Abit TH7-II MOD gesucht, dass muss doch jemand wissen !

[TurricanM3]

Hallo,
suche einen VCore bzw. VMem Mode für mein Abit TH7-II, der RAMBUS-Speicher braucht unbedingt mehr Spannung (will stabil nicht auf 133MHz).
Ich habe schon verzweifelt mit google.de gesucht, bin aber nicht fündig geworden.
Es gibt so ein MOD auf jeden Fall, bloß wo???
Bitte helft mir!

re!

hab mal geschaut!

so wie die sache aussieht, iss es der gleiche mod wie fürs KR7A!

I am somewhat relunctant to try the Rambus road -- but the TH7II supposedly gets to 133 fsb pretty easily with some pretty sick memory bandwidth. And I hear that recent Samsung Rambus has been yielding chips capable of PC1066.

The limiting factor is that with a Northwood plugged in the board is limited to 1.625 Vcore (with a Willy chip it will go up to 2.2 Vcore -- the the board is capable, its just bios restricted).

I am leaning toward the SiS645 but ...

1. The Abit solution is not yet vailable, and I am a huge fanboy of Abit (the fixed PCI/AGP settings on the TH7II and BD7 is way awesome -- as is the BD7's four-phase power supply). Info on Abits SD7 is nowhere to be found.

2. Good PC2700 (like Corsair) is still way expensive (like $150 for 256MB -- I like to run 512MB).

BTW, I have now confirmed that the TH7II uses the exact same Hip chip as the KR7A and KG7. I wonder of the Vmem chip is the same??

I will ask this as well in the Intel Mobo section -- but I doubt they are hardcore enought to know.

I am setting up an Intel system for the first time since I started O/C'ing. I got a nice Northwood chip and an Abit TH7II-Raid board and 2x 256 MB of Samsung RDRAM (I got an amazing deal from a guy in desparate need of money to redo his hardwood floors).

OK, now the questions.

I have examined the board carefully and located the HIP6301CB chip (for Vcore mod) and HIP6521CB chip for Vmem mod. These are exactly the same chips as on my KR7A.

1. Currently the TH7II limits Northwoods to 1.625 Vcore (lame -- Willy chips can go up to 2.1 Vcore). I plan to use my pomona grabber mods to up that Vcore -- I don't see that there will be any problem assuming adequate cooling (in this case watercooling). Do you guys forsee any trouble??

2. I know that RDRAM can kind of suck in that it may limit an overclock. Nevertheless, I was thinking of doing Vmem mod -- will Rambus RAM respond to upping the voltage in the same way DDR does -- i.e., it is able to attain higher O/C? I have never heard of anyone overvolting Rambus and I here it can run hot at stock speed. Am I asking for trouble???

Thanks for any input.

At stock 1.5v the Northwood puts out about 40w of heat. I bet that at even 2.1v its putting out less that 100w -- which, as well all know is still well less than the current Palamino.

I will let you guys know how it goes.

Thanks for the input Doc.

I need to get my Vapo up and running. (Long Story: but I bought it from a kid for $400 (only paid $60 up front) and Fed-Ex busted up the case. But the cooling apparatus still works fine -- so, either Fed-Ex pays the insurance and I get a new Vapo, or I will keep the apparatus (pay maybe $40 more for it = $100 total), and put the apparatus in an Lian-Li PC71 -- now that would kick). Until I find out what happes, I am sticking with my watercooling solution.

Here is an update on my progress with the Northwood 2.2 and an Abit TH7II-R.

I rigged up the pomona grabber to the 7 pin on the Hip 6301. As we suspected lowering the resistance resulted in a raise of the Vcore. I set the bios to 1.4Vcore and booted into bios (amazing a 2.2 ghz chip @ 1.4Vcore.) I then upped the Vcore to 1.5Vcore actual. So far so good. I then set the bios to 1.3Vcore -- booted and PC Health screen showed 1.4Vcore. Not surprising. I slowly turned the pot and got back up to 1.5 Vcore -- this would amount to a 0.2 Vcore increase -- for 1.825 at max.

I then set bios to 1.2 Vcore, booted. PC Health showed 1.4Vcore. I turned the pot slowly and Bios froze. Damn!!

So backed it down and rebooted and got the annoying alarm. I had to clear Cmos to kill the alarm. After that everthing was fine -- no damage.

Now my question. The only other board I ever volt-modded was the Abit KR7A -- which used the same Voltage IC -- and only required a mod on the 7 pin. I understand that a mod was required on the 10 pin as well for the KG7 (again it uses the same mod chip).

I am wondering, did the KG7 do the same thing if you tried to take the voltage too high without doing the 10 pin mod?? If I do the 10 Pin mod -- how far to I turn the pot?? I will I know when I have turned it enough. (As I understand the 10 pin mod only increases the head room before the voltage regulator kicks in).

Let me know your thoughts. Thanks.

BTW, as I suspected, no one in the Intel forum is hardcore enough to actually try these mods -- no one has responded to my questions.

Thanks.

Update Doc,

Volt mod worked great on the Abit TH7II-R. I am now getting 1.6 Vcore with the bios set at 1.3 Vcore. That means at a setting for 1.625 Vcore (highest in bios for a Northwood) -- I will achieve a healthy 1.925 Vcore (should be plenty for a run at 3 ghz).

Right now I am waiting on my S478 holddown from DD so I can fit my Maze 2.1 to the board. (Right now I am using Cooler Master -- air cooling blows, literally).

Anyway, chalk up the Abit TH7II-R as one of the many fully modable boards (although you only really need to do it if you have a Northwood).

BTW, I think that modding the Pin 10 on the HIP chip is unnecessary. I did it -- but I never moved the pot. I appears that my process of dialing in the voltage was causing the lock-up.

Seems if you set the Bios to less than 1.3 Vcore the board will just lock and go into alarm mode. It seem the phenomena is totally independant of the voltage actually being pumped to the chip.

I am sitting here at 1.6 Vcore -- at 2.5 ghz fully stable through 18 hours of Prime. In fact I am running torture test while I type this message and listen to a U2 MP3 on Windows Media Player. No skips, no hangs, no errors.

I think I am going to like the dark side.

danke dir für deine mühe, ich habe den WIRE MOD gemacht, jetzt läuft mein 1,8er NW schon seit 3 Stunden Prime95 durch, wohlgemerkt auf 2,66GHz mit 1,8V. Die P4 sind echt der Hammer, bin gerade noch so einen XP2000 mit "AGOIA" Stepping am testen, scheint der letzte Müll zu sein, geht nicht einmal auf 2200+, auch nicht mit 2,1VCore, INTEL RULEZ !!!

Naja das mit müll kann man ja so nicht sagen...
und wenn "wir" mal gesagt haben "AMD rulez", haben "wir" immer zu hören gekriegt, dass das ja wohl ein niedriges niveau sei...
aber hast schon recht der NW ist ganz gut...
