Kingston D3208DW3T-5U BH-5 ??

[ACE 256]

Thanks for sharing what you've found.

 

Here's some settings that I've run before

and with 3x 256MB BH-5:

233MHz-x10-66MHz-1:1, 1.675v-1.6v-1.7v-3.1v

E-A-E, 9-2-2-2-2.0, 9-12, 2-2-4-3-2-2-3

3-10-3-10-3-10, E-E-F-E, E-E-256MB

APIC enabled

 

Do you have a copy of the S&M utility, which is great for

testing RAM, CPU and possibly PSUs in Windows? I've

found it's excellent for detecting errors and issues much

quicker than many other methods of testing for stability

within an OS environment.

 

Of course there are other things I run also, but I usually

start out with S&M first and then move on to other things.

 

Memtest is good to run from a non-OS environment, but

it will often not reveal errors that can be found when

running in Windows. You might already be aware of that,

sorry if that's the case. I'm hardly trying to speak down

to you.

 

If you don't have a copy of it yet and are interested,

here's a link you can download it from -

Hmmm I always used mem test and prime....Ill DL that and give it a try if i can get my dial up to work on my desktop .. I know its sad 500FSB + an X850XT PE and on dial up :sad:

[medianOCer]

Yeah, I like memtest too and for intial testing before booting into Win or whatever.

 

Prime works pretty good too, but usually you'll need much more time spent with it.

To get a general (and quicker) idea if you need to be tweaking your timings/settings

I like to use the S&M utility. After that then I move into other progs like Prime and/

or others.

 

I hear you on the dial-up routine, but don't beat up on yourself about that. I mean

at least you have that, rather than nothing at all.

 

Best to you.

Update: I droped my Slews to 3 and i seem stable @ 2 2 0 11. Thow i dont see mutch of a effect in performance. I tryed 2 1 0 11 and it too seems stable but i get random hard locks.... I think its my CPU making it hard lock as iv never see memory make a system hard lock...it chould be the mobo too come to think of it... maybe ill try bumping the chipset from 1.8 to 1.9.....

3-10-3-10-3-10, E-E-F-E, E-E-256MB

APIC enabled

 

Is thare a performance gain to running APIC enabled? im running "APIC Uniprossesor" whould that be the same ??

[ACE 256]

Update: after almost 8 hours of testing, Strengths 6 and slews 1 seems to be the most stable. I can run with CPC enabled at: {1.9 Chipset Strengths 6 Slews 1} but again I get random hard locks but cant find a single error in prime or memtest.. I only get ~30MBs boost in sandra with CPC on so I dont see the benefit of trying to get it stable with it on... I ran memtest over night again @ 2 2 0 11 @ strengths 6 Slews 1 and all my errors are @ 1023 and 1024 so i think maybe swapping mem sticks around might help....

[ACE 256]

Update: I am now running ( as i post this ) the = to 2 0 0 11.. Im to layz to post exacts when pics are way EZer :nod: Alphas 0 0 2 2 2 0 2.... Is prime stable for a little over an hour now... Strenghts 6 Slews 1 is definitely a sweet spot for me ..

[ACE 256]

Update again: My Tras settings have now changed ( due to strenghts or slew rates ? Or timings set in NF2Tweaker? ).....my fastest Tras setting is now 7 .... 3862 @ Tras 11 to 3870 @ Tras 7 #s are avarage of 3 runs to rule out variation.... A tras of 5 runs and is slightly faster ( 3872 ) but i get random reboots.. All timings are realy applyed i get a small boost in Everest latency every time i droped them ( best score so far 64.1ns ) Has any one seen results like this ??

[ACE 256]

Well i currupted windows buy playing with a Tras of 5 .. But im testing on an old 4Gb drive with XP installed not my good drive ..Ill be back to testing after i reinstall on the 4Gb......

[medianOCer]

I have had Win corruption at around 5 or 6 tRAS as well, but that's with using CPC

at 1. I've heard from others that using a CPC of 2 might allow using lower tRAS

settings, unsure on that as I haven't tested that yet. That's just what a few people

have indicated.

