Got some new goodies today

nice but why not a 48xx so u coulda gone crossfire

[mikeyakame]

Funny thing, I realized a few days when I installed my Thermalright HR-05 SLI/IFX sink on my LT NB that 1) I had to mount the 80x25 fan on the PCI-E slot side because the wireclips interfered with my TRUE, so I used them back to front to mount the fan like a diamond! and 2) The HR-09U VRM heatsink wouldn't clear my 38mm fan on the IO side of my TRUE!

[spinejam]

opinions appreciated: is the x48 LT version better than an asus p5k-e p35 mb?

[Shiranui Gen-An]

Playing with GTLs I managed to get he board to POST at 534FSB, but I had to jack up the NB volts quite a bit (1.61V) and I'm only running 1:1 333/667. Doesn't seem like I'd need that much vMCH...

if you gonna do crossfire only and you need 4x1 memory clocking
your board is good enough
i honestly prefer my ut p35

[The Water Dog]

Looking forward to hear how much juice you can push out of that fruite Shiranui

[Beefy22]

Maybe you guys can help me out here...

Yesterday I finally had some spare time and decided to replace the stock NB cooler with a Xigmatek porter n881, as well as reapply some new AC MX2 and replace the pushpin mounting hardware for my Xig s1283 with a bolt thru kit...

After cleaning, applying TIM, mounting the new HW and reconnecting everything(or so I thought) I booted up the PC but was confronted with a LED code of 88. Like a dumbass I had forgotten to put the memory back in, but even after I did put the memory back in I still have an 88 code. I even went as far as to pull out the cmos battery overnight but nada.

So my question(s), what could I have possibly screwed up?

- corrupt bios?
- killed the NB?
- something else???

I appreciate any help/suggestions!

take out battery for a while
just needs a reset
if it didnt work take v-card cpu out too

Try plugging in PS2 keyboard, and hold down insert then power on, dont release it untill it powers off or you see HDD led flash. Sometimes also turn off PSU for 10-15sec, then turn on and do same thing. Sometimes requires few tries but usually gets it going. Try one stick of ram also and make sure that the bolt through isn't too tight.

I've got a Thermalright HR-05 SLI/IFX on my NB with bolt through mounting and I haven't had a problem. Using OCZ Freeze Extreme thermal paste which I figured I'd try for kicks and it's impressed me quite a bit. Much better than AS5 and no set time.

That should do a full cmos clear. It usually works for me when nothing else works.

I removed the vid card in conjunction with pulling the battery out then let it sit an hour or so and bam it works again... But IIRC post code 88 means NB and/or power issue?

All's well, I really don't care about the why, just glad my computer is back up and running(thanks to AC MX2 + Bolt thru kit and new NB several °C cooler too).

Thanks for the help! :cheers:

I didn't get to try this one out but next time I need to do a clear cmos I'll give your procedure a try... Thanks!

glad it worked
btw same happens to me every time i start playin with my board just needs a reset

[johnysb]

any help with powerchips drive strengths?

[BulldogPO]

What is best bios for this board?
For Quad overclocking.

[mikeyakame]

any help with powerchips drive strengths?

with my gskill pc2-8800 2gb sticks, which use PSC ics.

I'm using slots A2/B2 as I find they give better delay locked loop skew values on detection with right DLL model.

For my sticks I found the following worked best.

CK Drive = 5, DQ Drive = 7, DLL CH1 = 5, DLL CH2 = 5

Fine Step Degree = 30ps

Ch1 Cross Clocking Flight Delay Skewing = Aggressive
{
Dimm 1 Fine Clock Delay = Current,
Dimm 2 Fine Clock Delay = 15 degrees (450ps),
Dimm 2 Fine Control Delay = 23 degrees (690ps),
Dimm 1 Fine Control Delay = 22 degrees (660ps),
Channel Fine Command Delay = 23 degrees (690ps)
}

Ch2 Cross Clocking Flight Delay Skewing = Aggressive
{
Dimm 3 Fine Clock Delay = Current,
Dimm 4 Fine Clock Delay = 16 degrees (480ps),
Dimm 4 Fine Control Delay = 26 degress (780ps),
Dimm 3 Fine Control Delay = 25 degrees (750ps),
Channel Fine Command Delay = 26 degrees (780ps)
}

Ch1+Ch2 Common Clock = Aggressive


You can try this arrangement too as it works pretty well off the mark.

CK Drive = 4, DQ Drive = 6, DLL CH1 = 6, DLL CH2 = 6

Heres a pic of my LT T2R build!

What is best bios for this board?
For Quad overclocking.

I'm very happy with ADC24 bios, DFI needs to add CPU and NB clock skew adjustment and the T2R will have a perfect bios. They included Cpu Clock0/Clock1 Skew in the T3RS bios, and having got Asus to add those options to the Rampage Formula bios without hesitation upon request I'm sure DFI would do the same if enough of us wanted them

[Shiranui Gen-An]

You always mention the 4x1GB clocking on your X38, care to share your settings?

