I have 2 questions ... EVA ... how did you get the Everest beta version1227? I have the 1226 version, yet I can't find the one you have ...
Two, does anyone know why in the BIOS under Advanced Chipset Features > PCI-E compliancy mode ... it shows the version to be 1.0a ? I thought it was supposed to be 2.0 ... anyone notice this?

From everest support forums No idea on PCI-E version mode

EVA - re your post #562 ... you say you did that with Crucial Ballistix PC2 8500, yet your CPU-Z shows OCZ PC2 6400 ... I have 4GB OCZ PC2 6400 and a E6850 ... if I use those settings, I should see something very similar to yours, right?

re-read screenie no OCZ listed in 666mhz 5-5-5-9 screenie. As to settings they might differ as no set of memory modules or board NB memory controller are exactly the same. Really folks shouldn't focus on the resulting end settings but the process itself that is involved in getting to them

nice one Eva! is it ok to push NB to 1.6v?

for benching only.. for everyday it's easy to drop NB volts needed by loosening your memory sub timings and additional tight tweaks i.e. clock crossing and clockcommon settings drop down from More Aggressive

.. re-read screenie no OCZ listed in 666mhz 5-5-5-9 screenie. As to settings they might differ as no set of memory modules or board NB memory controller are exactly the same...

The CPU-Z validation page you used shows at the bottom left hand side in slot 1 and slot 2 OCZ Technology ... that is what I was referencing ... but what you're saying is that the 666MHz 5-5-5-9 is from the Ballistix RAM, right? I was just trying to clarify what RAM did what ... that's all

[Brother Esau]

Anybody running the New Cards in Cross Fire yet?

huh? i see both slots saying crucial

[Brother Esau]

ooooh you have some cards don't you Eva

[eva2000]

ooooh you have some cards don't you Eva

Yeah will test later but they're in my Blitz Extreme rig for now while i figure out DFI X38's memory oc'ing behaviour first

[Brother Esau]

Thanks George I can appreciate that

2x3850 crossfire, yep

Again clock fine delay and controller fine delay tweaking allowed me to stabilize my 2x 1GB Crucial Ballistix PC2-8500 @585Mhz 4-4-4-5 PL 5 at 2.51v.

• 540mhz 4-4-4-5 at 2.23v = okay
• 550mhz 4-4-4-5 at 2.31v = okay
• 565mhz 4-4-4-5 at 2.38v = okay
• 575mhz 4-4-4-5 at 2.45v = okay
• 580mhz 4-4-4-5 at 2.47v = okay
• 585mhz 4-4-4-5 at 2.49v = 4 errors in 1st pass of test #5 memtest86+ v1.70 loop
• 585mhz 4-4-4-5 at 2.51v = okay (manually set clock fine delay from current 3 to 4 and control fine delay for DIMM 1 + 3 changed from current 10 to manually set 11)

Someone with this board + Enermax Liberty ? I`m curious if this incompatible was resolved .. Thanks.

don't think it has been resolved.. get a new psu

Don't know about the Liberty but the Galaxy appears to have issues.

[M3kk]

Well i have 4 psu s now, but i want to put the liberty in the case with this board or with a p35 one, but the p35 have issues with liberty, and i dont know yet about this .

Op1000 and zeus1200 wont fit in my case .

Praz, yes i know about p35 and liberty, but maybe was resolved with this board..
I`m curious if that adapter will resolve this problem, would be nice .

[eva2000]

OP850 or OCZ 1KW ProXStream both will fit in a case

[Praz]

Praz, yes i know about p35 and liberty, but maybe was resolved with this board

Wouldn't bet on it. The power planes are almost identical. There is mod that will allow most of the power supplies to work with different degrees of success although it is not user doable. I will check if the X38 has been altered in this fashion.

[lazy]

so i have been unsucessful priming my cpu for more then 10mins
Do the Q6600 G0's need that much voltages or am i doing something wrong?


FSB = 400
Multi = 9
Vcore = 1.48
VVT = 1.6
NB = 1.5
SB = 1.74

GTL set according to the link provided to be a few pages back

That GTL Reference link is just that, a reference. Board to board variations may result in the settings being off 5 or so points in either direction. Also the tables show the values needed for a 67% setting. Most quad-cores, when being overclocked, prefer a setting closer to 70%.

[M3kk]

In my case not . The Liberty 500 fits with mm, so if i want to put there a psu bigger than the liberty with 1 cm, then wont fit .

