Understanding VID and stock voltage??

[Mango1970]

Hey all,

Just a quick question. My VID for my new CPU os 1.175. When I actually set that in BIOS... my actual reading using CPU-ID is way lower. Now I oced my q9550 to 3.6 GHZ and left it at 1.175 in Bios and in CPUID it shows at time 1.144 and then 1.156. It has been stable for weeks playing the games I do and work I do. However when I did a prime run for a few hours I got an error. I am not sure if it was because of the 8 GB of RAM (4 sticks of 2 GB each -- what should I increase in my bios when you populate all the RAM slots??) or if it's the actual CPU.

I thus pumped the Vcore in my bios up to 1.2 which still shows only 1.168 im CPUID. It is now stable for over 4 hours. Should I actually have the BIOS vcore at an amount that will read 1.175 in CPUid in Windows? Or it does not matter?

You should read this anandtech article regarding voltage and your processor:

Specifically this page: http://www.anandtech.com/cpuch...howdoc.aspx?i=3184&p=5

All your questions about BIOS voltage versus reality are explained in those graphs.

Excellent page! +1 :thumbsup: That 2nd Graph says it all.

Thank you just got a chance to read that - can't believe I missed that article. Heck disabling Load line calibration worked wonders alone. Thanks.

load line calibration (referred to as LLC in the forums) is like a knife, it'll do bad things if used inproperly but can be very handy and useful when used properly for the right situation.

Sharp knifes make for bad pillows, and pillows make for bad meat cutters.

I use LLC and it helps me immensely for my situation, others not so much. Whether you meet someone who adores or villifies LLC kinda comes down to whether you are meeting someone who needed a pillow but kept using a knife, or needed a knife but kept using a pillow, versus a person who needed a knife and was thankful he found one in the kitchen drawer (BIOS) when he went there.