[johnysb]

thanx for ur response mikeyakame,no luck with my mems though.
I am trying for 9*460 5:6 agressive,fast/fast.
My mems are on my sig,Tring with 2.15-2.2V@ rams, -1.45 @nb with no luck ,i do get about 80 errors in the first loop of test5@ memtest.
I was stable @9*460 with 4:5 with my 4*1 ballistix, so i know that the only thing that is messing with my patience is those mushkins.
Any more ideas?
Thanx for your time!

Try.

CK=4,DQ=6,DLL CH1=4,DLL CH2=4.

If CH2 CMD or Control come up as < 100ps, means delay wasnt autodetected correctly. Best thing to do in this case is, boot with 6/8/0/0, save and reboot, then change to 4/6/4/4.

Take note of the differences between CH1 and CH2 for CLK and Control Delays between Dimm1 and Dimm3 or Dimm2 and Dimm4 which ever you are using, and when setting your own delays take that difference into account.

On my board I have about 35-40ps between CH1 and CH2 clk, 130ps between CH1 and CH2 control. Command delay is safe to set same as Control Delay for that channel on slot with memory.

Edit:

Just doing testing with my new Q9550 and these PSC g.skill sticks. Trying to not change skews manually and find dq/ck/dlls that match up without changes. I've tried a few combinations this afternoon so far the one I'm using right now is faring excellent.

DDR = 1066, 5-5-5-15, 2N cmd, MCH ODT = 2, tRFC = 48, tWR = 14, tWTR = 11, tRDWR = 8, tWRWR = 6, tRDRD = 6, tRTP = 3, tRRD = 3, tALL_PRE_REF/ACT = 6
CK Drive = 3, DQ Drive = 8, DLL Ch1/Ch2 = 5, Cross clocking CH1/CH2 = Aggressive, Commonclock = Aggresive, Enhance Data = Fast, Enhance Addr = Fast, T2 = Enabled

Only diff with these and your munchkins is these PSC are low voltage ICs.

Update: Wow after staring at register dumps over and over the past few weeks I figured out where CK Drive and DQ Drive strengths are stored in MCHBAR register offsets!

CH1 Clock Drive Strength = Offset 33Dh, Dimm1 Clock Drive = 33Dh[3:0], Dimm2 Clock Drive = 33Dh[7:4]

Clock Drive = 3,
FED14330 00000000 00CC0000 02000000 00003300

CH1 DQ (data) Drive Strength = Offset 419h, Dimm 1 DQ Drive = 419h[3:0], Dimm2 DQ Drive = 419h[7:4]

DQ Drive = 8,
FED14410 02200000 02000000 00008800 40008000

DQ Drive = 6,
FED14410 01980000 02000000 00006600 40008000

DQ Drive = 8,

DQ Drive = 6,

And thats pretty awesome find I think, been pondering it for a while and noticed it out of the blue while testing my memory skews and stuff.

[johnysb]

Firstly, thank you a lot for your answers.
Been messing up with rams the last two hours and finally i believe that rams stop at 1093Mhz.
Whatever i do they wont go any further.
Will try them tomorrow again and see!
Thanx again.

[DiscoTech]

DFI DK X48-T2RSB Plus or
DFI LT X48-T2R or some other board?

I have 2 4870 512MBs to crossfire that is why I was considering the X48, also have 4x1GB CellShock D9GKX.

I need the highest overall performance for gaming. (so I do not care if I can overclock my ram better if my cpu overclock will suffer)

Thank you

[Inquitus]

I have a UT X48 TR2, great board, worked great for me for ages. Decided to take the jump to Vista 64 and at the same time go from 4GB to 8GB of RAM. I bought 2 additional 2GB Sticks of the same RAM.

1st time I try to boot with 4 sticks it stops at C1 on the post, flashed to latest BIOS, it boots but plenty of Memory instability becomes apparent. Run Memtest as soon as it gets to the 3rd dimm 4-6Gb it stalls. Run a windows memory checking tool, same again. Did some mucking around and its not a dodgy stick, whatever is in dimms 2 and 4 gives errors, all sticks pass memtest when just 4GB installed.

Memory is PC6400 running at 400FSB and timings are set by spd, tried varying the voltage from 1.8 to 2.1, makes no diff, tried upping the NB to 1.3V, again no improvement.

Any ideas?

Thanks,

Inq

its verry possible 2-4 are deffective cause i can run 1250mhz with 4 stix
btw you gonna need 1.45-1.6v on nb to run 4 stix


Shiranui Gen-An use 333/800 divider 1,6-1.65v nb
my board on vacation in a nice box

Is that much vMCH safe for 24/7 use? As for my X48, it has replaced the P35 in my main box as for whatever reason it gets along better with my PCI IDE cards and so far seems a lot more stable at the 500x8 333/800 settings.

thats nb voltage
and ya i think its safe as long as you keep her cool
my nb never went above 40c even with 1,65v
if you wanna keep it safe you can run stock
and you got a ut it should be a better chip that my x38

[Shiranui Gen-An]

Still can't get it stable with Aggressive/More Aggressive, I wonder if having lots of peripherals and drives running DMA mode has a bearing on this.
