Help me make my ram stable:)

Hello,

I'm overclocking my FSB. Long story short, my ram is unstable.

I can't flash this ram with SPDtool or thaiphoon burner because it's eeprom has write protection enabled.

It's 800mhz ram, which downclocks to 667mhz in my system (santa rosa chipset).
then I overclock my FSB and the ram goes to 900mhz with 667mhz timmings.

Around 900mhz the ram is unstable. Right now I don't want to buy new ram in hopes of it not being write protected.

So I somehow need to make this ram more stable.

First I would like any cooling suggetions for the ram.
What the best way to do it?
I'm guessing some copper sheets?

And second, more importantly can I "burn in" the ram?
Is it possible that if I run it at the point where it is barely stable for a long time on a hot day, the ram will become more stable.

Or can I just increase the frequency by 1mhz every day and hope that the ram will get trained?

I know what I'm saying sound stupid, but I really just want 50mhz more.

There must be something I can do.

Any help would be great

 

'trained'??

 

yeah, trained.

trained to be stable over time.

 

you can't train ram... it's not a dog. the only way your getting it stable is to buy some new stuff. DDR2 is cheap anyway...

 

why not sacrifice a goat over your keyboard, that old belief system is just as valid as the ones you are trying to apply to pc hardware.

EDIT: @newsposter, do me a favor and stop crapping all over every one of my posts.
you're not helpfull, you never post any usefull info, you just make lame jokes.
you are a troll!

If you continue to do this I will do it back to you!

 

Agreed. It's immoral and hazardous to crap all over moral hazard's morally hazardless posts. The KGB is watching you, newsposter.

 

people wouldn't be taking shots at you if you didn't make such an appealing and long-lasting target.....

But I'm sure you're right. Even though you've found no one here to verify your 'info' or offer proof that anything you want to do is other than (dangerous) folly, I'm sure that you are right.

 

shut up newposter... all ur post are taking potshots at ppl but every post of moral's has helped man ppl... just shut up and back off man..............

 

thanks soviet and sean

I decided that I have nothing to lose so I will try it.

Here is the status now:

257.7mhz FSB.

rated FSB = 1030.8mhz

ram 429.5mhz (859mhz) I get an error from ORTHOS after running for 35 seconds with large, in-place FFTs.

This is with both my sticks of ram installed.
I can get one of them to around 900mhz, but the other one is not as good.
That is why you see the error @859mhz.

Timmings were 5-5-5-15.


Here is the current max when I raise the timmings to 5-6-6-18 (I can't change the main CAS latency):

259.54mhz fsb
rated FSB = 1038.18mhz

ram 432.6mhz (865.2). I get the error after 5 secs with the blend setting.

My temp tops out just under 80C
which is pretty good.

I have attached a screenshot to this post. Also here is the cpuz validation:
http://valid.canardpc.com/show_oc.php?id=712238

Now I will stress my ram while it's overclocked to the point where it is barely stable.

After a few hours I'll give an update.

 

It would help if you told us what kind of memory you were running (I assumed DDR2 since it's Santa Rosa). Not everyone knows exactly which type of memor goes with specific Notebook Models, so post as much of your spec information as possible so that we can help your cause.

Your best possible solution is actually replacing the ram with timings that are a little looser since majority of Notebooks can't change memory timings through the BIOS settings. 5-5-5-15 and 5-6-6-18 are considered as tighter timings on DDR2 SODIMMs (now that depends on if it's DDR2 or DDR3), so I suggest some memory that have timings that have at least 6 CAS timing at your rated 1066Mhz FSB which you require.

However, since it's a notebook, you might not be able to get it stable at that speed. Especially a T7300, your getting a 600Mhz overclock and since your Multiplier is 10X (which is relatively low) you're already pushing the limits of the Santa Rosa chipset when it comes to memory stability. You're better off upgrading your processor to something else to attempt a larger "overclock".

My previous F8SN(Santa Rosa) was able to push a X9000 from 2.8Ghz to 3.2 Ghz, so your ratio is already much higher than what I was able to achieve. Of course I was on the other end of the spectrum and the CPU was the limiting factor and not the RAM, my suggestion is to get a T8300 and go from there to get a better overclock.

 

well, in my last post I gave a link to the cpuz validation which has a lot of info on it. But since you asked I will give you the details

I have two 2gb sticks of DDR2 PC2-6400 800mhz samsung ram.
The ram downclocks in my system to 667mhz with 5-5-5-15 timmings.
The voltage is 1.8V.
One of the sticks is stable enough for me, but the other is not.

My notebook is a toshiba tecra a9, PM965 chipset with the x3100 GPU.
The CPU is a T7300 (2ghz stock, 200mhz real FSB, 4mb L2 cache). The voltage of the CPU when I boot up is 1.238V (I can't raise it any higher with software or any other way except for a CPU pin mod, which I am considering to get past 3ghz).
I have done some tests and my CPU can go above 2.72ghz at that voltage.
It's a merom (socket P) CPU, 65nm.

