Well i will start off with the problem i occured.

I had my p4c800e-deluxe and the ct-479 and my dothan 760 in house, so is started to play with it. First run was 28xx on stock voltage. Then i gave it more vcore and more vagp to achieve almost the 3ghz on air. Then a blue screen came and the system didnt boot anymore.

So i placed the pci vga card in a other pc and it worked. Placed mem in my Dfi nf4 and it booted. While on the dfi and in windows i saw i only had 256 of ram :slapass: so 1 stick died. Well ok its a problem, yes im angry but i did go further.

I placed the still working stick in de p4c800 and yes, he booted again. Went 2995mhz on air and another bluescreen. And yes, also this stick died

I didnt have any vmod on the board for the vddr, and everything was stock. Mem was running 2.85v and vagp on 1.7v ....................

User DaWan had the same with 1 bh6 stick..

WTF my xms3500 2x 281 2-2-2-5 stable sticks died because of???????????????? :slap:

Some one knows about this?

Had the same problem with my P4P800se.

Killed both my Mushkin Black lvl2 3500s and one of my KHX 3200 bh5s.

First died at 200MHz 2.85V 2-2-2 [I think - don't remember - May have died something higher but I remember having it at 200 and it still erroring, after a reboot no post]
Second died at 284MHz 3.6V - although was weird, clockgen would let me set anything (only tried up to 297MHz and CPUz showed 297MHz as well [though I find it hard to believe, used to freeze instantly above 284MHz - concluded it wasn't actually clocked at that] - error'd instantly in superpi though at that, even clocked down it error'd, rebooted and no post with no memory inserted beeps).
KHX died at 266MHz 2-2-2, 3.3V - same prob as the 2nd.

Yes it kills RAM, sorry for that. It seems that asus adapter + dothan + any Asus MB might do this

Here (http://www.xtremesystems.org/forums/showthread.php?t=83398) is my story on pci-e boards + dothan

If your system crashes try this to save RAM:
Immediately Power OFF, remove RAM, clear CMOS, Power ON, Power OFF again, reinstall RAM and power ON again.

Hope this helps

But how can the mem be killed if you dont have vmods or somethin like that. I mean then it is an engineering problem.... man ! :clap: well done asus.

i had a stick of bh5 die not long ago, i thought it was just me putting too much voltage through it (3.4v with 17c room temp + 2x80mm fans over). reading all the dead ram threads is making me wonder?

p.s sorry i posted in the other thread too (the empty one) didnt see this active one :)

Never had this problem(yet) with my P4C800-E and 2x256MB Corsair PC3500@3,5V(ocz booster),i had many crashes while finding the max oc of my M740.
I use the latest beta bios(1024.001) and sticks in dimm 1&3,no mods,turbo-2-2-2-5-4-infinite-7,8us-pat.
I use the sticks only to find the max oc and Pifast/Super Pi,for 24/7 i use 2x512Mb Twinmos UTT BH-5@200Mhz 2,55V(they only do 215Mhz max,2,85 or 3,3V doesn't matter so i still hope that Asus makes a bios that is optimized for Winbond UTT but that will be wishfull thinking:mad:).
Always 1:1 so no divider.

I just had this with a p4p800se i do have a vdimm mod but it was set to 2.8 in the bios and 2.8 on the mod from a meter.
i had my nice gskill tccd in slots 1 and 2 only running at 256 2.5-3-3-5 whic is nothing i was running at 278 2.5-3-3-5 happy before.
i pushed a pm780 to 3120 260x12 and the pc reset and wouldnt boot.
checked the ram and the ram close to the cpu died.
i did notice that once or twice the vdimm was showing 2.9 instead of 2.85.

This is worrying. full story about mine above.

2x xms3500 in slots 1 & 3 with a booster in slot 4

i managed to run super pi at 11x260 with 3.4v (1.55cpu) without error but the pc locked on shutdown. i restarted it and just got a blank screen, tried resetting cmos etc etc... but nothing. So i tested each stick in my shuttle one at a time and one stick just gave me 3 short beeps (dram error?).

