E6600 on a P5B DLX. Not primestable at 320fsb, Bad Ram?

[zizo]

So when does Asus want to release a new bios? It seems 0507 is not working for most people.

[Reite]

Still up and running after 50min, Damn i didnt know a bios could screw up that much. Il do a memtest afterwards and se if it is any difference there.

And for all its worth my timings are abit slacker with this bios, it was 5-6-6-18 with the last one and 5-7-7-23 with this one, could that be the cause of it?

[lawrywild]

Can't you set the timings yourself??

[zizo]

No, most likely your ram is fine, just like mine. It's just the bios that is missed up. Even with 0507 I can run my ram @1000 with 4-4-4 timings and divider, but FSB doesn't go higher than 320.

[aggybong]

With the 507 BIOS, what timings are you guys trying?



I'm not sure if we are supposed to adjust the ones with the value of 10 or not, and is write recovery supposed to be 6 or 5? Or maybe even 4 :P
This is with OCZ PC2 6400 1GB EL Dual CH Platinum Edition XTC rated 4-5-4-15 (What a name)!

[Reite]

Well i tried to set the timings to 5-5-5-15 on the 0507 bios at 320fsb but then i couldnt get into windows. I will try it with this bios after ive run memtest.

Why is TRFC at 42? Is that the default setting? Seems a little loose. Might want to try 35.

I'm not sure the timings are actually being set to 4-7-7 when using some of the BIOS's. Just because CPU-Z says so doesn't mean it's true. CPU-Z also says my VCore is over 3v.

This is a good board if you can get everything straightened out.

[aggybong]

Most seem to say it's a good board, but for those of us who are having problems it's hard to recommend it to others.

The thing that bugs me the most is that I don't know if it's my memory or the motherboard\BIOS.

[Andypro1]

Ok i just tried the 0502 bios solution, and prime has been running perfectly for 30 mins now at 333fsb haha, il see if it keeps up=)

Nice Reite! I have been unfortunately dual priming my supposed 'bad' stick of ram for over 1/2 hour now as well, (and memtesting it). So perhaps it's the slot on my mobo that's bad, or maybe it just can't handle both sticks at once ;(

Perhaps I should try 0502 also, just for kicks. First I'll up my fsb to 333 and try priming again with each stick separately.

EDIT: Ok, clearly both my ram sticks are fine (or both extremely bad). Both are fine at stock, and both fail with their failure rate proportional to the fsb speed. Ie: 266 fsb: no failures. 316: a few after a while. 333: a bunch right away. I'm going to flash to 0502 now.

[Andypro1]

Woah! It appears Asus has taken 0507 off their site and put 0405 back up! At least for the p5b deluxe/wifi. Perhaps they've been having as much trouble as we have.

uhh.. no they didnt im looking right at it..

[zizo]

Use the FTP server they are all there. ftp://ftp.asus.com.tw/pub/ASUS/mb/so...uxe%20Wifi-AP/

Sierra, what bios are you using? I used everest, memset, and cpuz and they all show my timings as x-7-7-23 with 0502. I tired many different timings but didn't help; however, 0507 shows the right timings.

[Andypro1]

uhh.. no they didnt im looking right at it..

Oh. Yea I assumed it was still on their server. It's just that they are not offering it anymore if you go through their support site and pick the motherboard, then pick bios. They used to be, but now they're back to 0405.

Anyway, long story short with my stuff: I tried running at 333fsb with, get this, 1:1 ratio, 6 6 6 18 6 42 timings and 2.15V, and it's just a plain no-go. My ram simply hates the fsb being higher than 300. So 2.7GHz is all I get. I'm a little concerned that on the POST screen it says "PC4300," because these modules are clearly PC6400. However they sure are performing like PC4300 pieces of crap. Kinda wish I could RMA them but they do appear to be quite stable at stock fsb, so ;(

[Reite]

hmm thats strange andypro? did u try the 0502 bios?

On my part this bios is so much better. Ive been priming for 50 min now with 350fsb, and the memory has magicaly changed its timings to 4-4-4-12 without me doing anything=)

0502? Whoops, I'm a moron. I was thinking you were using 0405, but that's because I wasn't thinking. I guess I can try 0502, may as well!

At least I know that I'm 100% dual prime 24/7 stable at 300fsb / 2.7GHz. I need to find a hack to disable stupid windows activation so that I can keep messing around with this stuff (I really don't feel like having to call them every 3 days). heheh.

[Reite]

Well my system is pretty much stable at 350fsb, ive been running stressprime for over 4 hours now without errors

Anything over 350 quickly gives me error though. It wont boot at 375, and at 365 i get the "rounding" errors in prime after a few seconds. I think il try the 0405 bios and see if it is any difference there

Ah yea. The infamous SP 'rounding errors.' Oh how I loathe them.

Hey, can you check next time you reboot what your POST screen says with regard to your ram? I'd be interested to see if yours reads correctly.

When you get the splash screen press tab and then look for the line that says something about "PC-XX00" ram or something like that. I want to know if yours correctly detects your ram speed, because mine doesn't. Although CPU-Z does.

[Reite]

No it doesnt, it says 4300 interleaved or something. But cpu-z shows it right.

I tried the 0405 bios now and i did not like it at all, i tried booting 350 fsb and the same settings as i had on 0502 and it wouldnt let me load into windows at the 2 first tries. after that i went back to 0502=)

Ah, thanks for that.

I will slap 0502 on mine tonight and give it a go. Mine also says 4300 interleaved.

[Reite]

Damn this is a strange board. If i set my DRam frequency to auto it will give me 5-8-8-2x timings and 700mhz ram, but if i set my dram frequency to 700mhz it will give me 4-4-4-12 timings...

And if i set the dram to auto and change the timings manually i cant boot...

And im on a new fsb wall it seems, i will get the rounding errors at once if i try to prime at 360fsb, same as i got at 333 fsb before i changed bios. The cpu test only goes perfect. and the "stress some memory" test fails after a few sec... There dont seem to be anything i can do about it either, i think il just have to wait for Asus to release a better bios if noone know how to get past this wall..

[Andypro1]

Yeah. I think there is still a serious issue with the P5B series with regards to many types of DDR2 ram. I have no idea if firmware updates will fix this issue, but we can only hope!

[SIOUX]

Ive tried to run memtest too, i got alot off errors within the first 10 min. Il try the same as Andypro.

One more question though, im having trouble flashing my bios to an older version, cause i havent installed a floppy drive in this computer, and the asus update wont let me flash to an older version. Anyway i can override this?

Asus update can actely flash to older bios with no problem. you have to choose "options" and the check the box that says "BIOS Downgradble"

[Reite]

haha damn thats stupid=) thanks. I hope asus releases a new bios soon

Ah, Reite you are a genius!

I just put 0502 on mine, and what do you know, it's dual priming large ffts at 333! Unreal!

The only difference I can see (besides the bios number) is that it set the ram to 5 7 7 23 or something ridiculous like that. Did you change your ram timings back or mess with the ram voltage? Also, how high did you say you took the fsb stable on bios 0502? Thanks. (woot!)

[Metroid]

It depends which prime you are running.

I was with Orthos beta the newest version and so far just 20 minutes stable at 9 X 400 = 3.600 E6600 after many errors appearing, I could not pass of 20 minutes. So I changed the version to SP2004 and so far 4 hours stable. I have to say trying beta versions is no way good, if you are speaking about stability.

Is the same if you test memtest86 for ms-dos or memtest for windows. We cannot compare, Ms-dos version all the way, it shows true erros.

I'm testing the beast as it has to be tested