My max temp right now @2.6ghz (using the stable stick of ram) is 83C.
I'm happy anywhere up to 90C, TJmax is 100C for this CPU.
There is no throttling in the ACPI code in the registry.
I will also do a cooling mod when I find the right fan at the right price.
For now I just clean out the dust and change the thermal paste every two months.

currently there is some cheap coolermaster HTK-002 paste on the CPU and the GPU/northbridge.

My southbridge has no heatsink.
My ram has no fan or heatsink of any kind. But my notebook has a lot of holes in the bottom of it.

I am waiting for the T9500s to go down in price, so that I could get to at least 3.5ghz.

T9500 @3.9ghz cpuz validation:
http://valid.canardpc.com/show_oc.php?id=647836

That ^^ is why I want the T9500.

Ofcoarse my problem is my ram.
When I get the T9500 I will buy new ram and flash it to a lower frequency and higher timmings.

Right now I just want a few more mhz on my current ram.
Could it be possible that cooling would make it at least a few more mhz better?

If someone can confirm that I can gain mhz with cooling I will start my ram cooling mod tommorow.
So is cooling the answer?

 

I'm willing to help you with this. Let's work on this together. Tell me what you want me to run and give me a couple specs and I'll give you my feedback in return. My system is very similar to yours, slightly different. You get a second point of view on your project. Your Intel drivers may not be up to the latest version, mine are. I don't know if that makes a difference.

Here are the specs I'm working with.

 

thanks.

I do have a few questions for you:
1. can you overclock your FSB (or are you willing to try with setfsb)?
2. Do you know if your OCZ ram has write protection enabled or not?
would you be willing to run SPDtool and try to just raise your primary cas latency?

There is a warning, SPDtool is something to be a bit carefull with.

I did brick a stick of ram with it.

Also my intel drivers are up to date, I have also tried win7 drivers on my vista installation. and also I tried some modified drivers.

I don't plan on gamming on the X3100, I'm going to use an external 4670 desktop graphics card through my miniPCIe port.

you could actually do the same.


EDIT: one more thing, have you tried undervolting? if you have, what volts did you get?

EDIT#2: my volts and temps:

FSB | multi | freq |___| volt | ________|temp| fan speed (out of 1 2 3 4 5)|
(100.0 * 6), 600mhz, 0.8500V, max temp = 36C (fan speed 1)

*the red values show where I tried to make a frequency by lowering the FSB, but it caused stange temps

All temps are maximum temps.

 

Absolutely... my laptop runs cool... and I'm not worried about losing it I don't know why you are. I understand what I'm in for and I signed up for it. I'm interested in this as well that's why I replied.

1) Yes
2) We'll find out
3) Yes

I don't think undervolting has anything to do with what you're trying to achieve. Or is that a preference?

 

Okay I'll start off with setFSB and SPD tool.

 

I was just interested to see how well your T7500 handles voltage. Sort of to compare my T7300 with a T7500.
But yes, it's nothing I can't live without.

If you want to see a background to how I'm overclocking, see my thread here:
http://forum.notebookreview.com/showthread.php?t=393027

Can you tell me how you're doing it (software or hardware method)?

Here are spdtool and Thaiphoon Burner.

Have you already flashed your ram?

EDIT: sorry didn't see your last post, so now my post doesn't make sence.

SPDtool is my fav, because it works well and shows what the problem is when there is an error.
Thaiphoon burner is what I killed my ram with, it's a bit hard to use because it gives too many options for me.
I got carried away...

 

It seems like you are pushing the memory outside of its running parameters.
What is the exact memory cell model and manufacturer?

If you need to, you can try getting more out of your processor by changing the memory to cpu clock ratio.

Have you ever experimented with BAR_EDIT?

K-TRON

 

moral hazard, you might have mentioned it and I missed it, but what are you OCing with? Modded BIOS or software like SetFSB?

 

it's setfsb.
I had to do a little mod to my motherboard and it took a few emails with to abo (creator of setfsb).

Now i wan't to do another mod to my motherboard to make my FSB 266mhz without the need for software.
But for this I need stable ram...

check the thread in my sig for details.

 

I started off with spdtool also. what do you want me to write and in what module. There's module 0, 2 or 7.

 

I'll have to get back to you on that one.

I have, but for other reasons.
please tell me a little more info on that, I think you just solved my prob

 

I don't understand why there are three?

Can you first try just increasing the primary cas latency by one?

EDIT: I mean change the primary cas latency (CL) from 5 to 6.

 

Give me a shortcut please... go here and do this.

 

ok let me download the program again.

It will take a min.

