EVGA 780i SLI MCP TRing for for 4.50Ghz

[PorPorMe]

I'm running nice at 4.05Ghz but can't get it to 4.50G
The bios rill run it thru but Vista objects.

Is it time to start working on the memory? Just what will that do And which way do I go with it and why?
The G.Skills are rated CL4-4-4-12 1.8v~1.9v.
The bios sets it at CL5-5-5-15 2T. I've basicly left it alone except to raise the volts to 2.025v. So far 4.05 is stable. I put the shaders back to default on the video and that seems to have cured any problem. Ran Prime95 in a couple of different setups ( not long enough to be possitive, but will try for that tonite.)
I've been running ORTHO for about an hour with folding on and temps are 48-49c.

This is my set for 4.05Ghz.
Cpu Multy: x9
PCI-e: 100mhz
spp-mcp refclock 200mhz
HF Multi: both set for 5x
spread spectrums: all dissabled

FSB & Memory
FSB mem clock unlinked
FSB mhz: 1800mhz
mem: 800hz
mem timeings: what the bios wants -CL5-5-5-15 2T
not there rated cl4-4-4-12

SYS Volts
CPU Core: 1.336v
CPU FSB: 1.3v
Mem: 2.025v
SPP: 1.4v
MCP: 1.6v
HT:1.3v

Any improvements I can make? Gotta be!

It's a substantial jump to 4.50 from 4.05. Perhaps, just maybe.. 4.05 is impressive enough? I'd be happy with 4.05, fwiw. Typing this on a P4 machine at stock 3 Ghz. Yes, I have no shame.

Don't get me wrong, I'm happy with 4.05-even if I got 4.50 it wouldn't stay there long. Long enough to get a screen shot of OCCT and CPUID. But it's looking like I won't make it. I think that a person who knew his stuff, and was sitting at this keyboard, could do it. But me? probly not.

Hello there daniels co! You Photo wouldn't happen to be "Daniels Co." would it? Don't answer that question, You might incriminate yourself!
Welcome to AOA. You are welcomed here. If you have a question just ask away and somebody will come along with the answer. There are some skilled people here but you have to keep in mind not everyone visits the board every day and some of the good one are at different parts of the world. Be patient and you will get your answer.
Maybe you can be talked into the Folding team-we can use another rig! Just click on my sig and come on back and go through Samuknows Folding Team. Ask away, If you are interested. Either way you are still welcome!

Wasting your breath.

Got to be a bot, look at the post history....

PS you've done well to get to 4G, but without a bigger multi you won't get it to anywhere near 4.5G...what you are asking for is to run 500FSB x 9 which I don't believe possible on your board[nor many others either].

Even the E8500 has a multi of only 9.5 which would only get you to 4.2 odd. If you are very lucky you might get 460-465FSB x 9 and that would be impressive at nearly 4.2G. To get to where you want you'd really need a 10 or preferably an 11 multi.

I have seen some reports of 4.5G on some ASUS boards with difficulty[Striker, P5K and Maximus] but I don't know how yours stacks up; maybe, maybe not. You should try setting the memory to 1:1, [you are on a divider now] lowering the multi to 8 and seeing how far you can go with the FSB; if you can get to 8 x 500FSB = 4G - well, then there might be a slight chance of getting close.

[PorPorMe]

I can have whatever FSB I want. for 4.5g it's set at 1800mhz. trying for 4.50 I set it at 2000mhz. All the numbers change to reflect what it's going to be when when you get things set right. I've tried many combinations of CPU core volts and,CPUFSB, Memory, ssp, [northbridge] and MCP [southbridge] and HT SSP <->MCP. I can get it to boot at 4.50 but as soon as I hit Vista-I'm done. I get a blank screen or I have gotten Vista to start bu just for 30sec or so.

[ThunderRd]

As I said before, if you want to have a chance at success, you have to find out at what point the box craps out.

