nicxus has them in stock but at just over 260$..
my old A8V did that with my samsung ecc when i took them to high, so i would expect that thats the same thing
does the lt-x38 "officially support" ddr2 1200?? or only ddr2-800 on the dfi web site is says 800.. i know it can be oc'ed past there but is it "officially supported: other companies say they officially support it.. just curious someone i know asked me this since they are interested in this mobo
i think that its only official to 1066 since there are 1066 multis
There is no DDR2-1200 from JEDEC... so I'd think no one really supports more than 1066 officially. Might be wrong though, but who cares about official support anyways ^^
These settings are wPrime 1024M stable, but nowhere near stable enough for Prime95. I don't mind loosing some speed to gain stability, but nothing seems to be working yet. Remember, I am running 4 Dimms (8GB) or ram with this, and I really don't want to go back to 2. Also, I am getting some about 62* C on 2 cores when wPriming. Should I reseat the water block? That does seem a little high to me.

Well I'm no superstar & I don't even have this x38 board but I hate too see people struggling.
The few things I would do would be firstly fling out 4gb of RAM & leave the RAM 1:1 until you have an Orthos/Prime stable rig assuming you want Orthos/Prime stable rig.
You may want to try playing with the GTL's around 100 or so based on your 1.503v vtt x 0.67 = 100.
You may also try setting the GTL+ Buffer strength to weak with or without GTL's enabled (works for some)
Return the PCI-E clock to 100 (no need to tweak that until you are stable)
I may be off base a touch here but don't those G.Skills have a max of 2.1v & have over voltage protection onboard. I think they don't like over volting ask Praz he's your man for these sticks.
NB voltage may need to come up a bit imo (worth a shot)
I would also based on what I have heard (not experience) manually set trfc out to maybe 50~55 till you get stable. I hear/see they like it loose & I would bet the board is setting 30~40 maybe.
62oC looks ok for 1.5v @ 3.7GHz imo
Hope some of this helps (ain't gona hurt to try)
CN :)
C-N has some good recommendations...these are mine from what i remember when i had the board set up with a Q6600 and QX9650...these are by no means absolute settings...experiment from there (recommended settings in red next to your settings).
i wouldn't get wrapped around the axle with Prime95 for more than an hour...having Prime95 stable system is not an absolute guaranrtee that you are completely 100% stable in every condition.
There is no way in hell I'd recommend 1.8-2.0v PLL. Sure way to kill something.
I am beginning to suspect my ram. I cant get it to pass memtest at 1000mhz anymore. Could my motherboard be overvolting the ram or is this g.skill stuff just :banana::banana::banana::banana:?
I cant get it running at stock CPU clocks with these speeds. I am getting Hardlocks in memtest. Is there anything motherboard related that could be fueling this? I am starting to get a little depressed over this.
I mentioned earlier that my board had what looked like cosmetic damage near some of the northbridge traces. If they were actually damaged, that would = no boot, not memory and stability issues, correct? I don't know, I am just trying to get this figured out in my head.
I haven't been using all 4 sticks since my instability issues in orthos because I figured that would remove some of the extra variables.
I will give you the 266x9 results shortly.
I am going to order some faster, 1gb ram modules and see if they help. If not, they will still be fun for benching later on. Please, if you have any ideas about what is wrong, let me know ASAP.
I said they'd kill them, you said they'd degrade them. Whatever. I think you proved my point anyway. But, I guess if they have a bunch of cpu's to lose to degradation like you, then by all means, they can throw as much voltage as they want into them. I don't recommend it though. :P
BTW, the 1.5 is absolute max.
