Rawwrr!! VModded Shuttle AN50R v1.3 now!

[`schr0et]

Just finished the VMod...

Before mod on 'AUTO' bios was reading 2.54

After mod 'AUTO' read 2.65

I got my ram @ 3.42V now :D

Using 2x 256 KHX3000 (single sided, slots 1&3 heatspreaders on)

Just booted in @ 220x10, gotta love this Shuttle board! (LOL I'm not saying 220x10 is the highest I've ever gotten!! I'm just using that while I download some benchies :):)

I've used ASUS K8V Deluxe, Gigabyte K8N Pro and neither of those compare to this baby!

Gonna download SiSoft and CPUZ since I just got this mobo 2 days ago and pretty much was only playing games on it lol!

Wish me luck gonna shoot for 280+ FSB :up:

Sounds to me like user error on the previous two boards.. While yes the shuttle is a OK motherboard the way you just knocked the other two make me believe that obviously you didn't know what your where doing with the other two boards.

Congrat's that you finaly got a motherboard to 220mhz. :)

Man.. lighten up. :stick:

Congrats man, we all know the AN50R's are the best o/c A64 boards. Lets see 280FSB :D

[`schr0et]

LOL I wasn't saying it was "amazing" for me to get 220 mhz, by golly I was running 250x9 on my K8N PRO for a good week.

I was/am saying that in my opinion this Shuttle AN50R is much better than my previous two boards because of these following reasons:

1. Bios is much more complete, once flashed to 2/9/04 bios you have memtimgs options + voltage + multiplier changing ability

2. Volts are derived from the 5V line instead of the 3.3V line allowing a much higher "maximum" so to speak limit for your ram.

3. There's a Power and Reset button built onto the motherboard, never have seen that on any motherboard I ever bought, I thought that was neat ;)

That being said I wasn't bragging about being able to boot in @ 220x10 haha :ROTF: I did that with every A64 board I owned from day one, I was more happy with the overall results of this board compared to my previous two.

On my ASUS K8V Deluxe I very well couldn't get past 237 FSB because there was no AGP lock on the board so my Radeon 9800 Pro kept crapping out :(

The Gigabyte K8N Pro is actually a really nice board, but it still does not have the ability to change multiplier thru bios.

Sorry if it sounded like I was baggin on those boards but I'm just ecstatic right now because of this Shuttle AN50R, I'm a first time Shuttle buyer previously I always stuck to more established MOBO suppliers i.e. ASUS, ABIT blah blah

Cheers!!

:toast:

[paul007]

yeah sorry didn't mean any offense towards you at all just alot of sarcasim. :)

Nice work and sorry If I came off hard..

[Çhrist0ph]

i thought too much voltage to mem kills A64's? i heard 3.0v+ and up is risking it

sorry, im still restricted to 32 bits of computing power :(

[`schr0et]

No not really, the only thing that has been killing A64's is unstable voltage. Voltage fluctuations when some people switched from AUTO to 2.6 or 2.6 to 2.8 it would kill the mem controller on the A64.

But for others (me) who leave the mem volts @ Auto and only change thru VR's the CPU is completely fine.

Besides I've been running 3.42 for nearly an Hour now and it hasn't fluctuated yet prompting me to think that all is well for now ;)

These sticks needed 3.39 volts to hit 262 FSB 2-2-2-5 on my Infinity on a Barton 2500 315, so I'm giving it 3.42 just to warm it up.

And I just checked my ram to see if they were getting warm, but theyre cool to the touch.

I'll keep ya guys posted once I stop playing CS :D

EDIT:

Well I started pushing this baby more, tried going from 220x10 in bios directly to 250x10 and well... :lol: it didn't really boot haha

So I had to clear CMOS, made sure everything was ok... Bios still reported Ram volt @ 3.42 stable so I let a sigh of releif and pushed it down to 230x10 and its stable in Super Pi, loops of 3DMark and SiSoft mem burner.

Damn I didn't think this chippy had so much potential,

Guess third times the charm comes to mind :D

BTW: I'm still on stock cooler as I don't feel like taking apart the watercooling on my brothers Infinity rig.

[Alex08]

i had the same setup at one time,

i only got mine to 2.5 = 10 x 250 before i killed it, i had my vdimm around 3.45-3.5, i also had my thing on auto. But i think it was when i restarted the comp, the lines might have gotten a jolt and dead went the chip.

[Clew]

Shuttle AN50R rocks indeed

Heres another one from me, same system.

Holy schnitt! 312fsb :slobber: could u post a cpu-z memory screenshot?
lol 312 is 624mhz bus! :banana:

[STEvil]

`schr0et - Tried putting a DMM on the memory voltage reading points and watching to see if it bounces during reboots/startup/shutdown?

