let me start it 1st

F2-6400CL4D-2GBPK is ok with DS3, and CPUZ report it wrong it is CL4 not CL3
it boot with 1.8v and just adjust to 1.9v at bios, everything is auto

**egyteam** · 08-02-2006, 10:38 AM

what about F2-6400PHU2-2GBHZ with the DS3 ? does it boot on auto ?

some users reported it is ok but if no one going to post it, i will do the test

but i think that is no problem

accourding to Andre Yang

so it is no problem i believe

**GSKILL TECH** · 08-02-2006, 01:33 PM

DDR2 800 2GBNR is ok on DS3 also

**LordShadow** · 08-02-2006, 02:52 PM

Hey,

Im afraid your theory about the NR RAM is incorrect.
I have the said RAM with the DS4 motherboard and it simply will not boot, however using some generic RAM it will boot.
There are many other people at forums.overclockers.co.uk with the same problem.
I only hope that Gigabyte release a BIOS to fix this problem.

why?
DDR2 800 2GBNR only need 1.8v to run DDR2 800 and i did boot up with everything auto in bios.

when you change CAS from 5 to 4, CPU-z show correct CAS ?

**LordShadow** · 08-03-2006, 02:27 AM

Why is the question I would love you to answer lol!
I have also tried seriously underclocking and overvolting the memory slighlty (up to 2.1V) and it still will simply not boot.
It could be that the board is forcing it to run CAS 3?

Perhaps yours works and ours didnt because we are using Conroes and you arent?
other than that i can see no reason.

in that case you should contact gigabyte. cuz we can't control that
also sorry to say we do use conroe and no problem for F2-6400cl4d-2gbpk and f2-6400phu2-2gbnr. if you use f2-6400phu2-2gbzx and f2-6400phu2-2gbns. that is incompatible i already said

**LordShadow** · 08-03-2006, 02:43 PM

I think it may be Gigabytes fault as there are many other forms of memory not booting in this board without help.
I am just hoping that they release a BIOS to fix the problem.
Also what voltage do you think would be safe to use with the NR RAM?

for DDR2 800 2GBNR and 2GBPK is good for 1.8v boot for sure, i tested 10 pairs and all of them boot no problem.
for 2GBPK i need to use 1.9v 24/7 stable
for 2GBNR just use 1.8v is good 24/7
for 2GBHZ i can also boot with 1.8v and change to +.3v and it is 24/7 stable and +.5v can reach DDR2 1000

right now DS3 is good on divider
533, 667,800, 1066 all work
but P5b DLX 's 533 and 667 are usless to me... unstable
for ex:
P5B 320FSB with 667 divider is DDR2 800.... error on ram... not stable
however
P5B 266FSB with 800 divider... no problem at all.... 24/7 ok
weird

and this problem is not happening on DS3...

**LordShadow** · 08-03-2006, 03:01 PM

Im running my system now with some generic RAM.
DO you think it would be worth trying to overvolt the RAM and then seeing if my NR would boot? It could be that my DS4 is undervolting it....
If so how much can I overvolt it by without causing it harm?

humm
try 2.1v and see.
nr doesn't like extra voltage
it is design with low volt system that is why

**LordShadow** · 08-03-2006, 03:37 PM

I now have 1 stick of my RAM posting

.
I have overvolted by 0.3v in the BIOS and also manually set the timings to 5-5-5-15 and it is now happy, thankfully.
Will try to get 2 running dual channel asap.

Thankyou very much.

EDIT : Okay it now seems as though despite occasionally poisting it will not boot into windows. I shall have a go at getting it stable in the morning.

it is DDR2 800 2GBNR riht?
what bios version u use?
try everything auto and see it boot or not
(clear bios and see it boot or not)

**vinboy** · 08-03-2006, 11:01 PM

can I assume that the G.Skill F2-6400PHU1-1GBNR will work?

**LordShadow** · 08-04-2006, 01:25 AM

Yes Ive got the NR RAM.
Im going tot ry to update to the latest BIOS available on XS now, and see if it will boot. Will report back whether it will boot at auto settings shortly.

**LordShadow** · 08-04-2006, 02:00 AM

Hey,

Ive updated to F3b BIOS for my DS4.
Tried to boot NR RAM at defaults. No boot.
Tried slackening timings. No boot.
Set timings manually + set memory to run at 400Mhz + overvolted by 0.3v. Boot and system running, havent stress tested it yet tho.
Sounds like an undervolting issue? (EDIT - It doesnt now appear to be being undervolted, speedfan is reading the voltage as correct)
Is there any way to measure the actual voltage going thru my RAM?

Thanks.

EDIT - AHA! Ive checked the timings on CPU-Z and the RAM is running CAS 3 despite me setting it to 5 in the BIOS and the BIOS reporting it as 5.
This surely is the problem. Any ideas on how to fix?

Sorry for all the questions, I really appreciate you being on these forums, its a real help. Thanks.

**Cobalt** · 08-06-2006, 11:23 AM

I'd like to report simlar problems to LordShadow. My NR won't boot at stock. At first I thought it was the power supply because it was powerful enough to run the gfx card but after a bit more trouble shooting and a PCI gfx card, I realised it was probably this. I didn't try some other RAM before because the NR was reported to be OK. I've managed to boot with some cheap DDR2 and set everything manually so its all working good now. Timings were detected correctly but the volts were too low. Seems to be more of a problem with the mobo as it should really have a default a bit higher than a measly 1.8. 1.9 should really be a minimum for compatibility.

**LordShadow** · 08-06-2006, 01:56 PM

Cobalt, what settings did you sue to get it working? (i still cant get mine 100% stable).
Also what BIOS are u running?

Thanks.

Same here mate, e6300, DDR2 800 2GBNR, 5-5-5-15 +.3v in the bios (f4c), no chance of getting into windows because I cant even get it to post, 1gb kingston 533mhz boots fine on auto. I love my ds3

**Ozan Baseski** · 08-23-2006, 09:38 AM

dear friends

ı use ds4 end gbns but ı cand work it
wich bios ı most use for to boot my pc ???
any body can help me

thank you

Hello guys,
Does the GSKILL PK compatible with Asus P5B Deluxe?

thanks
