940BE & 720BE Ln2 Oc DDR2

[ShrimpBrime]

I'll start with a shot of PiMod 32m at 4400mhz. I found it strange that 17 minutes of LN2 at this speed and it benchmarks. But not 2 fsb bus more I get a non booting system.

Here's a couple of pictures to start. I may run a 32m on the 4100 at around 4.8ghz (on air) to compare to this DDR2 940BE chip. It should be interesting.

Oh yea and here's a temps shot. TMPIN 0 is cpu temp. Cores never showed below 0f/c and I ahve no idea what ACPI was showing. But at 109c, I don't think It would have posted.....

MMK, got a chance to run a PiMod 32m on the 4100 FX.

FX x4 processor speed was 4.8ghz multi only and the Memory was 933 stock timings.

1.6 vCore, you da man.

Tried up to 1.75v to pass the 4.4ghz wall and it did not a darn thing except use more LN.

LOL! You have nerves of steel Mr. Brime! I guess it is topped out, more voltage is not always the answer, but I forget the question...

[ShrimpBrime]

Question is...

Why would a cpu not post windows past x speed? Could have been I used an IDE drive?

1.75v is nothing. LN2 is plenty cold for it.

[maxgull]

IDE drive shouldn't make any difference, or I have never heard of the FSB speed having any effect on drive speed/xfer rates etc, I would assume, if FSB did have something to do with the SB, your disk xfer rates would increase as the FSB increased. It doesn't.
I think you just hit the wall, they all have one! You just found the bleeding edgeof your CPU. I think.

[ShrimpBrime]

Your probably correct.

[Mr.Scott]

Not necessarily. Try a different divider.

[ShrimpBrime]

20x was the only one that put me right at 4.4ghz.

At 2 fsb more, there's a bunch of H's all the way down the left side of the screen or nothing happens at all. But I can post bios over 4.4ghz and navigate.

So I'll def. give different dividers a shot!

Well in the meantime, I do have more SS's I could share!

[Mr.Scott]

Try different multi and FSB combos also. Could just be an FSB wall on the board and not the CPU at all.

[ShrimpBrime]

It does it with multi too.4.4ghz NP. 4.5ghz via multi does the exact same thing.

And I am using a bioflop board too.

Really I thought it was doing well for a C2 original gangsta 940BE chip

[Neox69]

Might be getting a 940 soon... Feeling ballsy?

[ShrimpBrime]

Yes, hi Neo. Good to see ya!!

And here is some more pictures

Many thanks to my brother Shawn as well for helping with set up and OC.

[ShrimpBrime]

Slap down some more OC'in pics here.

720BE running ddr2 on a biostar 8200 AM2+

Temps around -65 to -82 Centigrade running temp.

Really was a struggle running this one past 4600mhz.

Took out the 5770 and slapped in a much less aggressive card installed on a new W7 os with an SSD. I think these changes where good to go. Pressed for time, and running short on LN2, we gave it what we could in less than 3 hours time including the install of windows.

Enjoy!!

I can't help but feel like your clocks should be way better than that on ln2

Seems like something is really limiting you (similar chips should be doing at least 5.5-6.0ghz)

Yes Hi and welcome to EOC.

Both chips are old C2 revision chips. Not C3 where clocks are easy to come by. The x3 hit a max of 5.1ghz.

The board is a pretty much bottom of the line deal I got for around 15$.

In all I think the clocks are fine. Considering either chip on liquid is stable at maybe 3.8 to 4ghz at best.

Getting out around the forums a little more I see. Yes, I know who you are.

Yeah, poking around on some new places. Gotta help out on some different forums

I think you need to just work on some of the board voltages and clocks. A few chips on hwbot are doing 4.3-4.4 on water or phase so 5.0ghz+ should be easy with a better board or better board settings. As far as I can tell all of the 940 chips are C2 so there goes one excuse

Nice. See you around I'm sure, oh and welcome to EOCF.