Ah, the DFI spokesman has arrived!!!! :P
my bad. i mixed it up with fsb_vtt for the 88% bit.
your chart is strictly for stock speed...intel doesn't support overclocking.
guys...what i recommended for SB was what i needed to support my overclock..you can do what you want...if you run your board 24/7 then stay at a lower overclock and therefore, a lower SB voltage....fairly simple.
just remember your in an extreme forum...i stress extreme!;)
I agree, to some extent that we are in an xtreme forum, however, I don't agree on giving people searching for help, advice that can wreck there cpu in quick fashion. Unless a disclaimer is given. lol
this is an extreme forum and maybe you need to go to a softer forum...LOL
AND..since when do they have to follow my recommendation...i put it out there...you need to climb down from that tree.;)
nice attitude. it's also a helping forum. anyway....................................
Guys let's chill. No one here is naive to the point of "jumping the cliff" only because someone tells them to.
When you ask in a hardcore forum for opinions ppl will give the ones that suits them best and usually that worked for them.
That doesn't mean it has to be taken as absolute. You take little data from one and collect a little more from the other and that's it.
The best way to tune-up your system is to use common sense and use these opinions with caution.
divider problems:
i have problems changing divider in my bios, right now i am running 9x393 at div 266/667. This is the only divider which works - no matter what other divider i set i cant even boot! Even if i keep CPU at the same speed and even if i clock ram lower than what i have right now.
i just dont understant this! It just hangs at boot. With same settings, just divider changed, CPU/Ram the same or lower.
Sweet, I cant get it to boot into windows now, at stock clocks. This blows!
I am assuming that errors in orthos could be caused by bad ram just as easily as a bad overclock, right?
3 of the 4 sticks I have are not working. So, I took a known working pair from a computer here (passed memtest) at work and put them in mine. Now, it will not boot and freezes anytime I try to load windows or even the installation disk. This is with the processor at stock speeds and voltages. Ideas?
using 4x2GB Gskill PC2-8000 2GBPQs ? test each one individually with tRFC manually set at say 52, 56 or 64 first and see
stick with 1:1, 5:6 or 2:3 dividers to test memory. Latest bios fixes 5:8 divider but 4:5 is still limited to 440FSB and 3:5 is a no go. Prior bioses may have no boot if you try using 5:8 divider even at 266FSB!
I cleared all the settings in the bios and loaded optimized defaults. Now, it runs fine. but yea, eva2000, I did exactly what you just described and only 1 stick passed at 800mhz. I am more than a little upset with G.Skill right now. I REALLY want my money back, but I doubt I will get it.
Looks like the manufacturers are doing good job there since DDR3 is out, it says to me that they really work on it so we jump up to DDR3 from DDR2. Since I don't know what to tell about it, more and more ppl are getting problems :(
GL Razor :)
this might also work for OCZ XTC Plats 2, assuming they are powerchips. (Its the same as reaperx, they sell them in Europe without the reaperx ramsink as "ocz xtc platinum 2")
A related question: Is it generally better to run ram 1:1 with FSB???? i read this once in a while. Then others say its better to run FSB and ram higher.
sorry to bring this up but does this board favor the D9GMH based ram better or the D9GKX? just wondering cuz im thinking about picking up some cellshocks. thx
thx praz, just wondering cuz my tracers dont seem to clock very well. cant get them stable at 500mhz 5-5-5-15 at 2.2v.
could anyone recommend me some good ram for this board?
i would get some ballistix 8500 but the seemed to have changed the chips on them.:(
edit:
should i try a different bios im on the 11/28. thx
praz is right i got a pair of mushkins with d9gkx needs too much voltage for this board but i can do 4-4-4-12 @ 1120mhz 2.3v and cant get cas 5 stable even with 2.3v past 1000mhz
my ram is warrantied for 2.35v but i prefer to use less volts after 3 dead kits
my ballistix are now @ 1200mhz with only 2.1v
So, I just got in my new sticks of ram, and none of them work either. I am beginning to suspect the motherboard. I have set everything to loose and tried many times. but no go. So, what is vote: CPU or Motherboard?
don't think it's just D9GKX that acts that way (maybe not as bad CAS5 but similar CAS4) it's just the binning process at the time.. lots of D9GMH produced around 12-18 months ago behaved the same with same cas4/5 scaling at similar voltages until better binned D9xxx came along
The D9GKX sticks I have will do 4-4-4/1200MHz+ on the 975, 965 and RD600 chipsets at 2.2V or less. I've yet to find a board based on the 35/38 chipset that these sticks will do the same without having to use 2.4V+ on the memory and a massive amount of NB voltage.
