E6400/P5B Deluxe overclocking nightmare Can anyone help

[loki5667]

Problem with the auto settings is that I don see myself being able to really use these settings.

Stock speeds TAT shows idle 37/35. Using 401/802 settings and auto for voltages the temps jump to 54/52.

That is with a Zalman CNPS9700 installed. Those temps seem way too high just for idle temps

Err, i don't think so...

Auto increases as overclocking is increased AFAIK, so unless you've measured with a multimeter, i doubt that's correct, aside from maybe certain cases.

While i personally haven't messed with auto, i recall comments from people asking with their voltage was reading so high when they were using auto.

If I knew where all the voltage measuring points were, I'd measure them!

I guess auto goes up probably as you overclock but at what point does the voltages get "too high" on auto?

From my personal experience auto always seemed a bit low for the settings I tried when overclocked so I'd always have to manually set it higher... then again it has been a while since I've used auto!

I do know that the ICH voltage stays at 1.057 when you leave it at auto and go higher on the fsb.

Eh, not really actually.

A bit cozy, yes, but when you up vcore, that's sorta what happens.

When i am running 1.45V (1.42V idle/1.4V load) on my systek, i get idle temps of 55C.

This does go to prove the auto settings do increase at least some of the voltages, as i believed.

I would appreciate if you could do some Orthos runs though.
If you can get a couple hours of Orthos blend w/o errors, it's extremely unlikely your system is unstable, regardless of what Memtest results are.

If you dislike using auto, you need to do some experimenting.

It sounds like you were not using enough voltage before, so now you merely have to start out somewhere with voltages & up them till things are stable.

This may take a few days of messing around with settings, but well, that's overclocking...

Keep in mind that with vdroop, what you set in the bios isn't what you're actually feeding the CPU.
Use PC Probe II & CPU-Z to check what it's showing as.
CPU-Z will show glitch around ~1.4V or higher & start showing very low vcore though, keep in mind.
Then you have to rely on PC Probe.

I was going to take your advice on trying the orthos testing to see if I am even stable. The temps just seemed too high so I didnt want to do anything before checking first.

Yeah the voltages seem a little whacky to me. I left everything at auto last night and just tried changing the voltage for the ram. As soon as I changed it from auto the system wouldnt pass memtest again. I started it off at 2.25 and got up to 2.4, none of them worked.

 

[loki5667]

Still have a lot of work ahead of me, but at least today was some progress.

First off I figured out that I can play with some of the voltage settings without issues.

I set the voltages to:

Memory Voltage...............auto
CPU VCore Voltage..........1.4375
FSB Termination Voltage...1.3
Northbridge VCore...........1.45
Southbridge VCore...........1.5
ICH Chipset Voltage.........auto

With that I ran about 5 hours orthos blend without any issues. I had also re-set my hsf so the temps were better.

Still have more testing (yeah I know 5 hours isn't that long) and I have to see what I can do still with the voltages.

What I REALLY don't understand is what's going on with the memory voltage. Yesterday night when I played around with it I got it up to 2.4v (started at 2.25v) and was still getting errors on memtest. Why does it seem like I can play with these other setting but mem voltage causes problems? Has me puzzled at the moment, but as long as it's stable with further testing I guess having it on auto isn't a big deal.

 

[loki5667]

Still confused over the issue with memory voltage??? I have now even been able to change the memory timings from 5-5-5-15-6-42 to 4-4-4-12-6-30

These are the setting I am using at the moment and so far they have passed orthos blend for a little under 6 hours. I'm just going to leave it running and then I'll run a different test like super pi to see what that has in store for me

You gotta figure out what vdimm your RAM is using.