[Alex08]

ditto that, i would also like to know what happens during the reboots and startups.

[saaya]

just DONT use the bios to change vdimm! and i wouldnt go above 3.5v vdimm either.

good luck! :toast:

btw, was it hard to mod?

[Alex08]

modding on this board is very very simple, it's been the easiest mod i've done with help from mickeymouse.

[Formann]

Me also luuves the AN50R.. I also love my Twinmos BH5 sticks. 35$ each.. :D


280 1:1 2.5-2-2-5 @ 3.45vdimm - LTD 2.5
http://privat.bluezone.no/forman/images/sandra280.JPG


Never mind the "low" score in sandra. Its cause of the low cpu clock. 2.38Ghz. Was using the stock HSF and 280*9 is more than it can handle. The chip wasn´t all that either. May it R.I.P
Getting a new one today tho.. :D

I don't think that was 1:1.

[xxORBxx]

lol ill be checking back, to see when the A64 dies. I loves the AN50R till outta nowhere it decided auto should go from 3.3v to 3.6v

The chip didnt last long to say the least. Just be careful with that vdimm.

[sexsymbol]

So the best thing for doing the vdimm mod is to set to auto in bios. Power down the computer do the mod and switch on. Get into the bios health status and with the vr set the vdimm you like? That a safe way of doing the mod??

[Jeff]

That's the way I did it SS. I haven't changed the BIOS setting at all and I've dialed in up to 3.6v for the memory. 3.3v to 3.6v seems to happen extremely fast so be careful.

[`schr0et]

Ya I used 2x 1K 15Turn VR's and it was a :banana::banana::banana::banana::banana: to get it to go from 2.65V to 2.72 but then it started jumping faster and faster...

I went from 2.92 to 3.14 by turning each VR half way... I was like crap...

Then 3.14 to 3.42 half way again...

I don't like to use DMM to monitor volts because there's of course a chance to short something out and kill everything, so I decideed for now I would just monitor the RAM volts using the shuttle BIOS since it has that option :)

[`schr0et]

It wasn't 1:1. notice his memory is only running @ 202 FSB when his HTT is running 312?

;)

[saaya]

i dont trust those bios readings, especially since some mods increase volts without the bios showing it.

the voltage readings on my a7n8x are superb! but if it was about the survival of my chip i wouldnt trust it :D

[`schr0et]

Maybe so, but I've killed a A64 chippy because I was too busy checking the voltages instead of monitoring what was going on my screen :-\

I ended up creating a spark and off goes my 3200+ to CPU heaven :(

[`schr0et]

weird... whenever I try changing multi thru bios system won't boot and I have to clear CMOS to get it to boot...

And if I try clockgen the system just freezes...

Gayness!

[Goldlocke]

as it may not have come to your knowing yet:
1.) CnQ is working correctly with just 1 stick of RAM!
2.) bios AN50S025 has no working multis accept AUTO. though you're able to change it will never post -> CMOS clear.

[shimmishim]

questiona bout clockgen and mults:

my ram is good up to about 250 mhz 1:1 @ 2-2-2-6 with 3.4 volts

I'd actually like to use like an 11x mult so I can run 1:1 instead of 5:6 like i am right now (2.6 ghz but ram at 217.5)

What's the proper way of using clockgen?

I heard that you're supposed to set the fsb to 201 in the bios and then go into windows and adjust the mults this way.

Is this correct?

Also, do you think changing cas from 2 to 2.5 will help me get more mhz? (leaving all other timings on auto except CAS)

[Goldlocke]

shimmishim, depends on what A64 you got.
3200+ max. reachable multi is 10x
3400+ max. is 11x

you can't go over that max. even with clockgen. you can use all multis that are equal or lower than your default multi.

[Zeus]

Man! I still haven't worked up enough bawls to do the Vdimm mod. :(

So many ppl run their systems fine with high Vdimm, but others die so easily...

It's not that i don't want to solder but the thought of killing such an expensive chip... :rolleyes:

I really have to have some more Vdimm as my stick of Hyper-X 3200 (BH-5) is crapping out at 228 and won't boot with CAS2,5.

Maybe i need some encouragement?

BUMP

I'm at this now:

http://www.gonad.org/upload/images/240x10.jpg

:up:

EDIT: Holy crap this chippy is mad nice! Better than my previous two A64's!! I got nearly 200 point increase in SiSoft sandra just going from 230x10 to 240x10 :slobber:

Mind you, I'm still on stock cooling :D. I think I'm going to have to mod my Lian Li case to fit watercooling, I'm dreaming about what this chip can do if only I had a prommy :(

[QuadDamage]

nice but 3.42V and only 240mhz? not to mention it's cas 2.5. are you sure you need that voltage to hit 240fsb?