12-21-2005, 06:26 AM

I've had tons of lockups, restarts, BSOD's while overclocking with my P4GD1 and Dothan 740 (not sufficient Vcore etc, used high Vdimm with Booster as well), nothing bad has happened so far for me. However, there is one thing I cannot recall whether I ever did those times: clockgen and cpu-z simultaneously. I think, I usually had one or the other open but never both of them.

We need somebody with an old crappy stick to test this theory (with clockgen and cpu-z open, and without), this has been told already before but nobody has answered the call with verified results yet. Saaya has duplicated the clockgen/cpu-z death story by killing multiple sticks but we aren't sure yet whether or not using these two programs simultaneously is the key to ram survival. What is already clear, is that this happens on all Asus boards while using the CT-479 adapter so both i915 as well as i875/i865 users should beware.

So basically people, if you report dead sticks, please specify whether you were using clockgen/cpu-z simultaneously when the sticks died.

One of my G.skill PC4400-LE with TCCD chips died on my Asus p4p800-SE. 2 weeks running on 290 5-3-3-2.5 2.65V with no problems.

Fuc*ing ASUS.

This board killed my 6800GT, 9500PRO and 6600GT. Every card died with another PSU(Etasis, Tagan easycon 480W, Tagan 2force 430W) and ran only one day. System was booting normal, but no signal there. It looked as no graphic card bios. I tried reflash 6800GT than 2hours was working, but when i restarted pc no signal there and i cannot reflash again.

Now i have Sapphire x800gt and everything is OK.

Sorry for my english.

12-21-2005, 09:32 AM

My P4C800 killed a stick of Mushkin Redline UTT XP3200 (3.4v with DDR booster). In denial, I did some research and read about a cold-boot problem with UTT that can make the RAM 'appear' to be dead. So as a last ditch effort I tried switching the slots on the mobo, and the stick literally fried with smoke. Two of the contacts on the memory burnt right off. I'm not sure if this was an installation error on my part, or the residual effect of the dead memory stick. Needless to say it doesn't work anymore.

12-21-2005, 09:44 AM

Forget about mailing asus customer support. They have the worst service ever and never reply :slapass: They even can't be reached by phone. The only option I guess is to go to their office. I hope their security guards won't kick you out :slap: :D

By the way, your stick might not be as dead as it looks! Here is the update of my kingston sticks.

They do NOT work on P4GPL-X + dothan. They don't work on i845E gigabyte mb. But they do work on gigabyte Kt266 board, memtest error free and prime stable. WTF?

Sorry, no more boards to test at the moment but this is strange.

If someone could try if this is the problem.... then this is something everyone should know if owning a asus+ct+dothan.

In the 2nd two sticks I'm certain that I had clockgen and cpuz open, the first I'm not sure but potentially did.

Not too many people I can image though, who'd kill a stick of bh5 for on experiment.

Maybe, might find someone with UTT who'd be willing to let one die...

Waus-mod

12-22-2005, 12:45 AM

Well its not only bh5 or utt. even tccd. So if someone has old terrible bad ram or so he could test it.

12-22-2005, 02:26 AM

Ok, checked all my old Dothan o/c screenies, I never see there Clockgen & cpu-z open simultaneously. In fact, if I remember correctly, I've always used the method by working with Clockgen up until the system crashes :D or, if it doesn't crash, then I close Clockgen and run the bench I wanted to. If the bench completes, only then I'd open cpu-z for screenshot taking/validation purposes. So this way, I've probably never seen Clockgen & cpu-z opened simultaneously... perhaps this has saved my precious UTT/BH-5 sticks so far? :shrug:

12-22-2005, 02:28 AM

kiwi

12-22-2005, 02:31 AM

Hmm, KT266? That's 133fsb and DDR266, right? I've had damaged BH-5 (also from Kingston but I don't think it matters here), which crash at their rated speeds and lower, but still run fine at low fsb (like that 133, for example).

But when I reset CMOS then default ram speed is 100 or 133 depending on the jumper position. Same is on i845 board, fsb is either 100 or 133. It simply won't work at all on these boards. Why does it work on KT266 is a mystery

Stigggeh

12-22-2005, 03:07 AM

Ok..... saaya was right.

Last thing i remember was the validation where i had clockgen and cpuz open for max suicide. i pushed the validation button on 3g and then came the bluescreen....

SO PLEASE PEOPLE..... stop using clockgen and cpuz at the same time

quess it was just a matter of time before toasted mine, i usually have both open :( when benching. surprised they lasted so long.

Waus-mod

12-22-2005, 03:18 AM

Ok so youre mem is also dead Stigggeh?

Johnny Bravo

12-22-2005, 03:35 AM

I'm confused. ALL my screenshots have both clockgen AND cpu-z running. I ony ran clockgen when increasing FSB after Saaya mentioned that runnig both meantt hat the FSB didnt actually rise but I have yet to see my ram die. I have had the system crash numerous times and rebooted but the RAM has survived. Is it just a case of luck of the draw?

audiojunk66

12-22-2005, 03:38 AM

Does anybody know why it sometimes takes so long when you start cpuz,i can't remember that it took so long with my XP-M.

P4C800-e DLX here with Dothan 750 at 2552 (212X12) with 4X512 old KHX 3200 BH5 running at 2,85Volts (2,5 in bios - using a +0,3 vdimm mod) and no problems so far. However I dont recall running clockgen and CPU-Z at the same time ...

I have lend my friend 4X512mb UTT in his P4P800 rig with Dothan 730 running at 200X12 = 2400. Vdimm is at 2,6. He has an P4C800-e DLX bios flashed in there and he can do restarts fine but if he powers off the system then it starts up whenever it feels like it :slapass: Lets say it starts again in 1 out of 5 power-on attempts :confused:

SO PLEASE PEOPLE..... stop using clockgen and cpuz at the same time

i cant comment on using the p4gd1, still waiting on the 780es there,
but my main rig, a 760 running on a p4p800-se (bios .003) with a pair
of khx3200/512 (bh5) has been running on it for about half a year now
at various stages of clocking madness. and for all i know i have ALWAYS
run clockgen (i865/875) and cpu-z at the same time. sometimes i would
start cg first then cpu-z other times i would do it the other way around.
i have had various lockups / resets on trying to find the max mem, max
cpu, whatever.. nothing ever happend.
the only thing where i *may* differ from most other people that have
killed one or more sticks is that mine ran in slot 2 and 4 from day 1. i
don't know why i did this, but i just did. and havent had a problem with
it so far, knocking on wood. at times i had the vdimm mod running, with
a 3.3v line at >3.6v and a vdimm of about 3.4v idle and 3.3v loaded and
could go to 250-5-2-2-2 or like right now, i have the vdimm mod turned
off and am running 240-5:4-192-5-2-2-2 at whatever..2.8v iirc. not an
issue. the rig has been running d2ol through most of the last 2 weeks
nights, while during daytime it was either off or having to run whatever
game(s) i chose to run (fear, q4, blabla).

so what i'd like to know is of all users that have sticks killed with their
asus boards in a dothan (adapter) based system, at what settings and
in what slots on the mobo the stick that died was located.

12-22-2005, 04:45 AM

My BH-5 have been run in the 2 dual channel slots closest to the cpu from day one (since it is the only config which allows preserving dual channel and using (unmodded) DDR Booster). Don't know the ram slot numbers but I can verify them to be 1 & 3 or 2 & 4 when I get home.

fordf250

12-22-2005, 06:32 AM

new question what version of cpu-z are you running? I have always run clockgen and cpu-z at the same time.I was using v1.31 when the ram died.