 

I used bar edit to change the northbridge to memory clock ratio on my workstation. Its very complicated and I wasnt too successful. I had to ask a computer science guy to help, since its all in hexadecimal, which I do not understand.

If you cant find the download, I can send it to you
email me:
[email protected]

K-TRON

 

0 and 2 are the memory modules.... module 7 is weird.

 

I have uploaded screenshots.
make sure you fix the checksum as shown in the screenshots.

BTW I have to go now, I will be back tommorrow.

you only have to flash one of the sticks for both of them to run at the new SPD.

 

I have reg-edit installed. I aslo know someone who is very good with it. You have done enough. thankyou

I have copied your email so you can delete it if you want.

 

Your opening up a can of worms by overclocking your laptop...but hey, if you don't care, go for it.

Also, your "training RAM" theory generated many lolz here in my class.

 

I'm familiar with hexdecimals. I don't need a calculator to add or substract two hex values. So how do I increase the CAS latency?

 

@ Twiz57, did you see my last post here:
http://forum.notebookreview.com/showpost.php?p=5317569&postcount=28

Look at what my mouse is pointing at in the sceenshots.
That's how to do it with SPDtool.

 

I have no idea actually, it is probably made by samsung.
This is what it has on it:
SEC 907 HCF7
K4 T1G08400

Looks like all I can do with BAR-EDIT is make the ratio worse.

 

I'm going to try to flash my 2 spare sticks of 512Mb (Hynix) instead of the OCZ first, but I don't think'll help with anything in my case. I need two sticks of PC2-6400 like yours to achieve what you're trying to do. Both of my memory sets Hynix and OCZ are PC2-5300. I think I'll be more succesful trying to overclock the CPU and find a way to cool it better. I'm looking for a set of pc2-6400... oh and yes I noticed your last post and I'm starting to get familiar with SPD. It's the right tool for the job but my material is too cheap.

 

One more thing... remember I said there's module 0, 2 and 7 ? Well it looks like module 7 is a BIOS mirror. It probably mirrored the ROM code into RAM to improve performance.

 

thanks for explaining module 7

Have you tried setfsb before?
Because if it doesn't work, I can help you make it work.
Although it might involve a small mod to your PLL (clock generator).

 

I'll try SetFSB, I'm more concerned about other ways to cool off the CPU and the GL960 (or GM965, it actually says GL960 on it, I looked). They're both on the same heatpipe. I'll monitor the temperature of course. I hear there's a world record on T7500 of 3.2 GHz.

 

I'm very interested in how your T7500 overclocks.
I bet you will get to 3ghz (if your ram holds up).

You may have to use RMclock to set your voltage higher.

Too bad you have the heatpipe prob

 

Here's that article, true or not, it makes you think http://www.ripping.org/database.php?cpuid=641

 

off topic, don't you think ripping.org should get some better servers.
It takes way too long to load their pages.

But they do have a great site.

Too bad that the 3.2ghz wasn't validated.
only 3ghz validation:
http://valid.canardpc.com/show_oc.php?id=508212

 

off topic, Yes. I got in once when I posted the link. Then it said server too busy overloaded. They probably run the server off of dial-up.

 

also a lot of users on this forum hold world records on that site.
Personally I have the WR for the T7300 @2.8ghz.

 

2.8 GHz is impressive. Congrats! I'm guessing that's with the original factory fan running at full rpm and the CPU has it's own heatpipe not like mine. Anyways back to SetFSB I'll definitely have to try it, what's the latest version you're aware of?

 

yes

You definatly want to download from the homepage:
http://www13.plala.or.jp/setfsb/

Abo (creator of setfsb) updates every week or so.

I have emailed him many times. If setfsb doesn't work for you then you may also need to send a quick email.
He replies pretty quickly. But also let me know what prob you have, I can help too.
Better tell me about the prob so I can help before emailing because abo doesn't like to waste time (lots of people get "I don't support you" from him.

 

Sounds good. Thank you sir!

 

Sadly SetFSB does not support my laptop... here's a capture of the PLL diags.

 

@Twiz57
Does PLL Diagnosis actually do anything useful anyway? I don't think so. Just search the PLL yourself.

 

We can make it become supported.
My PLL was initially not supported, but after I sent a few emails (and a small HW mod), it works.

I can see from your PLL registers in the screenshot that TME seems enabled (would need to check the datasheet to confirm this).
This means you too would need to modify the clock genorator as I did in the thread in my sig.

If you want to go further with this, the first step is to open up your notebook and find the PLL (clock genorator).

Yes it does.
It lets you see the PLL registers, so that you will know if TME is enabled or not. TME enabled means no overclocking without a small HW mod.

 

No problem... I can open up my laptop... and I have a 25W soldering iron ready. I'll update your thread with a few pics once I'm inside and I located the chip. Thank you very much for your support, I greatly appreciate it!

 

I dont know if your notebook will have enough space but have you tried copper ram sinks?
