Na, bios 1.0 (for rev2) allows up o 250Mhz.

Btw, nice success stories here, love that

Oh

Think I got it wrong. My fault. It was the older revisions...
But last I changed to 1.0 I didn 't gain any oc over the 1.4, maybe the ram is maxed out.

Playing around I found out that one stick can go 244 easily at 3,16V the, other one only does 240 at the mo

Gonna try the 3rd stick of the batch when my friend visiting me soon

Waitin on my twinmos and rma'ed Corsair to get here. My max with the Corsair XMS3000 512 stick is only 205.

I flashed back to bios 10 (got several write errors, but it runs fine) and now Im able to use multi 10x and higher with high fsb

Currently im priming 242x10 and everythings is stable, going to test max mhz and fsb now, wish me luck

**xigfrid** · 07-25-2003, 12:26 PM

good luck mate :p

for my part , i 'm currently remaking my wartercooling setup , improving some airflow. here my 1st try with my 1700+ i was running at 2.2Ghz before ( 2.6 was unstable but so nice

)

Hmmm, i've the wire trick twice once connecting Ah30 to Ah28 and the other time AH30 to AH32 - is this correct because if it is then why does my cpu show up as 500 MHz cpu on the second time i bootup. Currently my 1700+ DLT3C 310 is running 230 but thats because of 1.9V vdd, i cant find any conducting pens so i have to do the wire trick. Plese help.

Look for the third picture Ragnarock posted here:

That's how i got it done with the wire trick. Gotta get a piece of telephone wire. The strands are hair thin, perfect for this mod. Gotta get a magnifying glass so you can see exactly what you're doin. With the 2100, it booted up as a 2700 which is a sign i did the mod right. Not sure about the 1700 tho.

**beo** · 07-25-2003, 07:13 PM

I flashed back to bios 16 cuz of the write errors and now Im able to use 240x10.5 again??

Anyways, its summer and to hot to run with high vcore, so Im sticking with 240x10.5 1.9V

Thanks for the help ppl

What mobo are you using? I'm thinking it's showing this because it was succesful but the mobo doesn't recognize an 11*166 chip so it's putting the slowest it has.

**Russak** · 07-26-2003, 06:57 AM

Im using NF7-S v2.0. I've tried Ragnorok's method as well and it booted as 100*5.0. It's a good chip will do 2.5 on air i don't see why it can't boot at 166 on default voltage, but just incase thats the problem how do i fix it?

**xigfrid** · 07-26-2003, 07:32 AM

NF7-S will always boot in safe mode (100Mhz) when a new cpu is inserted, then just set your fsb and multi , and save it-reboot

**Demonic** · 07-26-2003, 10:00 AM

I finally got my ass of the sofa and pulled the Alpha off my 1700.

I tried tying a loop of wire around the pins mentioned but my hands didn't seem to want to co-operate. So I made a loop of wire that I stripped from an old floppy ribbon cable and dropped it into the appropriate socket holes between the two pins shown in Ragnarok's picture, rebuilt and rebooted.

The BIOS was still showing the 220FSB that it had before the wire trick but it won't let me select anything other than "User Defined" in Softmenu III so I gather this has worked.

As for whether it has made any difference, I would get an error 16 hours into the Prime 95 torture test before the "mod". It did this several times. It has now completed 24 hours of the same test after the mod at the same FSB. I'll be upping the FSB again soon so I'll let you know how it goes.

Just thought I'd post this for those with thick fingers and no conductive pen. It's far easier to drop the wire in the socket holes. Just make sure that it isn't too long and lies flat against the socket so there is no chance of it bending and touching another pin.

Here's hoping for an FSB of 240+ but I'm not sure where the Corsair XMS3200 will crap out. Anyone got experiences of max FSB for this memory?

Can't thank you guys enough for sharing this info.

Seems you've done it. Welcome to Xtreme BTW

**Hydra** · 07-26-2003, 02:32 PM

I had Thoroughbred B 1700+ which I ran 11x200=2205 1.92v on my NF7-S rev1.2

Now I bought a Barton 2500+ which wouldn't do any more than 13x166=2172 1.62v, any higher on the actual MHz would cause prime95 errors or any higher on the bus would cause total hard lockups.

I just did the L12 mod to my mobo making the CPU a normal 133MHz FSB and now I'm doing 11.5x200=2305 1.81v flawlessy

Excellent

OK, i'm not a n00b... But I read almost all of this thread.... What the freak do i need to do? I have a 1700B that was downgraded from nothing. I have an Abit NF7 (non S) 2.0 and I get 225mhz (6-3-3-2.5) stable right now. Should I pin mod this? Should I cut connect the L12? There are so many people asking these questions and I am getting so aggriavated cuz I can't figure this out. Any help is appreciated. Please quote me when you respond also.

With a 133fsb cpu on a v2.0 you need to connect the L12.

**Russak** · 07-26-2003, 07:47 PM

I Guess i did the mod right, im guessing that it might be my vdd voltage. I just have a question, what vdd is everyone using to get 230FSB+ and what mode of cooling? I am using Thermaltake GF4 High Performance cooler ment for gpus attached by 1:1 ratio of AS3 and Alumina Epoxy. I did the vdd mod via the pencil trick so im getting around 1.8-1.9V. I think the cooling should be enough for 1.9V vdd what do you think? Russak

**Russak** · 07-27-2003, 07:48 AM

Does anyone know how to increase my default vcore on my DLT3C to something like 1.6V? I think that is the reason most of 1700+ DLT3C are not working.

So just painting those two pins is all that I have to do?

And I don't have to touch the L3 or the L12 bridges what so ever?

No. The L3 bridge has nothing to do with it, that is for multipliers. Painting those 2 pins is the same as connecting the L12 bridge on the top of the cpu, it's just easier to do.

**DriveEuro** · 07-27-2003, 10:03 AM

And there is nothing that I have to cut? Just simply paint the pins? Man, the people up earlier in the thread were talking of the L3 and cutting something on the L12 and painting the pins.......... BLAH!

**MrLavender** · 07-27-2003, 10:08 AM

There are different mods depending on your cpu type and mobo version, what exactly you want to do, and different methods of achieving the same effect. What I have decribed is the EASY way to do the required mod to increase fsb for YOUR cpu+mobo combo.

You can either paint the pin OR connect he 3rd L12 bridge (hence the L12 mod title

)

Awesome. Thanks. I finally can do this!!!!!!!! YAY!!!!!!! Thanks guys.