Neova

12-22-2005, 07:09 AM

I've been running clockgen and cpuz on my P4C800E-D, CT-479, Pentium M 740 and Corsair 1 GB Valueram DDR400 in slots 1 and 3 setup since day one with no problems. Well, I blew the mosfet on the first adapter, but otherwise, MB, CPU and RAM has been (relatively) problem free.

This is both before and after vdroop and vcore mods. Otherwise, fully stock MB and no mods on CT-479 adapter (yet).

This could be a i915 chipset only problem.

EDIT - reread Waus-Mod's post and he is using the same MB as me.

Someone who owns both fully modded i865/875 and i915 MBs with DDR voltage taps should log ram voltage readings during an exercise that shows using clockgen and cpuz to see if spikes show up.

I don't have the equipment (no voltmeters) or time to perform such an analysis right now.

saaya

12-22-2005, 08:11 AM

i was running cpuz v1.31

and cpuz and clockgen not starting properly and taking forever to load or not starting at all were the first symptoms.
this seems to have to do with pushing the boards beyond what they are stable at... waus-mod also had his system at speeds it wasnt absolutely stable and then the system crashed/gave him a bsod...

good news, after the damn asus contact person for germany never replied to me i emails asus usa and taiwan and they both replied inmediatly :)
they requested more infos and will hook me up with somebody to have a look at this.

if you have some crappy memory please try to reproduce the issue you encountered and make notes of everything and post them here so i can forward them to asus. lets hope they fix this asap.

btw, this all seems to be related to the ct479 somehow... i wonder how...
doesnt make any sense at all to me until now how the ct470 could cause this :confused:

sky

12-22-2005, 08:15 AM

i know i have been running various versions of cpu-z. most recently (not up
to date it would seem) i'm running 1.30 with no probs. would have to go and
check my older screenies for what version that was. i know i have been using
1.29 and maybe 1.26 for testing. at times i even had eist and i865twk running
along with the other 2.. ahem :D

/edit
oh and seeing / reading about loading times. yes ocassionally it would take
like 10 seconds or so to load cpu-z (when clockgen was already running).
but on average cpu-z takes quite some time to load for me anyway - for
whatever reason, maybe even in the 10s range. i never timed it... but it
felt to long for such a "little" tool anyway. also at times i would get a screen
saying something along the lines of "another instance of cpu-z is already
running" - this would happen when i865/875 tweaker was running and i tried
to fire up cpu-z or something. so close the tweaker, open cpu-z and then
reopen tweaker would do it for me. strange really.
also regarding fsbs.. i have been way beyond 300 (313 iirc) with my fsb and
the ram at 5:4 or 3:2 (5:4 was 250ish) and never had a stick die yet. but
i wasnt ever over 250 with my mem so far iirc. maybe that's the issue. also
i have exchanged the asus nb-heatsink with a something bigger

12-23-2005, 05:33 AM

My board was stock and vdimm was 2,85V
Something says me it's the SPD. Someone willing me to send an DDR333 stick of memory so I can exchange the spd ?

fordf250

12-23-2005, 06:05 AM

It has the spd screwed up or its trying to boot at the settings from the overclock?the setting that the ram failed for me is a stable setting in my 875p-t but I need to set it up to see if it will boot, thinkin its stuck at the speed it was runn in the p4c800 with cg when it failed.

sky

12-23-2005, 06:42 AM

but how would the spd play into this? i mean, my khx3200 come with spd settings of 200-2-2-2-6, i run them at -5. always have, same at 250 (not
that is was anything but superpi stable) but just so. the timings i had them
running at was:
cas: 2.0, ras2cas: 2, ras pre: 2, pre min: 5, pre max: 120µs, refresh: 64µs
dram: 01, perf mode: enabled

also would the spd be screwed up? wouldn't that rather be a bios issue?
something to do with the pm-compatible bios' for the asus boards?

lawrywild

12-23-2005, 08:00 AM

I always used clockgen and cpu-z at the same time (v1.30) and had no problems with my bh-5 or my ballistix...

