Issues on Asus p5p43td - Page 11

hmm, am i awake or asleep?

---

But i only had maxmem on when i did the speed test,
But you see, i still get memory error, while im way under spec

But could it be, that cuz i dont enter sub timing mannualy, i get that ram errors?
Maybe it doesnt differ in speed much, but i could generate errors?

--

Now i go get some sleep, its like 04:30 over here, gotta wake up early toomorrow..,, NO!!!!!!!!!

hey, came new to the discussion.. can you post again now all your actual bios settings? maybe a pic? another thing, maybe a bios update would grant you more settings and eventually a higher fsb wall? i dont know which version your board got and which is the newest, in some cases it could help

Welcome to this epic thread smex!
There you go with my settings
// Cool i just quoted myself
There isn`t afaik a newer BIOS and even if there where the p43 FSB limitation stays. (With this board and the settings above it`s 441MHz)
Maybe i should write a guide how to get the most out of this board!
My friend Pre` --> Why the heck didn`t you allready enter the subs manually??? I achieved a nonbootable state with some wicked subtimings so of course they can produce errors (which are not wanted )
But like I wrote i get the FSB like you (later) and see what bandwith i get (without errors) and get back to you!

So dear Pre` this is what it should look:
http://img51.imageshack.us/i/maxxmem2k3051.jpg/
And just to lol a bit the timings @533MHz are much tighter that what you should have as timings now @high clocks. The same applies to the subs. If you change them to something like i got them you should get: No errors | higher bandwith | and a happy Pre`

I Currently have no photocamera for a bios picture,

But i used your settings that you provided with the pictures, even tried different pci-ex speed. And in the 40 hours of bios testing, i have test all settings combos.

I also tried your timings, even subtimings from bios picture. Then i still get errors.
Today i entered timings mannualy, that i need for my XMP profile. But some numbers needs to be higher, then i can select in the bios. (So i can't set the right timings, that it needs)
The higher timings i enter, the lower the bandwith gets. Lower then i get @ 666 6-6-6-16. With no errors. I Geuss the errors cause my bandwith to suck.

the reason for all these errors, are still because the motherboard doesnt detect right ''memory profile'' and always puts it at the same speed with same timings.

Today i got it posting @ 1700mhz ram 10-10-10-30 (with ****ed other timigns)
But it wont boot into windows.

I'm abbout the give up, its like im waisting time on this. If i worked all the time, i invested testing with bios settings. I would have a i7 pc.

So plz guys, do you have any last suggestions for me?
(Next time, i only buy memory thats in the QVL list for the mobo)

Hi, did you ever try to setup some delay between the channels, cause you are pushing the northbridge so hard with 4 dimms running with high frecuency. This maybe cause some synchronice problems, i mean this hole system it's an sinchronous divice running in that way it could happen that the chipset cannot handle both channels without giving you errors because somewhere during your test the signal of your channel b "corrupts" the signal from channel a.

By the way high frecuencies are not as good as many people could think, atleast it's what i think, you may gain at the best scenario 2-3% performance. My advice just relax your dimms timmings try to use T1 + low Cas Latency and 1:2 or just 1:1 fsb:dimms ratio, and of course put some skew between the channels. I'll try to get some info for you tonight or tomorrow morning.
PD: sorry if i make mistakes during my explanation.

But Pre` like i wrote 10post before and about 3 times forget that XMP-profile!
What you got, these 1416MHz isn`t that bad and my bench-pic with these settings are
much better than that you posted@1416 and i even got a higher latency (don`t ask why) + i got -25 instead of your -24...
This 1416MHz with 9-9-9-24 should be allright, just work on subtimings.
Something like 5-72-7-6 should do the job. Don`t go under 5 or 72. Maybe raise to 6-72-10-7. But this shoul pretty much the job.
//------------------------------------------------------------------
Hi asigan, welcome to OCN!
thx for your advice but look i got higher clocks than him 4x4GB RAM and never had to delay or advance some rows (Which doesn`t mean he shouldn`t try or that i`m smarter than you!!!). But thanks for your thoughts.
If he didn`t already spend 100hrs to fix this issue i would sugest him that too...
Thx for joining OCN and posting this lovely epic thread!
//-------------------------------------------------------------------
What could help him is to delay the NB just a touch 100ps is the lowest you can set. I would try that. I played with these settings (delay NB/CPU) to go over the wall of 441MHz FSB. But i think:
Pre` you should give some last trys without XMP. 1416MHz some timing and subtimings above and the NB delay of 100ps (its called NB clock skew).
If this doesn`t help, lower the clock loose timings and come back to this game in a few weeks. Frustrating but you could invest that time in what you have to do:
- Working on being not sober
- burning these funny herbs
Cheers lads

I was only mentioning the XMP, because its the only ''timing list'' that has 1600mhz on my memory. I tried too duplicate the timings manually, but then i get errors.
And there is no normall 1600mhz JEDEC profile on my ram, only the xmp has 1600mhz.
Thats why the motherboard doesnt register the timings correctly in bios i geuss.
( I Still think, cuz the memory doesnt support the timings required for XMP that thatsway it doesnt work)

I've tried to delay 50/100ps on both channel, or only one channel. The result was still the same.

The XMP profile says 1.65v, 1600mhz 9-9-9-24.
With manual settings i know used 1.5v to 1.65v till 1.70v - 1416mhz 9-9-9-24 untill 10-10-10-30
And the problem is, im 200mhz under specs, but still get small memory errors.

I've tried literally every settings in bios, from OC charger, till whatever

I geuss i'll try to tweak the ''sub'' memory timings, till i find a sweet spot. That gives no errors. (if there is one)

and btw. This epic thread, is never gonna end muahahah

ok to begin.. i will take eiht´s last 5 screenshots as example and tell you everything i am seeing there.

# first.. he is using four ram sticks, what decreases the max fsb and makes higher overclocks unstable.. try it with two sticks
# ive seen cpu margin enhancement is on normal, set this to performance
# set cpu and nb clock skew to auto first.. you can try messing with that later but remember NB got to be 100 lower than cpu.. for eg nbcs 200 and cpucs 300 and so on..
# the nb is at 1.25 which is low if you want a higher fsb, for my p45 i need 1.46 for 481, but beware.. the nb got to be properly cooled
# ram timings: tried auto? what happens then?! i´d try the manufacturers spec as shown in cpuz, but first switch to auto to show which values the bios is making..
# pcie freq is 105 ?? from what ive read this cant be good.. if something is unstable you can increase or decrease it by one or two but not more, ive heard its making problems otherwise.. i would leave it on 100..
# strap to NB.. was it by stock 400 or 333 ?! leave it on the original value..
# and last.. disable the tm function when you are sure your cpu is cooled enough.. it costs performance in some cases..

thats all i see in eihts screenies, try theese tips and report.. i know my experience is from a p45 but there should be a similar behavour.. cheeers




edit: everybody of ya know how to properly use prime? ;P

The thing is Mr. Eiht stuff is working good.
So his settings are %100 stable.

Its me + Gore that has stability problems.
(if you want, read the whole topic, to understand where we are )

I will try:
