13X and higher bios setting?

[rogue1979]

I currently have a Abit KG7 motherboard running an AGOIA 1600+ @ 1800MHz. I have a 1700+ t-bred "B" on the way. Abit's latest KG7 bios supports the t-bred core. I can run 12.5X x 160MHz fsb to get 2000MHz. What kind of multiplier will the 13X and higher setting give me? My thinking is if I am lucky and my cpu hits 2100-2200MHz, that I will have to cut a few L3 bridges and hard mod the cpu to 13, 13.5 or 14X. Is this what the 13X and higher setting is for? Or should I just put the multiplier on default and let the hard mod do it's job?

Listen to johncar, he definetly knows what he is talking about.

rougue1979, if you use 13x and higher multiplier setting and your cpu is unlocked, you will not get 13x (or anything that you want most likely). Honestly I think it is unpredictable as what you will get. IF you do hard mod your cpu (I suggest you do if you want highest possible OC), then just set the BIOS setting to default.

Also, when you cut L3 L4 or L10 bridges if you hard mod, then use a 9v battery instead of physically "cutting." Just get some kind of lead small enough to touch the gold leads on the opposite sides of the bridge, and hook them up to a 9v battery. You will see a smally spark possibly, this will tell you that it worked. Also check resistance with an ohmeter to be sure. This is a much quicker, and much safer way to open bridges up.

By the way johncar, I am loving my new Athlon XP 2200+ (formerly 1900+).

Thanks for the link, can't say that I really understand it all, but it is a good place to start.

Another thanks for the linkage and info. Here's another link that I found, offering similar info.

Bump for another KG7 user

KG7's are awesome. People call them out dated technology, but the 761 chipset is the best ever for compatibility and trouble free operation. This Abit version is much faster than the other 761's. At a 160MHz fsb speed my memory performance is better than my MSI 745 Ultra (SiS) at 175MHz! So I am in no hurry to upgrade yet. Another bonus is Abit's unmatched support for older motherboards. I just put in a Radeon 9700 Pro, and I had a boot up problem that would cause me to use the restart button once to get a good boot. I go to Abit's support, and sure enough, the latest bios fixes the exact issue I was having. Everything is peachy again.

rogue, good to hear you got your warm reset problem fixed. I'm still dealing with mine even after flashing to the CT BIOS last week. I've had it since I bought the board and the ONLY way I can get it to restart is by setting defaults in the BIOS, meaning my 1600+ runs on a 100 FSB. Thats not gonna cut the mustard. I've tried at least 6 suggestions and can link you to three threads that I was involved in where no one was able to fix the issue. There are several KG7 owners who have the problem still. I even dredged the Abit NGs for info but found it remained unsolved there too. Most point to the PS as the culprit but mines been tested and runs fine as well as an Antec 300 unit I tried. No luck yet.

 

[rogue1979]

Wow, I didn't know about these problems. I now have three KG7's running and none of them have this problem, except when I put the Radeon 9700 Pro in, but that's fixed now. Maybe your board is faulty?

 

[rogue1979]

Update: Well, I cut the bridges with mixed results. Ended up with some weird multiplier combinations. I tried filling the bridges and reconnecting with defogger. What I ended up with was a cpu locked at 15X. Seeing how it runs 2100MHz at 1.78v that works out fine for a KG7. 140 x 15 and running cool and fast. I gave it to my son and I will get another one, heck they only costs $53. Right now I relocked my AGOIA 1600+ at 10.5X mulitplier and fired up an old 745 Ultra. Running 10.5 x 172 now for 1806MHz. I tried a couple of these MSI boards a few months back with Win98SE with disastrous results. Since then I have switched over to 2000 Pro. The 745 Ultra is running absolutely glitch free, I can't believe the OS made the difference. I figure the new one can run the stock multiplier of 11 x 180-185MHz, for an easy 2GHz+, probably at stock voltage.

hey rogue, howza bout being daring and trying a 2400+ on that KG7 ? I think it's do-able after reading some encouraging posts on other forums but its definitely not (usually) plug and boot simple.

 

[rogue1979]

I'll try when the price drops some. Right now 2100Mhz on air at safe voltages for $53 is hard to justify buying anything costing more.

thanks for making that website johncar
there's already been like 4 of these questions heh

Soulkeeper,
And Workarounds page would only be speculation, no matter how reasonable, without experimentation by people like you.

Please! please don't cut anything on your CPU, if you just want 13X on your XP1700!!!!!!!!!!!!!!!

Just follow the pic from this website.

I have tried it myself and it works!!! except I'd rather have my CPU running @ 180X12 than 166X133

 

[Doh!]

The only thing I understood from that linked page was johncar's website link.

Edit: Upon more careful observation, am I correct to assume that connecting AJ27 and AN27 pins to vcc pins does the trick? (scratching my head)