[M3kk]

Response from enermax :

Im afraid there is no solution. The adapter is for the Galaxy series only.

There is no fix that we can apply to this PSU that will fix this issue as it is related to DFI’s motherboard.

The only choice you have is to change PSU or Motherboard L

Ah that suxs then.. new case for Xmas ?

Clock Fine Delay At Work Continued....

Swapped out one set of 2x 1GB Crucial Ballistix PC2-8500 for another set of 2x 1GB Crucial Ballistix PC2-8500 since I'm re-testing all my memory on DFI LP LT X38-T2R to find the best matched pair for this board

Seems similar process to gain stability occurs with this set too - meaning fine tuning clock fine delay DIMM 1 + 3 as well as controller clock fine delay allows this memory to fly as high if not slightly better than the first set I tested.

• 633mhz 5-5-5-9 at 2.27v was okay (with lower NB 1.566v volts)
• 640mhz 5-5-5-9 at 2.27v was okay (with lower NB 1.566v volts)
• 651mhz 5-5-5-9 at 2.31v Froze at 88% 1st pass of test #5 loop (with lower NB 1.566v volts)
• 651mhz 5-5-5-9 at 2.31v was okay now by increasing dimm 1 + 3 clock fine delay values from Current (2) to manually set 3. (with lower NB 1.566v volts)
• 660mhz 5-5-5-9 at 2.42v was okay - dimm 1 + 3 clock fine delay values still manually set to 3. (with lower NB 1.566v volts)
• 666mhz 5-5-5-9 at 2.47v would error out in test #5 loop - went to check bios clock fine delays that are set automatically (Current values) and they all automatically shifted down from the values that were stable at 660mhz 5-5-5-9 at 2.42v). So applied same theory I discovered with DFI LP UT P35-T2R, I manually adjusted the remaining Current auto values @666Mhz to the ones matching @660Mhz 5-5-5-9 stable clocks except the Dimm 1+ 3 clock fine delays which manually set to 6.
• 666mhz 5-5-5-9 at 2.47v with clock fine delay values of 6-6-10-7 / 6-6-10-5 for each channel respectively allowed me to loop Memtest86+ v1.70 test #5 for 10 passes before 2 errors occured. Still not quite there but better than before. NB volts still at 1.566v
• 666mhz 5-5-5-9 at 2.49v was okay with NB still 1.566v
• 669mhz 5-5-5-9 at 2.47v with NB raised from 1.566v to 1.617v and manually set clock fine delay values to 6-6-10-7 / 6-6-10-5. Ended up with 3 errors after the 4th pass of memtest86+ v1.70 test #5 looping.
• 669mhz 5-5-5-9 at 2.49v with NB = 1.617v. Decided to try manually setting clock fine delay values to match 1st set of memory's 666Mhz 5-5-5-9 32M stable settings which are 7-7-11-8 / 7-6-11-6. Resulted in 4 errors after 2nd pass of test #5 looping.
• 669mhz 5-5-5-9 at 2.51v with NB = 1.630v and CPU VTT = 1.387V raised from 1.377v. Clock fine delay set at 6-6-10-7 / 6-6-10-5.

then what would you recommend?

[M3kk]

No man I dont use case, i just want to put this board or the p35 one in the case for 24/7 .
I have a modified Cheftec case, with dual rad at the top, because of that wont fit other psu . http://mekk.homeip.net/cpgallery/thu...s.php?album=12

Eva, can you try max 4-4-4-12 ?
Do you have teamgorup or cellshock kits? Or praz, you know if the "issues" with this rams are resolved?

[Praz]

then what would you recommend?

At this point I don't have a recommendation. Haven't had time to explore GTL values yet. I don't known at this point if the settings can even be carried over from the P35. Will probably get into it this weekend if I switch over to water. With air cooling I can't get to the MOSFETs to measure the voltages

The set of crucial pc2-8500 i tried before this did 585mhz 4-4-4-5 at 2.51v http://www.xtremesystems.org/forums/...&postcount=587

Have yet to test this set of crucial pc2-8500 for 4-4-4-5 yet.

Yeah i have old school Team 6400C3 Micron D9GMH does 570-575mhz at 2.4-2.45v on P35 chipset. No cellshock DDR2 though, Cellshock DDR3 kit coming soon though for DDR3 boards

[Praz]

CellShock 8000 on this board acts the same as on the P35. After messing with the SPD it seems like a lost cause. I'm almost willing to bet money it's a PCB issue.
