Abit IC7 with 3.0v DDR ?

[Petrus]

After seeing the bios screen of the IC7-G bios at the Geil's USA site showing a 3.0v VDDR, I played a litlle with Modbin and modified the IC7_11 bios DDR voltage to 3.0V. I don’t know if it works as my mobo didn’t arrive yet.

How about passing it my way.. I'm willing to give it a go possibly

[Petrus]

OK I will upload it right away. Give me 5 minutes to post the link

[Petrus]

here it is let's hope it works

Ok, will check it out and see what I can come up with....

[Gamer67]

Ok, the settings do show up in bios, but unfortunatly they do not work

Selecting 2.9v or 3.0v defaults to 2.52/54v


bummer

[Petrus]

That's bad news My "old" ITMax2 V.2 did the same when selecting 3.0v. Thanks anyway for giving it a try

[Pedro Rocha]

To bad, 3.0v in VMem may help a lot, at least help in IT7, maybe the I875P don't need some extra v-mem.
I will use 2 Corsair 512MB 3500c2 XMS with my IC-7..


Gamer67 Could you please post one picture of your Prometeia mounted with the IC7-G.

I'm gonna mount mine in a few days, and like to know what can be the best tube position..

Thank you

[Gamer67]

I can try, pic might not be that good.... will do now

[Gamer67]

ok here ya go....


Sorry about the size...

[Pedro Rocha]

Thank you helps a lot !!!

I see you use the sames memory I use - Corsair 3500XMS

[Gamer67]

I use the XMS3500 in another system and I also have some XMS3200 in yet another, but the stuff in the Abit is TwinX3200LL (2x512mb)

omfg.. thats the pimpest setup ever.

does the chipset fan make that much noise? heard it was kinda loud.

[macci]

Well luckily the Vmem mod for IC7 ain't that difficult to do

[Xenogias]

Macci, got a link to it? or maybe a couple simple instructions? How much can you get 3.3v?

Thats a relief. On the IT7 series the mod was easy as hell, but you could turn it wherever you like it never went past 3 volts lol. Had something to do with other components on the board....

I've done the 8RDA Vddr mod (cutting trace and soldering to it) and the NF7 Vddr (soldering off tiny component then solder 2 wires to empty places) so if this is any easier , it'll be a welcome change

[macci]

the NF7 Vddr (soldering off tiny component then solder 2 wires to empty places)

Sorry but it seems that it ain't going to be any easier than this

Here is how I've done it:
1) locate Winbond W83303D (or 0?) chip near the IDE2 and DIMM slots.
2) locate R50 0ohm SMD resistor (on the right side of the Winbond chip)
3) solder the R50 off the mobo
4) replace w/ 100-1000 Ohms. (Im personally using a 1kOhm VR)
100 Ohms will boost it from 2.6 to 2.66V
So the higher the resistance the higher the voltage. So set the VR to 0 Ohms when you install it then slowly turn up the resistance until you reach the desired voltage level.

btw, it made my HyperX3000 fly

Thanks for that my friend. sounds basically like a combination of the 8RDA and NF7 mod hehe... that one also starts off with 0 Ohms, tricking the voltage reading so the controller compensates by giving some more.

One question though, are we tricking the voltage reading or not? In other words, can we look at the BIOS reading and see the Vddr go up? This would also mean if we add some resistance there, we can still use the settings in the BIOS to go up and down, unlike with the 8RDA.... I dont like measuring Vddr with a multimeter

excellent memory speed as well
I think my Twinmos can do at least 250 @ 3.0 volts. 3.2-3.3 Vddr should get me between 250 and 260 somewhere ... hopefully close to 260

[macci]

yes I can monitor the Vmem from the BIOS and MBM

[JCviggen]

Ok good.

so basically its the NF7 mod. replacing resistor with higher value

[Hiwayman]

Time to get out the soldering iron, and if you may want to sell or something you can keep the 0 ohm smd and replace it (if yer carefull) or use a wire bridge but don't leave it off, vddr will go skyhigh.

Nice that the correct Vddr can be seen using mbm and bios monitors.

Thanx Macci

[Yozza]

What will the voltage increase be when using a 1k Ohm fixed resistance resistor?

[charlie]

lol...
buy MSI!

Does anyone (macci?) have access to the Winbond W83303D datasheet? Winbond doesn't have a datasheet for it on their website. A google search doesn't turn up anything useful. For some reason the R50 mod can only give me +0.2V max, otherwise my system won't post, and I have to decrease the resistance. I'd like to check out the datasheet to figure out what's going on.

[macci]

I just looked at 8RDA+ and NF2 vmods and figured the W83303D would work in a similar way. Tried to find the datasheet too but no luck.
