should I manually set cpu voltage?

Specs: Microsoft Windows XP Home Edition, 3.099 GHz / 2047 MB
I've upgraded my cpu to the one stated..(also had to flash the bios for it to be recognised, so while at it, will all that be ok?? No need to clear cmos etc is there?)

Anyway, main question...the athlon64 x2 6000 processor I've installed is the 89w version.

According to AMD, the voltage for this chip is 1.1 to 1.4 volts.

When I looked in the bios, the observed cpu voltage readings were anything between 1.43 & 1.49. SO I manually set the voltage from AUTO to 1.4

Now would this be a recommended thing to do?? Or should I change it back to auto?

Now for the boring background from which this came about...You don't need to read this to answer my query above tho.
Reason this came about was because my pc kept shutting down when burning dvd's. (as if someone cut the power). After buying a better psu,cpu,cooler etc with no joy, I discovered revisions of my mobo had a capacitor fault which caused people's pc's to shut down when burning dvd's!

Apart from RMA'ing it, workarounds were to drop from udma4 to udma2 (seems to work!)

Another workaround which some found helped was to set the voltage for their cpu. (not tested result out for myself yet). I think this was because the pc would shut down if the voltage reached 1.5 or something. Anyway....All this is another story.

TIA. Tas

vCore is listed at 1.35-1.4v. At stock speeds, I like to run the lowest vCore voltage possible for stable operation.

That said, it's not at all uncommon for vCore voltages to vary from idle to load; I've yet to see any motherboard that vCore did not vary a little. 5% should be the outside limits or about 1.35-1.45v for a 1.4 volt setting.

I imagine 1.4v is fine but if your motherboard needs to be RMA'd for a problem like this, get it done.

MSI has always seemed pretty good in the RMA department.

If it was my board & still under warranty, I would RMA it.

Tnx for the replies.. The Burning issue only developed a few months ago..(probably the said capacitor deteriorating).

Bought the pc pre-built by cyberpower just over two years ago so don't think I could get it exchanged now. (changing the voltage didn't solve the prob...dma2 it is then)

Re my other question...As said above, I've upgraded my cpu, updated the bios to the latest one so the cpu will be recognised...Should I clear cmos??

If I do clear cmos, will everything be recognised & set correctly when I (presumably have to) run the auto configuration/setup/defaults/optimised defaults/whatever in bios?

tnx again.

No need to bother with the CMOS clear...just get the RMA process started. MSI will guide you through it.

From the MSI website:

"The warranty period starts from the manufacture date. To determine the warranty entitlement for the product, the Customer must carefully verify the first four digits of the Products serial number. The first two-digit number represents the manufacture year and the subsequent two-digit number represents for the manufacture month.
For example:
"0312 234562" means its manufacture date is December, 2003
"0402 234562" means its manufacture date is February, 2004

Limited Warranty Period by Product

MSI Motherboards are warranted for 3 year limited warranty (Two (2) years Parts & Labor, and the third Year Parts ONLY, shipping and handling fee will be required)."

I think you have a good shot at getting it replaced:

OK tnx for your time & replies Skip & iam.

Was asking about the cmos thing in general where updating bios was concerned but went & done it anyway. (I survived)

Have also contacted MSI so have to sit back & wait now...tho don't know if it's worth the trouble dismantling the pc again & being without it for a while when I can just drop to udma 2. Will see what happens anyway..

tnx again..appreciated.

The whole process, for me, took about 3 weeks after MSI issued a RMA number. I live in California so shipping times were minimal.

Still, pretty good service when I consider the pooched bios or other damage (they wouldn't say what problem they found) was my fault. I was returned a new motherboard in full retail box.

Resetting the BIOS, then setting failsafe or even optimized defaults will never give the best performance. IMO, it's always best to manually configure the BIOS settings, IF you know what you're doing.

TNX again for responding...

Had a reply from MSI..warranty expired...(2 years..UK)

I noted down the bios settings before clearing cmos, loading optimised defaults. Not much change. (reverted my changes back is all it seems)

I had this pc pre-built by Cyberpower & would take a guess that they just bang the pc's together & also load optimised defaults...

Only thing I can think of doing (not a bios freak but know the very basics) is setting the RAM timings manually. As the bios is set to Auto I can't see what cl etc it's setting my RAM to. Will they be Auto detected properly or does a generic setting get applied?

Ripped the stickers (info) off the RAM when I installed heatsinks on them so ran PC wizard to get info.. cl etc 5 5 5 sounds about right..Tho I don't know if PC wizard is reporting the RAM specs OR if it's what the bios is setting the RAM at. (Altho PC wizard says the voltage for the RAM is 1.8 volts yet in bios it's set to 1.9 volts. (change this down?)

Gone off topic a bit here...glad of any more input tho :)

Edit...

It's ok just done a crash course & know the values (sdp) are read from a chip on memory modules. I guess by tweaking the bios you're talking about overclocking here & there?
