I can only guess. I know that firmware can be reflashed, I can get dumps but anyway I'm not good with assembler and firmware internals

Re: highest p3 clock speed?
I agree.
Also, Willamate arch is even worst then Nothwood. Especially if it is a Celeron with 128 kb cache.
You can google that Core/Conroe arch is based on a Tualatin, not northwood/willamate. We all know how much better Core against P4.
Northwood is developed in right time to easily increase GHz marketing numbers so they perceived much faster than AMDs. Also remember massive Pentium 4 advertising. Intel want make money with less effort in that days and they made it....Leave a comment:

Re: MacBook Air 2010 RAM upgrage
Hi guys. I haven't receieved reply here for long time so decided that nobody interested
You're right, actually biggest issue is SPD. I can't find it. There is no ROM chips on motherboard that looks like SPD.
Furthermore, I think that SPD doesn't exist in MBA at all. Reasons:
1) memory is soldered = no way to change it, so no need SPD
2) I've run Thaiphoon Burner, it works on MBP with replaceable memory. On my MBA it doesn't "see" SPD.
So memory information is stored somewhere in firmware (EFI?)...Leave a comment:

MacBook Air 2010 RAM upgrage
Hello, guys.
As you know, RAM in MBA is not upgradeable, because it is soldered to mainboard.
My idea is to resolder memory chips. There are 16 chips on main board and general so-dimm module also have 16 chips. So I want to replace chips on mainboard by chips from module I will buy. I can do it.
The questions are:
Where is SPD?
Do I need to reflash SPD or memory amount is autodected?
Officially A1370 supports 2GB or 4GB of RAM. If I take 8GB in 16 chips, will it "see" it? I really interested in putting 8GB in it
Thank... -
Re: Using transistor as a relay.
Much simpler idea:
As FET you can use: IRF5305, IRF4905, IRF5210, IRF9Z24, IRF9Z34.. or just about any P-Channel MOSFET in TO220 case(because you need very small current). TO220 for easy air-wiring and you can screw it to something.
You can reduce R1 and R2 if you want... just need to R1/R2 = 10/1...Last edited by Gordon01; 08-18-2011, 04:19 AM.Leave a comment:

Re: LED lamps a bit lit when switched off
It doesn't matters.
Yes! Even small current thru LED is enough to charge CFL's cap.
Probable the same problem with LED lamps.
The switch must be real mechanical naked switch: without pilot LEDs or something...Leave a comment:

Re: USB not working on Asus P4C800-E Deluxe
What resistance datalines have to ground?
And once more: very common problem with ICH5, you can't fix that. Thanks god, that mainboard at least starts

Re: Motherboard not turning on.
Please check the battery voltage(with and without PSU) level and simple logic(74xx) around front panel connector.
Then: replace 32768 quartz, of no result - replace SuperIOLeave a comment:

Re: Samsung 245BW - Flip the panel output?
If processor's firmware doesn't support hardware flip, probable the only way is to add some electronic between panel and processor in the split of LVDS.Leave a comment:
