Clevo BIOS Thread

Hivemind.

Flip a coin. I really don't know whats up with every Clevo user's HyperX kit on this forum. Logically, since this little problem is spanning across two totally different notebooks, the only conclusion I can make is that these batches these kits come from have high chance of fault, or that the user is extremely unlucky.

 

If you are talking about the M860TU with these HyperX, i think that the last BIOS 1.02.07 resolved the problem. See my post http://forum.notebookreview.com/showthread.php?p=5768824#post5768824
And if you have any solution for my problem, you are more than welcome to help me http://forum.notebookreview.com/showthread.php?t=454071

@maxibetta
The last firmwares for the M570U is quite old
BIOS : 2006/12/25 - 1.00.06 or 1.01.06(depend on you touchpad if it's Elantech or Synaptics)
EC/H8 : 1.00.06 - 2007/4/9
and you have also a VBIOS update for nVIDIA Geforce Go 7950GTX version 571223833 - 2007/5/3
and another VBIOS for nVIDIA G71M-Ultra version 571222612 - 2006/8/7 and another VBIOS for ATI cards which is dated 2006/7/31
So please enter your BIOS and tell me what do you have actually and what do you have as touchpad & graphic card

 

Thanks

CLEVO bios M570U
my bios update was on 2006 and i search for update

CLEVO M570U
INTETL MOBILE CORE 2 DUO T5600 1,83 Ghz
4 GB RAM DDR2 800
HDD WESTERN DIGITAL 500Gb
NVIDIA GeForce GO 7950 GTX 512Mb (CORE 575MHz MEMORY 700MHz)

 

So i need to know what touchpad you have Elantech or Synaptics?
And i'll send you also the VBIOS for the 7950GTX, you have to look in internet to download an application that load you GPU with the new VBIOS, (it seems to me that there were one for Windows user)

 

Well, this is weird.

When I was on 1.01.05, both modules had errors on slots 1 and 2. I tried to update to 1.01.05S and now both modules are error-free on slot 2 but had lots of errors on slot 1.

So I'm thinking that this has something to do with the BIOS revision, really. Like the guy above stated with the M860TU, the latest revision of their laptop's BIOS fixed the memtest errors.

What do you think SS?

 

I don't know. I've run several sessions of Prime95, Memtest, and Memtest86+ on my old HyperX kit that I sold here and on my own kit that I am using on my W870CU now. Both kits are flawless. The 1.00.05 BIOS on the W860CU should be identical to the 1.00.05 BIOS on the W870CU. I've had no errors before or after updating the BIOS.

 

Did you guys have the Hyper-X RAM installed by the laptop manufacturer or did you buy and install yourself?

 

Why would ask that? It's rare when a manufacturer offers them. I think most of us (including me) bought and installed them ourselves.

 

I'm wondering if the DIMMs have been validated in Clevo chassis. We had issues with a major brand SODIMM manufacturer similar to what is being described here, didn't cause us problems as we caught it early but not all laptop RAM works in all chassis.

 

Hi neil can you tell us if there are any SODimms we should aviod to install in M86 system?

 

The only ones that I know from first hand experience you should avoid are OCZ.

We use Corsair but have used Crucial and Patriot in the past with zero problems. I'm sure the stock Kingston SODIMMs would also be fine (i.e. non Hyper-X ones).

 

Almost all of Kingston's memory lineup (except for some of their server branded kits) use OEM Elpida chips, including the HyperX line. The datasheets for SODIMM value RAM and SODIMM HyperX RAM are identical with the exception of the firmware and the timings.

 

That may well be the issue then. I'm only hypothesizing about this but if you are seeing a higher than average failure rate then it makes sense that it is either down to 1/ a bad batch of SODIMMs/bad product or 2/ CAS5 or something else doesn't go down too well.

 

That is also the thought I have as well. The Clevo users here that have HyperX kits had to RMA their kits atleast once until they received a good kit, including myself; the DDR2 HyperX kit that I have in my Asus 1201N that I am typing on right now was faulty out of the box and I had to RMA it. The same thing can be seen in the Alienware forum. There are dozens of users that have had beef with the HyperX line. But it is also correlated with the fact that only Kingston produces some kits with latencies that low. It's a really a gamble in the end.

 

Yeah, thanks.

 

That is a factor to consider as well. The only way to test for a faulty slot is to use a regular stick of RAM.

 

Even just a 1066mhz stick of small capacity that will be used just for testing?

 

As long as you know that the stick is free of faults, you can use it.

 

Yeah, guess I have to do that.

 

Test everything first, then post your results.

 

Even if you have one free-error slot and other with error using the same RAM module, it doesn't mean necessarily that the fault is in the slot and not in the RAM. This subject is very complicated, it's a combination of RAM module, RAM controller and the BIOS that communicate with them.

For example the 1066 HyperX with M860TU chasis with BIOS 16, you can achieve no errors by editing the SPD info on EEPROM to CAS 6. but if you upgrade to BIOS 17 you can CAS 5 without problem

By the way i really don't recommend editing EEPROM, it could become irreversible suddenly as what happened with me and please if any one can help me in that problem i would be very thankfull http://forum.notebookreview.com/showthread.php?t=454071

 

Alright I will post my results after finishing the test.

Meanwhile, is it possible to downgrade the BIOS to the original one that came with it when I bought it from RJTech?

 

Corsair, Crucial and Patriot don't have CL5 modules.
Patriot and Kingston usually both use Elpida chips.
I guess the only CL5 memories that we can possibly get are indeed the HyperX.

 

Weird, I have those HyperX memory modules but why are mine running at 7-7-7-21? That's CAS7 right?

Part number is KHX1333C7S3K2/4G

 

hi pkhetan,
the KBC/EC version on my laptop is 1.00.02 so there is no update needed. But i noticed the BIOS release date difference. Mine is ver 1.01.04 and release date 2007/10/30. Please send me the BIOS file to:

janezjaniATyahooDOTcom

I will check for the differences in both files.
tnx

 

Yes, that is CAS7
What laptop do you have ?

 

A Clevo W860CU.

 

Then CL7 is what you should expect. Normal non-HyperX memories would work at CL9.

 

Oh ok.

Normally, you can see if the RAM is good if it passes OCCT CPU Linpack test or IBT right?

 

I use prime95 blend test.

 

So yeah, if it passes those test you probably won't see any errors if you run Memtest right?

 

Yes, 10 char.

 

Ok. So there isn't any new BIOS out yet for the Clevo W860CU?

 

.... solved

 

Surprisingly, I had exactly the same problems with my HyperX set and exactly at test 5 and 6 did the errors showed up. I had to RMA my Kit and got refunded. The kit was also giving errors in prime95.

Here is a thread I've started some time ago with my problem, I initially thought it was a bad motherboard: http://forum.notebookreview.com/showthread.php?t=442297

 

Weird, huh.

So this is not a motherboard or slot problem at all?

The HyperX specs are great but damn them if they perform below specs and as we all know we are limited by the BIOS of laptops to tweak the timings/speed of our RAM modules.

kevindd992002, I had in my memories W870CU Clevo 5-5-5-15 Kingston HyperX DDR3 1066 (4GB) and got the same problem as you, send my notebook to the RMA and explain what was happening to me and changed me a memoir by Kingston DDR3-1333 DDR3 (4GB), since I no longer have any problems.
I think the BIOS does not support W870CU Clevo While these reports and the first I buy the Clevo M570TU also had these memories and I had problems with them, and changed the W870CU Clevo notebook and the latter also had problems with Kingston HyperX until I replaced them by the Kingston DDR3-1333 DDR3 (4GB).
Tell the seller you can trade them for another model of memory.

 

Well, I have the DDR3 1333 4GB as you can tell in the product code I've wrote in my above post. So I still don't know what's the problem.

So the problem was not in your laptop? It was in the RAM modules themselves?

@all

Can Memtest86 3.5 and Memtest86+ 4.0 give false positives and false negatives in testing?

If I had a bad RAM, shouldn't I get errors in the same address consistently?

@Blacky

Is it safe to downgrade my BIOS?

 

I don't know if they can give false positives, when I had my errors they were all over the place and I know they were no false-positives.

You can downgrade the BIOS, I see no reason why this would create problems. Only downgrading the EC can create problems.

 

Does that mean when you had errors, they were not consistent at one exact address of each memory module?

 

I changed the memory for a normal 1333mhz Kingston, Kingston HyperX no longer have in my notebook and since I no longer have blue screen shot, but I have not stood the test of these new memories mentest Kingston since I have not had any problems with them.
Have you tried putting your memories on another computer to see if it fails?
or to other memory modules in your notebook and make a mentest?

 

Well, Kingston gave me a screenshot of their 24-hour and 48-hour test of these memory modules, before sending them out to me and they did not have errors, this was using Memtest86+ 4.0.

I just tested them again using Memtest86+ 4.0 as well and surprisingly I too had no errors, could this be a false positive or what?

I have yet to secure regular memory modules so that I can test my slots.

Soviet Sunrise, any suggestions?

 

Files sent to orkanbey, maxibetta and Laptop_user

 

I have nothing to say.

 

The new modules that kingston sent, do they have the same CL timings? because if kingston araise the timings, it's normal that you don't have errors any more.
