try harder cause the only thing i couldnt do on this board is go past 555fsbQuote:

did you try 140-130-110 range

I tried everything guys.. 150 to 90, no go. It worked with 1,4V VTT and GTL ref to 68/67% on the IX38 all the way to FSB 480. And I know you can hit 500+ easily on a dual, I was priming my E6600 on a P965 at >500 years ago on a 1066 strap like everyone else, no big deal.
But it really seems the X38 doesn't like my Quad. Hell, I've seen people go back to the P35 because they said it clocks better...
I feel your pain, but look at the bright side - I just realized that the X38 chipset delivers a better data throughput for the quad-core in multi-threaded apps than the P35, clock for clock. This is not easily seen with most single-threaded benches out there, as X38 bears little difference from it's outstanding brethren P35. In single or dual-threaded apps both chipsets trade blows, but X38 stands out where you want to fully realize your quad-core advantage. It's a better multi-tasker chipset I'd say. And that's why we invested in a quad-core, isn't it? ;)Quote:

i got both the ut p35 and the x38Quote:

dfi has to get off their buts and start making a bios as good as the p35
i dont care if i cant get past 555fsb i'll be happy if the x38 is as fast clock per clock
Ok, so I just got my E8400 a few days ago and I should have my DFI LT X38 in a few weeks. I'm planning to do at least some OC'ing with the board (Not much, as it will be air cooled), but I don't quite understand a few things. Hoping someone can explain it to me.
I notice that some people seem to be lowering the multipliers on their procs. What benefits are there to lowering the multipliers as well as raising the fsb when overclocking?
Thanks in advance!
if u lower the multi then u can raise the FSB higher than the fsb could run with the higher multi in most cases, this allows for a higher NB clock so the ram can run more efficiently
Something about this board is bugging me, and I need some help. I have a setting for my Q6600 at 3.2GHz for low-power job, and that setting has been blessed by both Prime95 v25.6 small-FFT (15.5 hours) and Blend (12 hours). Still, I am suffering random system restarts from time to time, out of no reason at all. The BIOS version is 0314, which is also the same BIOS those rigorous long tests passed with.
Every time this happens I checked Windows Event Log and there's nothing wrong reported. It shows as if I restarted the system, while in fact the PC tripped itself. I even had the temperature warning disabled in the BIOS and that still doesn't stop this problem (so apparently it's not heat related). BTW during those Prime95 tests none of the core temps went beyond 57C at 3.2GHz.
I suspect I got a bad board, but if it is bad why it was so solid during those long burn-in sessions (I have Everest event logs back that up: all volts are nearly unmoved). The PC is plugged in to a 750VA UPS as well. What could be wrong when all the tests results are perfect? I need troubleshooting ideas... :confused:

Did anyone have problems with boot using certain Vcore ??
I've changed CPU (E8500>E8400) and strange thing - I can set Vcore to max 1,22500V - anything higher causes "no boot" situation :shrug:
I've tried all settings up to 1,35000V, and 1,40000 and 1,45000V - no change, still "no boot"... :shocked:
CPU works great, (480x8@1,2V Orthos Stable, 480x9 SuperPi @1,225V SuperPi stable but needs more Vcore to be Orthos stable) - but it "no boots" :stick:
I've tried latest beta (2008/06/03) and latest official (2008/03/14) bioses and unwillingly want to change to previous versions...
Funny thing, the problem does not occur on my previous E8500 and backup CPU (Celeron D420)... :shrug:
I heard people have this problem on DFI LP P35 - and cope with problem by using old (too old) bios... Actually DFI X38 has only few bioses - not much to choose and it's not good to loose its' fixes... :down:
Anyone has any suggestions ?? :help::help::help::help:
1)dont use the betaQuote:

i wonder if the will have the same issue with teh 4870x2 as it does with the 3870x2?
1) tried latest beta & latest official - no difference... older bioses still to come :confused:Quote:

Asus board - no, thanks.... not yet :cool:
personnally ive tried every bios x38-x48-utx48Quote:

At 3.2 (400x8) I have the GTL tweaking disabled, don't think it needs that at this slow speed but I'm gonna give it try later and see if that improves. The P95-passing vNB is a mere 1.278v and I've started to increase one notch after each random reboot. So far it's at 1.356v and I still see random reboot. Don't think I need to overvolt it at 1.5 as this doesn't seem to be the right route.Quote:

I noticed on DFI's website that the latest BIOS for the UT version is very recent whereas the LT has one back in March of this year. Now can I flash an LT board with the UT BIOS? Just curious, that's all.
Thanks!
EDIT: Ah crap, I posted this in the x38 board thread! Lol, the x48 one was right next to it at the time when I clicked the link. Sorry about that. :embarrassed:
well the 1/11 best so far for me no c1 nightmare headachesQuote:

i'm tellin ya you gotta find the right gtl settings takes time but its fun lol
Thanks, will definitely give 01/11 bios a try, coz 03/14 does give me some C1 error occasionally. :down:Quote:

My problem is hmmmmm. solved... half way :)Quote:

After all CPU works great with initial bios release (2007/11/28) and all Vcore voltages are accesable...
480x9=4320 @1,3700 (bios) and RAM @1152/5-5-5-15/2,0V (bios) - no timing and voltages optimisation yet...

Will try further bios versions - but DFI should be more creative&sensitive to users issues/problems... Come on - only 6 bioses (3 official & 3 betas) after over 6 months of this product on the market is a little dissapointment for me... I would really like to use latest bios without being forced to use initial release just to have fundamental option as Vcore adjustment operational...
Ups, time to update my sig :welcome:
i can set to auto all the way to 500fsb n boot but is it really stable noQuote:

Keep in mind that the bios vNB setting is undervolting.. so if you give 1,5V it's more like 1,45V really.Quote:

Hmm... could that be driver issue instead (or conflicting drivers even though it doesn't show in device manager)?Quote:

Also what is the best reference while tweaking the GTL, do you guys all look at this table? That's for UT P35 board and I wonder if anyone has an update for LT X38/X48...
Good sources - Thanks Dimek! :D