Anyone? CPU or motherboard? There is now way that I have this many bad sticks.
Could it be memtest? I am using the new version of it (2.00).
2.0 is a bit glitchy i prefer 1.7
Well, it looks like DFI is going to do a cross ship. I hope this does well, or I will be buying an Asus Rampage Formula instead.
Anyone knows what errors in Memtest #7 means in this board (too much volt for mems, too less, to much Vnb too less?)? :shrug:
I'm getting them with +/-1200Mhz + 4x1gb Tracer's 8500, what should I do?
@zsamz_
yeah i got mine a while ago too. i guess bad luck as you said.
anyways been looking at the cell shocks as they are guaranteed D9GMH. What do you guys think i could get out of these on this board? or recommend something else better or cheaper?
thx.
play with combinations of NB volts, vdimm and clock fine delay values
not sure as i not 100% sure if i have any D9GKX in my collection of Micron D9xxx - see list below. But for benching I've used between 2.45-2.65v vdimm with no probs on my list below.
Guess i haven't been as lucky only 3 or 4 sets of my memory can do 600mhz 4-4-4-x and they all need 2.55-2.65v to do it.
- 2x1GB Super Talent 8000C5 Singles
- 2x1GB Team 6400C3 Micron D9GMH
- 2x1GB Corsair 10000C5D Dominator
- 2x1GB OCZ PC2-8000 Titanium Alpha VX2
- 2x1GB OCZ PC2-9200 FlexXLC
- 3x 2GB Crucial Ballistix Tracer PC2-8500
- 8x 2GB Crucial Ballistix PC2-8500
- 2x1GB G.Skill 6400 2GB HZ
All above are Micron D9xxx based but heatspreaders intact so can't confirm them with exception of 1 set of Crucial Ballistix Tracer PC2-8500 i lifted heatspreaders from due to mis-aligned heatspreader and they along with already naked pair of Team 6400C3 are both Micron D9GMH.
Wow thanks a bunch you guys:)
@eva2000
I wonder if i should take the heatspreaders off my tracers because when i took them out one time and noticed a sticky sound from the TIM not making good contact with the chips themselves. since then i have a fan directly on them.
i guess ill take my chances with the regular ballistix 8500 because they are so cheap these days.
anyone know if there is any real difference between china vs taiwan made boards in the lt-x38.. on some boards it seems most people say the issues they have are on a china made mobo..i dont hear many issues with taiwan ones or at least no one has said they were taiwan ones?? just curious if there is/was any quality difference between the two?? thanks
I suspect some of the reported crucial ballistix module deaths have been due to such poor contact between heatspreader and ICs... as such if the heatspreader wasn't making contact, I'd remove them (very carefully with help of hair dryer). Risk is rma'ing them you could get the poorer clocking single sided ballistix modules as replacement :eek:
yeah I can imagine!... strangely though most of my ballistix modules can do 640-650mhz 5-4-4-x at similar voltages needed to do 600mhz 4-4-4-x !
he is probably talking about the vCore issue (some component had different specs than taiwan boards and thus the bios/vcore table was not corrent, resulting in wrong real vcore voltages as opposed to set in bios). The last bios fixed this.
have china board and cant complain. 3537Mhz Q6600 on Air OOCT stable....waiting for better fans in mail to attempt higher vcore and OC.
i dont trust Ram HS at all!! They come all off sooner or later. An idea would be either a) to remove them and screw warranty or b) use something like those strong foldback clips in addition to hold them in place.
http://www.euroffice.co.uk/_image/it...e/250745_0.jpg
clip them at the side so HS wont come off that easily.