Astral7

12-23-2005, 08:31 AM

Other than fordf250 has this happened to anyone else in the U.S.?

The reason I ask is it may be possible the difference in current, 230/50Hz in Europe and 120/60Hz in U.S. could have something to do with this.

I am currently running a 740 with 2x512 Mushkin Lvl II and 2x256 TwinMOS BH-5 in a P4P800-SE with no mods. I blew 3 mosfets on a P4C800-E Del and now that is fixed I will finish the mods on it and test with CT-479.

I have a 512MB stick of BH-5(Corsair) that fails at 412MB, so I can test with it. But I almost always have cpu-z open with clockgen and Tw865 - no problems.

saaya

12-23-2005, 02:52 PM

why would it have to do with the source voltage of the outlet?
unless you have a really crappy psu it shouldnt make a real different on the rails the psu produces...

im rather guessing its the spd as well, lets hope just the spd blew or got corrupted for some reason.

there have been reports about corupted and damaged spd chips on tccd sticks on other boards as well and they stop working with certain timings.

i havent tested my memory in anothwr system tbh, maybe its not dead after all?

12-24-2005, 06:00 PM

I've had a Dothan and BH5 for five months, must have crashed hundreds of times. Ram is still alive and kicking...*touches wood* Often times after a crash, I can't POST unless I pull one of the sticks out and just leave one in to let it boot in single channel. Works fine, and then shut off again, stick the second module in and I'm good to go. But I don't think I ever had CPU-Z and clockgen open at once. I've always run with the kyosen vdimm mod. I have a feeling that if there's a real issue, it would protect the ram since it overrides the mobos circuitry to an extent and always gives exactly what the +3.3v rail is to the ram, so next to no chance of a burnout.

I had one 256mb stick of BH-UTT that died in a P4P800-SE. One of the traces on the RAM was all black and ofcourse it doesn't work ever since. I'm not sure if the motherboard caused it or the RAM itself. The motherborad is dead now by the way, after inserting a USB-headset. I hate Asus.

Guys, I think if you do the kyosen vmod, you'll be fine. I crash nearly daily at 3.47 vdimm; BH5 and a Dothan. Hundreds of crashes and the memory is all right. Has anyone using the kyosen mod killed BH5 so far?

I have a P4C800-E and have replaced the Vdimm mod by the Kyosen mod because in idle my Vdimm was 3,3V but when i run Memtest it drops to 3,1V and it wasn't my PSU,with the Kyosenmod Vdmm idle and stressed are almost the same,anyone the same experience?

i can only say that i did the "oldskool" vdimm mod on my p4p800se (pin6 to
ground or somesuch) and i do get wild swings from idle to load judging by
what my multimeter shows. with a 3.3v line at 3.6v, my idle vdimm is like
~3.4v that drops to ~3.2xv under load...sometimes even 3.19v... (3dmark).
that is with an ocz powerstream 520w, not the worst psu in history i'd think.

anyway. i've been running this rig (p4p800se) with 2x 512mb sticks of khx
(3200/512 bh5) for at least 6 months with no issues - for long periods of
time i had the ram running 1:1 @240. nowadays i run 5:4 (ram @192, yea
sucks, i know...).

so what may be interesting is to see what kind of vmods the people that
have dead bh5 ram (caused by an asus board with a dothan cpu) did to
their boards. oldskool or kyosen.

quick poll anybody?

gosh thats scary.
so many unmodded ones. eek. maybe compile really detailed info:
mobo (with revision if known) including mods (and type of mods, vdimm, vcore),
bios (version),
ram (brand&type, size, ss/ds, clocks, timings & volts at death), slots used
cpu (type, fsb at time of death of ram),
psu (brand & type, mods - setting of the rails at time of death of ram)...

and then maybe additional data about the circumstances during which the
ram died. benching, idling, gaming. what programs were running at the time
of death (sounds coroner, eh?)... the works.
there *must* be some common ground here. i cant believe this is all just a
series of coincidences...

just checked ram voltages on the P4GD1 with the ct479 - after crashes the shutdown and reboot sends some voltage spikes that are responsible for the ram deaths - usually the shutdown is +0.2V the bootup +0.4V.

