SN41G2V2 can i change the vcore or not?

[scottatwittenberg]

i am thinking of buying a SN41G2V2
it says fsb 333... and supposedly you can't change the vcore..

so, should i get one? i would put either an mp2400+ or an xp2500+

i would rather get the mp and push the fsb up to 400, but i don't know if i even could on a SN41G2V2 ... and then you can't touch the voltage.. or is the solution just to get a p4 based shuttle, since shuttle seems to favor intel for some reason? i don't want to spend the extra money though...

Yes, the V2 has overclocking abilities similar to the SN45G. But it still has vdimm death probs, and the IGP chipset isnt nearly as overclockable as the 400.

Why would you want to use an MP cpu? Or is it that you already have one?
If you can get a mobile XP it is a good match for SFFs, but the XP2500 would do 200fsb fine etc.

If you don't plan on using the IGP, I'd say to get an SN45G, and picking up the 250w psu if thats important to you, or wait for the SN45G2 that includes it, or I think some other special editions like the dawn and dusk one includes it.

Yes, and it is clear that shuttle does favour building intel systems, but I guess thats only comparing socket A to 478

The motherboard in the V2 is the same as the V1, at least if it's the same rev2 board as was in the later ones like I have. No, there is no option in the BIOS to alter the voltage on the SN41. Yes, you can alter the voltage. You can alter the multiplier too in the same way. It involves either modifying the bridges or connecting CPU pins... which isn't too complicated, at least not nearly so much as it sounds. Some of the newer XP processors aren't able to be bridge modded though... the ones with the visible traces on the front. Not sure if the socket/pin tricks still work with it though. I have links if you are interested in trying this.
Oh, and to squelch what seems to be an incorrect rumor, no the SN41G2 isn't limited to 166FSB. It just doesn't OFFICIALLY support 200FSB. I have run mine at 200 just fine. You just need the ram for it, since you can't alter the ram voltage in BIOS either... unless of course either of these things changed with a newer revision of the board than the two I have owned.

[bleed3r]

well theres the v2 and then the v3 mobo right?

The v2 mobo is just the SN41G2, but the v3 is the SN41G2V2 and I'm pretty sure it has vcore and all that now, but people dont get much more than 200fsb.

[jsu718]

I know for certain that the rev1 was not able to do 200FSB most of the time just because it was the older revision of the Nforce chipset that couldn't handle it. The rev2 was made specifically after this, but before the "official" ultra chipset was named, and nearly all of them could do 200FSB, just not with the official support. There were no options in the BIOS to even TRY to go over 200. I think the SN45G went up to 250 in the BIOS, yes?

[bleed3r]

yep

I think when [H] reviewed it before they got it to 250 i think

Just need the ram, but only really have a chance with the SN45G v1 mobo that has vdimm that doesnt fry the mobo, because the v2 you'll be stuck at 2.6V and hard to get anywhere with that.

i would rather have the sn41g2 than the sn45 because i like the looks of it better... especially the buttons and such... also it has built in video which is actually a good thing at this point because i don't play games, but if i do decide to do so, i can throw in a good vid card and then do that triple monitor setup maybe??

i have never really overclocked anything, so if i would get the sn41g2v2B (b is for the black one) and an MP 2400+.. then could i push it to 400 fsb without changing the vcore?? or do you have to do that? and since it is 1.45 v, could i put it up to 1.6 and 400fsb and have it run just like it is a 3200+ or something?

or would i be better off with a 2500+ xp and not push it as far??

also, i don't understand vdimm.. i would have only guessed that you would have to increase the memory voltage if you were running it past spec... so i don't see why that would be a problem if i got solid pc3200.. shouldn't it run at 1:1 with the fsb all the way up to 400fsb?

[jsu718]

As for triple monitor setup, you will need a PCI card for that, as the onboard video, while dual-head, uses the AGP bus, so when you insert an AGP card, it takes over and you can't use the onboard video.
2500+ starts at 166 FSB, and lots of people got to 3200+ without ever increasing the Vcore. Vcore increase is simple though.
By MP 2400+ do you mean the MP set up for multi-processing, or did you mean Mobile?

[scottatwittenberg]

i mean mobile...

[jsu718]

i mean mobile...
Mobile Barton is absolutely the way to go right now.

[scottatwittenberg]

ok... here is what i am probably going to get... http://secure.newegg.com/app/WishList.asp?position=HISTORY&submit=VIEW&ID=788695

sn41g2v2b
2400+ mobile
what ram?? do i need real good ram since i can't change the vdimm?? or will the mushkin work?

[bleed3r]

Well, you will only need PC3200, so pretty much any will run at 2.6V

I don't know what I'm looking for in your link, but yeah, ram of your choice depending on your needs. What mushkin ram were you thinking of? If not much gaming or anything like you said, you could simply get basic or blue, or other cheaper ram non-mushkin

the answer to this title was never really answered in this thread, I'm away on holiday right now but would like to know if I can change the Vcore. I wasn't able to when I last looked but I have an old bios. I think its 016. Any definitive answers?

[scottatwittenberg]

well.. i bought the sn41g2v2,, in june i think.. long time ago.. and yes it can..

i can change the vcore from 1v to 2v.. but... i tried running it at 1.9v once it worked.. but 1.925v would cause it not to post.. and then i had to go through a whole long process which consisted of pulling the video card.. putting the cmos reset jumper to clear.. turning on the computer.. then turning it off, and putting the jumper back to regualr.. just to get it to post again. .the "del" key didn't work .. ir insert ir whatever it is..

also my sn41g2v2 doesn't like bh-5.. i can't get it to run at stock speeds in here.. but i have gotten it to work fine in another motherboard where i was able to raise the vdimm a bit.. i guess it wasn't too smart for me to buy ram that is notorious for needing high voltages, and just about the only motherboard out there that can't give it the voltage it needs..

but the motherboard does everything, except the vdimm.. i got the fsb up to 225 before.. i got the vcore up to 1.9v.. i have ran ram timings from 2-2-2-11 - 3-3-3-11 with few problems...

and it has been the most stable computer i ever had.. i restart it maybe once every 1wo weeks.. and that is only because i am changing things, installing, software etc.. hardware wise this thing could have run for the whole 7months or so i have had it straight with no problems, i think..

so there is the long answer to your short question.. my bios.. i have no idea what version it is allows the vcore to be changed from 1.0v all the way to 2.0v in .025v increments.. and it overvolts a bit.. the bios says 1.45 right now.. but any program i read the vcore with says 1.47 for example..

cool. Thx for the reply Scott, I'll be taking a look when I get back to the Hong. Just chillin in front of the fire in Austria right now...

you have to realize that i made that post 7 months ago.. or something like that.. look into the

sn45gv2
sn45gv3 (if you can wait a while, get that one)
sn41g2v3

but actually.. get an a64.. i don't see a good reason to get a socket A anymore.. the prices actually have gone up on the shuttle and the cpu that i have since i got mine..