Set the memory to 1:1, and raise the FSB in small increments until Vista will not start. Then back off a few MHz and stress it for stability. This is your highest FSB possible without the memory being a factor. Then you go from there, and make changes in another variable to get higher values. It's not a hit-or-miss procedure where you try various combinations that may or may not work; it's scientific and systematic. At least for me it is. I'm not good enough to let my OC mojo instinctively tell me how to set up everything. I have an idea where to start, sure -that came after doing it for many years - but for me it's still a very slow process to get things right.

Remember that FSB isn't the only thing that affects your desktop "experience" - a somewhat lower FSB with tighter memory timings is most likely a quicker rig than a high FSB with loose timings. That's why you have to quantify accurately the point at which you have problems. It's your reference point.

It looks like you are using some kind of auto-OC feature where "all the numbers change". My feeling is that if you are to get a really high OC you will have to dump that system and use the manual settings. I, for one, have never had good results from canned overclock settings[example-you set the FSB and the BIOS sets everything else]. For one, they normally pump far too much voltage than you really need to get there - this is by design, to make it easy for less experienced users.

I said that wrong about all the numbers changing. If I put in any x FSB and/or x multiplier it does the math and tells me what Ghz I am looking at with those numbers plugged in. It does nothing in the way of guidance for what else to do. At 9x 1600 FSB =3.60GHZ- 1800 FSB =4.05Ghz - 2000 FSB = 4.50Ghz.

Thanks for posting what you did, that is exact what I needed to know. I may take another crack at it tomorrow but at this moment I'm inclined to let it go until I get back from the hospital.

hospital, man you alright?

I picked the absolute perfect time to come back here and check! I had not realized it had been so long! The hopital stay went as well and better than expected. I have been healing quite well but it takes almost a year to fully heal from this.
But I've been so damn busy this is the first time I've been up in this thread since the hospital.
Things have changed a bit if you remember. My sig just keeps changeing.
The reason i came up here to post was I have to tear mine back down agian. I just got it back together after a fun mod. Pics are down in the mod section.You might get a laugh out of them. Anyway, I've got a bad install of most of my HS. Temps are just unacceptable for such a weak OC. I can't do anything untill next month as I am out of thermal compound.
I took a quick glance at the link. Is that yours or just what am i looking for? Forgive me-it was a quick glance.
This is the reason I have to tear mine down agian!

I guess you've gotten pretty used to having the E8400 & much higher clock speeds heh PPM...

I can't even get my system stable at 3.60GHz & you are calling it a
"Weak" OC! LOL

My next upgrade with be to the Core i7 system with the x58 chipset or whatever chipset will be newer then in about 4-5 years
(Or more) from now.
Then I'll see about what kind of clock speeds I can put up then...
But yea, your NB temps are really high! Mine is at 80F.

[PorPorMe]

Tha one that yells is the SPP, but it's a bad install all around. I must have been in to much of a hurry and I'd removed the aftermarket junk that was on it and re-installed the OEM Chipset system-except for the MCP. And the reason this boad is something for OC'ing AND the reason I know it's a bad install-I didn't up the volts on anything.
I'd never set the FSb at 1600 befor so what the heck, lets see about that with no voltage change.. I know that 1700 (3.85G i think) I just have to bump the volts just a little-CPU Core and CPU FSB. Everything else i leave alone untill I get to 4.00G once all the hardware is up to snuff. I did some diagnostics yesterday and my memory is weak. Good-passes memtest, but cheap memory.
I wen't and and got the approved list from EVGA and a lot of odd ball name brands. Of the name brands-which re few are OCZ which ccp said he wounld not buy an Kingston, which i wont buy.
There is some time to do some reserch.

And I can see why you like Win 7-this is nice!!

I took a little time this mirnig to go thru your link. Some nice stuff.
I painted aircraft parts for a while and while it's not what custom painting is, it's a lot more complicated than most even think about and gave it a long thought about going into custom painting.
There was just one thing that got in the way. 90% of custom painting is learned in custom auto shops. The big snaffu- I can't do body work. It is realy strange, my eye can read the the paint but I can bairly see the body work.
So I moved up in the company I was in, got my A&E lic. and worked aircraft.
Now I play computer!