On random times I have seen +1V !!!- from 3.2V it jumped up to 4.2V - pretty harsh...can kill lots of good ram

This is on unmoded board and virgin CT479 - voltage was measured from the slot itself

I did the same to a stick of tcc5 the other day only 2.85Vdimm,saaya says if you are using clockgen and cupz at the same time it can kill ram also.

Same thing here http://xtremesystems.org/forums/showthread.php?t=83398

I have done this many a time on my comp at school with no probs at all what will it do set it then cpuz read it before it is fully set putting it into a affinity or something?

CPU-Z has NOTHING to do with this - even if it might cause a crash for random reasons - the bug lies somewhere else....

Thanks for the clockgen Frank!!!!!!!! It rocks!!! ( now if I only could understa on how to FULLY lock the CI-E ad PCI clocks.. - lol )

CUP_Z + Clockgen has not to be blamed for any ram/hardware casualties....In the boards or he actual CT479 adapters - there might be something that doesn't allow to dischargecertain .................well somebody else should figure that out better than what I am trying to guestimate - since I am talking out of my ass right now.......

Well @ mike...

Then explain what causses the death? ONLY when cpuz+clockgen is opened you get a BSOD, when that occurs say goodbye to youre mem..

I dont want the say that the software is bad... but it ONLY occurs when both are open so explain what it could be else.

For the people that are to scared loosing there good mem. Just run youre dual channel sticks in slot 2 and 4. Because all the mem that died was in slot 1. The second stick that was in slot 3 didnt. So only slot 1 kills youre mem/spd

I also asume its the spd... though i hope that coz my bh5 was pretty good.

Gautam

01-03-2006, 09:42 AM

CPU-Z sort of does makes sense I gotta admit...it does access the SPD chip. Is there any other program that you'd normally run in Windows that does?

Although I don't think its a design flaw in CPU-Z. It has to access the chip to display the info that it does.

Waus-mod

01-03-2006, 10:00 AM

Yes... exactly gautam, Coz cpuz or anything else cant put to many volts through the mem, or something like that. Cpuz does enter the spd, and i think the only problem here.

My bh-5 sticks are fine here . 3.4v 24/7 without any problems . I guess it is a problem regarding some batchs of Asus boards .....

My story - for over 2 years now Ive been playing with the same board&cpu (lack of money :( ) and two diff sets of ram at diff voltages, always in dimm1&3, a set of mushkin bh5s and a set of ocz d43s, both sets are 256x2, and Ive had cpuz (diff versions) and clockgen opened at the same time at least 50 times without any problems (one thing though, I dont run cpuz while upping the fsb, before upping the fsb I close cpuz and after I hit apply in clockgen I reopen cpuz).

i got something like 5 or 6 p4c800e
no problems with bh5,bh6 sticks even on +4v.
the board died but not the rams.
sorry to hear that from you i think is just bad luck.

it`s something like that dfi that killes fx and x2 too..
just bad luck.

My Asus P5P800 i865PE is an BH5/TCCD/Hynix D5 killer. :D

One dimm from a Corsair kit 2×CMX256A-3500C2PT (v1.1) BH5 - R.I.P.
One dimm from a Corsair kit 2×CMX256A-3200C2PT (v4.1) TCCD - R.I.P.
One dimm Kingmax HardCore DDR500 Hinyx D5 IC's - R.I.P.

