ski, whats your q6600 VID? This is so important!

My VID is 1.25v, and my batch is L744B127.

And whats happening with your PC on the moment you get the error? I've noticed some patterns here and there.

I can boot into windows fine and work (surf, email, etc.), but when I load up Prime95 it locks up in about 4-5 minutes. Screen is frozen, no BSOD or anything. I have to hit the reset to get out of it.

SB and NB hate MX-2 thermal paste, they need AS5. Always be carefully with those mounts (especially NB), they never fit properly (heat in some poor contact area can make your OC bsod or reboot).

I'm using the stock paste on the SB, as well as the Shin Etsu stuff that came with the board for the NB. The Shin Etsu was pretty thick, but I placed a good-sized ball in the middle of the IHS and mashed it down with the stock heatsink & twisted before I secured the pins. According to Smart Guardian, the highest I've seen the NB get under load was still under 40C.

But will the x48 ddr2 be a disguised x38? Wait and see...

The pic on the MBPro site looks different that the X38. The third PCIe 16x slot is not at the bottom, a PCIe 1x slot at the top, and all 16x slots were two slots apart.

Ill have a answer in a week in half,if things go smooth.

Nothing special in my room and case temps I think:
Room: 75oF
Case: 83-86oF
Water temp I can't answer because I don't have a reader there (but it's not chilled or anything to cool it down, is a normal Asetek kit with only the cpu loop).

i see.. interesting about MX-2 vs AS5 comment. i used MX-2 on my DFI X38 LT R.A03 board for PWM and NB/SB heatsinks

MX-2 needs pressure from at least 4 mounting points to get a smooth even contact (I mounted and unmounted uncountable times nb, sb and cpu hs's from different boards and noticed that with 2 points only there's not enough pressure for MX-2 to make perfect contact).

I observed little blind spots like "islands" and "waves" on the surface of the SB and NB that aren't present on the CPU.

My theory is that if those little spots without a good contact can heat up so fast that can BSOD during Prime etc without the sensors even catching it on time. That's why a perfectly cool system like t_sky's can suffer from those symptoms (not that this his case).

[eva2000]

Interesting, might do a reapplication on NB/SB and see if it helps my max FSB heh

[SNiiPE_DoGG]

all I know about nb is that I hard mounted my NB air cooler (good pressure) and couldn't get stable 4ghz even with high speed fan.... now that I switched to mcw30 nb water cooling 4ghz stable 24/7 for 3+ weeks

What about something thicker like the Shin Etsu or some Noctua NT-H1?

[Villainstone]

Well I can't seem to get 500 stable or even boot to windows for that matter. I can go into the BIOS NP but windows seems impossible. I am to to keen about upping my voltage because I am not sure how high I can go. I am hoping I can get a bit of help here but I am going to bed for now. Thanks guys have a good night.

you gotta update your sig
n set proper gtl settings
readin some of this thread will help alot

the nb springs are way too soft first thing i did was change the springs on nb
even with 1.72v @ 555fsb my temps didnt hit 45c on load

[jimmyz]

Thats probably the reason Mobopro's said a month or two ago that DFI LP x38 is dead, not coming for stock anymore. They know more about DFI then DFI employee's

But will the x48 ddr2 be a disguised x38? Wait and see...

odd you should mention that , I had an x-38 I got in early january and cpu-z showed it as having an x-48 chipset, it ran a few hours while I set-up the rig and when I rebooted and went to flash the bios it rejected the bios and refused to boot after that, I rma'd it and the replacement (on the same windows install) showed up as a x-38? maybe somebody screwed up? It doesn't make much sense I know, but the first board acted very very screwy and refused a flash (also refused to boot with a fresh bios chip from Brother Esau).

[mArCo1928]

marco if your ballistix has d9gkx chips you better off cas 4
all my ballistix with d9gmh can do 1200+ with 2.1v
my mushkins cant do 960 5-5-5-15 with 2.3v but i can do 4-5-4-12 1050mhz with 2.22v 2.27v set in bios
i can do 1100mhz 4-4-4-12 with 2.3v but cant do 5-5-5-15

use 333/667 or 333/800

jor3lbr i got spare bios chips so i can try that x48 bios lol

how can i check if my crucial have d9ghm or d9gkx? on the maximus formula i can do 675MHz CL5 for super pi 1M with 2.2V. high frequency and low voltage=d9ghm? i don't know

Odd also.Had a ut p35 t2r that reported DDR3 ram timings in bios .

[mArCo1928]

ok, i think that one of 2 my banks is broken... the secondo bank in third slot (green) work great at any divisor, the other bank sux and fail orthos after a few second... but at 800MHz all of 2 banks work great, is possible?

[triple]

Hi guys, I got a problemo.

Heres my specs, first off.

e6750
2gb corsair pc6400(2x1)
4gb gskill pc6400 (2x2)
2x 3870s
two seagate 320gb
one seagate 500gb (all sata)

now.. when I bootup.. itl boot up. itl even install windows.

when I try to change anything in the bios though (say, changing the hd priority) - it'l stop after detecting the cpu speed during post and give me postcode 50.

If I clear cmos it boots again. Whats up?

[flexy]

Check this out:


So flexy, are you stable now at 3.6GHz? Would you be able to post your BIOS settigns for me? I'm still having trouble getting there myself...

t_ski, 3600 a NO GO, no matter where and what voltage i increase.

3555 is absolute upper limit, i OOCT yesterday for 40mins at 3555. Any higher ---> BSOD.

I run 1.41 VCore, 1.38 VTT, Dram at 2.2 5-5-6-18 (OCZ XTC plats "value" ram) 2.2V

Run 333/800 8x442, mem at 530 but TRCD at 6, perf lvl 8.

5-6-6-5-18
4-48-8-14-11-3-8-3-4-3120-2t (as in memset)

[Origin_Unknown]

anyone using an e8500 that would like to share there BIOS template for 4ghz?

use 333/667 or 333/800 dividers

test them with 2.22v-2.3v @ cas 4
unless you really wanna void warranty
n go 1.5v+ on nb

Hi All! I've switched from the Abit to the T2R and I'm having an issue with my Areca 1220. Not OC'ing yet, the system freezes for a few seconds at a time and will not access anything on the Areca card using Vista x64. I've tried the card in the second and third 16x PCIe slots and used both the storport and scsiport drivers with no change. The problem doesn't occur at all when using the IX38. I also do not have a problem on the T2R when using Server 2003 x64.

Anyone else having similar issues with Vista or anything to try in the BIOS?

[Villainstone]

What do you suppose my Gtl setting should be set at? I am scanning this thread right not but I see you already 555fsb. I have no need for 555, not to mention my CPU wall is about 3.7. Can you please elaborate about the GTL I would really appreciate that.

there has been people mentioning the same thing with Areca. try the DFI forums and of course google. sorry I don't know how to fix it but at least you now know it isn't just your rig.

try putin it on first slot n v card on second slot

if you looked at the thread its been posted a few times
i guess must be hard to search
read the thread a bit before you ask questions

first one for cpu second for nb + add 1gtl if you not stable i prefer 68-69%

you can always get lucky n try auto lol
