I bought E7200 and P5Q-E motherboard and I tried overclocking it a bit... I raised the FSB from 266 to 333 (3.16Ghz on cpu), but I also had to raise the voltage up to 1.25 so that the CPU was prime95...

I have it... running with 300MHz FSB at the moment and 3x HTT link... F3 BIOS
Winchester 3000+ @ 2700MHz 1.65V watercooled
2*512MB Twinmos @ 225MHz
and GF6200 @ 6600 550/780MHz

Good enough for...

Here is collection of all BIOSes for this board... betas and official releases... enjoy ;) link

edit:
damn stupid user... forgot to paste the link :>

I also have 480-U01 and I couldn't find any VRs when I disassembled this PSU...

I also took few pics of it... and there is no sign of any VRs... Could you please show me where is this VR located...

I'd go for Mac mini... this little thing rocks... 1.25 goes easiliy up to 1.5GHz... maybe even more with some volt modding or better CPU cooler...

I overclocked my G3 B&W 300MHz to 500MHz. Of course with voltmod and improved cooling. Without voltmod I was able to run it at 400MHz stable.
Voltage on CPU is now 2.4V (2.0V standard), and it is...

Tonic:

ESR is serial resistance of Elecrolytic condensator. You want to keep it as low as possible, because it worsens capacitors quality. Good capacitors have ESR around 10m[ohm], or less.
...

Of course there is no voltage fluctuation at 1.4V... And if you are measuring voltage on condensators pins measured voltage will be rock stable... on CPU pins there is completely diferent story :D
...

There are tons of diferent ferrite cores... The size is not the most important parameter. It is relative persistance of material wich counts the most... And it can range from 1 to few thousand... So...

This is not the P4 EE 3.46... Tis must be one of the new 2MB cache prescotts intel PR guy talked about last week when I was on press conferene... They will be released shortly after Win XP 64bit...

I have PQI DDR2 533 with default timings 5.0-4-4-12... it sucks... but if I set it to 266MHz (533) speed it id doing just fine with 3.0-3-3-8... but bandwith at those settings is still lower than...

And 25W full load power consumption :D

Just tested it... at SPD it also reports 4:3 ratio and 355MHz mem frequency...

Then I set it to 400MHz and then RAM:FSB was reported as 1:1 but only in memtest... so I went to windows and tested...

Oh... I just tought it should be higher... I was used of bandwiths around 6000MB/s on old 800MB/s FSB... and I was expecting a bit more.

I already have latest version of BIOS... so there is...

This is strange... I tried everything from 333, 400, 533, 666 and by SPD but CPU-Z always reports 4:3 FSB:RAM ratio... and 355MHz mem speed. I just dont get it... what bothers me most is low...

Another motherboard is not an option... This intels sample board is at the moment only motherboard based on 925XE chipset in whole Slovenia :D So no go...

I have another question...

Sandra...

I tried everything from 8 to 17... only 12 and 13 works... Even CPU-Z reads "13x (12x-13x)"

So no luck for me :(

But I managed to run it at 3740MHz... not much of an improvement, but it is...

Thanks Xassius for the tip. It works, but there are only two options for changing the multi. 12x and 13x... so no overclocking via the multis...

So I have a problem... overclocking the FSB goes...

I'm testing this bad monster:

And I wonder how to change CPU multiplier... I know that it was possible to change multipliers on those engineering...

Hey!

It is nice to see that you are interested in doing this mod. :D

About value of specific components. I don't belive that Abit would be willing to give out infos about that... and even if...

Ok... lets do it!

First you will need to get a few components. The easiest way to get them is to unsolder them from dead motherboard. What you need is one complete phase of CPU power supply unit...

Ups... I totlay forgot about this... :)

I will make it today.

I have no idea.... especialy inductors are big problem, because they are custom made for Abit and I don't know wich value are they... other parts could be bought, maybe HIP6601 would be a little bit...

Hello! Me again... :D Lets answer some questions...



It should... I think that AN7 uses sam voltage controler as NF7, so it I think this mod is possible. I also know it is possible to do it...

New pictures!

More capacitors added...

2*3300uF 6.3V, 2200uF 16V, 20* 5uF 6.3V:
