the safeness of that voltage?)

EDIT: Going to try the new 6/19 BIOS posted in the BIOS thread, says

# 06/19 beta

1. Enhance the system performance

EDIT2: This new BIOS looks promising, my memory bandwidth has dropped a bit, however looks like Prime95 LargeFFT / 5300MB Priority 9 is passing further than it did on the 5/08 BIOS. Will report back fully when I see what else might have changed, I am gonna compare some stuff.

Forgive me if this has already been pointed out, I didn't read the whole thread:

So I've been using a Gigabyte EX58 EXTREME for a few months now, and I've been very happy with it. But I do not have an 8th expansion slot in my case to run tri-SLI with it. All of the GB boards have their PCIe slots arranged so that it you run tri-fire or tri-SLI using dual slot cooled cards...the 8th expansion slot would be required.

So I wanted to upgrade to tri-SLI, and was looking for a new board. I'd used the eVGA before, and thought it was pretty nice, but I wanted to try something new, and went for the DFI instead...oops :mad:
Link to the DFI board for reference.

The onboard sound option requires mounting in one of the rear expansion slots (the normal I/O area is used for cooling). Since I was going to be running tri-SLI, the only spot available is the top spot...PROBLEM IS THE RIBBON CABLE ISN'T LONG ENOUGH TO REACH THE TOP SPOT!!! Not only that, but since there isn't an electrical slot in that top position, adding an aftermarket sound card isn't an option either.

Bottom line, if you want to run tri-SLI on this board, the only option for any audio would be to buy a USB audio solution!!! WTF??? :screwy: Who the hell designs this crap?

I would try to find a longer cable, or email them to mail you one. This board is $300 bucks they should just give you one I would think...

Well mine gets here friday, cant wait to fight it with my OCZ ram

I keep getting this BSOD......

A clock interrupt was not received on a secondary processor within the allocated time interval.

Does anyone know what this directly correlates to? In terms of what voltage is too low or what might not be set properly?

I had that happen on my MSI X58M alot, needed more vcore.

My OCZ133MHZ CL7 (non Animal), would crash exactly after 4.49sec LinX each time, unless I set DRAM PWM switch to 15% decrease. Then it will pass LinX easily with exactly same settings on everything else.
My RAM can't run at 8x but the Uncore is at 16x.

I will ask that the "DRAM PWM Switch Frequency" be looked at. One should be able to leave this at Default for most overclocking. Also of concern is the reported memory bandwidth increase some are seeing when changing this setting. It is not possible for the switching speed of the supply to impact memory bandwidth. Something else must be changing behind the scenes when altering this value.

That's great, this setting seams to be affecting LinX, mostly. Everything else including Prime Belnd, Memetest 3.8, windows memory test, and all applications that i have tried would run without any problem with "DRAM PWM Switch Frequency" at Default.

It sames to be mostly related to something that would make LinX unstable (at least on my setup, and as far as i could catch the effect of this setting).

Does anyone tried 0619 beta?
It seems that 26 reboot issue is improved.
Can anyone confirm this?:confused:

thanks for posting this screen eva, helpful stuff :up: :)

1) i'm ~4-5s slower @ x16 uncore + same mem timings. looks like my OS is too slow atm for efficiency runs.
need x18 uncore + tighter mem timings just to keep up with your x16 efficiency.

2) second very useful thing is vTT/vDIMM for 32M.. noticed that your vDIMM was less than 0.1V > vTT.
so realised i could also reduce my 0.235V gap between vTT/vDIMM to run single 32M.
good news for my vDIMM levels :yepp:

Here you go mate :D

That's a direct setting from BIOS, direct cold boot to windows

ChaosMinionX, thanks for your post. I hope I find the time today to mess with the timings. IIRC at least tRFC was set automagically far tighter for me, will report back on that. Concerning that BSOD, it's core related I think, most likely VTT. That is was fixed these for me at least.

Oh one more thing...my machine stopped running PI recently as it keeps hard locking me....any ideas? LINX+MEMTEST+ORTHOS = PASS....

You're talking single instance? If so good luck. The board I have here has never been able to run a single instance of SuperPi at 190 or higher BCLK. Can run 8 instances just fine. I have asked that this be checked out.

very useful bclk ci2kla.. ;)

single 32M lock/freeze windows for me @ 220bclk was pcie.. < 110 = lock / 110 = 32M ok. but only tested 32M.

Seems I've found something interesting. Once I proved that I'll share to you guys :D

Hardocp just reviewed this board and gave it a silver but you can tell he hates DFI, he only seems to like those who pay for ads. (mentions no free review board and no ad support in the forums along with the bad customer support (I never personally dealt with their support but many have said its not the best)).

okay seems the freezing issue is pointed to the relation between VTT and vDIMM.
Here's the test.
vDIMM 1.65v VTT 1.28v CL8-8-8-20 2000Mhz -> 32M PASS
vDIMM 1.62v vTT 1.28v CL8-8-8-20 2000Mhz -> 32M FREEZE
vDIMM 1.65v VTT 1.34v CL8-8-8-20 2000Mhz -> 32M FREEZE
vDIMM 1.65v VTT 1.28v CL9-9-9-20 2000Mhz -> 32M PASS
vDIMM 1.62v VTT 1.28v CL9-9-9-20 2000Mhz -> 32M FREEZE

I'll say from this test my chip doesn't like VTT to be too close to vDIMM...:shrug:
