Turion CPU upgrade - Sager 4750V (D470K) - Page 5

Stevew, was that a bios setting or through device manager? I got BSODs with Sager's 2.04 as well. It also got through a PassMark Performance test benchmark before the BSOD and scored 20 points lower than Eurocom's.

Eurocom gave an IRQL error while Sager's gave a page fault in an unpaged area.

I'm going to try a fresh install with Eurocom's bios over the weekend.

Thanks m. I appreciate your help. I'm glad some have successfully upgraded. It's looking like I won't be one unless I find the magic bios settings.

I've tried Eurocom's 2.04 and Sager's 2.04. They both cause BSODs alternating between IRQL not less than or equal too or Page fault in non paged area errors.

I've tried default settings, resetting configuration data, resetting the Serial Port and Parallel ports to auto, disableing and re-enabling them and nothing is working. It's not the OS or drivers. I get BSODs trying to reinstall Windows too. 4 attempts with different settings.

I'd love to use the Eurocom bios even without the chip upgrade simply because of the DMA 5.

If anyone could post the bios setting that are working it would be greatly appreciated.

Serial port A
Base I/o address
Interrupt

Parallel Port
Mode
Base I/O address
Interrupt
DMA channel...

and anthing else that may be pertinent.

TIA

Well, my ML-44 came in. I flashed to 2.04a, and then installed the CPU. I've had windows up long enough to reinstall the processor driver and setup RMClock. However, on most boots, Windows (XP SP2) will freeze shortly before or after I login. The CPU heatsink gets *extremely* hot.

Both the old and new cpus are bare cores (no heat spreader), I used AS5 on the install.

Ideas?

Thanks!

edit: put the old 3400+ Clawhammer back in, works flawlessly. What now?
Thanks!

Sounds like the heat sink isn't sitting on the processor correctly. Did you remove the cpu contact like MS did on his cpu cooler?

Edit - Ok that was someone else I guess. But it sounds like the heat sink isn't doing it's job. Like it's not transfering heat correctly. Make sure it's seated on the proc alright.

Do you have monitoring programs installed so you can monitor temps and perhaps more important processor voltages? What are they?

m, just wanted to say thanks for posting the bios settings. Those are what the 1.04 bios loads on my machine. Did your ram timings change? If so, when I try again over the weekend, I may be able to correct things with A64 Tweaker. On a lark I ran Prime 95 for 4 hours with no errors on the 1.02 bios. The 1.04 won't stay booted long enough to complete a test.

Ok, removed everything, cleaned it all up. Put AS5 on the cpu, set the heatsink on, pressed down, removed heatsink. Nice grey rectangle. Screwed it all down, fired it up. Same problem. heatsink above CPU is very warm, as are the heatpipes and the finned section. Still locking up. Don't get far enough along to run any temperature monitoring programs.

Grrrr!

Some Q's
should I remove the 3 strips of spacer material that are on the heat sink? (these are outside the core's contact area). I think they serve the same function as the circular spacer dots on desktop cpus.

Perhaps the BIOS is over-volting the CPU?

opened the bottom, propped up the laptop and pointed a 12" desk fan at it... still crashes booting windows. Linux will die occasionally, but generally survives a *lot* longer.

Edit:

Got it to run for a little while. Idling at 43 deg C (mobilemeter) when it puked and did a BSOD.

It's difficult to keep it running long enough to install any software, but I will give it a whirl.

The CPU fan doesn't run all that much, tho i can hear it kick up and down speed wise. Definately a LOT less than with the clawhammer core.

For grins and giggles, I fired up my Linux partition, and let it run one of the OpenGL screensavers to try and stress the system a little, it kept running until the battery ran out - go figure

Not sure what's up with the windows side. Can't be drivers, safe mode pukes pretty quick too.

My current plan of action:
1- Do memtest86 on her. I was getting an occasional error with windows explorer prior to all of this
2- slap in another hard drive and do a vanilla windows install

Is it possible I got a bad chip?

Thanks!
-Ken

memtest86 has been chugging along now for close to 2 hours (on AC power), no memory errors, no crashes.

gave windows a shot, BSOD right after logon.

Edit:
Well, trying a different Hard drive and new windows install didn't solve the problem. It's all very strange. We have a 2nd 4750 at work that took the upgrade no sweat. However, I have a new theory, My 4750 is old (like September 2004 old), I know there have been motherboard revisions, its possible that mine just cant do it. Anyway, I want to put the clawhammer back in, and flash down to the 1.04 BIOS and see if that works again.

Can someone send me the 4750 1.04 BIOS?
Thanks!

Ken,
why don't you use Bios 1.05 nstead of 1.04?

My first experiences up to today are similar to yours. Had a few BSOD myself with XP SP2 after I've updated to Eurocom's BIOS 2.04a - same CPU = Clawhammer 3.2, nothing else changed.
My 4750 isn't that old, just over a year, but I'm still running the old keyboard BIOS as discussed before.

After the thírd BIOS update in a row I didn't have BSOD anymore, but Prime95 stopped after the first self test, which wasn't the case before. I went back to Medion BIOS 1.05 for now which was okay with DMA5, and is reliable according Prime95.

My biggest surprise came when I noticed that I have RAM speed now at 200 MHz with the same old 1.05 BIOS as before, which was set to 166 MHz previously, for sure. I have 1 GB with 2 x 512 MB Apacer DIMMs.

Anyway, the 1.05 Eurocom BIOS is still on their website. If anybody wants the Medion 1.05 (=015) BIOS, I can forward this - I had been taken off their website a while ago. The Medion has two more options (WLAN = last state or off at boot AND touchpad on or off at boot) plus a diff. start up screen (showing only AMD64 without further info).

I will prob. do further testing with changes to par. / ser. port settings the next days ...
Do we already have sb running 2.04a on xp sp2 sucessfully with the orig. CPU? If yes, can we have results if it is okay with Prime95 (torture test, 2nd option from top=much heat), please?
Also - CPU voltage used for max speed and RAM config + speed.

Thanks for all the support here - Steve

Edit: my CPUz info attached

UPDATE:
A couple of days and a couple of reboots later I'm back running my mermory at 166 Mhz instead of the 200 shown above (same BIOS) - strange behaviour ...

I don't think it is an issue with SP2. I was getting BSODs with both the Sager and Eurocom 2.04 bios' while trying to do a fresh Windows install. I think Ken maybe on the right track about minor hardware revisions.

Anyone with an "old" 4750 get the Turion upgrade to work?

Hi there,

I read this thread with much interest--as I've been planning on doing just such an upgrade since news of the Turion chip came out. However, I too have had my 4750 since 2004 (?) and am worried that the upgrade might not work for me. Is there anyone that has succeeded with an older 4750? Also, is there anywhere I can look that would indicate how old mine is? Or revision numbers we can compare?

Thanks!

Abe

p.s. It occurs to me that I might be able to tell how well my 4750 would take the upgrade by flashing to the 2.04a BIOS and then benchmarking it. If it runs the benchmarks stabily then it'll probably take the new processor okay. It seems that those who failed to install the Turion chip successfully had problems with even just the 2.04 BIOS--or am I wrong?

I've posted my mainboard info (with the Medion BIOS) from CPUz on the previous post, pic # 3. It shows Rev. 01, but unless sb comes up with anything different, you have to look somewhere else.
Can anybody from Eurocom / Sager confirm where to look for the revision on the board (place of sticker etc.)?
