cant OC DFI Infinity 975X/G

well, its really simple.
Ive tried to OC with almost no knowledge, only the most basic stuff...

and I cant get over 320 FSB, on 320 ith a prime 95 stability test the NB goes up to 65c and the CPU is about 53c

and its really strange, cuz ive been told that I should be able to get about 370.

so I guess that im doing something wrong. can someone guide me, step by step, how to OC that thing?

thats the rig:

Intel Core 2 Duo E6400
DFI Infinity 975X/G
Corsair XMS2 512MBx2 800Mhz
Sapphire X1900XT
Enermax 420W

B.T.W - all cooling is stock

What mem divider are you using? Most people can't seem to get over 320 without using 4:3 (on the current official BIOS). And even then the crap out looks to be 370-380.

I just bought this board myself. Seems to be the most promising of the lot with the exception of the P5B and that vaporware (at least in the US) Biostar.

1) how do i change dividers?
2) there is a pretty new bios out (early august), how can i check what version i have?
3) if theres a newer BIOS than mine out, shoud i upgrade?

1) I don't have the bios in front of me, there are a couple of screenshots of it in some of the Infinity threads.
2) 731 is the latest official one I believe.
3) It should say somewhere either during post or in the bios itself. I think CPU-Z will tell you as well.

1) here you go now can you tell me how to change dividers?
2) my BIOS version is 6.00 PG, can you give me a link to the newest one?
3) 6.00 PG

1) I believe its under the DRAM timings in (the first option).

I should note that I have yet to receive this board. I am helping you based on the 30+ hours I spent reading every bit of info I could on the board before buying it.

1) ok
2) 99.999% sure. Version 731, like I mentioned above. Whatever you do, if you see ANY BIOS being offered anywhere marked 814 or 816, don't get it yet, at least two people have killed their BIOS with that version.

Edit: I have a hockey game in 45 minutes, I have to go. Hopefully one of the other 975X/G owners I see trolling right now can help.

BIOS update does nothing.
and the memory divider is already 1:1
so what can I do else!?
its strange!
ive got a system that supposed to be a killer OCer but I cant OC!

i personally dont understand the dividers on Intel boards very well. AMD's are much easier to understand. I will have this board tomorrow though so hopefully we'll figure something out.
08-23-2006, 03:08 PM
Sir Random

You probably just need to raise the vcore to 1.35v to carry on past 320fsb.

You might need to raise it a bit more when you reach 370~390
08-23-2006, 03:09 PM

I'm here, wrong time listed for my game.

Like I said, to get above 320 you will need to go to the 4:3 divider probably.

The only people getting above 320 with 1:1 that I have seen have been doing it with an experimental BIOS. Don't ask for it.

but there isn't a divider setting.
the only thing that does that is a setting that let you set the memory speed (400, 533, 667, 800), so I set it to 533. should I change it?

and on 320 my NB temp is getting really high, up to 64. is it too high?

Change it to 400, that's equivalent to 4:3 (266:200 / 533:400)

that is the divider. when he says 4:3, thats what most people are used to. this board though fancily calculates it by your FSB. for instance if your FSB is 100, then when it says 133mhz as a selection, that is '4:3'. RAM:FSB 4:3.

so I should change my mem speed to 400?
08-23-2006, 03:18 PM

but what about the temps?
64 fir the NB isn't too much?
08-23-2006, 03:18 PM
AndrewZorn

whether your memory is capable of DDR2-800 or 400mhz (the 400mhz that it lets you select is DDR2-800) i do not know

EDIT my 'chipset' temperature (which is the SB not the NB from what i hear) hovers at 46-53*C (actually i think my AS5 is finally baking in because this is the first time ive seen 47*C after its been on a while) (the 53*C was before this baking in so my max might even be lower) (this is the first time ive actually seen AS5 bake in, every cpu and chipset redo ive ever done temps never changed from day one until now)
08-23-2006, 03:20 PM

wait, should I get it down to 400, or up to 800?!
08-23-2006, 03:22 PM

Down to 400 (DDR makes it 800, Double data rate)

Some people at DFI street have mentioned the NB getting quite hot. I plan to put a 40mm fan on mine until I see a good deal on a heatpiped aftermarket cooler. I was looking at the Spirit II maybe.

