Abit Guru.. Sasqui..??

[trog100]

is yours the same as mine dude..?? my AX8 board has a little guru chip on it..

i know u have different chipset just wondering if the gurus are the same

mine comes with three none adjustable default settings normal.. turbo and quiet (which aint quiet) which i dont use..

three user settings and one called default which seems to mirror whatever u set the softmenu thing at..

the user settings let u set fsb speed.. voltages and fan speeds.. u end up with three profiles.. i have user1 at 2.6.. user2 at 2.75 and user3 at 2.9.. all voltages set acccordingly.. up to 2.6 i leave em as default.. above i tweak em a bit..

as for the softmenue.. i am bit a puzzled about that but whatever u put in it ends up as the "default" setting i have mine at 2.4 gig..

configure autodrive lets u associate any program with any profile.. all my games i have linked to user2 2.75 gig.. for decoding.. winrar.. quickpar and similar things i have linked to user3 2.9 gig.. the odd thing is linked to user1 2.6.. when these progs shut down it reverts back to the "default" which in my case is 2.4 gig.. the real 3700 default of 2.2 gig never gets used..

basically the machine boots at 2.4 gig and stays there till something gets run that matches a profile then it adjusts accordingly when left in autodrive as it mostly is..

u can select any of the four profiles manually and it all stays there.. it all seems to remember which profile it was in the next time it boots up.. with a system crash or improper shutdown of guru it goes back to the softmenue default at next boot up 2.4 in my case..

atitool does pretty much the same with the grfx card.. just cranks speeds up when in 3D and goes back to a slower speed when back in 2D mode.. again its all done pretty much the same just linking 3D to user set profiles/saves...

together the pair of em work very well.. basically the machine works pretty much like a laptop does only with more user control.. i have come to the conclusion all machines should work this way.. he he..

the abit stuff works so well i think cos of the special chip which lets the software talk to the hardware.. the abit via based AX8 board is a little gem to be honest.. runs far cooler than an nforce based board seems to.. has all the clocking options and just works with no problems..

i must admit to buying via cos they come cheaper.. but this one is as good as any..

i even ditched my creative sound card.. i have always had choppyness with onboard sound before.. this one works perfectly.. cant tell the difference tween it and the creative card.. except the interface is better..

Wow, that was quite a download! It looks almost exactly the same. I think some of the quirkyness lies in the bios itself - as it seems whatever I can't do in BIOS, I also can't do in the uGuru utility. Here's a few:

1) To overclock, I have to bump my FSB at 5-10 mhz increments at a time. If I do one huge leap, it fails and reverts back to stock.

2) I can't get the memory hub speed (Northbridge?), to lock to the FSB, when the CPU is set to "User Defined" (even if I set it to stock 200... "204")! If I select that option and save, it just goes right back to "800". The memory is indeed running at the correct 1:1 speed though according to CPU-Z and uGuru.

3) I can't change the CPU multiplier (I think the 630 does not have this option anyway, while the 640+ CPUs do?).

4) The FSBCIEx speed cannot be changed to anything except "AUTO", so I don't know what it's running at. This may be a side effect of #2 as the PCIex talks directly to the northbirdge.

I can't complain - the system is ROCK solid at 247 FSB - I have not had a single BSOD or lockup yet in two weeks of semi-heavy use. If I go to 248, it gets flaky!

Also, since I'm watercooling, no fan control for the CPU. I do have 3 AUX Case fans to the mobo that I could control I think, but I haven't experimeted with those options. I also wanted to mess around with mmory timings.

Thanks for the help - share any more insights!

i have come to the conclusion all machines should work this way.. he he..

The asus boards also come with a very similar aplication. And the auto clock control that you have is called AI NOS on the Asus stuff. It's all very similar.

I have the oposite problem to sasqui when it comes to raising the fsb. Whereas if he raises his too fast it doesn't work, if i raise mine too often it will freeze up and i'll have to restart.

I'm not sure how AIBooster interfaces with the motherboard, but i should imagine it's very similar.

Abit and Asus both have the right idea! This is definatly how all computers should be!!

3) I can't change the CPU multiplier (I think the 630 does not have this option anyway, while the 640+ CPUs do?).

No, i don't think any of the 6x0 series have the unlocked multiplier, although some motherboards allow you to force the multiplier to 14x as opposed to the 16x that my 640 has as default. Thats a very handy feature. But i think the 630 has 14x by default?

I read an article about the "trickery" that goes on to change the multiplier, it's all in the motherboard (and CPU) from what I read and quite complicated to understand... the words "pulse-width modulation" come to mind.

The multiplier of the 630 is 15x. 200FSB x15 = 3K KHz (3.0 GHz), so infrared - your stock multipler is 16x. (3.2 Ghz).

Oh, there was one other quirk that I found out regarding the temp calibration of the AG8. With water, my CPU runs at 11c idle and 27c load. Now that's not possible as my room temp is 20c! So if I add say 15c to those for a correction, it's more like 26c idle and 43c load. Abit supposedly fixed a calibration problem with the latest BIOS, but not for my CPU...