Assuming your Super Talent is actually Micron (hard to say since they seem to have switched ICs around the time you ordered), you should be able to run around 4-4-3-X-4-30-4-10-4-10. (full timings set in order)


Those are quite tight sub timings though, so i wouldn't do that until you figure out wtf is going on with the RAM

X (TRAS) = 4 on many Team Xtreem & other brands' Micron dimms, but i'm not sure about Super Talent.
Once you figure out the voltage stuff, you could try lowering TRAS slowly from 12 down, but keep in mind, the difference is mainly only noticeable in Super PI

 

[loki5667]

ok so I guess the other night I wasnt using my head, never really thought about going under 2.25v for mem. Well 2.1v 4-4-3-12-6-10-10-10-10 passes.

That's very interesting.

So your RAM like lower voltage it seems.

Which would indicate it's not likely actually Micron, since Micron loves more voltage...

So you might not have gotten D9GMH...

Seems that anything over 2.15v and I get errors. Hmmm so if it isn't d9gmh is that going to limit the potential of my system? For the price of the ram is there something I should look into getting instead of this?

 

[n7]

Since you can still always loosen timings to 5-5-5, i wouldn't worry too much about it limiting you, as i am sure it will run 425 MHz (DDR2-850), which gets you 3.4 GHz.

You just won't likely be able to run it 4:5 (that would put it @ DDR2-1002.5 speeds if you are @ 7x401).

 

[n7]

I came across some more info on RAM subtimings for the P5B Deluxe.

Seems as if these are fixing alot of issues people were having with Corsair instability.

x-x-x-x-6-42-3-11-5-14

IOW, the default last four using 10-10-10-10 isn't ideal.

 

[loki5667]

One more quick ?

What kind of routine do some of you use to check if your OC is stable? Mainly want to see how many hours of orthos before you can say those settings are good.
Also with super pi, does that just run once & what kind of times are considered good?


I've got 425/850 running for about three hours now. Temps are sitting at about 55-56
It had completed super pi set on 32M but I wasn't sure if the times were good for not.

 

[rxblitzrx]

Awesome! Looks like you got another winner loki.

 

[n7]

I use Orthos blend for short sessions like 5 minutes till it starts erroring, & then i back down & run Orthos for a while longer.
That & the 3DMarks or just gaming

Oh, & remember this

[loki5667]

It's been running close to five hours on blend at these settings.

 

[loki5667]

So how do you think this looks? Ran orthos blend for over 10 hours and it also passed super pi 32m without throwing me any error messages.

I'll have to play more with memory timings and sub timings, but for now I just want to load up some games and enjoy this setup a little.

Memory voltage back on auto. I dunno but I remain stable using it. I know that anything over 2.15v gives me errors when testing, so I'm pretty sure the auto setting wont juice the ram up.

Also two more ?'s

What kind of super pi times are good? Just wanted to see where I stand with that.

Then what about temps? With this oc TAT shows temps topping out around 57-58 on both cores. Using the TAT test, they go up to around 65. I have re-applied as5 twice already and I'm pretty sure it's nothing I am doing wrong with the paste or the way I am installing the hsf. Do my temps seem too high? Sitting here just typing (close enough to idle) they are at around 45-47

Anyone run into any issues with their optical drives when oc'ing? Both of my drives show up but one of them doesn't want to read discs.

Also ran 3dmark05 and the score was a little over 11k. I have to dig around and see how that is compared to similar systems

 

[n7]

Everything seems good.

I don't know about optical drives not showing up, but you might wanna try the latest IDE drivers.
http://forums.anandtech.com/messageview.aspx?catid=29&threadid=1959001

They fixed some issues i was having with my optical drive.

 

[loki5667]

Yeah I'm wondering if the drive just died on me. Both optical drives show in the bios and show in windows, but the one drive just won't read any discs. I double checked what mode they are running in and both are udma 5

I'm just playing with the sub timings a little still. Have to pull the board and throw some AS5 on the southbridge & tape down the 40mm fan I got for it. Have a northbridge cooler on the way as well as a cooler for my video card.

n7- Thanks again for all your help! Has really gotten me up to speed on how these new boards work and your suggestions have really helped me get this rig stable
