TH7II Settings Advice

[Eggroll]

Hi,

I'm new around here, been lurking for a little while, so I'm just going to try and jump in.

It would be great if someone could tell me if I'm correct about two assumptions I'm making about this mod. First assumption, that the setup to do this mod is virtually identical to the one used to do the vrimm mod and, second assumption, that instead of soldering the ground wire to any empty mobo hole you can also attach it to a mobo, hd or cdrom screw just so long as it's grounded.

Also, for those of us who are soldering challenged, there is a guy who sells the vrimm mod setups already assembled with a 500K pot, the Pomona Grabber and a screw terminal for $10. Any reason I can't get two and use one for the vrimm mod and one for the vcore mod? 500K may be more than necessary, but the pot is apparently easy to adjust incrementally.

Any feedback would be greatly appreciated.

Thanks,
Eggroll

NO !! STOP RIGHT NOW !!

You don't want to solder pin 7 and pin 6 or 8 to each other at all... The ONLY pin that you solder is PIN 7 on the HIP-chip, and you only solder a wire to this #7 pin to connect to your pot.


You just solder a thin piece of insulated multi-strand wire to pin 7, then solder the other end to one of the legs on the pot.

Then, taking a seperate piece of wire, solder to another leg of the pot, as in the diagram, and connect the end of this piece of wire to ground.

Got it ?

I think jdmcnudgent must be kidding since he just drew the correct picture above. I'm guessing he's making a joke about a previous post that suggested he might not be ready to do this mod.

Geez, I hope you're right mate..

Otherwise he'll fry it for sure..

ok, im doing the mod right now, and im having a problem soddering the 7 pin and the pin next to it together. any tips?

Yes. If you are having a problem with soildering the pin next to it then my advise is get someone who knows how to do things like that and have them do it for you. It would be worth $10 to you for the guy to take 5 min and do it right than for you to take an hour and screw it up and end up with no chip or mobo.

i know how to sodder buddie. i am generally having a problem soddering the pin 7 to the wire. i know what i am doing, i am just having a hard time doing it. geez, you people, i am serious, i am asking serious questions about how to do this. i will wait till tomorrow till i can have a clear head and do this. i need advice seriously. thanks, and not thanks to the people that thought i was joking. i would not joke with a $171. mobo.

That's why I'm going to use a Pomona Grabber if I do the vmem volt mod to my TH7-II.

jdmcnudgent,

I'm not sure it's so far fetched to believe that someone would think you were joking when you said "im having a problem soddering the 7 pin and the pin next to it" when, as far as I know, that's not what you're trying to do. But I apologize if my interpretation hindered your ability to get your serious question answered here.

Peace,
Eggroll

To jdmcnudgent,

Take some painttape and tape the pins 1 t/m6 - 8 t/m10 this will give you a nice solder of pin 7

k fellas, here it is.

 

[jdmcnudgent]

thanks to all who helped me with this. i knew i could do it.

What have you got the CPU running at now with that vcore?

What have you got the CPU running at now with that vcore?

currently 2549. need some more help. got find a good trick to get the northbridge temps down first. second, i have the 39b bios, and i need to reflash to the 39c, is there a big diff? third, wondering what to set the ram at in the bios, and all that stuff. i would at least like to run the fsb at 150. any help would be greatly appreciated.

For cooling the Northbride I remove the heatsink unit on it and clean the tape they have on it then allply some ASII. I then get a fan from an old Pentium systum and fix it to the heatsink for the northbridge and hook then to the PSU. If you're wanting to hit 150mhz FSB with your system then go to the 39c as it gives more stability on the higher bus speeds. The RDRAM tho will probably need to be shifted to x3 rather than x4 as it's likely that the clock generator chips for the RDRAM won't hit 600mhz. Setting to 150x3=450mhz will give what you may think to be a slower setup in which it may by only a little.

 

[jdmcnudgent]

thanks for the help. but how do i get a boot disk with only command.com on it? or can i use two disks, boot to dos, and stick my other disk in with the flash on it and the bin? also, i have as3, if i lap right now, will it be safe to put back on right away and overclock? i heard something like 72 hrs till its not conductive or something.

 

[batboy]

If you format a floppy disk in Windows, there is a box you need to check for "system files" in order to make it "bootable". If you format the floppy disk in DOS, then use this command:

format a: /s

Yes, it is safe to use Arctic Silver and overclock right away. Some folks think that after 2 or 3 days, the thermal paste "breaks in" or "burns in" and allows a little better overclocking. I've sort of noticed that too, but the resulting improvements are usually fairly minor. I wouldn't worry much about it. I would make sure you have really good cooling if you plan on more overclocking and increasing voltage. An 80mm fan that is blowing across the RDRAM and DRCG chips helps memory and system cooling.

ok, suscessfully flashed to 39c. now, how do i exactly need to have all the mem settings in the bios? im at 2200 right now, and everytime i set the mem timings wrong in the bios, i hang at 26. also, what does anyone think about what i should have the v-core at to run at 150 fsb. i can tweak it alway up to about 2.1, but i really dont think i need it that high. thanks.

 

[gone_fishin]

Well, my 1.6A @ 150fsb runs most stable @ 1.76 actual vcore voltage. Each chip is different but I think your correct in assuming 2.1vcore is more than needed for this.

2.6 may not be enough really for the RDRAM to clock a little higher go to 2.7 to 2.8. I leave mine at 2.7 right now and clocks just fine. My PC800 will go over 533 with no problem at 133/533. Still hitting 150/600 is hard. That's the the problem of the memory but of the clocks. They are rated for only 400/800mhz. To puch them to 600/1200 would be getting a 50% increase in speed rating from them which is really hard.

As for the vcore at 2.1. You really won't see much help from that high of a vcore really. You'll find the peak to hit around 1.925 to 1.95. At 2.0v then it starts getting flakey even with good cooling and no higher OCing.

now the 2.6 and 2.7 you are talking about, are they for the rdram voltages? i did not do this mod yet, but if i have to i will. also, do i need the speed error enabled or disabled in the bios. also too, i need to know what the differential current should be set at:4x,6x,5x,or 7x. and does the spread spectrum modulated need to be enabled or disabled? now, along with the differential current, what does my RDRAM need to be set at in the bios, auto, 300 or 400. and one last thing, is it better to use fix pci, or use the divider accordingly? thanks all.