[`schr0et]

Naw I don't need 3.42 to hit 240, right now I'm trying to see what the max this CPU can reach with 10x multi :up:

I only need 3.3 to hit 260 FSB on these sticks 2-2-2-5 on my DFI Infinity, but the 3.42 VDimm makes my rig super stable and it doesn't fluctuate when I monitor it with a DMM so I'm leaving it alone ;)

Also 99% A64 don't seem to like CAS 2 much, I can't boot in @ CAS 2 but there's no performance drop when compared between CAS 2 and CAS 2.5

[Dagalidis]

Regarding Overcclocking limit for ASUS K8V - D it was able to me to have almost stable 246 FSB 1:1 the mem and getting a total 2462 MHZ of my A64 3200+ with AMD Stock COOLING........ :D

The highest not stable FSB for my ASUS is 261 FSB and of cource thanks god that my Nvidia 5900fx can work fine with high AGP.....
YES ATI is a BIG LIMIT at every VIA A64 Based Board...... ;)

Here is my 56310 Aquamark03 Score for 246 FSB.... (http://arc.aquamark3.com/arc/arc_view.php?run=875914380)

And sex symbol. I think the safest way to run vdimm through this board is to set the bios to 2.9v and then set the vr to the highest value that you would ever run. This way you know it cant go past that. But with auto, you set it to 3.4 which really should be 2.6 or whatever auto usually go to, and then it decided you need more vdimm like mine did and the 2.9 setting is like 3.8v or something crazy like that.

[`schr0et]

Was priming 240x10 and temps hit 72C :eek:

MBM alarm went off, had to turn off prime.

Everything still worked fine tho... I touched my ram sticks the farther KHX3000 on slot 3 is actually getting pretty warm to the touch, while the KHX3000 in slot 1 next to the stock AMD HSF is cool to the touch, guess I should add a fan over those sticks :rolleyes:

That was exactly my thought and i posted it in some other thread also. ;)
Did you do it that way?
Since 2.9V is the highest setting in bios it can never exceed the voltage you adjust with the VR's.
Btw, nice OC! :toast:

NO! leave the vdimm setting on auto and only adjust it with the variable resistor! safest way and ONLY way i would raise the vdimm.

is there wpcrset for nf3 boards so it automatically changes the multi and fsb after you booted up?

[xxORBxx]

Well so far the safest way killed my chip and the dangerous way has kept it alive for 2 weeks so i guess im just lucky. When i had mine set to auto, the vdimm went from 3.3 to 3.6 without me touching a VR so choose whichever way you think is best but i choose the risky way.

Most likely because you had your VR set improperly ( not saying you don't know what your doing etc..)

I did mines this way:

2x 1K 15 Turn both set to 1K before soldering wires, checked to make sure 1K on each after soldering wire, checked again to make sure combined 2K after soldering both together.

Left everything @ stock in bios shut down did the mod powered up.

AUTO read 2.65 now instead of the normal 2.54

I noticed that when I only turned 1 of the VR the voltages were unstable usually jumping +/- .3V When I used BOTH VR's voltages never changed always stayed at what I left it.

Even after numerous random reboots and cold boots my chippy is still dandy :up:

I just ran 3DMark01 with 2.4Ghz 240 1:1 with 9800 Pro @ 420/380 and got the crap tastic score that is 22K

http://service.futuremark.com/compare?2k1=7627986

EDIT: NVM thought my 9800 Pro mem was @ 380 but I only set it to 367 :rolleyes:

[xxORBxx]

Yeah, i use both vrs to change the voltage, its not jummpy at all. Only that one time. I had it running good for a while too. Score in sig that way too. Minutes before it died.

Heres are the pics, see anything wrong?

looks exactly the same way i had mine.

have you already killed an a64 chip ORB?

edit: nevermind I just saw your 3dmark results. sorry to hear that.

[Zeus]

Giving it another thought, if you have to clear cmos, the bios will default vdimm to auto, so you have to manually set it again to 2.9V with the mod hooked up....dangerous me thinks. :(

So maybe leaving it on auto is still the safest way?

Gonna do the Vdimm mod tommorow but i will be a bit conservative on the voltages, 3.15V will do for me, i don't think i'm gonna have to go over 240.

Setting 3.15V leaves some room for unexpected higher voltages or spikes i hope.