Sorry for the confusion about what 4:3 actually meant.
08-23-2006, 03:23 PM
Sir Random

I think you'll still need to raise your vcore to 1.35v to get much higher than 320

Your ram should have worked at 1:1 320fsb (640Mhz), unless it's 533Mhz?
08-23-2006, 03:27 PM
AndrewZorn

ok ignore all my comments about the chipset temps and the way the board autocalculates the mem frequency...

somehow despite the title and post i thought you had the P5W

though i may still be correct if i am its only by luck
08-23-2006, 03:28 PM

One thing you do have going for you is I believe Kunaak mentioned that he was seeing the higher FSB when there was only 1 GB total of memory in the system (on the experimental BIOS). I'm not 100% sure why, maybe it has something to do with addressing within the NB. So there is some hope for you when that BIOS becomes stable.

You probably need to raise the vdimm too. What ram are you using?

You won't get very far without raising the vcore and vdimm.

If you are running at 320 Mhz and 533 DRAM, then you are already basically at 4:3 I believe (320:240, 240x2 = 480). To run 4:3 at 370 Mhz, you need ram to be at (370/4)*3*2=555, which is greater than 533, so if you cannot choose 555 I *think* you have to choose 667.

so you think that 470FSB and 667MEM will boot?
ill try

but when i set the memory to 800mhz and FSB ti 320 it didnt boot... why is that?

Finally!
Im now on 350 FSB, perfectly stable, but the chipset is hot. at max preassuer it gets up to 67 degrees (celcius)

Ive found a 40MM fan and im now installing it on the heat sint, hope it will help, and get me to 370 and more!

Anything other than the 4:3 (400) divider will pretty much limit you to around 320ish fsb with any of the current bios's.

370ish seems to be the limit for most on this board, maybe things will change with a newer bios, maybe not.

Anyways cool the NB, I just have a fan blowing on mine, keeps it in the 4xC range.
08-23-2006, 05:02 PM

My NB is on 67 degrees on stress, its extreamly hot!
do you think that something like this will cool it down a bit?
or maybe the AKASA AK-210?

Copper base is nearly mirror polished and looks like a mirror on mine when I pulled from its' box. All required pieces are in the box for installation on 975X/G.

no, you see, I got the memory down to 400mhz
and I dont mean 400 and its 800 because of the DDR.
I mean 400mhz, like all DDR1 modules.

and other memory speed wont boot!

And about the chipset cooling, I just cant get the tow things you suggested.

Ive been using EVEREST to monitor my temps, and then Ive noticed that the CPU isnt warming up after all this OC, only by a degree or two.

so Ive installed the DFI siftware, Smart Guardian, and look what happned:

So even if Ill get a better cooling it wont help?

but what about the memory, why cant I use it on 800Mhz?
08-24-2006, 01:16 PM

You wont get anything better until a new BIOS comes out. But better cooling never hurts.

At 4:3 to be using your memory at 800, you would need a FSB at 533, which you wont get, no chance, maybe not even with the new bios.

Hopefully with the new bios you will be able to do FSB400 1:1 for the 800 memory.

The divider equation:

(FSB/1st Divider #)*2nd divider #*2 = Memory clock

Which is why you are getting 375 and 560 @ 4:3: (375/4)*3*2=562.5

I put together this chart for showing the dividers:
Remember you need to choose a BIOS value higher than the one marked for each FSB and divider. I think there is typically some play in the numbers, they may vary by a couple of percentage points for each board.
The red outlined is the highest I have seen for BIOS 7/31.

nah dont fix it, what i mean is how you used effective speed instead of actuall speed, it's no big deal really, i just have to divide by 2.

Oh yeah, I was considering putting BOTH on there and labeling them as such but I did not want to clutter it up.

No problem, I just saw a bunch of people (AMD guys I guess) who were having trouble grasping the whole divider concept, figured I had the time, so I'd lend a hand.

Well got my setup running tonight. I was going to wait to OC but I decided to give it a shot. I can't get it to run over 320 Mhz no matter what I do. I obviously tried 4:3 first, and tried to clock it at various places between 325 and 375, all failed. Then I tried a bunch of other stuff, no go.

I didn't try too much dealing with vcore, I was a little confused with the two settings there, one was the offset (default + that value, which in the manual was listed as vcore) and then there was this VTT, which I left at 1.20 (its max option was only 1.35), so I wasn't too sure if I needed to change the VTT one as well, so I didn't. Plus if Blaze can get 375 at stock I should be able to get 325 at stock.

It is running stable at 320 with the 2:3(800) divider right now. Temps (according to core temp) are decently high 63/59 @ idle, 67/67 under load.

I will be needing a NB fan though, I popped the sink off and swapped the stock crap with AS5 already but it is pretty hot to the touch. Bios says its about 50 C.
