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

**aggybong** · 08-21-2006, 03:33 PM

Yep, same story for everybody with this motherboard and OCZ ram. It's a mystery

And no, the timings are locked at x-7-7-23.

**Tony** · 08-21-2006, 05:08 PM

Looks like a bad board there bud...the board set the timings with cmos, if cmos is not taking you may have a faulty board.

OCZ memory on the whole is working fine, I have the DS3 installed right now with SOE 800. I have had ddr1000 and 4x1gig dimms at 900+ pretty easy.

I keep saying this and will continue to in every thread i see...if you need help we are here for you. Please make sure you understand how the boards work and how straps work first though...it is mighty important as it effects the ram in a huge way.

**aggybong** · 08-21-2006, 05:27 PM

I think it's the BIOS, not the board itself. It really doesn't like OCZ ram for some reason. There are now multiple reports of the 502 BIOS being the only one working correctly, but at very loose (and unchangeable) timings.

**-n7-** · 08-21-2006, 05:35 PM

Goddamnit

I just ordered this on the weekend since i'd somehow overlooked this thread.

So you guys are saying that to get a decent FSB, one has to use the 0502 bios, which forces stupidly loose RAM timings you cannot change?

edit: You guys all have OCZ RAM?

Or is this issue with all RAM?

**aggybong** · 08-21-2006, 05:46 PM

I've seen most of the reports come from people with OCZ ram (both Platinum and Gold editions). I'm really hoping theres a BIOS fix, or that OCZ can fix it on their end.

**Tony** · 08-21-2006, 05:51 PM

I have a P5b here and it will be tested soon

**aggybong** · 08-21-2006, 05:52 PM

Do you just have the P5B? I'd like to see testing done on the P5B-D

**-n7-** · 08-21-2006, 05:58 PM

Whew!

I have Team Group DDR-1000 coming for my P5B Deluxe, so hopefully i won't have these kinds of issues.

I suppose time will tell when they arrive.

**Andypro1** · 08-21-2006, 06:19 PM

Um, I didn't say the timings were locked in 0502. I haven't even tried changing them. I'd assume they work normally. However I'm going to leave them on auto configure because I just activated my Windows again, and if I continue to mess around in the bios I will be asked to activate yet again.

Btw, I have Corsair ram in there now, not OCZ. There's nothing wrong with OCZ ram except one of my sticks was bad. They might require a slightly higher voltage than other DDR2-800 modules, but as long as you can get it to boot once you're fine. Then just set the Vdimm and everything's good.

Don't worry, P5B Deluxe is quite a good board. It's just that the BIOS is obviously not yet mature (to be expected).

**aggybong** · 08-21-2006, 06:23 PM

Nah, they are locked to *-7-7-23. It's been confirmed by multiple people, including myself.

Oh ok.

**sluzbenik** · 08-21-2006, 06:33 PM

How are you guys doing with setting RAM dividers at anything other than 1:1?

I can boot but am not Prime stable at 350x8 with an e6400, not sure if it's heat or what. BTW, I know a lot of people are questioning the temp readings as well, and I let Everest's stability test run and watched the throttling kick in at 84c, so I'm not sure they're really that off. A degree or two maybe.

My real problem is this - at 300x8 with RAM at 4:5 I cannot boot into Windows. This is nuts because I am still at 750 on Corsair 6400 (DDR 800). I see no reason to increase the voltage at that setting.

Gonna go run Memtest for a bit on that setting.

---edit

Confirmed there's a divider issue still in 508...Windows Memory Test fails instantly with a 4:5 divider at 300x8, but is fine at 266x8. At 1:1 it also looks fine after a couple of passes.

Can anyone else comment? I am going to whine to Asus tech support, if everyone else is having this problem, then it is a BIOS issue.

**Reite** · 08-21-2006, 10:57 PM

Have you people who have trouble with memory timings tried to change the Dram frequency in bios from auto to 1:1, and then set timings from SPD? Thats what i did to get the timings my chips are certified for; 4-4-4-12..

Anyone have any idea how i can get past this wall though? 350fsb is 100% stable in orthos, 360 will fail after a few seconds no matter how much voltage i put on the ram or the vcore, the CPU test in orthos is stable though.

**Levish** · 08-22-2006, 05:49 AM

My wall is around 370 (with a e6400)

1gb corsair xms pc8500 kit

Running the latest bios 0507 going to switch to the older 0502 later tonight which will hopefully let me go higher.

**zizo** · 08-22-2006, 08:06 AM

Alright, after one week of whining about bios 0507, I thought I should give it another try. It's amazing that I couldn't go further than 325 first time and now it's unstoppable! FSB 1.3v, NB 1.25v, vcore 1.415v bios, ram 2.3v.

i had rounding issue on orthos with 0507 @ 333 Fsb and i'm doing fine with 0502 my ram is corsair 6400 XMS2 C5, i really think 0507 is not able to set timings correctly for my ram...and as some of you stated, it could be just related to 6400 modules.

i'm just too lazy to make de 0507 works fine, just waiting for assus to fix the issue in next one

What did you change? That's quite an improvement

Could we get a list of the exact BIOS settings you used?

**DjLeco** · 08-22-2006, 12:00 PM

Same question,waitin' for answer(s)

**-n7-** · 08-22-2006, 04:08 PM

This is insane.

I have seen a large number of people with great success with this mobo, where they can run over 450+ 1:1 with proper RAM timings, & also seen a large number of people stuck at low FSBs with incorrect RAM timings.

There's gotta be something to this story we're missing...

**zizo** · 08-22-2006, 07:05 PM

I have no idea what was wrong with it the first time. I tried all the ram timings and every voltage increase. I guess one week of burning did the job!

So here are the exact settings. Everything else is default except on board audio and wifi card which are disabled.

**aggybong** · 08-22-2006, 07:19 PM

These are the same settings you tried last time? What about the devices you left enabled\disabled? Also, the biggest help would be to download Memset and post a screenshot of the timings it shows

**zizo** · 08-22-2006, 07:23 PM

No 965 support!

I used same exact settings. Right now I can boot with different timings and setting with no problem. It's not picky at all. Very strange indeed.

**aggybong** · 08-22-2006, 07:24 PM

The latest beta does. You can get it here: http://rv.page.cegetel.net.perso.ceg...mSet22beta.zip

**zizo** · 08-22-2006, 07:32 PM

**aggybong** · 08-22-2006, 08:05 PM

Hmm, all of your timings are tighter than mine besides "Read to Precharge (tRTP)

Unfortunately I'm tired of testing out different settings today, so maybe I'll try tomorrow
