how do they work with no cooling at all?

Just a fan on them

[Jor3lBR]

How I fixed: I placed 5 1in binder on them then let a overnight Memtest #5 on tight timmings and high speed.

Now with the tape re-glued by the heat I only need 2 binders on each module and it will fit the 4 sticks without touching each other.

All with active cooling (OCZ XTC).

Fixed:

Sorry to be a pain, but I was hoping someone could answer my question regarding a vCore limit to the 45nm Quads ... in my case the Xeon 3360 ...

I am slowly working into this board and proc with 4GB OCZ Reaper PC2 8500. I can't quite seem to get a decent range of voltages that will let me go above 445FSB with either the 8 or 8.5 multi ... any suggestions? At 440 FSB with the 8.5 multi, and vCore around 1.36v she'll boot into Windows (XP 64) without a hitch, but as soon as I try to run Prime95, the first two cores halt immediately , yet the second two keep on working ... really weird shyt! I can bring it back down to stock volts and not a single problem with all four cores ...

Those Prime95 issues can be due to wrong GTL settings or disabled.

Did you try to tweak GTL'S acording to Cluncks chart?

It's not always vcore that your processor is asking for.

[AKHandyman]

I have been working with them today ... I started all over from scratch and now I am in a Prime run with settings as follows: vCore-1.26v(real 1.24v); CPU VTT-1.1v(same); NB-1.462v(real 1.45v); DRAM-2.19v(real 2.16v); 8.5 multi x 400 FSB, DRAM Target speed is 333/800, GTL is disabled for the time being ...

I have had it up higher and did some preliminary benching with SuperPi but what is the fault when the error says "NOT IN ROUND" or "NOT IN CONVERGENCE" or something to that effect? Do I need more or less of whatever?

That's right, we had quite a few spreaders that came off at one edge - more pics here.

The last set of Tracers I got were D9 and had the old style heat spreaders on, and they too were already peeling off, so I removed them entirely and they have been my longest serving set of D9 RAM ever.

This was the Brand new set of tracers before I de-spreadered them.

thanks, now im really worried lol
i checked them they dont look like there pealing yet. and they seemed stable with all 4 at 1140mhz . but then today i got the c1 error and it wouldnt boot , i restarted and it boot ok. so im getting worried. and im too scared to run a memtest on them incase i get bad results. lol

[Bitgod]

Silly question, are the green and yellow board connectors UV reactive?

If X48 is like X38, then memory clocks maybe sensitive to clock fine delay values once oc'd - might want to fine tune the values for your memory http://i4memory.com/showthread.php?t=4743 which can product very dramatic gains in some cases!

thanks eva thats awsome info there. ill read through it soon and get into changing some of those fine tune settings. i did notice fine tune in bios before but wasnt sure what i should set them to.
thanks again.

Greetings all,

Can't seem to get my X48, Q6600, or G.Skill PC28000 2gbx2 stable at anything past 3.6 on 333/800, or anything reasonable on 333/677. I know the chip can boot into windows at 4.2, and the memory clocks to around 1030. Would I use 333/667? When I do get anything remotely stable, I have corruption on downloads and random crashes in small applications (Firefox, pidgin), but they can OCCT for 30 min+.


Here are my current settings I'm using to achieve 3.6 barely stable.

Any help appreciated, as I have a sweet WC setup and want to hit 4

edit: I also have tinkered a bit with gtls, and maybe that was one of the reasons I hit 4.2 and posted one time. Any recommendations for 4.0-4.2ghz gtls and corresponding vtt?

double edit: I am no longer even stable at 3.6 for long periods, ater a while I get app crashes then bsod.

[Rinaun]

Silly question, are the green and yellow board connectors UV reactive?

I just checked im my blue led case, and I didn't see much glow off of the sata plugins. Everything else lights up I think.

[Monkey101]

I just got all my new parts up and running but i keep getting random system freezes while playing games (Pro Street, Supreme Commander).

Running XP 32, 8.2 Catalyst. Rest is in signature. Not to sure if its related to voltage settings in the bios. Even with everything at the defaults in the Bios it still freezes.

Any help would be great.

[wilson]

Have you run 3dmark 06 yet ??

[Monkey101]

Yeah i did. Multiple times. Supposedly there is a compatibility issue with DFI X38 and 3870X2. Guess the problem was brought accross to the X48. Anyone know of a sure fire fix for this?

eva, ive been reading through that link,( since i just discovered im not occt stable).
my question is wouldnt setting fine delay to relaxed have the same effect? or am i better of reducing memory speed abit then reseting fine delay to match stable settings?

edit* relaxed settings didnt do anything, so forget that q's . still unstable with occt. im trying what u said and i reduced my memory speed. but i had to reduce fsb to reduce memory speed. how can i reduce memory speed only? it doesnt seem to have a separate setting for reducing memory speed? i overclocked using strap settings and increasing fsb i didnt increase memory manually.
also is occt to strict? seems stable with prime but looses out with occt.

[Bitgod]

For OCing and WCing, is it ok to stick with the stock SB heatsink? I'd expect so, since if I recall what I read somewhere, 2 of the things the SB is responsible for is the JMicron and the on-board sound, neither of which I'll be using I expect, plus that high intake fan on the TJ09 will probably put air right on it. I'm just in planning to order parts mode and wanted to see if I needed to snag something like an Enzotech SLF-1.

SB heatsink works well, doesn't really get very hot.

Can't hurt to give it a repaste though

[adya]

i reduced my fsb/memory to 450/1080 ive been running occt for 1 1/2 hours seems stable , so ill go into bios when its finished and note down fine delay settings. then increase fsb/memory back to 475/1140 with stable fine delay setting on manual.
edit* ok i did it , but the stable "current" settings wont match the manual settings? sometimes by more than 50. i had to use the closest figure. any way of setting it to the exact figure?

[adya]

damn i cant get it stable at 475/1141 . becuase i cant set fine delay to the exact stable settings.
is it better to just keep lowering it till its stable? lower= stable? its a shame this bios wont allow me to set it manually properly.

[Jultsu]

I just ran prime95 for 11 hours straight with my q6600,

9x420 = 3780MHz
strap 400/800
vcore 1.392v
VTT 1,312v
NB 1.504v

And now I installed another 4 gigs of ram, let's see how high I can go with 8gb Now benching 9x425

mines prime stable for 5 hours but fails with occt. i think occt is either way to strict with its testing or prime is weak. has to be one or the other.
did u test with occt at all?

[zsamz_]

damn lol i dont test prime more than 1 hour no more
puts too much stress on components for my taste

9 hours i bet you stable

[Jultsu]

Nope, I use just prime.

425fsb gives a BSOD within 30 minutes. If the CPU isn't getting enough juice, shouldn't the prime worker threads just halt to an error? So, is this a memory/NB -related issue?

test with memtest to see if its memory related
try 1.45cpu n 1.4 cpuvtt try setting correct glt settings

@zsamz_ - How did you put the X48 BIOS on your DFI X38 board?