Here's the option that won't "stick" when CPU speed is "User Defined":

only a 64k jpg.. must be a slow connection the server is in germany..

due to the different chipset any insights might not be of value. but i do have a few quirks..

what i had to do in the bios was alter my htt speed multiplyer from x5 to x4.. thow it all seemed to work just left at default.. even at 5x 270.. which would have put it to 1350..

the bios memory settings are a bit puzzling.. i have three instead of the more usual two.. auto.. spd.. and manual.. whats the difference tween auto and spd i never worked out..

alter my memory divider to less than 1-1.. it gave me 160 instead of the expected 166.. just how the divider works thow i think.. i thought there might be an option to lock the memory at 200 but there isnt.. thats what auto might be for dunno but if it is it dosnt work.. i never messed with memory timings that much just changed the single cas 3 setting to cas 2.5.. guru ups the voltage to 2.8 at the higher speeds..

my bios has settiings for lowering the cpu multiplyer.. it says that "cool and quiet" must be turned off for this to work.. it seems to accept a lower multiplyer okay but dosnt change it from its default 11 x in reality.. so that dosnt work even thow according to the bios it seems to.. when u leave the bios it just goes back to 11 x..

my windows guru has an option for changeing PCIE speeds but i havent altered it from its default..

i have three 82mm case fans and one psu fan.. the psu fan is auto controled by the psu its self.. it exhausts from the top rear of the case and runs very quite.. my two rear case fans blow in.. i have wired them both into the same plug which goes into the mobo "system" fan connector.. guru lets me speed control these two..

my one case fan in the side of the case has its own rheostat built in but it dosnt slow the fan down far enough to silence it.. i also have a zalman fanmate in series with it.. the fan is a led one and is more for show than anything else.. i cant guru control this one.. u probably could by useing the spare cpu socket.. mine is in use..

i also have an empty fan hole with just a grill on it in the top of the case.. the modular psu connectors hit the fan body so it got removed.. it hasnt been missed.. he he

i must admit i am surprized just how little air needs moving thru the case to keep it at just 1.5c over room ambient at idle.. praps 2c over room everthing going flat out.. the fans never speed up much.. the loadest thing i now have is 250 gig usb drive sat next to the PC.. it does have an off switch on it thow.. he he

my guru dosnt mind big speed changes.. i have it set to run at boot thru the softmenue.. prior to be doing that all the fans went full speed at boot up and then slowed down when in windows.. one thing that niggles me is it dosnt appear minimized i have to do that manually.. if i shut it off instead of minimizing it the autdrive dosnt work..atitool beats it in this repsect..

all in all.. i have two less fans than i used to have with my socket A system.. the old psu had two.. the fans i have left all run bleow 2000 rpm.. less than 2000 rpms seems the sweet spot for normal case fans noise wise.. and the whole case runs cooler..

apart from not having a toasty creative sound card in there and the grfx card exhausting out the case i have no logical explanation for this but it just is..

my memory timing also seem quite good for oem type memory running only just over 400 at basic cas 2.5 timing.. etra cpu speed seems to bump the bandwidth up even if the memory itself dosnt run faster..

AMD Clearly showing it's superior memory bandwidth with on chip memory controller... I assume you are getting those numbers at the 220 FSB overclock?

My image is on a server in the US, don't get the reference to Germany?

 

[trog100]

no those particular figures are with the required "fsb" overclock (264) to take the cpu up to 2.9 gig.. the memory itself is running a smidge over 200/400.. roughly similar to default speed..

at the 220 u mention the memory would be going slower at about 175/350 this would produce about 1000 less in sandra just over 5000.. the so called "fsb" which isnt really the fsb in the 64 bit system just a figure that everything else is governed by dosnt really affect things.. however the faster cpu speed does.. back to the memory controler on chip thing..

basically with the cpu at its default 2.2 and the memory at its default 200/400 the sandra score would be around the 5000 figure.. upping the cpu speed to 2.9 without upping the memory speed above the 200/400 puts the sandra figure up to 6000-ish.. the thing called the HTT speed of 1000 (fsb..???) is roughly the same with my overclock cos i have lowered the muliplyer from 5 to 4..

basically what seems to have happened is the cpu speed has taken over from the fsb speed as the governer to performance memory bandwidth wise.. the old idea of useing a lower cpu multiplyer and higher fsb speed to gain performance dosnt seem to apply any more.. as the cpu speed goes up the onchip memory controler speed goes up with it.. the result seems pretty much the same as useing a higher fsb speed did before with the memory controler on the mobo..

quite large differences in sandra also dont seem to make that much dfference in real life performance either.. a %20 difference in sandra seems to relate to less than a %2 difference in real life performance.. it seems it me that raw cpu speed is the key with the 64 bit chip.. nothing else seems to matter that much.. the old mobo fsb motherboard bottleneck seems to have been taken away..

this leads me to believe the coming new socket and move to ddr2 at 300 isnt going to give any noticable performance increase over the current system.. it will leave room for future gains but at first i dont think it will produce any..

ignore the server in germany reference its just where my pics are stored.. he he he

Hey, look at the thread entitled: PCIExpress BUS Speed / SATA Controller? I think I found where my problem lies, but yet to land on a solution.