I remember it was NB voltage that was much higher than set in the bios for some settings and yes that was fixed with the last bios.
Yeah i used those clips + hair dryer to get another set of ballistix tracer's heatspreaders to make contact with the ICs and it worked!
clips you just slip off, i worked on one side of heatspreader at a time, heating the heatspreader up and then using a plastic credit card like cut out and my finger nails (mainly thumb) and started on the edges slowly lifting heatspreader and you can see the thermal pad slightly lift off if you're lucky, use plastic credit card like cut out to cut into the thermal pad further in, then re-heat and do it again until thermal pad on each ic becomes more loose.. re-heat as needed.
You'll get to a point where the whole one side heatspreader is pretty loose, then bit more prying pressure will get it off.. NEVER force it and take your time. Then do same for other side.
I had a board from both and they both died within 2 weeks. So for me it didn't matter where they came from ;)
I'm back on a spare P965-S I had stashed in the closet from when I was trying to determine whether low batch numbers overclocked better than later ones. Unfortunately this board is not the better of the 2 I had (the first one ended up in DFI RMA nightmare hell), but the overclock with my Q6600 is the same on this board as what I could get out of the X38. So outside of my Crossfire being slower on this board, everything else is the same.
I know my quad can go higher, but neither the P965-S (not surprising) nor the LT X38 (very surprising and disappointing) can take it there. Eagerly waiting for the Rampage.
some ballistix early on had D9GKX
From the 'DDR2 RAM List' they can have GMH, GCT and GKX. Haven't seen the D9GCT's on the Ballistix 8500 before :shrug:
thanks for that list!:up:
Yeah it can be useful, but don't rely on it too heavily... that list is ancient really and rather outdated in most cases (small wonder considering all those different manufacturers, models and ICs out there)
everything on auto +more aggressive
nb 1.6v vdim 2.13v gtl values enabled 68-69%
i only run 2 stix now since i dont need 4 gigs and it puts stress on the board
but the board ran 4 gigs like it was nothing
i couldnt do 800mhz on x38-dq6
with 2 stix i'm @ 2.09v for 1200mhz 24/7
I'm getting my board end of this february. pairing with q6600 and reaperx.
What Air cooler will fit on the motherboard? Will I be able to install the northbridge cooler with Thermalright ultra 120 ex?
LOL..."blowing up", like boom!:D
yeah saw lot's of setup like the way u mention.
Will it effect the case flow? I'm using Lian Li PC-007.
Thinking either getting the 90i or True blowing up. Need to consider the other components as well, the PWM and also the reaperx ram.
get the true n dont look back the 90i not as good for a quad
you can always dremel the nb sink if you want it facing back
i got a laptop heatpipe heatsink commin for the pwm:D
then i gonna get an hr-05 sli for nb
i prefer it facing back for airflow but most saying they get better temps with it facing up
I have Scythe Infinity and it performs also very well blowing to the back
http://img132.imageshack.us/my.php?image=IMG_6036.jpg
nope. it can be down blowing to the side, towards the exhaust. i did it too. its a matter of 1/50 inch...but it works!
thermalright 120 ultra extreme. wait..i can make a photo.
http://www.gamerzzz.de/fans.jpg
User of DK P35-T2R also bend the fins of xigmatek 1283 to fit it blowing towards the exhaust.
Probably will get true then tried both setup, see which 1 gives the best overall performance. My country here hard to get HR-05, only can get SLI/IFX version.
Hello boy,
can you give me some helps in settings E8400 Q746A366 @445x9 with my Dfi X38? I've tried some settings options without finding stability in daily use. Only spi1m bench...
BTW a lot of times when I start some stressing utility like Orthos or Prime the monitor freezes for 2\3sec. and then the system restarts.
My sistems is in the signature
Hope someone of you will answer my question, i need seriously some support.
Sorry for my English, I'm writing from Italy
Bye!!
