DFI X58 - i7 920 max bclk on AIR = 230Bclk

[eva2000]

Max 230Mhz BCLK

I had all but given up after I found my initial max Bclk 32M Pi stable BCLK of 220Mhz with tight 878mhz 7-7-7-17 timings.

But I'd like to thank Hazzan (233BCLK) and Solarfall (230BCLK) for their inspiration with their DFI UT X58-T3EH8 max BCLK attempts as this prompted me to keep working at it

After numerous bios reboots and trying looser timings and a few voltage combinations, I finally surpassed my previous max memtest86+ v2.11 bootable BCLK of 224, moving all the way up to 230-231 memtest bootable.

Enough for a quick boot into windows for a CPUZ Validation at least

[Solarfall]

kick arse !!!!.. im sure there is room to improve from there keep pushing it eva

[loonym]

Once again, great job! Can't wait to see more. Makes me glad I ordered one of these to play on.

[xoqolatl]

Excellent result! this DFI board is looking really nice.

[The-Fox]

Wow, eva that rocks !!
I thought solarfall was just plain lucky !
Can you guys put the finger on the setting which made the change ?
If solarfall did it and eva2000 did it, there is something this i7 suckers want to get some more bclk...
Either that or i7 just looove DFI boards.

[Hazzan]

Nice George Finnaly you get awesome result......keep pushing

[eva2000]

thanks guys.. will be pushing it more - aim'ing to break my previous max 32M pi on air of 4610Mhz 21x220 (bclk limited) hehe

[The-Fox]

OK eva, there is definitly something about those settings :




In the past I never got post on anything above 223Mhz.
Now I got windows to load at 224Mhz and Used SetFSB to go up to 228Mhz, 229Mhz and above just freeze on me.

The settings on my ASUS are a bit different but it kind of has the same effect I guess.

Congrats eva/solarfall , now i need to run with DryIce again

[eva2000]

Nice... thanks for the confirmation !

Going to see if my mixed Samsung HCF0 3x1GB kit will handle 228-230bclk with 10 mem multiplier LOL

[SAE]

Now it's confirmed. Finally! Thanks George.
I'll try that as soon as I get my board (wonder if it's still at German customs ).

[westsider]

i have got 4350MHz with box cooler

i am just waiting for lga1366 bracket of EK supreme

nice westsider

no probs.. more to chew on

Max BCLK Super Pi 32M Benchable

Triple Channel CPUZ Validation @229Bclk
Haven't pushed ICH 1.5 Voltage yet like I did for 230Bclk, so that will be next up for testing.



QPI Frequency = 4123Mhz!



Super Pi 32M
Ignore the times just testing with loose timings. Higher Bclk do require more vdimm that usual due to QPI ceiling. Without enough vdimm DFI post diagnostic LED = CF code for lack of vdimm voltage.

@226Bclk bios set - QPI Frequency = 4063Mhz



@226Bclk setFSB windows set - QPI Frequency = 4074Mhz



@227Bclk - QPI Frequency = 4088Mhz



@228Bclk - QPI Frequency = 4110Mhz
- had to bump vdimm, vcore and CPU VTT Special percentage added
- either a bad run, or lack of volts for either vdimm or CPU VTT or both led to slower 32M Pi time ?

Max BCLK with 10x Memory Multiplier
- limited by memory max overclock frequency

Now to try max Bclk frequency with 10x memory multiplier - ultimately will be limited by how far my memory modules can overclock

Interesting that up to DDR3-2263Mhz system registered 3x1GB Samsung HCF0 unmatched modules as triple channel, but when I hit DDR3-2298Mhz, windows reported dual channel instead of triple channel ?? Not enough volts somewhere or maybe my 1GB G.Skill PC3-12800HZ module can't keep up with my Corsair DDR3-2133C9DF modules ??

i have finaly achieved 4511MHz with water
and 4471 superpi stable

if i go above something starts to scratch on the board
some sound like condensators were going to blow out
i have watercooling and temperature is at about 45 celsius with 100% load and 4400MHz

water is very low cooled


eva do you have some idea?
is my board OK?
or if i try to start with 1.6v+(cpu temp is under 50 celsius) it has the same sound from the board or somewhere from socket-pwm area
and sometimes it shuts down if it goes up to loud

[eva2000]

congrats on 4511mhz!

sounds like condensators ???? not sure what you mean ? i can't hear anything as i have my push and pull fans on TRUE120 at full speed along with fans over NB and ram.

You have HT enabled or disabled ? past 4473mhz for me and i need to disable HT with TRUE120 air cooling.. maybe same with water ? what psu you using ?

[before]

Excellent George!

[westsider]

i use 1100 watt piperock


and i have found the problem


i have cold kathode lights
and they are surrounding the whole board


i took the top one away and soud is gone

if i try to put this kathode somewhere over socket everything goes out

weird stuff heh

[FragMagnet]

awesome results ! so how much of a gain is the DFI over the UD5 ? I haven't been following when you made the switch

[eligray]

did you somehow dump those setting from BIOS into a text file? If so, how?

DFI's really are the beast

DFI UT X58-T3EH8 is my first and only X58 ever used... haven't had the privilege to use other X58 boards yet. Waiting on Gigabyte X58 that has been promised since before Xmas so will wait till whatever X58 is sent my way for comparisons and tests

DFI UT X58-T3EH8 is alot of fun and glad it's gave me a good first impression of what i7/x58 platform can do

If DFI can fit into their next bios what I asked for, maybe we shall see even higher memory clocks with non-elpida ic based memory (and maybe bclks).

nah used my own made bios template available at http://i4memory.com/f80/dfi-lp-ut-x5...emplate-12919/ and filled in my settings used myself

Sorry about that, mem is failing me with age ! I confused you with dinos22, which brings me to the next question, how did you Aussies hijack all the golden i7's ?

FYI, my i7 920 3836A756 was the very first batch that arrived in Australia and AFAIK i7 sales in general weren't selling well and was available for quite a while before I nabbed 2x i7 920 3836A756 (will test 2nd one very soon - fingers crossed it's as good if not better than this one - need 2 so can test 2x X58 boards simultaneously )

Maybe being first shipment, Intel didn't bin their first batch of i7 920s as tightly as they do now ???

[dexster]

super results ... once u consider the heat generated by the i7 , its summer in australia atm AND this is air cooling... its amazing

its just eva .. hes got insider knowledge and hes not telling

damn luck guy you are


great as always :P