Blue slot No.#1 on my P5P800 is erasing the SPD of any module I put into it and P5P800 uses SPD information upon detecting the RAM. I've put the kits one by one in the blue slots in dual channel, for each kit the only broken dimm was the one which was in the blue slot no 1 at maximum 2.85V. I use CPU-Z v1.31 and Clockgen in the same time when it's happened, if you ask ...
Dimms now are ok, SPD edit with Thaiphoon - Universal EEPROM Burner. I will try black slots and post feedback soon.

my winbond killer board is a p4p800se. it killed a module of a pair of bh-6 before i've send it to get a vdrop and a vdim. it killed a module of a pair of bh-5 with the modder.
i'm wondering buying a gskill fx 1gb kit, does asus + ct-479 kills tccd also?

ps: sorry about my bad english.

Waus-mod

01-05-2006, 01:51 PM

BIGFOOT WAS RIGHT

SPD = erased, take 1 working bh5 stick and 1 that died with the cpu+clockgen. look with the thaiphoon on both spd ;) see the changes. Also the are no details on my "dead pc3500" bh5 stick, and on my 3200LL there IS

The other thing.. If software can detect an spd, the memory aint dead :D
great news.

01-05-2006, 02:02 PM

Ok i exported the working XMS 3200LL spd into a file. Then i loaded the not working XMS 3500, then pushed update dump, and then he asks left-most Hex value and right-most Hex value. What do i have to fill in?

hmmm all this talk makes me think it would be wise to control the vdimm externally, think i'll build an external vdimm board and disconnect the MOSFET

waus-mod
why not ask the guys that did the programm? someone has to know it.
to be on the safe side, i dumped both spds of my beloved khx3200/512 bh5
sticks - you never know... will continue to dump any other modules i have
that i *need* :D like my mushkin bh5s and some bh6 and ch5-based rams ...

oh and johnny bravo... if it is really only the spd that gets erased or rewritten
and no real physical damage to chips is done, i think we now have all the
tools we need to have.
though an external powercircuit for the ram may still be a good idea given all
this volt-spiking. though what i am wondering about is whether asus used the
same circuitry on all of their p4 boards (p4c800, p4p800, p4gd1, p4gplx,...)
because from what i can see in this thread, at least the first three in the list
above have "killed" ram so far. whether that ram is truly dead or just the spd
is borked remains to be seen - it also needs to be verified whether thaiphoon
can fix the spds so as to fully restore the memory to work as it is supposed to.

also wondering. maybe lifting a mosfet and using the kyosen vdimm will do
the trick, but then we wouldn't have any real filtering in the vdimm-power
circuit. nothing to smooth the voltages that come from the psu. that may
need a little bit more circuitry (than i could think of). if you or anyone has
the knowledge to do something like that (hipro?) please go ahead

Yes, that is what I was saying, memory is not completely dead. For example, sticks that don't work on P4Gd1, do work on my old gigabyte KT266 board.

However, I don't really understand this SPD thing. If it gets erased then why is it not working if I set timings manually and then insert that module?

I will check that program and I do speak russian a bit :)

If I am right, you can also change secondary timings

audiojunk66

01-06-2006, 01:58 PM

Someone should try to put the SPD of an old BH-5 module on a BH-UTT module. It may fix the incompatibility problem between the 465 and 475 intel chipsets and UTT memory. The IC's should be physically the same so the only problem could lie in secondary timings programmed in the SPD.

Nice that you mentioned that because when i read about this program today(didn't know the program before) it was the first thing what slipped through my mind,but i'm first wanna know a little bit more about this program but can't find much info yet:(

Chhers for clearing that up sky, havent been keeping up to date on this thread. I had noticed dips in my readings during superPi/other benchmarks, the vdimm supply would drop up to 0.2 volts so I decided that an external supply circuit was needed. I'm currently waiting on the ok to see if I should remove the MOSFET or not when installing it. Will check back with my findings as soon as I get it up to speed.