Originally posted by `schr0et

Wrong again mate. It is very easy to change multi in bios without using clockgen..Who would want to use clockgen each time you boot up. All you have to do is flash the K8NNXP-940 bios and lower multis are unlocked.

Results look good so far and Im glad that your chip is still working with that high vdimm. Above 3.0v is danger zone but some run @ 3.3v without any problems, like CCC.Good luck and I hope you will be able to get 2.5~2.6stable on water :toast:

Other than that I guess its just luck of the draw :rolleyes:


BTW Phyrox:

I've never tried that KNNXP bios guess that would've helped :rolleyes:

My point wasn't reaching high FSB I did that on my K8N Pro just fine, this is just my very biased opinion :D I really do love this Shuttle AN50R and for whatever strange reasons it may be that I like, it still doesn't change the fact that I like it ;)

Well as you would know it, this morning my dad was on my comp... thought he recognized a name in his hotmail inbox opened it and a lovely winlogon.exe worm decided to make itself a new home on my network....

Needless to say I've been busy reformatting all my HD's because:

A. Anti-Virus software = bull:banana::banana::banana::banana::banana:, they don't even delete half the files, only disable it so once you stop using their pos software you get those friendly virus' back

B. It was about time I got my lazy ass and did something important, I finally burned cd's of all my important files that I use whenever I do a fresh instal... i.e. SP1a, DX9B, blah blah blah

But goes to show you, while I was installing my OS and stuff I didn't realize I was still running 240x10 @ 1.7VCore, 3.42VDimm haha guess 2.4Ghz is stable :toast:

I'll be working on my watercooling rig for sure cause this chippy has shown its a worthwhile investment to spend my time on :D

I'll also be doing VGPU + VDDR + VDDQ mods on my 9800 Pro tommorow because I'm soldering Iron happy ;)

I think I wanna do the 9800 Pro VMods using an DIP switch

Just a heads up guys :up:

Which board are you planning to use though: K8N-Pro or AN50R...@ reasons why I didnt go with the shuttle:(1) need to do mods to prommy bracket to get it to fit(2) kills lots of a64s especially w/ vmods...the k8npro does not jump all over the placeo n auto.

[Zeus]

Wow, 3,6Gig, now that would kick some serious ass! :D
I see you 3.3V rail is at 3.6V... back it off mate, it's gonna kill your CPU/mobo.

A high 3.3V rail was only usefull for NF7 boards or maybe Gigabyte boards but it won't do your Shuttle any favours.

The Shuttle is feeding the mem of the 5V rail.

Now what did you change to get clockgen working?
Setting everything to auto, right?

Nice going on your setup, but be carefull with all these high voltages your running, that's kinda asking for dead CPU's.

[`schr0et]

Only thing I changed to get Clock Gen working was flashing back to the 10/30/03 bios from using AN50S025 bios.

And the high 3.3 line will be fine, memtest is reading no fluctuatinga nd its reporting 3.57.

My 5V line on the other hand makes me laugh...

Mosfets and molex report 5.46 without fluctuation, bios reports 5.42 without flucuation... MBM5 reports 3.10 :ROTF:

[RootX]

Guys, there's something strange going on with mem timings. It looks as if there's no performance gain by running them tight.

I've run the same test `schr0et did, the only difference is the ram.
I'm using 1x512 4000 ocz gold.

[QuadDamage]

because sadra is a synthetic bench. Try comparing in 3DMark. tight timigs vs slack timings = at least 500 points diffrence.

That's what I thought in the first place, but sandra used to report different results according to different memory timings.
Anyway, the superpi 1M is also a quick test, maybe the difference will be visible under the 32M test or 3dmark like u said.
:)

[Phyrox]

looking good so far keep up the good work!~

[Formann]

After trying a KHX3000/256 my AN50R wont boot untill I turn the vmem-pot to a setting that yields 2.8vdimm or below. Its a PITA to turn it down everytime Im booting my rig, cause im using 2x1k pots which are 20turn.
If i run like 3.4vdimm and try to switch it on, NOTHING happens.. :mad:

Anyone else experienced this?

[`schr0et]

Nope, I have my 2X 1K 15 turns set to yield 3.42V

And trust me when I say this, I have put my volt mod thru numerous tests to make sure its stable which includes and is not limited to:

randomly shutting down without any purpose, randomly hitting reset over and over. Randomly turning power on and off.

And of course the regular shutting on and off for the purpose of overclocking, and my volts are just dandy and haven't fluctuated at all.

The only time I've noticed that my rail is a bit different is if I shut my computer off for say 12 hrs and cold boot my voltages will read 3.40 instead of 3.42, but I think that has more to do with my power supply than the VMods.