 

If you don't have a backup BIOS plan, such as an extra BIOS chip and/or a BIOS

Savior, then you might want to consider getting either one of those. Just in case

you'd run across a no-boot scenario and a CMOS clear doesn't get your rig booted

back up.

 

APIC and ACPI (as in Windows under Computer Type) are different. APIC being

disabled might allow higher OCs easier. I have it on because I'm not running a

real aggressive OC (as in 250MHz/500DDR or higher), and my system seems to run

well with it on.

 

Commonly, under Computer Type in Device Manager, there will be the ACPI

Uniprocessor PC designation. That is if you haven't changed that to Advanced

Configuration and Power Interface (ACPI) PC, which I usually refer to as ACPI

(ACPI) PC.

 

Quite a few DFI NF2 users have reported that they get smoother running rigs by

using ACPI (ACPI) PC instead of the ACPI Uniproccesor PC designation. Some

have even commented that it may have helped there OCs a bit too, though that

might be more of an unknown and whether it will or won't help OCing may vary.

Well i gave up. Its to hard to look for data curruption and the boost i got from a low Tras is not worth the risk to me. So as of right now (im running my good hard drive)

T(RC)11, T(RFC)13, CAS 2, T(RP)0, T(RCD-W) 2, T(RCD-R) 0, Alphas 0 0 2 2 2 0 2,

250 ( 500DDR ) x 9, [email protected] core, 1.6 AGPv, 1.9 chipset, 3.3 Vdimm, CPC disabled, and ACPI enabled ( assuming its correct in this pic )....

 

Does any one know of a way to force/run a CAS of 1.5 or lower on NF2 ??

[medianOCer]

Nice, I see you've got the ACPI (ACPI) PC going there. You notice much, if any,

difference with it set like that?

 

My setup seems to run smoother with it, as opposed to using the 'stock' ACPI

Uniprocessor PC in Windows.

 

I could be incorrect, but I think CAS 2.0 is the lowest tCL setting available with

these NF2 boards.

 

What DIMM Driving Strength (DDS) and DIMM Driving Slew Rates (DDSR) did you

settle on? Just curious if those seemed to help you at all.

 

My single sided sticks, which have 8 chips per side, seem to run very well with

DDS=3 and DDSR=10. The default/auto values for single sided sticks (with my UI

board) are usually DDS=2 and DDSR=11.

 

I think the default/auto values for the DDS and DDSR are DDS=4 and DDSR=11,

for double sided sticks and as far as I know about them on these NF2 Mobos.

With double sided sticks I've wondered if DDS=5 would help, and maybe also

DDSR=10 might do something too? Maybe not, or maybe different values than

those would be better. Unsure, as I don't have double sided (16 chips) Winbond

sticks. Anyway, I think I've already mentioned something about that in here. So

just disregard that if it's redundant.

 

Take care, and back with you later on...

[ACE 256]

Strengths: 6 Slews: 1 seems to be the best...

Alphas:0022202

13RC, 15RFC, 11RAS, 1R 2W 1RP,

 

I always get 1 error in S&M: 1 Single address error and 1 single bits error. always on pass 3 ~ 75% Iv tryed 2.5 3 3 11 same thing it doesnt seem to be effected buy timmings ( alphas or otherwise )..... and i still get an error in memtest @ 1023... so maybe i have a weak spot in one of the sticks Ganna burn in some more maybe i can get the weak spot worked out.

 

As for ACPI i honestly cant tell.... it seams "crisper" and "smoother" but i donno it might just be me.. if thare is a dif. its vary subtle...

[ACE 256]

Im burning the ram as i post this ( on my lappy ) I get errors from 950~1024 all in test#5 always "Good:ffff3fff Bad:ffff7fff Err-Bits:00004000" Im looping test #5, ganna go for 24 hours and see what that gets me.....

 

As for your bios suggestion. Im ganna get a bios savior when i get the free $ ...

But now im just using NF2tweaker to set the alphas. Setting bad alphas and running the ram out of 1:1 are the only things iv seen currupt a bios....

 

Will Update ......
